Title: Production of fiber reinforced aluminum alloy
Inventor: EZOE SEIJI
IPC: C22C47/00
Filed: 1985-12-25
Abstract: PURPOSE:To produce a fiber reinforced Al alloy having an optional shape and high strength by packing a heated short fiber reinforcing material into the pressurization chamber of the 1st casting mold and penetrating a molten Al alloy under the pressurization therein and injecting the molten alloy into the molding chamber of the 2nd casting mold and solidifying the same. CONSTITUTION:The heated short fiber reinforcing material 25A is packed into the pressurization chamber 5 of the 1st casting mold 3 and at the same time, a reducing valve 17 is raised and the pressure in the chamber 5 is reduced by a vacuum pump 23. A plunger 1 is then raised to open an aperture 7 and the molten Al alloy 24A in a molten metal pool 8 is introduced into a molten metal holding chamber 4. After a punch 4 is once raised up to the bottom surface position of the plunger 1, the plunger 1 and the punch 2 are simultaneously lowered to pressurize the molten Al alloy 24A and to penetrate the same among the short fiber reinforcing materials 25A in the chamber 5 under the reduced pressure. The valve 17 is then lowered to close a valve hole 14 of the drag 12 of the 2nd casting mold and a truncated circular cone shape valve 15 is lowered into the molding chamber 20 to open the aperture 6. The composite molten alloy stock is further injected into the chamber 20 formed of the recesses 11, 12 of the cope 9 and drag 12 of the 2nd casting mod by the punch 2 and is solidified therein.

Title: Manufacture of semiconductor device
Inventor: TANAKA KOZUE
IPC: H01L27/04
Filed: 1987-11-25
Abstract: PURPOSE:To reduce the logical description quantity and to ensure the highly effective design of a semiconductor device despite a deep hierarchy by using a net name proper to an LSI to perform the logical design of the lowest hierarchy and producing automatically an external terminal by means of the net name for production of a higher rank hierarchy. CONSTITUTION:The proper net names N1-N5 are peculiar within a chip 11. In case the nets of the same name are obtained, the nets to be connected to each other are decided even though no logical description is carried out between the hierarchies. Therefore, a designer uses these net names to describe the blocks 12-15 individually for designing and collects the necessary blocks based on the net names. Then, the higher hierarchies 16 and 17 are produced together with the automatic generation of an external terminal in terms of the net names connected to outside. These produced hierarchies are collected again based on the net names and the higher hierarchies are produced. In such a way, the logical description value is reduced and a semiconductor device is designed with high efficiency despite a deep hierarchy together with easy corrections.

Title: Electromagnet device
Inventor: HISHINUMA YASURO
IPC: F16K31/06
Filed: 1995-10-23
Abstract: PROBLEM TO BE SOLVED: To suppress the generation of hysteresis by mounting a nonmagnetic ring impeding magnetic lateral force generated between the end face of a movable iron core and a yoke and coming in sliding contact with the inner peripheral surface of the yoke so as to guide and support the axial movement of the movable iron core. SOLUTION: When a current is applied to excite a cylindrical solenoid coil 5 through a connector 15, magnetic flux generated from the cylindrical solenoid coil 5 forms a magnetic path A making a circuit of a fixed iron core 3, a yoke 4 and a movable iron core 1. The movable iron core 1 is thereby moved and magnetically attracted to the fixed iron core 3, but in this case, since a copper ring 20, a nonmagnetic substance, is mounted on the tail end side peripheral surface of the movable iron core 1, magnetic flux obliquely intersecting the tail end part of the movable iron core 1 is intercepted.  At the same time, a sufficient gap is formed between the greater part of the peripheral surface of the movable iron core 1 and the inner peripheral surface of the yoke 4 by the thickness of the copper ring 20 so as to effectively suppress the generation of hysteresis in the reciprocating motion of the movable iron core 1.

IPC: H01L27/10
Filed: 1993-11-29
Abstract: PURPOSE:To provide a semiconductor memory device, which can have a large capacity with the simple structure and can sufficiently withstand the severe environment. CONSTITUTION:Many memory elements 111, 112,... are arranged in lines and columns. The memory elements 111, 112,... are constituted of single-crystal islands, which are demarcated with insulator regions 12, respectively. A conductor layer region 14 is formed at the lower part of the region 12 through a thin insulating layer. The surface part of the specified element is made an amorphous layer 16 caused by the deterioration of the crystal property by the writing of information. When the surface, on which the memory elements 111, 112,... are arranged, is scanned with a coverged particle beam, a channeling phenomenon occurs in the memory element without the amorphous layer 16. The particle beam passes through the single-crystal layer and the insulating layer 13 and reaches the conductor layer region 14, and a current is generated. When the amorphous layer 16 is present, the particle beam does not reach the conductor layer region 14, and the current is not generated.

Filed: 1997-10-15
Abstract: PROBLEM TO BE SOLVED: To condense a sample gas using an adsorbent deteriorated in performance subsequent to oxidation in an odor measuring apparatus using an odorant sensor of an oxide semiconductor. SOLUTION: When a sample component adsorbed to an adsorbent in a collecting tube 22 is to be sent to flow cells 28a, 28b, N2 is sent to the collecting tube 22 via a nitrogen gas path 15 and a six-way valve 21, and the collecting tube 22 is heated by a heater 23. The N2 including the sample component first passes the flow cell 28a where an odorant sensor 29a constituted of a conductive polymer is set. Thereafter, the air supplied with a predetermined pressure from a tank 34 storing the air is mixed with the N2 , and is sent through the flow cell 28b where an odorant sensor 29b of an oxide semiconductor is installed. Thereafter, O2 does not come in touch with the adsorbent when the adsorbent in the collecting tube 22 is heated, while O2 is adsorbed to the odorant sensor 29b. Accordingly the sample component can be detected.
