Abstract: PURPOSE:To enable to obtain the output voltage which is stable regardless of the input voltage and load, by providing a Triac, trigger circuit driving Triac, time constant circuit, reference control voltage generating circuit, feedback circuit and breeder resistances. CONSTITUTION:The input voltage from the terminal IN is applied to one end of the bidirectional switch SBS of the trigger circuit via the filter circuit 1, reference control voltage generating circuit 2, and time constant circuit 3, and a voltage dividing the input voltage with resistances R4, R5 is applied to another end of SBS with the feedback circuit 6. The output of the circuit 4 is inputted to the gate terminal of the Triac T via the capacitor C4. A voltage is applied to SBS according to the amplitude of the input voltage, and the conduction angle of the Triac T is greater when the input voltage is lower and smaller when the input voltage is higher. Control is made so that the variance of the input voltage can be cancelled. A fixed effective voltage is supplied to the output terminal OUT. Further, abnormally high voltage at no load can be prevented with the breeder resistance R7 connected in parallel with the terminal OUT.

Title: Backlash eliminating device for zoom finder device
Inventor: OGAWA YUJI
IPC: G02B7/10
Filed: 1996-02-20
Abstract: PROBLEM TO BE SOLVED: To provide a backlash eliminating device preventing the backlash of a cam member from causing the inadvertent movement of a movable variable magnification lens. SOLUTION: When a zoom photographing lens moves from a housing position to a zoom photographing position, a follower protrusion 19P enters the gradient cam section R2 of a cylindrical cam 19C from the flat section R1 of it. Force in a direction orthogonal to an optical axis is not applied to the cylindrical cam in a state where the follower protrusion 19P abuts on the flat section R1, and when it abuts on the gradient cam section R2, the force in the direction orthogonal to the optical axis is applied to the cylindrical cam, so that the backlash is eliminated by turning the cylindrical cam, and the movable variable magnification lens does not move because the follower protrusions 23P and 24P are in contact with shifting sections 23C and 24C.  When it enters a zoom section Z, a light emission block and the movable variable magnification lens follow the cylindrical cams 19C, 23C and 24C and move in the direction of the optical axis.

Title: Photochromic adhesive composition and adhesive sheet
Inventor: KAWASHIMA TADASHI
IPC: C09J201/00
Filed: 1996-02-21
Abstract: PROBLEM TO BE SOLVED: To provide an adhesive compsn. which can visualize an adhesive and prevent the color of the adhesive from being viewed through an adherend and retains excellent stability even after the elapse of time by using a rubbery resin reduced in moisture absorption as a main component of an adhesive and a photochromic dye as a colorant. SOLUTION: This compsn. comprises at least an adhesive material and a colorant, wherein the adhesive material is composed mainly of a rubbery resin reduced in moisture absorption and the colorant is a photochromic dye. Use of a photochromic dye as the colorant permits the adhesive compsn. to absorb light in the ultraviolet region from sunlight or a room lamp and to emit a color, thereby visualizing the adhesive, and facilitates bonding work. Incorporation of the above rubbery resin as a main component into the adhesive material can prevent fading caused by contact of the photochromic dye with water. Addition of a tackifier to the adhesive compsn. can enhance the adhesive strength.

Title: Signal detecting circuit
Inventor: SENSUI ASAMI
IPC: H04B10/2507
Filed: 1982-03-01
Abstract: PURPOSE:To prevent the operation due to a noise signal at a non-signal period and to detect signals accurately, by setting the circuit so as not to be operated at a signal being a noise level signal or below. CONSTITUTION:When a photo signal P is inputted via a photo detection diode 1, an electric signal in response to an amount of light is amplified through an amplifier 2. This amplified signal is sliced via a comparator 3, changed into a binary signal and applied to a gate circuit 8. In this case, the output of the amplifier 2 is amplified via an amplifier 4 and inputted to a comparator 7 through a diode 6. Since the comparator 7 slices a signal at a point C at the level of noise signal or below, the output goes to 1 and a circuit 8 is opened. Thus, when the signal is inputted, the detection signal from the comparator 3 is outputted as it is. Further, at non-signal, the comparator 7 detects the noise signal as the noise component at the non-signal period and the circuit 8 is set to an inoperative state.

IPC: G01R5/16
Filed: 1981-03-11
Abstract: PURPOSE:To make it possible to return an indicator of a meter to zero position quickly when the power source is turned OFF and also to minimize capacity of a capacitor in a backup circuit, by providing a zero-reset discharging circuit which is designed to operate when the power source is turned OFF. CONSTITUTION:A signal put into an input terminal 2 is converted to an analog voltage by a converter main body 1, smoothened by a smoothing circuit 3, converted to a meter driving signal by a driving circuit 7 and outputted to a meter 8. An indicator of the meter 8 indicates a value in accordance with the aforementioned driving signal. Under this state, such a load is accumulated in a capacitor 6 in the circuit 3 that voltages on the both terminals become equal to the aforementioned analog voltage. And then, when a switch 12 is opened, the capacitor 6 starts discharging through resistors 5 and 14. For this reason, voltage being put into the driving circuit 7 decreass rapidly, the driving signal of the meter 8 also decreases and the indicator of the meter 8 returns to zero quickly. Since a value of the resistor 14 is selected such that the indicator returns rapidly, it is possible to minimize capacity of a capacitor 10 in a backup circuit 9.

Title: Turbine movable blade
Inventor: KANEKO JIYOUJI
IPC: F01D5/12
Filed: 1978-03-24
Abstract: PURPOSE: To prevent the generation of cracks due to excess stress by applying to stress corresponding to the force in the direction of returning the blade twist due to revolution, as an initial stress, and combining each blade.  
     CONSTITUTION: When the most suitable form of blade determined from heat design, fluid design, strength design, and so on is adopted as regular shape, the twist return amount 5 due to the centrifugal force generated in the free state operation of the blades which are not connected with shrouds and tie-wires is obtained, and the blade shape for working having correction portion 6 in the direction of increasing twist is determined, and the blades are fixed on the vane-wheel by a fixing part 7. The twist increasing amount due to the correction part is compulsorily warped to form a regular shape condition, and each blade is connected with tie-wires or shrouds 3. As a result of this, the force in the dirdection of return of twist generated through revolution is offset, and the deformation compensates regular shape in revolution as a whole.
