Title: Control device for hydraulic machine
Inventor: OGUMA AKASHI
IPC: F03B15/18
Filed: 1988-06-02
Abstract: PURPOSE:To make it possible to loosely close a guide vane even when any accident occurs by specifying the shape of cams of a cam mechanism switching a loosely closed pressure control device in accordance with the position of a servo-motor, and attaching limit switches for detecting the over-gate position of the guide vane. CONSTITUTION:When a wire rope 5 feeding back the amount of operation of a servo-motor 1 to a governor actuator 17 is cut, a return shaft 7 reaches the over-gate position by the dead load of a weighty 15, and as a result, a converter 2 and a control piston 26 are lowered by a governor regulator 16 received a totally closing signal from a differential transformer 29 to supply pressurized oil to a closed side port 22 of the servomotor 1 through a pressure control valve 3. A loosely closed pressure control device 12 is then switched by a cam 9, and a loosely closing valve 11 is also switched to a loosely closed state. Because one of plural cams 24 attached to a shaft 56 of a spur gear 23 actuates a limit switch 25, a water turbine is emergency-stopped.

Title: Mute mechanism of upright type piano
Inventor: KAWAMURA KIYOSHI
IPC: G10C3/00
Filed: 1977-11-12
Abstract: PURPOSE: To reduce the number of the strings striken by hammers by moving a frame assembly together with damper mechanisms in a transverse direction by way of pedal mechanism.  
     CONSTITUTION: When a pedal 43 is treaded, a frame 6 is parallel moved in a transverse direction by way of the roller followers 55, 56 of an actuating rod 47. This causes the damper mechanism provided in the frame 6 to move, thereby deviating the string dividing pitch P and action deviding pitch Q and reducing the number of the strings to be striken by a hammer 71. Hence, even in an upright type piano, weak tones similar to those of a grand piano may be produced without changing of timbre, touch feeling.

Title: Oil pressure control valve
Inventor: KUBOTA HITOSHI
IPC: B60T8/28
Filed: 1978-11-06
Abstract: PURPOSE: To obtain a brake characteristic having good distribution by making the inclination changeable during the changing of car weight after split point, while making settable a plurality of points in accordance with the car weight.  
     CONSTITUTION: At max. load the piston 26 is urged maximum against the spring 28 to obtain max. sealing pressure. Consequently the lever 8 is rotated counter- clockwise and the setting loads of both springs 12, 12' are reversed such that the setting load of spring 12 is greater than that of spring 12', while when the oil pressure PM of master cylinder exceeds over crytical oil pressure corresponding with the split point, valve P5 limits the increase of oil pressure PF for braking the front wheel through proportioning operation and when PM increases further P valve 6 also functions to limit the increase of oil pressure PR for braking the rear wheel thereby the oil control valve approximates the oil pressure distributing characteristics for braking the front and rear wheels to ideal one.

Title: Field effect semiconductor device
Inventor: HARA NAOKI
IPC: H01L21/338
Filed: 1998-05-19
Abstract: PROBLEM TO BE SOLVED: To increase the reverse breakdown voltage and a maximum drain current by providing a recess between a cap layer and a drain electrode, at least one the side of the drain so that the recess can isolate the cap layer surrounding a gate electrode from the drain electrode. SOLUTION: The forbidden band width of a semiconductor constituting a channel layer 2 is made larger than that of a semiconductor constituting a cap layer 3. Furthermore, a recess 9 is formed in the layer 3 by completely removing at least an end portion of the layer 3 region that is converted into a heavily-doped region for constituting a drain region 5, the end portion being on the side of a gate electrode 4. As a result, a drain electrode 6 is not directly connected to the undoped layer 3, so that a leak current path can be eliminated, thereby realizing a high reverse breakdown voltage. Furthermore, since a low resistance region that is the heavily-doped region which is converted from the layer 3 is interposed between the electrode 6 and a channel region of the layer 2, parasitic resistances attributed to crosswise resistances can be prevented from increasing, thereby a maximum drain current can be increased.

Title: Photocatalyst for treatment of harmful substance and device for treating harmful substance
Inventor: MASUDA RYUJI
IPC: B01J21/06
Filed: 1993-05-15
Abstract: PURPOSE:To obtain a photocatalyst for treatment of a harmful substance having high efficiency and easy to handle by dipping a woven fabric of glass fibers in a soln. prepd. by dissolving a precursor of titanium oxide and an org. resin, drying the fabric and forming an Si-O-Ti bonded layer by firing between each of the glass fibers and the resulting titanium oxide. CONSTITUTION:A woven fabric of glass fibers A is dipped in a soln. prepd. by dissolving a precursor convertible into titanium oxide by heating and an org. resin in compatible solvents, the fabric is dried and an Si-O-Ti bonded layer C is formed by firing between each of the glass fibers A and the resulting thin titanium oxide film B coating the fabric to obtain the objective photocatalyst for treatment of a harmful substance. In this case, a dehydration condensation reaction proceeds and the Si-O-Ti bonded layer C is formed at a relatively low temp. because only the surface of the fabric is locally heated by the heat of combustion generated by an oxidation degradation reaction of the org. resin and that of org. residues constituting the precursor. By the presence of the layer C, a decomposition reaction of a harmful substance is accelerated.

Title: Switching system for recording and reproduction
Inventor: NAKAGAWA SHIROU
IPC: G11B5/027
Filed: 1979-10-25
Abstract: PURPOSE:To switch recording and reproduction simply in excellent manner while connecting recording and reproducing amplifiers to a head in common use for recording and reproduction, by blocking a fine signal with a nonlinear element and switching an FET through the control of the potential of source. CONSTITUTION:When a switch 8 is connected to a contact 9, the first stage N type FETS of a reproducing amplfier 2 is cut off because the source is at high potential to avoid a recording signal from being flowed to the amplifier, which is fed to a head 1 in common use for recording and reproduction via a nonlinear element that blocks a weak signal in antiparallel connection of diodes d1, d2. When the switch 8 is connected to a contact 10, an FET5 is conductive to apply the reproduction signal from the head 1 to the amplifier 2, and weak reproduction signal and noise interrupted at the element 6 do not flow to a recording amplifer. Accordingly, the switching of recording and reproduction can simply be made in excellent manner, while connecting the recording and reproducing amplifiers to the head in common use for recording and reproduction.
