Title: Method for burning ceramic compact
IPC: H01M10/39
Filed: 1992-03-26
Abstract: PURPOSE:To simplify the separation of a setter after burning a ceramic compact formed into a bottomed cylindrical shape, prevent a material to be burned from being damaged and improve the yield. CONSTITUTION:A ceramic compact 1 formed into a bottomed cylindrical shape with an opened lateral end (1a) downward is placed on a setter 2 and burned. The setter 2 is provided with a through hole 3 for allowing a gas to flow into an inner space (1b) of the material 1 to be burned. Since the pressure of the inner space (1b) of the material 1 to be burned is not lowered from that of the outside with the through hole 3 even if the burnt material 1 is taken out in a state of the setter 2 sticking thereto after the burning, the separation of the setter is simplified so much.

Title: Manufacture of extrusion molded joint of insulated cable
Inventor: KARASAKI TAKASHI
IPC: H02G1/14
Filed: 1987-04-23
Abstract: PURPOSE:To eliminate an irregular thickness of an extruded resin by providing a cable supporting base having a plurality of guide rollers at both ends of an extrusion metal mold. CONSTITUTION:Two series of parallel crosslike rollers 5 made or 4 guide rollers are disposed at upper and lower, and right and left sides as a supporting base to support a CV cable 1 at both ends of a metal mold 3. Thus, the extension of the cable 1 from the mold 3 can be escaped in a longitudinal direction at its supporting point, but a bending moment is not generated at a fulcrum, no eccentricity occurs in the mold, and the extension of the cable due to temperature rise can be absorbed at a cable offset. Thus, an eccentricity of an extruded resin is eliminated at the extrusion molded joint of an insulated cable.

Title: Wind mill pump
Inventor: MASAKAINA MASARU
IPC: F03D9/00
Filed: 1981-06-29
Abstract: PURPOSE:To transmit the rotary force of a wind mill efficiently to a pump by freely changing the direction of the wind mill in accordance with the direction of the wind. CONSTITUTION:The wind mill 1 will rotate while receiving the wind from the front, thereby a crank disc 5 will rotate also. Consequently the rolling member 10 will roll up and down around a fulcrum and said up-down motion is transmitted to a coupling rod 6. The motion of the coupling rod 6 is transmitted through a ball coupling 9 to a coupling rod 8 then a piston 12 will reciprocate to perform the pumping. Upon changing of the wind direction, the vertical vane 11 will function to rotate the rotary table 3 to direct the wind mill 1 toward the wind. The rotation of the coupling rod 6 due to the rotation of the rotary table  3 is not transmitted to the coupling rod 8 below thereby the coupling rod 8 will transmit only the up-down reciprocal motion to the piston 12a.

Carbon fibers 2 are easily wetted by phosphoric acid electrolyte and have many voids, so that the phosphoric acid with the distributed condition turned uncontinuous is coupled with other phosphoric acid electrolyte. Thereby a fuel cell can be equipped with an electrode catalyst layer having excellent characteristics and reliability.

Abstract: PURPOSE:To make it possible to set installation intervals between a electrodes to be extremely narrow by applying an electrode hairline around the conductor core of which is covered by an insulating layer, as an electrode to and current to a resistant heating element. CONSTITUTION:For an electrode hairline 1, the periphery of a conductor core 3 made of various types of conductor metals such as copper, aluminum or gold, etc. is covered by an insulating layer 4 of polyurethane or polyimide, etc. Adding signal current to the electrode hairline 1 causes current to flow from the end surface of the electrode hairline 1 to the end surface of a common electrode 7 through a resistant heating element 5, and only the resistant heating element 5 at that part is heated.

Title: Picture signal band compression system
Inventor: ITO HIROYASU
IPC: H04N19/50
Filed: 1986-05-06
Abstract: PURPOSE:To execute a band compression with high compressibility to the input digital picture signal of an animation without the deterioration of reproduced picture quality by dividing the input digital picture signal into low-frequency component and high-frequency component and executing an inter-frame encoding. CONSTITUTION:When an input digital picture signal is set as a subsample circuit by a subsample circuit 1, the low-frequency component of the input digital picture signal is obtained and the low-frequency component is encoded by the first inter-frame encoding circuit 3. Therefore high compressibility is obtained by the inter-frame encoding of the signal which has a few samples. By executing a linear interpolation to the output of the subsample circuit 1 by means of an interpolation circuit 2, the number of the samples which is the same number of the input digital picture signal is obtained and the high-frequency component of the input digital picture signal is obtained when the interpolation output signal is substracted from the input digital picture signal by a subtracter. The high-frequency component is encoded by the second inter-frame encoding circuit 4. Thus even in the case of the animation, the high compressibility with the aid of the inter-frame encoding is obtained.

Title: E-ring holder
Inventor: FUJITA AKIO
IPC: B23P19/02
Filed: 1984-05-21
Abstract: PURPOSE:To facilitate the holding of an E-ring by forming a penetration hole contiguous to the upper and lower parts on the center line of a pair of holder parts and spot facing parts onto the upper and lower surface sides and inserting a penetration shaft and the upper and lower disc members for spot facing surfaces, thus regulating the shift of a holder in the vertical direction. CONSTITUTION:Spot facing parts 12 and 13 are formed onto the upper and lower surfaces so as to be contiguous to the holder parts 3 and 4, and disc members 14b and 15 are installed onto a shaft part 14a and over and under the shaft part, and the intermediate projections 16 and 17 in flange form between the upper and lower spot facing parts 12 and 13 are nipped by the disc members 14b and 15. Therefore, when the holder parts 3 and 4 are to be relatively shifted in the vertical direction, the holder parts contact with the disc members 14b and 15 having the flange-shaped projections 16 and 17 in the vertical direction, and the movement is restricted, and the vertical deflection is not generated on the holder parts 3 and 4. Since the horizontal movements of the holder parts 3 and 4 are not restricted, the holder parts 3 and 4 can spread smoothly in the horizontal direction, when an E-ring is inserted between flat grooves 9a and 10a. Therefore, the E-ring can be nipped safely and easily, and working efficiency can be improved.
