Patent JP-H06227042-A (JP)
Title: High-quality printing method
Inventor: SATO FUMITAKA
IPC: G06T11/20
Filed: 1993-02-08
Abstract: PURPOSE:To obtain a high-quality printing method capable of performing high- quality printing free from a variation in line width without hinting processing and capable of enhancing a printing speed. CONSTITUTION:A coordinate value of a lower outline is found by adding a line width DELTAy, which has been previously scaled as an integer, to a y-coordinate value of an upper outline, which has been previously scaled as an integer. Printing is made by dots of the number for the line width, as shown by a figure. In this manner, the line width DELTAy is constant regardless of the y-coordinate value of the upper outline. Therefore, in both two examples (A) and (B), printing of a constant line width can be made irrespective of the positions of outlines on a printing dot grid.

Title: Rotary heat exchanger
Inventor: INOUE SHIYUUICHI
IPC: F28D11/04
Filed: 1978-02-22
Abstract: PURPOSE: To keep a rotary heat exchanger sealed stably, by preventing the sealer from adhering.  
     CONSTITUTION: The sealing device of this rotary heat exchanger is composed of a disc 24 revolvable together with a hollow rotary shaft 10 and an annular disc 26 made of synthetic rubber fitted not in contact with a surface 25 of the disc 24 facing the upper stream of the inner fluid. The sealing device functions as a seal between fluids by sliding both discs 24, 26, by virtue of a pressure difference P 3  between a feed chamber 11 and exhaust chamber 12 produced only when the rotary heat exchanger is actuated and the inner fluid flows. When the heat exchange is interrupted and the fluid stops flowing, the said pressure difference P 3  disappears and both discs 24, 26 are kept separated. This means that the synthetic rubber of the sealer does not adhere or stick to the metal of the other sealer even if the heat exchanger is interrupted for a long period, keeping its stable sealing property.

Title: Lateral transistor
Inventor: NOMURA YOSHINOBU
IPC: H01L29/72
Filed: 1986-01-31
Abstract: PURPOSE:To double the capacity of current of an emitter by doubling the area of an emitter region while the area of a pattern size is the same with that of conventional ones. CONSTITUTION:The peripheral length of a P-type emitter region 27 is increased by a construction wherein an N<+> type base contact region 26 is disposed on the center, the emitter region 27 around the region 26, and further a P-type collector region 28 around the region 27. Since the emitter region 27 is disposed around the base contact region 26, the peripheral length of an emitter 27 can be made about three times larger than that of conventional ones while the area of a pattern size is made equal to that of conventional ones. Accordingly, the current capacity can also be trebled approximately. The peripheral length of the base contact region 26 is shortened, since this region 26 is disposed in the center. However, only a current of 1/hFE of a collector current (substantially equal to an emitter current) flows to a base of a transistor, and therefore the current capacity of the emitter region 27 is not restricted by the size of the base contact region 26.

Title: Resin molding and manufacture of resin connecting type member
Inventor: TAMURA ETSUO
IPC: C03C6/00
Filed: 1999-01-28
Abstract: PROBLEM TO BE SOLVED: To hold a surface roughness of a mold release agent layer and an accuracy of a surface shape in the same degree as those of a mold surface and to form the layer without reducing a production efficiency by spraying gas to a surface of a mold before molding a resin and forming the layer. SOLUTION: Since gas is sprayed to a surface of a mold to form a mold release agent layer of an extremely thin gas component or the like is formed, a surface roughness of the layer and an accuracy of a surface shape can be held in the same degree as that of the surface of the mold. Since the step of spraying the gas is a step of simply completing in a short time, the step can be assembled in the step of molding a resin. Since a force (mold release force) necessary in the case of releasing a resin molding or a resin connecting type member is reduced, a surface roughness of the layer formed on the surface of the mold and an accuracy of the surface shape can be held in the same degree as that of the mold, and the layer can be easily formed during manufacturing step without lowering a production efficiency.
