Title: Brazing plate type heat exchanger
Inventor: HORIGUCHI AKIRA
IPC: F28F3/08
Filed: 1998-03-31
Abstract: PROBLEM TO BE SOLVED: To eliminate affection to the performance of a heat exchanger, which is accompanied by the smaller moving amount of heat of a first fluid passage, having a second fluid passage at only one side, compared with that of the first fluid passage, having the second fluid passages at both sides of the same. SOLUTION: In a brazing plate type heat exchanger, constituted of a plurality of superposed heat transfer plates 1 connected permanently by a brazing material, the amount of brazing filler material 7 at the fluid inlet port of a first fluid passage R, having a second fluid passage W at only one side of the same, is more increased compared with that of a first fluid passage R, having the second fluid passages W at both sides of the same, whereby the fluid inlet port passage is narrowed and the flow rate of fluid is limited. When a thin copper sheet is interposed as the brazing filler material 7 between the heat transfer plates 1 to connect then permanently by heating and brazing them in a furnace, for instance, a good result can be obtained by thickening the copper sheet at the fluid inlet port of adding an annular copper sheet.

Title: Device for automatic exposure to x-rays
Inventor: IKEDA MITSURU
IPC: H05G1/30
Filed: 1981-06-08
Abstract: PURPOSE:To execute optimal exposure to X-rays, by providing a multiple light intake section  at the side of the output of an image intensifier to detect the shortage and excess of the exposure to X-rays and by removing outputs based on the detected shortage and excess, to  determine an optimal light intake field of vision to maintain said field throughout the stoppage of seeing-through and throughout photographing. CONSTITUTION:An examined body 2 is exposed to X-rays from an X-ray tube 1. The shortage  and excess of the exposure are detected through a multiple light intake section 11 provided at  the side of the output of an image intensifier 4 and are latched at 23. For seeing-through, a  changeover unit 31 is connected to a comparator 32 to automatically adjust the seeing-through  conditions and another changeover unit 36 is put in its positon of X-ray exposure. When a seeing-through switch 38 is turned on, a gate 34 is opened to apply the output of a changeover  signal generator 33 to a selector 12 to remove light intake fields of vision based on the channels of the shortage and excess. A switch 37 is then turned on through a delay circuit 35 to  perform the seeing-through. When the seeing-through switch 38 is turned off, the gate 34 is  closed to maintain the last conditions of the seeing-through and the irradiation of the X-rays is stopped through the delay circuit 35. After that, the changeover units 31, 36 are shifted to  their positions of photographing and the switches 37, 39 are turned on, so that optimal exposure is effected through a phototimer 6.

IPC: H04M1/00
Filed: 1986-04-16
Abstract: PURPOSE:To attain the message recording/reproduction with small size and less power consumption by providing a register means interleaving a transmission/reception sound signal converted into a digital signal and a semiconductor voice memory means storing the interleaved sound signal. CONSTITUTION:A processing section 10 commands the changeover of a recording circuit switch 28 by the sound recording setting from a keyboard 12 and the output of a coder/decoder (CODEC) 4 is inputted to a shift register 15. The CODEC 4 applies A/D conversion while the sound signal is split into each frame at a prescribed sampling period, and a transmission/reception signal is intermittently interleaved at a prescribed interleaving interval based on the frame, the result is sent in the register 15 and the compressed signal is stored in a voice memory 18. The data in the memory 18 in the reproduction setting is stored once in the register 15, the CODEC 4 assigns again the data and converts it into an analog reproducing signal as to the data interleaved at the recording. Thus, the message recording/reproduction is attained with small size and power saving.

Title: Automatic cargo handling device
IPC: B25J5/00
Filed: 1992-03-13
Abstract: PURPOSE:To provide an automatic cargo handling device to prevent article contact at the time of bending displacement of the working arm of an industrial robot. CONSTITUTION:At the time when a working arm 4 of an industrial robot 2 to work to handle cargoes against a pallet 6 deviates from the surface of the pallet 6 and handles the cargoes, position of the industrial robot 2 is changed. Additionally, when the working arm 4 of the industrial robot 2 makes contact with an article 7, the working arm 4 is bent in the outer peripheral direction of the pallet 6 surface. Consequently, the working arm 4 moves in the direction where the article 7 approached at the time of cargo handling motion does not exist. Accordingly, it is possible to prevent loose breakage and fall of the articled due to contact of the bent working arm 4. Additionally, use efficiency of a cargo handling place is improved by reducing intervals between the pallets from each other.

Filed: 1983-05-21
Abstract: PURPOSE:To ensure clearance, serving as a neumatic bearing, through prevention of hand drum-shaped deformation of a rotary sleeve and to ensure smooth rotary performance of the rotary sleeve through improvement of resistance to wear of the rotary sleeve, by a method wherein a composite layer, which has lower rate of thermal expansion than that of the parent material of the rotary sleeve, is formed on the outer peripheral surface of the rotary sleeve. CONSTITUTION:A rotary sleeve 17 is rotatably and floatably supported in a center housing 1 through the medium of a pneumatic bearing chamber 18, and a rotor 2, having vanes 16 insertably engaging therewith, is mounted inwardly of the rotary sleeve 17. A composite material layer 36, which has lower rate of thermal expansion than that of the parent material of the rotary sleeve 17, is formed on the outer peripheral surface of the rotary sleeve 17. This causes the composite material layer 36 to prevent thermal expansion of the parent material of the rotary sleeve through the entire surface of an outer periphery, and prevents thermal deformation of the entire rotary sleelve 17 and both end parts. The composite material layer 36 is formed by a fiber-reinforced metal, and this reinforces resistance to wear of the outer peripheral surface of the rotary sleeve 17 and prevents hand drum-shaped deformation of the rotary sleeve.
