Title: Timing gear cutting method
Inventor: TAKEDA TOSHIO
IPC: F16H55/17
Filed: 1984-09-13
Abstract: PURPOSE:To improve a degree of relational accuracy between a keyway and a gear tooth ever so better, by performing gear cutting at the specified angle, while making the gear-cut tooth accord with a concentric and equal phasic state, and machining rotation, lockup and engagement elements with the equal phase. CONSTITUTION:In case of gears 10 and 10' being locked with keys 13 and 13', each timing angle alpha of rotors 16 and 16' and these keys 13 and 13' is expressed with an equation of alpha=180(2n-1)/Z (provided that alpha is of an angle between both engaging elements in time of use for gear assembling, Z is a tooth number and n is an optional positive integer), under which gear cutting takes place, and the next gear-cut tooth is made to accord with a concentric and equal phasic state whereby rotation, lockup and engaging elements are machined with the equal phase. Therefore, a keyway gets off with only one whereby machining is every so easy and, what is more, timing accuracy between each of gears comes high.

Title: Data updating system for display memory
Inventor: YASUMURO TAKETOSHI
IPC: G09G1/02
Filed: 1987-08-03
Abstract: PURPOSE: To prevent flickering of display in a display screen especially in the case that the speed at which data is written in a display memory is higher than the period of one-frame raster scanning by displaying rewritten display data at least once. CONSTITUTION: A latch circuit 11 holds a plotting address, that a plotting processor 6 sends to a bit map memory 9, and holds the last plotting address of a series of display data rewritten by the plotting processor 6. A comparison circuit 12 compares the address held in the latch circuit 11 with a display address for read of display data, which is sent from a CRT control circuit 7, and sends a coincidence signal in the case of coincidence. A counter 13 counts the signal sent from the comparison circuit 12, and when the counted number reaches a prescribed value, the counter sends a signal to the plotting processor 6 so that it will start the write processing of a series of next display data. Consequently, rewritten blocks are certainly displayed even if the plotting speed at which display blocks are expanded in the display memory is high. Thus, flickering of the picture is prevented.

Title: Liquid crystal display element
Inventor: HASHIMOTO KENJI
IPC: G02F1/133
Filed: 1986-08-21
Abstract: PURPOSE:To make a full-color display by combining three kinds of pigments which differ in absorption wavelength range and three kinds of liquid crystal which differ in crossover frequency and threshold voltage. CONSTITUTION:The three kinds of pigments which differ in absorption wavelength range use a magenta pigment, a cyan pigment, and a yellow pigment in concrete. Those three kinds of liquid crystal have mutual different crossover frequencies and threshold voltages, which is utilized. Black is therefore represented by the absorption of the three kinds of pigments when no voltage is impressed, and the impression of a specific voltage changes the liquid crystal molecule array in a specific microcapsule corresponding to it to eliminate the absorption of the pigment contained in the microcapsule, thereby making a color change. Consequently, a crossover frequency and a threshold voltage are selected to make the absorption of the corresponding pigments different, thereby making the full-color display.

Title: Master disk for v-groove optical disk
Inventor: NANBU TARO
IPC: G11B7/24047
Filed: 1988-08-03
Abstract: PURPOSE:To allow a surface worked with V grooves to act also as a sputtering blocking layer without generating roughness on the surface and to allow stable production accordingly by exposing metal components which are hardly oxidized and have the sputtering rate lower than the sputtering rate of Ni on the above- mentioned surface. CONSTITUTION:A film 2 contg. at least one among B, C, Al, Si, Ti, V, Cr, Ce, Zr, Nb, Mo, Ru, Hf, Ta, W, Re, Os, and Ir is formed on the master disk for the optical disk previously worked with the V grooves for tracking. At least the surface to be cut with the V grooves is formed of a material 3 essentially consisting of Al. The metal components which are hardly oxidized and have the sputtering rate lower than the sputtering rate of the Ni are exposed on the surface worked with the V grooves and, therefore, the roughening by oxidation does not arise on the surface even if the bases of the bits formed by sputtering are exposed to the atm. air. In addition, said bases can act as the sputtering blocking layer at the time of dry etching.

Title: Ice making machine
Inventor: MEGATA MASAHITO
IPC: F25C5/10
Filed: 1996-07-24
Abstract: PROBLEM TO BE SOLVED: To make beautiful plate shaped ice having a set thickness by heating each part without use of a heat transfer device such as a heater by heating circulated water supplied to a tank using as a heat source hot gas effluent from an outlet pipe of a discharge pipe of a compressor or an outlet pipe of a condenser. SOLUTION: Once ice making operation of an ice making machine is started by supplying water into a chamber tank 13, outlet temperature of a condenser is raised, and a sprinkler 12 is heated with a condenser outlet pipe 25. The condenser outlet pipe 25 passing through the sprinkler 12 is further directed to an upper part of the tank 13 to raise atmospheric temperature of the upper part of the tank 13 and hence prevent a float 22 from being frozen. Thereafter, the condenser outlet pipe 25 is communicated to the interior of the tank 13, whereby there is heated the circulated water cooled while circulating the upper portion of the evaporator 11 with the aid of a pump motor 14. Thus, the circulated water is prevented from being steeply lowered in its temperature for prevention of freezing.  The condenser outlet pipe 25 is directed to the evaporator 11 through a capillary tube 27 from a drier 26 to form a freezing cycle.

Abstract: PURPOSE:To positively make connection in a simple manner by monolithically forming a ring section onto one conductive wire member, monolithically forming a projected section onto the other conductive wire mamber, and engaging the projected section with the ring section. CONSTITUTION:A part of a conductive wire member 1 is curled into a ring form by one turn, and the conductive wire member 1 is pulled out while a jig 4 is put into said curled section 2 so that the curled section 2 is thereby contracted in diameter into the shape of the jig 4. Furthermore, the curled section 2 is twisted so that a ring section 5 is formed. Or the section is pressed so as to be molded into an integrated ring section shape 6. ln this place, the hole 7 or 8 of the ring section 5 or 6 is formed identical in diameter to the jig 4. The part of the conductive wire member 9 is bent and folded so that the sides of an angle 10 are formed so as to be over-lapped, and the over-lapped section 11 is pressed in order to be molded into one body so that a projected section 12 is formed. Then, the projected section 12 is inserted into the hole 8 of the ring section 6, and the tip end 12a is squeezed by a press so as to be fixedly connected. This constitution prevents the connection from being affected by heat, and also has complete freedom from defective welding, thereby enhancing the reliability of electrical connection.

Title: Continuously variable transmission
Inventor: TAKAMIYA KIKUZO
IPC: F16H37/02
Filed: 1987-08-05
Abstract: PURPOSE:To improve the efficiency of transmission by pressing a driven frictional wheel against a driving frictional ring by the action of a cylindrical end face cam rotated together with a driven rotor to give a thrust to a movable driven rotor. CONSTITUTION:A driving frictional ring 39 fitted on a driving frictional wheel 38 through a spline is constituted to be pinched by driven frictional wheels 54, 56 provided respectively on a driven rotor 48 and a movable driven motor 57. When a slip takes place between the driven frictional wheels 54, 56 and the driven frictional ring 39, a rotary phase difference takes place between the driven rotor 48 and the movable driven rotor 57. As a result, the driven frictional wheels 54, 56 are pressed against the driving frictional ring 39 by the action of cylindrical end face cams 65, 72 harder than they are previously pressed. That is, these cylindrical end face cams 65, 72 act as a toggle joint to increase a contact force of frictional wheels if any slip takes place between the frictional wheels. Thus, the slip along with the increase of a load is remarkably reduced to improve the efficiency of transmission.

Filed: 1989-07-27
Abstract: PURPOSE:To control the electric discharge of an electric power source by eliminating the purposeless operation of a step motor by suspending the operation for a step motor or cutting off the electric conduction when the voltage value of the electric power source for the step motor drastically lowers. CONSTITUTION:The electric current supplied from a battery 7 which is chopping- processed by the chopping transistors 106 and 110 which are PWM-controlled in the driving timing of the transistors 101-104 for drive which are controlled by a CPU 105 is supplied into each phase coil of a step motor 52 which drives a throttle valve in the closing direction independently of the accelerator operation, and drive is performed. In this case, the cpu 105 monitors the voltage value of the battery 107, and when the voltage value lowers to the value with which the operation torque can not be obtained, selection of the driving phase by the transistors 101-104 for drive is not carried out, and operation is suspended, and a waiting state is generated, while if the voltage value lowers to the value with which the holding torque can not be obtained, the electric conduction of the step motor 52 is cut off. Thus, the electric discharge of the battery can be suppressed.
