Title: Minification of pixel data
Inventor: HIGUCHI OSAMU
IPC: B41J2/44
Filed: 1988-02-26
Abstract: PURPOSE:To perform minification processing which does not permit required pixels to be lost, using an extremely simple logic operation by extracting a string of pixels connected obliquely with pixels in a single line before or after (n) pieces of line and including the extracted pixels into the minification results. CONSTITUTION:If n equals 3, pixel data is subdivided into each three blocks in a row direction, and a spacer line L3 is left by thinning out lines L1, L2 of (m)th block. This processing enables the obtaining of a logic sum of all pixel data in lines (n)-1 from (mXn)th line to((m+1)Xn-2)th line as spacer lines of (m)th block. A logic product of the logic sum and the logic negative of pixel data in (mXn-1)th line before a single line of (m)th block is obtained in a row direction. These extracted pixels are independent points which are serially connected obliquely with pixels in a preceding line. In order to leave the extracted independent points P intact in the minified results without spacing, if a logic product of data in((m+1)Xn-1)th line, which is not thinned out and data of the independent point is sought, some minification results are obtained. The above procedures are to be taken in the sequential order of blocks m(1, 2, 3...) to obtain the whole minified image.

Title: Angular velocity sensor
Inventor: IIYAMA HIROSHI
IPC: G01C19/56
Filed: 1983-03-18
Abstract: PURPOSE:To eliminate an offset and to improve detection precision by providing a piezoelectric element on the surface perpendicular to the oscillation surface of an oscillator among flanks which support the oscillator. CONSTITUTION:When the piezoelectric elements 2a and 2b are supplied with an electric signal of frequency close to a resonance frequency, a tuning fork 4 starts oscillating. When this tuning force 4 is swiveled around an axis Z-Z, Coriolis force operates on a fitting part 5b having a surface perpendicular to the oscillation surfaces of the tuning fork 4, whose oscillations are transmitted to the fitting part 5b. At this time, the amplitude of oscillation transmitted to the fitting part 5b is proportional to an angular velocity around the axis Z-Z, so the electric signal generated between the piezoelectric elements 2c and 2d is proportional to an angular velocity around the axis Z-Z. The oscillation surfaces 4a of the tuning fork 4 are thin as compared with the area, so the oscillation mode in a direction X-X is much smaller than that in a direction Y-Y.

Title: Rotation control unit
Inventor: OOBA HARUTAROU
IPC: G05G5/04
Filed: 1978-04-17
Abstract: PURPOSE: To stop accurately at a desired position without giving shock to a rotation body by holding latch elasticly which shuts off power source at the same time with infixing into the recess of rotation body.  
     CONSTITUTION: Since the switch 33 of driving motor is closed at the same time with releasing latch 36 from the latch recess 31 when the electromagnet 40 is energized, the rotation body 30 is revolving in a counter-clockwise direction with the driving motor. Energizing time of electromagnet 40 is remarkably short, which is constrained by outer periphery of rotation body 30 to inhibit the reset of latch 36. When the rotation body 30 is rotated 180 degrees, the latch 36 is introduced into latch recess 32 by inertia force of spring 38 and simultaneously the switch 33 of driving motor is opened. The rotation body 30 is further revolving as extending the spring 38 by inertial force where pulling back by accumulated force of spring 38 after stopping rotation and stops by returning to the click point between return lock latch 41 and latch recess 31.

Filed: 1989-02-23
Abstract: PURPOSE:To prevent an antecedent coagulation due to lowering of the temperature of a molten metal in a slot part at the time of filling said part with a conductor material by blocking the slit part of a rotor core with a heating ring inner surface and yet by performing the preheating and heat insulation of said rotor core. CONSTITUTION:A molten conductor material 11 is poured into a basin part 4a and a rotor core 1 is pressurized by a lower die 3 and an upper die 9. When a pressurizing plunger 5 is raised in this state, the molten conductor material 11 goes through the gate 3b of the lower die, a tip end ring-forming part 3a and a core slot 1c, and reaches the rear end ring-forming part 9a of the upper die. In this case, the slit part 1d of a semienclosed slot is blocked by a heating ring 6 and a blocking plate 6a and a joint plate 6b so that the molten conductor material is prevented from jetting. Moreover, the rotor core 1 is preheated and heat-insulated by the heating ring 6, a melting temperature lowers little even when the molten conductor material passes through the slot 1c, and the antecedent coagulation of the molten conductor material in the slot 1c is prevented.

Title: Radiation quantity controller
Inventor: TANAKA TAKEO
IPC: B64G1/50
Filed: 1988-02-29
Abstract: PURPOSE:To make the number of components less and an assembly regulation easier and a price lower, by fitting a radiation control sheet made up of a shape memorizing alloy sheet and a bias spring sheet put together, and controlling the quantity of radiation by opening/closing a louver according to temperature. CONSTITUTION:When a heat transmission surface temperature rises up, a shape memorizing alloy temperature is warmed by heat which has moved to a heat transmission surface 18, a shape memorizing alloy bottom plate portion 4, and further to the whole of a shape memorizing alloy 1 through the transmission of heat, and is heightened. With this, force which is generated when a metal formation within the shape memorizing alloy 1 changes from martensite to austenite, is induced in a direction where a louver is opened. And as the shape memorizing alloy temperature becomes higher, force becomes greater than the force of a bias spring 2 and the louver is opened, and the quantity of radiation becomes larger as the area of heat transmission has come to have equivalently increased enough for the area of a louver portion 3. Whereupon, the heat transmission surface temperature comes down, and the louver is closed. Accordingly, radiation quantity control sheets automatically increase/decrease the quantity of radiation by means of such action of louvers as above and can regulate fixedly the heat transmission surface temperature.

Title: Low frequency therapeutic device
Inventor: JIKIBA YASUHIRO
IPC: A61N1/32
Filed: 1996-03-01
Abstract: PROBLEM TO BE SOLVED: To obtain a sufficient voltage even if the frequency of electric pulse stimulation is high, by equipping a plurality of coils and selecting a specific number of coils to be used by a second switching means to switch the output voltage of the step-up pulse. SOLUTION: A microcomputer 4 selects one or a several number from output terminals (a)-(d) according to a prescribed program by inputting a switch 2. For instance, the output terminal (b) is turned on/off upon inputting switch 2 for high power output switching means to turn a transistor 9 on/off. Thus, the current from a built-in battery 1 to a step-up coil 5 is intermittently flown to generate intermittent step-up pulses. The generated step-up pulses are stored in a capacitor 11 through a diode 10. At that time, the output terminal (a) is turned off. Inductance of the step-up coil 5 is made larger than that of a step-up coil 6. Thus, a higher output voltage is stored in the capacitor 11 with a same number of step-up pulse generation.
