Abstract: PROBLEM TO BE SOLVED: To increase an air flow quantity in a condition in which a noise level is held within an allowable value by arranging adhesive materials on a root part which is brought into contact with a hub in a surface side and a back surface side of each blade, and appropriately differing each shape of blades, in a fan wherein a plurality of blades are mounted around the hub to be rotated. SOLUTION: In a fan 1, a plurality of blades 4 are mounted at equal clearances around a hub 3 fixed to a rotary shaft of a motor in a fan main body 2. In this case, adhesive materials 5 are arranged on a root part 4a which is brought into contact with a hub 3 of a surface side and a back surface side in the appropriate number of blades 4. Each shape of the blades 4 provided with the adhesive materials 5, and each shape of the blades 4 not provided with the adhesive materials 5, are differed from each other. Accordingly, a periodicity applied to pressure change of air is reduced by each shape of the blades 4, and noise is reduced. Even if the number of the blades 4 and rotating speed are increased for increasing an air supplying quantity, it is possible to hold a noise level of a fan 1 within an allowable value.

Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of abnormality in a battery switching circuit and to secute the safety of a system by arranging a temperature sensing means in the vicinity of a change-over switch, and when the switch temperature exceeds a prescribed temperature, interrupting the switching circuit. SOLUTION: The circuit is constituted so as to connect the gate electrodes of respective FETs1 to 4 to 1st and 2nd series circuits 10, 20 in order to switch 1st and 2nd battery packs 30, 34. A temperature sensor 50 is arranged in the vicinities of these FETs 1 to 4 and a node G is connected to ground so as to control the switching of the FETs1 to 4. When the temperature of the sensor 50 is increased, its resistance value is increased and a transistor(TR) TR5 is conducted. Therefore the collector of the TR TR5 is turned to low potential and its gate electrode is turned to a non-conductive state. Thus the node G is separated from the ground, the FETs1 to 4 are turned off and all batteries are separated. A level applied to an FET5 shuts down the system as a shut- down signal.

Abstract: PURPOSE: To improve the efficiency of a power unit and reduce the size of the unit by constituting a switching regulator by using a plurality of horizontal synchronizing pulse trains having different frequencies so that the regulator can work in a plurality of display modes. CONSTITUTION: A horizontal synchronizing pulse train having a selected frequency is supplied to a waveform shaping circuit 2 through a line 11. An automatic frequency control circuit AFC3 incorporates an oscillation circuit 3A and a synchronizing circuit 3B and, since the saw tooth wave generated from the circuit 3A is corrected to a saw tooth wave having a frequency which is a multiple times as high as that of the horizontal synchronizing pulse train impressed upon the circuit 3B, the circuit 3B becomes synchronous to the frequency of the horizontal synchronizing pulse impressed upon the circuit 3B by generating a feedback signal on a line 13A. The power control circuit 8 of a switching regulator type power source circuit 9 receives a pulse from a line 16 and a feedback signal from a line 17 and generates a switching pulse on a line 18. Therefore, a power unit can operate at a frequency which is several times as high as a plurality of horizontal synchronizing frequencies and, moreover, synchronously and the principal design parameters can be selected so that the optimum operating condition can be obtained.

Abstract: PROBLEM TO BE SOLVED: To provide a technique for improving display quality. SOLUTION: A gradation upper-limit value (n) and a gradation lower-limit value (m) displayed on the display screen of an LCD module are detected at specific intervals and the setting of a γcurve is remapped according to the range to dynamically remap a luminance distribution. Further, when the gradation upper-limit value (n) or gradation lower-limit value (m) increases, the peak value of the γ curve is immediately varied. When the gradation upper-limit value (n) or gradation lower-limit value (m) decreases, on the other hand, the peak value of the γ curve is varied on condition that the decrease lasts for a specific number of frames or more.

Abstract: PROBLEM TO BE SOLVED: To make a liquid crystal display panel and an input tablet part detachable even when an equipment main body is powered ON. SOLUTION: The portable information processing equipment is equipped with a support means which supports a liquid crystal display panel part detachably from the equipment main body 1A, a detecting means for its attaching/detaching operation, and 1st and 2nd connectors 61 and 62 which connect the liquid crystal display panel part and equipment main body, and when the liquid crystal display panel part and equipment main body are separated, the 1st and 2nd connectors 61 and 62 are connected by a cable. Once the detecting means detects the liquid crystal display panel part being detached, the output of a video signal from the liquid crystal main body side to the liquid crystal display panel part is disabled to cut off electric supply to the liquid crystal panel part, and the equipment main body interrupts the operation of the whole system after saving data needed to restart the task, thereby storing the application execution contents right before the liquid crystal display panel part is detached.
