Title: Self-closing type door and article storage using same
Inventor: TSURUOKA YASUJI
IPC: G07F9/10
Filed: 1999-08-04
Abstract: PROBLEM TO BE SOLVED: To obtain a self-closing door which can be brought into contact with an opening part with the largest maximum force when closed and can be opened and closed with a light force and an article storage which can securely and smoothly carry articles out and open and close the door by using the door. SOLUTION: When a belt conveyor 23 is driven, a projection 25 is pressed against the rear end part of an article M, so the article moves toward the opening part to press a small door 28 from inside. The pressed small door 28 begins to rotate upward on a spindle 27 above it. Then a spherical weight 31 in the arm 30 rolls toward the base part of the arm to decrease the distance between the spindle 27 and weight and the moment applied in the closing direction of the small door 28 becomes small. Consequently, the small door 28 can easily rotate upward by being pressed by the article M moved by the belt conveyor 23.

Abstract: PURPOSE: To obtain a reproducing apparatus which simplifies a rotation control circuit and which reduces a circuit scale by a method wherein a disk is turned by a CAV system so as to perform reproduction. CONSTITUTION: A disk 1 in which information has been recorded by a CLV system is turned and driven by a CAV system so as to read out data.

Title: Synchronizing signal generator for video printer
Inventor: KUDO MITSURU
IPC: H04N5/76
Filed: 1985-10-09
Abstract: PURPOSE:To obtain a reproduction monitor picture and a printed one, both of which are faithful to their original pictures without a dot shift in a horizontal direction by resetting the operation through an H period pulse generator independently installed at the time of reading data out of a memory. CONSTITUTION:When output information from an A/D converter circuit 5 is written in a memory part 6, the polarity of a mode switching signal from an input terminal 2 is inverted, and the 1st and 2nd signal SW circuits are switched from a side (a) to a side (b). Due to this switching, a jitter-free HD1 pulse which is generated from a signal 4fSC being a reference clock signal from the 1st SW circuit 10 is outputted, while a VD1 pulse is outputted from the 2nd SW circuit 25 in the same manner. The rise of the pulse after resetting is released always becomes constant from the rise of the HD1 pulse. Information in the memory part 6 is read out without jitters through a memory control part 18, and outputted to a D/A converter circuit 7. Thus picture information stored in the memory can be properly reproduced without the dot shift in the horizontal direction.

Abstract: PROBLEM TO BE SOLVED: To provide an inspection facilitation design method for a route delay fault, which can obtain a high fault detection rate without considerably increasing area overhead. SOLUTION: The unprocessed route delay fault which is given in an integrated circuit is selected (S11). An initial pattern is generated for the selected route delay fault (S12), and logic values which are set in respective scan flip flops are stored (S13). A transition pattern is generated for the selected route delay fault (S14). It is judged whether the scan flip flop where the logic value is contradicted between the initial pattern and the transition pattern exists or not (S15). A D latch is inserted into the output signal line of the scan flip flop whose logic value is contradicted (S16). The contradiction of the logic value is dissolved by the D latch and the inspection of the route delay fault becomes easy.
