IPC: H01L21/3065
Filed: 1988-08-16
Abstract: PURPOSE:To execute an etching operation uniformly, to easily attach and detach a gate valve during its cleaning operation and to enhance an operation rate by a method wherein the gate valve is constituted of the following: a valve body used to close an opening part between a reaction chamber and a spare chamber so as to set the opening part on the same face as an inner wall face of the reaction chamber; a drive source used to drive the valve body in an oblique direction. CONSTITUTION:A gate valve 19 constituted of the following is installed at the lower part of a frog leg 18 used to convey an object to be treated: a triangular pyramid-shaped valve body 19a used to close an opening part 17 between a reaction chamber 11 and a spare chamber 16 so as to set the opening part on the same face as an inner wall face of the reaction chamber 11; two cylinders 19b used to drive the valve body 19a in an oblique direction. Thereby, the opening part 17 can be sealed from the oblique direction by using the gate valve 19; a structure can be simplified sharply; it is possible to prevent a leak to be caused when a product generated by an etching operation adheres. Accordingly, a cleaning cycle can be made long; an operation rate of an apparatus can be enhanced sharply. In addition, since a recessed part is not produced at the opening part 17 between the reaction chamber 11 and the spare chamber 16, an electric discharge is not concentrated and the object to be treated can be etched uniformly.

Title: Ccd video camera system
Inventor: FUJII TATSUYA
IPC: H04N5/378
Filed: 1993-08-18
Abstract: PURPOSE:To economically provide a video camera system having performance corresponding to a case when a non-defective CCD pickup element is used and the number of effective picture elements larger than a conventional system through the use of the CCD image pickup element where defective picture elements exist. CONSTITUTION:A picture element position comparison part 7 detects the defective picture elements in the CCD image pickup element 1 since the visual importance of the individual picture elements is small in a high definition picture. A mean value calculation part 12 executes interpolation by the mean value of the signal values of the proximate picture elements. A selector 14 substitutes the resultant value for the signal value of the defective picture element to obtain the picture of satisfactory quality. Manufacturing cost is reduced, a problem that yield is made low when achieving no defect is solved and the number of the valid picture elements is increased by using CCD image pickup element 1 where the defective picture elements exist. A programmable logic circuit is used in the picture element position comparison part 7 detecting the defective picture elements so as to the number and the positions of the defective picture elements different from the respective elements. Thus, correspondence can be executed with single hardware.

Title: Frequency synthesizer, multi-modulus frequency divider and charge pump circuit
Inventor: NAVIDD FOLDI
IPC: H03L7/089
Filed: 1999-07-16
Abstract: PROBLEM TO BE SOLVED: To obtain the PLL frequency synthesizer whose power consumption can be saved by giving a frequency control signal to an oscillation means so as to change a frequency of an output signal thereby phase-locking the output signal with a reference signal. SOLUTION: A reference signal Sr with a frequency fr is fed to the programmable dual-modulus frequency divider(PDMD)131 whose output signal Srd with a frequency frd is given to a phase/frequency detector(PFD)133. The (PFD)133 receives a signal Sod from other PDMD135. The (PFD) 133 detects a phase difference and a frequency difference between signals from PDMDs 131, 135 and provides pulse trains F, S. The charge pump(CP) circuit 137 in response to the pulse trains F, S generates a source current or a sink current Icp. A loop filter 139 converts the current Icp into a voltage Vc and this voltage Vc controls a frequency generated by a VCO 141 that provides an output signal So of the PLL frequency synthesizer.

Title: Linear motor
Inventor: MATSUMOTO GIICHI
IPC: H02K41/02
Filed: 1990-07-31
Abstract: PURPOSE:To get a guide rail for linear motor, which can be cut without lowering the life by filling up a resin layer at the specified position in the inner space of the guide rail so that cutting chips may not scatter inside the guide rail when cutting the guide rail. CONSTITUTION:Resin is blown and filled up in the inner space at the position, at which one wants to cut the guide rail 1, by spray method through the guide groove 1a so as to form a resin layer which blockades the inner space of the guide rail 1. This resin is quick-dry type, and in the dry condition, it is jelly- form and forms a highly viscous layer. In case that one wants to cut the guide rail 1 in required length, since a highly viscous resin layer 6 is formed to blockade the inner space at the cutting position, if one cuts the approximately center position of the resin layer 6 with an iron saw, or the like, the cutting chips do not penetrate into the inside over the resin layer 6, where the needle block moves, so the cutting work can be performed without lowering life.

Title: Driving method for electro-optical element
Inventor: SUGIYAMA ATSUSHI
IPC: G02F1/133
Filed: 1987-08-17
Abstract: PURPOSE:To shorten the erasion time and to improve the practicability, by executing an erasion by impressing both a pulse voltage and a voltage of about zero volt. CONSTITUTION:The electro-optical element is constituted by preparing a panel of an HTN system of 400X640 pixels, setting a tilt angle of a liquid crystal at 25 deg. by an oblique vapor-deposition of a silicon oxide as an orientation processing, and setting a twist angle of the liquid crystal at 270 deg., and thickness of a cell to 6mum. In this panel the thing which is added with chiral dopant is enclosed. When an erasion pulse voltage Ve of the same degree as write is applied by + or -13 volts at one millisecond of erasion pulse width Pe in an erasion period, an erasion time (te) is shortened, and even by the erasion time of 25 milliseconds, the panel can be driven. Also, as for the panel which is added by the chiral dopant just a little to the liquid crystal, the element which is not erased completely more than several minutes, even if an electric field is eliminated after write can be made. In such a way, the erasion time can be shortened.

Title: Fuel injection quantity control device for internal combustion engine
Inventor: AKIYAMA TADASHI
IPC: F02M55/00
Filed: 1994-08-29
Abstract: PURPOSE: To simplify an air bleeding mechanism when there is a spot in a fuel passage where no fuel is present and to reduce a cost. CONSTITUTION: A fuel sensor 45 is located in a fuel pipe 22 communicated with an injector 19. During normal operation, a central processing unit(CPU) regulates an amount of fuel injected from an injector 19 so that an air-fuel ratio is adjusted to a stoichiometric air-fuel ratio. In the starting of an engine 1, it is decided by the CPU whether fuel is present in the vicinity of a fuel sensor 45 and when fuel is present, it is decided that air is present in a fuel pipe 22 and the injector 19 is forcibly opened for control. Thereby, air is pushed by fuel without arranging a piping for an exclusive use and an electromagnetic check valve and exhausted through the injector 19 under opening. Further, when air is sufficiently discharged, switching to normal opening control, and the injector 19 is prevented from being left opened.

Title: Curved tube type fluorescent lamp
Inventor: ITOU HIDENORI
IPC: H01J61/32
Filed: 1983-10-31
Abstract: PURPOSE:To eliminate the need for a special shaped exhaust tube and make mounting parts common in the opposed both ends and bending section of a luminous tube by bending and molding both ends toward the diametrical outside of an annular section that is bent annularly. CONSTITUTION:Both ends 12 and 12 and bending section 17 that are close to each other and opposed are bent toward the diametrical outside of the respective annular sections 18 and 18. Therefore, both the ends 12 and 12 and the bending section 17 are almost in parallel on the same level as a plane containing the annular sections 18 and 18. As a result, since the sealing end face of both the ends 12 and 12 and the bending section 17 are not opposed to each other, an exhasut pipe 19 need not be bent just in front of the bending section 17 as before. Besides, the special shaped exhaust pipe 19 is not required and the common use of mount 13 parts is enabled and then cost reduction can be achieved.
