Title: Synchronizing and separating circuit
Inventor: YAMAMOTO HIDEKI
IPC: H04N5/44
Filed: 1993-09-30
Abstract: PURPOSE:To prevent the delay of synchronous detection at the time of automatic channel selection by varying up the synchronous detection level for automatic channel selection toward the pedestal level from a prescribed level near the synchronizing chip level. CONSTITUTION:Normally, a transistor TR Q2 is turned off to make a detection level control means 4 disconnected, and the synchronous detection level is set to the prescribed level near the synchronizing chip level, and therefore, synchronous detection is surely performed when the synchronizing component of an input video signal Si is small. At the time of channel selection or automatic channel selection of channel preset, the TR Q2 is turned on, and a resistance R6 is connected in parallel to an emitter resistance R2 to reduce the emitter potential of a TR Q1, and the synchronous detection level is varied upward to the correction level of about the pedestal level. Consequently, the synchronizing component is quickly and surely detected even if the DC level of the signal Si is varied at the time of automatic channel selection.

Title: Scan pass circuit
Inventor: OZAKI HIDEHARU
IPC: G01R31/3185
Filed: 1990-10-08
Abstract: PURPOSE:To facilitate timing design of clock signals by contriving a scan-pass circuit in such a way that each flip-flop reads the output at the time before a second clock signal is input into the preceding flip-flop, and outputs it so as to be successively shifted. CONSTITUTION:At the time of a scan-pass test, as a clock signal 10 for the scan-pass test, a clock for operating a shift resister is input. The clock signal 10 becomes the clock signal of a flip-flop 3 via a selector 8. The output of the selector 8 enters the clock terminal C of a flip-flop 2 via a selector 7. The value that the flip-flop 3 reads is the Q output signal 15 of the flip-flop 2 at the time before the clock is input into the flip-flop 2. Since it is not necessary to simultaneously input the clock signals of respective flip-flops, even if there is a clock skew or the like, shift-register operation can be carried out, thus clock-signal design can be facilitated.

Title: Control device for engine
Inventor: FUJIMOTO HIDEFUMI
IPC: F02D43/00
Filed: 1988-10-26
Abstract: PURPOSE:To aim at stabilizing engine output at a speed reducing time and the like from the high speed and load driving of an engine by controlling the engine such that an intake/exhaust air overlap period becomes larger as the speed and load of the engine becomes higher as well as the engine output is made larger at the speed reducing time and the like of an engine. CONSTITUTION:A timing change device 20 is controlled by an overlap control means, so that an intake/exhaust air overlap period is controlled to be large at the high speed and high load time of an engine and small at the low speed and low load time. When the intake/exhaust air overlap period is detected to be large by an overlap detecting means despite an engine is in a small overlap area, an output adjusting means 41 is controlled so as to make the engine output larger by a control means 30. Accordingly, even in case the engine speed is lowered due to the delayed actuation of the timing change device 20 while maintaining the intake/exhaust air overlap period large, the engine can be maintained stable in spite of the backflow of residual gas to an air intake passage.

Filed: 1987-10-28
Abstract: PURPOSE:To predict firing time accurately, by obtaining a period reaching the vicinity of a specified point of the temperature difference characteristic between the maximum temperature of the surface of deposited coal and atmospheric temperature, adding a time period to spontaneous firing, and predicting the firing time. CONSTITUTION:The surface temperature of a coal pile 6, which is deposited and stored on a coal yard 5, is monitored with the infrared-ray camera of a temperature monitoring robot 1. The signal is converted into temperature data with a camera control board 2. The data are imparted into a data process 4 through a signal conversion board 3. Atmospheric temperature data are inputted into the processor 4. The temperature difference between the maximum temperature of the surface of the pile 6 and atmospheric temperature is obtained for every specified period with the processor 4. The fact that the state, in which the temperature difference has a positive value and the deviation from the previous value is within a specified width, is lasted for a specified period is confirmed. When the occurrence of change in temperature difference exceeding the specified width is detected, a time period to the spontaneous firing of the pile 6 from said time point is added. Thus, the firing time is predicted. In this way, the time of the spontaneous firing can be predicted accurately.
