Title: Paper feed controller
Inventor: ISHIMATSU HIDEAKI
IPC: G06K15/16
Filed: 1985-12-18
Abstract: PURPOSE:To detect the condition of a printing paper and prevent overlapped printing from occurring, by providing a printer with a paper feed detecting part and a paper feed driving controlling part. CONSTITUTION:Upon receiving a controlling signal, a paper feed driving part circulatively move a paper-feeding belt, whereby paper-feeding projections are engaged into holes 10 of a printing paper to feed the paper. A light-emitting part 7 is supplied with a syncyronizing signal from a paper feed driving controlling part, and sends the signal to a light-receiving part 8 as optical and electrical signals. When the printing paper 9 is caught in a printer so that it is not fed while the paper-feeding belt is circulatively moved, the hole 10 is broken, and an optical signal reaches the light-receiving part 8. Only when both of the signals reaches the light-receiving part 8, the part 8 judges that the printing paper 9 is caught in the printer, and a signal indicative of the detection of the caught condition of the paper is sent from the light-receiving part 8 to the paper feed driving controlling part, which sends a control signal for stopping printing to a printing part.

Title: Centrifugal fan and air conditioner equipped with the same
Inventor: HOKOTANI KATSUMI
IPC: F24F1/00
Filed: 1996-10-28
Abstract: PROBLEM TO BE SOLVED: To provide an air conditioner capable of making uniform as far as possible an air velocity distribution passing through a heat exchanger and obtain centrifugal fan suitable for the air conditioner. SOLUTION: An outer peripheral part 1a located on the side of a fan blowoff outlet 5 of a hub 1 is slantingly provided such that it is displaced toward a fan suction inlet 4 side as it goes radially outwardly. In the construction, blowoff air from the fan blowoff outlet 5 is guided to the outer peripheral part 1a of the hub 1, and is deflected so as to approach a suction inlet 4, the blowoff direction being more inclined to the suction inlet 4 side than a surface perpendicular to a shaft center of a centrifugal fan X1, and air velocity distribution of the blowoff outlet 5 is slightly displaced to the suction inlet 4 side.  Accordingly, even when in an air conditioner including the centrifugal fan X1 the centrifugal fan X1 and a heat exchanger 10 disposed on the outer peripheral side of the former are constructed, displaced in an axial direction of the fan, blowoff air from the centrifugal fan X1 is directed to a center part 10a of the heat exchanger 10 to the utmost, and hence the velocity distribution of air passing through the heat exchanger 10 is made uniform over the entire region of the heat exchanger as far as possible.

Title: Separately-excited inverter circuit
Inventor: SUGAO IKUYA
IPC: H02M7/537
Filed: 1986-11-28
Abstract: PURPOSE:To prevent a danger from occurring by providing a diode between the primary winding of an oscillation transformer and a transistor to prevent a flyback current when a signal circuit stops an oscillation signal to effectively stop the oscillation. CONSTITUTION:An inverter circuit comprises a transistor (Tr) 2, an oscillation transformer 3, and a resonance capacitor 6. A signal circuit 8 has Trs, 9, 10 and a diode 11, and alternately turns ON and OFF the Trs 9, 10 to drive the Tr 2. In this case, a diode 18 is provided between the primary winding 4 of the transformer 3 and the transistor 2 to eliminate a flyback current. Thus, when the output of the circuit 8 is eliminated to stop the inverter circuit, the flyback current is prevented by the diode 18. As a result, after the output of the circuit 8 is stopped, the Tr 2 is not turned ON to prevent a self-excited oscillation mode.

Title: Sewage construction
Inventor: MOTOYAMA ATSUSHI
IPC: E03F5/00
Filed: 1992-09-30
Abstract: PURPOSE:To reduce load for sewage disposal by increasing the amount of dissolved oxygen in sewage to improve the quality of water midway in a sewage pipe through which sewage flows. CONSTITUTION:A compressor is operated to open a valve 16 for blowing air 22 upwards from a blowing port 12 and mixing air 22 into sewage 20 filled into a lifting pipe 7. By this, the density of sewage 20 in the lifting pipe 7 becomes lower apparently than that in a suction pipe 6. Then sewage 20 in the suction pipe 6 flows from a suction port 7a into the lifting pipe 7, and returns from the upper exhaust port 7b into a sewage pipe 2. When this flow reaches a specified flow velocity, a valve 15 is opened to blow air 22 downward from a blowing port 11. The air 22 lowers to a suction pipe bottom part 6b, and dissolves in sewage 20, which increases the amount of dissolved oxygen to increase the quality of water.

Title: Automatic focusing device and focusing method
Inventor: OGAWA MASAHIRO
IPC: G03B13/36
Filed: 1998-09-22
Abstract: PROBLEM TO BE SOLVED: To shorten the time required for focusing and to improve focusing accuracy. SOLUTION: A focusing lens is firstly moved to a lens position in accordance with range-finding data (S2) when the range-finding by an AF sensor is executed (yes at S1) by this focusing method. The focusing lens moved is successively moved to a position at which a contrast value is set to be maximum (S3). On the other hand, when the range-finding is not executed, the contrast value is detected and stored for each lens position (S4), and the focusing lens is moved to the lens position at which the contrast value is set to be maximum (S5), and the processing of a step S3 is executed. Thus, useless movement of the focusing lens during automatic focusing is eliminated, and also the positional deviation of the focusing lens due to the temperature environment of the focusing lens or the mechanical deviation of a driving mechanism or the like is eliminated.
