Title: Reader
Inventor: IZAWA TADASHI
IPC: H04N1/10
Filed: 1986-09-03
Abstract: PURPOSE:To prevent any type of unnecessary light that tries to enter a solid- state image pickup element and to obtain an excellent picture with a high contrast for a long period by providing a lens read unit with a light shielding case in which only an optical path part is opened. CONSTITUTION:An image pickup lens 21 and a prism 22 are firmly installed by a fitting member, etc. After solid-state image pickup elements C-ch CCD25 and R-ch CCD27 are position-adjusted at high accuracy with respect to the prism 22, the lens read unit 20 is integrally and firmly installed with an adhesive, etc. Antireflection treatment such as black painting is applied to the interior of the light shielding case 60. Thus the entire surface of the read lens unit 20 excluding its necessary optical path is coated, whereby almost all the unnecessary light that tries to enter from the gap between the image pickup lens 21 and the prism 22 or from the surface of the prism 22 can be prevented. The entire external surface of the image pickup lens 21 and that of the prism 22 are painted in black. Thus a small quantity of unnecessary light entering into the light shielding case 60 cannot enter the lens read unit 20, and simultaneously the inner reflection of said unit 20 can be prevented.

Abstract: PURPOSE:To obtain a stable semi-conducting layer side portion with little aging change by containing no oil in a semi-conducting layer and an insulator in a rubber stress cone integrally formed with the semi-conducting layer and the rubber insulator. CONSTITUTION:A rubber stress cone 1 is formed at the terminal connection section of a cable C to be connected, its inside is made of an insulator 2 and a semi-conducting layer 3. On the cable C side where this rubber stress cone 1 is formed, a cover is removed for connection, and a conductor 4 is exposed. Of course, no diffusion transition of oil occurs in the rubber stress cone managed to contain no oil in the semi-conducting layer and the insulator. No deterioration of the semi-conducting layer occurs, thereby high stability is obtained.

Title: Image processor
Inventor: OWADA HIDEO
IPC: H04N19/00
Filed: 1997-08-04
Abstract: PROBLEM TO BE SOLVED: To enlarge and reduce an image with a simple constitution by storing pixel information of the bottom row and rightmost column in an object block in a storage means and referring to information on stored pixels in the image processing of blocks adjacent to the stored pixel. SOLUTION: At the time of image reduction, a microblock of 16×16 pixels from an MPEG decoder 1 is temporarily held in a microblock memory 2 and then inputted to a video reducing circuit 3. At this time, a memory 7 for storage is stored with pixel information of the bottom row of each microblock a line ahead of a microblock being reduced by the video reducing circuit 3 in a 1st storage area, and pixel information on the rightmost column of a microblock just before the microblock being reduced by the video reducing circuit 3 in a 2nd storage area. When one of the top row or the leftmost column of the microblock is thinned out, the pixel adjacent to the thinned-out pixel can be complemented with the pixel stored in the 1st or 2nd storage area, so that the image can be reduced in the unit of block.

Title: Production of cyclopentadecanone
Inventor: MATSUMOTO MASAKATSU
IPC: A23L27/20
Filed: 1986-09-05
Abstract: PURPOSE:To produce the titled compound in high selectivity and yield, by successively adding a ketone to a reaction system composed of hydrogen iodide and an organic acid and reacting the components while constantly keeping the molar ratio of ketone/hydrogen iodide in the reaction system to a level smaller than the stoichiometric ratio. CONSTITUTION:A ketone of formula (X is OH and Y is H or X and Y together form one O) (e.g. 2-hydroxycyclopentadecanone) is successively added to a reaction system composed of hydrogen iodide and an organic acid (e.g. acetic acid) acting as an organic solvent and reacted with hydrogen iodidie while constantly keeping the molar ratio of ketone/hydrogen iodide in the reaction system to a level smaller than the stoichiometric ratio. The ketone is reduced with hydrogen iodide by this process to obtain cyclopentadecanone. The ratio of ketone/ hydrogen iodide is preferably 1/2 when ketone is 2-hydroxycyclopentadecanone and is preferably 1/4 when it is 1,2-cyclopentadecanedione.

Title: Radiation device, radiator, and radiation method
Inventor: FURUYA KANTARO
IPC: H01J23/00
Filed: 1998-07-24
Abstract: PROBLEM TO BE SOLVED: To improve radiation effect by allowing a heater and a radiator to adhere one another. SOLUTION: A projecting part 2 is formed while it projects from a surface where a traveling-wave tube 5 is placed and the side part is provided with a first inclination surface forming an acute angle on the placement surface. A cut-out part 3 is formed near a high temperature heater 1 of the traveling- wave tube 5 and has a second inclination surface with essentially the same inclination as the first inclination surface of the projecting part 2. The traveling- wave tube 5 is arranged on a radiator 4 so that the projecting part 2 is engaged to the cut-out part 3, and force in a direction marked by an arrow 9 is applied by a screw 7.  At this time, since the first inclination surface of the projecting part 2 and the second inclination surface of the cut-out part 3 are pressed to the placement surface in horizontal directions each other, the high temperature heater 1 is pressed against the radiator 4. Therefore, the high temperature heater 1 is allowed to directly adhere to the radiator 4, thus improving heat transfer and radiation effect.

Filed: 1993-08-02
Abstract: PURPOSE: To provide a method and a system with which a code is encoded into digital image, this image is monitored and it is judged whether that image is derivated from the encoded image or not. CONSTITUTION: These method and system are provided for embedding a code into the visible image of both digital display and print or film.

Abstract: PURPOSE:To inhibit the generation of saturation voltage minimally by forming N type emitter layer and collector layer having the same concentration and the same shape into a P type base layer and shaping a shallow P type low- concentration impurity layer to the surface of said base layer. CONSTITUTION:An N<-> type epitaxial layer 1 and an isolation diffusion layer 12 are formed to a P type Si substrate 10. A P<+> type base layer 13 and a P<-> type low-concentration impurity layer 14 having a surface area larger than the layer 13 and film thickness thinner than the layer 13 are shaped at approximately the center of the layer 11 in succession. An N<++> type collector layer 15 and an N<++> type emitter layer 16 having the same concentration and the same shape are formed deeply into the layer 13. An N<++> type high-concentration contact layer 17 is shaped brought into contact with the end edge of the layer 14 in an upper end in the epitaxial layer 11. Accordingly, junction areas between the layer 15 and the layer 13 and between the layer 16 and the layer 13 are made approximately the same while the concentration of the layer 15 and the layer 16 is equalized, thus minimally inhibiting saturation concentration.

Abstract: PURPOSE:To prevent the up and down motion of a needle bar with the turn of a needle bar supporting body in advance and to eliminate the change of a maximum stitch pitch by rotating and driving the stator of a needle bar driving motor in a direction to cancel the rotation of a planet rotary body. CONSTITUTION:When respective supporting bodies 5 and 23 are turned, the rotation of a supporting body driving shaft 33 is transmitted through respective pulleys 56 and 55, a belt 57 and a hollow shaft 53 to a stator 53a and the stator 51a is turned with being interlocked with the respective supporting bodies 5 and 23. Since a driving motor 51 is a servo motor, a rotor 51b is accelerated or decelerated and turned in correspondence to the turning direction of the respective supporting bodies 5 and 23 with following the stator 51a. Then, with the turn of the rotor 51b, horizontal shafts 12 and 24 in the respective supporting bodies 5 and 23 are turned in a direction to cancel the phase change of a needle tip in a needle bar 6 and a bobbin 25. Accordingly, even when the needle bar supporting body 5 is turned with the change of the feeding direction of working cloth C, the phase change of the needle bar 6 is not generated.
