Title: Crawler traveler
Inventor: IWAMOTO TAROU
IPC: B62D55/116
Filed: 1983-07-15
Abstract: PURPOSE:To make a car body keepable in horizontality irrespective of unevenness on a road surface, by controlling crawler forms at both sides separately corresponding with variations in a width direction of the road surface. CONSTITUTION:A planetary wheel 3 is always situated on a locus of elliptic mtion focusing a rotation center between a main wheel 5 and an auxiliary wheel 6. With this, each of crawler belts 4 at both sides of a car body 7 will in no case produce slackness even if the position of the planetary wheel 3 varies by rotation of a turning arm 1, so that constant tension is thus maintained. In addition, if the turning arm 1 of one side of the crawler belts 4 is rotated in the reverse direction against the turning arm 1 at the side of the other side crawler belt 4, the car body 7 is able to keep its horizontality. With this constitution, it can follow ups and downs on a road surface in the direction orthogonalized with the forward direction of the car body 7.

Title: Method and device for punching sheet-like article
Inventor: YAMANAKA YUTAKA
IPC: B31B50/20
Filed: 1990-05-15
Abstract: PURPOSE:To prevent a projected sheet-like article punching part from becoming misalingned with a punching blade position by insetting projecting parts of a sheet-like article formed by swelling the projecting parts, in each area between punching blades installed on a movable table and transporting the sheet-like article to a pressure application table descending position by hooking the side of the projecting part using the punching blade. CONSTITUTION:A movable table 2 which can move on a horizontal surface across an area extending from an upstream side to a downstream side of a press device equipped with a pressure-application table 13, and a guide table 5 and a delivery table 6 for the upstream side and the downstream side are arranged in a vertically movable manner. Then punching blades 3, each having a soft pad 31 attached to the lateral surface are provided projecting in a lattice form, on the lower surface of the movable table 2 so that the punching blades correspond to the arrangement pitches of for example, containers 90 of the sheet-like article 9. The containers 90 of the sheet-like article 9 are deposited on the guide table 5 at a descending position with the bottom of the container 90 turned upward, and the container 90 becomes insetted in an area between the punching blades 3 of the movable table 2 at an upper dead point. The movable table 2 moves intermittently with the punching blade 2 hooking the container 90 through the pad 31. Then the pressure application table 13 descends, synchronized to the stop of the movable table 2 and hits the movable table 2 to punch the container 90. The pressure application table 13 ascends and returns to its home position by a spring 24. Thus the same action is repeated.

Title: Automatic level adjusting circuit
Inventor: KOMORI YUUJI
IPC: H03G3/30
Filed: 1984-06-21
Abstract: PURPOSE:To prevent excessive automatic level adjustment due to noise by blocking overcharge of a capacitor for setting a time constant even when the attack time is set faster. CONSTITUTION:Since the sound recording level is decreased because of an ALC is applied too deeply when a shock noise is inputted with faster attack time in case of a microphone input mode, it is required to slow down the attack time. The attack time of transistors (TR) Q4, Q5 is quickened by applying a +B power voltage to a collector of the TRs Q4, Q5 for level detection via a resistor R5 in the ALC circuit when the mode is switched to a radio set input mode, that is, when a moving terminal (a) of the 1st changeover switch 19 is thrown to a fixed terminal (b) or (c).

The reflected light relating to the laser beam via the levorotatory plate 5L is made incident on the dextrorotatory plate 5R and is further optically rotated by the prescribed angle in a left direction. This reflected light varies in a progressing direction from the laser beam and, therefore, its optical path is bent by as much as prescribed component by a Rochon prism 4 and is cast to a photodetector 7. This photodetector 7 receives the reflected light described above and detects focus error, tracking error, magneto-optical recording signals, etc.

Title: Servo writer
Inventor: OISHI ATSUSHI
IPC: G11B21/10
Filed: 1990-05-18
Abstract: PURPOSE:To prevent quality from being lowered due to the irregularity of a head position after positioning by monitoring whether or not a magnetic head is located at a targeted position when a servo pattern is written. CONSTITUTION:An aberration detection circuit 14 decides whether or not the head position of a magnetic head 4 is deviated from a targeted position range in a servo write period synchronizing with a window signal representing the servo write period from a pattern generation circuit 7, and sends decision information to a microcomputer 8. When the head position of the magnetic head 4 is deviated from the targeted position range, the positioning of the magnetic head 4 is performed to a position where the aberration of a servo pattern can be corrected by issuing a command to a stage controller 12, and the servo pattern is read again. Therefore, even when the irregularity of the head position occurs after the positioning, the quality can be prevented from lowering by detecting the irregularity and writing the servo pattern again.
