Abstract: PURPOSE:To realize simple and safe position setting of a driven object by constituting a linear motor of a predetermined part of the driven object and a guide body. CONSTITUTION:A driven object, i.e. the traveling member 16 of a spot light 2, is built freely movable on a rail 7. Consequently, current collecting electrodes 19a, 19b are respectively connected electrically with power supply electrodes 20a, 20b, weight of the spot light 2 is exerted on rollers 18a, 18b which thereby come into contact with the inside part of the rail 7 thus making the spot light 2 movable longitudinally on the rail 7 through rotation of the rollers 18a, 18b. In order to drive the spot light 2 longitudinally on the rail 7, a linear motor is constituted of the rail 7 and the traveling member 16. According to the constitution, position setting of the spot light 2 can be realized easily and safely.

Abstract: PURPOSE:To compensate oscillating frequency fluctuation attended with temperature change by providing a transient temperature correction circuit generating a temperature correction signal representing the same characteristic as the temperature characteristic in the inside of an IC when temperature is fluctuated with on/off of power to a voltage controlled oscillator circuit as a temperature compensation circuit. CONSTITUTION:When a power Vcc is applied and the internal temperature of the IC rises along a curve K0 at a point of time t0, a voltage of a capacitor C21 rises with a charging current flowing to a resistor R21 of a transient temperature correction circuit 25 with the same time constant and the capacitance of varactor diode D31 of an adjusting signal generating circuit D26 is controlled in a direction cancelling the change in the curve K0 so as to compensate the change in the oscillating frequency of a VCO11. When the power Vcc is cut off at a point of time tOFF from the steady state, the charging voltage of the capacitor C21 is discharged with the similar change as a curve K1, and the capacitance of the diode D31 compensates the change in the oscillating frequency of the VCO11. The circuit 25 is operated similarly even when the power is cut off before the steady state is not attained after the power supply ON at points of times t01, t02, t10. Caption 22 is a steady-state temperature correction circuit.

Abstract: PURPOSE:To prevent data from being erroneous due to crosstalk and to make high- speed access possible, by performing decision for the address, tracking, and so on before a rotary head scans the objective data track. CONSTITUTION:Magnetic tape 10 where address information, tracking information, and so on are recorded previously on tracks 17 and 16 along the upper end and the lower end is used, and tape 10 in the stationary state is scanned obliquely by rotary heads 13E, 13W and 13R arranged on the outside circumference of drums 11 and 12 which are provided in the running path of this tape 10. Then, tape 10 is caused to run up to objective data track 19 intermittently, and tape feed is completed during one rotation of rotary head 13, and further, signals reproduced from tracks 17 and 16 are used to perform decision for the address, tracking, and so on before the rotary head scans this data track 19.

Abstract: PURPOSE:To prevent erroneous read due to crosstalk to use the data track effectively, by arranging writing, reading, and erasing heads at proper intervals when the rotary head adapted for the bulk recording system of the computer is obtained. CONSTITUTION:On tape 10, servo track 17 and address track 16 are recorded in the lengthwise direction, and data track 19 is recorded obliquely to the width direction. The tape is wound around drum 11 at approximately 180 deg.. This tape is caused to run up to the object position, and in the static state, the rotary head scans track 19. In the rotary head, reading head 13R and reproducing head 13W are arranged at the angular interval equal to the magnetic tape winding angle for the drum, and erasing head 13E is arranged in the position preceding the recording head. Tracking detection is performed by the oblique-line part of address signals An+1, An, and An-1 reproduced by the erasing head and address detection is performed by center An.

Abstract: PURPOSE:To read braille points only by placing the tip of a finger at fixed reading locations, by projecting the right row side of dot portion materials corresponding to one unit as delaying the right row side more than the left row side in time while successively altering the projecting conditions of the dot portion materials corresponding to one unit. CONSTITUTION:Dot portion materials 10A-10F for braille points corresponding to one unit go into and out from small holes 12A-12F by means of drive mechanisms 20A-20F starting in response to dot signals. The dot portion materials 10A, 10B, 10C at the left row side among the dot portion materials are brought to fixed projecting conditions in response to each dot signal from a control circuit, and the dot portion materials 10D, 10E, 10F at the right row side are changed into fixed projecting conditions for a limited time after retardation time, thus displaying braille points characters corresponding to one character. Thus, projecting conditions are successively shifted in the dot portion materials displaying braille points characters corresponding to one character so that all portion materials be returned to immersion conditions after a fixed time elapses and the next, new braille points character be indicated.

Abstract: PURPOSE:To make the discrimination between two input voltage by a simple circuit, by detecting the absolute value of the difference between two input voltages and by setting the thereshold level of its center value by changing the ratio among several resistors for the stable opration of this circuit when IC-implemented. CONSTITUTION:Input voltage V1 to the 1st input terminal 1 is connected to resistor RA, whose one terminal is connected to constant-current supply 5, via transistor Q1 constituting the 1st voltage detector, and input voltage V2 to the 2nd input terminal 2 is to resistor RB, whose one terminal is connected constant-current supply 5, via TrQ2 constituting the 2nd current detector. Setting resistance values of resistors RA and RB in this constitution determines threshold voltages VE1 and VE2, thereby making the discrimination between the 1st and 2nd input voltages V1 and V2. By this circuit, the dispersion of a circuit when IC-implemented is reduced for stabilization.

Abstract: PROBLEM TO BE SOLVED: To make a power adapter compact when it is not used and improve transportability and portability by providing a winding body in the casing of a power adapter, and winding an electric cord after power is fed. SOLUTION: An input wire winding mechanism 1 winding an input electric cord 101, an output wire winding mechanism 2 winding an output electric cord 102, and a power circuit 3 are provided in a casing. When the electric cords 101, 102 are pulled, bobbins 13 of the input wire winding mechanism 1 and the output wire winding mechanism 2 are rotated, and the electric cords 101, 102 are extracted by the required lengths. Protruded contact points 15 a, 15b are rotated in contact with ring contact points 16a, 16b, and a power transmission path is not interrupted. When plugs are removed from a power source and an apparatus after the power feed is finished, the bobbins 13 of the input/ output wire winding mechanisms 1, 2 are rotated in the reverse direction by the restoring force of coil springs 14, and the input/output electric cords 101, 102 are wound on the bobbins 13.

Abstract: PURPOSE:To make it possible to use an ordinary voltage converter whether it is a dimmer type or not. CONSTITUTION:Since a dimmer circuit 4 controls the feeding power to a halogen lamp 6 at the output side of a converter 2, not only an electronic transformer which can dim at the primary side, but also an electronic transformer which cannot dim at the primary side can be used as a converter 2. Power can be fed to a motor to rotate the lamp 6, for example, from the output side of the converter 2. Consequently, the cost can be reduced, a lighting system including the lamp 6, the motor, and the like, can be made compact, and its high function can be realized.
