Title: Powder capsule
Inventor: IWAMURA RIYOUJI
IPC: B22F3/04
Filed: 1983-03-04
Abstract: PURPOSE:To prevent the generation of a crack and to detach easily a powder capsule from the powder molding in the powder capsule to be used for cold hydrostatic molding by providing a thin walled part and a thick walled part thereto along the longitudinal direction to produce a step and using rubber as the material of the capsule. CONSTITUTION:A hydrostatic pressure is loaded over the entire region on the outside circumference of a powder capsule 1A which is packed internally with powder, is hermetically closed in the aperture thereof with a plug and is long in one direction, thereby forming a powder molding. A thin walled part 1a and a thick walled part 1b are provided to the capsule 1A along the longitudinal direction thereof to produce a step in the wall thickness in the longitudinal direction and capsule is made of rubber. The tensile force acting on the powder molding in the stage of releasing the pressure is thus decreased, by which the generation of a crack is prevented and the capsule is easily detached from the powder molding.

Abstract: PURPOSE:To improve the reliability of a transfer data by selecting an absolute value data at a period specified by a selecting means and transferring it so as to confirm a basic data of the arithmetic operation based on a difference in each unit. CONSTITUTION:When a transmission request is given to a control unit 121, a data stored in a RAM 16 is sent to a transmission line 11 and received by other control units 122-12n. When the transmission request exists in an initial state, the absolute value of the transmission data is sent, stored in the RAM of the control unit, and the absolute value data is stored also in the control unit 121 at the transmission side simultaneously In the next transmission request, the absolute value of the data to be sent this time and that of the preceding data stored in the RAM 16 are compared to calculate the relative value of a changing part. Then the data corresponding to the relative value is sent to the transmission line 11. The control units 122-12n use the relative value data and the preceding data to calculate the absolute value of the data this time and it is stored as a new data and used for the control.

IPC: C02F1/62
Filed: 1982-03-03
Abstract: PURPOSE:To enhance adsorbing capacity of a heavy metal adsorbent prepared by adding and depositing a reaction product of polyethylene imine and carbon disulfide to activated carbon, to mercury to a large extent, by adjusting an adding and depositing ratio of the heavy metal adsorbent to activated carbon within a specific range. CONSTITUTION:Activated carbon is treated with polyethylene imine with M.W. of 600-6,000 and carbon disulfide in the presence of water and a reaction product of polyethylene imine and carbon disulfide is added to and deposited on the activated carbon to prepare a heavy metal adsorbent.

Title: Laser interferometric length measuring apparatus and its measuring error correction method
Inventor: FUKUTOMI KOJI
IPC: G01B9/02
Filed: 1994-03-04
Abstract: PURPOSE:To reduce the influence of a temperature by a method wherein an optical material in which a coefficient of thermal expansion and a refractive-index temperature coefficient are respectively positive and negative or negative and positive is used for a light-transmitting optical element through which reference light and measuring light are transmitted. CONSTITUTION:A laser beam from a light source 1 is separated by a beam splitter 2, separated beams are reflected respectively by a moving mirror 40 and a fixed mirror 50, the beams are superposed again by the splitter 2, and an interference is generated. Then, temperature changes from the initial state of the moving mirror 40 and of the fixed mirror 50 are designated respectively as DELTATm and DELTATf, the optical path length of the laser beams which are transmitted through both is designated both as L, and the coefficient of linear expansion, the refractive index and the refractive index temperature coefficient of both are designated respectively as alpha, (n), beta. Then, a change DELTAX in a length measured value due to a change in the optical path length L due to a temperature is expressed as DELTAX=L{alpha(n-1)+beta} (DELTATm-DELTATf)/2. Consequently, when DELTATm=DELTATf, the length-measured value is not changed. When they are not equal, the positive sign and the negative sign of the alpha and the beta are mutually reversed, and the alphaand the beta are offset. As a result, a length measuring error can be suppressed to be small.

IPC: B21H8/00
Filed: 1994-02-09
Abstract: PURPOSE:To equalize the height of threaded knots and also to prevent deviation in a rolling direction by arranging a rolling equipment in which a caliber with a specific necking is formed and thereby performing advance rolling for necking parts only. CONSTITUTION:In order to roll a deformed bar with threaded knots, rolling is performed for forming a base bar material 31 with an elliptical cross-section; and then, while a necking is formed in its center, rolling is performed to make a cross section in the shape of the figure 8. The base bar material 11 with the cross section in the shape of the figure 8 is rolled from the circular cross section side by a pair of rolling rolls for forming threads. Then, in the rear side of the rolling mills 7, 8 for forming the elliptical cross-section, undriven rolls 17, 18 are arranged in which a caliber is formed in such profile that the radiused shape part of the draw-down is the same as or less than the necking in the rolling for the cross-section in the shape of the figure 8, that the depth of the necking is not more than 80% of the whole height, and that the remainder is nearly the same as the base bar material 11 with the elliptical cross-section; and the only the necking part is rolled in advance. Consequently, the deviation is reduced for the two threaded knots oppositely facing.

Abstract: PROBLEM TO BE SOLVED: To proivde a semiconductor integrate circuit device, and its manufacturing method, wherein degradation in characteristics resulting from dispersion of emitter resistance is eliminated while increase in the number of manufacturing processes is suppressed. SOLUTION: A part of a silicon 16 for forming the electrode of a transistor is left alone on a silicon 10A where a resistance element is formed, which is to be a protective film 16A. When the silicon of an emitter electrode 18 of transistor is silicified, a part of resistance region on the surface of resistance element 10A is prevented from being solidified by the protective film 16a, thus high resistance is assured. Since the protective film 16A is formed in the same mask process as the emitter electrode 18, the number of mask processes is not increased.
