Title: Joining method for laminated plate
Inventor: SASAKI NAOKI
IPC: B23K11/16
Filed: 1985-04-30
Abstract: PURPOSE:To make possible the easy resistance welding of a laminated plate and metallic plate without melting the resin layer of the laminated plate by raising a flange by burring to the metallic plate to be joined to the laminated plate, inserting the flange into the aperture opened to the laminated plate then welding the two plates. CONSTITUTION:The metallic plate 3 is welded to the laminated plate 1 formed by interposing the resin layer 1c between metallic plates 1a and 1b in this method. The cylindrical flange 31 is formed by burring near the edge end of the plate 3 after boring of a prepd. hole. On the other hand, the aperture 11 through which the flange 31 can pass is bored near the end edge of the plate 1. The plate 1 and the plate 3 are superposed and after the flange 31 is inserted into the aperture 11, an electrode rod 5a for welding is pressed to the surface of the plate 1a of the plate 1. The other electrode rod 5b is pressed to the flange 31 and electricity is conducted between the rods 5a and 5b to weld the two plates through the contact part between the inside circumferential wall 13 of the plate 1a and the outside circumferential wall 33 of the flange 31.

Title: Oscillation indicator
Inventor: SEKINE TOSHIRO
IPC: G01M99/00
Filed: 1991-03-29
Abstract: PURPOSE:To provide an oscillation indicator which can accurately and quickly indicates the amplitude in a digital form. CONSTITUTION:The output of an oscillation detector 40 is supplied to an amplifier, the amplified output is then supplied to an analog/digital converter, and furthermore, the converted output is supplied to a microcomputer 45. In the microcomputer 45, the drive frequency of an oscillator on which an oscillation detector 40 is installed, is detected based on the output of the analog/digital converter, comparison of the aforesaid frequency with frequency set in the microcomputer is made based on the result of detection, or the gain of the amplifier is controlled by a some function unit in response to the output frequency of the converter. When an acceleration type detector is used as the oscillation detector in a low and a high frequency range, its output is thereby increased in proportion to amplitude X (frequency)<2>, if the gain of the amplifier remains equal in both the low and high frequency ranges, the output of the amplifier is small in the low frequency range, but is large in the high frequency range, the amplitude of the same oscillator can therefore be measured roughly in a full scale at all times regardless of the frequency of the oscillator.

Title: Inspection device for piping and casing
Inventor: SUGANO SATOSHI
IPC: G01B15/02
Filed: 1987-04-17
Abstract: PURPOSE:To enable the specifying of a position and a range of generated reduction in thickness, by measuring intensity of radiation along the outer surface of a piping or the like with a radiation sensor. CONSTITUTION:In a piping or the like made of a material which is liable to form a radioactive clad having a radioactive substance contained in a fluid adhering to the inner wall of a member, the radioactive clad is peeled off at a position where reduction in thickness occurs in the inner wall so that intensity of radiation as measured from the outer surface of the piping becomes less than that of the position where no such a reduction occurs. On the other hand, in a piping made of a material that could make a radioactive substance contained in the fluid hard to adhere to the inner wall of the member and prevent the formation of a radioactive clad, a piping through which the fluid containing radioactive substance passes or the like temporarily, intensity of radiation enhanced at the position with a reduced thickness as compared to the position without such a reduced thickness. Thus, a sensor for detecting radiation is used to measure a distribution of intensity of radiation along the outer surface of the piping or the like, thereby simplifying detection on where a reduction in thickness occurs.

Title: Easily sharpened scissors
Inventor: MATANO MITSURU
IPC: B26B13/00
Filed: 1999-02-23
Abstract: PROBLEM TO BE SOLVED: To easily and reliably polish both blades in a closed sate of scissors by forming edges of both blades in a shape positioned on the same line as a mating blade shoulder in a nipped-off and closed state of opposed both blades of general clipping scissors. SOLUTION: In general clipping scissors and pruning scissors, since the cross- sectional shape of a nipped-off and closed state of both blades becomes an L shape, the edge cannot be sharpened in the most easily handled, nipped-off and closed state. To cope with this, the edges of both blades are formed in a shape positioned on the same line as a mating blade shoulder in a nipped-off and closed state of both blades. According to this, since a sharpening surface of both blades becomes the same line, the sharpening surface can be easily and reliably polished. The edge of the scissors is nondangerous and safe since the edge does not come outside the other blade shoulder. Thus, since the scissors can be always used in a sharp state, the cutting quality of an object to be cut can be improved.

Abstract: PURPOSE:To make dialing/call reception during high-speed movement by forming a radio zone of a service area to be multi-layers. CONSTITUTION:When a call signal addressed to a mobile radio equipment 100 enters a radio control station 20 from a telephone network 10, the station 20 retrieves a storage circuit to check a current position of the station 100. The radio equipment 100 is moved at a high speed and whether or not the equipment 100 is in a broad position registration area is discriminated, the station 20 retrieves all radio base stations 30 according to the result and requests the transmission of an incoming call signal to the radio equipment 100 to a station group 30. The station group 30 sends an incoming call signal to the radio equipment 100. Upon the receipt of the incoming call signal from the station 30, the radio equipment 100 sends a reply signal to the station 30, the station 30 requests a command signal of radio channel selection to the radio equipment 100 and setting of a channel to the station 20, and the radio equipment 100 is in standby in a designated channel. As a result, a channel is set via the station 30 between the station 20 and the radio equipment 100. When a speech is finished, the radio equipment 100 sends a termination signal to the station 30 and the signal is transferred to the station 20 and the channel is released. Thus, the call reception during high speed movement is surely executed.

Filed: 1981-06-17
Abstract: PURPOSE:To realize the stable electric characteristics and optical characteristics through the life of the captioned lamp, by enabling sodium amalgam to exist steadily at the coldest point of a luminous tube. CONSTITUTION:3-15mg of sodium amalgam is charged and sealed into a luminous tube which holds its inside volume of less than 2cm<3> in which an electrode conductor having an electrode on its tip part is sealed to touch the inner surface of the end part. When the total amount of sodium amalgam 8 filled in the luminous tube 1 is less than 15mg, the variation of lamp voltage is small. Thereupon, when the total amount of sodium amalgam 8 is 1-2mg, the stable electric characteristics and optical characteristics can be maintained for a short period of time after manufacturing the luminous tube, (lamp aging 500-1,000hr) but thereafter, when lighting is carried on, the lamp-voltage begins to rise due to disappearance of sodium from the luminous tube 1.

Abstract: PURPOSE:To prevent the yield of hillockes, by providing slits in the direction of the flow of current in a lower metal wiring at a region, where an upper metal wiring crosses the lower metal wiring. CONSTITUTION:A first-layer Al wiring 2 and a second-layer Al wiring 3 are formed on a substrate 1 and isolated by an interlayer insulating film 3. A plurality of slits 4 are provided at the crossing part of the wiring 2 with the wiring 3. The part comprises the assembly of a plurality of thin wires each having a width of 1-2mum or less. The slits 4 are simultaneously formed in the patterning process of the wiring 2. In this constitution, the yield of hillockes in the heating process is prevented at the part, where the slits 4 are provided in the wiring 2. This is because the stress dispersion of the polycrystal of Al is effectively carried out in the heating process. Dielectric strength between the wiring 2 and the wiring 3 is sufficiently high and reliability is improved.
