Title: Device and method for data transfer
Inventor: NISHIMURA TAKUYA
IPC: G06F13/38
Filed: 1992-01-20
Abstract: PURPOSE:To provide the data transfer device capable of normal data transfer even though the operation of signal lines related to the hand shaking is performed during clock input and output. CONSTITUTION:At the time of data transfer, a chip select signal is outputted to a reception microcomputer through a D latch 305 of a terminal control means 30 by receiving a chip select instruction. Based on the clock from a clock supply means 111, the data of a transmission buffer 107 is serially transferred through a data line 103. During the transmission, the output of an instruction is not sent to the reception microcomputer 102 even though the instruction stopping the chip selection comes and the chip selection is stopped at the end of a unit of data transfer.

IPC: H04W8/22
Filed: 1999-02-08
Abstract: PROBLEM TO BE SOLVED: To provide a function of security to a telephone network itself by detecting both prescribed 1st and 2nd conditions of a caller terminal and a called party terminal and connecting the caller terminal to the called party terminal only when both the 1st and 2nd conditions of them are coincident with each other. SOLUTION: Both a 1st condition S17 denoting whether or not a caller terminal makes a call from a specific place and a 2nd condition S16 denoting whether or not identification information of the caller terminal is coincident with identification information of a specific PHS terminal are checked. In the case that either of connectable PHS number data D11, D13 is coincident with PHD number data D20 of the caller PHS terminal, it is regarded that the connection is permitted and the processing proceeds to the S17. In the S17, data D21 (a radio zone number of the caller PHS terminal) received in the S14 are compared with data D2 received in the S11. Only when both the 1st and 2nd conditions S17, S16 are satisfied, the caller terminal and the called party terminal are connected.

Abstract: PURPOSE:To shorten the processing time for fault detection by deciding a sequence control to be performed next while utilizing the shifting time between writing and reading. CONSTITUTION:The magnetic disk medium 1 to be tested is driven for rotation through a spindle axis 2 by means of a spindle motor 3. A magnetic head 4 is fixed on an actuator 6 and waveform data for the test of the fault detection having a prescribed frequency are written on and read from the magnetic disk medium 1. An head IC 8 is driven by a driving circuit 9 and controls the operation of the magnetic head 4. An analogue processing circuit 11 receives the instruction from the DSP 12, compares the inputted a waveform data having the prescribed frequency with each slice value and reports the compared result to the DSP 12. Caused by the interruption by the index, the DSP 12 decides the various sequence controls to be carried out successively within the shifting time between writing and reading. The CPU 13 sets the sequence controls on the DSP 12 and after setting the numbers of times of retry and the fact whether the double slices are present or not, the CPU 13 sends the starting signal.

IPC: G03G15/04
Filed: 1986-02-14
Abstract: PURPOSE:To prevent securely a moving optical element from falling naturally with a component of force of its weight when a driving source is not powered on by moving the moving optical element reciprocally in an upward and a downward direction and holding an electric feeding circuit in a short-circuit state when the motor is powered off. CONSTITUTION:When a driver 31 begins to power on the DC motor 30, forward movement drive (a) or backward movement drive (b) along slanting guide members 16 and 17 of the optical moving element 15 is started. If the DC motor 30 is powered off in the middle of said forward or backward movement drive of the moving optical element 15 for some reason, a voltage Vcc applied to a terminal (t) falls to zero immediately and the contact of a relay Ry is therefore broken to short-circuit the electric feeding circuit for the DC motor 30. The DC motor 30, therefore, functions as an electric brake device and the moving optical element 15 is stopped and held stably at an in-movement position on the slanting guide members 16 and 17 at the powering-off time of the DC motor 30 without falling naturally.

Title: Ac phase voltage detection circuit
Inventor: SONODA SHINICHI
IPC: H02M1/08
Filed: 1984-02-21
Abstract: PURPOSE:To enable the detection of a phase voltage free from effect of any zero phase current by connecting dummy resistors star-connected to a three- phase AC circuit. CONSTITUTION:Dummy resistors 21-23 star-connected are connected to a three- phase AC circuit 3 while a variable resistor 24 connected to a control power source of an inverter is connected to the neutral point P of the dummy resistors. In addition, the phase voltage detection resistors 31-33 are star-connected and then, connected to the circuit 3. As a higher harmonic is generated with the operation of the inverter connected to the circuit 3, a zero phase current flows into the control power source via the resistors 21-23 and 24 and the potential at the point P varies with respect to the zero volt as reference potential of the control power source. But the potential at the neutral point P of the resistors 31-33 will not be affected by the zero phase current. Therefore, when a voltage divided properly is taken out from the resistors 31-33, phase voltages in respective phases can be obtained as potential from the zero volt as reference potential. The voltage thus divided is utilized as a phase voltage signal for the control of the inverter.

Title: Driving device for motor-driven shutter
Inventor: UMIGAMI SUSUMU
IPC: E05F15/10
Filed: 1992-02-18
Abstract: PURPOSE:To eliminate the need for a DC-AC converter to reduce cost and to make the device compact and lightweight. CONSTITUTION:The output shaft of an alternating current motor 14 for moving a shutter curtain during normal operation, and the output shaft of a direct current motor 12 for moving the shutter curtain in a direction to close the curtain at the time when smoke is sensed, are connected to each other by a coupling 28. During normal operation, the shutter curtain is moved by the alternating current motor 14, and when smoke is sensed, driving of the alternating current motor 14 is stopped to move the shutter curtain in the direction in which the shutter curtain is closed by means of the direct current motor 12. Thus, since the alternating current motor 14 and the direct current motor 12 can be switched from each other to be used, there is no need for a DC-AC converter.

Title: Slip control device for vehicle
Inventor: YAMAGUCHI HISAAKI
IPC: B60T8/88
Filed: 1988-02-15
Abstract: PURPOSE:To prevent wheel lock or sudden change on running condition for securing safety in running by providing an abnormality correcting means suppressing control on braking pressure when abnormal compression or decompression on braking pressure is detected. CONSTITUTION:A braking pressure control means of a slip control device prevents slip on driving wheel against a road surface from getting excessive with controlling braking pressure. When this abnormal compression or decompression on braking pressure is detected by a braking pressure abnormality detecting means, braking pressure control with the braking pressure control means is suppressed by an abnormality correcting means. Thus, when abnormality is generated on increase or decrease of braking pressure, abnormal increase or abnormal decrease on braking pressure is suppressed and wheel lock or sudden change in running condition is prevented. Therefore, safety under running can be secured.
