Patent JP-H03118768-A (JP)
Title: Power source circuit
Inventor: FUJII HIROSHI
IPC: H02M7/12
Filed: 1989-09-30
Abstract: PURPOSE:To reduce the rush currents in power making so as to decrease the loss in normal load operation by inserting an impedance element in series with a Schottky circuit for a certain time after power making. CONSTITUTION:When power is made, rush currents flow to the capacitors C2 and C3 of a Schottky circuit 3, but at this time a switch element 6 is open, and an impedance element 5 is inserted in series to the capacitors C2 and C3, so it follows that charge currents flow gradually, and rush currents are reduced. When a certain time passes after power making, a timer circuit 7 drives the switch element 6 to close the path, and by the close of this switching element 6, the impedance element 5 inserted in series with the capacitors C2 and C3 is short-circuited. Hereby, in the normal load operation after a certain time has passed since the power making, the loss by the impedance element 6 can be reduced.

Title: Actuator driver
Inventor: TAKEUCHI KANJI
IPC: H02P8/00
Filed: 1991-09-06
Abstract: PURPOSE:To ensure high response in an actuator and to realize silent operation with no chopper noise. CONSTITUTION:Current flowing through an actuator winding L is detected and a subtractor 2 compares a winding current signal IL with a set current signal IS thus detecting a difference. The difference signal is subjected to proportional integration through a compensator 3 and then compared with a triangular wave and modulated into a duty pulse signal in inaudible frequency region. The pulse signal is damped to have a predetermined magnitude and then it is superposed on a set current signal. Thus superposed signal is compared through a comparator 6 with the winding current signal and a transistor 8 is operated according to the comparison results thus conducting the winding L. When the difference between the set current signal and the winding current signal is large, the superposed duty pulse signal makes no contribution and the transistor 8 sustains ON or OFF state and thereby the winding current approaches quickly to the set current. When the difference decreases, the duty pulse signal begins to make contribution and the transistor 8 is turned ON/OFF in an inaudible frequency region without producing chopper noise.

Title: Indoor ventilation method
Inventor: TANAKA YOSHIAKI
IPC: F24F7/04
Filed: 1987-10-09
Abstract: PURPOSE:To provide an indoor ventilation method of which installing expenditure and maintenance expenditure are less expensive and a silent ventilation of an entire room can always be carried out and further it may be operated even under no air condition by a method wherein more than two ventilation ports having a heating source are attached to a slant or vertical aeration circuit. CONSTITUTION:Ventilation ports A with a heating source are constructed such that a heating source 2 such as heater and the like is set at a slant aeration circuit 1. So, when surrounding cold air enters a room 4 through ventilation ports having a heating source, the air is heated and thus an interior temperature is not decreased. An aeration circuit 1 at the ventilation port A having a heating source at the lower part of the room 4 ascends from outside toward an interior of the room. Due to this arrangement, surrounding atmosphere is taken into the indoor area through heat of the heating source 2 and then ascending air flow is generated. In turn, the aeration circuit 11 for the ventilation port A having a heating source attached to the upper part of the room 4 ascends from an interior side to the outside part. Due to this fact, indoor air is discharged due to heat of the heating source 2 and then the ascending air flow discharged out of the room is generated. Thus, in case of no air, an air flow indicated by an arrow is generated and ventilation of the interior area is carried out.

Title: Feedback control device of stepping motor
Inventor: FUKUSAKA TETSUO
IPC: H02P8/14
Filed: 1997-09-04
Abstract: PROBLEM TO BE SOLVED: To correct and reduce the irregularity in a rotary speed in real time, by monitoring the rotary speed of a stepping motor and generating a control signal for bringing closer to a target value and at the same time varying the rotary speed in real time. SOLUTION: A reference signal is outputted from a reference signal generator 400 to a phase signal generator 401 for creating a phase signal and a ROM 402 with a micro step pattern table. A phase signal being created by the phase signal generator 401 is outputted to a motor driver IC 404, and a micro step pattern being outputted from a reference signal and an acceleration/deceleration signal from an acceleration/deceleration information generator 409 is determined in the ROM 402. A speed difference to a target value is detected from the output of a rotary encoder 406 being mounted to a motor shaft by a speed difference detector 407, and the speed difference is converted into a control signal by a control device 408. The control signal is outputted from the acceleration/deceleration information generator 409 to the ROM 401 as acceleration/deceleration information.  As a result, in all stepping motors, feedback control is made, thus correcting wow/flutter in real time.

IPC: B41J11/42
Filed: 1988-10-12
Abstract: PURPOSE:To reduce the consumption of an ink film by providing a speed control means for increasing a paper feed speed in response to a detection signal when printing data is blank by one line and an ink film feed prohibiting means. CONSTITUTION:A thermal transfer printer is constituted inclusive of a printing buffer 7 for storing and judging the content of printing data. When the printing data enters the printing buffer 7, a stepping motor 1 is operated to start printing. Further, a paper feed roller 2, a transmission belt 3 and transmission roller 4 are operated in connection with said motor 1. In parallel to this operation, the content of the data of each line of the printing data is successively searched by the printing buffer 7. When the printing content of a lateral one row, that is, one line is entirely blank, a signal is sent so as to turn a solenoid clutch 'OFF' and an ink film 8 becomes a stop state. At this time, a signal of a doubling speed is sent to the stepping motor 1 and the speed of the paper feed roller 2 is increased to the doubling speed to shorten a printing processing time. By this method, a time for the printing output of one paper is shortened and the ink film is used efficiently to make it possible to reduce the consumption of the ink film.

Title: Non-volatile semiconductor memory
Inventor: IHARA MAKOTO
IPC: G11C14/00
Filed: 1993-10-14
Abstract: PURPOSE:To prevent data of a memory cell other than a selected memory cell from being destroyed. CONSTITUTION:Potential of bit line BLi and the inverse of BLi which are not selected at the time of read-out is made the same potential as the other electrode of a capacitor. Further a power supply of a sense amplifier 3 connected to the bit line BLi and the inverse of BLi which is not selected at the time of readout is cut off. Thereby, data of a memory cell 6 corresponding to the bit line BLi and the inverse of BLi not selected is not destroyed at the time of read-out. Therefore, since rewriting the bit line BLi and the inverse of BLi not selected including almost bit lines BLi and the inverse of BLi after read-out is not required, power consumption of a non-volatile semiconductor memory is largely reduced.
