Title: Forming method for laminate
Inventor: IKETANI KUNIO
IPC: B29C43/20
Filed: 1990-11-27
Abstract: PURPOSE:To prevent the outlow of resin from prepreg ends at the time of laminate forming and enhance the surface roughness degree and dimension stability of laminate by forming channels or holes on the surface ends of a metal mirror plate and disposing banks with the given height and length on said channels or holes. CONSTITUTION:Usually a metal mirror plate 1 is made of stainless steel, and channels 5 are formed on the two sides facing each other or four sides, and banks 2 for preventing resin flow are disposed. Required release papers, metallic foils 3, prepregs 4 or the like including banks are placed between the mirror plates 1 and heat pressurized to form a laminate. The height and length of the banks are fixed according to the thickness and size of the laminate to be laminate formed. Especially the height of the banks is not affected by the size of the resin flow at the time of forming. For example, in the case of 1.6mm thickness laminate, approximately 0.3-0.5mm is suitable, and in the case of 0.8mm thickness laminate, approximately 0.15-0.25mm is suitable, and in the case of 0.4mm thickness laminate, 0.08-0.12mm is suitable. As the outflow of resin is prevented by the banks, the thickness of laminates is uniform, and the distribution of resin base is also uniform, and the smoothness of the laminate surface is more superior.

Title: Semiconductor device and its manufacture
Inventor: ISHIZUKA SHUICHI
IPC: H01L21/318
Filed: 1998-10-26
Abstract: PROBLEM TO BE SOLVED: To reduce total capacitance between wirings by forming a semiconductor device, using a fluorine added carbon film (CF film) as an interlayer insulating film while using a boron nitride film(BN film) as a hard mask. SOLUTION: After a first CF film 21 which acts as an interlayer insulating film is formed, a hard mask 31 constituted of a BN film is formed on the CF film 21, and a specified trench pattern is etched on the hard mask 31. A trench for forming a wiring layer on the CF film 21 is etched by using the hard mask 31 as a mask, and a semiconductor device is manufactured by embedding Cu in the trench. Since the CF film and the BN film which have low relative permittivities are used in the semiconductor device, relative permittivity of the semiconductor device as a whole is reduced, so that the total capacitance between wirings is reduced.

Title: Polishing composition
Inventor: HORIE YUJI
IPC: B24B37/00
Filed: 1998-11-12
Abstract: PROBLEM TO BE SOLVED: To provide a polishing composition capable of improving the re- dispersibility of abrasive grains after leaving them over a long period of time and performing high precision, precision polishing, and provide a polishing composition capable of improving grinding force and performing high precision, precision polishing in a short time.

Inventor: HAYASHI KEIZO
IPC: G21K5/04
Filed: 1987-12-18
Abstract: PURPOSE:To widen an effective scanning region and to enhance a treating capacity, by scanning an electron beam along an orbit of a rectangular shape. CONSTITUTION:A scanning tube 6 has an irradiation window 4 of 45-180cm or so in length and 7-10cm or so in width. An electron beam 10 irradiates a matter 7 to be treated through a Ti or an Al window foil 5 covering the irradiation window. The electron beam 10 irradiates an area within the irradiation window 4 along an orbit of a rectangular shape expressed with the marks, A-B-C-D shown in the attached figure. In this way, a scanning length along a y-direction can be effectively doubled, therefore an electric current density for a unit time and a unit area can stay unchanged even if an electron beam current is doubled, and a burn-out of the window foil can be prevented. Therewith, a high electron beam current can be applied and a treatability is improved.

Abstract: PURPOSE:To improve the use efficiency of a memory by setting a size smaller than the actual size of printing in the bar code printer as a basic size and providing a means which stores a drawing of this basic size and enlarges and prints it. CONSTITUTION:Print data are inputted from a personal computer and received by an UART 7, expanded into dot constitution, and stored in a frame buffer 6. At this time, 3-dot/mm density is enough for the part (a) of only bar codes, so the data are drawn to the basic size which is a quarter as large as the actual size in the X (lateral) direction and as large as one dot string in the Y direction. Numeric data (b) are drawn in 12-dot/mm actual density. The numeric data (b) are printed in 3mm width, so 36 lines are printed without being enlarged. Printing of code (b) is enlarged four times in the X direction and one line is printed, its 37th line is read out again without updating the address of a buffer 6 to be read next, and this process is repeated four times in the X direction and 324 times in the Y direction, thus the printing operation completes.

Title: Auxiliary hydraulic pump
Inventor: DENISU REI BAABAA
IPC: F04B13/00
Filed: 1992-12-02
Abstract: PURPOSE: To obtain an efficient apparatus for providing an auxiliary supply source of compressed hydraulic fluid for a vehicle hydraulic system at a low cost in a simple way. CONSTITUTION: A ground-driven variable displacement pump 30 includes a piston 32. An outlet line 42 communicates fluid one way from a pump chamber 40 to vehicle circuits. An inlet line 46 communicates fluid one way from a fluid reservoir 14 to the pump chamber 40. A ground-driven rotatable cam member 50 reciprocates the piston 32. A spring 52 urges the piston 32 towards a full stroke position. A pilot line 28 communicates fluid pressure from a pump 12 to a pilot chamber 38. When the pump 12 is operational, the pressure in the pilot line 28 moves the piston 32 away from the cam member, thus de- stroking the pump 30. When the pump 12 stops, the pilot pressure drops, causing the pump 30 to go into stroke.
