Abstract: PURPOSE:To stabilize the performance of the combustion controller by a construction wherein the output of a photodetector for detecting burning flames of fuel like gas etc. is introduced into a differentiation circuit including a shift register and the shift register is driven by high clock signals for iginition and by low clock signals for the subsequence. CONSTITUTION:When a photodetector (not shown by a figure) detects a flame, an FL signal on the H level is outputted and inputted into a differentiation circuit 2-2 through an AND gate 3-2. Therefore, when the FL signal takes an L level, the input of a shift register 2-2a of the differentiation circuit 2-2 takes an L level and a quick clock signal CLK1 is introduced from the front step of a dividing circuit 7-1 through an AND gate 2-2c, an OR gate 2-2e. If a signal takes an H level by firing, the output of the shift register 2-2a takes an H level and a slow clock signal CLK2 is introduced through an AND gate 2-2d, an OR gate 2-2e. Thus, operations are stabilized by changing response speeds for firing, extinction.

Title: Flowrate control device of actuating fluid for power steering
Inventor: HONAGA SUSUMU
IPC: B62D6/00
Filed: 1983-10-11
Abstract: PURPOSE:To obtain a stable operation without a sense of incompatibility by suppressing a flowrate increase using a control diaphragm that determines the spool valve speed when load pressure is generated while the number of pump rotations is increasing and the flowrate sent to a power steering device is decreasing. CONSTITUTION:The exhaust oil of a pump driven by an engine reaches the first valve chamber 18 of a flowrate control device from a feed path 15 and is fed to a power steering device through a diaphragm path 28 and a forwarding port 12. Then, when exhaust flowrate is increased as the number of pump rotations is increased, a spool valve 17 moves left so as to make the pressure difference in front of and at the rear of the diaphragm path 28 and a bypass path 16 is slowly opened and then an excessive flow is exhausted. Subsequently, the diaphragm path 28 narrowed by the large diameter section 27B of a control rod 27 and the pressure oil supply flowrate is reduced. When load pressure is generated, the spool valve 17 moves right because the valve chamber 18 and a second valve chamber 19 are connected through diaphragm devices 36, 38, and 39 whose diaphragm degree differs according to the flow direction.

Abstract: PURPOSE:To contrive to improve the operability and to prolong the life of an input pen by using a pen supported by a support member so that the pen can swing and an amplifier which is filled with liquid. CONSTITUTION:The tip of the pen 3 of the input pen is brought into slanting contact with the detection surface 12 of a tablet and then the pen 3 swings to draw the lower end surface 56 of the amplifier 5 downward. Consequently, a bellows part 51 expands to increase the capacity of a large-diameter cylinder 53, and the liquid in the amplifier 5 moves to the cylinder 53 to make a bellows part 54 on the side of a small-diameter cylinder 53, so that the movement quantity of an output surface 57 is increased as compared with the movement quantity of an input surface 56. A magnet 8 fixed to the output surface 57 of the amplifier 5, therefore, moves toward the pen 3 and electromotive force generated by the variation of magnetic flux penetrating a coil 10 is applied as a command signal (timing signal for coordinate detection) to a coordinate detecting device. When the input pen is made to leave the tablet detection surface 12, the support member 2 restores itself by its elasticity and to restore the bellows part 54 and shrink the bellows part 51.

IPC: H04N5/378
Filed: 1987-07-30
Abstract: PURPOSE:To prevent the flicker of an image from occurring by controlling a charge accumulating time to an image pick-up element according to the frequency of an external light. CONSTITUTION:The titled device has a sensor 11B to detect the external light and frequency detecting circuits 17 and 18 to detect the frequency of the external light from the output of the sensor 11B, and based on the output of the frequency detecting circuits 17 and 18, the accumulating time of a charge to an image pick-up element 3 is controlled. Namely, for example, when an image pick-up system is an NTSC system and an external light frequency is 50Hz, respective charge accumulating times are into 1/100 sec equal to a light quantity changing period. When the image pick-up system is a PAL system and the external light frequency is 60Hz, respective charge accumulating times are made into 1/120 sec equal to the light quantity changing period. In such a way, when the field frequency of the image pick-up system and the external frequency are different, since, for example, the respective charge accumulating times are made to be equal to the light quantity changing period, the integration value of the light quantity of respective charge accumulating times are made to be equal, and the flicker generation of the image can be prevented.
