Title: Vane pump
Inventor: KUMOSHITA KOUHEI
IPC: B01F25/60
Filed: 1980-07-07
Abstract: PURPOSE: To discharge two kinds of fluids in an arbitrary mixing ratio or distribute them with an arbitrarily divided pressure distribution ratio by independently communicating each of four (4) ports provided in two pairs of suction and discharge areas with each of four (4) piping openings provided for a pump body.  
     CONSTITUTION: When a rotor 1 is rotated counterclockwise, vane 4 are rotated, as they are projected by a centrifugal force so that their ends contact with a cam surface of a cam ring 3. A fluid I from a suction inlet A enters a pump chamber through a suction part A'. Then, between (b) and (c) in a discharge area, it passes through a discharge port B' and is discharged from a discharge outlet B. And a fluid II from a suction inlet C enters the pump chamber through a suction port C', while it is discharged from a discharge outlet D passing through a discharge port D' between (d) and (a) in the discharge area. The volume of each pump chamber in said suction and discharge areas varies by diversifying the eccentricity (e) of the  cam ring 3.

Title: Sensitivity correction method for image reading device
Inventor: HIROMATSU KENJI
IPC: H04N1/19
Filed: 1995-03-24
Abstract: PURPOSE: To produce the white reference data without having the influences of such defects as dust, soil, scratches, caused on the surface of a white refer ence plate by reading an output signal of an image reading device in a state where nothing exists at a white reference position. CONSTITUTION: The output signal of a CCD 112 is read out under a condition where no shield exists on an optical path that reaches the CCD 112 from a light source 106 via a return mirror 108. This read output signal is used as a white reference data, and a shading of the image data is corrected based on the reference data. As a result, the white reference data can be produced in a simple constitution and without using a white reference plate. Thus it is possible to completely correct the dispersion of sensitivity characteristics of the CCD 112 and to easily read out the images with high accuracy.

Title: Apparatus and method for x-ray lithography
Inventor: JIEEMUSU EMU FUOOSAISU
IPC: H01S3/23
Filed: 1987-04-14
Abstract: An x-ray lithography system is disclosed in which x-rays (56) are generated by directing a high energy laser beam against a metal target (26) to form an x-ray emitting plasma. The x-rays from the plasma are then directed through a mask towards a resist covered wafer (58) to cause a patterned exposure on the wafer resist coating. The mask, the portion of the target which the laser beam strikes and the portion of the wafer to be exposed are all within an evacuated chamber (22). The laser, prior to entering the chamber,is split into two separate beams (24, 24A), each of which are focused and directed through a window (70, 72) in the side of the chamber towards the same spot on the target. Apparatus, including an air bearing, seal and positioner, is provided to move the target at periodic intervals. Similar apparatus is provided to move the wafer from exposure section to exposure section. The laser beam system includes a face pumped laser beam amplifier (188) and unidirectional beam expanders (232, 280) to allow the maximum energy to be transferred to the laser beam by the amplifier. A series of two or more laser pulses are provided in order to maximize the energy obtained from the laser amplifier. A magnet (76) and a membrane (77) shield are also provided to prevent high energy particles and dust contaminants from the plasma from effecting the lithography process. A materials handling device (14) is provided for moving wafers, targets and masks and an alignment system operating within the evacuated chamber, positions of the wafer with respect to the mask prior to the exposure thereof.

Title: Radio communication equipment
Inventor: KEIRINBOU HISASHI
IPC: H04B7/26
Filed: 1996-04-15
Abstract: PROBLEM TO BE SOLVED: To avoid deterioration in quality of data transmission and useless increase in traffic by conducting data transmission only when a state of a communication channel is excellent. SOLUTION: An idle signal from a base station C is received by a radio section 11, a MODEM section 12, a CODEC section 13 of a mobile radio equipment T, based on it a CPU 16 detects a reception electric field strength level and an error rate to discriminate a state of a channel. Only when the state of the channel is excellent, data stored in a RAM 15 are modulated and the modulated data are sent from the radio section 11. Thus, the data are sent by taking deterioration in quality of a radio channel due to multi-path or fading or the like into account, then the transmission quality is enhanced and the traffic efficiency is improved.

Abstract: PURPOSE: To prevent deformations such as crease and torsion from arising on an elastic unit and reticulate unit by releasing the roller in elastic bubble unit which has been inserted in the flexible reticulate unit as kept focedly in a tubular insertion guide from the said insertion guide.  
     CONSTITUTION: After forcing a roller 6 in elastic bubble unit into an insertion guide 10 with a pressurizing means 12, a burr preventing means 13 is pulled out of the roller 6. Next, the guide 10 is covered on its outer perimeter with a flexible reticulate unit 9, allowing its end to project somewhat from bottom of the guide 10. After that the roller 6 in elastic bubble unit is protruded at a stroke from the guide 10 in the direction indicated by arrow. A compressive force to which the elastic bubble unit has been subjected is released to allow it to come closely in contact with inner perimeter surface of the reticulate unit 9. No slippage will result between both the two nor crease, flapping, torsion, burr, etc. will take place on perimeter of the roller 6, thus covering the reticulate unit 9 uniformly.

Title: Picture operation device
Inventor: KOSHIDA NOBUYOSHI
IPC: G06E1/00
Filed: 1991-03-30
Abstract: PURPOSE:To simplify a system by constituting the system of an optical informa tion input medium, plural point light sources for information operation, and a screen on which the read operation result is displayed. CONSTITUTION:Input light having an energy larger than the band gap of an optical semiconductor, for example, N2 laser light is equally divided into two by total reflection mirrors 3 and 4 and is reflected by total reflection mirrors 1 and 2 and is allowed to pass masks A and B of an input pattern and is made incident on both faces of a two-layered optical (de)intercalation cell. When a voltage is applied to a second transparent electrode by a controller at this time so that a first transparent electrode has a positive potential, optical intercalation (coloring) does not occur, and therefore, encoding can be performed simultaneously with storage of the input pattern. This information is subjected to picture operation by flickering of plural point light sources arranged in the front, and the operation result is nondestructively read out onto the screen arranged at the rear.
