Title: Radiation detector
Inventor: AISAKA TATSUYOSHI
IPC: A61B6/03
Filed: 1984-02-15
Abstract: PURPOSE:To improve the shock resistance of a mixed fiber resin layer by providing an aramide fiber layer at the X-ray incidence side of the mixed fiber resin layer which form an X-ray incidence window. CONSTITUTION:The radiation detector 2 is equipped with an arcuate box body 4, which has the X-ray incidence window made of a carbon fiber resin layer 4a. If the carbon fiber resin layer 4a damages or breaks owing to the high-pressure gas, etc., in the box 4, the aramide fiber resin layer 4b functions as a protection layer. Specially, the aramide fiber resin layer 4b can be laminated on the carbon fiber resin layer 4a, but a gas layer is formed between the both to functions as a buffer layer, which is more effective in terms of safety.

Inventor: HIROSHIMA KOICHI
IPC: G03G15/16
Filed: 1996-02-13
Abstract: PROBLEM TO BE SOLVED: To prevent a transfer going-through phenomenon and also to obtain an improved transfer performance and an improved separation performance, by obtaining a two-color cast-molded transfer belt by a centrifugal molding device and providing a base layer formed of low-resistance elastomer and a surface layer of high-resistance elastomer laminated on the surface of the base layer. SOLUTION: In order to prevent a transfer voltage from becoming too high, the resistance of the transfer belt is reduced as the whole, and the surface layer 21 is made thinner by introducing a two-layer constitution and the resistance ratio of the layer 21 to the base layer 22 is increased. Besides, the whole transfer belt is constituted of the elastomer so that mechanical characteristics such as bending characteristics, tensile strength characteristics, etc., may be satisfied, then, the transfer belt is made thoroughly durable for a long use without causing meandering and biasing, etc., in a state where the tension is applied on the transfer belt by a transfer roller and a driving roller.  And also, in the case of molding the belt by the centrifugal device, material for the surface layer 21 is inserted in the mold once, after hardening the material, material for the lower layer 22 is inserted into the mold, then, hardened. At this time, both materials for the surface layer 21 and the lower layer 22 whose hardness temperature are largely different from each other are not suitable for using.

Title: Manufacture of v block for v belt
Inventor: UCHIYAMA MITSUO
IPC: F16G5/16
Filed: 1987-02-06
Abstract: PURPOSE:To shorten a working time by forming a curved face bulging at the center on at least one part of the recessed groove face of a block or the abutting face of a pulley by compressing by a die the thickness direction of a V block after working its shape by punching. CONSTITUTION:The V block 1' subjected to a punching is compressed in the thickness direction by arranging it between an upper die 4 and lower die 5 at the interval to the extent of not bringing into contact with each other. The surfaces of the upper die and lower die 4, 5 coming into contact with the stock 1' are taken of the material having a high friction coefft. or in the shape providing a small uneven face. In the case, therefore, of the stock 1' being subjected to a compression deformation by receiving a compression in the thickness direction between the upper and lower dies 4, 5, the elongation of upper and lower contact faces is extremely restrained, intending to extend in the direction at right angles with the thickness direction and a center bulging curved face is formed in the thickness direction. By doing like this, the working time is drastically shortened and at the same time a center bulging curved face can be formed n the abutting face on the pulley effecting a big influence on the durability of the V block as well.

Title: Ultrasonic flowmeter
Inventor: SHIMIZU KAZUYOSHI
IPC: G01F1/66
Filed: 1997-01-24
Abstract: PROBLEM TO BE SOLVED: To improve measurement accuracy of an ultrasonic flowmeter. SOLUTION: Under the control by a CPU 4a, a flow velocity-measuring part 1 obtains a linear flow velocity on the basis of a propagation time of ultrasonic waves between a pair of wave transmitters.receivers faced to each other in a pipe body where a fluid circulates. After the linear average flow velocity is corrected with a pressure data 201 and a temperature data 202, a sectional average flow velocity which is necessary for the calculation of a flow rate is obtained. A product of the sectional average flow velocity and a sectional area is the flow rate. A correction to a change corresponding to a flow velocity is made at a flow velocity distribution correction amount table 5 as a correction coefficient required for a conversion carried out when the sectional average flow velocity is obtained.  Moreover, an instrumental error correction is made at an instrumental error correction amount table 6.

Filed: 1992-01-16
Abstract: PURPOSE:To improve an operation panel in operability and maintainability by providing a supporting member rotatably supporting a panel cover and a holding member holding the panel cover in the rotated position. CONSTITUTION:When a panel cover 2 is brought to a stop in a position where an operation part 1 is easy to see by an operator, the panel cover 2 is held in the position by the reaction of a damper 4.

When the operation part 1 is removed from the panel cover 2 at the time of maintenance, a screw 9 can be easily removed from the rear of the panel cover 2 by pulling the panel cover 2 to the maximum position allowed by the damper 4. In this manner, the maintenance operation of the operation panel 1 can be conducted in the state that the operation part 1 is removed from the panel cover 2. In addition, by pulling a knob part 8 of the panel cover 2, the panel cover 2 rotates in a direction shown by an arrow A about a hinge 3 as a fulcrum.

Title: Stage of wafer prober
Inventor: KOBIKI MICHIHIRO
IPC: H01J37/20
Filed: 1990-02-05
Abstract: PURPOSE:To restrain temperature rise of all chips in a wafer, and estimate electric characteristics under thermally uniform conditions, by constituting a stage, on which a wafer is mounted, of a porous metal material obtained by compression-molding metal fine particles or fiber type metal. CONSTITUTION:The stage 8b of an on-wafer prober is constituted by using porous material obtained by compression-molding fine powder composed of high thermal conductivity metal or fiber type metal. That is, when fine alloy powder metal like CuSn several mum in diameter of fiber type metal is used, the thermal conductivity is higher than that of the wafer stage made of stainless by a factor of about ten, and the stage 8b is excellent in thermal dissipation. Since said material is porous, the wafer 4 can be fixed by vacuum sucking. Thereby troubles such as abnormal temperature rise, unstableness of contact, and cracks of a wafer can be avoided at the time of estimating electric characteristics of each chip 6, and accurate estimation is enabled because about ten times high heat dissipating effect can be obtained as compared with conventional strainless material.

IPC: B23H1/02
Filed: 1978-03-09
Abstract: PURPOSE:To control processing average current by controlling interruption intervals by maintaining the pulse width and interval fixed without controlling them, in electric discharge processing. CONSTITUTION:A processing gap is formed between processing electrode 1 and work 2. Processing power is supplied from power supply 3 to the processing gap via switch 4, made of a transistor. By turning switch 4 on and off, pulses are given to the gap. The pulse width and interval are fixed at certain values, and a fixed train of pulses is generated. By the pulse generated by oscillator 6, a unit pulse train is interrupted and controlled, and when a time-width pulse train is generated, there is an interval of rest time, to be followed by a pulse train again. Thus,  processing is operated in the processing gap.
