Title: Step covering method with insulating film
Inventor: KAMIYAMA MICHIYA
IPC: H01L21/3205
Filed: 1989-07-20
Abstract: PURPOSE:To make it possible to form an insulating film characterized by less inner stress with excellent covering property by once stopping the film forming operation when the insulating film reaches a specified thickness, sputtering the film with cations, removing the specified range of the formed insulating film, and repeating the sputtering every time the specified film thickness is reached. CONSTITUTION:When an insulating film 13 for covering the surface of a steep step part is formed, the film forming operation is once stopped when the insulating film 13 reaches a specified thickness. Sputtering is performed with cations. Thus the formed insulating film is removed to the degree where the upper end surface part of the insulating film 13 is not exposed. Said sputtering step is repeated every time the insulating film 13 reaches a specified thickness. Therefore, a part of the formed insulating film 13 which expands to the upper end corner part of the step part at every sputtering step is removed. A part of the insulating film 13 which is formed in a hill shape between the steps can be also removed. In this way, the surface of a silicon substrate including the step part of each wiring 12 can be covered with the insulating film having the required thickness with excellent covering property. Residual stress for the grown film is less, and the effective insulating film can be formed readily.

IPC: H01J35/12
Filed: 1988-07-29
Abstract: PURPOSE:To improve the reduction in X-ray output accompanied by the material recrystallization by the high temperature of an anode target by diffusing and junctioning a water-proof protecting layer to a target supporting material. CONSTITUTION:An anode target 12 consists of a target supporting material 15, a target layer 16 formed on the whole surface of the target supporting material 15, and a water-proof protecting film 17 formed on the other surface. As the target supporting material 15, a highly anticorrosive material having a high heat conductivity, for example, silver, is used. The target layer 16 is formed by diffusing and junctioning a material emitting a desired characteristic X-ray, for example, a thin plate of copper, iron and molybdenum, and the water- proof protecting film 17 is formed by diffusing and junctioning, for example, a thin plate of gold. Thus, this water-proof protecting film 17 does not have a defect such as hole and is minute. Hence, the reduction in X-ray output by the material recrystallization accompanied by the high temperature of the anode target 12 can be improved.

Title: Deep drawing method of anisotropic blank material
Inventor: MORI MASAHIKO
IPC: B21B3/00
Filed: 1983-10-11
Abstract: PURPOSE:To obtain a product having no strain by rolling preliminarily a blank material in the direction orthogonal with the rolling direction when said material is rolled to a flat plate shape to make the material isotropic then subjecting the material to deep drawing. CONSTITUTION:A blank material used for deep drawing, for example, a flat titanium plate 3 is formed by hot rolling an ingot 1 only in one direction A and is made into a blank material having anisotropy. The plate 3 having anisotropy is then cut to a prescribed length if necessary and is rolled in the direction B orthogonal with the rolling direction A by a hot rolling mill 2. The titanium blank plate 3' subjected to the pretreatment in the above-mentioned way is subjected to deep drawing by a punch and die in the same way as in the prior art. The warpage occurring in anisotropy is thus eliminated and the blank material is thoroughly worked.

Title: Pressure change absorbing device
Inventor: NUKUI KAZUMITSU
IPC: F16L55/04
Filed: 1995-06-30
Abstract: PURPOSE: To reduce a bad influence to up/down action of a float due to sticking of a mist in gas. CONSTITUTION: A float 220 is received in a case 210, to perform vertically moving in accordance with a differential pressure between the upstream and the downstream. When the differential pressure is a fixed value or less, the float 220 is not floated, to cut off a discharge port 212 of the case 210. By increasing the differential pressure, gas flows in from the upstream through an introducing port 211, to press up the float 220 and to flow out in the downstream by partly opening the discharge port 212. The discharge port 212 acts as a kind of throttle mechanism, absorbs fluctuation of pressure in the upstream, and suppresses transmission to the downstream.  Since a sufficient space is provided between a peripheral surface of the float 220 and an internal peripheral surface of the case 210, even when here is stuck a considerable amount of mist in gas, a bad influence is prevented from being given to vertically moving the float 220. Since the float 220, while guided by three guiding protrusive parts 214 or the like, performs vertically moving, stable action without rolling can be performed.

Abstract: PURPOSE:To obtain a battery holder which can prevent wrong installation of a coin-shaped battery in an apparatus main body. CONSTITUTION:The battery housing 21 of a battery holder 20 has an inner diameter to allow to house a battery 1. And the peripheral edge of the bottom 22 of the battery housing 21 is formed in a circular arc almost the same as the chamber dimension R at the negative electrode 2 side of the battery 1, and a hole 23 is also formed. Furthermore, the width of the upper surface of the battery housing 21 and the width at the lowermost end of the bottom are formed at the size almost equal to the thickness of the battery 1. When the battery 1 is housed normally in the battery housing 2, the battery 1 can be housed closely therein. But, when the battery 1 is housed with its polarity reversed, the corner at the positive electrode 3 side not chamfered hits the circular arc of the peripheral edge of the bottom 22, the upper side of the battery 1 is made in the condition projecting from the upper surface of the battery housing 21, and the battery holder 20 cannot be inserted to the insertion hole 32 of the maing body 30 of an apparatus. The wrong installation of the battery can thus be prevented.

Title: Adaptive equalizer for analogue optical signal transmission
Inventor: MAAKU HANAA
IPC: H04B10/516
Filed: 1995-07-25
Abstract: PROBLEM TO BE SOLVED: To automatically equalize an intermodulation distortion product obtained as a result of nonlinear modulation response of a laser by providing an adaptive equalizer which generates a corrected electric signal having a frequency as high as that of a higher harmonic distortion product. SOLUTION: An adaptive equalizer 112 converts an electric data signal 110 as the electric representation of a transmit data signal 104 into an electric modulated signal 114 and transfers it to the laser 116. Namely, the equalizer 112 detects the phase and amplitude of the higher-harmonic distortion product and shifts the phase of the corrected electric signal according to the detected phase so that the corrected electric signal and higher-harmonic distortion product conjugately match each other. Further, the adaptive equalizer 112 amplifies the phase-shifted corrected electric signal and higher-harmonic distortion product so that their amplitudes become equal to each other. Then the corrected electric signal which has been amplified and shifted in phase is coupled with the electric data signal to generate the electric modulated signal 114.

Abstract: PURPOSE:To charge without damaging a storage battery and without performing a troublesome operation by detecting that a radio telephone set is fitted to a connecting device, making a rapid charge only to make up for the quantity of consumed electricity and switching it to a standard charge after that. CONSTITUTION:When a radio telephone set 4 is fitted in a connecting position 2, a detecting means 28 detects it and informs a control circuit 22.

A control circuit 22 starts the rapid charge by the output of the detecting means 28 and switches it to the standard charge when the time set by the rapid charge adjusting means 29 passes. Thus, the charge can be made without damaging the storage battery 41 and without performing the troublesome operation.
