Title: Linear power amplifier
Inventor: TAKINO TAKANORI
IPC: H03F1/32
Filed: 1993-02-09
Abstract: PURPOSE:To obtain a high power efficiency while keeping an excellent linearity without addition of a complicated circuit especially by equally bisecting an incident wave into two, inverting the polarity of one of the two divided signals, combining amplified outputs in class B amplification while the polarity of the outputs is made opposite to each other and extracting the combined output. CONSTITUTION:An incident wave is equally bisected by a branching circuit 1 and the polarity of one of the two equally divided signals is inverted by a polarity inversion circuit 3 and inputted to power amplifiers 2, 4 whose amplification factor is equal to each other. A bias voltage is applied to the power amplifiers 2, 4 so as to be operated in the operating state close to the class B amplification. The positive polarity of an input waveform is linearly amplified in either of the power amplifiers 2, 4, the negative polarity portion is cut off, and the operation in the other of the power amplifiers 4, 2 is reversed to the above-mantioned operation. Then the positive portion and the negative portion of the incident waveform are synthesized while being amplified with excellent linearity by synthesizing the outputs of the power amplifiers 2, 4 so that the polarity of the outputs is made opposite to each other.

Title: Epicyclic reduction gear
Inventor: OGATA SEISHIROU
IPC: F16H1/32
Filed: 1987-02-27
Abstract: PURPOSE:To absorb variations in rotation with the use of mechanical feed-back by making an external gear provided on an eccentric member mesh with a carrier gear, and by constituting a closed loop with the use of a planetary type epicyclic gear mechanism and an internal contact type reduction gear. CONSTITUTION:When an error in rotation, or, for example, an advance in phase, occurs on an internal gear 8 as an output section, with respect to an input shaft 1 on rotation at a constant speed, an internal sun gear 23 in a planetary type epicyclic gear mechanism shifts in synchronization therewith, but since a carrier gear 24 is rotated in the same direction, an eccentric member 18 is pushed in the same direction as that of rotation of internal gear 8 through the intermediary of an external gear 19 meshed with the carrier gear 24. With this arrangement, a negative feed back is applied to an internal contact type epicyclic reduction gear composed of external gears 51, 52, the internal gear 8 and the like, and therefore, the rotation of the external gear 19 (eccentric member 18) as an input shaft is retarded. Thus, errors in transmission and variations in rotation occurring in the reduction gear or variations in rotation due to resonance occurring in the mechanism in its entirety may be restrained or prevented.

Title: Regeneration of ion exchange resin mixture
Inventor: SAITO TAKAYUKI
IPC: C02F1/42
Filed: 1986-03-05
Abstract: PURPOSE:To enable the sufficient separation of an anion exchange resin and a cation exchange resin and to enhance the quality of treated water from a desalting tower, by repeating operation for transferring both ion exchange resins between a resin separation tower and each regeneration tower. CONSTITUTION:Because a cation exchange resin gathers to the bottom part of an anion regeneration tower as a matter of course after backwashing separation, only the anion exchange separation, only the anion exchange resin of the bed above the anion exchange resin draw-out port positioned in the anion exchange resin bed is drawn out to be transferred to a resin mixing tower 11 through an anion exchange resin transfer pipe 12. Therefore, a minute amount of the Na<+>-form cation exchange resin generated by the regeneration of the anion exchange resin is not carried into the resin mixing tower 11 along with the anion exchange resin allowed to remain in the bottom part of the anion regeneration tower in a predetermined amount. After the finish of transfer, the residual resin is transferred to a resin separation tower 1 from the anion regeneration tower 2 by a transfer pipe 16.

Title: Stop controller for guided unmanned truck
Inventor: SHIMOKATA HIROSHI
IPC: G05D1/02
Filed: 1983-03-18
Abstract: PURPOSE:To decelerate and stop assuredly and precisely an unmanned truck by decelerating and stopping the truck when the traveled distance measured from the specidic position on a traveling route attains to the distance where the deceleration is started. CONSTITUTION:A guide line 1 is provided on the floor surface of a traveling route, and an unmanned trunk 2 has an automatic steering while detecting its lateral displacement degree to the line 1. Then the truck 2 stops at sop positions P1-Pn respectively. The stop marks M1-Mn are put at the positions P1-Pn respectively. A detector 8 detects these marks and also a mark M at a specific position P. The distance traveled from the position P is measured 10. A setting device 11 sets the distances between the position P and the deceleration starting positions P'1-P'n which are set before positions P1-Pn. When the measured (10) value reaches this set distance, a deceleration command from a deceleration command device 13 is outputted to a control circuit 12 of a driving motor. Thus the truck 2 is decelerated.
