Abstract: PROBLEM TO BE SOLVED: To reduce the power consumption of a portable communication transceiver and to prolong the operation life of the tranceiver battery. SOLUTION: Directional antennas 102 and 102' connected to the portable communication transceiver are directed adaptively to a remote station in a communication system. The high frequency output quantity required by the portable device for nondirectional antennas is greatly reduced. Consequently, the time for which the transceiver 210 operates until battery recharging is greatly increased.

Abstract: PROBLEM TO BE SOLVED: To provide a method of coating a polymer on a square or other non- circular substrate which avoids forming a thick film, without using the polymer wastefully. SOLUTION: The process of coating a polymer on a substrate surface comprises heating a polymer soln. at a pre-selected lower temp. than the flash point of the soln., storing the polymer soln. in a store tank 16, extruding it through a nozzle 14 to form a stationary continuous flow of the soln. which flows from the nozzle 14 back to the tank 16 and again flows out through the nozzle, and moving the substrate 12 having a lower surface at a pre-selected speed over a stationary wave 18 so as to contact the lower surface to this wave 18, thereby coating a uniform film of the polymer on the substrate lower surface.

Abstract: PROBLEM TO BE SOLVED: To provide a device and method for allowing a signal detector such as a computer system to generate an electrostatic signal by means of a tablet and a touch pen which can be manually operated linking with this tablet. SOLUTION: This device is provided with an electrostatic input pen 13, and a top end 14 of the pen 13 linked with a table 20 is made conductive and flexible, and according as the top end 14 of the pen 13 held by a hand is pressurized on an uppermost insulating layer 12 of the table 20, a contact area with the table device 20 can be enlarged. Also, signal source 14 and a signal detector 50 are connected in series between the top end 14 of the pen 13 and a lower conductive layer 11 of the tablet 20. Therefore, the enlargement of the area in contact with the top end 14 of the pen 13 increases capacitance between the top end 14 and the lower conductive layer 11 of the tablet 20, so that the S/N of a detection signal can be improved.

Abstract: PROBLEM TO BE SOLVED: To realize a circuit and method to generate a clock signal having the same frequency as that of a crystal whose duty cycle is adjusted to a stable duty cycle. SOLUTION: The circuit is made up of a clock generating circuit 16 connecting to a crystal 12 and converting a 1st signal from the crystal 12 into a clock signal and a duty cycle control circuit 18 that generates a feedback signal to change a duty cycle into a stable duty cycle. A clock control circuit 14 may have an output pad so as to decide the duty cycle with a measurement device.

Abstract: PROBLEM TO BE SOLVED: To reduce a power consumption amount of a CMOS circuit by providing a circuit that is provided with plural FETs and a means which prevents current from simultaneously flowing through the FETs. SOLUTION: A pair of MP2 AND MN2 devices 16 and 18 is serially connected to MP1 AND MN1 devices 12 and 14. When an input signal VIN gradually starts to rise during transition from low to high, and a buffer 22 converts it into a fast rise pulse that appears on an output side and operates as a circuit which forms a waveform through this. The fast pulse cuts the MP2 before the MP1/MN1 inverters reach a trip point and flow of passing current is interrupted. The same matter occurs when an input signal transits from high to low. The buffer 22 cuts the MN2 before the MP1/MN1 inverters reach the trip point, also in this case, the negative transition of an input signal reduces the flow of passing current.

Abstract: PROBLEM TO BE SOLVED: To provide a Schmitt trigger circuit which is improved to establish a hysteresis without using any feedback mechanism. SOLUTION: The hysteresis tripping point of an improved Schmitt trigger circuit 10 is decided in two input inverter steps (steps 1 and 2). In the first step 1, various Schmitt trigger circuit levels can be generated by changing the ratio between inverters 12 and 14. In the first step, in addition, hystereses become independently controllable by tripping points of the inverters 12 and 14.

Abstract: PURPOSE: To considerably change the frequency range of a delay cell and to realize multiplex range VCO by changing the delay cell of a ring oscillator, to add a current supply source to a booster inverter and to selectively increase/ decrease current. CONSTITUTION: The delay cell is basically a current control converter. The transmission delay of the respective cells changes by changing current to the delay cell and the frequency of ICO changes. The booster inverter constituted of four FET transistors 40, 42, 44 and 46 is incorporated in a main current stub inverter and therefore the stronger delay cell is realized. When the strength of the booster inverter increases, the frequency range of VCO shifts to the higher frequency. When the strength of a booster decreases, the frequency range of VCO shits to the lower frequency. For realizing the wider operation frequency range, plural voltage control current sources 50, 52, 54 and 56 are mounted and current to the booster inverter is restricted.
