Patent JP-S645086-A (JP)
Title: Optical repeater
Inventor: AOKI EIJI
IPC: H01L31/14
Filed: 1987-06-29
Abstract: PURPOSE:To reduce a dispersion penalty by a method wherein the discrepancy between the wavelength of the output light of a laser diode and the zero- dispersion wavelength of an optical fiber cable is detected and the wavelength of the output light is controlled in accordance with the detected discrepancy. CONSTITUTION:The light output of an emitted light wavelength control type laser diode 6 is divided into an output light and a branched light to a wavelength detecting control circuit 8 by an optical divider 7. The wavelength detecting control circuit 8 detects the discrepancy between the wavelength of the branched light and the predetermined zero-dispersion wavelength of the optical fiber cable of a transmission line and changes the emitted light wavelength of the laser diode 6 so as to make the discrepancy zero. With this constitution, the wavelength of the output light of the emitted light wavelength control type laser diode 6 agrees with the zero-dispersion wavelength of the optical fiber cable constituting the transmission line regardless to the temperature characteristics so that the dispersion penalty can be reduced.

Filed: 1982-09-17
Abstract: PURPOSE:To set the ignition timing at the critical point, where knocking is generated, by changing the value of angle in advancing or delaying the timing in accordance with the distribution of the proportion of knocking generations in respective cylinders. CONSTITUTION:In order to measure how often knocking has occurred in each cylinder, the count one is added to the current measurement of knocking generation (lj) for each cylinder in which knocking has occurred at Step 1511, and the frequency of knockings are counted for each cylinder.

Filed: 1995-06-07
Abstract: PURPOSE: To judge whether or not information provided by a user when it is displayed and outputted is the latest one by storing a reception date with a program content when a program whose reservation is registered is received. CONSTITUTION: When the program whose reservation is registered is received, a controller 6 samples the content of the program by a code sampling part 5, and fetches the present date information obtained from a clock part 10 at that time.

Title: Address-change detection circuit
Inventor: IKEBE MASAZUMI
IPC: G11C11/41
Filed: 1992-06-23
Abstract: PURPOSE:To adjust ATD characteristics over a wide range of power-supply voltage and to prevent that an operating characteristic on the side of low voltage is deteriorated by a method wherein the delay or the pulse width of an ATD circuit is changed over according to whether the power-supply voltage is high or low. CONSTITUTION:When the output D of a power-supply voltage detection circuit 1 is at a low potential 'L', an N-channel transistor T1 is turned off and a capacity element C3 is not connected. As a result, the delay time A1 from an inverter circuit I1 up to an inverter circuit I4 is small. When the output D is at a high potential 'H', the transistor T1 is turned on. The capacity element C3 is set to a connection state, and the delay time A1 from the inverter circuit I1 up to the inverter circuit I4 becomes large. Consequently, the pulse width of the output P of an address-change detection circuit 2 can be changed by the output D of the power-supply voltage detection circuit 1.

Title: Magnetic recording medium having shallow streak and its production
Inventor: RIN SEITOKU
IPC: G11B5/73
Filed: 1998-06-11
Abstract: PROBLEM TO BE SOLVED: To enhance the surface flatness of a disk substrate surface and to facilitate the control of the shapes and sizes at the time of forming streaks with a laser by subjecting the substrate to a micropolishing treatment twice and removing the abnormal projections and oxide layers on the substrate before the formation of the streaks with the laser. SOLUTION: The substrate 20 is rotated clockwise at 150 rpm and about 1 pound pressure is applied on the substrate by a polishing belt. The substrate is vibrated at 2 mm amplitude and is polished for 6 seconds by injecting a diamond slurry of about 1 μm in diameter. As a result, the intersection included angles of the shallow streaks engraved in a circumferential direction of 6 to 8 deg. in a substrate 20 landing zone 23, 4 to 6 deg. on the inner periphery 201 of a data storage area 21 and 2 to 4 deg. on the outer periphery 202 are formed. Next, the rotation of the substrate 20 is changed to counterclockwise rotation and is subjected to the similar treatment, by which the substrate 20 having the shallow streaks and surface roughness 8 to 12 Å is produced.  The abnormal projections on the surface of the substrate 20 and the oxide layers by long-term resting may be removed by two times of the micropolishing treatment. The control of the sizes and shapes at the time of formation of the streaks with the laser is thus facilitated.
