Title: Member strength inspecting method
Inventor: SATO TAKAHARU
IPC: G01N3/60
Filed: 1996-07-23
Abstract: PROBLEM TO BE SOLVED: To enable compressive stress and tensile stress to be freely given to an optional position of a member with a simple operation by using a jig of the quality of material having the coefficient of thermal expansion different from the member to heat or cool the jig fitting loose on the member. SOLUTION: A jig is shaped such that one of the jig and a member fit loose on the other, while the quality of material of the jig is selected to have the coefficient of thermal expansion different from the member. When the jig and member are heated or cooled according to the loose fitting relationship between the jig and member, a difference between the coefficients of thermal expansion of both applies a predetermined compressive or tensile stress to the member to enable the inspection of the member strength while enabling the measurement of the stress or strain of a hard member. For example, the member 2 has two projection parts 21, 22. A rod-like jig 5 is loose fitted between these two projection parts 21, 22 to be heated and cooled, so that the tensile stress can be given to the root parts of the two projection parts 21, 22 of the member 2.

Title: Optical temperature sensor
Inventor: SUEHIRO YOSHIKAZU
IPC: G01K11/12
Filed: 1987-08-26
Abstract: PURPOSE:To discriminate which optical sensor exceeds set temperature when plural optical sensors are connected in series by arranging an optical demultiplexer and an optical multiplexer at the light incidence and projection parts of a heat sensing part and providing an optical path which connects them with each other. CONSTITUTION:Light incident on the light incidence end 5 of this sensor main body 1 enters the optical demultiplexer 3. When light from an LED light source is used as this light, the light is distributed in a wavelength range within a certain range. The light is therefore split by an interference film filter 14 into light power of optical paths 10 and 11, and the heat sensing part 2 is provided in one of them. Then split light passes through the optical multiplexer 4 and is projected from the light projection terminal 6. At this time, when the ambient temperature of the heat sensing part 2 exceeds the set temperature, a cut off state is set between the optical paths 10 and 12 and the projection light power decreases correspondingly. Thus, even when the temperature of a temperature sensing point exceeds the set value, the optical paths do not enter a complete cutoff state and interference filters 14 and 15 of the demultiplexer 3 and multiplexer 4 are set to proper characteristics, thereby detecting which sensor operates on an optical power monitor.

Title: Electrodeless discharge lamp lighting device
Inventor: KUMAGAI YUJI
IPC: H05B41/24
Filed: 1999-07-27
Abstract: PROBLEM TO BE SOLVED: To correctly discriminate and control based on the discrimination by controlling an overshoot discriminated with the both end voltages of an induction coil in the vicinity of an electrodeless discharge lamp and input current of a high frequency power source to which DC voltage is applied from a DC power source, according to each state of stable lighting and no load with a control circuit. SOLUTION: Output signals of IC1 and IC2 producing an Hi signal by rising of voltage of resistor Rs according to increase in input current of a high frequency power source 4 and substantial rising of both end voltages of an induction coil 3 are inputted in a control circuit 7 and outputted from output parts 1, 2. When an overshoot is generated in starting, the Hi signal from the output part 1 lowers both end voltages of a voltage dividing variable resistor VR, and a step-up chopper control circuit 5a decreases input current of the high frequency power source 4 to keep lighting. In no load, the output part 2 also outputs the Hi signal, intermittently oscillates a switching element within the high frequency power source 4 to keep starting voltage, and stress of the constituting elements is lowered. In a normal state, the IC1 and the IC2 become low, and a discharge lamp is stably lit.

Filed: 1987-08-28
Abstract: PURPOSE:To make it possible to measure the flow rate of a high pressure fluid and to measure electric conductivity, by arranging a nonmetallic tube having electrodes and a fluid pressure transfer part in a metallic pressure resisting outer tube in series, and sealing a pressure transfer medium in a space between the outer tube and the inner tube. CONSTITUTION:A pressure resisting outer tube 1 is a metal tube. Protruding parts 1b are formed at specified two places on the inner surface of the tube 1. A plurality of pressure transfer paths, which penetrate the tube in the axial direction of the pipe, are formed at each protruding part. A nonmetallic inner tube 2 is held with the protruding parts 1b so that a gap 16 is provided between the inner wall of the outer tube and the inner tube in a concentric pattern in the outer tube 1. A pair of electrodes 6 are provided at the tube wall at the center in an axially symmetric pattern of the tube. Irregular bellows 11 are fluid pressure transfer parts 3, which are bonded to the outer tube 1 and the inner tube 2 so that a gap 17 is formed between the out inner wall of the outer tube and the parts 3. A pressure transfer medium 12 is sealed in the gaps 16 and 17 and the pressure transfer paths. In such a structure, sufficient mechanical strength can be readily provided in the outer tube. Tensile stress in the circumferential direction is not applied to the nonmetallic inner tube 2. Therefore, the inner diameter of the tube is not changed. The interval between the electrodes is not changed. Thus, measuring accuracy can be maintained.

Inventor: GLOVER EDWARD C T S
IPC: B65D47/28
Filed: 1997-08-07
Abstract: PROBLEM TO BE SOLVED: To prevent liquid leakage while a container is changed by providing a movable tube inserted in a hole part of a lid through a seal, and closing a hole in a tube wall part by the seal when the tube is pulled out through the seal until further pull-out is prevented.

Title: Beam current control method for ecr ion source-mounted ion implanter
Inventor: KONISHI MASASHI
IPC: H01J37/317
Filed: 1992-07-20
Abstract: PURPOSE:To stably maintain a beam current at the desired preset value. CONSTITUTION:When a beam current Ib is to be set to a new value, the output Wm of a microwave power source 5 is changed within the preset range from the present operation value, and the change of the microwave output is stopped when the actual value of the beam current Ib by a beam monitor 12 exceeds the preset value. The control speed is changed in response to the difference between the preset value of the beam monitor current and the actual value to increase or decrease the microwave output so that the beam monitor current reaches the vicinity of the preset value. The value of the extracting power source current Ie at this time is used as the preset value of the current thereafter, and the microwave output is controlled so that the value of the actual extracting power source current coincides with the preset value. The beam current Ib can be stably maintained at the desired value.
