Filed: 1995-02-13
Abstract: PURPOSE: To prevent a recording light pulse output from fluctuating due to return light by sampling a bias light level when high frequency superimposition being a recording rest section between recording pulses is turned off and controlling so that the bias light level becomes a target value. CONSTITUTION: In a bottom level part/recording level part 16 a sample and hold circuit 12 operating only when the high frequency superimposition to a laser drive circuit is turned off samples bias light by a bias current by a backward or forward monitor 11, and the bias light is compared with the setting bottom power of the target value by a differential circuit 13. Then, the monitored bias light is feedback-controlled so as to become the target value, and it becomes a low power state in a recording rest period, and such a situation that a laser output is affected by the return light, is prevented, and no temp. distribution on a disk by recording irradiation is changed, and the lowering in an S/N due to dispersion of a recording mark is suppressed.

Abstract: PURPOSE:To correct distortion of an optical image in the horizontal direction produced in an image pickup lens and a color separation prism and to obtain a highly accurate image pickup device without color shear by driving individually plural solid-state image pickup elements. CONSTITUTION:When an optical image on an image pickup face of a solid-state image pickup element 23 is distorted due to an optical system such as an image pickup lens 1 and a color separation prism 2 with respect to an object in which white stripes arranged on a black background at an equal interval, an electric signal is stored on the image pickup face of the solid-state image pickup element 23 corresponding to a scanning line L1-L2. A drive timing control circuit 29 controls the oscillated frequency of an oscillation section 26 of a drive signal generating circuit 26 to vary the drive speed. When the scanning direction of the scanning line L1-L2 is L1 L2, the output of the drive timing control circuit 29 is varied and the solid-state image pickup element 23 is driven at a low speed near the start of scanning, the signal is read at a low speed and driven at a high speed near the end of scanning to read the signal at a high speed. Thus, the signal outputted from the solid-state image pickup element 23 has no distortion in the optical system and the picture is made coincident with a picture of the object.

IPC: G06T5/00
Filed: 1999-02-02
Abstract: PROBLEM TO BE SOLVED: To provide an image processor for surely expressing an image having a half tone in a wide concentration range with desired specified characters. SOLUTION: An ROM 12 stores a 8×8 basic matrix constituted of, for example, 1-64 thresholds, font pattern data in which the character pattern of a specific character (for example, 'A') is indicated by sexadecimal, and a threshold address table in which thresholds in the basic matrix are arranged in the order of small size.

Patent JP-S50143490-A (JP)
IPC: G01S13/78
Filed: 1975-02-28
Abstract: A system for radar station identification depends primarily upon the encoding growing out of a pulse repetition rate of interrogation pulses. To secure the encoding, one or more pulses arm the system and succeeding pulses must be detected during an extremely narrow time of acceptance. Hence, the pulses are logically interpreted in order to reject randomly occurring stray signals.

Title: He-cd ion laser device
Inventor: KAWASE HIROMI
IPC: H01S3/03
Filed: 1988-02-05
Abstract: PURPOSE:To assure a long service life of the subject laser device by disposing a conductive material highly resistant to sputtering on the edges of transparent holes provided through a cathode and employing a nickel or a nickel alloy as a cathode material. CONSTITUTION:For a hollow cathode 3 provided coaxially with a laser tube 1, there is employed nickel or nickel alloy, e.g., Inconel. A material 14, which is electrically conductive and resistant to sputtering, is disposed annularly along the edges of transparent holes 4 through the hollow cathode 3 corresponding to respective main anodes 6. He atoms and He ions excited in a bore 11 interact with Cd atoms to produce a population inversion distribution between lasing levels of a Cd ion for the onset of lasing. Thereupon, the Inconel as a cathode material has a high work function and is liable to make alloy with Cd. Accordingly, when the inner wall of the bore 11 through the cathode is exposed to the atmosphere of Cd vapor, the Inconel produces an alloy with Cd on the inner wall of the bore 11. The resulting alloy is highly resistant to sputtering. Thus, less sputtering product is formed, without being deposited in the bore 11, thereby assuring a long service life of the laser tube.

Title: Decoder circuit
Inventor: KONDO TOMOJI
IPC: G11C11/34
Filed: 1987-02-05
Abstract: PURPOSE:To restrain two decode signals from being outputted at a time, and to improve product reliability by latching signals inputted to plural input terminals and outputting an inverted signal and a non-inverted signal and simultaneously delaying the leading edge of one signal behind the trailing edge of the other signal. CONSTITUTION:In each of plural latching circuits constituted of R-S type flip flop circuits 17, 19 and invertor circuits 18, 20 respectively, the inverted signal and the non-inverted signal of an input signal are generated to one input signal. Then, since they are outputted while delaying the leading edge of one signal behind the trailing edge of the other signal, the two signals never go to an H level at a time, and as a result, two signals among the output signals of decode circuits 21-24 obtained through a logic operation do not go to an H level signal at a time. Thus, when it is used as the address decoder circuit of a memory circuit, two word line selectors or two bit line selectors are never selected at a time, and the produce reliability is improved.
