Title: Metallic material transporting device
Inventor: OKETANI HISASHI
IPC: B65G47/92
Filed: 1993-12-15
Abstract: PURPOSE:To transport metallic material easily, securely, and efficiently by combining a work attaching/detaching mechanism provided with an electromagnet to attract a work made of metallic material and a shock cylinder to push off the work, with a work transporting mechanism provided with a lift and/or a carrier. CONSTITUTION:In order to transport a work W made of metallic material, first a work attaching/detaching mechanism A is lowered until it is rested gently on the upper surface of the work W so as to detect its arrival at the time when an interval between both upper and lower based 3 and 5 is shortened and a base interval sensor 6 is operated. Next an electromagnetic 1 is turned on to attract only the uppermost wok W, and the work attaching/detaching mechanism A is raised. Then, at the time when the attaction of the work W is detected by a work detecting sensor 2, the whole work attaching/detaching mechanism A is transported to the next process by a work transporting mechanism B. Namely the work attaching/detaching mechanism A is raised by a lift 8, and moved by a carrier 9 in the direction crossed at right angles with the lift 8. After that, the work W is pushed off by a shock cylinder 7.

Title: Photodetector
Inventor: OGAWA HARUKI
IPC: H01L31/10
Filed: 1999-11-05
Abstract: PROBLEM TO BE SOLVED: To solve the problem that the length of a diffusion transit time of minority carriers generated in an epitaxial growth semiconductor layer attendant on a reduction in the wavelength of laser rays deteriorates a photodetector in high-frequency characteristics, and a PN junction is markedly increased in area to deteriorate the detector in high frequency characteristics if an opposite conductivity-type surface diffusion layer is formed on the semiconductor layer so as to shorten the diffusion transit time of minority carriers. SOLUTION: A P+-type surface diffusion layer 12 is formed into a prescribed pattern that contains belt-like regions on an N-type semiconductor layer 2, by which the diffusion transit time of minority carriers can be shortened without markedly increasing a PN junction in area, and furthermore an N+-type surface diffusion layer 11 is arranged between the belt-like regions of the P+-type surface diffusion layer 12 so as to lessen a photodetector in cathode resistance.

Title: Method for pressing down and compressing material by high-temperature fluid
Inventor: MIZUNUMA SUSUMU
IPC: B30B11/00
Filed: 1986-12-29
Abstract: PURPOSE:To prevent contact of a punch with fluid and to eliminate the need for sealing by interposing a granular material layer between the punch and the fluid at the time of charging a compressing material into a container for pressing in which the punch slides and compressing said material by the fluid as a pressure medium. CONSTITUTION:The compressing material 3 and high temp. fluid 4 of required temps. are charged into the container for pressing having an open hole of a cylinder part in which the punch 2 for pressing slides in an upper part. For example, stainless steel powder which is packed into a capsule or stainless steel powder which is subjected to compression molding is used as the compressing material. The part 5 of the high-temp. fluid 4 is quickly cooled to a solid state right after charging of the granular material 6 to prevent rising of the high-temp. fluid 4 at the time of pressing. The direct contact of the punch with the high-temp. fluid 4 is, therefore, prevented at least in the initial period of pressing and a sliding part 1-4 does not require the sealing mechanism or is simple in construction.

When either one of the speed detected value or acceleration detected value of the cage 1 obtained by the operation is respective standard values g1, V1 or more, the arithmetic control unit 13 judges the presence of a mischievous oscillation. When this judgment is obtained, the arithmetic control unit 13 outputs an operation instruction to an alarm 15 to give an alarm sound, also notifies a control instructing device 14 of this, and receives an emergency stop instruction from the control instruction device 14 to urgently stop the cage 1 once in that place.

Abstract: PROBLEM TO BE SOLVED: To make curing time faster by using a photosetting adhesive and to shorten the time for assembling an optical fiber and a ferrule by composing the parts above or below fiber holes of a material which allows the transmission of curing light for the photosetting type adhesive. SOLUTION: The parts or circumferential parts above (or below) the fiber holes 14 of the main body 12 of the ferrule 10 are formed of the material, for example, a transparent material 20, having excellent transmittance to the curing light for the photosetting adhesive so that the light is made incident on the circumference of the fiber holes 14 through this transparent material 20. Epoxy resins, acrylic resins, silicon based materials, glass, etc., are usable for the transparent material 20. The term 'transparent' of this case signifies that the transmittance is excellent to the light for irradiation (curing type). Then, the term is not always limited to visually transparent. The light entering from above is consequently made to arrive at the fiber holes 14 without attenuation.

Filed: 1992-11-26
Abstract: PURPOSE:To attain reproduction of high quality by descrambling a multi- sampling encoding signal and validating an iteration flag in the outputted multiple sampling encoding signal until the completion of waveform equalization. CONSTITUTION:When a power supply for a high quality television(TV) pay broadcast decoder is turned on, a waveform equalizing device 30 stars the sampling of a VITS signal for multi-sampling encoding (MUSE).

An iteration flag changing device 90 validates an iteration flag in a transmission control signal. The device 30 determines a filter coefficient, and at the time of completing waveform equalization, a flag output from the device 30 indicates the completion of waveform equalization, so that the output of the device 150 is invalidated and the device 90 does not change the iteration flag.

Abstract: PROBLEM TO BE SOLVED: To prevent the supply of water low in the concn. of effective chlorine at the beginning of the start of water supply and to prevent the water pollution caused by the transpiration of effective chlorine and the penetration of bacteria. SOLUTION: Since a specified electrolytic energy is applied to a pair of opposed electrode plates at every specified interval time after the stop of water supply to perform auxiliary electrolysis, even when the concn. of effective chlorin in water stagnated in hermetically closed electrolytic cell lowers at a time of the stop of water supply, this state is restored by auxiliary electrolysis to certainly prevent the supply of water low in the concn. of effective chlorine at the beginning of the start of water supply. Further, since tap water F is electrolyzed on the way of water supply in the non-contact state with the open air within the hermetically closed electrolytic cell, formed effective chlorine can be effectively utilized to perform expected sterilization and the penetration of bacteria from the outside can be prevented to certainly avoid water pollution.
