Title: Cap device for recording medium insertion port
Inventor: SUGANO TAIJI
IPC: G11B33/02
Filed: 1994-10-31
Abstract: PURPOSE: To prevent entering of dust, etc., with a simple structure by holding a cap on a recording medium insertion port except the time when a recording medium is inserted/ejected between a pair of arm parts provided on the turning shaft of the cap by pressing force of an elastic member at a stopper position to close the cap. CONSTITUTION: The arm parts 13, 14 of both ends of the elastic member 10 having a connection part 12 of a coil spring hold therebetween the cap 9 turnable around the turning shaft 11 on the insertion port of a disk cartridge-(DC) 16 together with a stopper part 15. Then, though the cap 9 closes the insertion port by pressing force of the member 10 always, when the DC 16 is inserted into a main body in the direction of A, the cap 9 is pressed by the DC 16, and turned in the direction of A. At this time, though the arm part 13 is engaged with the stopper part 15, the arm part 14 is turned together with the cap 9 and wound up, and when the DC 16 passes through the insertion port, the cap 9 is returned to a usual state by the pressing force of the connection part 12.  When the DC 16 is ejected, the cap 9 operates in the direction opposite to the A direction, and the arm parts 13, 14 operate similarly reversely. Thus, the entering of the dust, etc., is prevented surely by the cap 9 always with the simple structure.

IPC: H01L23/31
Filed: 1985-11-29
Abstract: PURPOSE:To prevent generation of a gap between a lead and a resin package by a method wherein the width of the upper resin molding part of the resin package is made smaller than the width of the lower molding part. CONSTITUTION:The width W2 of the upper resin molding part 5 is formed smaller by 100mum or thereabout than the width W1 of the lower resin molding part 6. When a lead 2 is bent downward at the supporting point 2a, as both side edges of the upper resin molding part 6 are not present at the above- mentioned position even when the thickness of the lead 2 is reduced by stretching the outside of the lead 2 and also the external force working to push downward is applied to the lead 2, no exfoliation is generated between the lead 2 and the upper resin molding part 6, and no gas b1 is generated. Also, when metal molds are set, both side edges of the upper resin molding part 6 do not protrude over the lead 2 even when a positional deviation is generated on both left and right sides, because the positional deviation is normally 40mum or thereabout. Accordingly, the gap b2 is not generated.

Title: Traverse grinding attachment
Inventor: IWATA ISAMU
IPC: B24B5/04
Filed: 1984-12-20
Abstract: PURPOSE:To prevent a feed mark from occurring, by varying a traverse speed in an interval between strokes of a traverse table periodically. CONSTITUTION:In a traverse table 1, a feed speed serving as a criterion is set by a table speed regulating value 6. On the other hand, a feed speed varying valve 8 makes a spool reciprocate periodically, making it discharge hydraulic pressure intermittently out of a hydraulic pressure discharge route 7 so that the feed speed of the table 1 varies periodically, thus feed of the table 1 comes to an unequal rate. And, a traverse speed of the table 1 is varied periodically whereby stepped-form wear on a grinding wheel G comes into a successive state showing a gentle inclination blurring a step difference (b), thus an unremoved part in a work W is brought to nothing in consequence.
