Title: Method for encoding picture
Inventor: MASUNO TAKASHI
IPC: H04N19/423
Filed: 1994-03-25
Abstract: PURPOSE:To attain a picture encoding method with high picture quality even when a specific image effect is applied to a picture or a picture with cinema size is allocated to a current TV system by executing mosaic processing for an optional rectangular area in picture data and allowing a mosaic pattern boundary to coincide with a block division boundary. CONSTITUTION:A mosaic processing means 2 executes flattening processing for an optional rectanguar area in picture data by the number of picture elements whose one side is 2<n> (n is a natural number). In this case, address information to be applied to the means 2 is matched with the coordinate information of a block boundary divided by a block dividing means 4 and a mosaic coefficient also is indicated by a similar rectangular area. The same rectangular area processed by the mosaic processing is segmented also by the means 4 and its space redundancy is reduced by a DCT means 6. Thereby an effective DCT coefficient outputted from the means 6 becomes only a DC component, the number of bits required for encoding the part can be reduced, quantizing width to be applied to a quantizing means 7 is thinned, and the deterioration of picture quality can be suppressed.

Inventor: MOGI MASAHARU
IPC: F21V8/00
Filed: 1987-03-11
Abstract: PURPOSE:To easily monitor quantity of incident light by bundling plural pieces of optical fibers around an incident end, separating one of such fibers from the remaining optical fiber at the mid-point to an exit end and guiding the front end thereof to a monitor light exit end. CONSTITUTION:The light from a light source (not shown in the figure) is entered from the incident end 1 to each of plural pieces of the optical fibers and the greater part of the light is transmitted to the exit end 2. An object to be irradiated can, therefore, be subjected to sterilization by UV rays, etc., if said object is disposed in front of the exit end 2. On the other hand, part of the incident light is emitted via a monitor guide 4 and the monitor light exit end 5. A fluctuation or flickering in the quantity of the light emitted from the light source is, thereupon, detected if the monitor light is received by a sensor (not shown in the figure). Adequate constitution is thus permitted according to the type of the light source and the performance of the sensor.

Title: Semiconductor laser wavelength stabilizer
Inventor: AKIYAMA KOJI
IPC: H01S5/0687
Filed: 1986-03-13
Abstract: PURPOSE:To obtain a semiconductor laser wavelength stabilizer having a stable wavelength and narrow spectral band width by simple constitution by controlling the wavelength of a semiconductor laser so that the difference in detected output between two output beams from an absorption cell reach zero. CONSTITUTION:The titled stabilizer has a shift separating means PBS1 separating output beams from a semiconductor laser LD into two optical outputs having a predetermined frequency difference and an absorption cell CL, to which two output beams from the shift separating means PBS1 are projected and into which a substance generating absorption by a specific wavelength is sealed. The wavelength of the semiconductor laser LD is controlled so that the difference of the detection outputs of two output beams from the absorption cell CL reaches zero. Consequently, since the wavelength is controlled at a zero-cross point without using a locking-in amplifier, output beams are not modulated, thus narrowing spectral band width. Since the wavelength is controlled at the zero-cross point, the wavelength is stabilzied to a high degree, thus varying no wavelength at the zero-cross point even when the temperature of the absorption cell is changed and absorption is altered.

Title: Heat pipe
Inventor: NISHIYAMA MITAMI
IPC: F28D15/02
Filed: 1989-03-10
Abstract: PURPOSE:To interrupt a thermal transportation with a signal given from an external side or to enable a restarting of operation to be carried out by a method wherein a wick is formed by an electrical conductor near a clearance between a cooling part and a heating part and a closed container is made of an electrical insulation material. CONSTITUTION:As a switch 5 is turned on to apply a high voltage between clearances C, a working medium liquid composed of inductive substance is attracted toward the clearances C and the wicks 2A and 2B are approximately connected to each other. Liquid of working medium condensed at the cooling part B passes through the wick 2B, passes through the clearances C, passes through the wick 2A, reaches the heating part A, the heat of it is absorbed and then the liquid evaporates. As the switch 5 is opened, a voltage is not applied to the clearances C. The working medium liquid is transported to the clearances C under a phenomenon of capillary action. Capillary action is not produced at the clearances C, resulting in that the liquid may not pass through the clearances C. Thus, a thermal transfer through the heat pipe is interrupted. With such an arrangement, it is possible to facilitate a thermal transfer, a rapid shutting or a restarting operation.

Abstract: PURPOSE: To harden the substrate surface, by covering the surface of iron base substrate such as ordinary steel, tool steel and cast iron with Ni-P alloy and heating, then placing temporarily-sintered WC-Co green compact, further placing thereon mixed green compact of temporarily-sintered Ni-P alloy and TaC as infiltrating agent, and heating.  
     CONSTITUTION: The surface of iron base substrate such as ordinary steel, tool steel and cast iron is covered with Ni-P alloy by plating or other means, and is heated for 10W30min at 950W1000°C, in nonoxidizing atmosphere. A temporarily-sintered WC-Co green compact is placed on this film, and, as infiltrating agent, a mixed  green compact of temporarily-sintered Ni-P alloy and TaC (2W20%) is placed  thereon, and heated for a specified time. In this method, as compared with the  method of using only Ni-P alloy as the infiltrating agent, the hardness of the infiltrated surface is higher and the deformation of products is small, and the yield is  higher. Therefore, this method is effective for forming a hardened layer on the surface of members, such as mechanical seal ring and mold frame for press.

Abstract: PURPOSE:To make amplifications of light receiving signals even under transient conditions at the time of power source making, by changing the reference voltage following to the charging voltage of the coupling condenser at the time of power source making. CONSTITUTION:When, for example, an electric power is supplied from a battery 5 at a time t1 by turning on an ignition switch, the bias voltage of an inversional input terminal of an operation amplifier 2 which is fixed depending on the charging voltage of a coupling condenser C1, is changed at a charging time constant shown by a formula, C1(R1+R2+R3), and a light receiving pulse signal which changes as shown by a curve (a) is inputted. On the otherhand, a reference voltage Vref impressed upon a noninversional input terminal is also changed as shown by a curve (b) following to the curve (a) corresponding to the charging time constant (C2XR5) of a condenser C2. Therefore, the dead time between times t1 and t2 can be minimized to a negligible degree, and the light receiving pulse signal can be amplified even under transient condition of the circuit.
