Title: Thermal write type liquid crystal display device
Inventor: SAITOU AKIRA
IPC: C09K19/06
Filed: 1984-03-09
Abstract: PURPOSE:To keep a write speed constant by equalizing a working speed by heating up to a normal temperature, when a temperature of a liquid crystal panel is below a normal temperature, and shortening a pulse voltage without executing a temperature control, in case a temperature of the panel is higher than a normal temperature. CONSTITUTION:A voltage comparator 20 generates a prescribed voltage, when an input voltage from a resistance.voltage converting circuit 19 is lower than the voltage of a reference power source 21. Only a heating electrode driving circuit 6 is operated, and with respect to electrodes consisting of (n) pieces, the electrode is selected successively one by one and a heating electrode 4 is heated once each, and thereafter, this operation is repeated until a signal input from the voltage comparator 20 is gone. When a temperature of a panel 10 exceeds a set value, a voltage output time of a shift register 26 is controlled in accordance with a voltage value corresponding to the temperature of the liquid crystal display panel 10 outputted from the resistance.voltage converting circuit 19, and an applied time of a heating pulse voltage outputted from a switching circuit 27 is controlled. In such a way, even if a temperature of the liquid crystal display panel is varied, a write working speed can be set to a prescribed speed or above.

Title: Die for extrusion molding of thermoplastic resin and molding of polyester film using the same
Inventor: KIYOHARA KAZUTO
IPC: B29C48/305
Filed: 1996-02-05
Abstract: PROBLEM TO BE SOLVED: To mold a polyester film free from a die line by subjecting only the lip on an anti-taking-over side among a pair of die lips to R processing or corner cut processing. SOLUTION: A die and die lips are formed so as to have a structure such that an R processing part 3 of 0.1-5.0mm, pref., 0.5-2mm or corner cut processing part is provided to the leading end of the die lip only on an anti-gaking-over side 32 among the die lips. R processing is an abridgment of round processing and the leading end of each die lip usually finished at a right angle is rounded to be formed into a circular arc shape. By this constitution, an extruded resin film is pulled rearwardly along the lip 32 on the anti-taking-over side to go away from the lip 31 on a taking-over side and, therefore, deteriorated matter becomes hard to adhere and the adhesion and growth of discharges are suppressed and no die line is generated.

IPC: F16C3/03
Filed: 1997-02-27
Abstract: PROBLEM TO BE SOLVED: To provide a high strength spline to reduce a cost and be durable against a repeat stress and to provide manufacture thereof. SOLUTION: By forming an arcuate spline 1 consisting of an approximate arcuate continuous curve in which a part except a tip 3A is formed, concentration of a stress occurring in a bottom 3B is prevented from occurring and a metallographic structure in the vicinity of a surface is formed along a surface shape. Further, by applying surface solidifying treatment, the strength if a tooth 3 part is increased and a fatigue strength is modified. Further, since a compression residual stress is applied in the vicinity of a surface, a tensile stress is reduced. Diffusion treatment, such as surface quenching treatment and softening treatment, is applied to a part ranging from at least the tip 3A of the arcuate spline 1 to the bottom 3B thereof, and a surface is solidified. After surface quenching and diffusion treatment, shot peening treatment is effected.

Filed: 1980-04-07
Abstract: PURPOSE:To prevent staining of a wire with dust, assure uniform discharge over a  long period of time and make constitution simple by electrically capturing and removing the dusts in the air around the apparatus and flowing dust-free air into a  corona discharging wire part. CONSTITUTION:Insulator shields 141, 142 are disposed on both right and left of a corona discharging wire 13 in its longitudinal direction with said wire in-between, and the upper and lower sides of the wire 13 are opened as openings. Conductive members 16 which permits the inflow of air between the shields 141, 142 are disposed on  one opening part. Corona current mostly flows toward a photoreceptor surface 1, and the spacing between the wire 13 and the member 16 is a negative pressure state. The outside air flows into between the shields 141, 142 by passing the openings between the respective members 16 from the upper opening. At this time, the dusts in the air are sucked and captured on and by the members 16 by the voltage generated in the members 16, and the air containing no dusts is flowed into between the shields.

Title: Document binding tool
Inventor: MORI CHUZO
IPC: B42F13/06
Filed: 1997-02-28
Abstract: PROBLEM TO BE SOLVED: To sufficiently perform a double-page spread by preventing bound documents from coming apart even when hooking between both ends of a binding belt and a press plate is released. SOLUTION: The interval between two holes 901 with a large diameter provided on a press plate 7 is narrower than the interval between two holes opened on documents and the terminal ends of slits 902 are approximately the same as the interval between two holes opened on documents. In addition, the diameter of the hole 901 with a large diameter is made larger than the diameter of the head part 801 and the width of the slit 902 is made smaller than the diameter of the head part 801. As the result, there exists no possibility of slipping out of a binding belt 8 inserted through the hole 901 with a large diameter from the press plate as the head part 801 is moved to the slit 902 side by restoring force of the binding belt and the head part 801 is caught in the slit 902. It is possible thereby to sufficiently perform a double-page spread by prevent bound documents from coming apart.
