Inventor: KAWACHI HIDETOSHI
IPC: G11B21/10
Filed: 1992-09-14
Abstract: PURPOSE:To position a head with high accuracy by an always stable positioning control operation by a method wherein a positioning filter is changed over automatically according to the characteristic of a control system. CONSTITUTION:On the basis of servo data which has been recorded on a disk 10 in advance, a positional error between the present position and the target position of a magnetic head 11 is generated, and the magnetic head 11 is positioned to the target position by the positional error signal. When an error between the present position and the target position of the magnetic head 11 exceeds a reference value, the positional error signal is frequency-analyzed inside a CPU 13, a positioning filter is generated according to an analyzed result, and the phase of the positional error signal is compensated by using the filter.

Title: Detection of recording medium and electrophotographic printer using this method
Inventor: MURASE KOJI
IPC: G03G21/18
Filed: 1988-09-30
Abstract: PURPOSE:To allow the accurate measurement of the passage time of a recording medium most approximate to the service life of a process unit by detecting the cumulative printing length of the recording medium by utilizing the rotating motion of a rotating member which rotates only when the recording medium is inserted. CONSTITUTION:Gear trains 24a... are extended along the lower surface side of a recording paper transporting path on a device body 2 side down to the underside of the position where a counter 16 is mounted. The detecting device is so constituted that a stepping lever 26 is oscillated to step a counter 16 by utilizing a projection 25 provided on the gear 24h mounted at the extreme downstream position of the above- mentioned gear trains at every one rotation of the gear 24h. The gear trains 24a... are so set with a speed reduction ratio that the gear 24h rotates every time when the resist rollers pass the recording paper of, for example, A-4 size. Relay gears 27a, 27b are meshed with the gear 24 to allow stepping of a total counter 28 provided to the device body 2 side so that the total cumulative printing length can be detected on the device body 2 side. The passage time of the recording medium most approximate to the service life of the process unit is accurately measured in this way.

Title: Charger for electric automobile
Inventor: TSUTSUI YOSHIKI
IPC: H02J7/10
Filed: 1993-09-30
Abstract: PURPOSE:To prevent overcharge and the like of an auxiliary battery by eliminating the signal lines for detection being connected with the terminal of the auxiliary battery thereby eliminating disconnection. CONSTITUTION:When a load 4 is applied through the use of an auxiliary machine, for example, output current I0 from a DC-DC converter 1 increases and thereby the voltage VR1 across a current detection resistor 9 connected between a rectifier circuit 3 and an auxiliary battery B2 increases. Consequently, the voltage VR at the voltage dividing point of resistors 76, 77 increases over a reference voltage Vref divided by resistors 74, 75 and thereby the output from a feedback amplifier 72 lowers to drop the potential at the inverted input terminal of a comparator 71 which outputs a pulse signal of high duty ratio upon receiving a signal from a triangular wave oscillator on the noninverted input terminal thereof. The pulse signal is inputted to a Tr 5 through a resistor 6 and the output voltage Vc of the DC-DC converter 1 increases as compared with a state VC1 where the load 4 is not connected.

Title: Rightness checking system
Inventor: MATSUDA SHIGEHARU
IPC: G06Q40/00
Filed: 1986-10-17
Abstract: PURPOSE:To eliminate a transaction medium manufactured so as to always decide OK, irrespective of the contents of an identification number, by inputting a correct identification number, and an identification number being different from the identification number, for the purpose of an inquiry, and discriminating that the rightness for using the transaction medium exists, when the corresponding output of a result of its discrimination is different. CONSTITUTION:The original decision logic answers as 'correct' with respect to an incorrect identification number, and answers as 'negative' with respect to the incorrect identification number. On the other hand, the abnormal logic answers as 'negative' with respect to a correct identification number, or answers as 'correct' with respect to the incorrect identification number. Among these two abnormal logics, the former becomes an action for making a transaction impossible, therefore, an actual damage is generated in case of the latter. Accordingly, for the purpose of a fail-saif principle, such as case as 'correct' is answered with respect to the incorrect identification number must be eliminated. When the identification number is checked by giving intentionally this incorrect identification number, and confirming that its answer is not 'correct', the reliability is improved.

Filed: 1984-11-20
Abstract: PURPOSE:To obtain automatically an announcement signal by switching a position of a tape player in operation into a position of a tuner when it is discriminated that the announcement signal exists to receive traffic information and switching again the tuner into the player when the announcement signal is lost. CONSTITUTION:The switch circuit 9 switches a sound signal from a tuner section 1 and the tape player 8 and transmits either sound signal to a sound amplifier circuit 10. While the player 8 is in operation, a channel selection data stored in a preset memory in response to a prescribed key operation of a keyboard 7 is transmitted sequentially to a channel selection circuit 2 and the presence of the announcement signal is discriminated at every transmission. When no announcement signal exists, the stand-by state to traffic information broadcast is continued. On the other hand, when the announcement signal exists, the circuit 9 is switched from the player in operation into the position of the tuner 1 to output the traffic information. When the traffic information is finished and the announcement signal is lost, the circuit 9 is restored to the position of the player 8.

Filed: 1997-09-10
Abstract: PROBLEM TO BE SOLVED: To suppress the discarding of the signals between the speech blocks sections to be reproduced and to suppress the missing of reproduction tones by controlling the reproduction velocity from a recording medium according to the writing state of a detected memory. SOLUTION: A memory I/F:6 writes the digital signals subjected to speaking velocity conversion processing and given by a DSP 5 into the ring memory 7 and applies the signals to the memory status terminal MS of a microcomputer 9. The computer 9 detects the writing state of the ring memory 7 by the presence or absence of the input to the memory status terminal MS and counts writing stop periods by incrementing an internal counter value unless the writing is in cause of action. When the count value attains the threshold value, the computer 9 applies a deceleration command to a motor driving circuit 17 and properly commands the reading out timing by the D/A converter 10. The reproduction velocity is decelerated and recording signals are reproduced.
