Title: Method for forming insulation film and manufacture of p-type semiconductor element
Inventor: KATAOKA TOYOTAKA
IPC: H01L21/318
Filed: 1998-03-10
Abstract: PROBLEM TO BE SOLVED: To avoid the reduction of a current drive capacity due to the infiltration of nitrogen atoms into a channel formation region by forming an insulation film by a first process for heat-treating a semiconductor layer in a nitriding atmosphere, where an atmospheric temperature is determined to be at a specific range and a second process for heat-treating the semiconductor layer in an oxidizing atmosphere. SOLUTION: In a first process, a semiconductor layer 10 is heat-treated (nitriding treatment) in a nitriding atmosphere at an atmospheric temperature of 200-500 deg.C, thus forming an extremely thin nitride film on the surface of the semiconductor layer 10. By heat-treating (oxidation treatment) the semiconductor layer 10 in an oxidizing atmosphere in a second process, the oxidation of the semiconductor layer 10 advances due to the oxidation seed through a nitriding film such as a silicon nitriding film, thus forming an oxide film such as a silicon oxide film on the semiconductor film 10 in the interface between the nitriding film and the semiconductor layer. In this manner, by forming an insulating film 2 in two stages, the amount of nitriding atom contained in the insulation film near the surface of the semiconductor layer can be reduced.

Title: Control method in alphabetic printing
Inventor: SHINOHARA HIROYUKI
IPC: B41J2/51
Filed: 1988-03-11
Abstract: PURPOSE:To enable a printing aligned in a line at a base line even if characters of different magnifications are mixed, by a method wherein, a character magnification of a line to be printed is obtained, a value over a base line of a character font base size is subtracted from a base line coordinate, and a printing start position is obtained by multiplying this value by the magnification. CONSTITUTION:Because all character magnifications (specified by a user) per line are registered in a character magnification table constructed by a RAM 11, a printing start position is obtained from a character magnification per line. From the character magnification table a maximum magnification in one line is obtained, and a printing start position S to the obtained magnification is calculated by a formula of printing start position = base line coordinate Y-(X-a)x magnification. The base line coordinate Y is calculated by the number of lines and the line modifier in a document. The value (a) is a ratio below the base line Y and assigned for every character synchronously with outline font control information. The value X is a basic font size. By calculating a printing start position by the formula, a base line coordinate Y is made constant regardless of a character magnification.

IPC: B60K11/08
Filed: 1983-04-05
Abstract: PURPOSE:To improve the heat exchange efficiency of an auxiliary cooling element, by providing an air inlet port in a part of a splash over. CONSTITUTION:Outside fresh air taken in through a front air inlet port 37 is guided to an auxiliary cooling element 41 by an upper panel 33, walls 9, 11 and a floor 19 to perform cooling by the air. After the cooling, the air is discharged to the outside through an air outlet port 39. The auxiliary cooling element 41 is thus always supplied with the cooling wind. The cooling element is not directly affected by a stone flipped during the movement of a vehicle, splashes, etc. A tongue is cut and erected at the air outlet port 39 so that negative pressure is very likely to occur near the port. According to this constitution, the efficiency of the discharge of the air is enhanced to improve that of intake of the air to heighten the cooling performance.

Title: Axial piston pump
Inventor: KAJIKAWA HIROMI
IPC: F04B1/20
Filed: 1991-03-22
Abstract: PURPOSE:To increase a delivery amount of working liquid without increasing the number of revolutions of a motor and to reduce the generation of noise through reduction of pulsation of a liquid pressure to a value as low as possible. CONSTITUTION:First - third pistons 17-19 are repeatedly reciprocated in a sine curveform manner in cylinder holes 11-13, respectively, along a cam surface alphaof a cam plate 30. A maximum protrusion part and a maximum recessed part reciprocated both twice per one full turn are formed in the cam surface alpha, and a first or a third cam plate 30 is reciprocated two times each time the cam plate 30 is rotated one time. As a result, a delivery amount of working liquid per one full rotation of the cam plate 30 is increased. Since the first and the third piston are peripherally disposed, delivery pressures from the first and third pistons are changed in a state to displace in a phase from each other, and a delivery pressure through a delivery port 7 is changed according to the highest delivery pressure of the delivery pressures of the first or the third piston. As a result, the fluctuation in a delivery pressure of an axial piston pump 1 is reduced and pulsation of a liquid pressure is also reduced.
