Title: Motor
Inventor: MURAKAMI TOSHIAKI
IPC: H02K29/08
Filed: 1992-07-17
Abstract: PURPOSE:To obtain a motor which can be effectively controlled to be rotated by providing a magnetic shield for increasing a distance between a magnetic pilot and a stator core, and a magnetic sensor provided adjacent to the pilot. CONSTITUTION:A magnetic shield 20 is formed of a peripheral groove formed so as to increase a distance of edges between a magnetic pilot 17 and a stator 10. A motor is so operated that, when a winding 9 of the stator 10 is conducted, a magnetic flux is generated at a stationary core 8 to attract or repel a permanent magnet 16 of a rotor 14 to rotate it. Since the rotation of the rotor 14 is decided according to a positional relationship of poles between the stator 10 and the magnet 16, the position of the pole of the magnet 16 is detected by a magnetic sensor 19 to calculate a signal under control, the winding 9 of the stator 10 is conducted to continuously rotate the rotor 14. As a result, since the leakage magnetic flux from the stator 10 is remarkably reduced by a large reluctance of the shield 20, its rotation control can be effectively executed substantially without magnetic influence from the stator 10.

Title: Tip dressing device for welding tip and its method
Inventor: NAKAJIMA TOSHIHARU
IPC: B23K11/30
Filed: 1996-07-22
Abstract: PROBLEM TO BE SOLVED: To dispense with a complex controller for varying a pressurizing force stepwise by maintaining the revolution of a driving source with a delaying device for a specific time, after a stop command is received by the driving source for rotating a blade. SOLUTION: With a foot switch 45 stepped down, an electromagnetic valve 123 is actuated by a command signal for starting pressurization from a controller 128, so that a welding tip is applied to a blade by an air cylinder. It takes some time for the air cylinder to gain a prescribed pressure, with the notched quantity by the blade increasing gradually; therefore, no chipping occurs. Upon completion of machining and shaping, the foot switch 45 is released from the foot. With a command signal for stopping a motor M outputted to a relay 126, it is kept closed during the discharge of an electrolytic capacitor 127, a delaying device, so that the rotation of the blade is maintained for 60/N seconds or longer. As a result, burrs are removed which are generated during the machining and shaping.  Merely stepping down the foot switch 45 enables three steps of working consisting of pre-pressurizing, machining/shaping, and deburring.

IPC: H04N5/92
Filed: 1987-07-31
Abstract: PURPOSE:To reproduce a sound signal which does not make an unnaturalness feel between modes by making variable a low frequency characteristic in accordance with plural band limits. CONSTITUTION:At low pass filters LPF1-LPF3 inserted between a sound input terminal 1 and a time base compressing block 2 or between a sound output terminal 17 and a time base extending block, band pass filters BPF1-BPF3 are provided. For respective band pass filters BPF1-BPF3 in which the cut-off high frequency is higher, the cut-off low frequency is set lower. Thus, when the frequency characteristic is extended up to a high frequency, the band at the low frequency is widened and when the high frequency is suppressed, the low frequency is also suppressed in accordance with it. For this reason, the low frequency only is emphasized and without giving a hearing feeling which is harsh on the ears, a well-balanced sound signal can be outputted.

Title: Electronic device and mounting structure thereof
Inventor: TEZUKA SHINJI
IPC: H05K3/36
Filed: 1999-07-06
Abstract: PROBLEM TO BE SOLVED: To inexpensively and appropriately connect a warped or uneven subordinate substrate or mounting parts, such as electronic components, etc., to a mother board. SOLUTION: On an electronic component 1, the wetting areas between solder grains 4 and the electrodes of a subordinate board 3 are changed by opening electrode openings 8, having different sizes through a solder resist covering the surfaces of the electrodes 8, according to the then warping state of the board 3 immediately before the substrate 3 is connected to a mother board 2 through the solder grains 8. Namely, the openings 8 on the electrodes nearer to the mother board 2 are formed in larger sizes and the openings 8 farther from the substrate 2 are formed in smaller sizes.  When solder grains 4 having the same size are put on the openings 8 and solidified after the grains 4 are heated to a temperatures higher than their melting points, the wetting areas and heights of the solder grains 4 on the smaller openings 4 become narrower, and higher and the heights of the solder grains 4 on the larger openings 8 become lower. Therefore, the subordinate board 3 and mother board 2 can be connected appropriately and inexpensively to each other by absorbing the warping and unevenness of the board 3 by the heights of the solder grains 4.

Title: Emulsifying disperser
Inventor: NODA TSUNEHIRO
IPC: B01F27/73
Filed: 1986-08-19
Abstract: PURPOSE:To increase dispersing capacity by forming stair type step parts confronting each other in a shearing clearance between a rotor and a stator, and axially slanting the periphery of the step parts, and providing retention chambers consisting of teeth-shaped dent parts between steps. CONSTITUTION:A liquid to be dispersed is flowed along the inner surface of the stator S and introduced to a 1st retention chamber G1, where a radial flow J due to the rotation of the rotor R and an annular flow K along the peripheral surface of a half circle in the teeth-shaped dent part 9 are generated. The radial flow J is sheared by the radial shearing clearance Cr, and the liquid is emulsified and dispersed by pressure fluctuation due to the multiplied effect of the radial flow J in the chamber G1 and the annular flow K. Then the liquid is introduced to a 2nd retention chamber G2 by the rotation of the rotor R, and at the same time is sheared by the axial shearing clearance. The same emulsifying and dispersing actions as in the chamber G1 are carried out in the chambers G2 and G3. Thus, by plural shearing actions and pressure fluctuations, an emulsifying and dispersing operation is effectively carried out.
