Patent JP-H10207175-A (JP)
Title: Electrophotographic device
Inventor: KATO KOJI
IPC: G03G15/01
Filed: 1997-01-24
Abstract: PROBLEM TO BE SOLVED: To ensure print density, to prevent a peripheral end image while preventing sticking of carrier, and, therefore, to realize high print quality by making the direction of the rotation of the developing roll of a first developing device opposite that of the developing roll of a second developing device. SOLUTION: The peripheral end image relates to the directions of the rotations of the developing rolls 14 and 15. When the direction of the rotation of a photoreceptor 1 is opposite the directions of the rotations of the developing rolls 14 and 15, the peripheral end image conspicuously appears downstream from an image. When the directions of the rotations of the photoreceptor 1 and developing rolls 14 and 15 are the same, the peripheral end image conspicuously appears upstream from the image. Therefore, the developing roll 14 of the first developing device 4 and the photoreceptor 1 are rotated in the same direction, which increases the rubbing force of the developer, thereby causing the peripheral end image only upstream from an electrostatic latent image.  The developing roll 15 of the second developing device 5 is rotated in an opposite direction to the photoreceptor 1, and the peripheral end image occurring upstream from the electrostatic latent image is scraped, thereby obtaining an image free of peripheral end image.

Title: Spectral analyzing device
Inventor: TOUFUKU ISAO
IPC: G01N21/39
Filed: 1982-01-26
Abstract: PURPOSE:To provide a simple structure spectral analyzing device which eliminates division, by a method wherein a lock-in amplifying output is held in a constant manner through negative feedback of the lock-in amplifying output to directly fetch a ratio of a differential collection to a collecting power. CONSTITUTION:Laser light from laser L is collected by a collecting element D through a gas cell GC and is processed by a self-gain adjusting amplifier 4 and lock-in amplifiers LA1 and LA2 to produce a collecting power and differential collecting power. By means of the output of the amplifier LA1, negative feedback of an amplifier 4 is controlled to maintain the amplifier LA1 in a constant output, and an output corresponding to a ratio of the differential collecting  power to the collecting power is fetched directly from the amplifier LA2. This  eliminates a dividing part, which results in forming a simple structure spectral  analyzer.

IPC: H04B1/18
Filed: 1999-01-20
Abstract: PROBLEM TO BE SOLVED: To distribute a high frequency signal without causing deterioration in the noise figure of a tuner. SOLUTION: A high frequency amplifier 1 that receives a high frequency signal from an antenna 8 amplifies the high frequency signal and distributes the amplified signal to 1st, 2nd filters 2, 3 and an RF modulator 7 respectively. A mixer 4 mixes the high frequency signal distributed to the filters 2, 3 with local frequencies to provide an output of an intermediate frequency signal finally. On the other hand, the high frequency signal distributed to the RF modulator, when the RF modulator 7 is inactive, passes through the RF modulator 7 without receiving any modification as an external output.

Abstract: PURPOSE:To enhance refrigerating capacity, by a method wherein an annular groove communicated on one side into an introducing pipe for a refrigerant and on the other side into a discharging pipe for a gaseous refrigerant is provided, a high-pressure refrigerant is passed into the introducing pipe and the annular groove, and a main body of a cylinder is cooled directly by the high-presure liquid refrigerant.

Since the liquid refrigerant thus flowing in is vaporized by the heat generated through compression, the main body 10 is efficiently cooled by the latent heat of vaporization over the wide range from a part proximate to an intake port 17 to a part proximate to a discharging port, whereby the temperature of the refrigerant introduced can be lowered. Accordingly, the input during operation of the compressor can be reduced, and the refrigerating capacity can be enhanced.

Abstract: PURPOSE: To prevent abnormal heating of electric heating means while dissolving bad start of electric motor by providing speed control means for induction motor fan with thermister connected in parallel.  
     CONSTITUTION: A shading coil type electric motor 10 is imposed directly with a voltage in a electric source E and runs at high speed of 2800 rpm when a multiple step switch 26 is thrown into cold and high tap side. On the other hand, when the switch 26 is thrown into low tap side, the shading coil type electric motor 10 is imposed with a voltage reduced about 40% by a voltage reducing resistance 21 and runs at low speed of about 1600 rpm. When the voltage is thus lowered, a starting torque will be reduced because of the lowered revolving speed, however, a bad start of the electric motor will be dissolved and a heating coil  17 will never be heated abnormally because the voltage reducing resistance 21 is connected with a thermister 22 in parallel and full voltage of a electric source E is imposed on the shading coil type electric motor 10 temporarily owing to a high resistance value of the thermister 22 produced by heat of itself.
