Title: Selective radio call receiver
Inventor: ASAI TAKAYUKI
IPC: H04W88/02
Filed: 1990-02-16
Abstract: PURPOSE:To reduce a mean consumption current by allowing a selective radio call receiver to extend a period of intermittent reception more than a period when the receiver is resident in a service area while the receiver resides at the outside of the service area and a radio signal cannot be received at a sufficient reception electric field strength. CONSTITUTION:With a power source switch 14 of a selective radio receiver turned on, a decoder 8 sends an intermittent reception control signal (e) turning on/off a constant voltage circuit 10 at a predetermined 1st period to the constant voltage circuit 10. Since it means that the receiver is at the outside of the service area when no preamble signal is received, it is informed to the decoder 8 by means of a comparison signal d('1'). Then the decoder 8 based on the notice applies ON/OFF control to the constant voltage circuit 10 by means of the intermittent reception control signal (e) to select the period of intermittent reception into a 3rd period longer than the 1st period thereby transiting the receiver to the intermittent reception mode at the 3rd period.

Title: High-frequency switching circuit
Inventor: NAKAKUKI JIYUNICHI
IPC: H03K17/725
Filed: 1978-03-27
Abstract: PURPOSE:To reduce the number of the component parts of the circuit by connecting the single snubber circuit in parallel to the switching circuit which features the periods to conduct simultaneously via plural switching means connected in series to each other. CONSTITUTION:The high-frequency AC current flows to load 8 by the ON-OFF operation of thyristor 2 and 4. Under this operation, the forward blocking voltage is applied to thyristor 4 at the instant when the current of diode 5 becomes zero with the overlap voltage of the snubber circuit set to zero (for example, both thyristor 2 and diode 5 conducting simultaneously). However, the dv/dt does not increases since sunbber capacitor 16 starts charging, and accordingly the blocking voltage of thyristor 4 does not increase. Thus, the single snubber circuit can give the same function as that obtained with two units of the snubber circuit.

Filed: 1989-02-15
Abstract: PURPOSE:To shorten the time required for maintenance of an on-line transaction processing system by reducing en bloc the data quantity of a data communication line via a data transmission quantity reducing part prepared independently of an application program. CONSTITUTION:The data output requested by each application program 2-1 is sent to a difference data extracting means 12 and a total data store means 11 of a data transmission quantity reducing part 1. The means 12 extracts only the part that is different from the data stored in a data memory area of a display screen memory means 10 corresponding to a terminal equipment 3-1 of a sending address in the data. Then a data output means 13 sends the extracted data to a terminal equipment of the receiver side via a data communication line. The equipment 3-1 updates the display data shown on a display screen via a superscribing function. The means 11 holds the contents of the data memory area in the latest form.

Title: Signal reproducing device
Inventor: MORIYA RIYUUSUKE
IPC: G11B20/12
Filed: 1983-03-07
Abstract: PURPOSE:To reproduce faithfully a tape where signals are recorded with a high density by performing accurately the selecting operation of reproduced signals with a selection control signal which is generated on a basis of a block synchronizing signal in reproduced signals. CONSTITUTION:A synchronizing signal B.SYNCn is added to every data block Dn of reproduced signals SA and SB, and a block synchronizing separating circuit 14 separates the signal B.SYNCn. Data designating synchronizing signals B.SYNC0n and B.SYNCEn added to the last blocks D0n and DEn of signals SA and SB is supplied to a block synchronizing detecting circuit 15 from a reference oscillator 16, and the circuit 15 detects these synchronizing signals. A selection control circuit 18 generates a selection control signal SSW on a basis of a delay output signal SDL to control a signal selecting circuit 12. Consequently, a switching position is held correctly to reproduce correctly video signals S0F and SEF continuously even if a variation with time is generated in signals SA and SB. Thus, even the tape where a preamble and a postamble before and after the switching position are shortened to record signals with a high density is reproduced faithfully.

Title: Crank angle sensor and ignition timing control device for internal combustion engine
Inventor: NAGANO MASAMI
IPC: F02P5/04
Filed: 1990-02-19
Abstract: PURPOSE:To surely start an engine even at a low temperature by discriminating signals for fixed advance timing at starting time, set in a plural quantity in cylinders, and selecting the signal from which the predetermined fixed advance timing is obtained in accordance with a cooling water temperature. CONSTITUTION:In the case of a starter switch turned ON, electrification is started synchronously with a predetermined riseup signal when a signal for showing a predetermined cylinder No is set, and the electrification is started by all the riseup signals when the signal for showing the predetermined cylinder NO is not set. When a fixed advance timing signal is not discriminated, electrification to all the coils of a fall down signal is cut off to perform ignition. On the other hand, when the fixed advance timing signal is discriminated, a cooling water temperature is watched to perform ignition by a predetermined fall down signal, when the temperature is in a predetermined value or more, and by a separately predetermined fall down signal when the temperature is less than predetermined value. In this way, starting can be surely performed even at a low temperature.
