IPC: G11B7/004
Filed: 1983-01-31
Abstract: PURPOSE:To perform recording with no deterioration in recording density by moving back an optical head for waiting by a prescribed distance when the recording or reproduction is discontinued, then starting the recording or reproduction again at the position where the recording or reproduction of a recording medium is discontinued after the optical head is moved forward again. CONSTITUTION:In case the record information is discontinued, a recording head 17 is moved back by a fixed distance and stopped there for waiting the next recording. Then the head 17 is moved forward again when the preparation is through with the next recording, and the information is recorded again at a point where the record information is discontinued. The head 17 is driven toward the radius direction of a disk (recording medium) 1 by a driving motor 18. This motor 18 is controlled by a motor control circuit 19. A controller 12 transmits a control signal 20 to the circuit 19 to indicate the advance, retreat and stop of the motor 18, while a signal 21 showing the head position is sent to the controller 12 from the circuit 19.

IPC: C22C9/00
Filed: 1983-01-29
Abstract: PURPOSE:To provide a titled copper alloy having excellent strength and heat resistance in combination with substantial conductivity and having good bendability, plating adhesion and solderability by consisting the same of specifically composed Fe, Cr, Sn and Cu. CONSTITUTION:A copper alloy contains 0.05-0.30wt% Fe, 0.03-0.30% Cr and 0.05-0.40% Sn and consists of the balance Cu and is suitable as a lead frame material for semiconductor apparatus. The copper alloy is formed by using Cu as an essential material, adding Fe, Cr and Sn thereto, solutionizing Sn to strengthen the base material and precipitating Fe and Cr as microprecipitate. The excellent strength, heat resistance, conductivity, plating adhesion, solderability, etc. are thus provided to said alloy and the coefft. of thermal expansion thereof exhibits the value roughly similar to the value of a conventional copper alloy. The reason for limiting the above-mentioned additive components lies in that, if the above-mentioned componets are added at the lower limits or below, desired strength and heat resistance are unobtainable and that, if they are added at the upper limits or above, the electrical and heat conductivity and other characteristics are deteriorated.

Title: Continuous punching device
Inventor: MOCHIZUKI MASANORI
IPC: B26F1/40
Filed: 1988-01-22
Abstract: PURPOSE:To constantly keep the surface of a base-sheet fed onto a punching section smooth to substantially increase the durable number of punchings of the base-sheet by locating a part of the return route of the base-sheet between a bed in the punching section and the base-sheet on the feed route side. CONSTITUTION:When a product A is punched, indentations are produced on the surface of a base-sheet 11 on the feed route side. When the base-sheet 11 continues to travel, the part where the indentations are formed is returned to the upper surface of a bed 10 with increasing the number of punchings. Under the condition where the part of the indentations is returned, and when the punching operation is completed, the surface of the base-sheet 11 having the indentations is abutted on the surface of the bed 10, and a pressurizing force produced at the time of punching out the product A from a base-sheet material acts on the base-sheet 11 on the lower side through the base-sheet on the feed route. And the indentations of rugged cross section formed on the base-sheet on the return route are pressurized against the surface of the bed 10 to be crushed. As a result, the surface of the base-sheet 11 fed onto the punching section can be constantly kept smooth.

Filed: 1980-02-08
Abstract: PURPOSE:To enable plural kinds of communications at the same time by using several wavelengths when received an optical signal of the same wavelength as that of a signal transmitted from a station by converting said signal into a optical signal of another unused wavelength and by outputting it. CONSTITUTION:When station S1 starts transmission to station S3 with wavelength lambda1 and station S2 also starts transmission to station S4 with wavelength lambda1 at the same time, the signal of wavelength lambda1 with the address of S3 arrives at S2 from S1 and is received by lambda1 light receiver 26 by way of optical cable 11, light distributor 34 and transmission line 12 and then the signal is transmitted to transmission reception logic part 29 via transmission line 19. This logic part 29 is to transmit the signal to S3 because of the signal of the S3 address, but since this station S2 is in process of transmission to S4 with wavelength lambda1, the received signal of station S1 with lambda1 os converted into a signal of wavelength lambda2 via transmission line 24, lambda2 light transmitter 31, transmission line 16, light synthesizer 35, and optical fiber 18 to transmit data to station S3.

Title: Thermal head
Inventor: YAGINO MASANORI
IPC: B41J2/335
Filed: 1987-01-23
Abstract: PURPOSE:To ensure that the heating value of a heat generating resistor part is greater on the higher side of an inclined recording surface, the surface temperature of the recording surface can be set substantially uniform, the shape of developed color dots on a thermal recording paper can be uniformized and printing quality can be enhanced, by setting the resistance of the heat generating resistor part to be gradually higher in the direction of increasing height of the inclined recording surface. CONSTITUTION:The rear side 1b of a substrate 1 is slantly ground so that it is sloped down toward a front edge and the thickness thereof on a heat generating part 2A is a predetermined value, thereby providing a recording surface 1b1. The heat generating part 2A is located on the front edge side of the substrate 1 at a position where the thickness of the substrate 1 is relatively small due to the presence of the inclination of the back side 1b, so that favorable heat transmission to the recording surface 1b1 is obtained. In addition, the resistance of the part 2A is set to be gradually higher toward the higher side of the inclined recording surface 1b1, so that the heating value is increased in the same direction. Therefore, though the recording surface 1b1 slantly corresponds to the heat generating part 2A, it is substantially uniformly heated, dots can be printed on a thermal recording paper with a fixed developed color density without increasing the electric power inputted to the part 2A, and power efficiency is enhanced.

Abstract: PURPOSE: To advantageously decode a digital multiplex signal by multiplying a digital type multiplex signal with a reference carrier wave mutually shifted by a specified angle and multiplying the obtained signal with a specified correction signal. CONSTITUTION: The digital multiplex signal MPX supplied with an input side 1 is multiplied with the reference carrier wave by multipliers 2, 3. In this case, multiplication by the multiplier 3 is performed by the reference carrier wave whose phase is shifted by 90 degrees to the multiplication by the multiplier 2. Output signals of the multipliers 2, 3 are supplied to multipliers 4, 5 and multiplied with the correction signal obtained from a circuit network 21. The output signals of the multipliers 4, 5 are added together by an adder 6, the output signal is regulated by a multiplier 7 and becomes a demodulated differential signal (L-R). The differential signal (L-R) is supplied to a matrix circuit consisting of adders 8, 9 with the multiplex signal MPX. Decoded digital stereo- audio signals L and R are outputted with low pass filters 10, 11.
