Title: Latch-up preventing power circuit
Inventor: TANAKA HIROSHI
IPC: H03K19/003
Filed: 1994-12-16
Abstract: PURPOSE: To provide a latch-up preventing power circuit which performs the control so as not to exceed the latch-up generating voltage level when a power supply is applied with use of a different power supply that has already risen and then generates the voltage having the difference from the power voltage lower than the latch-up generating voltage level. CONSTITUTION: In a latch-up preventing power circuit which generates the voltage of 4.6V from a 5V power supply, a 12V power supply that rises earlier than the 5V power supply is connected to an output terminal via a transistor TR Q3. Thus a current can be supplied from the 12V power supply when the 5V power supply rises. When the 5V power supply is applied, the TR Q3 is first turned on and a current flows from the 12V power supply. When the time passes and the 5V power supply rises up to a voltage level where a TR Q1 can operate, the TR Q1 is turned on and a current is supplied from the 5V power supply. As a result, the output voltage of the latch-up preventing power circuit rises in response to the rise of voltage of the 5V power supply. Thus a latch-up state can be prevented when a power supply rises.

Abstract: PURPOSE:To efficiently produce oscillating laser light whose phases are put in order by providing a reflecting mirror on output reflecting members so as to put the effective light passage length of laser light which passes an effective light point at which near sightedness field image of semiconductor laser is formed. CONSTITUTION:An output reflecting member 12 has a reflecting mirror 12C so that the effective light passage lengths from each effective light point is put in order each other on the effective light points at which a near-sightedness field image is formed.

Therefore, laser light which is passed on each effective light point performs oscillation operation in a prescribed phase corresponding to mutually arranged effective light passage lengths and the oscillating laser light LA1 whose phases are put in order in a lateral mode can be produced.

Title: Instrument and method for measuring particle size distribution
Inventor: KODAMA ATSUSHI
IPC: G03G9/087
Filed: 1989-12-01
Abstract: PURPOSE:To measure the particle size distribution of toner in a two-component developer right after development by providing a permanent magnet which attracts magnetic powder in a sample to be measured in front of where the sample to be measured is spouted. CONSTITUTION:The two-component developer which is supplied from a sample charging part 1 to a groove for sample conveyance formed on a rotary table 2 is carried in a guide-in part 5. An excessive developer is scraped by a scraper 3 during the conveyance and leveled by a roller 4.

Intense permanent magnets 8 are installed on both sides of the flow passage 7 and carriers are attracted to the internal wall of the flow passage 7 with the magnetic force of the magnets. The toner after being attracted is sent in a measurement part 9 by compressed air. The laser light from a laser light source 10 causes Fraunhofer diffraction with toner at the measurement part 9 and the image is formed on a detector 12 where a diffraction ring is positioned on the focal plane through a condenser lens 12. This diffracted image is analyzed by a computer to obtain the particle size distribution.

Title: Spring device
Inventor: IWATA MORIMASA
IPC: F16K31/70
Filed: 1992-10-28
Abstract: PURPOSE:To provide a spring device as an actuator of a simple and small-sized constitution at a low cost by combining a pair of magnets capable of relatively moving in the approaching or separating direction by magnetically attractive or repulsive force with a coil spring made of a shape memory alloy which overcomes resilient force according to the magnitude of a transformation temperature. CONSTITUTION:When a temperature of cooling water inside an inlet passage (b) is low, a temperature of a compression coil spring 6 made of a shape memory alloy soaked in the cooling water is also low. Accordingly, magnetic attraction force between a movable and a fixed permanent magnets 1, overcomes resilient force of the compression coil spring 6 so that the movable permanent magnet 1 can be held in a valve closing position. As a result, a valve port 3 of a communicating hole 2 is closed at the inner circumferential surface of the inlet passage (b), thus inhibiting the cooling water from flowing in an outlet passage (c). When a temperature of the cooling water becomes high and a temperature of the compression coil spring 6 reaches a transformation temperature, the shape of the compression coil spring 6 returns to a memory shape. Consequently, the resilient force becomes larger than the magnetic attraction force between the permanent magnets 1, 4. As a result, the movable permanent magnet 1 is moved in a valve opening position so as to open the valve port 3.

Title: Planetary roller type power transmission
Inventor: NAITOU KIYAO
IPC: F16H13/08
Filed: 1995-12-01
Abstract: PROBLEM TO BE SOLVED: To machine a fixed wheel with high accuracy using a relatively simple method. SOLUTION: This device includes a fixed shaft, a sun shaft, a plurality of planetary rollers interposed between them while being pressed into contact with them, and a carrier on which each planetary roller 4 is freely rotationally supported. A straight cylindrical surface 12 shorter than the effective track width of the planetary roller is formed in the axial middle region of the inner peripheral surface of the fixed wheel, and round parts 13, 13 are formed at both ends of the inner peripheral surface, with only the cylindrical surface 12 polished while the round parts 13, 13 are unpolished. In this case, since the round parts 13, 13 at both ends can be machined after determination of the region of the cylindrical surface 12 based on the effective track width, the axial width W1 of the cylindrical surface 12 is not varied by machining of the round parts 13, 13.

Title: Method for controlling placement of product for cartoning machine
Inventor: AZUMA ATSUO
IPC: B65B5/04
Filed: 1992-10-28
Abstract: PURPOSE:To cause no empty carton to be produced by providing a commodity detecting sensor and a carton detecting sensor at positions for placing commodities wherein even if an error in making a box occurs, this is eliminated to prevent a shift in synchronization with product placement from occurring. CONSTITUTION:Cartons are sequentially carried on a carton making conveyer 3 by intermittent feeding, and the cartons are prepared for commodity insertion while they move to a commodity placement position A. A commodity carrying conveyer 2 is also driven at the same time, so that the is carried to the commodity placement position A. Even when either a commodity or a carton first reaches the position A, an insertion pusher 10 may not operate, but when a commodity detecting sensor 21 detects the commodity and a carton detecting sensor 20 detects the carton, the insertion pusher 10 is operated. Then after the commodity is inserted, both conveyers 2, 3 are moved by one pitch. When the commodity does not reaches the position A with or without the carton at the position A, the conveyer 2 is driven until the commodity reaches. Or when no carton exists at the position A, the conveyer 3 is driven until it reaches.

Title: Piezoelectric oscillation gyro and driving circuit therefor
Inventor: KURODA TATSUYA
IPC: G01C19/56
Filed: 1994-11-24
Abstract: PURPOSE: To provide an oscillation gyro having high detection sensitivity which can follow well the variation of rotational angular speed without decreasing the dimensions of an oscillator and a driving circuit therefor. CONSTITUTION: Oscillation circuits 32, 33 apply AC voltages of reverse phase to piezoelectric elements 14, 24, 16, 26 to cause secondary bending oscillation in an oscillator 12. When a gyro begins to rotate in that state, a Coriolis force acts on the oscillator 12 depending on the angular speed thereof to vary the oscillating direction thereof. Consequently, the impedances of piezoelectric elements 18, 20, 28, 30 are varied and detected, while being combined, by means of a differential amplifier circuit 34. Since the secondary bending oscillation of the oscillator 12 has a frequency higher than that of primary oscillation, the response is enhanced in the detection of angular speed.
