Filed: 1986-07-09
Abstract: PURPOSE:To simplify the structure, by integrally forming a holder member for supporting a cam shaft and rocker shafts with a cylindrical portion having a spark plug insert hole extending obliquely, and commonly supporting rocker arms on the side where the cylindrical portion is provided, between adjacent two cylinders. CONSTITUTION:In an engine having intake and exhaust valves adapted to be opened and closed through and exhaust rocker arms 17 and 18 by the rotation of a cam shaft 14, the cam shaft 14 is rotatably supported to cam holders 31 fixed to an upper portion of a cylinder head 2 by bolts 29 and 30.

Title: Linear step motor
Inventor: SUGIURA MASATOSHI
IPC: H02K41/03
Filed: 1978-12-26
Abstract: PURPOSE: To directly cause an output shaft to perform straight step motion, by providing rotary magnetic poles which have a plurality of projections being fitted on a shaft screwed in a casing and by disposing stationary magnetic poles which have a number of projections and coils different in number from that of the projections of the rotary magnetic poles and are placed near the peripheral surfaces of the rotary magnetic poles.  
     CONSTITUTION: Rotary magnetic poles 3 secured on a shaft 2 have five projections 3a∼3e. Stationary magnetic poles 4 secured on the inside of a casing 1 extend toward the magnetic poles 3 and have four projections 4a∼4d in positions to equally divide the circumference by four. The adjacent coils 5a∼5d on the magnetic poles 4 are wound in the opposite direction to each other. When the projections 3a, 4a face each other and the coils 5a, 5b are energized, the magnetic poles 3 are rotated counterclockwise by 9° and stopped in such a position that the maximum magnetic energy is produced. If the shaft 2 has right-hand screw threads, it is stepped rightward. When the current of the coil 5a is cut off and other coils 5b, 5c are energized, the magnetic poles 3 are rotated counterclockwise by 18° and the shaft 2 is stepped by a corresponding quantity. The shaft can thus be directly stepped.

Title: High-temperature characteristic measuring device
Inventor: FUJISHITA TOSHIHIRO
IPC: G01R31/26
Filed: 1990-06-20
Abstract: PURPOSE:To enable high-temperature characteristic measurement to be made easily without producing electrostatic damage of an IC due to air friction by restricting temperature reduction of the IC at a measurement part by forming a warmed-up high-temperature region including the IC rather than heated air. CONSTITUTION:An IC 1 is carried through a path 13a with a suction holding hand 2, is set to a socket 5, and is pressed from an upper part with a pusher 8 for performing test. On the other hand, a block 3a which incorporates a heater which is placed on a base 4 is heated, thus enabling the ambient air to be warmed up. The warmed-up air ascends and forms a high-temperature region 14. Then, in the IC 1, since this warmed-up high-temperature region 14 exists, temperature reduction is restricted and then temperature becomes stable since the IC is pressed by the pusher 8 which is incorporated in the heater. Therefore, no electrostatic electricity is produced since there is no friction with discharge air. If conditions for high-temperature test are set to for example 100 deg.C, temperature reduction of the IC 1 can be restricted if temperature of the high- temperature region 14 is heated to approximately 70 deg.C.
