Title: Exposure control circuit of television camera
Inventor: ARISE FUSAYOSHI
IPC: H04N5/238
Filed: 1979-07-25
Abstract: PURPOSE:To always secure the optimum exposure for picking up the subject, by controlling normally the diaphragm of the TV camera by the mean value of the video signal and then switching automatically to the peak value control when the quantity of light exceeds a certain level. CONSTITUTION:The video signal obtained at image pickup part 2 is amplified 3, and both the mean value and the peak value of the video signal are detected by mean value and peak value detecting circuits 4 and 5 each. The detection signals of circuits 4 and 5 are supplied to control signal switching circuit 7, and the output of circuit 5 is supplied also to peak value comparator 6. Thus the output signal of circuit 5 is compared with the peak value reference potential at circuit 6. And circuit 7 selects the mean value and the peak value in case the peak value of the video signal is lower than the reference potential and vice versa respectively. For this purpose, circuit 7 is controlled by the output of circuit 6. The output of circuit 7 is supplied to operational amplifier 8 to be compared with the reference potential, and this potential difference signal controls diaphragm 1 via diaphragm driving circuit 9. As a result, the video signal of the optimum exposure is obtained at terminal 10 in accordance with the difference of brightness of the subject and the luminous intensity of the subject.

Title: Processing agent dissolving device
Inventor: IKEDA ATSUSHI
IPC: G03D3/06
Filed: 1999-03-31
Abstract: PROBLEM TO BE SOLVED: To eliminate the stationary retention of granular processing agent in a dissolving tank by surely stirring the granular processing agent flowing down to the dissolving tank and dissolving it in aqueous solution. SOLUTION: The so-called chamfering of the respective corner parts of the side wall 104S of the dissolving tank 104 is executed and the chamfering of four corners of the bottom part thereof with respect to a bottom plate 104B is executed besides. Then, the inside circumferential surface thereof is formed by connecting the mutually adjacent walls 104S and connecting the side walls 104S and the plate 104B in a circular-arc state. The plate 104B is conically formed and all ridge lines R are formed to be circular-arc extending over the whole circumference. Thus, since a substance dropping down through the walls 104S and the plate 104B hardly receives resistance (frictional force), it is concentrated at one place of an aperture part by gravity.  The bottom part side of the inside wall of the dissolving tank is formed of a curved surface shaped like the bottom of a ship extending over 1/3 to 1/2 of the height size of the dissolving tank in terms of the size.

Abstract: PROBLEM TO BE SOLVED: To surely send a printing start position of a required paper to a position of a recording head, by arranging a paper detection means at the downstream side of the recording head and detecting both the presence/absence of the paper and a leading end of the paper by the paper detection means. SOLUTION: When a paper is guided at a lower face of a holder 6 by an automatic paper feed apparatus or the like to a paper feed roller 4, a leading end of the paper presses a lever 7b of a paper detection lever 7 up. In consequence, the paper detection lever 7 turns centering a supporting part 7c in the clockwise direction and a switch press face 7a is separated from a switch 14a of a first sensor 14, whereby the switch 14a is turned OFF. The first sensor 14 accordingly detects that the paper is sent to the paper feed roller 4. When the paper is detected, the paper feed roller 4 rotates by a predetermined number of times in a direction of an arrow B. As a result of the rotation of the paper feed roller 4 by the predetermined number of times, the leading end of the paper is transferred to the vicinity of nearly the center below a paper detection means 11.

IPC: H02M3/28
Filed: 1981-06-19
Abstract: PURPOSE:To remove noises generated from a switching circuit excellently by mounting filters at the pre-stage and post-stage of a rectifying circuit. CONSTITUTION:The AC power supply 31 is rectified by the first rectifying circuit 39, the rectifying output is switched by a switching circuit 47, the switching output is rectified by the second rectifying circuit 53 and DC voltage is obtained. The first and second filters 32, 43 are each mounted at the pre-stage and post- stage of the first rectifying circuit 39. Consequently, noises generated in the switching circuit 47 are removed by the second filter 43 first, and further removed by the first filter 32. Accordingly, the efficiency of noise removal by the first filter 43 can be improved because noises emitted to space from wiring between the switching circuit 47 and the first rectifying circuit 39 can be removed by setting up the second filter 43 near the switching circuit 47.

Abstract: PURPOSE:To prevent a misfire positively by setting a diluted air-fuel ratio on the basis of the load of the engine and correcting said ratio in response to the number of revolutions of the engine in the system in which the air-fuel ratio is changed over to a theoretical air-fuel ratio or the dilution air-fuel ratio in response to the state of operation of the engine and controlled. CONSTITUTION:When the engine is operated, the fundamental quantity of fuel injected is calculated on the basis of the quantity of air sucked from an airflow meter 15 in a controller 50. Whether or not the quantity of injection extends over an air-fuel ratio feedback control region is decided on the basis of data such as the temperature of cooling water from a water-temperature sensor 59, and whether or not the quantity of injection satisfies a condition of which the air-fuel ratio can be controlled by the dillution air-fuel ratio is decided when the quantity of injection extends over said region. A fuel injection valve 20 is controlled on the basis of an output from an O2 sensor 60 so that the air-fuel ratio is used as the theoretical air-fuel ratio when the quantity of injectin does not satisfy said condition. When the quantity of injection satisfies said condition, on the other hand, the value of the diluted air-fuel ratio is set on the basis of load value obtained from outputs from the airflow meter 15 and a revolution-number sensor 29, and the air-fuel ratio is controlled according to the value.

Filed: 1978-08-02
Abstract: PURPOSE: To keep a water level in a tank constant by providing a float and a float guide cylinder to a washing tank and controlling the discharge amount of overflowed supply water.  
     CONSTITUTION: When a water level in a washing tank 2a goes down, a float 26a goes down and an opening 24a is opened, then washing water flowing into an overflow tank 23a from a pipe 30a returns to the tank 2a and is not supplied to a previous tank 2b through an overflow pipe 28a. When the water level in the tank 2a rises, the float 26a rises and the opening 24a is closed, then washing water flowing in stays in the overflow tank 23a and is supplied to the previous tank 2b through the overflow pipe 28a. This operation is carried out also between other tanks 2b and 2c. Therefore, the water level in each tank does not become below a predetermined value and the degree of contamination of washing water is always kept constant.
