Title: Purging of fuel
Inventor: UCHIYAMA YOSHIHIRO
IPC: F23N5/24
Filed: 1983-07-08
Abstract: PURPOSE:To reduce the amount of consumption of nitrogen gas by a method wherein the fuel, remaining in a fuel feeding pipe, is purged by remaining steam in a steam generator. CONSTITUTION:A steam pipe 11, sending steam from the heat transfer tube 10 of a waste heat boiler 7 to the immediately downstream of a fuel regulating valve 3 of the fuel sending pipe 9, and a steam stop valve 12 are provided in the system. The steam stop valve 12 is being closed during a normal operation and the steam is being flowed in the steam pipe 11. In such a device, when the operation is stopped, the fuel regulating valve 3 is closed but the fuel remains in the fuel sending pipe 9. Therefore, the steam stop valve 12 is opened immediately after the fuel regulating valve 3 is closed and combustion is stopped to send a part of the steam remaining in the waste heat boiler 7 into the fuel sending pipe 9 and discharge the fuel in the pipe 9 into a burner 4. When the necessary amount of steam to send the fuel is sent into the fuel sending pipe 9 and the purge of the fuel is finished, the steam stop valve 12 is closed and, thus, the purging is finished.

Title: Manufacture of sintered permanent magnet
Inventor: ISHIBASHI TOSHIYUKI
IPC: H01F1/08
Filed: 1985-06-06
Abstract: PURPOSE:To realize particle-formation of magnetic powder without its magnetic characteristics being deteriorated, by performing particle-formation by the use of tetrachlorodifluoroethane serving as binder. CONSTITUTION:Particle-formation is performed by the use of tetra chlorodifluoroethane serving as binder. Since tetrachlorodifluoroethane has a boiling point at 92.8 deg.C and freezing point at 26 deg.C, it freezes at the temperature below room temperature. Since it has a viscosity of 0.42 centipoise and surface tension of 23dyne/cm at the temperature of 30 deg.C, it is easily mixed with mag netic powder by being heated at 30 deg.C or more, and the particle-formation of the magnetic powder can be performed by decreasing the temperature during this particle-formation. Hence, improvement in mass-productivity, decrease in cost, and stabilization in quality can be realized.

Title: Vector control unit of ac motor
Inventor: KUSUMOTO SATOSHI
IPC: H02P21/00
Filed: 1986-05-30
Abstract: PURPOSE:To make it possible to detect the flux stable and highly precise in the overall speed range of a motor without being affected by the offset voltage and temperature drift, by finding the flux as an addition of a discretized value of motor induced voltage. CONSTITUTION:A computing element is provided to operate the expression, which is composed of adders 1a, 1b and 1c, coefficient multipliers 2a, 2b and 2c, sample hold circuits 3a and 3b and a timing circuit 4. This expression shows that the flux phi'(tn+1) of time constant tn+1 after time  t is operated from the flux phi' (tn) of time constant tn, voltage V1(tn) and current i1(tn). Using these relations, the operation of the flux phi is performed. Thus, the motor flux is found as an addition of the discretized value of the motor induced voltage by the use of coefficient multipliers and adders, so that it is possible to detect the flux stable and highly precise in the overall speed range of the motor.

Title: Generating device for speed equivalent signal
Inventor: TATE SEISAKU
IPC: G01P21/02
Filed: 1981-08-05
Abstract: PURPOSE:To perform a test motion coinciding with a real motion, by a method wherein an internal impedance of a speed equivalent signal generator is caused to coincide with a real speed signal source impedance. CONSTITUTION:An equivalent sine wave signal generating part 1 outputs a signal equivalent to a signal source generating a frequency paralleling a speed. The output signal is transferred to a device 4 to be tested through a power amplifier 2 and an output transformer 3. A series reactance 17 is connected between the output transformer 3 and the device 4 to be tested so that an impedance from the side of the device 4 to be tested is equal to that of the speed signal source. This permits the equivalent signal to be generated in a shape which prevents damaging of a load characteristic.

Title: Lens for correcting chromatic aberration and optical head formed by using the same
Inventor: YAMAGATA MICHIHIRO
IPC: G02B13/18
Filed: 1994-06-06
Abstract: PURPOSE:To provide a lens for correcting chromatic aberrations capable of sufficiently correcting the chromatic aberrations with two elements a set of lenses and an optical head formed by using the same. CONSTITUTION:This lens 1 for correcting the chromatic aberrations is used in combination with an objective lens 2 for the optical head. The chromatic aberration correcting lens 1 is a combined lens formed by sticking one element of positive lens and one element of negative lens. Further, the chromatic aberration correcting lens 1 is constituted to satisfy both equations 0<r1Xr3/f0<500, 0.8<r1/r3<1.2 when the radius of curvature on the light source side face of the chromatic aberration correcting lens 1 is defined as r1, the radius of curvature on the exit side face as r3 and the focal length of the objective lens as f0. As a result, the fluctuation in wave front aberrations is suppressed even if the spacing between the chromatic aberrations correcting lens 1 and the objective lens 2 is fluctuated by the movement in the optical axis direction of the objective lens 2 while the axial chromatic aberrations of the objective lens 2 by a fluctuation in the wavelength of the light source is well corrected.

Title: Analog switch
Inventor: KIKUCHI HIROYUKI
IPC: H03K17/60
Filed: 1986-05-30
Abstract: PURPOSE:To eliminate the leakage of the switch control signal component by securing an equal DC level between the ON and OFF modes of a switch. CONSTITUTION:In an OFF mode of a switch, a cornet ir flowing to a transistor TRQ2 flows to a TRQ1 with a deferential circuit 1 in its ON mode. Thus the current ir does not flow to the TRQ2. While the current is switched in a differential circuit 2 and a current equal to a current i8 flowing to a constant current circuit 2 consisting of a TR Q8 and a resistance 5 flows to a TR Q6. The DC current irDC flowing to the TRQ2 in an ON mode of the switch is equal to 1/2 of the current i5 flowing to a current circuit 1 consisting of a TR Q5 and a resistance R4. Thus an equal DC level is obtained between the ON and OFF modes of the switch by setting the current i8 is set at 1/2 current i5. Then the leakage of the switch control signal component is eliminated.

Title: Motor
Inventor: AMAIKE SUSUMU
IPC: H02K5/173
Filed: 1997-05-14
Abstract: PROBLEM TO BE SOLVED: To easily reduce galvanic corrosion which occurs in bearings by providing roler bearings filled with a low-viscosity grease. SOLUTION: A motor is provided on its load side with a roller bearing 4a filled with a grease which is lower in viscosity than that in a bearing 4b on the anti-load side. Although in this case the roller bearing 4a filled with the lower-viscosity grease is placed on the load side, no problem is posed if the roller bearing 4a is placed on the anti-load side. If three or more bearings are used, the bearings may be arranged in any way, as long as one of the bearings is a roller bearing filled with a viscosity grease lower than those filled in the other bearings. Low-voltage discharge is repeated on the load-side bearing 4a by employing the roller bearing 4a, because the discharge energy per unit area is low and because the oil-film breakdown voltage is reduced. The discharge energy itself can be lowered because of low voltage. Therefore, galvanic corrosion can be reduced.
