Filed: 1981-03-06
Abstract: PURPOSE:To erase only the specific signal in the reproduction mode without affecting other signals, by forming the recording and reproducing parts with a phase shifter set at a prescribed constant, an adder, an amplifier etc. CONSTITUTION:For an adder consisting of a phase shifter set at a prescribed constant, etc., the acoustic signals A and B are supplied to phase shifters 1 and 4 with the signal C to be erased in the reproduction mode is supplied to the systems 2 and 5 respectively for example. Then the signals A(theta1) and B(theta2) obtained by giving a shift of phase to the signals A and B through the shifters 1 and 4 are transmitted to the adders 3 and 6. On the other hand, the signal C is branched and transmitted to the adders 3 and 6 via the systems 2 and 5. Thus two signals X and Y are delivered to a recorder and reproducer 7. The reproduction outputs X' and Y' are delivered by the recorder and reproducer 7 to be supplied to electric power amplifiers 12 and 13 through switches 11 and 11' in the stereophonic reproduction mode. In the erasion mode of the signal C, the outputs X' and Y' are processed through an amplifier 8 and an inverter 9. Then the signals having a 180 deg. phase difference from each other are supplied to an adder 10 to erase the signal.

Abstract: PURPOSE:To enable the detection of distortion at a high accuracy without increasing the length and diameter of a pin, by inserting a sleeve in the circumference of a pin to be made in a double axis so that only the center of inner circumference of the sleeve will be brought into contact with the circumference of the pin. CONSTITUTION:A pin 1 is supported with shaft holes 3 and 3' provided on side plates 2 and 2' arranged at an interval (b) with the diameter (d) while the pin 1 is cased with a sleeve 4 whose inner diameter at the axis-wise center is small while the inner diameter at both ends thereof large. The sleeve 4 is so arranged as to contact the circumference of the pin 1 only in the section CC' (with the distance of roughly b-2d) at the center and not in the sections AC and A'C' [with the distance of (d)] at both ends. At this point, the force W working on the entire area between the side plates 2 and 2' acts on the pin 1 concentrating on the section CC' at the center where the sleeve 4 contacts the pin 1 to create the sections AC and A'C' necessary for the detection of distortion at a high accuracy.

Title: Semiconductor device
Inventor: AKASHI TSUTOMU
IPC: H01L23/522
Filed: 1984-02-24
Abstract: PURPOSE:To increase stability on the formation of wirings, and to improve the yield of acceptables by expanding the wiring spaces of two opposite sides of the wiring space sections of lower layer wirings at positions crossing with an upper layer wiring disposed crossed at right angles through the lower layer wirings and an inter-layer insulator. CONSTITUTION:When two opposite sides of first layer wiring space sections are retreated and a wiring space is expanded in crossed sections with a second layer wiring 13 of first layer wirings 10 running parallel, the degree of coating of the second layer wiring in the wiring space sections is improved largely because the wiring space is extended in the recessed sections 11, 12 of the first layer wirings. The second layer wiring 13 runs on the first layer wirings 10 running parallel through an inter-layer insulator 15. Since the first layer wiring spaces in the crossed sections of the first and second wirings are extended, a shallowing effect on the coating of the inter-layer insulator and an upper layer wiring metal is eliminated, and the second layer wiring having the excellent degree of coating at the stepped sections of the first layer wirings is obtained. The recessed sections of the first layer wirings at the crossed sections of the first and second layers may be formed to two opposite sides, or may be formed to one side.

Title: Time-piece
Inventor: ITO HAJIME
IPC: G04R20/00
Filed: 1990-02-16
Abstract: PURPOSE:To correct time using the time signal given by radio broadcasting by performing the 0-min correction of time when predetermined time signal is simultaneously detected from at least two receivers capable of receiving different channel broadcastings. CONSTITUTION:When one receiver 1 receives a first AM broadcasting and the other receiver 2 receives a second AM broadcasting, the respective outputs of the receivers are connected to time signal detection circuits 3, 4. When it is assumed that the detection circuits 3, 4 respectively generate the output of an H-level at the input time of time signal sound and the output of an L-level at the time of the input of other signal, since the L-outputs from the detection circuits 3, 4 are inputted to an AND gate 5 during the time of ordinary program, the outputs thereof become L and the time 0-min correction circuit 7 of a clock circuit 6 is not driven. When predetermined time signal sound is generated during this program, H-outputs are inputted to the AND gate 5 from both of the detection circuits 3, 4. Therefore, the output of the AND gate 5 becomes H and the time 0-min correction circuit 7 of the clock circuit 6 is driven by an H-signal to perform the 0-min correction of a time-piece.
