Title: Image forming device and its manufacture
Inventor: OGURA MASAAKI
IPC: H01J9/44
Filed: 1998-05-01
Abstract: PROBLEM TO BE SOLVED: To promote desoprtion of the residual gas molecules and to reduce the gas release by electron collision by emitting electrons from an electron emitting part while applying a negative voltage to an anode part formed on a substrate during exhausting of an image display device. SOLUTION: The residual gas in a vessel is discharged through an exhaust pipe 109 while heating the envelop of an image forming device. A getter also degasses by external induction heating. To the ground voltage corresponding to a driving XY matrix wiring within a rear plate 100, a minus voltage is applied to an anode part 104 while evacuating an airtight vessel. A pulse voltage is also added to the element electrode of a surface electron emitting element 102 to drive it. A gas molecule 132 adsorbed near the element is repelled by an electron 135, partially forming a plasma ion 131, which is then accelerated by the minus voltage applied to the anode part 104 and collided to a phosphor 105 and the anode part 104. Further, the residual adsorbed gas is descerped from the collision part, and the pressure in the image forming device is increased.

Title: Super precision machine tool
Inventor: SAWADA KIYOSHI
IPC: B23Q11/14
Filed: 1987-05-21
Abstract: PURPOSE:To eliminate almost completely the effect of heat produced by a motor by covering a motor with an outer shroud of a heat insulation material allowing an exhaust space communicating to outside between the motor periphery and a case, and arranging a motor shaft with a gap with respect to a supporting portion and the heat insulator. CONSTITUTION:Air in an air pocket 20 is drawn out to an exhaust space 18 as jet air from a nozzle 23 passing through a jet hole 22 produces venturi effect. By the depression at this time, air around a motor shaft 25 is sucked up through a communication clearance 24 so that the air is positively moved and exhausted outside. Air in the exhaust space 18 is released rapidly to the outside by the pressure of the jet air.

Title: Multipoint measuring instrument
Inventor: YUHARA HITOSHI
IPC: G08C19/30
Filed: 1988-05-19
Abstract: PURPOSE:To simply change a channel to be recorded or displayed by dividing respective input signals into plural groups, outputting an inherent control signal in each group and discriminating the control signal. CONSTITUTION:In case of detecting the ON/OFF of external contacts C1-Cn, a switch SW is turned on similarly to the detection of the disconnection of thermocouplers T1-Tm to allow a fine current to flow into a scanner 2 and to detect the size of voltage impressed to respective input terminals of a comparator 15. Namely, when the external contacts are closed, the voltage of an amplifier 3 is lower than VC, but when the external contacts are opened, the voltage of the input signal line of the amplifier 3 goes higher than the VC. Thereby, the on/off of the external contacts C1-Cn can be detected from the polarity of the output signal outputted from the comparator 15. An operation control part 11 detects the on/off of the external contacts C1-Cn and controls a recording part 7 so that a channel belonging to a group corresponding to each external contact can be recorded.

Title: Liquid crystal panel and its production
Inventor: OGURA SHIGEKI
IPC: G02F1/1339
Filed: 1993-05-26
Abstract: PURPOSE:To more easily form the state of embedding a sealing material into the spacing between substrates in such a manner that a liquid crystal does not intrude into the spacing between the substrates on the outer side of the region to be encapsulated with the liquid crystal. CONSTITUTION:The sealing material 16 for sticking the liquid crystal panel substrates 12, 14 is provided with a light shielding film 22 over the entire periphery thereof. This light shielding film 22 extends to the side opposite to the part 16b across a parting line 20 from the part 16a on the outer periphery of the sealing material near the part 16b along the substrate 12 before hardening of the part 16b on the inner periphery of the sealing material. Then, the inner peripheral part 16b is cured while the outer peripheral part 16a is held uncured by irradiating the sealing material 16 with UV rays via the light shielding film 22 from the substrate 12 side. The substrate 12 is parted by the parting line 20 after curing of the inner peripheral part 16b. Since the outer peripheral part 16a is held uncured, the parting is easy. In addition, the outer peripheral part 16b fills the spacing between the substrates of the parting line 20 and the part near this line and, therefore, purposes are achieved. The uncured outer peripheral part 16a is cured after the parting of the substrate.

Title: Product sum computing element

IPC: G06F7/527
Filed: 1997-05-14
Abstract: PROBLEM TO BE SOLVED: To execute multiplication correction at a high speed with simple circuit constitution in a product sum computing element used for the operation of graphic data. SOLUTION: At the time of executing the operation of A×αwith the variable A of eight bits and the variable α of eight bits, which is mathematically set to be '1' when all bits are '1', the variable A is added to A×α as a correction item for correctly making an operation result to be 0×FF, and A×α+A is operated. Since the variable A can be set as the correction item 3 from the beginning of calculation, partial products 4, 5, 6 and 7 are added to the correction item 3 without waiting for the multiplication result of A×α. Thus, the operation can be processed at a high speed. Since the variable A itself is used as the correction item 3, the operation is realized with a simple circuit.

Title: Manufacture of mesa-type semiconductor device
Inventor: TANAKA YOSHIMI
IPC: H01L21/56
Filed: 1978-10-06
Abstract: PURPOSE: To accomplish highly accurate opening of holes and forming of electrodes by preventing the swell of a glass film over an insnlating film of a substrate in forming the glass films on the mesa grooves of the substrate by the eletro-cataphoresis method.  
     CONSTITUTION: A p-layer 7 is placed on an n-type Si substrate 1 and an n-layer 8 is formed. Thus, a pn junction which is practically in parallel with the main surface of the substrate is constituted. Then, electrode openings are made through an SiO 2  film 9 that covers the substrate 1, and mesa grooves 11 are provided by a resist mask 10. Furthermore, glass films 12 are formed on the mesa grooves by the electrocataphoresis method without removing the mask 10. After the treatment of several minutes at about 900°C and sintering of the glass films, portions of the glass films shrink and retreat to the portion of the glass films that are located inside the mesa grooves, as the mask 10 is burned and disappeared. Since rise-up of the glass films over the film 9 is very small, poor contact of an electrode-forming resist mask and poor contact of a light illumination mask are eliminated, thereby the openigs for electrodes 13 and 14 are formed quite accurately.

Title: Semiconductor light emitting element
Inventor: YOSHIDA TOMOHIKO
IPC: H01S5/00
Filed: 1992-05-15
Abstract: PURPOSE:To provide a semiconductor light emitting element wherein light emission inside a region whose wavelength is shorter than green can be acquired, a strain is not generated between a substrate and a semiconductor layer thereon and light can be oscillated with high efficiency. CONSTITUTION:Layers 3, 4 which consist of a II-VI compound semiconductor are formed on a III-V compound semiconductor substrate 1 and a layer 5 consisting of a III-V compound semiconductor whose lattice constant is almost the same as that of the substrate 1 is laminated and formed thereon. The II-V compound semiconductor can oscillate light in a region whose wavelength is shorter than a green region in mixed crystal ratio which enables lattice matching to a substrate. Furthermore, since the III-V compound semiconductor layer 5 has a small contact resistance with an electrode 6 which is metal, a current is easy to be injected into an element. Therefore, light whose wavelength is shorter than green can be oscillated with high efficiency.
