Title: Output circuit
Inventor: MATSUI HIROSUKE
IPC: H03F3/45
Filed: 1988-03-02
Abstract: PURPOSE:To reduce the current consumption of the entire circuit by giving a current amplified by common emitter 1st and 2nd transistors(TR) with a large current amplification factor to an output stage comprising 1st and 2nd current mirror circuits. CONSTITUTION:A large output amplitude and current output capability is obtained by giving a current amplified by the common emitter 1st and 2nd TRs 27, 28 with a large current amplification factor of several tens to several hundreds to an output stage comprising the 1st and 2nd current mirror circuits 3, 6. Then the base input current of the common emitter 1st and 2nd TRs 27, 28 is decreased with no signal applied. Thus, the current consumption of the entire circuit is reduced. Moreover, the circuit is operative by a voltage being a sum of the collector-emitter saturation voltage of TRs 10, 11 of a differential amplifier 15 and a base-emitter voltage of a TR of the current mirror circuit connecting to the output of the differential amplifier 15 and then the circuit is driven by a low power supply voltage.

Title: Removaing method and apparatus of cohesive developer
Inventor: NAKAMURA TOSHIHARU
IPC: G03G13/09
Filed: 1978-04-27
Abstract: PURPOSE: To prevent the inconvenience occuring in the cohered toner with a simple constitution by letting the cohered toner concentrate in the strong magnetic field formed on a non-magnetic sleeve and removing the cohered toner among the toner used for developing.  
     CONSTITUTION: The magnetic lines of force of the same direction strike against with each other owing to the repulsion action of the same poles N1, N2 provided in proximity to a part of a magnet 6 and the region B of a high magnetic flux density exists in the space part slightly above between the two poles. The magnetic material in the magnetic field receives force from the position of a lower magnetic flux density toward the position of a higher magnetic flux density. Hence, large force acts upon the cohered toner of large particle diameters containing many magnetic materials therein and the cohered toner concentrates in the region B. Thereupon, if the magnet is so disposed that the same poles Ni, N2 come right under the magnet, then the cohered toner 8 having concentrated falls by gravity and may therefore cohered toner 8 be removed automatically by the simple constitution.

Abstract: PURPOSE: To enhance an O 3  decomposition rate by injecting O 3  from a plurality of O 3  injectors provided in a pass for exhaust gas contg. a malodorant such as H 2 S or NH 3  so that the ratio of the residual malodorant and O 3  is made constant at O 3 injection points.  
     CONSTITUTION: O 3  is injected into exhaust gas 4 contg. H 2 S as a malodorant from line 3 1  in the ratio of O 3 :H 2 S=3:1, and gas 4 passes through O 3  contact vessel 1 while decomposing part of the H 2 S. Fresh O 3  is then injected from line 3 2  so taht the ratio of the residual malodorant and (the residual O 3 +fresh O 3 ) is made constant (1:3). Thus, the malodorant H 2 S is further decomposed. Fresh O 3  is finally injected into the exhaust gas passing through vessel 1 from line 3 3  under the same condition as that of line 3 2  to decompose most of the malodorant, and the deodorized exhaust gas is drawn out of the system through line 5. The O 3  decomposition rate of this method reaches 87.5% by injecting O 3  to H 2 S in a ratio of 3.45:1.

Title: Vibration displacement detector
Inventor: BAN KOSHIN
IPC: G01H11/06
Filed: 1996-03-08
Abstract: PROBLEM TO BE SOLVED: To allow vibration displacement to be measured highly accurately without need for calibration or adjustment on each object to be measured by connecting a detector coil which stretches according to displacement of a metallic body for varying self inductance to the metallic body which displaces in contact with the vibrating object. SOLUTION: When high-frequency current is supplied from an oscillator 3E to a spring-like detector coil 5, eddy current occurs on a coil 5 side of a metallic body 7 by high-frequency magnetic flux generated from the coil 5. Vibration of an object 10 to be measured is transmitted to the coil 5 via the metallic body 7 and an insulator 6. Thus, a distance between the metallic body 7 and the coil 5 varies, and also a change occurs in a diameter of the coil 5 and the number of coil windings (winding density) per unit length due to stretching of the coil 5, so that this change in shape appears as a change in self impedance of the coil 5. Then, a converter 3 uses a Wheatstone bridge circuit 3A or the like to detect a change in self inductance, thereby detecting vibration displacement of the object 10 for outputting.

Abstract: PURPOSE:To enable a tape cassette to be ejected even when a power source is cut off, by constituting a device so that it is not operated even depressing an ejection button when the button is energized, and the tape cassette can be ejected manually by engaging the ejection button with a manual ejecting mechanism when the button is deenergized. CONSTITUTION:While the power is supplied, a plunger 1 is put in a state that it is attracted, and a plunger lever 2 engaged with the plunger 1, is made turn in a counterclockwise direction. An ejection button 3b is also made turn in the counterclockwise direction by the turning of the plunger lever 2, and a relation between the plunger lever 2 and the ejection button 3b goes to a state as shown in broken line in figure. At such a time, when an ejection button 3a is depressed in arrow head direction, the ejection button 3b is not engaged with an ejection arm 5, passing through the side of the arm because the button is positioned shown in broken line. The depression of the ejection button 3a is detected by an electrical circuit, and the ejection arm 5 is made turn in a clockwise direction by an electrical ejecting mechanism. In the state where the power is cut off, the plunger 1 is not attracted, and the plunger lever 2 is not made turn, and therefore, the ejection arm 5 is made turn when the ejection button 3a is depressed, then manual ejection can be performed.

Title: Color discriminating photoelectric switch
Inventor: YAMASHITA SHIGEAKI
IPC: G01J3/51
Filed: 1981-04-06
Abstract: PURPOSE:To make it possible to discriminate colors highly accurately, by limiting the amount of transmitted light by using interference filters, thereby obtaining the outputs of the photoelectric elements corresponding to tristimulus values of spectrum. CONSTITUTION:White light emitted from a light projector 31 is diffused and reflected by the surface of a detecting body 32. The diffused reflected light 33 which has a specific spectral energy distribution based on th colors of the body 32 is condensed by a lens 34 and inputted to the interference filters 35-37 as the parallel light. The filters 35-37 are constituted by a metallic film 51 and an intermediate layer 52. If the film thickness (d) of the intermediate layer 52 changes, the central wavelength lambda. changes. The ares of an aperture part 53 of shielding plates 38-40 is the area corresponding to the tristimulus values of the spectrum, and the amount of the light passing the shielding plate is limited. Thus the spectral energy distributions for the decomposed elements of the tristimulus values of the spectrum are obtained. Therefore the tristimulus values of the spectrum are obtained as the outputs of the photoelectric elements 41-43. The outputs are given to a computing circuit 47, chromaticity coordinates X and Y are obtained, and an output switching circuit can be operated.
