Title: Monkey spanner
Inventor: FUKUHARA MASARU
IPC: B25B13/16
Filed: 1999-01-07
Abstract: PROBLEM TO BE SOLVED: To operate a monkey spanner while keeping the initial gripping state in the fastening by forming the V-shaped holding grooves in the axial direction of a bolt or a nut to be gripped, on the grip surfaces of a fixed jaw and a sliding jaw. SOLUTION: The relative surfaces of a bolt B and a nut are rotated while held by the grip surfaces 1a, 2a of a fixed jaw 1 and a sliding jaw 2. When the slippage is felt in the final fastening, the relative ridge lines of the bolt B are engaged with the holding grooves 3, 3' for horizontal operation or the holding grooves 4, 4' for vertical operation to be gripped and rotated. By gripping like this, a monkey spanner is fixed horizontally or vertically to a bolt head, so that it does not run out in the rotation, and further the sliding jaw 2 is not removed from the bolt B even though it is slightly opened by its back space, so that a hand can be prevented from being injured by coming-off of the gripping part. The holding grooves 4, 4' for vertical operation can be effectively used when a small bolt is fastened, or when a space for turning the monkey spanner is narrow.

Title: Synthesizer tuner
Inventor: HIDAKA HIDENORI
IPC: H04B1/10
Filed: 1989-02-16
Abstract: PURPOSE:To prevent leak-in a clock signal from a clock generator after muting has been released by stopping a muting operating signal and stopping the clock generator, when a clock signal of the clock generator reaches a set value. CONSTITUTION:When a timing clock from a clock generator 6 reaches a prescribed number, a set pulse is outputted from a clock counter 11, and a flip-flop 13 is reset. Since a muting output of the flip-flop 13 becomes an 'L' level, the clock generator 6 stops an oscillation. In such a way, the clock generator 6 executes the oscillation only while the muting output of the flip-flop 13 is in an 'L' level, and its muting output becomes an 'L' level, that is, becomes a stopped state after muting has been released. In such a way, leak-in of the timing clock after muting has been released can be prevented.

Title: Unit for preventing parts of vibration type parts feeder from locking
Inventor: SASAKI TAKAO
IPC: B65G27/04
Filed: 1985-02-26
Abstract: PURPOSE:To prevent the lock of parts by loosely engaging a movable piece in a vibration type parts passage. CONSTITUTION:A movable piece 52 is loosely engaged in a vibration type parts passage 13 having a narrowed passage. For example, a concave portion 51 having desired shape is formed on the passage surface of a transferred parts locked position, and the movable piece 52 is loosely engaged in the portion 51. The hights of the upper surface of a parts passage surface 21 and the movable piece 52 are equal with each other so as to smoothly transfer the parts. A suitable gap is formed between the concave portion 51 and the outside of the movable piece 52, so that the movable piece 52 freely moves in relation to the concave portion 51. When the passage 13 is vibrated, the movable piece 52 vibrates through front, rear, right and left gaps in the concave portion 51 by means of the vibration of the passage 13, and the vibration manner of the movable piece 52 is different from that of the passage 13. According to the vibration, the parts are scarcely locked, and the parts are released immediately even when they are locked. Consequently, for example, specific parts, which are not permitted to be tumbled, can be automatically supplied.
