Title: One-way clutch
Inventor: TSUKADA MIKIO
IPC: F02N15/02
Filed: 1983-12-05
Abstract: PURPOSE:To prevent the nonuniform wear and eizure of the rollers of a one- way clutch, by inserting a retainer for holding a rotary bearing, in between the inside circumferential surface of the outer member of the clutch and the outside circumferential surface of its inner member, and using a clutch over to secure the retainer. CONSTITUTION:The inner member 3 of a one-way clutch functions as a spline tube and is placed on a helical spline member 4. Rollers 2 and springs for pushing the rollers are provided between the outside circumferential surface of the inner member 3 of the clutch and wedge chambers 1a defined on the inside circumferential surface of the outer member 1 of the clutch. The rollers 2 are held through the action of a retainer 7 by lock-seaming the inner circumferential edge of a clutch cover 9. After an engine is started, the rollers 2 are pushed into the spacious wedge rooms 1a so that the inner member 3 of the clutch races. The outer member 1 of the clutch is then centered by needle rollers 6 held by the retainer 7. As a result, rollers 2 are protected from nonuniform wear and seizure.

IPC: F04D19/04
Filed: 1993-09-17
Abstract: PURPOSE:To reduce the number of part items for the purpose of compactness, facilitate manufacturing and dimensional management and provide a turbo vacuum pump having small performance fluctuation by forming cooling passages over the whole circumferences of a pump stator and a motor casing, respectively. CONSTITUTION:When a pump unit is driven by a motor unit comprising a coil 7a and a stator 7b, air which is sucked from an intake port 5 is compressed through a groove pump stage constituted of a rotor 1 and an intake casing 4 and a vortex pump stage constituted of the rotor 1 and the stator 2, and then, is exhausted through an exhaust port 8. In the vortex pump stage, the air flows through the intake port 12 and is exhausted toward the radial direction by a vortex blade 9 which rotates at a high speed, to flow inside a ventilation path 10 in a spiral manner, and then, is exhausted through the exhaust port 13. Consequently, the rotor 1 and the stator 2 are formed integrally with each other, thus achieving cost reduction. Moreover, if the rotor 1 and the stator 2 are inserted or drawn in the axial direction for assembling or disassembling, an assembling time can be shortened and assembling precision can be enhanced.

Title: Level plate for surface grinder and its manufacture
Inventor: IKEMOTO KIYOSHI
IPC: B24B37/12
Filed: 1992-08-06
Abstract: PURPOSE:To provide a level plate for a horizontal grinder which makes pellets hardly come off, and well holds abrasive solution. CONSTITUTION:A plural number of grinding pellets 3 composed of diamond abrasive grains are attached to the surface of a metallic level plate main body 2 in a doughnut shape in a desired arrangement pattern while being spaced as one wishes, and concurrently synthetic resin 4 is filled in each gap between the respective pellets, so that the level plate 1 is thereby formed. By this constitution, since the circumference of each pellet 3 is sealed so as to be hardened with synthetic resin 4, each pellet hardly comes off. Since grooves from which abrasive solution flows out, are blocked with each gap between the respective pellets 3 filled in with synthetic resin 4, abrasive solution is well held therein.

Title: Oscillation circuit
Inventor: SAWAMURA AKIRA
IPC: H03B5/32
Filed: 1988-09-16
Abstract: PURPOSE:To prevent the making of a circuit into an IC from being disturbed by a phase setting circuit by providing a transistor in which a resistor when being energized changes, corresponding to a voltage value applied on the phase setting circuit is set as a phase deciding element. CONSTITUTION:The title circuit is constituted in such a way that the transistor consisting of an N-channel MOS transistor is connected between the one end of a capacitor 8 and reference potential (ground) as a capacitor means in the phase setting circuit and a DC voltage V is applied on the gate of the transistor 9. The transistor 9 is energized by applying the DC voltage V, and also, since the resistance value of the transistor when being energized changes corresponding to the value of the DC voltage, an oscillation frequency can be controlled by controlling a phase by the DC voltage V. In such a way, since no capacitor for DC cut is required in the phase setting circuit, the occupant area of the phase setting circuit can be reduced, which results in the easy miniaturization of an IC chip.

Filed: 1983-12-08
Abstract: PURPOSE:To decrease the number of component parts and assembling processes by fixing by adhesion a main shaft to an inside ring of a ball bearing and therefore omitting a spacer for gap control between rotary transformers. CONSTITUTION:A main shaft 4 is put through a pair of ball bearings 6-a and 6-b which are pressed into a lower fixed drum 2, and the shaft 4 is fixed to the inner ring of the upper ball bearing 6-a with an adhesive 16. Then both ball bearings are pressureized by means of a pressurizing spring 8 and a pressurizing boss 9. At the same time, a rotary transformer 7-b of the fixed side is fixed into the drum 2 with an adhesive, etc. Then a rotary disk 5 attached with a rotary transformer 7-a of the rotary side is fixed to the shaft 4 with adhesion from above. In this case, a spacer 17 having the thickness equal to the length of a set gap is put between both transformers which are opposite to each other. Thus the length of the gap between both transformers is decided. Then the spacer 17 is pulled out. In such a way, the selecting process can be omitted for the spacer 17. This decreases greatly the number of assembling processes and improves greatly the mass production effect.

Title: Semiconductor integrated circuit device
Inventor: SATAKE TOMOMITSU
IPC: H01L21/60
Filed: 1983-12-09
Abstract: PURPOSE:To cut down the production cost preventing any defective edge touch from happening while improving the production yield and quality level by a method wherein an additional bump if formed on the surface of a bump independent of an internal element connecting to the first bump exceeding the height of a bump electrode. CONSTITUTION:An additional bump 7' is formed on a bump 7 independent of an internal element to make the total height 9 almost twice as much of the height of a bump electrode 2. After forming a bump electrode 2 and a bump 7, the additional bump 7' may be formed utilizing photoresist processing technology so that a semiconductor wafer may be coated with a resist film leaving the part where the pump 7' is to be located and the pump 7' may be formed of a metal up to specified height on the surface of the bump 7. When the bump electrode 2 is connected to a lead frame 1, even if the relative position of a tool to the bump electrode 2 slips toward edge side of the semiconductor chip, any defective edge touch may be prevented from happening since the lead frame 1 of the semiconductor chip after connection does not fall down being blocked by the additional bump 7'.
