Filed: 1987-02-13
Abstract: PURPOSE:To permit easy detection of a reference point and to simplify production of a recording medium by imposing an annular mask and small toric mask having partly a projecting part on a substrate and depositing a recording layer having no recording layer in part on the inside circumferential side on the substrate. CONSTITUTION:The mask 16 which has the outside diameter equal to the outside diameter of the substrate 11 and the inside diameter equal to the outside diameter of the toric information recording layer 12 and the mask 17 which has the outside diameter equal to the inside diameter of the recording layer 12, has the partly projecting part and has the inside diameter coincident with the inside diameter of the central hole 14 of the substrate are respectively imposed on the substrate and a reflection material is deposited by evaporation on the surface of the substrate to form the recording layer 12. The outside diameter of the recording layer is slightly smaller than the outside diameter of the substrate and the toric part 15' partly notched with the partly projecting part 13 is formed on the inside diameter side. The reflection state changes at the time when the light passes the projecting part 13 if the light is projected to the toric part 13'. The easy detection of the reference point is, therefore, permitted and the production of the recording medium is simplified.

Abstract: PURPOSE:To give a sufficient performance to a system using floppy disk devices by inserting a processor between a host machine and a floppy disk device and accessing a memory part at a high speed. CONSTITUTION:When loading of a program to an area #0 of a memory part 6 is completed, a processing part 7 sends the signal, which indicates the first floppy disc FD device for program is ready, to a host machine 1 through an FDD interface part 9.

Filed: 1989-02-09
Abstract: PURPOSE:To execute a long distance transmission by using a balance transmission system being immune to noise between an unbalance/balance conversion unit of a fundamental base part and an unbalance/balance conversion unit of each extended base part. CONSTITUTION:In the case of transferring the data to an extended base 2 from a fundamental base 1, a data signal and various control signals on an I/O bus of the fundamental base 1 are sent out onto a data bus 32 and onto an output signal line 16a of a control bus through an I/O bus connecting connector 11. Subsequently, when a gate control circuit 20 generates a gate enable signal to a line driver 14 and a line driver 17, these data signals and control signals are converted to differential signals from single signals, respectively, and sent to a connector 7. Therefore, on an I/O extension cable 8 for connecting the fundamental base 1 and the extended base 2, these data signals and control signals are transmitted in parallel by a balance transmission system. In such a way, a long distance and high speed transmission can be executed.

Title: Amplifier
Inventor: YAMAZAKI YOSHIHIKO
IPC: H03F1/32
Filed: 1982-02-26
Abstract: PURPOSE:To compensate a decrease in the current amplification factor of an output transistor (TR) which is connected on push-pull basis to perform class ''AB'' or ''B'' operation, by connecting a by-passing means which operates in case of an increase in output current in parallel to an output resistance. CONSTITUTION:A transistor (TR) Q1 constitutes a voltage amplification stage and TRs Q2-Q5 constitute an output stage. The output stage consists of the driver-stage TRs  Q2 and Q3 and power-stage TRs Q4 and Q5. A constant current source CI supplies a bias current to the TRs Q2-Q5. Between the emitters of the TRs Q4 and Q5, resistances RE1-RE4 are connected in series and the connection middle point B is an output middle point. Further, a diode D0 is connected to the RE1 and RE2. Thus, a current by-passes an output resistance through the diode D0 in case of an increase in output current to reduce a voltage drop across the output resistance. Thus, a decrease in the DC current amplification factor of the output TRs is compensated to reduce distortion.

Abstract: PURPOSE:To produce wear-resistant parts having a smooth surface and long life at a relatively low temp. by sputtering a target of carbon by an ion beam and forming a vapor deposition film contg. carbon on the surface of a substrate installed in parallel with the ion beam. CONSTITUTION:The ion beam 22 of an inert gas such as Ar generated from an ion beam source 21 is irradiated on the carbon target 23 consisting of graphite, etc. to sputter the target. The surface of the substrate 11 which receives a physical effect of pressure, etc. is installed approximately in parallel with the above-mentioned ion beam 22 and while the ions are irradiated on said surface, the vapor deposition film contg. carbon is formed thereon preferably to >=1,000Angstrom . The smooth and highly wear-resistant film is formed by the above- mentioned method. Since the film can be formed at a low temp., the substrate such as plastic having <=200 deg.C softening temp. and an easy tendency to deformation at a high temp. is usable. The additional improvement in the adhesiveness of the film is possible by providing a buffer layer consisting of TiN, etc., between the above-mentioned substrate 11 and the film. The high effect is obtd. if hydrogen or hydrocarbon is mixed with an inert gas as the ion beam 22.
