Abstract: PURPOSE:To prevent deterioration of pressure resistance due to generation of deviation in reference with a resin body without increasing a screw hole especially by forming the screw hole of a header as an oblong circle or an ellipse in a direction crossing a lead direction at right angle. CONSTITUTION:When a lead frame of a plurality of units is supported sideways by a common frame, a horizontally long circular screw hole 2 is provided at a central portion of each header 1 consisting of a cooling material metal plate. A central inner lead 3 out of a set of three leads is formed in one piece with the header 1 and the inner lead at both sides has a post within the inside and then is separated from the header. An outer lead 4 is extended to an extension of each inner lead, a tie bar 6 is formed across the lead at a boundary portion between the inner lead 3 and the outer lead 4. Since the screen hole can be formed in an oblong circle, a width of the resin can be secured.

Title: Rear suspension of automobile
Inventor: MAEBAYASHI JIROU
IPC: B60G3/26
Filed: 1982-06-26
Abstract: PURPOSE:To contrive to improve the running stability by a simple structure wherein the mounting location of a spring unit, which functions as a damper, is provided so that its spring reaction is applied to a wheel hub at the bumping so as to toe-in a wheel. CONSTITUTION:A spring unit 8 is mounted to the wheel hub 2 at the back of the virtual vertical rotation axis P of the wheel hub 2 in an path outwardly and downwardly inclined from a car body side. Consequently, when the wheel 1 bumps, a semi-trailing arm 3 pivots about bushings 4 connected to a car body, resulting in oscillating the hub 2 connected to the arm 3 at its rear end together with the pivoting motion of the arm 3. In this case, an outward and downward spring reaction force is generated in a spring unit 8 as the reaction force of bumping load in order to apply at the back of the virtual rotation axis P. Accordingly, the hub 2 is rotatingly displaced about the axis P toward the direction to toe-in by means of the outwardly horizontal component of spring reaction force, resulting in changing the wheel to toe-in and consequently improving the running stability.

Title: Vortex prevention device for pump
Inventor: KATOU SUSUMU
IPC: F04D29/66
Filed: 1977-09-13
Abstract: PURPOSE: To minimize the waste of electric power and the reduction of water sucking efficiency by operating a vortex prevention device only when irregular vibration is detected, taking advantage of the fact tht such irregular vibration takes place when a pump sucks in vortexes.  
     CONSTITUTION: When the operational condition of a pump 12 worsens to cause vortexes during the water suction with the pump 12, and the irregular vibration by cavitation is generated due to the suction of vortexes through the pump suction port 11, a vibration detecting device 4 near the pump 12 detects the disorder and sends the signal to the control section 6. This control section 6 opens a controling valve 51, usually closed, and part of water sucked through the pump suction port 11 is then sent into the separate pipe 5 to inject as injection water 8 through an injection nozzle 2 against the suction port, thereby breaking the turbulent flow and preventing the generation of vortexes. When the vibration of the pump 12 stops, the controling valve 51 closes in response to the detection at the vibration detection device and the injection of pressurized water 8 stops

Abstract: PURPOSE:To mass-produce the title ultra-fine powder by providing an anode and a cathode in a reaction vessel, impressing a high pulse voltage to generate streamer discharge in a raw gas, and causing a chemical reaction due to an electron avalanche to form ultra-fine powder. CONSTITUTION:When a pulse voltage 19 is impressed on the cathode 14, the electron 20 emitted from the cathode 14 collides with a seed electron takeout window 6, and seed electrons 21 are flown out from the seed electron takeout window 6, suspended, and diffused. When the electrons are almost sufficiently diffused in a discharge space 11, a delayed pulse voltage 22 is impressed between the cathode 3 and the anode 2 for a short time. In this case, the number of electrons is increased on a chain reaction basis with the seed electron 21 as the initial point. The electron avalanche is uniformly generated in the space, and grown into a stabilized pulse streamer discharge which continues for a short time. The molecules of the raw gas flowing in the discharge space 11 are collided with the electrons, and ionized. As a result, radical atoms are generated, the reaction of an active species and formation of crystallites are carried out, and ultra-fine particles are formed.

Abstract: PURPOSE:To sharply improve the measuring accuracy of the magnetizing characteristics of a steel plate by directly connecting pressurized air jetting means to the input side and output side terminal parts of a york and allowing the traveling steel plate to approach the york itself in noncontact state. CONSTITUTION:Eight air compressors 32 are driven and compressed air with a previously set prescribed pressure is led into respective chumbers 26 in chumber members 20 respectively arranged on the inlet side end part 12A and the outlet side end part 12B.

Title: Scroll type compressor
Inventor: TERAUCHI KIYOSHI
IPC: F04C18/02
Filed: 1981-07-16
Abstract: PURPOSE:To restrain the leakage of fluid caused by the difference of the change of thermal expansion by changing the thickness of the wall of a scroll body between its central and circumferential part to construct the wall thickness of the circumferential part a little thinner for ensuring the linear contact between scroll bodies in a pocket part of high-pressure fluid. CONSTITUTION:Walls of two scroll bodies near their central parts are constructed a little thicker than in other parts for obtaining perfect linear contact. In this construction, even if a small error is given in the wall processing in other part, it cannot influence the seal at the central part, and even for the leakage of the non-contact part in the circumferential part, the small difference of pressure allows to restrain the influence to the volumetric efficiency at a low level. meanwhile, even when the temperature is risen during the operation of a compressor, since perfect linear contact can be obtained in the parts almost equal in the thermal rising rate, the generation of a gap caused by the difference of the change of thermal expansion at a high-pressure part can be prevented for also restraining the leakage of fluid.

Abstract: PURPOSE: To increase the reliability as well as realize a low cost for the DC stabilizing power supply unit, by supplying the reference voltate to be applied to the error amplifying circuit and the protective circuit from the same voltage source.  
     CONSTITUTION: The error amplifying circuit A1, the overvoltage detecting circuit C1 and the low voltage detecting circuit C2 are incorporated into the same integrated circuit. And at the same time, each reference voltage is supplied from the stabilizing power source VC via the bleeder resistances R 1 WR 6 . In such constitution, the detecting circuit works with the voltage set through the resistances R 1 W R 6  to the output voltage at the normal time although the output voltage VOUT may become abnormal. Accordingly, the detection voltage of the protective circuit has not be controlled newly if the R 1 WR 6  are set in a proper relation. And the relative ratio of each reference voltage is decided only by the relative ratio of the R 1 WR 6 , and thus a sufficiently high-accuracy setting is possible with the resistance within the element of the integrated circuit. In such way, not only the enhancement of reliability but a low cost can be realized for the power supply unit.
