Title: Keyboard device
Inventor: TOTSUKA ZENZO
IPC: H01H1/06
Filed: 1998-04-30
Abstract: PROBLEM TO BE SOLVED: To provide a keyboard device having contact parts enabling a manufacturing process to be simplified with less contact failure. SOLUTION: In this keyboard device, contact patterns 32, 42 and insulating resin films 34, 44 are formed by printing on confronting surfaces of parallel disposed insulating sheets 31, 41, respectively. The contact patterns 32, 42 are each made up of two half rings 32a, 32b having an outer diameter larger than a pressing surface of a contact-depressing rubber 15 of a mechanism part 10 and a diametral part 32c connecting the half rings 32a, 32b, and the patterns are formed of lines having substantially the same width as the wiring pattern 33. When the insulating resin films 34, 44 are formed by irradiating ultraviolet rays to printed insulating resin, the insulating sheets 31, 41 are prevented from being deformed by the heated contact patterns 32, 42, and therefore a spacer for securing a gap is not needed and contact failure of contacts, etc., are eliminated.

Title: Screw fastener
Inventor: ADACHI MINORI
IPC: B25B23/10
Filed: 1997-05-12
Abstract: PROBLEM TO BE SOLVED: To prevent breakage of an engaged part by releasing engagement by varying fastening force in accordance with a relative position of a diametrical contraction giving body to a holding body and varying diametrical contraction quantity of the holding body in accordance with strength of the fastening force. SOLUTION: When a screw 30 is engaged, a first operation part 16 is pushed in the rear end direction, and when the first operation part 16 is revolved until a set screw comes to a communicating point of a first groove part and a second groove part, the set screw makes contact with a front end part of the first groove part by energizing force of a spring. An engaging body 11a sinks in a holding body 12 and a diametrical contraction giving body. When the second operation part is revolved in the lock direction, the diametrical contraction giving body retreats, pressurizes a piece 121b of the holding body and fastens a head part of the engaged screw 30. When the second operation part is revolved in the free direction, the piece 121b returns to its original diameter which is not contracted in diameter. At this time, it is possible to easily release engagement of the screw as the piece 121b does not pressurize the head part of the screw 30.

IPC: G11B20/14
Filed: 1982-07-13
Abstract: PURPOSE:To prevent a malfunction, by performing an automatic change of a reference level only when the signal detected out of a recording medium is not omitted. CONSTITUTION:A signal omission detecting circuit is provided to detect the omission of signals. When the output (j) of said detecting circuit reaches L level, two gates 30a and 30b constituting an inhibiting circuit 30 are turned off to discontinue the working of a reference level changeing circuit 3. In other words, the output (i) of a comparator 25 repeats switches between H and L levels if a signal (a) exists and is kept at L level in a period T when a signal is omitted. The output (i) of the comparator 25 is supplied to a triggerable one-shot circuit 26. Therefore the Q output of the circuit 26 is set at L level during a signal omission period. During this period the circuit 30 is driven, and the circuit 3 is inactive. In such a way, a malfunction can be prevented.
