Title: Clamp circuit
Inventor: KAWAGUCHI TOSHIHARU
IPC: H04N5/18
Filed: 1988-02-24
Abstract: PURPOSE:To improve the reliability of the circuit by controlling switchingly a voltage set by a reference voltage power supply device synchronously with the ON/OFF of an emitter current, turning on a clamp transistor(TR) at clamp period and applying the on-control to the emitter current. CONSTITUTION:A base potential of a clamp TR 16 is lowered by a value corresponding to the resistance of a resistor R1 for a period other than the clamp period when TRs 19, 20 are turned off in a clamp circuit, since the TR 19 is turned off, the charge in a capacitic 12 is held. In this state, even if a signal with a voltage lower than the DC potential during the clamp period is inputted to an input terminal 11, no effect is caused in the output in a range where the clamp TR 16 is not turned on. Thus, the resistance of the resistor R1 is selected to be a potential difference or over between the DC level and the minimum potential the clamp period of the input signal. Thus, the TR 16 is not turned on for a period except the clamp period and no effect is caused to the output.

Title: Single lens reflex camera
Inventor: NEMOTO KAZUYUKI
IPC: G03B7/20
Filed: 1979-04-06
Abstract: PURPOSE: To prevent the errors of aperture controlling by so arranging the angles of a mounting position defining member, interlocking lever and stopper as to become nearly constant when an aperture ring is in the AE state.  
     CONSTITUTION: When an interchangeable lens 3 is rotated in order to be mounted to the camera body 1 by way of a body mount 2, an aperture ring 7 is first turned together with the lens-barrel body 12 until an interlocking lever 9 contacts a stopper 10. When it does, the turning of the aperture ring 7 is blocked and only the lens- barrel body 12 continues turning up to the specified mounting position. At this time, the aperture ring 7 turns relatively in the clockwise direction with respect to the  lens- barrel body 12 and this results in that the set aperture position moves in the  minimum aperture direction. When the mounting of the lens is completed, the aperture ring 7 is also sufficiently turned with respect to the lens-barrel body 12 and the  AE marks are automatically set at the AE mark positions coinciding with aperture indices 14 irrespective of the initial position of the aperture ring 7.

Title: Dissolved oxygen control in sewage treatment process
Inventor: KATOU NAOJI
IPC: C02F3/12
Filed: 1979-04-09
Abstract: PURPOSE: To keep a constant value of dissolved oxygen content (DO) in an aeration tank by a method wherein the measured results of DO in the tank is used so that when sewage flow rate is reduced, the quantity of air to the tank is decreased below the limit value of surging (vibration of blower and blast tube caused by reduced blow rate of air).  
     CONSTITUTION: Dissolved oxygen meter 7 measures DO and obtains deviation value ΔDO from the target value DO*. The proportion integration regulator 11, in accordance with ΔDO, provides the quantity of air Q*A necessary for compensating for it. The Q*A enters the comparator 14 and is compared with surging limit value QAL. If Q*A is smaller than QAL and therefore surging is likely to occur, relay 15 receives command from the comparator 14 and connect loop of the air-quantity controller 16 from the proportional integration regulator 11, so that air blast valve is controlled. That is, based on the measured air blast quantity QA from the valve opening-degree meter 8, targer valve opening-degree value V*A 1  of flow control valve 5 is calculated and operagion/stop at valve motor 6 is controlled.

Title: Manufacture of damper
Inventor: KINOSHITA SHINYA
IPC: F16F15/22
Filed: 1989-02-22
Abstract: PURPOSE:To prevent an adverse effect being exterted to a damper characteristic after securing a sufficient eccentric preventing effect by sticking a stopper to the peripheral side of a hub by means of vulcanization, and setting a clearance between a mass body and the stopper with retraction after vulcanizing the stopper. CONSTITUTION:When a hub 1 and a mass body 2 are put into a form block and a spring member 3 and a stopper 4 are molded by means of vulcanization, both these members 3, 4 are formed into such a size as touching on an inner circumferential surface of the mass body 2. Then, a bounding agent is applied to this inner circumferential surface of the mass body 2, but this bonding agent is made so as not to be applied to a part coming into contact with the stopper 4. In this state, when the spring member 3 and the stopper are simultaneously vulcanized and formed, a slight clearance 5 made by retraction of the stopper 4 is set in space between the inner circumferential surface of the mass body 2 and an outer end face of the stopper 4. Accordingly, when eccentricity occurs in the mass body 2 with the operation of a damper, the mass body 2 quickly comes into contact with the stopper 4, so that the eccentricity of the mass body 2 can be checked to the smallest possible extent.

Title: Position detecting device
Inventor: AYADA NAOKI
IPC: H01L21/30
Filed: 1984-03-08
Abstract: PURPOSE:To detect a position at a high speed and with a high accuracy by providing a photodetector provided with a space filter-shaped photodetecting surface for making a one-dimensional direction scan light form an image on two objects, and detecting independently reflected lights from the two objects. CONSTITUTION:A relative position relation of a filter and a photodetector is arranged so that a channel stopper 47S of the photodetector makes an angle of 45 deg. against light transmitting parts 45A-45D of the filter. As a result, other light than photodetecting elements 46A-46D is not detected, therefore, the photodetector serves as the filter, too. In case of detecting a reflected light in a stepped part 71, when only a light in the direction 71C is detected without detecting a light in the direction 71A, a light by a prism effect of a resist is not incident on the detector, and the position detecting accuracy is improved. In this way, the light transmitting part of the photodetector serves as the filter, too, therefore, a position can be detected at a high speed and with a high accuracy.
