Title: Semiconductor circuit unit for power supply
Inventor: SETO TAKESHI
IPC: H01L23/46
Filed: 1987-07-08
Abstract: PURPOSE:To facilitate incorporation into an equipment by installing a semiconductor circuit for power supply to a heat sink with a fan and a fan motor and changing these apparatus into a unit including even a board having a connecting terminal with an external circuit. CONSTITUTION:A fan 2 belongs to one kind of centrifugal fans, and air is sucked to the upper section of the fan 2 bored to a heat-sink upper plate 8 from a suction hole, and forwarded to the outer circumferential section of the fan 2. Air fed by the fan 2 is introduced to a semiconductor circuit 5 for power supply along the flow path of a heat sink 1 with cooling fins. Air cools the semiconductor circuit 5 for power supply and the heat sink 1 with the cooling fins in a process in which air passes through the fin section for the heat sink 1 with the cooling fins and is discharged outside a semiconductor circuit unit for power. Accordingly, the semiconductor circuit for power supply is incorporated easily into an equipment, thus miniaturizing a device, then simplifying maintenance.

Title: Enclosed type storage battery
Inventor: WADA YASUNAO
IPC: H01M10/12
Filed: 1990-06-29
Abstract: PURPOSE:To realize a high capacity storage battery with its thickness reduced by forming the structure of the battery in such a way as arranging an electrolytic solution retainer on both sides of an electrode group. CONSTITUTION:By means of such a structure that electrolytic solution retainers 14a, 14b are arranged on both sides of electrode group 11, a piercing member 5 is fixed to the electrode group 11 with its end part caught in flexible electrolytic solution retainer and is not protruded both sides. Since electrolytic solution is held in the retainer, the retaining amount of the electrolytic solution can be maintained even if the retainer inside the electrode group is made thin and the thickness of the electrode group can be made thinner than the conventional battery. Since the retainers on both sides act as shockabsorber, the electrode is not damaged even when applied pressure is strengthened, so that the high capacity storage battery can be obtained.

Abstract: PROBLEM TO BE SOLVED: To facilitate the manufacture of a polarizing beam splitter by setting an incident angle to the polarized light separating plane of the polarizing beam splitter for separating a light beam reflected from an optical disk within a specified angle range. SOLUTION: Collimated light flux Q1 passed through a polarized light separating plane 16 of a polarizing beam splitter 13 is converged on an information recording surface 18a of an optical disk 18 by an objective lens 17 and is reflected on the information recording surface. Reflected light Q2 as the reflected light beam is again converged to the objective lens 17 and is guided to the polarized light separating plane 16 of the polarizing beam splitter 13.

Abstract: PURPOSE:To judge whether or not a call is the one mutual between radio telephone sets within the same base by a base station and to connect radio bases each other without a public network. CONSTITUTION:The radio control part 27 of the base station 34 receives the call origination request of the radio telephone set 33 and a management part 32 collates the ID of the telephone set 33 of the call origination request received by the control part 27 and the IDs of the telephone sets 33 stored and held in the management part 32 of the station 34. At the time of not matching with the ID of the telephone set 33 stored and held by the management part 32, the station 34 performs a normal call origination operation. When the call origination request is the one to the telephone set 33 managed by the management part 32 of the station 34, the control part 30 of the station 34 does not send the call origination request to the public network 35, sends out a call termination request to the present area and receives a response from the telephone set 33 of an incoming call destination. In such a manner, the call between the telephone sets 33 within the same base station 34 is realized. As mentioned above, when the call of the radio telephone sets within the same station is judged, radio base stations are connected each other without the public network and the need of a line using fee by public network connection is eliminated.

Title: Control device in banknote pay-off device
Inventor: FUKUDA SHINJI
IPC: B65H3/06
Filed: 1984-08-18
Abstract: PURPOSE:To maintain the pay-off pressure always constant to apply a uniform and sufficient pressure onto several parts of a banknote, thereby it is possible to prevent the banknote from skewing, by providing a stop control means for stopping the pay-off of banknotes when a pressurizing means is operated in accordance with a signal from a pay-off pressure detecting means. CONSTITUTION:Several banknotes 3 are successively paid of, the pay-off pressure between the banknotes 3 and a pick roller 2 lowers, and when the pay-off pressure lowers below a predetermined pressure, the position of one end P of a cranklever 9 is lowered to depress a microswitch 4 which is therefore turned off. Further, a turn-on and -off detecting part in a control section 6 detects this condition and issues an L-level signal. After the L-level signal is turned into a H-level signal, a pressurizing motor 12 increases the pay-off pressure. Meanwhile, when the L-level signal from the detecting part is delivered to an AND gate in a stopping control means, a pulse signal from a signal generator is blocked, and therefore, a pay-off motor 7 is not energized during the L-level signal is sustained. When a pressurizing bed 15 is raised to turn on the switch 4, the detecting part 18 again issued the H-level signal, and therefore, the motor 12 is deenergized while the motor 13 is energized.
