Title: Optical fiber cable
Inventor: YOSHIDA NORIYUKI
IPC: G02B6/44
Filed: 1987-03-25
Abstract: PURPOSE:To prevent heating and burning of a protective resin tube by local scattered light generated from an optical fiber by providing a metallic layer on the outer circumference of the protective tube. CONSTITUTION:The metallic layer 3 is provided around the protective resin tube 2. This layer may be formed by winding metallic foil around the tube. The metallic foil is wound on the tube 2 in a manner as to avoid generating gaps between the foil and the tube. The role of the metallic layer 3 is to increase the heat conductivity of the tube 2 and in this sense the result is better as the thickness of the metallic layer is larger. The winding of the metallic foil necessitates spiral winding and, therefore, resilience is hardly lost even if the foil is slightly thick. The heat conductivity in the axial direction of the tube is increased by providing the metallic layer 3 to the outer circumference of the tube 2. The point where laser light falls is just a point U even if the laser light leaks from the fiber and falls strongly on one point U of the protective resin tube. A local rise of the temp. is thus obviated.

Title: Picture coding processing method and picture decoding processing method
Inventor: NAKANISHI HIDETOSHI
IPC: H04N19/93
Filed: 1992-02-20
Abstract: PURPOSE:To prevent deterioration in a required object picture while reducing quantity of picture data. CONSTITUTION:Data of an original picture are divided into picture element blocks by a picture element block division section 2, and a picture element block discrimination section 4 classifies the picture element blocks into a contour block group, an object block group and a non-object block group based on given contour data. As to picture data of the former two picture element block groups, 1st and 2nd compression sections 5, 6 compress the data at a low compression rate and a 3rd compression section 7 compresses the non-object block group at a high compression rate. Thus, while keeping the picture quality of the important picture sharp, the quantity of the picture data is reduced more than a conventional method low-compressing the entire picture quality. Thus, while keeping the picture quality of the required picture sharp, the quantity of the picture data is remarkably reduced.

Title: NiTi-TYPE SUPERELASTIC LINEAR BODY ELEMENT, AND PRODUCT USING THE SAME
Inventor: SHIROYAMA KAISUKE
IPC: C22C19/03
Filed: 1999-03-17
Abstract: PROBLEM TO BE SOLVED: To minimize deterioration in flexural rigidity and to attain weight reduction by forming the cross-sectional shape of a linear body into a practically equilateral- hexagon shape and regulating the bend radius of the vertical angle of the hexagon to a specific value. SOLUTION: In the cross section of a linear body 1 having a practically equilateral- hexagon shape, the bend radius(r) of the vertical angle of the hexagon is regulated to 0.25R to 0.60R based on the radius R of a circumscribed circle of the cross section. As compared with a wire having a circular cross section, this linear body 1 can attain weight reduction by about 10% and can improve durability to cyclic bending by about 30%. Although bending rigidity becomes decreased by about 10%, equivalent bending rigidity can be provided by using a material increased in yield strength by about 10%. Polygons of pentagon or below are not adopted because, when they are adopted, reduction of area becomes increased and deterioration in properties such as bending rigidity becomes increased and, as a result, plastic working of the end part as well as manufacture becomes difficult.  Moreover, the bend radius(r) of the vertical angle of the hexagon is regulated as mentioned above in order to improve touch and to prevent the hindrance of durability to cyclic bending.

Title: Video signal processing unit
Inventor: NAKAKUKI TOSHIAKI
IPC: H04N11/04
Filed: 1997-03-26
Abstract: PROBLEM TO BE SOLVED: To allow the processing unit to be compatible with the NTSC system and the PAL system, to suppress the scale of circuit configuration and to prevent frequency interference by multiplying medium value data with each of color difference signal data, selecting data and adding data based on a clock pulse whose frequency is 14.1875MHz. SOLUTION: An R system processing block 21 multiplies medium value data with red component color difference signal data RY to respectively obtain Ra-Rc and Rd being color difference signal data. The data are given to a selection output circuit 211, from which the data are selected and outputted based on the output of a hexadecimal counter 23 receiving a clock pulse whose frequency is 14.1875MHz. Thus, the output value is similarly processed by modulation with a chrominance subcarrier whose frequency is 4.43MHz. In a B system processing block 22, similarly data BY are modulated by selection output circuits 221, 222. The two kinds of modulated data are added by an adder 24 to obtain chrominance carrier signal data whose frequency is 14,1875MHz. Thus, the scale of circuit configuration is suppressed and longitudinal stripe noise due to frequency interference is suppressed.

IPC: G03B13/36
Filed: 1979-06-12
Abstract: PURPOSE: To enable the photographer to concentrate on setting of composition by so constituting the device that the operation of engaging the focus lock is made simple, it is made sustainable even if this state is not fixed by the finger and this state is made freely releasable.  
     CONSTITUTION: Beforehand, a film winding lever 23 is turned right within the range of a preliminary angle. Next, when a release member 1 is pushed down by a release button 2, an automatic focusing mechanism actuates on its way. The protruding part 15 of a lever 13 then goes under the protruding part 7 of a lever 5. Even if the depression of the release button 2 is released from this state, the protruding part 7 of the lever 5 engages onto the protruding part 15 of the lock lever 13 to prohibit the turning and resetting of the lever 5. In addition, the pin 3 of the release member 1 engages with the protruding piece 10 of the lever 5 to prohibit the resetting of the release member 1, thus the automatic focusing mechanism is locked while focused. If in this state the winding lever 23 is turned right within the range of the preliminary angle, the automatic focusing mode may be released.

Abstract: PURPOSE:To absorb difference in thickness between the respective components of a separator and a unit cell so as to improve the thickness and dimensional accuracy of a layer built fuel cell by forming an edge plate in a thin and long- sized one. CONSTITUTION:In a layer-built fuel cell, an edge plate 20 coming in contact with the outside edge section of each unit cell to form an outside frame for the flow passages of both an fuel gas and an oxidizer gas is formed out of a thin plate, then a flat section 20C is formed between the part 20a of the edge plate 20 coming in contact with an interconnector 6 and a part 20b thereof coming in contact with an electrolytic matrix, so that the edge plate 20 is formed in flexible structure, and by elasticity of the edge plate 20, the inside circumferential edge section thereof is accordingly stuck to the outside edge section of each unit cell when the cells are stacked upon one another. Thus differences in thickness between the respective parts of each unit cell caused when the fuel cell is manufactured can be absorbed by deformation of the edge plate so that the thicknesses of the parts is equalized, and the contact between the electrolytic matrix and the edge plate 20 can be kept in excellent condition to prevent the reaction gases from leaking out of the fuel cell.
