Title: Hyperthermia apparatus
Inventor: HATTA SHINJI
IPC: A61N5/02
Filed: 1988-07-06
Abstract: PURPOSE:To always control the title apparatus at the min. reflectivity point while a power value is obtained on the basis of scala by mounting a power measuring means, a means for calculating the reflectivity of load on the basis of the output of the power measuring means at each value while the matching constant of a matching means is made variable, a means for storing the reflectivity and a means for determining the matching constant of the matching means. CONSTITUTION:The matching constant of a matching circuit 3 is once swept over an entire range and the reflectivity of a load circuit 4 at the time of each value is once stored in a memory circuit 7 and the value of the matching constant lowest in reflectivity can be detected on the basis of the stored data. Therefore, the min. point of reflectivity can be calculated while a power value is obtained on the basis of scalar. Further, since the tracking of the min. point is performed within a real time after the min. point is searched, the min. point where tracking is performed becomes the min. point of reflectivity so far as the impedance ¦z¦ of the load circuit 4 is not suddenly changed during heating. Actually, it is regarded that the impedance of the load circuit 4 is not changed. Therefore, the load circuit 4 can be always operated at the min. point of reflectivity.

Title: Combustion control circuit
Inventor: MAEHARA NAOYOSHI
IPC: F23N5/00
Filed: 1983-09-09
Abstract: PURPOSE:To enable a free setting of a combustion termination point so as to restrict against a reduction of concentration in oxygen in atmosphere by a method wherein outputs from two circuits in which flame current is changed with voltage are compared with each other and a feeding amount of fuel is controlled and at the same time a subtraction circuit is arranged in one of the circuits. CONSTITUTION:Flame currents If1 and If2 flowing in flame rods 14 and 15 through a flame 12 are passed through voltage conversion circuits 19 and 20 so as to generate output voltages e1 and e2 corresponding to the electric current of the flame current. The output voltages are compared to each other in a comparator 24 at a combustion control part 23 for their values so as to control a control means 26 for use in controlling a feeding volume of fuel by a driving part 25. When the burner 11 is operated to perform a combustion in atmosphere of low oxygen concentration, If1 and If2 are crossed at the point Q. The output e2 becomes an output level corresponding to If'2 (=If2-If) by adding the subtraction circuit 27 to a voltage convertor 20, and the outputs e1 and e2 become the similar voltage volue at the point Q'. Due to this fact, a mere application of a simple comparator 24 causes the combustion to be stopped or the calory of combustion to be decreased, resulting in that an incomplete combustion can be prevented.

Title: Electrostrictive element type pressure control valve
Inventor: KASHIMA MITSUHIRO
IPC: F16K31/42
Filed: 1989-06-29
Abstract: PURPOSE:To control fluid pressure variably with good responsiveness by providing a main valve for changing the flow sectional area of a fluid in response to pilot pressure and a pilot valve for controlling this pilot pressure through an electrostrictive element deformed corresponding to current application from outside. CONSTITUTION:When a current is applied to an electrostrictive element 11, a gap between a pilot valve 3 and a spool guide 5 is closed, so that the outflow of operating oil from an oil chamber 10 is impeded, and the pressure in the oil chamber 10 and a passage 7 becomes equal. The spool 4 of a spool valve 2 (a main valve) thereby starts its sliding motion against a spring 9 as soon as the pressure of the passage 7 starts rising, so that the operating oil in the passage 7 flows out toward an outflow port 8 through the communication between an opening part 4A and the opening part 6A of a rod 6. When the current applied to the element 11 is put on and off periodically, the valve 3 is maintained to the opening corresponding to the on-off duty ratio between the fully closed and fully opened positions, as well as the pressure rise of the passage 7 is suppressed at the above-mentioned duty ratio.

Inventor: ANDO KAZUMASA
IPC: H01L21/822
Filed: 1994-07-20
Abstract: PURPOSE:To provide a semiconductor device which restrains the influence upon the characteristics change of a semiconductor device to a minimum and improves the level of integration by facilitating reduction of the layout area of resistance elements with irregularity of resistance value kept restrained 4 to be small. CONSTITUTION:A resistance element 7 is constituted by burying a resistor 4 composed of polycrystalline semiconductor having a desired resistance value, in a vertical trench 2 of a substrate 1 composed of a semiconductor substrate, interposing an insulating film 3. The resistor 4 has a resistance width W in the vertical direction V of the substrate 1, and a resistance length L in the horizontal direction H of the substrate 1, and is doped with impurities. By setting the resistance width W large in the vertical direction V, a desired resistance value can be obtained while the resistance length L in the horizontal direction H is small. Thereby the layout area of the resistance element 7 is easily reduced. Since a desired resistance value is obtained by adjusting the dosage of impurities, irregurality of the resistance value can be restrained in a small range.

Filed: 1993-07-07
Abstract: PURPOSE:To improve manufacturing yield of an LSI by detecting defective circuit elements before wiring formation and forming a wiring pattern so as to evade the detective elements. CONSTITUTION:The emitter region 8 of a transistor is exposed by selectively eliminating an insulating film 9 covering circuit elements. An anodic oxide film 11 is formed only on the emitter region 8A of a defective transistor A. A metal film (first layer wiring 12) is formed on the emitter regions 8B, 8C of normal transistors B, C by a selective CVD method. The position of the defective transistor A is specified by detecting whether the metal film is present. On the basis of the result, a wiring pattern is designed and a wiring is formed. Thereby the number of defective LSI's is reduced, and the yield is improved. By adopting a foreign matter inspection method using laser scattered light for the inspection of detecting defective circuit elements, the decrease of throughput can be restrained to a minimum.

Title: Helix type waveguide
Inventor: HASHIMOTO HIROYUKI
IPC: H01J23/26
Filed: 1979-12-24
Abstract: PURPOSE:To disperse the heat produced by a helix effectively, by jointing the contact faces of a helix supporting rod and a tubular casing thereby sufficiently lowering the heat resistance produced between them. CONSTITUTION:When jointing the contact faces of a helix supporting rod 2 and a tubular casing 3, the heat produced by a helix 1 is transmitted to the supporting rod 2 then through a metalized layer 4 to a casing 3 where it is dispersed. Since the supporting rod 2 and the outer casing 3 are jointed while utilizing the dispersion of metal, the cleanliness of the joint face is improved and the relation between the optimal temperature and the pressure is selected. A metal having the eutectic point is selected as the material for the metallized layer 4 provided on the supporting rod 2 and for the outer casing 3. Consequently high frequency and high power are realized resulting in the considerable improvement of the reliability.

Title: Bearing mechanism
Inventor: ENOMOTO JUN
IPC: F16C25/04
Filed: 1998-06-16
Abstract: PROBLEM TO BE SOLVED: To prevent a remarkable change in magnitude of generated torque even if a bush is expanded or contracted due to a change of atmosphere temperature by providing a spring means for pressing a contact part abutting againt the end face of a rotor to the end face of the rotor to generate designated frictional force. SOLUTION: A shaft 13 is capable of relatively moving in the axial direction and in the rotating direction to a bush 2, and it is kept from being moved in the axial direction by its dead load even if a contact part 5 is pressed to one axial end face 13b of a shaft 13 by the elasticity of a plate spring 6. During the rotation of the shaft 13, frictional resistance or sliding resistance of designated magnitude is generated between the contact part 5 and one axial end face 13b of the shaft 13 and torque is generated in the shaft 13. Even if the bush 2 made of resin is expanded or contracted in the radial direction due to a change of atmosphere temperature, the sliding status will not be changed.  Accordingly, the generated frictional resistance or sliding resistance little change in its magnitude, and the magnitude of torque generated in the shaft 13 little changes so as to stabilize the magnitude of generated torque.
