Title: Combustion chamber of internal combustion engine
Inventor: SUMIYOSHI MASAHARU
IPC: F02B23/08
Filed: 1977-09-09
Abstract: PURPOSE: To improve combustion efficiency by means that a protrusion with its axis shifted from the axis of a piston moves into the hollow space of a cylinder head to produce turbulance in a combustion chamber.  
     CONSTITUTION: A protrusion 12 which moves into a hollow combustion chamber 6 at TDC of a piston 3, existing in a cylinder head 4 and having a suction and an exhaust valve 7, 9 and an ignition plug 11, is made on the head of the piston 3, with its axis shifted aside from the axis of the piston 3. At TDC of the piston, the primary and the secondary combustion chamber 6a, 6b appear on the upper and lower side of the protrusion 12. In a compression stroke, the mounted protrusion 12 shifted aside, makes mixture gas in the secondary chamber 6b squished into the primary chamber 6a as turbulance so that the mixture gas can be burnt effectively in the primary chamber 6a.

Inventor: NAGURA TOSHIKAZU
IPC: G06K19/07
Filed: 1999-04-15
Abstract: PROBLEM TO BE SOLVED: To change communicating characteristics by an action from the outside part, without destroying the appearance of an IC card after the completion of the IC card. SOLUTION: This noncontact IC card is equipped with an antenna resonance circuit, having an antenna and a capacitor for the transmission and/or reception of data with the outside part.

Title: Positioning control device
Inventor: HIRAI NORITSUGU
IPC: G05D3/12
Filed: 1986-05-12
Abstract: PURPOSE:To stop a control object shaft to a constant position in the same way even when a pulse generating device is linked so as to rotate in the same direction to a motor and even when it is linked so as to rotate in the opposite direction by changing over optionally the output level of a rotating direction discrimianting circuit and adding it to a counter circuit by a conditions selecting means. CONSTITUTION:When a motor 1 is rotated to a normal rotating side and a constant position stopping command is inputted, the speed is reduced up to a creeping speed while the motor 1 is normally rotated. On the other hand, a PLG 19 for detecting a position outputs the pulse of the phase higher than an A phase and a B phase, and a pulse generating device direction discriminating circuit 20 outputs the signal of a level '1' in accordance with these phase relations. Since the signal of a level '0' of a conditions setting device 29 is applied to a level interting circuit 30, the signal of the level '1' outputted from the pulse generating device direction discriminating circuit 20 is changed to the level '0' and applied to the U/D terminal of a counter circuit 22. Consequently, when the counter circuit 22 starts the counting-down and a switch 15 is closed, the motor 1 reduces the speed as it does and a final shaft can be stopped to a constant position by a final stopping position.

Title: Rubber fishpass
Inventor: FUJIEDA TAKASHI
IPC: E02B8/08
Filed: 1999-04-15
Abstract: PROBLEM TO BE SOLVED: To restrict the occurrence of dry up of a fishpass by eliminating the runoff of river water than necessary by providing a rubber weir which is raised by controlling the inner pressure at the inlet portion of running water in fishpass and a partition wall constituted with a rubber bag body for varying the height by controlling the inner pressure in the middle of the fishpass in the longitudinal direction. SOLUTION: A raised type mini-rubber weir 3 installed to a concrete surface at the inlet of running water in a fishpass 1 changes its height by the internal pressure control by supply and exhaust air from a compressor. Also, a partition wall 4 consisting of a rubber bag body provided in the middle of the longitudinal fishpass 1 has an air chamber 4c made between a rubber sheet 4b adhered to the bottom of a water channel 2 and an airtight-sealed air chamber 4c, and the height of the partition wall can be changed by expanding and shrinking the rubber sheet 4a by the inner pressure control in the air chamber 4c by the supply and exhaust air from a compressor. In this way, the height of the rubber weir is made smaller thereby maintaining the function of the fishpass and the amount of water volume from the rubber weir can be controlled.

Title: Composite magnetic substance having function to control diamagnetic field
Inventor: MATSUSHITA AKIRA
IPC: H01F10/32
Filed: 1999-03-11
Abstract: PROBLEM TO BE SOLVED: To determine the magnetic mode by bringing many composite magnetic components bonded directly or indirectly through an intermediate layer into relatively close contact with each other into a specified shape. SOLUTION: Bistable magnetic components 1 and fixed magnetic components 2, both of which have uniaxial magnetic anisotropy, are magnetostatically bonded directly or indirectly through an intermediate layer into a composite magnetic component 3. Many of such composite magnetic components 3 are brought into close contact with each other into an integral body to form a composite magnetic substance 4. When an external magnetic field is applied in the forward direction to the composite magnetic substance 4, a diamagnetic field 5 is canceled. At the same time, by magnetic cooperation of the external magnetic field applied in the forward direction and the fixed magnetic components 2 magnetized in the forward direction, each bistable magnetic component 1 is rapidly reversed to the right and comes into a reset state wherein it is parallel with the fixed magnetic components 2.  When the work of the external magnetic field is removed, each bistable magnetic component 1 is rapidly reversed again by a control function of a diamagnetic field 5 generated autonomously and comes into a set state wherein it is antiparallel with the fixed magnetic components 2.

Title: Pellicle for lithography
Inventor: KASHIDA SHU
IPC: G03F1/62
Filed: 1999-04-16
Abstract: PROBLEM TO BE SOLVED: To provide a pellicle for lithography excellent in resistance to irradiation with excimer laser light by specifying the intrinsic viscosity of an amorphous perfluoropolymer used for a pellicle film. SOLUTION: The material of the pellicle film of the pellicle used for photolithography is an amorphous perfluoropolymer having repeating units of the formula and 0.25-0.60 dl/g intrinsic viscosity. In the case of <0.25 dl/g, resistance to irradiation with excimer laser light lowers. In the case of >0.60 dl/g, the terminal groups of the polymer may not be thoroughly stabilized because of its excessively large molecular weight and the polymer may not be thoroughly purified by filtration because of its high viscosity. As a result, the polymer has a chemically and optically labile chemical structure or resistance to irradiation with excimer laser light lowers owing to residual impurities.
