Title: Ultrasonic probe
Inventor: UDAGAWA YOSHIO
IPC: G01B17/00
Filed: 1995-05-19
Abstract: PURPOSE: To ensure focal depth while enhancing inspection efficiency by providing a vibrator having a recessed curved surface toward the emitting direction of ultrasonic waves and the solid delay arranged in front of the vibrator and forming the transmission medium of ultrasonic waves in a probe. CONSTITUTION: A vibrator 1 receives vibration voltage to be vibrated to generate ultrasonic waves. The vibrator 1 has a focus of ultrasonic waves at an extremely short distance to converge ultrasonic waves to the focus or the state near to the focus within an ultrasonic probe 100. A delay 2 protects the probe 100 and has sufficient width (d) in the emitting direction (z) of ultrasonic waves and, by the vibrator 1, ultrasonic waves are converged to the focus or the state near to the focus within the delay 2. A damper 3 absorbs unnecessary ultrasonic waves reflected within the probe 100. Herein, by forming the leading end surface 20 of the delay 2 into the surface shape of a material to be inspected, the attenuation generated in a gap (g) can be reduced.

Title: Controller of induction motor
Inventor: TODA SHINICHI
IPC: H02P23/08
Filed: 1994-06-28
Abstract: PURPOSE:To materialize highly accurate vector control by estimating the secondary resistance value of an induction motor by slip frequency control, and performing vector control, using this estimated secondary resistance value. CONSTITUTION:The proportional differentiation controller 72 of a secondary resistance estimator 7 operates a secondary resistance value R2 so that slip frequency estimate wSS and slip frequency wS may conform to each other. Thereupon, it follows that the secondary estimate R2S and the actual secondary resistance conform to each other. It follows that this operation is performed always while a slip frequency controller is controlling a VVVF inverter, and the secondary resistance, which changes by temperature rise, etc., can be estimated. When the rotational frequency reaches the specified value or under, the slip frequency control is changed over to the vector control, and when the vector controller controls the VVVF inverter, the vector control is performed, using the secondary resistance estimate R2S right before the changeover. Hereby, highly accurate vector control can be materialized.

Title: Bar-code reader
Inventor: YOMOGIDA MATSUO
IPC: G06K7/10
Filed: 1987-06-13
Abstract: PURPOSE:To eliminate the influence of a noise, and to generate correct information of a bar-code by adjusting suitably a level of a comparing signal in accordance with a state of the bar-code. CONSTITUTION:When a peak value D1 of a signal A is held, and an original signal B exceeds this peak value, an output of a comparing part is switched from low to high. Also, when a peak value D2 of a signal C is held, and a level of the original signal B becomes lower than this peak value, the output of the comparing part is switched from high to low. By a state of a bar-code, for instance, in case when contamination exists in a space part and a reflection factor is varied, a value of resistances R3, R4 is adjusted so as to take large a level difference between the original signal B and the comparing signal C, and also, in case when that which has been printed by a dot printer, or a blur in a bar part exists and the reflection factor is varied, a value of resistance R1, R2 is adjusted so as to take large a level difference between the original signal B and a comparing signal A. In such a way, the influence by a noise can be eliminated to the utmost.

Abstract: PURPOSE:To avoid a discrepancy between a determined origin and a real center of turning by a method wherein coordinate values are obtained by calculating the center point between a predetermined target point on a pellet and a target point in the state after the pellet is turned 180 degrees and the center position of turning is corrected and determined with the obtained coordinate values. CONSTITUTION:First, the coordinate values (X1, Y1) of a predetermined point in a pattern 21a on a pellet 8 are read by a controller 12 under the condition that a registered pattern 21 and the pattern 21a coincide with each other while a product 2 is placed on a bonding stage 3. Then the bonding stage 3 is turned 180 degrees and, based upon the registered pattern 21 again, the pattern 21a on the pellet 8 which coincides with the registered pattern 21 is referred. Thus, under the condition that the registered pattern 21 and the pattern 21a on the pellet 8 coincide with each other, the coordinate values (X2, Y2) of a predetermined point are read by the controller 12. The controller 12 calculates the center point between the two points based upon the two sets of the coordinate values and the calculated point is determined as an origin.
