Title: Method for casting refractory material under reduced pressure and vibration
Inventor: SASAKI TOSHIHISA
IPC: B28B1/26
Filed: 1994-02-25
Abstract: PURPOSE:To release a compounded state resulting from kneading and deaerate the compound without lowering a flowability by a method wherein a compound of a refractory material is deaerated through a vibrating screen while the refractory compound is allowed to fall to be cast. CONSTITUTION:A preliminarily prepared refractory compound is loaded in a hopper 8. After a pressure reduction tank 11 is sealed by an upper cover 9 and a door 12, a pressure in the pressure reduction tank 11 is reduced to 0.5 atmospheric pressure or lower by sucking air through a suction pipe 10, and a valve 14 is closed. A screen 6 is vibrated at a frequency of 300-2000/min by turning ON a switch of a vibrating machine 13. A casting form 1 is vibrated by driving a vibrating machine 2. After that, a damper 7 is opened, and the compound in the hopper 8 is made to fall on the screen 6. The falling compound rolls on the screen 6 by being vibrated by the vibrating machine 13, thereby being diffused and finely dispersed through meshes to be charged in the form 1. At this time, the compound is finely cut by the meshes of the screen 6, thereby being acceleratedly deaerated.

Title: Core for motor
Inventor: IMAI TAKESHIGE
IPC: H02K29/00
Filed: 1985-02-16
Abstract: PURPOSE:To obtain a core for a motor which does not generate an eddy current even when an alternating current is flowed by bundling magnetic conductive wires and securing the bundle with securing means such as a binder. CONSTITUTION:Magnetic conductive fiber 11 made of an amorphous or soft iron is molded and secured in a rod shape with a binder. In this case, the fiber 11 and the binder are mixed at a ratio of 90-95% to 5-10% by weight, and the diameter of the fiber 11 is 20-100mum. Then, when the rod-shaped material 13 obtained in this manner is cut by a rotary grindstone cutter 12 at every desired length, cores 14 are produced. Thus, even if an alternating current is flowed to the coil, it can prevent an eddy current from generating to enhance only the magnetic flux density of the coil.

Title: Illuminated seesaw switch
Inventor: TSUNEMATSU MASAO
IPC: H01H9/18
Filed: 1996-02-16
Abstract: PROBLEM TO BE SOLVED: To surely prevent light leak from the surrounding of a pushing key operating part with the occupied space to a front plate reduced by using a pushing key formed by projecting a pair of elastic pieces in the rear, and regulating the position of the tip of the elastic piece with a light conductor. SOLUTION: When an operator pushes one end of an operating part 2, a pushing key 1 bends elastic pieces 9, 10, and rotates on a swinging fulcrum part 4. When the operating force is removed, the key 1 automatically returns to the original position by the restoring force of the elastic pieces 9, 10. For example, when the right end (left end) of the operating part 2 is pushed, the elastic piece 9 (10) elastically coming into contact with the side surface 16a (16b) of an engaging part 16 is bent so as to be pressed against the side surface 16a (16b), and a switch element 12 (13) corresponding to an actuator 7 (8) is driven. A light source 14 is assembled on the inside of a light conductor 15, and light is conducted to the operating part 2 through the light conductor 15.  Since the positions of the elastic pieces 9, 10 are regulated with the engaging part formed in the light conductor 15, setting of a position regulating member is made unnecessary, and the undesirable downward extension of the elastic pieces 9, 10 is also made unnecessary.

Title: Manufacture of liquid charged cylindrical vibration damper bushing
Inventor: FUJINAMI KYOICHI
IPC: F16F13/14
Filed: 1991-01-30
Abstract: PURPOSE:To provide an method of producing a liquid charged cylindrical vibration damper bushing which has an excellent durability. CONSTITUTION:An elliptic cylindrical inter ring 2 is jointed thereto with a vibration damper rubber member 3 extending ion its major axis direction thereof. Further, wall parts 31 for defining closed liquid chambers are formed, extending from the rubber member 3 in the minor axis direction. When the inner ring 2 deformed into a circular shape is press-fitted in an outer cylinder so that the vibration damper rubber is compressed and deformed, and accordingly, the tensile stress of the rubber member 3 which has given during molding thereof is converted into a compression stress. Simultaneously, a tensile stress is effected in the wall parts 31 extending in the minor axis direction, but if an inner cylinder 4 is moved upward by application of a static load thereto, the above-mentioned force canceled thereby. Thus, the stress of the vibration damper rubber member 3 is turned into a compression, and the stress of the wall parts 31 are eliminated, thereby it is possible to exhibit an excellent durability.

Title: Manufacture of semiconductor device
Inventor: TAGUCHI MITSURU
IPC: H01L21/28
Filed: 1996-02-16
Abstract: PROBLEM TO BE SOLVED: To excellently fill up a connecting hole by maintaining the fluidity of a conductive film when the film is heated in a high-pressure reflow method at a high level. SOLUTION: Even when high-pressure reflow is performed while an Al oxide film formed on the surface of an Al-Cu film 5 is left when a wafer is carried in the air, a via hole 3 cannot be filled up completely with the Al-Cu film 5, but a void 6 is left in the hole 3, because the Al oxide film is hard and has a high melting point. Therefore, the Al oxide film is removed by performing Ar<+> sputter immediately before the high-pressure reflow after the Al-Cu film 5 is formed by sputtering. The Al oxide film may grow on the interface between the Al-Cu and Ti when the Al-Cu film 5 is laminated on the surface of a Ti- based film formed by using a CVD film forming method without removing a Ti oxide film in the case where the Ti oxide film exists on the surface of the Tibased base film.  Therefore, the growth of the Ti oxide film is prevented by removing the Ti oxide film by the same method immediately before forming the Al-Cu film 5.

Filed: 1999-02-08
Abstract: PROBLEM TO BE SOLVED: To greatly shorten an analyzing time by scanning the whole of a specimen with an electron beam diameter of a size of one pigment for finding location of an enclosure to be analyzed and reducing the beam diameter for surface-analyzing the location area in detail. SOLUTION: Firstly, an electron beam diameter is set to be substantially equal to that of one pigment, and the specimen whole surface ABCD is surface- analyzed by stage scanning for rough analysis roughly determining whether an enclosure exists or not and for estimating its location. In this case, A11, A12,... AMN represent pigments in surface-analysis based on stage scanning, and AJK represents a pigment including an enclosure. Then, an area large enough for covering a pigment area abed including the enclosure is surface-analyzed with an electron beam diameter reduced for finely analyzing the enclosure. In this case, a11, a12,... aMN represent respective pigments in surface-analysis based on beam scanning. In this way, the enclosure is analyzed in two steps.

IPC: G01N25/20
Filed: 1996-02-19
Abstract: PROBLEM TO BE SOLVED: To accurately measure a specific heat capacity of a solid or a liquid material in a short time within a temperature region from a room temperature to a heat-resistance limit temperature by a constitution wherein it is calculated it on the basis of a temperature rising ratio between reference and measurement specimens. SOLUTION: A plate shaped reference specimen 7 and a measurement specimen 8 are alternately placed on an identical measuring position by rotation of a specimen holder 9 by virtue of a position changing mechanism 11. A pulse laser is emitted on the measuring position from a laser heating source 1 which is common for the specimens 7, 8 and the rising of the temperatures of the rear sides of the specimens 7, 8 is alternately measured by a radiation thermometer 13. An output signal of the thermometer 13 is stored in a transient memory 14 to be transmitted to a calculation device 1 5, then a specific heat capacity of the specimen 8 is calculated based on a temperature rising ratio between both of the specimens, a reference value of specific heat capacity of the reference specimen and a mass ratio between the specimens 7, 8.  Since the specific heat capacity of the specimen 8 is obtained from the temperature rising ratio between the specimens 7, 8 based on the specific heat capacity of the specimen 7 and the radiation temperatures are measured on the identical measuring position, the specific heat capacity within a temperature region to a heat resistance limit temperature of the specimen or a heating furnace can be accurately measured.

Title: Pattern forming method
Inventor: YOSHIMI MAKOTO
IPC: H01L21/027
Filed: 1982-02-26
Abstract: PURPOSE:To enhance the throughput in a process of subjecting a base material by reactive etching by a method wherein isoamyl acetate (IAA) is used in a solution for the development of polymethyl methacrylate (PMMA), thereby the thickness of an unexposed film is not reduced during the developing process under an electron beam with an acceleration voltage of not lower than 30kV and precision and resolution in the process is improved. CONSTITUTION:An IAA solution is used to develop PMMA. A PMMA/IAA system, with the initial PMMA thickness set at 1mum and the IAA temperature set at 28 deg.C, suffers from no reduction in thickness in the unexposed part when the system is exposed to development under an electron beam with an acceleration voltage not lower than 30kV, for example, 40kV. The time needed for the development of a PMMA/IAA system to complete depends upon the temperature of the developing solution. When the temperature of the solution is not lower than 35 deg.C, developing speed is very high, and the process is completed within only 2min at 45 deg.C.
