Abstract: PURPOSE:To make the thickness of the thin wall part of a resin enclosure uniform and proper by a method wherein an overhang having a step part or an oblique part is provided on an end of a semiconductor chip holder part to prevent the holder part from oscillating in case of pulling out an alignment pin. CONSTITUTION:An overhang 20 having a step part 20a is integratedly connected to the end on the inverse side to the lead 3 side of a semiconductor chip holder part 1; the step part 20a faces to the surface 1c side of the rear surface of the surface 1a; while the overhang 20 protrudes from the surface 1a in the thickness direction by the extent of the step part 20a. Next, when melted resin P is poured from a gate part 16a facing the step part 20a into a metallic cavity 18, the resin P is slowly fed to the gap G made between the surface 1c and the metallic mold 17 to be filled up with the resin P further advancing on the surface 1a side. Next, when the cavity 18 is filled up with the resin P, an alignment pin 19 is pulled out. consequently, the thickness of a thin wall part can be automatically set up at proper value using the led-in resin pressure.

Abstract: PURPOSE: To automatically position and stop the rear end faces of panels differing in length at the same position by a method wherein a movable stopper is protruded or retracted on a conveying surface in accordance with the length of the panel being conveyed.  
     CONSTITUTION: When a panel 1 having a length of L is conveyed in B-direction along the conveying surface 5, one end 6b of a stopper component member 6 is at first depressed to the position of the surface 5 by the weight of the panel 1 and, interlockingly, a stopper piece 7c of a stopper component member 7 is retracted below the surface 5. However, when the rear end 1a of the panel 1 comes over a sloped upper surface 6c of the member 6, the member 6 is rotated clockwise by the effect of a weight member 10, while the member 7 is rotated counterclockwise to cause the stopper piece 7c to protrude above the conveying surface 5, stopping the front end 1b of the panel 1 and positioning it. On the other hand, when a panel having a length of 3/4 of L, the stopper piece 7c is not protruded above the surface 5, so that the panel is conveyed to a fixed stopper S, where it is positioned and stopped.

Abstract: PURPOSE:To quantitatively control the shape degree of a magnetic bubble transfer path by providing a control pattern consisting of a pattern group which varies continuously in at least one of inclination, interval, and width to the space part of a magnetic bubble memory chip. CONSTITUTION:A control pattern MP consists of a pattern MP1 for shape control formed by uniting two rod-shaped patterns 20 with pattern width (w) while a gap (g) of a tilt angle theta is left and a pattern MP2 for scale control which is formed by arraying rectangular patterns 21 in a longitudinal direction at the side parts of the rod shaped patterns 20 at equal intervals. If the shape control pattern MP1 which varies in gap (g) continuously with the tilt angle thetais left as a pattern residue 22 after a magnetic bubble memory element is completed without being etched completely as shown the hatched part of the gap (g), the size of the area of the pattern residue 22 corresponds to how inferior the shape degree of the monitor pattern MP is. The peak part of the pattern residue 22 is read on the adjacent pattern MP2 for scale control and thus evaluated quantitatively.

Title: Alarm circuit
Inventor: HARAGUCHI KAZUNORI
IPC: G08B23/00
Filed: 1978-05-15
Abstract: PURPOSE: To improve an operational efficiency by resetting an alram circuit only by switching an interlocking selector switch.  
     CONSTITUTION: When contact 16 is closed by an alarm signal, contacts 10a and 10c are closed, and pilot lamp 17 is lit, and alarm bell 12 issues alarm tone. When selector switches 9, 13 and 15 are brought into contact with contacts 9c, 13c and 15c, alarm bell 12 stops alarm, however, relay coil 10b holds the preceding state to light only pilot lamp 17. When generation causes of the alarm signal are eliminated, self-holding is continued though contact 16 is opened. When contacts of selector switches 9, 13 and 15 are opened, the pilot lamp is extinguished. Next, selector switches are returned to original positions. As a result, an operatinal efficiency can be improved by resetting the alarm circuit only by switching selector switches.

Title: Optical information recording and reproducing device
Inventor: UMEDA TOSHIKAZU
IPC: G11B7/013
Filed: 1983-04-06
Abstract: PURPOSE:To attain the control by increasing a frequency to write information at an outer circumference more than that at an inner circumference in response to write position on a disc without rotating control of the disc so as to increase the recording density. CONSTITUTION:An acoustooptic modulator 2 turns on/off a laser beam based on an output of a modulator 13 and a pit is formed on the disc 7 accordingly thereto. The scanning position (radial direction) of the laser beam is detected by a beam scanning position detector 11 and a voltage becoming higher as beam reaches an outer circumference of the disc more outward is outputted as a beam scanning position signal VP. A clock generator 12 generates a clock having a frequency in response to this position signal VP. The modulator 13 frequency- modulates a data read out of a memory 10 in synchronizing with the clock and feeds it to the acoustooptic modulator 2. The bit length is made identical on the entire face of the disc by making the period of the clock at a position reaching the outer circumference faster than that at the inner circumference, thereby increasing the recording density.
