Title: Method and device for visualizing internal stress and internal inclusion of opaque flat plate
Inventor: ONO JUNZO
IPC: G01L1/00
Filed: 1989-12-13
Abstract: PURPOSE:To easily visualize the internal stresses or inclusions of discrete materials by transmitting ultrasonic waves in a specimen, receiving the transmitted ultrasonic waves in a 1st polarizing plate, transmitting monochromatic circularly polarized light through this 1st polarizing plate and allowing the polarized light transmitted therethrough to transmit through a 2nd polarizing plate, the main axis of which intersects orthogonally with the main axis of the 1st polarizing plate. CONSTITUTION:The ultrasonic waves which are projected from an ultrasonic oscillator 4 to the specimen 1 and are transmitted therethrough are cast onto the 1st polarizing plate 2. The polarizing plate 2 is irradiated with the circularly polarized light with sodium of a prescribed wavelength as a light source 5 and the transmitted light is received in the 2nd polarizing plate 3. The main axes of the polarizing plate 2 and the polarizing plate 3 are so disposed as to intersect orthogonally with each other. Bright and dark stripe patterns appear and the stress distribution of the specimen 1 is visualized when the prescribed tensile stress is applied to the specimen 1 in parallel with the surface. Namely, the isochromatic lines of the internal stresses are so visualized as to draw arcs on the object from the center in the direction of the applied stress. For example, a crack is expressed as a disturbance in the isochromatic lines.

Title: Running controller of electric vehicle
Inventor: ISHIDA YOSHINOBU
IPC: B60L15/20
Filed: 1998-11-13
Abstract: PROBLEM TO BE SOLVED: To reduce an operating force and prevent unstable operating force by generating in a motor a driving force which is increased considering amount of change preset based on a difference between the operation force and threshold value upon determination that the operating force has exceeded a threshold value. SOLUTION: When an operating force is increasing even if an operating force detecting signal Fin is less than a threshold value Fsl, it means that a running load is increasing. In this case, if amount of change dFa becomes a negative and a drive force is reduced, an operation force is increased to a large extent as the reaction and the operation force becomes unstable. Therefore, the operation force is stabilized by setting amount of change dFa to zero to maintain the preceding value. During increase of operation force, when the operation force detecting signal Fin becomes larger than the threshold value Fsl even if it does not reach the setting value Fs, a positive amount of change dFa is given to quickly raise the drive force to prevent that the operation force becomes large unnecessarily.

IPC: B65H67/052
Filed: 1987-12-23
Abstract: PURPOSE:To catch and wind linear material reliably even under high speed by arranging a phase-match clutch between the rotary drive system of a guide disc and a cam. CONSTITUTION:An operation lever 22a is projected to the side of a bobbin 6a and rotated so as to project a catch pawl 20a to the side of the bobbin 6a. Since a push board 24a comes quickly to a regular approach position, the catch pawl 20a is fully projected under a condition where the engaging section of the operation lever 22a is landed on a flat section 31a. In such a manner, the push board 24a is pushed out reliably by means of a phase-match rotary clutch 51a in synchronization with the bobbin 6a and a guide disc 3a and subsequently it is retracted, then a catching device 18a catches an optical fiber reliably then retracts. When the guide disc 3a and the bobbin 6a rotate furthermore, the optical fiber is torn off and winding of the optical fiber around the bobbin 6a is started.

Title: Printed wiring board
Inventor: MIYASAKA KATSUMI
IPC: H05K1/11
Filed: 1996-12-04
Abstract: PROBLEM TO BE SOLVED: To provide a printed wiring board with which both the suppression of the power loss in feeding patterns and the improvement of the efficiency of the soldering on lands can be realized. SOLUTION: A printed wiring board 1 is a motor board. Lands 31, 41 and 51 to which the coil ends, etc., of a motor are soldered are electrically connected to wide feeding patterns 3, 4 and 5 with linking parts 33, 43 and 53, which consist of a plurality of narrow surface patterns. Therefore, even if the widths of the feeding patterns 3, 4 and 5 are widened in order to suppress the power loss caused by the resistances of the feeding patterns 3, 4 and 5, heat does not leak toward the feeding patterns 3, 4 and 5 at the time of soldering on the lands 31, 41 and 51. As solder layers are also formed on the surfaces of the linking parts 33, 43 and 53 at the time of soldering, the power loss in the linking parts is very little.

Title: Origin restoration method of numeral controller
Inventor: TAKEKOSHI MICHIO
IPC: G05D3/00
Filed: 1989-12-15
Abstract: PURPOSE:To improve positioning accuracy by stopping a main spindle after detecting a Z phase, moving the main spindle at an approach speed until a pulse change in an A or B phase is detected, finding out a inertia traveling distance obtained after detecting the Z phase, finding out the residual distance based upon the inertia traveling distance, and then positining a work based upon the residual distance. CONSTITUTION:After detecting the Z phase, the main spindle is temporarily stopped and then moved at the approach speed and the interia traveling distance is calculated by an inertia traveling distance calculating means 40 based upon the change pulse of the A or B phase. Then the residual distance up to a positioning position (specifying a prescribed position such as the succeeding Z phase) is calculated by a residual distance calculating means 41 based upon the inertia traveling distance and the number of pulses obtained by a main spindle encoder(ENC) 34. Finally, a speed pattern 4 is found out by the positioning operation of a positioning calculating means 42 based upon the residual distance and the speed of the main spindle 32 is rapidly positioned based upon the speed pattern 4. Consequently, the positioning accuracy can be improved without fixing a dog to the main spindle side.

Title: Spark killer circuit of switching element
Inventor: IIDA MASAKAZU
IPC: H02M7/155
Filed: 1999-11-16
Abstract: PROBLEM TO BE SOLVED: To provide a spark killer circuit capable of positive killing arc-sparks across a switching element even if a constant voltage element such as a diode is connected with a shorting circuit of the switching element. SOLUTION: This spark killer circuit of the switching element is connected in parallel with a shorting circuit 9 short circuiting across a thyristor 2, including a diode 8. The thyristor 2 is connected in series with an inductance element 3. In this spark killer circuit, when the shorting circuit 9 is short-circuited by tuning on a switch 10 for extinguishing the spark of the thyristor 2, the diode 8 causes forward voltage Vf and the inductance element 3 causes counter- electromotive voltage Vl. This counter-electromotive voltage Vl offsets the forward voltage Vf caused by the diode 8, thereby making the forward voltage applied to the thrysitor 2 to less than barrier layer voltage Vse.
