Title: Quadrature amplitude modulation communication system
Inventor: TAKEDA YUKIO
IPC: H04L27/00
Filed: 1986-03-14
Abstract: PURPOSE:To prevent the jitter of recovered carrier by returning a reception state detection signal at the reception side to a sending side via a service channel so as to adjust the injection quantity of a pilot carrier at the sending side. CONSTITUTION:The sending side 100 and the receiving side 200 are attained for 2-way communication by a main channel 301 and a service channel 302, and a main signal subjected to QAM modulation by a modulator 101 of the sending side 100 is demodulated by a demodulator 201 at the reception side 200. Then a reception state detection signal S1 is detected by reception state detector 203 at the reception side 200 and returned to the sending side 100 via the service channel 302. The sending side 100 demodulates the detection signal S1, which is fed to a pilot signal amplitude adjusting device 103 as a reception state supervisory signal S2 to adjust the injecting quantity of the pilot carrier in the modulator 101.

IPC: H01L21/52
Filed: 1992-03-13
Abstract: PURPOSE:To perform accurate bonding with accurate alignment of an optical element even in a vacuum atmosphere which allows excellent bondability. CONSTITUTION:When a forceps 10 which holds an element A is brought down to an element mounting component B, a flange 19 provided on the pincette 10 is brought into contact with the flange 18 of a bellows 15 and the top edge of the bellows 15 is closed. A container 11 is permitted to be airtight, the valve 21a of the gas source is closed and the valve 20a of a vacuum pump 14 is opened so as to sweep the inside of the container 11. The inner space made by the container 11 and the bellows 15 is separated from the outside and the prescribed vacuum degree is allowed. Under such a condition, the flange 19 and the flange 18 of the bellows 15 are tightly attracted to each other. Therefore, even when the forceps is shifted to the front and rear of an element mounting component B or along the element bonding plane of the component B, the airtight condition is maintained by the deformation of the bellows 15.

Title: Control method for photoreceptor surface potential of electronic copying machine
Inventor: TAMURA GIICHI
IPC: G03G21/00
Filed: 1981-04-15
Abstract: PURPOSE:To obtain a certain level of surface potential of a photoreceptor regardless of the mode, by switching the bias voltage applied to the photoreceptor between the normal mode and the automatic original feed mode. CONSTITUTION:In the case of the consecutive copying in the normal mode, a latent image 1a is formed intermittently on the surface of a photoreceptor 1. An undesired image erasing light source 7 is irradiated to the undesired image region between latent images 1a and 1b. In the case of the automatic original feed mode, the automatic original exchanging time A is required. Meanwhile the light source 7 is continuously turned on to erase an undesired latent image 1c in the section A. However, the optical fatigue is caused on the surface of the photoreceptor 1 by the lighting of the source 7. As a result, the surface potential of the photoreceptor 1 increases and decreases as shown by the broken lines to the potential (solid lines) of the normal mode.

IPC: H02N2/00
Filed: 1993-03-16
Abstract: PURPOSE: To attain a technology for the electric drive of a rectifying transducer in the manner that equal mechanical powers are provided at the outputs of non-rectifying transducers. CONSTITUTION: An electric drive system has a controller 40, exciter 42, electric energy storing components 44, a switch 46 and a segmented rectifying transducer.

Title: Manufacture of semiconductor having burying and flattening process
Inventor: MORITA YASUSHI
IPC: H01L27/04
Filed: 1991-02-27
Abstract: PURPOSE:To make it possible to etch back in the substantially ideal conditions, by forming a film having different etching characteristics after burying and performing a flattening in the conditions that deposition slightly progresses on a horizontal surface. CONSTITUTION:A trench corresponding to a space 2 to be buried in a semiconductor substrate 1 is formed and an SiO2 film is formed by a bias ECR-CVD. Subsequently, a film 5 having different etching characteristics is formed and a horizontal return is performed. In this case, the SiO2 film is formed on the horizontal surface as the conditions that an insulator 3 is slightly deposited on the horizontal surface. However, since an etching progress on the slant surface, the film 5 having the different etching characteristics is removed. A horizontal etching progresses by a sputtering etching and then the SiO2 film which is the surplus insulator 3 is removed. Since the film 5 having the different etching characteristics exists above the trench, the film 5 serves as a stopper during SiO2 etching, and proceeding of the etching is prevented, and the film thickness in the space 2 is maintained as it is.

Title: Jitter compensation circuit
Inventor: TAKAMORI TSUTOMU
IPC: H04N9/896
Filed: 1981-04-14
Abstract: PURPOSE:To remove the jitter (variation of time axis) in a color video signal by delaying the color video signal to be supplied to an A/D converter by one horizontal period, and simultaneously delaying the response of a PLL circuit by one- division. CONSTITUTION:A delay circuit 21 delays a color video signal Sc from an input processor 2 and outputs the delayed signal to an A/D converter 3. The PLL circuit 12 consists of a phase comparator 31, a ''0'' division holding circuit 32 holding the compared output from the circuit 31, a VCO33 controlled by the held output, a divider circuit 34 dividing the oscillation output from the VCO33 into 1/N frequency. The divided output from the circuit 34 and the output of a burst gate circuit 11 are supplied to the circuit 31, so that the oscillation output from the VCO33 is made a pulse Pw with the jitter delayed by one horizontal period. Thus, when a digital signal Sd is written in a memory 4, the jitter is removed from the signal.

Title: Fitting and removing device for leverless cassette in copying machine
Inventor: KOIKE TADAO
IPC: G03G15/00
Filed: 1979-05-07
Abstract: PURPOSE: To prevent disorder of copying paper by a method wherein an abrupt movement of the paper-feeding pressure member of a copying machine to the position where the paper-feeding pressure works is controlled by a controlling member acting on the above member.  
     CONSTITUTION: When a cassette is inserted along a cassette guiding plate 25, a projection provided on one side in the front thereof strikes at a pin 16a just before setting. Through the intermediary of the pin, a trigger lever 16 is rotated in the direction of an arrow. Then the engagement of a pin 16b with the tip of a lock lever 18 is released and the lock lever 18 starts rotating in the direction of an arrow under the strong torque of a paper-feeding pressure spring 15. However, the rotation of the lock lever 18 in this direction is conducted, giving, on the other hand, rapid rotation to a fly wheel 21 standing still through the intermediary of a segment gear 18a, a pinion 19 and a coil spring clutch 22, and so the lock lever 18, being controlled by the large force of inertia of the fly wheel 21, rotates slowly. Thus, by being controlled by the force of inertia of the fly wheel, the collision of a pressure shoe with the bottom plate, as well as the disorder of reproduction paper, can be prevented.
