Title: Writing device
Inventor: MISAO IKUO
IPC: G09G3/18
Filed: 1985-04-25
Abstract: PURPOSE:To make it unnecessary to use complex software and to shorten writing time by modulating laser light to interpolate it during a response period when the irradiating position of laser light is scanned at the writing of a straight line between discontinuous two points of a cell. CONSTITUTION:A liquid crystal display device consists of a liquid crystal cell 10, a writing means 20, a scanning means 30, a projecting means 50, a tablet 60, a microcomputer 70, etc. Even if address outputs Ax, Ay are changed at a time t0, the coordinates to be irradiated by laser light are not immediately turned to new coordinates, but are turned to the new coordinates after the passage of a response period t0-t1. During the period t0-t1, the coordinates to be irradiated by the laser light, are linearly changed from the old coordinates to the new coordinates. When a straight line is to be drawn between discontinuous two points (old and new coordinates), a writing pulse is supplied to a laser diode 23 during the response period t0-t1 of scanning of laser diode. Consequently, complex software is not required and the time can be shortened. In addition, a specific IC for graphics is not required.

Title: Flexible image fiber and its manufacture
Inventor: MATSUDA HIROO
IPC: G02B6/06
Filed: 1984-05-07
Abstract: PURPOSE:To manufacture an image fiber having flexibility in spite of its long size by forming parts where plural quartz-base linear image elements are united to one body by filling the space among the elements with soluble glass after dissolution and a part where the image elements are separated from each other by leaching out the glass. CONSTITUTION:A bundle formed by packing base materials for linear image elements into a quartz pipe is evacuated and heated to form a base material for an image fiber (IMF). This base material is heated and drawn, and the resulting drawn IMF is immediately coated with a primary coat (PMC) of a resin such as silicone or epoxy resin or a metal to increase the strength. The PMC17 and the quartz jacket 16 are removed by dissolution by a prescribed length corresponding to a part of the IMF requiring flexibility to expose the image element part 15, and the image elements are separated from each other by immersion in a solvent for glass. The part 15 is then cleaned and made smooth with a required lubricant or the like, and it may be covered with a plastic pipe or a metallic tube having superior flexibility. Thus, a long-sized flexible image fiber with a small optical loss can be obtd.

Title: Steam generating device
Inventor: KAMIMURA YUTAKA
IPC: F22B37/48
Filed: 1989-04-10
Abstract: PURPOSE:To prevent a water drain valve from being fixed by scale pieces caught between the ball and valve seat by providing a scale well in the water discharge pipe. CONSTITUTION:The scale component that is contained in water 19 adheres to the inner wall of a boiler body 2, but as soon as a steam generator is stopped, a water drain valve 12 opens and the water 19 in the boiler body 2 is drained. By the water draining, the boiler body 2 is rapidly cooled and contracts. At this time the scale 22 is peeled off by the difference of the thermal expansion coefficients of the boiler body 2 and the scale 22 to become scale pieces 22' and they fall down to the lower section of the boiler body 2 and are pushed out from a water supply port 4, and then fall down by their weight from a drain port 9. The scale pieces 22' that fall are stopped at scale wells 21a and 21b that are provided in the water drain pipe 21. The scale pieces 22' are, therefore, not accumulated on the surface of a ball 13 of the water drain valve 12 falling on it, and when the water drain valve 12 is opened, they are not caught between the ball 13 and valve seat 14.

Title: Rotation detecting apparatus for ball joint
Inventor: SASAE KEISUKE
IPC: G01B21/22
Filed: 1998-03-19
Abstract: PROBLEM TO BE SOLVED: To obtain a small rotation detecting apparatus by which the rotation around an output shaft of a ball joint can be detected simply by a method wherein the angle of rotation around the output shaft of the ball joint is computed by using the measured result of a longitude detector which computes the longitude of the magnetic pole position of a rotor on the basis of outputs of two magnetism detectors and by using the measured result of a shaft inclination detector which detects the inclination of the output shaft. SOLUTION: An optical position detecting element 11 fetches, as two-dimensional information, the center-of-gravity position of the distribution of irradiation light. A shaft inclination detector 21 computes the center-of-gravity position by using the measured output of the optical position detecting element 11 so as to be sent to an angle-of-rotation computing device 25 as a shaft-inclination measuring signal. Output signals V's of magnetism detectors 17, 19 which are installed inside a face parallel to the floor face inside a housing 3 are proportional to the cosine of the inclination of a magnetic pole N with reference to a straight line which connects the magnetism detectors 17, 19 to the center of a rotor.  As a result, when the outputs V's of the magnetism detectors 17, 19 are composed by a longitude measuring device 23, an angle which indicates the direction of the magnetic pole N projected onto a face which is formed of the magnetism detectors 17, 19 and of the center of the rotor can be found. Then, the angle of rotation around an output shaft 5 of a ball joint can be found by the angle-of-rotation detecting device 25 on the basis of the inclination of the output shaft 5 and on the basis of the longitude of the magnetic pole N.

Filed: 1996-04-12
Abstract: PROBLEM TO BE SOLVED: To confirm the characteristic deterioration of a surge absorber from its appearance by forming display on the surface of the outer resin of the surge absorber whose outer surface of the barrister element is coated with resin by using ink which irreversibly changed color. SOLUTION: An electrode 2 is formed on both major flat faces of a barrister element 1 whose major component is zinc oxide. Then, a solder plated copper lead wire 4 is connected by using eutectic point solder. Then the whole outer surface excluding the extraction part of the lead line 4 is coated with resin 5 and is heat cured. Then, display 7 which indicates product identification is marked on the surface of the resin 5. The ink used for forming the display 7 is the ink which irreversibly changes its color at a prescribed temperature. Thus, in the case where the barrister element in the surge absorber is abnormally heated to a temperature that the solder applied to solder the lead wire to the electrode face fuses, the character deterioration of the surge absorber can be confirmed from its appearance.

Title: Inkjet recording sheet

IPC: B41M5/00
Filed: 1984-05-09
Abstract: PURPOSE:To obtain an image with a clear ink dot by providing a coated film having polyvinyl alcohol mixed with an appropriate amount of a specified crosslinking agent to effectively inhibit the diffusion of ink dots attached to a film coated surface with a higher coated film strength while preventing ink running in the image. CONSTITUTION:A coated film which contains polyvinyl alcohol with the saponification rate of 50-90mol% and a copolymer of 2-4C olefine or stylene and maleic anhydride or an ammonium salt or a sodium salt thereof as crosslinking agent is provided on a film sheet. Unless the saponification rate meet the above- mentioned range, polyvinyl alcohol never allow a desired ink absorbability to be delivered due to the deterioration in the hydrophilic property. Any olefine used as crosslinking agent in which the number of carbon atoms is not in the above- mentioned range can not accomplish the fusion and fixation or glycols as one element of ink components as expected even when the polyvinyl alcohol is mixed with the copolymer produced using maleic anhydride. Thus, it is made impossible to promote dry fixation of ink leading to a greater attaching strength of ink after being dried.
