Patent JP-S62171525-A (JP)
Title: Manufacture of universal coupling
Inventor: SHIMAZAKI NOBUO
IPC: F16D3/202
Filed: 1986-01-23
Abstract: PURPOSE:To improve durability and to reduce a universal coupling in size and weight by applying surface hardening to a shaft engaged with a needle roller bearing at least among members contacting the needle roller bearing, and then finishing same by cutting work to be subjected to low-temperature sulfurizing treatment. CONSTITUTION:After standard cementation quench-and-temper is applied to JIS case hardened steel tripod shaft 2 contacting a needle roller bearing 3, the shaft is finished by cutting work by the use of CBN (boron nitride sintered body) tool. The machining allowance of CBN tool is about 0.2mm, and low- temperature sulfurizing is performed by adding sodium sulfide to an alkaline metallic salt path. Thus, surface compression residual stress and a surface hardening layer are given by cutting work, so that an iron sulfide coat formed by low-temperature sulfurizing conducts a buffering action for abnormal contact. Accordingly, fatigue strength can be improved to increase durability, improve reliability,reduce in size and weight, and reduce the coupling to a compact size.

Title: Base frame for beryllium window frame or the like
Inventor: SUZAWA CHIZURU
IPC: G02B1/02
Filed: 1988-01-22
Abstract: PURPOSE:To suppress the damage and early thermal deterioration of a joint part, etc., by thermal strain and to maintain vacuum sealing performance with high reliability by providing a thin film layer of an inorg. material having a good heat transfer characteristic (for example, a thin film layer of diamond) on the surface of the title frame. CONSTITUTION:A base frame body 5 of a beryllium window 1 and a beryllium plate 2 are hermetically joined via a joining material 3. A coating layer 10 of the thin film of the inorg. material having the good heat transfer characteristic (for example, the thin film of diamond) is then provided on the surface of the body 5 and the surface of the joining material 3 except a groove 8 for mounting a metallic O-ring for vacuum sealing. This coating layer 10 is formed by, for example, a CVD method, etc., after the unnecessary points thereof are masked. The cooling property of the base frame and the material to be supported are greatly enhanced by such constitution, by which the remaining of the heat in the inside is substantially prevented and the damage, etc., of the joined part are suppressed. The vacuum sealing is thus maintained with the high reliability.

Title: Switching power source circuit
Inventor: IMAMURA MASAHIRO
IPC: H02M3/28
Filed: 1991-02-04
Abstract: PURPOSE:To eliminate a phase correction of an error amplifier by emitter- grounding an output transistor of a photocoupler to be used for feeding back. CONSTITUTION:A signal amplified by an error amplifier 14 is input to a light emitting element 5a of a photocoupler, and transmitted to a primary side. Since a phototransistor 5b is emitter-grounded, when an output voltage of a power source circuit is raised, a collector output voltage is lowered, and a band is increased. This signal is so inverted by an inverting amplifier 7 that an output voltage is raised if the output voltage of the power source circuit is raised. A comparator 9 compares the signal with a reference triangular wave 8 as a feedback voltage, outputs a switching control signal if the wave 8 is larger to turn ON a switching transistor 3. An ON time is varied according to the amplitude of the feedback voltage. Accordingly, the output voltage of the switching power source can be kept constant.

Title: Method for measuring strain of optical transmission path
Inventor: KAJIOKA HIROSHI
IPC: G01L1/24
Filed: 1985-01-29
Abstract: PURPOSE:To measure strain in parallel with information transmission by superposing a signal for strain measurement on a signal for information transmission, making incident the superposed signal on an optical fiber and measuring the strain of the optical fiber from the phase change of the signal for strain measurement separated from the emitted signal. CONSTITUTION:The pulse signal for information transmission and the sinusoidal wave signal for strain measurement from an oscillator 1 are superposed in a superposing circuit 8 and the superposed signal is converted to a light signal by converter 2 and is made incident on the optical fiber 3. The light signal is converted 4 to an electric signal on the exit side and the information signal is transmitted through a high-pass filter 9. The signal for strain measurement is separated by a low-pass filter 10 and is inputted to a phase meter 6 which detects the phase difference between said signal and the signal from a reference signal generator 11 synchronized with the oscillator 1. The strain generated in the optical fiber cable 7 is determined from the change thereof. The online strain measurement with good accuracy is thus made possible simultaneously with the information transmission without affecting the signal for information transmission.

When the image data are printed out, the file number and an originator which are extracted from the table 52 are shown at a display part 2 with depressing of a selection copy key of an operating part 3. Then the file number is designated by a scroll key of the part 3. Based on the designation of the file number, the start address number of the memory 9 is read out of the table 52 and the image data are read out based on the start address number. Then the image data are printed out at a recording part 5.  Thus, the image data are freely extracted and then erased.

Abstract: PURPOSE:To form a shaking machine which can adjust the shaking amplitude of by turning positively and easily by a device wherein vibrating plate to which a shaking base is attached is mounted to a plurality of rotary wheels disposed around a driving wheel which can be moved and fixed at will. CONSTITUTION:Sliding grooves 5 with a plurality of concave grooves 5b for adjustment are installed at the same diameter line locations to a plurality of rotary wheels 4 (for example, three wheels) revolved at uniform velocity in the same direction by means of a drive wheel 3.

Title: Method and device for hooking jig for surface treatment
Inventor: SATOU SATORU
IPC: C25D17/08
Filed: 1981-02-03
Abstract: PURPOSE:To improve productivity by attaching and detaching a plating jig from a vertical direction by means of an automatic clamping system. CONSTITUTION:When arms 15 with pawls are put in the state of solid lines and a piston head 9 is lowered by operating a cylinder 7, a rack gear 10 which is one body with the head 9 descends as well. On the other hand, gear holders 13 supporting the arms 15 freely turnably are interposed with coil springs 11 and therefore they are descended as the head 9 descends. Since the gear 10 descends by passing through a bottom opening 18, an idle gear 16 operates and the gears 13 fixed to the arms 15 rotate in the direction opposite from that of the gear 16, thereby bringing the arms 15 to the position (a) from the position (b) extending to the extreme length from a casing 5, and compressing the springs 11. Hence, if the casting 5 is conveyed to each treating cell and the head 9 is displaced by the stroke S, the plating jig is hooked or released.

Abstract: PURPOSE:To upgrade energy resolution to radioactive rays irrespective of their incident direction and largeness, by juxtaposing plural sheets of thin units, which have electrodes formed on their facing surfaces, or by forming grooves on a large crystal plate to have a plurality of divided units. CONSTITUTION:Radioactive-ray detection units N1 to N5, which are individual elements having electrodes 2 formed on both surfaces of a crystal plate 1 made of CdTe, are laminated through insulating materials 4 so as to represent a radioactive-ray detection element. In order that carriers, which are generated in the crystal by incidence of the radioactive rays (shown in arrows), that is, electrons and holes are made to advance completely to the electrodes on both sides of the crystal and collected, a thickness of the element in each unit is made smaller than a movable distance of one carrier which can move depending on quality of the crystal for use at a smaller distance than the other carrier. Collective efficiency of carriers becomes higher as a result by thus thinning the element in each radioactive-ray detection unit.
