Abstract: PURPOSE: To increase mechanical strength with a light output surface thickened, and to extract light efficiently by making large a spreading angle of the light, arriving at the light output surface from the luminous layer, through the lens effect of the dome-shaped light output surface.  
     CONSTITUTION: In N-type GaAs substrate 1 of surface (100), dome-shaped hole 11 is formed by being selectively etched, and on the entire surface including this, N-type Al 0.3 Ga 0.7 As layer 2 and P-type Al 0.1 Ga 0.9 As luminous layer 3 are stacked and the liquid-phase epitaxial growth of them is done. On it, P-type Al 0.3 Ga 0.7 As layer 4 and P-type GaAs layer are grown. By selectively etching the reverse surface of substrate 1, concave part 11 on the reverse surface of layer 2 grown in hole 11 is exposed, thereby forming light output hole 10. Next, N-type electrode 8 is adhered to the reverse surface of substrate 1 encircling hole 10, and P-type electorde 7 is to the surface of layer 5 at the opposite side via SiO 2  film 6 with window 9 confronting to light output surface 11. Consequently, externally luminous efficiency improves because of the dome shape of the light output surface.

Title: Information signal reproducing device
Inventor: HORI MASASHI
IPC: H04N5/92
Filed: 1989-06-07
Abstract: PURPOSE:To contrive the accurate reproducing by restoring an information signal by using an FM demodulation signal after a prescribed time from an instruction made for commencing a reproducing operation. CONSTITUTION:When the reproducing operation is instructed to start by a control circuit 8, a magnetic head 3 reaches onto a target track, and the standby state is effective for a prescribed time. Then after a lapse of the prescribed time, a regenerative signal from the head 3 is demodulated by an FM demodulator 5, and its output is supplied to the circuit 8 via a deemphasis circuit 10 and an A/D converter 11. A control code is detected from this signal by the circuit 8 to discriminate the recording state. By this method, after a DC potential fluctuation of a signal to be supplied from the demodulator 5 to the converter 11 is stabilized, the presence of the control code is decided, and hence the accurate reproducing can be performed.

Title: Method and apparatus for supporting optical reading head
Inventor: RODONII ESU RIBUINGUSUTON
IPC: G11B7/08
Filed: 1983-08-12
Abstract: Method and means for supporting an optical read or write head to maintain a constant spacing between the head and a moving information storage medium. A major drawback in the prior art head assemblies incorporating pheumatic forcing pistons concerns the chattering, or lateral and axial vibrations, of the lens assembly relative to the housing due to the turbulent airflow in the passageway leading from the annular chamber to the atmosphere. The present invention provides a lens assembly/housing arrangement in which substantial axial support for the lens assembly within the housing is obtainable simultaneously with eliminating the turbulent air flow by increasing the axial width verses gap width ratio. Basically, the invention involves an annular pressure chamber provided between air journal bearings at each end of the housing. Air pressure in the annular chamber is regulated to provide a stable but variable biasing force on the inner lens assembly relative to the housing in a direction opposite that of a relatively fixed opposing biasing force.

Title: Optical transmitter, optical communication system and method for amplifying optical signal
Inventor: SUYAMA MASUO
IPC: H04B10/079
Filed: 1996-06-10
Abstract: PURPOSE: To control a level of an output optical signal by modulating a stimulated light with a high frequency wave with a processing frequency so as to use monitor information of an optical fiber amplifier enabling transmission of the stimulated light. CONSTITUTION: When a transmission instruction of monitor information is received by an incoming repeater 18, a controller 46 controls a modulation circuit 48 based on outgoing monitor information from a signal processing circuit 44 to apply intensity modulation to a stimulated light from an exciting power supply 30. The modulation speed in this case is sufficiently higher than a reciprocal of a life of a fluorescent light of a rare-earth doped fiber 28, that is, the monitor information is sent as a carrier for a stimulated light almost without the modulation component in the signal light sent to the incoming repeater by modulating the stimulated light with a high frequency signal whose period is almost shorter than the life of the fluorescent light in the stimulated state.  Furthermore, based on the monitor information, an automatic output level control circuit APC 40 controls power of the stimulated light to control an output signal level constant independently of a level of an input optical signal.

IPC: G06F11/22
Filed: 1987-06-11
Abstract: PURPOSE:To check the content of a control register before and after power- down in a short time without increasing number of instructions for the required number or over by sending a data written in the control register before power- down to a data bus from an accumulator again and detecting the coincidence of a data coincidence detecting means inbetween. CONSTITUTION:A prescribed data (e.g., D1) is written in the control register 3 via a data bus 2 by an accumulator 1. Then the microcomputer is forcibly subjected to power-down and then restored. Then the data D1 is sent from the accumulator 1 to the data bus 2 synchronously with the leading of a clock phi1 at a time t1 again. The control register 3 holds the data before power-down (D1 when normal) at times t1-t2. Thus, the data change in the control register 3 is checked by detecting the coincidence of the data stored in the control register 3 with the data on the data bus 2 during the times t1-t2.

IPC: G11B21/10
Filed: 1985-07-03
Abstract: PURPOSE:To reduce power consumption by opening a servo loop when the absolute value of a carriage drive voltage is a prescribed voltage or below so as to prevent a drive current from flowing at the dead band of the carriage motor and short-circuiting the carriage motor. CONSTITUTION:When a drive is within a range of +Vref--Vref in a carriage servo circuit 114, since an output of an OR gate 123 is at a low level, a loop switch 120 is turned off, that is, the servo loop is opened. Since no drive voltage is given to a 2-way drive circuit 122 when the drive voltage is within the range of +Vref--Vref, a small current not contributing to the start of a motor 51 does not flow, the motor 51 is short-circuited by a transistor Q being in on-state and the rotor of the motor 51 is locked.
