Title: Tomography method and apparatus
Inventor: ARUTO BUIRUTA
IPC: A61B6/14
Filed: 1992-02-13
Abstract: PURPOSE: To achieve a tomography by a fine beam which is aimed at so as to advance to a mobile X-ray film F via an object to be radiographed by X rays. CONSTITUTION: An object P is held static at a certain position while an X-ray source and a film cassette (14) turns about an imaginary rotation axis A-A. In the first working mode of a panoramic type radiographing of a dentition, a patient is supported by a positioning means so that a clear imaging tissue surface P-P is positioned between the virtual rotation axis A-A of an X-ray image and the surface F of a film. In the second working mode of radiographing in the transverse projection of the dentition, the patient is supported at a static position so that the virtual rotation axis A-A of the X rays is positioned in a zone between the clear imaging tissue surface P-P and the film surface F. In the second working mode, the film F is moved in the direction opposite to the direction of transferring the film in the first working mode.

Title: Press die capable of upward and downward bendings
Inventor: UMEMURA SHIYOUJI
IPC: B21D5/01
Filed: 1982-02-22
Abstract: PURPOSE:To bend a material upward and downward in both directions, by attaching a downward-bending blade to an upper die to be capable of changing its upper and lower positions against the die and a upward-bending blade to a lower die freely movably in the vertical directions, and making a pushing member provided to the upper die push the downward-bending blade upward. CONSTITUTION:When a material W to be worked is set to the prescribed position on a punch 2, and an upper die 3 is lowered, a pad 4 is abutted first to the material W to hold and fix it with the aid of the punch 2. In this state, the edge part of material W projects a little to the side of each bending blade 5 and 6. When the die 3 is lowered further, the downward-bending blade 6 is pushed down to the lower limit position by an adjusting plate 10, and the downward bending of a flange is performed because the lower end of the blade 6 is positioned below the lower surface of the pad 4 locating at its upper limit position. Further, when the plate 10 is taken ut from between the die 3 and the blade 6 by retreating it, and the die 3 is lowered after interposing an adjusting block 15 between a push rod 12 and the die 3, an upward-bending blade 5 is pushed up by a lever 13 to perform the upward bending of the flange.

Title: Ink jet recording device
Inventor: KOMAI HIROMICHI
IPC: B41J2/01
Filed: 1989-02-06
Abstract: PURPOSE:To make possible the recording of a low-output semiconductor laser by providing a layer of liquid not to be used for recording and a layer of liquid to be used for recording in a liquid chamber and using hot-melting ink which becomes solid at normal temperature and liquid when heated as a liquid layer. CONSTITUTION:A laser beam is condensed on a surface between a glass substrate 4 and a recording liquid 7 with an absorption spectrum in the wavelength of a semiconductor laser 10 due to a coupling lens 9 and an objective lens 8. If the thickness of a liquid layer of a recording liquid 7 is about 20 to 30mum, a liquid column 5 generates following the drive pulse of the semiconductor laser 10. The liquid chamber consists of the first liquid layer 12 and the second liquid layer 13 which is thinner than the former as a dual layer structure. An oily liquid with low optical absorption not to be used for recording is used as the first liquid layer 12, and a water ink with high absorption coefficient which is about scores of mum thick is used as the second liquid layer 13. Thus the thin layer to be used for recording can be easily formed, and a low-output semiconductor laser can be used for generating a stable liquid column and applying it to recording.

Title: Sheets and boards, onto which amorphous ceramic layer is printed, and manufacture thereof
Inventor: UCHIDA MAKOTO
IPC: D06M101/16
Filed: 1989-02-06
Abstract: PURPOSE:To make agreeable to the touch of amorphous ceramic layer by a method wherein amorphous ceramic powder particles are covered with foamed resin. CONSTITUTION:Amorphous ceramic powder, paste-like foaming resin, paste-like binder resin, feeding water and other necessary assistants are mixed together. The resultant paste-like mixture is raised-printed on the surface J of sheets and boards H. The sheets and boards H, on which said mixture is printed, are pre-dried so as to prevent coarse surface from developing in the next foaming process under pressure due to abrupt evaporation of moisture. Next, foaming resin is expanded by pressurizing the surface of the printed and pre- dried mixture so as to make the surface smooth and the amorphous ceramic powder particles are covered with foamed resin. After that, by heat-treating, the amorphous ceramic layer F is bonded by binder resin to the sheets and boards H, resulting in obtaining the sheets and boards, the touch of which is agreeable.

IPC: H01L31/02
Filed: 1988-02-09
Abstract: PURPOSE:To eliminate the need for relative position adjusting mechanism and to simplify the constitution by using a refractive index distribution lens array made of a plastic as an optical system for a compound eye forming a unmagnification erected image of an original face and deciding the operating distance so as to adhere the lens end face with the transparent mount base of an unmagnification image pickup element. CONSTITUTION:A plastic-made lens array 101 having an operating distance l0 equal to the sum of the optical thickness of a transparent mount base 103 and the optical thickness of the base of a solid-state image pickup element 102 is adhered closely to the transparent mount base 103. Then the array 101 is adhered closely to the original face glass 105 by using the original glass 105 having an optical thickness equal to the distance l0. Since the distance l0 is selected normally to be 4mm or below, the lighting luminous quantity loss is slight. Thus, the transparent mount base 103, the plastic-made lens array 101 and the original platen glass 105 are of close adhesion structure, and the relative position adjustment to arrange the plastic-made lens array to just middle of the object image is not required.
