Title: Winding abnormality deciding method for electrical apparatus having winding
Inventor: SAKIMOTO TSUTOMU
IPC: G01R31/00
Filed: 1987-06-18
Abstract: PURPOSE:To simply decide a layer short circuit of a winding without disjointing an apparatus, by applying a prescribed voltage to a winding to be decided, and deciding the layer short circuit of the winding from a waveform shape of a current which is generated in the winding. CONSTITUTION:In case of deciding a coil 1, the coil 1 and a power source unit 5 are detached at coil terminal part J, K, and a test line 9 from a winding abnormality deciding device 6 is connected to the coil side terminals J, K. Thereafter, when a step signal is transmitted to the coil to be tested, from a signal generating part 7, a current flowing to the winding 1 becomes a waveform of time-lag of first order, when the winding 1 is not short-circuit. However, if a short circuit is generated in the winding 1, the same current as a current iS1 flowing to a coil 4 of the outside of the short circuit flows to a coil 3 of the short circuit part by an electromagnetic induction action. Therefore, between the coil 3 of the short circuit part and the coil 4 of the outside of the short circuit, M coupling is generated in the mutual induction action, a phenomenon in which the current flowing to the winding 1 rises stepwise appears, and a short circuit of a winding of an electric apparatus is decided by an abnormality deciding part 8.

Inventor: KAKIUCHI TETSUO
IPC: G01N29/04
Filed: 1979-11-27
Abstract: PURPOSE: To properly retain a position and direction of an inspection tool by a method wherein a moving quantity of vertical by moving shaft of a manipulator having at least two free inclining flexing shafts retained by a vertical moving shaft is taken out and this moving quantity is used to control the moving quantity of flexing shafts.

Title: High precision grinding apparatus for screw
Inventor: ONO YOSHIHIKO
IPC: B23G1/36
Filed: 1983-08-23
Abstract: PURPOSE:To attain uniform and efficient grinding of a screw, even of a one of very small pitch, by arranging a grinding tool to be held by a holder disposed above the screw member to be ground, which holder is capable of horizontal slight swinging, up-and-down movement, and rotation in both directions. CONSTITUTION:When a female screw is ground, a special purpose grinding wheel 95 in correspondence with the screw pitch of the thread portion 23a of the screw member 23 to be ground is inserted in a fixing hole 133 and fixed therein by set screws 135, while the screw member to be ground 23 is set on an work table 15. When the apparatus is put in operation, the grinding tool 95 makes eccentric turning, that is, slight swinging. While the grinding is made with abrasives supplied, the directions of the swinging are adapted to agree with the direction of the thread on he female thread portion 23a of the screw member to be ground 23 and the direction opposite thereto, so that the grinding tool 95 repeats slow up-and-down motion. If, then, a motor M is rotated in one direction and the other, the up-and-down motion is qucikened, and therefore, the working time is shortedned and the workability is improved. Since, further, the load exerting on the screw member 23 is allowed to escape by virtue of the horizontal movement of the table 15, the tool 95 is held free from damage, and thus, a screw even of small pitch can be satisfactorily ground.

IPC: B23K20/12
Filed: 1979-11-27
Abstract: PURPOSE: To make it possible to make friction pressure weldings to materials to be joined with a high recovery, by covering a polygonal material with Fe or an Fe alloy, when a polygonal material made of an alloy containing a single metal, such as Mo, W, Ta, Nb, etc., and Co, is joined to other metals by friction pressure welding.  
     CONSTITUTION: Joining component 1 having a polygonal cross-section and made of an alloy which is excellent in the heat resisting property, corrosion resisting property and wear proof and containing single metals of Mo, W, Ta and Nb or one element of them or Co is friction joined with material to be joined 2 composed of normal metals, such as soft steel, etc. In this case, the outer circumference of expensive joining material 1 is covered with covering material 3 composed of Fe material, such as soft steel, etc., or Fe alloy, and its joining surface 5 is friction joined with joining surface 6 of material 2 to be joined. Then covering material 3 is removed and joined material of joining material 1 and material to be joined 2 is manufactured. Since joining material 1 will never be oxidized because of its covering material 3, it will be very economical that expensive metallic materials can be used with a high recovery.

Title: Method and system for extracting voiced sound from speech signal and reproducing speech signal from extracted voiced sound
Inventor: SATO NOBUKI
IPC: G10L25/78
Filed: 1997-06-10
Abstract: PROBLEM TO BE SOLVED: To improve the quality of a reproduced speech signal by controlling a mixed amount of a speech signal received in the case of reproducing a speech and a 3rd signal at a receiver side corresponding to a voiced sound period, a hang-over period and a silence period so as to eliminate unnaturality of switching between the voiced part and the silence part to the utmost. SOLUTION: While voice/hang-over/silence identification 902 indicates a voiced sound, a voice sound level adjustment section 903 gives no loss to a voice digital signal 901 to improve the articulation but gives a large loss to an output of a 3rd signal level adjustment section 905 and mixes both the outputs. On the other hand, the section 903 controls the mixed amount so that the speech signal is smaller gradually and the 3rd signal is increased gradually up to a background noise level so as to smooth a change in a silence during the hand-over period. When the voice/hang-over/silence identification 902 indicates a silence, the section 903 sets the 3rd signal to the background noise level.

Title: Continuously variable hysteresis generating mechanism for clutch disc
Inventor: ASANO HIDEO
IPC: F16D13/64
Filed: 1994-07-05
Abstract: PURPOSE:To obtain a clutch disc hysteresis generating mechanism which possesses the continuous hysteresis characteristic for the transmission torque without adding parts. CONSTITUTION:During transmission, a clutch hub 1 and a spring holder 2 tend to generate the relative revolution vibration because of each torque variation absorbing function of springs 5-8. However, the spring constant KB of the spring 8 is set smaller than each spring constante KA of other springs 5-7, and a radial force F is generated between the clutch hub 1 and the spring holder 2, and a frictional force is generated by squeezing a friction ring 9 between both, and the relative rotary vibration between the clutch hub 1 and the spring holder 2 can be attenuated. Since the frictional force varies continuously according to the transmission torque. the hysteresis torque free from the excessiveness and shortage can be generated even with any transmission torque.
