Title: Display control device
Inventor: CHIBA TOSHIKAZU
IPC: G09G5/00
Filed: 1988-01-29
Abstract: PURPOSE:To cause the generation of the internal data transferring cycle of a DRAM to be necessarily minimum by providing a flag register to determine whether the output of a second circuit goes to be effective only when the output of a third circuit is active or the output of the second circuit is effective regardless of the output of the third circuit. CONSTITUTION:A first circuit 101 detects a display cycle, with which a BLK (blanking signal) 1 is inactive and all addresses of an m bit go to be '0', and outputs the signal of a DT (over-bar) 2. A second circuit 102 detects the head display address cycle of each horizontal display line based on the BLK 1. A third circuit 103 outputs a signal to show a first one horizontal scanning period based on a vertical blanking signal VBLK and a horizontal synchronizing signal HS. It is determined by a flag register 105 whether the output signal of the second circuit 102 is masked by an output signal FS of the third circuit 103 or not. Thus, the generation of the internal data transferring cycle DT (over-bar) of the line buffer building-in DRAM can be caused to be necessarily minimum.

Title: Stabilizing method for interval of oscillation frequency of laser device
Inventor: SHIMOZAKA NAOKI
IPC: H01S5/068
Filed: 1988-01-29
Abstract: PURPOSE:To enable a desired control to be performed for a controlled laser device as well which has a large modulation index and is modulated with an FSK, by a method wherein after only a low frequency component is selected from a beat signal, the envelope thereof is differentiated and then subjected to a half-wave rectification to form two pulses, and subsequently one pulse of the two pulses which are obtained in one of a plurality of laser devices is made a component of a beat pulse train. CONSTITUTION:From a double-humped beat pulse corresponding to an FSK modulated light, only the rear hump part is selected. Next, the resultant pulse is applied to a circuit a whose output is to be sent to a counter. In this connection, in the circuit (a), the pulse is differentiated through a differentiation circuit and subsequently converted into two pulses by a diode. Thereafter, these two pulses are shaped into two square waves each of which has the amplitude equal to a logical level through both a Schmitt trigger circuit and a NOT logic element. Further, the former pulse is eliminated through both a T.FF and an OR circuit in the next stage, but the latter pulse is inputted to a counter in the following next stage. Thus, by the operation of the circuit (a), the double-humped beat pulse corresponding to the spectrum of the RSK modulated light is converted into a single pulse which rises at the time corresponding to the center frequency of a modulated wave. As a result, the interval of an oscillation frequency can be stabilized for the FSK modulated light.

Title: Suction device of internal combustion engine
Inventor: HATA YOSHITAKA
IPC: F02D9/02
Filed: 1981-02-17
Abstract: PURPOSE:To make it possible to improve combustibility by opening only a primary suction passage in a driving range where the quantity of sucked air is small and arranging its blow-off port in the vicinity of the combustion chamber, in the internal combustion engine in which the fuel in the quantity corresponding to the quantity of sucked air is injected. CONSTITUTION:In the driving range where the quantity of sucked air is small, when only a primary throttle valve 16 is opened, the sucked air which has passed through the throttle valve 16 is blown off from branch parts 19A, respectively. As the blown-off air having a large flow rate is mixed with the fuel injected from an injector 20, the blown-off air is introduced into the combustion chamber 21 along the inner wall in the form of a spiral air current. Accordingly, the fuel is promoted of its atomization and mixed sufficiently with air. Further, upon transient driving of the engine, since the capacitance of the primary suction passage is smaller as compared with the capacitance of the entire part, the detected value obtained by a suction air flow quantity sensor becomes close to the actual suction air quantity. Thus, the control of the fuel injection quantity can be properly performed.
