Title: Method of modifying fine surface
Inventor: KUGIMIYA KOUICHI
IPC: C23C16/48
Filed: 1984-05-08
Abstract: PURPOSE:To realize a surface modifier having excellent abrasion resistance and improved fitting strength, by applying charged beams and modifying gas onto the surface of a material to be modified in a vacuum so as to grow a modified layer anisotropically. CONSTITUTION:A material to be modified 11 is held at a low temperature in a vacuum chamber with the rear face or the like grounded. A coating material 12 is deposited thereon and a minute aperture is formed in a desired place. Modifying gas 14 and charged beams 15 are applied so as to be concentrated in the aperture 13. Consequently, reaction and diffusion are proceeded even at a low temperature by excitation by the charged beams 15 so that a modified layer 16 is formed. Further, since the excitation is caused along the direction in which the charged beams 15 are applied, the reaction is caused anisotropically, that is, the reaction is caused exclusively in the longitudinal direction but little in the transverse direction. When this method is applied to a semiconductor device, a high density of about 1mum can be realized since a bird's beak does not project by more than 0.3-0.5mum.

Abstract: PURPOSE:To reduce an area, to shorten a distance between contacts to submicron size of 1mum or less in a self-alignment manner and to realize the increase of density and speed by using poly Si for leading out an electrode. CONSTITUTION:In a bipolar Tr, poly Si 15 for leading out an emitter electrode and poly Si 15' for leading out a base electrode are separated in submicron size of 1mum or less, and oxide films 16 are formed only between the poly Si 15 for leading out the emitter electrode and the poly Si 15' for leading out the base electrode and on the poly Si 15' for leading out the base electrode, and are not shaped on the poly Si 15 for leading out the emitter electrode. Accordingly, since an emitter region and a base-contact are isolated by the oxide films of 1mum or less, an inactive base region is made extremely smaller than conventional devices, thus largely reducing the area of a base only by a section corresponding to the remarkably decrease of the inactive base region.

Abstract: PURPOSE:To improve the control accuracy for sheet shapes and to facilitate roll changing by installing slide bearing pads and plural pushing means in the inlet and outlet sides of work rolls and controlling horizontal and vertical directions of the work rolls by pushing respective bearing pads. CONSTITUTION:Slide bearing pads 16-19 are installed in the inlet and outlet sides of work rolls 20, 21 and cylinder rods 12-15 as a pushing means are installed in plural, respectively.

A horizontal displacement of the rolls 20, 21 is correctly controlled because the rolls 20, 21 are pushed from the inlet and outlet sides by the pads 16-19 or segmented bearings. Therefore, the control accuracy for sheet shapes is improved and roll changing is facilitated by simplification of peripheral devices around the rolls.

Title: Human body detector
Inventor: FUKUDA MASAHIKO
IPC: G01J5/34
Filed: 1993-04-20
Abstract: PURPOSE:To detect a position where a human body exists using a single infrared detector. CONSTITUTION:Effective detection areas 2A-2C having different areas are set in partial detection areas 1A-1C by a condensing unit. When a human body traverses the effective detection areas 2A-2C, far infrared radiation from the human body is detected by an infrared detector. Output from the infrared detector has different frequencies for the effective detection areas 2A-2C. Consequently the existence of human body in any one of the partial detection areas 1A-1C can be detected based on the variation time or frequency of the output.

By repeating the flow of cold water as just described above, cold water is accumulated in tank 2-1-2-4. The accumulated cold water is supplied to an air conditioner acting as a secondary heat exchanger 7 with a secondary pump 6 by being sucked up through a secondary circuit pipe 9 from the lower layer opening part 11 of the tank 2-1 at the air conditioning operation during the day. When space is heated in winter season, the opening and closing of opening parts at upper layer 10 and of those at lower layer 11 are reversed.

Title: Junction of semiconductor wafers
Inventor: SHINPO MASARU
IPC: H01L21/18
Filed: 1984-05-10
Abstract: PURPOSE:To easily attain rigid junction of semiconductor wafers having large areas by finishing the surface of two sheets of semiconductor wafers like the mirror-surface, placing the ground surfaces of them in the close contact under a reduced pressure, placing them again under the atmospheric pressure and executing the heat processing at a particular temperature. CONSTITUTION:It is desirable that the surface roughness of ground surfaces is set to 500Angstrom  or less and after the grinding the surfaces are washed sufficiently, the surfaces are dried up and placed in close contact within a chamber under the reduced pressure. When a pressure within the chamber of reduced pressure is set to 10mTorr or less, good contactness can be attained because residual gas such as air can substantially be disregarded. The heat processing under the atmospheric pressure brings about effective increase in injuction strength of wafers when temperature is 200 deg.C or hither. Particularly, the heat processing at a temperature of about 1,000 deg.C is desirable in order to attain good electrical characteristics. When temperature rises upto 1,300 deg.C or higher, deformation of wafer such as creep is generated as in the case of conventional hot-press method. If a foreign matter such as dust is adhered to the bonding surface, good junction body cannot be obtained. Therefore, purification of ambient is very important for the processes from washing of wafer to junction.

IPC: H01L21/60
Filed: 1997-04-11
Abstract: PROBLEM TO BE SOLVED: To prevent generation of cracks in a package body or a bonding part with a board by providing a fine strip non-bonding part which lowers bonding property of a package body to an upper surface of a chip-type board so that one end thereof faces an outer circumferential part of an IC chip and the other end faces an outer circumferential part of a package body.

Title: Fuel return amount computation method of common rail type fuel injection device, actual fuel injection amount computation method, and fuel injection control method
Inventor: ODA TOMIHISA
IPC: F02D41/04
Filed: 1998-04-06
Abstract: PROBLEM TO BE SOLVED: To restrain scattering of fuel injection amount in each cylinder. SOLUTION: When no fuel injection is made from each fuel injection valve 1 and no fuel supply is made from a fuel pump 5 to a common rail 3, based on variation in the pressure of common rail, the static return fuel amount flowing out from the common rail normally irrespective of the fuel infection operation of the valve 1 is computed. Then, according to the variation in the pressure of common rail at the time when the fuel injection operation is made so that no actual fuel injection may be caused in the valve 1, the dynamic return fuel amount being the fuel amount leaking following the fuel injection operation of valve 1 is computed.  At the time of actual fuel injection, the total amount of the actual fuel injection amount and the return amount is calculated from the common rail pressure variation before and after the fuel injection then each return amount is subtracted from the total amount, and thereby the actual fuel injection amount is obtained. Scattering of fuel injection in each cylinder can be restrained by compensating a fuel injection command value so that the actual fuel injection amount may correspond with a target fuel injection amount.

Filed: 1990-04-09
Abstract: PURPOSE:To realize such a smooth motion characteristic that an acceleration curve has no dip part by using a nonstationary simple harmonic curve as the motion characteristic of a body to be tested. CONSTITUTION:When a DC motor rotates to rotate a cam 4, a lever 7 swings around a fulcrum shaft 8 along a cam curve as shown by arrows (a) and (b).

Further, this acceleration sensor is held on an air slider, so the sensor is put in smooth motion with small vibration.
