Title: Power supply circuit with battery
Inventor: SAGANE TOMIYASU
IPC: H02M3/28
Filed: 1997-10-07
Abstract: PROBLEM TO BE SOLVED: To eliminate the charging-current limiting circuit of a power supply circuit with a battery and reduce its consumption power, making single its continuously operated DC-DC converter, by charging via a rectification means the battery with the excitation energy stored in the main transformer of its DC-DC converter when its switching transistors are in OFF-states. SOLUTION: Inputting to a DC-DC converter 2 a first DC voltage outputted by a rectifying and smoothing circuit 1, second DC voltages are generated to feed them to load apparatuses 7, 8. Also, when an input AC power supply is interrupted or its voltage falls below the predetermined changing range thereof, using a battery 4 as a power supply and connecting it with a boosting circuit 6 via a shunt regulator 5, a third DC voltage outputted by the boosting circuit 6 is inputted to the DC-DC converter 2 to generate the second DC voltages. Still, the battery 4 is charged via a rectification circuit 3 with the excitation energy stored in the DC-DC converter 2.  As a result, eliminating any charging- current limiting circuit, the circuit scale of a power supply circuit with a battery is reduced, and also, making single the continuously operated DC-DC converter 2, its consumption power is reduced.

IPC: H04N13/04
Filed: 1992-09-18
Abstract: PURPOSE:To attain the stereoscopic vision from many directions by giving an electric signal to a polarized filter comprising three layers so as to vary the transmission angle of a light periodically thereby assigning left and right eye use video images to the left and right eyes respectively. CONSTITUTION:A polarized filter is of three-layer structure each comprising polarized planes A-C, the phases of the planes A, B differ 90 deg. from each other, and the plane C is electrically switched to the planes A, B synchronously with the switching of the video image. The polarized plane C3 of the filter 4 is switched in the order of A-B-A..., and the polarized plane C3 of the filter 5 is switched in the order of B-A-B... sequentially. When only the filters 4, 5 exist, a filter 6 blocks the right eye use video image made incident in the direction of the left eye 10. The switched 1st stage of the filter transmits the right eye use video image 7 in the direction of the right eye 11, and the 2nd stage transmits the left eye use video image in the left eye direction. The two operations are implemented synchronously with the left eye and right eye use video images displayed alternately at the speed of a prescribed frequency Hz or over.

Patent JP-S63121996-A (JP)
Title: Coin processor
Inventor: TOOMASU KUROSUMAN
IPC: G07F5/22
Filed: 1987-10-30
Abstract: The coin handling system prevents coin to coin contact taking place in coin operated equipment. This is achieved by an arrangement whereby the presence of a coin activates a lever which then prevents a subsequent coin touching the previous one. A series of such levers are employed in the coin store of coin operated equipment, the actual number depending upon the number of coins to be stored. When the first coin is cleared from the store by a suitable gate arrangement, all coins move along the store by one position, the separation being maintained by the interaction of the levers and coins. The advantages of the system are that a wider range of coins from one coin set can be accommodated in a single store than is presently possible. The coin insertion sequence is maintained for the purposes of microprocessor control since a single store is used. Since coins cannot overtake each other the risk of coin jams is lessened.

Filed: 1986-11-18
Abstract: PURPOSE:To prevent a circulation filter from getting into a dust source when a spindle rotates by providing the circulation filter in the space between a spindle shaft and a spindle hub and fixing the circulation filter to a first housing base. CONSTITUTION:The circulation filter 6 is provided in the space between the spindle 9 and the spindle hub 7, and the circulation filter 6 is fixed to the first housing base 11. Air flow in a head disk assembly 12, which is completely sealed up and surrounded by the first housing base 11, a second housing base 10 and a cover, forms a negative pressure part near the center of a spindle 8 as arrows show. Clean air which passes through the circulation filter 6 goes through a spindle hub opening part 7a and spacing opening part 5a and flows to the spaces between magnetic disks 1. The air which flows to the paces between the magnetic disks 1 backward in their radius direction forms an air flow loop flowing into the circulation filter 6. Thus the air flow can keep the state of cleanliness.

A speed detector detects the speed by computing the output signal change of the light receiving pattern forming means due to the movement of the moving body, and a speed controller receives the signal of the speed detector and controls the elevator car. As the countermeasure of the joints of the fixed members, the joints are filled up with fillin-up members. It is so installed that two sets of laser transmitting means 30 do not irradiate the joint at the same time, and the mutual joints of the first fixed member and second fixed member installed parallely in the elevator shaft are disposed alternately.

Filed: 1984-12-28
Abstract: PURPOSE:To obtain a thin and uniform lubricating oil film without hindering the recording and reproducing action by impregnating previously a nonwoven fabric to cover the surface of a main body with lubricating oil. CONSTITUTION:Both surfaces of a magnetic recording medium main body 1 are covered with nonwoven fabrics 5 and 6, and the main body is placed in a case 7. A fluorine lubricating oil is firstly dissolved into a fluorine soln. at <=0.5% concn., and the nonwoven fabrics 5 and 6 are immersed into the soln. for about 2min. Then the nonwoven fabrics 5 and 6 are pulled up, and dried for about 1hr. Consequently the inside of the nonwoven fabrics 5 and 6 is uniformly impregnated with the lubricating oil. Then the nonwoven fabrics 5 and 6 are assembled. Both surfaces of the recording medium main body 1 are brought into sliding-contact with the nonwoven fabrics 5 and 6 by the revolution of the magnetic recording medium main body 1, and hence the lubricating oil impregnating the nonwoven fabric is thinly coated on both surfaces of the recording medium main body 1. In this case, since the recording medium main body 1 is always in sliding-contact with the nonwoven fabrics 5 and 6, the thin film of lubricating oil having uniform thickness can be obtained.
