Title: Encoding system for picture signal
Inventor: MIURA TSUNEHIRO
IPC: H04N19/91
Filed: 1989-04-05
Abstract: PURPOSE:To improve the encoding efficiency without deteriorating the information compressing effect by encoding with variable length a DC component and plural conversion coefficients rearranged in a 1-dimensional form for production of codes. CONSTITUTION:The different scan conversion tables 104 are used for each class to perform the scan conversion of plural conversion coefficients 105 except a DC component. As a result, the coefficients 105 can be rearranged in each block so that the significant coefficients are continuous and the length of zero run is increased. Receiving an outputted table 104, a scan conversion part 5 scans and converts plural coefficients 105 for each block except the DC component received from a 2-dimensional discrete cosine DCT conversion part 2. Then the part 5 outputs plural conversion coefficients 106 rearranged in a 1-dimensional form and encodes with variable length these coefficients 106 and the DC component of each block to output a code 107. The same classing operation is carried out with use of the value of a DC component 103 even in a decoding state. As a result, the coefficients 105 can be correctly decoded except the DC component of each block.

Title: Back raster controller for cathode ray tube
Inventor: WAKABAYASHI SHUNJI
IPC: H04N5/14
Filed: 1990-03-30
Abstract: PURPOSE:To always make the brightness of back raster almost constant regardless of load fluctuation by controlling a power voltage in response to an output change of a high voltage generating circuit and using the output voltage for a power voltage of a video output circuit. CONSTITUTION:When a contrast of a screen of a CRT 1 is decreased, since a load of a flyback transformer is lighted, a grid voltage and an anode voltage generated from a high voltage generating circuit 6 get higher, then a detection signal (voltage) of a detection means 17 is higher, resulting that a regulator output voltage obtained from a transistor(TR) 21 controlled by a collector current IC, that is, a power voltage +B resulting from controlling a power voltage +B1 is higher. When the contrast is increased, an output voltage of the high voltage generating circuit 6 is decreased and the detection signal of the detection means 17 is decreased. Thus, a current IB is increased and a current 1C is increased. As a result, the regulator output voltage, that is, the power voltage +B resulting from controlling a power voltage +B1 is lower.

Filed: 1995-03-20
Abstract: PURPOSE: To enhance the efficiency of a lamp by fixing a spheroidal glass sleeve in which both ends of a filament are adopted as a focal point to a filament lead wire by a mounting body and forming a multilayer interference film on at least one of an inner and an outer surfaces. CONSTITUTION: A glass tube 1 having a tip-off part 1a as a closing part at one end and a sealing part 2 at the other end part is internally provided with a filament 3 covered with a spheroidal glass sleeve 4. A multilayer interference film 9 is formed in at least one of the inner and outer surfaces of the sleeve 4, and the sleeve 4 is fixed to lead wires 7, 8 in the straight tube parts of both ends through mounting wires 5, 6 so that both ends of the filament 3 accord with two focal points of the oval body. The lead wires 7, 8 are fixed by a stem glass 10 and a base 11 is provided in the sealing part 2. Since the interference film 9 passes visible light from the filament 3 and reflects infrared ray toward the focal points, the temperature of the filament is raised, so that luminous efficiency may be enhanced.

Title: Optical apparatus
Inventor: TORIGOE MAKOTO
IPC: H01S3/10
Filed: 1986-04-16
Abstract: PURPOSE:To reduce the luminous power of a deleterious pedestal light only to a half and improve resolution by a method wherein a polarizer is provided on the emitted light axis of a laser device which is injection-locked. CONSTITUTION: The polarization of a polarizer 12 such as Grant-Thomson prism or a dielectric film polarizing beam splitter is so adjusted as to make the light of the polarization coincide with the polarization of the oscillator of a laser 11 transmitted. A narrow-banded linearly polarized laser beam is generated by the oscillator A of the laser 11 and amplified by the amplifier B of the laser 11 and emitted. As the laser beam, which enters the polarizer 12, is a linearly polarized light, the laser beam can be totally transmitted through the polarizer but, as a pedestal light generated in the amplifier B is not polarized, only a half of the pedestal light can be transmitted. Therefor, the ratio of the luminous power of the pedestal light to the total luminous power of the emitted light after transmitting through the polarizer 12 is a half of the luminous power ratio before transmitting through the polarizer 12 and locking efficiency can be improved by that much.

Abstract: PURPOSE:To carry out highly precisely position detection by way of preventing reciprocal interference by means of radiating a reflected diffracted light in the direction different from that of a transmitted diffracted light by forming a sectional shape of a second scale in the perpendicular direction in a wedge type. CONSTITUTION:A parallel light Lb coming in a first scale 13 goes out as a transmitted diffracted light after transmitting (a) (b) faces, coming in a second scale 114, transmitting a (c) face as it is and refracted through a (d) face. Subsequently, the light is reflected on the (d), (c) faces and refracted through the (d) face again, and it goes out as a reflected diffracted light Lrc. Thereafter, the diffracted light Lc is received by a photoelectric transfer element 15 and transferred to an electric signal equivalent to displacement of the first scale 13, but the diffracted light Lrc is not received but it is radiated out of a system. Consequently, it is possible to obtain a stable displacement signal by way of separating the diffracted light Lrc which causes change of diffraction strength by means of causing interference with the diffracted light Lc.
