Patent JP-H01215178-A (JP)
Title: Image forming device
Inventor: SAKAI MASAHIKO
IPC: G03G15/04
Filed: 1988-02-23
Abstract: PURPOSE:To improve a defect such as deviation of image caused due to malfunction by outputting each synchronizing signal from each beam detector as the synchronized signal while asynchronization is corrected when signals are not synchronized. CONSTITUTION:For example, in case a signal BD1 is at H and a signal BD2 is at L, when an error signal E goes to H, the signal BD1 is outputted with a delay of a time T1 from a delay line 17 and an AND gate 19 is enabled. That is, a synchronizing signal BD 1 delayed by the time T1 through the delay line 17 passes through OR gates 20, 21 in a form compensating the asynchronous signal and horizontal synchronizing signals BD1', BD2' corresponding to each color are ouptutted at the same time and a video signal of each color is outputted synchronously with the horizontal synchronizing signal. Thus, a problem of occurrence of a defect such as deviated image due to unsynchronized scanning of the laser beam corresponding to each color in the formed picture is avoided.

Title: Signal system
Inventor: SHINTANI KATSUMORI
IPC: H04B1/40
Filed: 1984-03-02
Abstract: PURPOSE:To improve squelch operation by utilizing an ATIS (Automatic Transmitter Identification System) signal modulated to a transmission signal of a personal radio equipment or the like to add a kind of an identification signal to the ATIS signal. CONSTITUTION:In a radio system transmitting automatically an identification code such as ATIS signal at the start, middle and end of talking, the identification signal 10 representing the middle to the ATIS signal at the middle other than the start and end of the talking is added. A receiver identifies the ATIS signal and also detects the identification signal 10, neglects the ATIS signal with respect to squelch function for a prescribed time from the carrier leading and the squelch function is closed by taking it as the notice of carrier interruption if no identification signal 10 is detected in the succeeding ATIS signal. Since a sound output circuit is closed already for noise generated at carrier interruption, no noise is outputted from a speaker. On the other hand, since the ATIS signal is not identified against momentary electric field reduction such as fading, the squelch function is not interrupted.

Abstract: PURPOSE:To restrain sudden increase in a current and reduce the consumption of current by providing a one-shot multiple circuit in the DC-DC convertor of an ignition device of an internal-combustion engine and feeding a primary current to an ignition coil later than a power switching element is turned off.

In a low speed range in which the OFF time of a power transistor 3e is longer than a one-shot time, the DC-DC convertor 20 operates only during the one-shot time. Conversely, in a high speed range in which the OFF time is shorter than the one-shot time, the DC-DC convertor 20 operates only during the OFF time. Thereby the sudden increase in a primary current in an ignition coil can be prevented reducing the consumption of current of the DC-DC convertor.

Filed: 1988-02-24
Abstract: PURPOSE:To eliminate the limit of the mounting number of LSI for communication on a communication control equipment by preparing a status area for reporting operation to each group after dividing a required number of LSI for communication into plural groups. CONSTITUTION:LSI for communication of a number of <=2N are assigned to each of plural groups 4 and 5 by setting the maximum mounting number at 2N and, at the same time, a status area 7 is provided on each group 4 and 5. For each group 4 and 5, N-bit peculiar identification numbers which can be used only in each group are assigned to the LSIs for communication constituting respective groups 4 and 5, but, since the LSIs make access to only the status areas 7 prepared for respective groups 4 and 5, LSIs for communication of a number of >2N can be mounted on the communication control equipment. Therefore, the limit of the mounting number of LSIs for communication on the communication control equipment is eliminated.

Title: Semiconductor light-emitting device equipped with light isolator
Inventor: ODAGIRI YUICHI
IPC: G02B27/28
Filed: 1987-02-23
Abstract: PURPOSE:To reduce an insertion loss and to enhance an isolation characteristic by a method wherein a semiconductor photodetector having a wave-guide path of multiple quantum well structure is used as a photodetector for a light isolator. CONSTITUTION:A beam of light from a semiconductor laser 1 is converged by a lens 11 and is injected into a semiconductor photodetector 14 after its polarization plane has been turned by 45 deg. with a Faraday rotor 13. The photodetector 14 is equipped with a wave-guide path, of multiple quantum well structure, whose incident and outgoing faces are coated to be nonreflective, and amplifies a TE polarization component selectively. After the laser beam has been amplified with the photodetector 14, it passes through a lens 12 and enters an optical fiber 2. By this setup, an insertion loss of a light isolator composed of the Faraday rotor 13 and the photodetector 14 can be reduced. Only the TE component of the beam of light returned from the optical fiber 2 is amplified with the photodetector 14; furthermore, the beam of returned light is turned by 45 deg. by the rotor 13. Because the beam of returned light is returned to the laser 1 in the form of the TE component which has been turned by 90 deg. with reference to the TE component of the laser 1, it does not disturb a laser oscillation.
