Title: Pattern recognizing method
Inventor: OZAKI TAKAYUKI
IPC: G06F17/15
Filed: 1983-05-02
Abstract: PURPOSE:To recognize patterns at a high speed by omitting operations for elements around the element at a certain point if the value of this element is smaller than a prescribed value when each element of a matching degree matrix is operated. CONSTITUTION:In case of generation of a matching degree matrix M, if the value of an element f(i-1, j-2) [namely, a degree of correlation of a point (i-1, j-2) to a standard picture] is larger than a prescribed threshold T when the element f(i-1, j-2) is operated, an element f(i, j-2) at the adjacent point which is not calculated is operated. If said value is smaller than the threshold T, the degree of correlation of the element at the adjacent point is not calculated, and a degree of correlation f(i+1, j-2) at a point lower then the point (i-1, j-2) by, for example, one column is operated and obtained. Meanwhile, a maximum degree of correlation in a region is stored in the process where a prescribed number of degrees of correlation in this region is obtained, and succeeding calculations are omitted with respect to this region if this maximum degree of correlation is sufficiently larger than the threshold T.

Title: Numerical control device with measurement function
Inventor: KAWADA SHOJI
IPC: B23Q17/20
Filed: 1990-03-26
Abstract: PURPOSE:To make a measurement with high accuracy by determining the angle of a main shaft turning-direction indexing so that the contact part of an appropriate touch probe can be always the same point corresponding to the shift direction of the control shaft of the touch probe, and positioning the main shaft beforehand. CONSTITUTION:A main control part 1 outputs the angle command of a main- shaft turning-direction indexing (to be called main-shaft indexing hereafter) to a main-shaft indexing control 2, which output is based on a control shaft shifting direction when a touch probe is brought in contact with a measurement piece. The main-shaft indexing control 2, on receiving the command, gives a main-shaft indexing command to a main-shaft driving part 3, which acts based on a main-shaft motor indexing. A shaft control process part 4, to which a tough signal is input, immediately memories the control shaft position at this time as a latch position, and at the same time, send the information to the main control part, stopping the control shaft shift. The main control part 1 recognizes the latch position to be a contact position of the touch probe and finishes measuring one direction.

Title: Thickness-shear piezoelectric vibrator
Inventor: TAKATSUCHI HEIJI
IPC: H03H9/19
Filed: 1986-04-04
Abstract: PURPOSE:To deteriorate the Q value of the n-th higher harmonic vibration without deteriorating the vibration sharpness Q of the basic wave vibration, by forming an electrode thin film part at the center of an exciting electrode film formed on a piezoelectric element plate. CONSTITUTION:The electrode films 12 and 13 for excitation of piezoelectric element plate are formed in desired forms on both sides of a thickness-shear piezoelectric element plate 11. Then an electrode thin film part 14 is formed at the center of the film 12 within an area of <=1/2 the film 12. The energy enclosing distribution of a thickness-shear piezoelectric vibrator is concentrated at the center of the electrode film as the degree of higher harmonic vibrations is increased. Thus it is possible to change the balance of the frequency reduction value caused by the mass addition effect. Then the frequency difference can be increased between the basic wave vibration and the n-th higher harmonic vibration.

Title: Control device for automatic transmission
Inventor: YAMAMOTO KOICHI
IPC: F16H61/02
Filed: 1986-04-03
Abstract: PURPOSE:To reduce the shock of speed change, by selecting 1st low speed step for a determined time before changing over to 2nd low speed, which causes engine brake, in slow running state when an engine brake is actuated. CONSTITUTION:When a speed change gear mechanism 10 is switched from a high speed to a low speed for engine brake, if the car speed is judged to be lower than a standard speed by the signal from a number of revolution detecting part 200a, solenoid valves 110b-130b are switched off together by the signal from the slow speed detecting part 200b of a control means 200, and 1st slow speed step which does not cause engine brake is selected for a determined time. And after that, only said solenoid valve 130b is switched on to select 2nd low speed step which causes engine brake. Thus, speed changing is carried out smoothly for preventing speed change shock from occurring. When the car is running in a high speed cruising state, however, the switching over is made directly to 2nd low speed step to avoid sudden change of the rate of speed reduction.

IPC: G01N33/20
Filed: 1989-03-29
Abstract: PURPOSE:To estimate an evaporation residue efficiently by arranging an inner cylinder holding a volatilizing refined material while an evaporation thereof is repeated being placed in a cylinder. CONSTITUTION:An evaporation dish with a specified weight of selenium material Se measured is inserted into a distillation inner cylinder at an electric furnace 1. A cooling water flows through a cooling jacket 3 and a vacuum pump 15 is operated to bleed air within a distillation cylinder 2 through a vacuum hose 14, purifying bottles 13 and 11 and a vacuum hose 10. Under such a condition, when the furnace 1 is heated, the material Se is evaporated to flow to the other end side and the material evaporated is cooled on an internal surface of a cylinder 2 cooled with the jacket 3 to solidify and accumulated in a tank 5. The material passing the cylinder 2 is caught with a glass wool 16 when passing through the purifying bottles 11 and 13 so as not to be released to the outside air. Moreover, upon the completion of the evaporation, the distillation inner cylinder is taken out of the cylinder 2 and the weight of an evaporation residue in a magnetic evaporation dish is measured. Thus, a ratio of the evaporation residue is estimated as impurities contained in the material Se.

Abstract: PURPOSE:To set an objective lens within a focus pull-in range in a short time by setting the initial position of the objective lens in the vicinity of the external part of the focus pull-in range, thereafter, moving the objective lens, and executing the position setting. CONSTITUTION:Since the initial position set range of an objective lens 17 can be enlarged several-ten-fold that of a focus pull-in range (approximately 40mum) by making the initial set position of the objective lens 17 into the vicinity of the external part of the focus pull-in range, for example, the range of approximately 2.0mm at an upper side, the initial position setting of the lens 17 can be easily executed. Next, by moving the lens 17 can toward the focus pull-in range and position-setting it within the focus pull-in range, the lens 17 can be led in a focus position based on a focus error signal. Thus, the objective lens can be position-set within the focus pull-in range in a short time, and a work to apply a focus to the objective lens for each object can be shortened.

Filed: 1980-06-11
Abstract: PURPOSE: To simplify a running mechanism and a steering mechanism, by providing four wheels so that two wheels on one diagonal act as steering and driving wheels and the other two wheels act as driven wheels which can be optionally turned for 360°.  
     CONSTITUTION: Two wheels 6 on one diagonal are used as driving wheels which can be rotated forward and backward. The driving wheels 6 can also act as steering wheels. The wheels 6 are steered and controlled through a transmission mechanism 10 including a rod 8 and bevel gears 9 as main constituents, by a steering power source 7 made of a motor installed on the central part of a base plate 2. Wheels 1 on another diagonal are driven wheels 13, each of which is turned as a whole for 360° relative to a portion 12 for mounting a support frame 11 on the base plate 2. The forward and backward rotation of the motor 7 is transmitted to a steering shaft 14 through the transmission mechanism 10 and gears 19, 16 to move the wheels forward and backward. Since the position of contact between the wheel 1 and a floor 25 is not coincident with the center of gyration of the shaft 14, the wheel 1 is rotated as a whole on the floor 25 so that only rolling friction is caused between them. Therefore, the wheel 1 can be moved by a small force.
