Title: X-ray take-out tube
Inventor: HAYASAKA TOUA
IPC: H05G1/02
Filed: 1981-10-26
Abstract: PURPOSE:To increase transmission factor of X-ray, by a method wherein excessive gas is exhausted by injecting hydrogen or helium gas little by little. CONSTITUTION:An X-ray take-out tube 8 has an X-ray transmitting window 7 in the side near by an X-ray source 2, an X-ray transmitting window 21 in the side near by a combination 15 of mask and wafer, a gas exhaust hole 22 near by the end in the side of the X-ray transmitting window 21, and a gas introducing means 20 near by the X-ray transmitting window 7. The X-ray take-out tube 8 is provided with a flange 4, and is fixed to a vacuum chamber 1 through a O- ring 5. When hydrogen or helium gas is introduced to the X-ray take-out tube 8 by the pressure little higher than the atmospheric pressure, the mixture of said gas with air is exhausted from the gas exhaust hole 22. As specific gravity of hydrogen or helium gas is less than that of the air, the air within the tube 8 is gradually replaced by said hydrogen or helium gas, and the X-ray take out tube 8 is filled with high-purity hydrogen or helium.

Title: Vacuum evaporation boat
Inventor: ENDO TORU
IPC: C23C14/24
Filed: 1992-06-04
Abstract: PURPOSE:To prevent the bumping of a material for vapor deposition at the vapor depositing temp. by using a cover just like a drop cover under a cover having holes. CONSTITUTION:The drop cover 4 is provided on a boat 1 in which the material for vapor deposition 5 is housed. A cover 3 having a hole and a cover 2 having two holes are fixed to the boat 1. When the temp. of the material for vapor deposition reaches the vapor depositing temp., the vaporized material passes through a space between the drop cover 4 and the boat 1 and the vapor is deposited successively from the holes of the cover 2 and the cover 3. At this time, since the temp. of the drop cover 4 approaches that of the boat 1, the temp of whole material for vapor deposition reaches the vapor depositing temp. Every time the vapor passes through the cover, the vapor is decreased in the entrainment of fine powder or splash.

Title: Circulating phase conjugate device for liquid
Inventor: YAGI TAKASHI
IPC: H01S3/30
Filed: 1990-06-28
Abstract: PURPOSE:To stably generate a phase conjugate wave even in the case of highly repeated incidence of a laser beam by connecting nozzles with a circulating line, a circulating pump, and a liquid pool between them and flowing liquid to the focus of the laser beam. CONSTITUTION:A vessel 1 is provided with a pair of nozzles 7 and 8 in positions corresponding to a focus 5 of the laser beam, which is made incident on the inside of the vessel 1, symmetrically to the axial line of the vessel 1, and the other ends of nozzles are connected with a circulating line 9, a circulating pump 10, and a liquid pool 11 between them. A laser beam 3 made incident on the inside of the vessel 1 through a convex lens 4 and a light-transmissive wall 2a forms the focus 5 in the vessel 1. When liquid is heated at this focus, liquid is easy to vaporize. When the pump 10 is driven at this time, liquid passes the focus 5 from one nozzle 7 and is sent toward the other nozzle 8. Thus, air bubbles generated at the focus 5 are restored while passing the circulating line 9 and are used again.

Title: Control device for operation of a clutch to be used in liquid torque converter
Inventor: NISHIMURA SADANORI
IPC: F16H61/14
Filed: 1982-10-01
Abstract: PURPOSE:To allow a sliding clutch plate to absorb a larger torque change likely to occur during acceleration or deceleration without requiring provision of an inertia valve at the clutch plate, by equipping the external fluid passage with a control valve, which shall reduce the pressure difference between the two sides of the clutch plate when a torque change is generated in the engine. CONSTITUTION:Orifice 31 is opened and closed by a control valve 29 installed in a divergent oil line LD 1, which diverges from the oil exhaust line LD. When a torque change is generated in the engine during acceleration or deceleration, a control means 30 is put in operation, and thus the control valve 29 is opened to sink the pressure inside the internal gap 16, which leads to a reduction of the pressure difference between the two sides of the clutch plate 19, whereby the force of engagement is weakened to provide easier slidablity, wherein the torque change is absorbed by slip of the clutch plate 19 to cause hindrance of power transmission between the input 13a and output 13b shafts.

Title: Power transmission device
Inventor: TAKADA HIROTOSHI
IPC: F16H61/662
Filed: 1992-06-08
Abstract: PURPOSE:To improve durability and power transmission performance by setting the traction factor of a contact part to a maximum value through regulation of a contact surface pressure at a contact part between a drive surface and driven surface, in a power transmission device for a toroidal type continuously variable transmission, such as an automobile transmission. CONSTITUTION:One sample disc 14 is arranged such that is pressed from above and below by means of three drive discs 15. The sample disc 14 is pressed through the upper drive disc 15 by means of load weights 16 and 16, and a maximum contact surface pressure Pmax of a contact surface between the outer peripheral surface of the sample disc 14 and the outer peripheral surface of each drive disc 15 is regulatable. In a relation between the maximum contact surface pressure Pmax and a traction factor mu the traction factor mu is increased during a time in which the maximum contact surface pressure Pmax attains a given value and decreased after it passes an approximately fixed area. Thus, after the maximum contact surface pressure passes an area where the traction factor is maximized, high transmission is not only effected but also a rolling factigue life is shortened. Thus, the traction factor may be set to a maximum value through regulation of the contact surface pressure.
