Title: Production of easily releasable multi-layer structure
Inventor: TANAKA KYOJI
IPC: B65D77/38
Filed: 1990-05-29
Abstract: PURPOSE:To obtain a desired interlaminar strength, by subjecting a multi-layer structure having a specified layer structure to a specified heat treatment for reducing interlaminar strength. CONSTITUTION:A multi-layer structure, obtained by laminating a layer comprising a polyethylene resin and a layer comprising a polypropylene resin with each other under heating and then cooling the laminate, is heated to a temperature not lower than (the main melting peak temperature of the polyethylene resin) -20 deg.C and not higher than the main melting peak temperature of the polypropylene resin, and is then cooled so as to control the interlaminar strength between the layer comprising the polyethylene resin and the layer comprising the polypropylene resin. The layer comprising the polyethylene resin comprises a high density polyethylene, a linear low density polyethylene or the like, and preferably has a main melting peak temperature of 95-135 deg.C. The layer comprising the polypropylene resin comprises polypropylene singly or in admixture with polyethylene. The cooling after laminating is preferably a rapid cooling at a cooling rate of 10<1> to 10<5> deg.C/sec, with the temperature after the cooling being 0-80 deg.C.

Title: Electrically erasable programmable read-only memory
Inventor: SUCHIYUWAATO ROOJII
IPC: H01L27/115
Filed: 1988-06-03
Abstract: PURPOSE: To make a read-only memory programmable and erasable by using a low voltage and can be read extremely quickly and, at the same time, to reduce the chip surface area used by the memory by making a single polycrystalline silicon (polysilicon) layer to function as a floating gate above the channel of a sense transistor. CONSTITUTION: In an EEPROM memory cell 10, five N<+> -type areas are formed on and below the surface of a P-type substrate 5 by using an ordinary oxidizing technique. A polysilicon floating gate 38 is capacitively coupled with the source 34 of a sense transistor 30 through a gate oxide layer 37 and to the source 24 of a writing transistor 30 through a tunnel oxide layer 55 having a thickness of about 90Å. The floating gate 38, in addition, is extended to a point above the channel 35 of the transistor 30 so that the channel 35 can be inverted and an electric current can flow between the source 34 and drain 32 of the transistor 30 upon receiving a sufficient quantity of charges. An electric field oxide layer 57 separates the transistors 30 and 20 from each other by insulating the floating gate 38 from the substrate 5 below the gate 38.

Title: Twin roll type continuous casting method
Inventor: YASUDA KAZUMI
IPC: B22D11/06
Filed: 1992-05-29
Abstract: PURPOSE:To wind up a cast strip into a tight coil by winding the cast strip to inside together with an auxiliary sheet with a coiler and using a compact twin roll type continuous caster. CONSTITUTION:As the coiler 6 is arranged near the casting rolls 2a, 2b, the cast strip 1 coming out from the casting rolls 2a, 2b is wound before winding reaction force becomes intense without over-cooling. As the cast strip 1 just coming out from the casting rolls 2a, 2b is brittle, the cast strip is broken because it can not bear excess tension stress. Therefore, the tension is given to the auxiliary sheet 10, but as the auxiliary sheet 10 is formed with e.g. high strength rolled steel strip, this is not largely extended. The auxiliary sheet 10 giving the tension is wound by winding the cast strip 1 to inside. Therefore, at the time of winding, the wound cast strip 1 is wound while being tightly fastened by pressing the outer circumference. By this method, the cast strip 1 and the auxiliary sheet 10 are wound into the tightly wound coil.

Abstract: PURPOSE: To make adjustment possible and to improve the accuracy, without use of a balance adjusting spring, by fixing the both ends of the movable sides of upper and lower frames forming a spring portion, while making the respective end portions adjustable in balance, to the upper and lower ends of stationary and movable  frames.  
     CONSTITUTION: Upper and lower frames 4 and 5 are prepared by bending thein plates of permanent elastic material into a shape having a C-shaped cross-secti on to form bent portions 4a and 5a at their both side edges with regidity. At the positions 4a and 5a re partially cut away to form respective leaf springs 6 acting as springs. A balance adjusting span 9, which is bent inwardly into an L shape in a balance adjustable manner, is formed at each end of the upper and lower frames 4 and 5 at the side of a movable frame 3. When the two frames 4 and 5 are to be fixed to the  movable frame 3, this frame 3 is moved in parallel for adjustment to adjust the  elongation of the effective size of the leaf spring portion 6 at the side of the movable  frame 3 so that the blancing adjustment can be accomplished.

Title: Surface acoustic wave device
Inventor: ASAKAWA KIYOSHI
IPC: H03H9/145
Filed: 1980-10-02
Abstract: PURPOSE:To prevent expansion of the surface wave beam to improve the elecric characteristics, by weighting one electrode and by forming a waveguide path with metallic stripes. CONSTITUTION:In respect to an apodized electrode 21, for example, the cross width of the center and both end path are weighted wide and narrow respectively to realize a desired response characteristic. A waveguide path 23 formed with plural metallic stripes is provided between the apodized electrode 21 and an ordinary electrode in parallel with the propagation direction of surface waves. Since a speed where surface waves excited frm the electrode 21 propagate on metallic stripes 23 is lower than that on a nonelectrode free surface, the wave energy is shut in a region of a low propagation speed, and as the result, surface waves are propagated along metallic stripes 23 approximately.

Title: Flywheel power supply
Inventor: TANAKA KAZUHIKO
IPC: H02J9/06
Filed: 1994-05-26
Abstract: PURPOSE:To obtain a flywheel power supply strong against rolling of earthquake, for example, in which strict leveling work is not required. CONSTITUTION:Bearings fitted in a casing bear the rotary shaft 8 of a flywheel 2 which is rotated in the casing 1 to convert the electric energy into kinetic energy. The kinetic energy is stored and converted again, as required, into the electric energy. In such flywheel power supply, the flywheel 2 is balanced such that the rotary fulcrum 5 at the lower end of the rotary shaft 8 is matched with the center of gravity G. Since the difference in the horizontal distance between the center of gravity G of the flywheel 2 and the rotary fulcrum 5 is constantly zero, precession of the flywheel 2 does not take place even upon inclination of the rotary shaft 8 against a vertical line. This structure eliminates the need of leveling work at the time of installing the power supply and enhances the strength against rolling due to earthquake, for example.

Abstract: PURPOSE:To prevent a generation of cracks or delamination caused by deformation of a circumferential part of a substrate during a firing process by effecting the firing in a state that the circumferential part of a green sheet lamination body where a remaining stress concentrates is removed by cutting. CONSTITUTION:In a wiring region 2 arranged in a center of a surface, plural green sheets on which a conductor pattern has been printed are laminated in a mold of approximately rectangular shaped in a plan while keeping an interlayer-connection through vias formed by filling small holes with conductors.

Abstract: PURPOSE:To prevent the vibration of a bucket body by providing a damper capable of motion along the radial direction of a turbine disc and coming in contact with the platform section of the bucket body in space between the shank section of adjacent bucket bodies and constraint members fitted to front and rear sides of the shank section. CONSTITUTION:A prescribed range of a constraint member 9 in the vicinity of the external surface thereof is cut to form an annular recess 21 so that a gap 22 is formed between the rear side of a turbine disc body 1 and the rear side of the shank section 5 of a bucket body 2 when the member 9 is brought in contact with the rear side of the turbine disc body 1. A plurality of plate type dampers 23 are provided and formed to have a length suitable for insertion in space between respective small projections 20 of the platform section 6 of adjacent bucket bodies 2. According to this construction, a centrifugal force acts on the dampers 23, upon the start of engine, and the dampers 23 strongly contact the lower side of the platform section 6 of the bucket body 2. As a result, a frictional force is generated between each damper 23 and the platform section 6 of the bucket body 2, thereby preventing the vibration of the body 2.
