Title: Optical ic sensor
Inventor: OOTE AKIRA
IPC: G01J9/00
Filed: 1983-06-07
Abstract: PURPOSE:To obtain an inexpensive optical IC sensor which is handled easily by coupling one optical fiber with an optical IC element and coupling a light source and a photodetector with the other terminal of the optical fiber optically. CONSTITUTION:The optical IC element 3 has the 1st and the 2nd optical waveguides 31 and 32 and is provided with reflecting plates 34 at the other terminal of each waveguide. Light from a light source 1 is guided to the 1st and the 2nd optical waveguides 31 and 32 of the optical IC element 3 through the optical waveguide 51 of an optical demultiplexing and multiplexing element 5 and the optical fiber 2. The light beams guided to the other-side terminals of the waveguides 31 and 32 are reflected by the reflecting plates 34 to return through the same waveguides 31 and 32, and interfere with each other at one optical waveguide to be transmitted to the photodetector 4. The intensity P of the signal light detected by the photodetector 4 corresponds to the difference in optical length or refractive index between the optical waveguides 31 and 32, and a physical quantity to be measured is known from the intensity. Thus, the inexpensive optical IC sensor which is handled easily is obtained.

Title: Field electron emitter and its manufacture
Inventor: KONDO YUKIHIRO
IPC: H01J9/02
Filed: 1996-04-23
Abstract: PROBLEM TO BE SOLVED: To provide a field electron emitter whose life is prolonged. SOLUTION: An emitter 5 is deposited over a substrate via a resistor layer. A gate electrode is deposited over the substrate via an insulating layer, and is opposed to the emitter 5 via a predetermined recess serving as an electron emission space. The emitter 5 has four pointed ends 5a that project in the direction of a plane, the angles of the pointed ends 5a being of three kinds, e.g. 45, 30, and 15 degrees. Since plural kinds of emitters 5 with different voltage-current characteristics are formed by forming plural kinds of pointed ends 5a with different angles, even if some of the emitters are damaged when the applied voltage increases as the emitters deteriorate, the emission currents of the remaining emitters increase and compensate them, thereby holding the emission currents roughly constant as a whole.

Title: Screw compressor
Inventor: MATSUI AKIRA
IPC: F04C18/16
Filed: 1990-04-18
Abstract: PURPOSE:To make automatic control over the regulation of an internal volumetric ratio Vi performable in a simple structure by installing a lifting internal volumetric ratio Vi regula tor valve and a control valve formed for making a passage selectable, respectively, and making them so as to produce a state of the internal volumetric ratio Vi suited to discharge pressure during operation of a compressor and pressure just before discharge without any operation from the outside. CONSTITUTION:Gas of suction pressure Ps is sucked from an inlet port 1 and compressed by a screw rotor 4 in rotation, and then is discharged to a discharge passage 13 of discharge pressure Pd from a discharge port 3 by way of a discharge port 2. In addition, a first chamber 23 of a control valve 21 to be connected to a discharge adjacent space comes to discharge adjacent pressure Po and a second chamber 24 to be interconnected to the discharge passage 13 to the discharge pressure Pd, respectively. When it is set by Po>Pd, a valve stem 28 is moved to the side of a passage 16 together with a diaphragm 22, and a valve element 27 opens this passage 16. On the other hand, since pressure almost equal to the discharge pressure Pd acts on one end 12 of an internal volumetric ratio Vi regulator valve 7 when it is in a moving limit at the rotor side, this Vi regulator valve 7 is shifted to the counter- rotor side. In consequence, the suction side of the discharge port 2 comes to a B position, thus the internal volumetic ratio Vi is minimized.

Title: Control device for air motor for starting internal-conbustion engine
Inventor: TANAKA MASAMI
IPC: F02N7/08
Filed: 1983-06-07
Abstract: PURPOSE:To smooth the meshing of a pinion and a ring gear and prevent the impact breakage of the device by a method wherein a driving shaft, rotating in a low speed through a special screw spline, is pushed and advanced by a piston to slow down the rotation thereof. CONSTITUTION:When a start valve is opened and the compressed air from an air tank is distributed to two routes through an air control valve, the air, distributed to one port, enters into the operating chamber 35 of the main body 6 of the air motor and slides the piston 33 into the jump-out direction of the piston 8. On the other hand, the air, choked by the other port and flowed out therethrough, enters into a cylinder 11 to rotate a rotor 12 at a low speed. According to these operations, the driving shaft 30 is rotated through gears 23, 22, a tubular body 24 and a screw spline 29 but is tried to rotate reversely by the advancement of the piston 33 through the screw spline 29, therefore, the rotation of the pinion 8 becomes slow. Then, the pinion 8 is meshed with the ring gear smoothly. Thereafter, the rotor 12 is rotated at a high speed.

Title: Automatic selector valve
Inventor: TAKAHASHI TOSHINAO
IPC: B01D29/60
Filed: 1985-05-16
Abstract: PURPOSE:To permit the smooth switching from the reverse washing position to the filtering position by fixing a subvalve body for opening and closing the through hole inlet of a valve body onto a reciprocating shaft and reducing the closing surface of the subvalve body smaller than the pressure receiving surface on the opposite side. CONSTITUTION:A through hole 14A formed at the center part of a valve body 8 is fixed onto a subvalve body 12 in filtering and water-sealed. The pressure receiving area of the subvalve body 12 at this time is small, and the necessary force for opening the through hole 14A is enough small. While, the force for pressing the valve V' side subvalve body 12' having a large pressure receiving area is larger than the force for closing the through hole 14A, and the through hole 14A can be opened easily. When the subvalve body 12 is opened, the water pressure in the reverse direction acts also onto the right surface of the valve body 8, and the force acting in the direction for closing the valve body 8 is reduced.
