Title: Core supporting material
Inventor: NISHIMOTO MITSUO
IPC: B22C21/14
Filed: 1984-10-27
Abstract: PURPOSE:To obtain a core supporting material having substantial strength by supporting a core with a three-dimensional network structural body consisting of Ni or Ni alloy, casting the melt of Al or Al alloy and forming an Ni-Al intermetallic compd. consisting of the network body and the melt. CONSTITUTION:The core 2 of a casting mold 1 is supported with the three- dimensional network structural body 3 consisting essentially of the Ni or Ni alloy and the melt of the Al or Al alloy is cast therein. The body 3 combines with the melt to form the intermetallic compd. consisting essentially of Ni and Al. Such compd. constitutes part of the casting. The exact positioning of the core is thus made possible and the desired core supporting material which has substantial strength and constitutes part of the casting when cast is obtd. The core supporting material is used for high-pressure casting, etc. of an Al casting.

Title: Side undercover structure
Inventor: NAKAYA HIROYUKI
IPC: B62D25/20
Filed: 1994-09-21
Abstract: PURPOSE: To reduce the amount of air high in flow velocity striking against the front face of a front tire, and also reduce the pressure resistance of the front tire by forming a through hole for air to pass through at least in either one of the lower surface of a front bumper or a side under-cover. CONSTITUTION: When running wind W1 from the front of a vehicle is once separated from the lower end of the front surface 12B of a front bumper 12, air W2 flows from top to bottom toward a border area between the lower surface 12A and the front end periphery 16A of a side under-cover 16 through a through hole section 26 formed along the front face 12B of the front bumper 12. Running wind thereby does not adhere to the side under-cover 16 again, and it is pushed down. This constitution thereby causes the amount of air high in flow velocity striking against the front face of a tire to be reduced, and the pressure resistance against the front tire is thereby reduced.

Title: Racket
Inventor: KASAHARA KEISUKE
IPC: A63B51/02
Filed: 1991-09-06
Abstract: PURPOSE:To prevent slippage of a ball on a striking surface surely. CONSTITUTION:An oval frame part 3 with a long grip 2 is made. A gut 4 comprising an elastic material is applied on the frame 3 in a mesh to form a ball striking surface. A diamond particle layer 6 is formed on the surface of the gut 4 by bonding and mixing diamond particles. This allows increase in friction force which works on a ball from the ball striking surface 5 when the ball is struck so that the ball striking surface 5 can catch the ball surely. When the ball is struck back, a striking force can be secured at a specified part of the ball thereby facilitating the spinning of the ball.

Filed: 1991-09-06
Abstract: PURPOSE:To obtain a humidity sensor having high measuring accuracy by forming a macromolecular film as a moisture sensitive film, and thereafter making the surface of the macromolecular film conductive by ion implantation. CONSTITUTION:A platinum film is deposited on a quartz substrate 1 by sputtering. A lower electrode 2 is formed by patterning. Then, a polyimid precursor 3p is applied by spin coating (b). Then, condensation reaction is made to occur in the polyimide precursor 3p by the heat treatment at the cure temperature of 300-400 deg.C (c). Thus, a moisture sensitive film comprising a polyimide thin film 3 is formed. Then, ion energy and doze amount are controlled, and Ar ions are implanted into the surface of the film 3. Thus, an upper electrode 4 as a moisture permeability electrode is formed. Since the surface of the macromolecular film 3 is made electrically conductive by the ion implantation in this way, the thickness of the electrode can be adjsuted by controlling the ion energy. The resistivity can be controlled by controlling the doze amount. Thus, the humidity sensor having the high response without the dispersion in characteristics can be obtainted.

IPC: G01B3/04
Filed: 1988-09-07
Abstract: PURPOSE:To improve durability of graduations of a glass scale by providing metal films as the graduations. CONSTITUTION:A transparent glass substrate 1 is subjected to pretreatment and cleaning and then to electroless Ni plating. Photoresist 3 is applied on the surface of the electroless Ni-plating film 2 and a graduation image 4 is formed thereon by a photolithographic method including exposure and development.

Then by removing the photoresist 3 remaining on the electroless Ni plating film 2, the glass scale with graduations of Ni-plating film 2 can be obtained. Thereby, durability of graduations can be maintained for a long time even if the scale is used repeatedly.
