Title: Manufacture of porous plate by casting
Inventor: ICHIKAWA HIROAKI
IPC: B29C39/26
Filed: 1981-07-15
Abstract: PURPOSE:To obtain a subject porous plate through prevention of the production of burr, by a method wherein an elastic sheet is nipped and tightened between a low mold, having convexities and concavities, and an upper mold, and a casting material is injected in the concavities in the lower mold while pressurization takes place. CONSTITUTION:An elastic sheet 7 is positioned between the nip formed by a lower mold 5, having convexities 10 and concavities 11, and an upper mold 6, a pressure in a space between the two molds is reduced to 10mm.Hg or less, and the elastic sheet 7 is pressurized by a pressure of about 1kg/cm<2> by tightening a stationary board 3 and a moving board 4 to enable the convexities 10 to slightly cut into the elastic sheet 7. Under said pressurization, a casting material 13, such as polyester polyurethane, is injected into the concavities 11 in the mold 5, and vulcanization takes place at 100 deg.C for about an hour to obtain a desired molded product 1.

Title: Pattern forming method
Inventor: SUGIMOTO NAOAKI
IPC: G03C1/00
Filed: 1988-05-07
Abstract: PURPOSE:To eliminate a preliminary photosensitization process by employing polyimide soluble to an alkaline developer solution instead of a first positive type resist film formed on a substrate in a conventional process. CONSTITUTION:A polyimide film 12 soluble to an alkaline developer solution is formed on a substrate 11 comprising semiconductor or a thin film, etc., which has a flat or uneven surface. The polyimide film 12 has thickness thicker than the height of the unevenness of the substrate 11. By the use of polyimide soluble to an alkaline developer solution for formation of the polyimide film 12, a resist film 13 formed on the upper layer of the polyimide film 12 is selectively exposed. Hereby, the polyimide film 12 is also holed when the resist film is holed by the developer solution.

Abstract: PURPOSE:To effectively compensate for various eccentric aberrations by appropriately arranging each lens element. CONSTITUTION:The system has a first group L1 having a positive refractive power and a second group L2 having a negative refractive power in the order from an object side. The group L2 has a 2a group L2a having a negative refractive power and a 2b group L2b having a positive refractive power. The focusing is performed by moving the 2a group L2a in the direction normal to the optical axis.

Filed: 1997-04-30
Abstract: PROBLEM TO BE SOLVED: To prevent the failure of a feeder (cabtyre cable) connected to an electric motor which rotationally drives an exciting machine by the resonation with the exciting machine. SOLUTION: The exciting machine 1 is suspended by a hanger 5 via springs 8, 9 and a shaft 6. A spring seat 7 is buffered against the exciting machine 1 so as not to vibrate vigorously. Part (B part) of the cabtyre cable 10 is mounted at the spring seat 7 by means of a holding member 15 which is a rigid member without the intervention of a buffer member. As a result, the trouble by vibration does not arise at the point of the cabtyre cable 10 below the mounting part B (area near a power source). Since the part B is short, the part does not resonate with the exciting machine 1.
