Title: Line pressure control device for automatic transmission
Inventor: ISHIKAWA KAZUO
IPC: F16H59/24
Filed: 1990-03-29
Abstract: PURPOSE:To increase engaging force of a frictional engaging element during starting at a second range by providing a throttle modulator valve to regulate a second range pressure inputted from a manual valve to output it as a throttle modulator pressure. CONSTITUTION:When a manual valve 23 is in a second range state, a second range pressure is inputted to a port 40a of a throttle modulator valve 40 through an oil passage L7. The second range pressure is regulated to a pressure equivalent to the force of a spring 40D, and is regulated to a value higher by an amount equivalent to a throttle pressure inputted through the port 40b. Thereby, a throttle modulator pressure outputted through a port 40c to a change valve 50 is always increased to a value higher than a throttle pressure. As a result, a throttle modulator pressure is introduced from the valve 40 to a boost chamber 27A of a primary regulator valve 27, in order, through an oil passage L9, the change valve 50, and an oil passage L12, and regulation of a line pressure by means of the valve 27 is performed based on a throttle modulator pressure.

Title: Image reader
Inventor: IZUMIKAWA MANABU
IPC: H04N1/04
Filed: 1996-03-07
Abstract: PROBLEM TO BE SOLVED: To stop a movable part for scanning a document stably at its home position when the movable part is scanner motor. SOLUTION: When the power source is turned on, a microcomputer performs a process for HP detection with each of excitation pattern switching pulses of the scanner motor 7 and then moves the motor in its return direction by a set number of pusles (e.g. 10 pulses), thereby stopping it. The microcomputer performs the process for HP detection for every 20 pulses not at the power-ON time. For the HP detecting operation, when an HP sensor 8 is ON, namely, when the light shield plate 9 of a 1st carriage C1 is positioned in the detection area of the HP sensor 8, the light shield plate 9 is moved forward out of the detection area of the HP sensor 8 by driving the scanner motor 7 forward. When the HP sensor 8 is not ON, the scanner motor 7 is drive in its return direction and the output signal of the HP sensor 8 is monitored in one-pulse or 10-pulse cycles.

Filed: 1985-04-15
Abstract: PURPOSE:To effectively discriminate the OFF defect of a diode with a simple structure by detecting the OFF defect of diodes of 3-phase full-wave rectifier by utilizing that a peak state is not generated. CONSTITUTION:A current detector 13 detects a phase current and supplies it through an amplifier 14 to a peak value counter 15. A line voltage detector 17 detects the interphase voltage of 3-phase AC power sources R, S, T and supplies it to a peak value counter 15. The counter 15 controls a malfunction detector 15. Thus, the OFF defect of the diodes which form the full-wave rectifiers can be detected by utilizing that the peak states of two are not generated in zones of 0-pi and pi-2pi when any of diodes which form the 3-phase full-wave rectifiers is OFF defective.

IPC: G11B15/10
Filed: 1989-03-30
Abstract: PURPOSE:To automatically perform temporary recording and stopping by freely setting a recording temporarily stopping time with the aid of a recording temporarily stopping time setting means and displaying an elapsed time or remaining time for the set means as a display time. CONSTITUTION:The recording temporarily stopping time is set at a desirable value by the recording temporarily stopping means setting volume 1 of a video tape recorder. When a temporary stopping switch 6 is depressed, a recording temporarily stopping signal from the switch 6 is received by a system controller 3 and a tape feeding stopping signal f1 is transmitted to a tape feeding mechanism by a CPU, so that recording is temporarily stopped and the temporary stopping is cancelled with the output of a counter. A display control circuit 10 displays the elapsed time or the remaining time for the means set by the volume 1 on a display circuit 11 under the control of a controller 8. Thus, the recording and stopping is automatically performed in the video tape recorder.

Abstract: PURPOSE:To realize the transmission of data with an average queueing time required for transmission, by performing the transmission of data by utilizing other channel when a transmission data exists for more than a fixed time. CONSTITUTION:When a transmission data is generated, a request event for transmission is passed to a queue selector controlling part 10 in a terminal T1. The controlling part 10 searches each transmission queue train 8a-8n and passes the transmission event to a queue train which has the least transmission events. At this moment, the control part 6 grasps the queueing time of transmission events in queue trains 8a-8n and picks up a transmission event, which is queueing for more than a fixed time, to transfer it to a time-out queue part 7. On the other hand, it sends a command to a transmission controlling part 5 for all channels except a channel which is in the operation of transmission, to perform an operation for acquiring a transmission right. If the control part 5 gradually acquires the rights, the control part 6 gradually picks up transmission events and starts to perform transmission operation.

IPC: H04N5/455
Filed: 1990-03-27
Abstract: PURPOSE:To reproduce a video signal with fidelity by setting a phase detection sensitivity of a PLL loop lower for a video period. CONSTITUTION:A PLL consists of a phase detection circuit 10, a DC conversion filter 206 and a voltage controlled oscillator 208 and the detection sensitivity of the phase detection circuit 10 is controlled smaller for a video period of a video intermediate frequency signal than that for other periods. Thus, a signal for a period whose value is unchanged depending on the video content such as a synchronizing signal portion or a blanking period portion is mainly subject to phase control by the PLL, and a phase of a reference signal by the PLL is less affected by the video content. Thus, the video image is reproduced with great fidelity.
