Title: Apparatus for causing laser beam to irradiate in vacuum
Inventor: AOSHIBA MITSUNORI
IPC: B23K26/12
Filed: 1989-04-28
Abstract: PURPOSE:To provide a vacuum laser beam irradiating apparatus where gas generated from a material to be irradiated with laser beam irradiation is screened with an inner aperture plate and sticking of impurity to expensive outer aperture plate can be prevented, by arranging the outer aperture plate between a cylindrical body arranged in a vacuum chamber and the atmosphere and the inner aperture plate in vacuum inside of this outer aperture plate. CONSTITUTION:After reducing pressure in the vacuum chamber 3 into high vacuum under condition of laying the material 6 to be irradiated on an irradiated material laying table 5, the laser beam is emitted from a laser beam oscillator 10. Then, the laser beam is transmitted through the optional opening part 19d in a backup member 19 through the outer aperture plate 13 in the vacuum chamber 3 and introduced to the vacuum chamber 3 through vertically moving member 22 and a first plate 23 and further through the inner aperture plate 16 to irradiate the material 6 to be irradiated. By this irradiation, the gas is generated from the material 6 to be irradiated, but a large part of the gas is screened with the inner aperture plate 16 arranged inside of the outer aperture plate 15 and on the outer aperture plate 15, sticking of impurity contained in the gas is little. Therefore, the expensive outer aperture plate 15 is not required to exchange often and economical burden is reduced.

Title: Semiconductor device
Inventor: UEDA KAZUYOSHI
IPC: H01L21/338
Filed: 1983-06-22
Abstract: PURPOSE:To contrive to improve the characteristics by reducing the gate-source series resistance by a method wherein semiconductor impurity layers serving as the source and drain regions are formed so as to incline from the source side to the drain side. CONSTITUTION:An N<+> layer 6 is formed by ion implantation from an oblique direction of an injection angle at 30-70 deg., with a provisional gate metal 4 and an SiO2 or SiN film 5 left on its side wall as mask, by the use of an N type impurity such as Si. Here, the oblique direction is a direction selected in such a manner that the source side of a GaAs MESFET becomes closer in the distance to the provisional gate, i.e., that inclination is present from the source to the drain. Next, a gate metal 9 is formed after removal of the metal 4. Since the GaAs MASFET thus formed has the source side N<+> close to the gate, and the drain side one away from the gate, the reduction of the source resistance can be contrived without causing the decrease of the gate-drain withstand voltage, resulting in the attainment to improve the FET characteristics which have not been conventionally obtained.

Title: Continuously variable transmission for vehicle
Inventor: KITANO KOJI
IPC: F16H47/06
Filed: 1988-05-09
Abstract: PURPOSE:To enable the restraining of creep torque at a low level via simple control by setting a gear change limit region in the low gear ratio side of a continuously variable transmission device at least in a fine throttle opening or less. CONSTITUTION:In the gear change region of a continuously variable transmission device 20 set within an electronic control device 47, there is provided a gear change limit region shown by a hatching area A. As a result, the continuously variable transmission device 20 is unable to shift a gear from an intermediate gear ratio to a low gear ratio in a fine throttle opening, and as a throttle opening B increases, the gear change limit region gradually becomes small. Finally, it becomes possible to shift a gear over the entire range of a lowest gear ratio to a maximum gear ratio at the throttle opening of 2/4 or more. By setting the gear change limit region as aforementioned, the continuously variable transmission device 20 is maintained at an intermediate gear ratio during idling as in creeping, and creep torque generated by a torque converter 3 is not amplified by the continuously variable transmission device 20. Consequently, creep torque transmitted to an axle becomes small.

Title: Fuel injection nozzle
Inventor: SAWARA MASANORI
IPC: F02M47/06
Filed: 1986-05-19
Abstract: PURPOSE:To reduce variations in fuel injection timing in a part relaying between the primary fuel injection with a high degree of control accuracy and each injection, thereby to prevent the output performance and emission performance of an engine from deteriorating, by providing a variable volume chamber in a high pressure fuel passage. CONSTITUTION:When the lift of a needle valve 3 in association with high pressure fuel is (1), a fuel inflow passage 9 is communicated with an annular groove 17 so that a piston 15 in a variable volume chamber 16 is displaced to a maximum volume position, and therefore fuel is charged thereinto. During this period the pressure of fuel lowers so that the needle valve 3 drops to terminate the primary fuel injection. If the fuel supply is continued, the needle valve 3 is again lifted, but fuel does not flow into the variable volume chamber 16, and therefore the needle valve 3 further continues its lift-up movement to terminate the main fuel injection. Simultaneously, a solenoid valve 21 is opened, and therefore, the piston returns to its original position. Accordingly, since the primary fuel injection control is made on the nozzle body 2 side, the responsiveness is satisfactory, and further, if the variable volume chamber 16 is employed in a two-stage fuel injection pump, a three-stage type fuel injection characteristic is obtained, and therefore, it is possible to prevent the output performance and emission performance in a part relaying between injection timings from deteriorating.
