Title: Coupling device for rotor blade of turbine
Inventor: SUZUKI TOSHIO
IPC: F01D5/22
Filed: 1989-10-31
Abstract: PURPOSE:To prevent generation of large stress due to lug restraint by forming at least either of the seat surface of the lug and the end face of a sleeve, which belongs to a coupling device for rotor blades of a turbine, in a smoothly curving surface form. CONSTITUTION:Adjoining rotor blades 12, 12 of a turbine are coupled movably by a sleeve 13 fitted with lugs 16, 16 which protrude at both side ends of a boss 15. Therein the end faces 13a, 13b of the sleeve 13 are curved with convex outward. Clearances CL are set between the seat surfaces of the lugs 16a, 16b and the sleeve 13, and the sleeve 13 is movable in the circumferential direction of the turbine impeller. This smoothens the motion of the sleeve 13 under the period the rotation is rising, and there is no fear of generation of large stress in the rotor blade 12 due to sticking of the lugs 16a, 16b with the sleeve 13.

Title: Driving device for optical device
Inventor: KAWAKAMI EIGO
IPC: G02B3/14
Filed: 1986-11-27
Abstract: PURPOSE:To obtain a stable optical property without decentering an optical axis, by providing an optical device having the optical axis and consisting of an elastic member, a lens barrel, an elastic supporting member which supports the optical device for the lens barrel and provided with elasticity to hold the circumferential plane of the optical device with an equal interval, and a driving means which presses the elastic supporting member in the direction of the optical axis. CONSTITUTION:The optical device 1 is pressed with peripheral parts, and its surface shape is deformed, thereby, a focal distance as the optical device is shortened. Adversely, since the elastic supporting members 5a-5b intend to restore to their original positions due to their elasticity by moving an annular movable member 6 leftward, as a result, an elastic body 1 is pulled from the periphery, then, the radius of curvature of the surface of the elastic body is increased. Consequently, the focal distance as the optical device can be increased. Thus, it is possible to control the optical surface shape of the elastic body 1 with high accuracy by changing the position of the annular movable member 6 in a direction of the optical axis. In such a way, it is possible to eliminate the possibility of decentering of the optical axis at the time of varying a focal point.

Title: Electrostatic chuck
Inventor: KITAZAWA KENJI
IPC: H01L21/3065
Filed: 1993-11-11
Abstract: PURPOSE:To prevent a conductive layer and an insulating layer from separating from each other by a method wherein an aluminum nitride film as thick as prescribed is formed on the surface of a base of metal or conductive ceramic prescribed in thermal expansion coefficient. CONSTITUTION:An electrostatic chuck 1 is composed of a base 2 of metal or conductive ceramic and an aluminum nitride thin film 3 formed on the surface of the base 2. The base 2 itself has a thermal expansion coefficient of 4.0X10<-6>/ deg.C to 6.0X10<-6>/ deg.C at a room temperatures to a temperature of 800 deg.C. If the base 2 has a thermal expansion coefficient out of the above range the aluminum nitride thin film 3 separates easily from the base l due to a difference of thermal expansion coefficient between the base 2 and the thin film 3 when the base 2 is kept at a high temperature in a semiconductor manufacturing process, so that the electrostatic chuck 1 is deteriorated in reliability and long term stability. The aluminum nitride thin film 3 formed on the surface of the base 2 is set as thick as 0. 001 to 1.0mum, especially 0.001 to 0.3mm. If the thin film 3 is set in thickness of the above range of thickness, it is lessened in service life and attracting force.

IPC: A61F13/49
Filed: 1994-10-24
Abstract: PURPOSE: To eliminate a feeling of physical disorder and require a small storage place by using a bag structure made of waterproofing material for a section in contact with the anal, forming a slit or a hole on the structure at a position in contact with the anal and applying a pressure sensitive adhesive to the surrounding area of the slit or hole in contact with the buttocks. CONSTITUTION: A pressure sensitive adhesive tape 3 is attached to the rear end 2 of a diaper for fastening the front and rear ends 1 and 2 thereof at two sides for use. The section of the diaper in contact with the anal is double- structured as shown by a dotted line, and bag type made of a waterproofing material. A slit 5 for taking stool into a bag 4 is formed on the section thereof 4 in contact with the anal, and a pressure sensitive adhesive surface 6 having a pressure sensitive adhesive is formed around the slit 5, thereby ensuring stool to be properly taken from the slit 5 into the bag 4. In this case, a section other than the bag 4 is not required to have waterproofing quality and, therefore, the manufacture of the diaper by use of a material having touch and gas permeability like an ordinary undershirt is preferable.  Also, a water absorptive polymeric material may be put in the bag for urine.

Title: Hot air heater and dust collector
Inventor: TAKAI MITSUO
IPC: F24H9/02
Filed: 1988-11-09
Abstract: PURPOSE:To improve hot air performance and prevent rise in the temperature of floor surface by placing a hot air blowout port above an open air suction port in two stages. CONSTITUTION:Open air is sucked up from an open air suction port 12 in the lower part of a front panel 10 and flows inside a suction air duct 17, passing through a filter 23 where the air is pressurized by a fan 14, and it is heated by a heating element 18 inside a discharge air duct 16. The heated air is expand ed horizontally along the cross sectional configuration of the discharge air duct 16 and discharged from a hot air blowout port 11 on the upper part of the front panel 10. As a result, a low temperature open air current flowing toward the open air suction port 12 is generated on the floor surface in front of the front panel 10. The hot air discharged from the hot air blowout port 11 flows on the cold open air current and rises due to a differential temperature against the open air, which prevents the hot air from direct contact against the floor surface. Therefore, this construction eliminates the generation of any possible problem even when a low thermal resistant floor material is used.

Title: Hydraulic coupling
Inventor: SUZUKI YASUYUKI
IPC: F16D25/0638
Filed: 1988-11-09
Abstract: PURPOSE:To suppress shock in engagement by providing a hydraulic damper, suppressing the movement speed of a piston in the direction that both clutch plates are engaged between one side transmitting member and a piston. CONSTITUTION:When pressurized oil is supplied to a hydraulic oil chamber 13, a piston 5 is forced to the left against a spring 18. Although the volume of a damping chamber 25 is expanded by the movement of the piston 5, a check valve 27 stops the flow of hydraulic oil from the hydraulic oil chamber 13 to the damping chamber 25, and a small amount of hydraulic oil flows into the damping chamber 25 through a clearance between a damper piston 26 and a fitting hole 29 to suppress the movement speed of the piston 5 according to that amount of hydraulic oil. Accordingly, clutch plates 4 are pressed between a pressing plate 16, an input side clutch plate 3 and a pressure receiving plate 11 and engaged gently by frictional force to avoid shock generated in engagement.

Filed: 1987-11-09
Abstract: PURPOSE:To obtain an optical switch which is operated by total reflection without depending on polarized light by providing intersected light guides and reflecting parts on the center line of the intersected part on a semiconductor substrate and forming the reflecting parts of two multiple quantum well structures having different layer thicknesses. CONSTITUTION:The intersected light guides 10 and the reflecting parts 3 on the center line of the intersected parts are provided on the semiconductor substrate 1. Light having parallel polarized light TE and perpendicularly polarized light TM components is advanced straightly and is emitted if said light enters the light guides 10 and when an electric field is not impressed to the MQW reflecting parts 3 of the multiple quantum well structures. The TE component receives the decrease of refractive index in the MQW reflecting part of a well thickness 90Angstrom  and the TM component receives said decrease in the MQW reflecting part of a well thickness 110Angstrom when the electric filed is impressed to said parts. Both the components are then totally reflected and are emitted from the light guides 10 on the opposite side. The intersection type optical switch using the total reflection without depending on the polarized light is realized by changing the well thicknesses in such a manner.
