Title: Air conditioner
Inventor: TATSUMI TOSHIAKI
IPC: F24F5/00
Filed: 1992-02-21
Abstract: PURPOSE:To prevent generation of drift by a method wherein a control plate is provided in a large space part, which extends by a prescribed length concentrically with an axial fan toward an instrumental direction from a part opposing to arm instrument in a casing. CONSTITUTION:In a large space part 6a in a ring-shaped passage formed on an exterior periphery on suction side of an axial fan 4, a control plate 8 is provided, which extends concentrically with the axial fan 4 toward a direction of an instrument 5 from a part opposing the instrument 5 in a casing 1. By this, as airstream flowing on the exterior peripheral side of the axial fan 4 is pressed by the control plate 8, it flows smoothly. Therefore, any large vortex which is to be generated in the large space part 6a is broken by a tip end of the control plate 8, so that pressure is raised in local places where pressure is low. Thus, generation of drift can be restricted on the suction side.

IPC: H04N1/29
Filed: 1993-02-24
Abstract: PURPOSE:To provide an electrophotographic device capable of shortening the 1st sheet printing time by allowing an electrostatic charging means to start impressing a high voltage so that a scanner unit and a photosensitive drum can attain a state where normal exposing operation and normal sensitizing operation can be performed at the same time.

When the starting instruction of printing is given, the rotation of the scanner motor is started, and a timer is started. When the difference time described above has elapsed, the high voltage is impressed on an electrostatic charger 15 from a high voltage power source unit 41 so as to electrostatically charge the photosensitive drum 18. Thus, the scanner motor and the photosensitive drum 18 are shifted to the normal operation performable state at the same time.

Filed: 1989-02-15
Abstract: PURPOSE:To adjust a drain voltage of each FET with one variable resistor only with well balance simultaneously while keeping a drain current constant by providing a transistor(TR) for setting a drain voltage is series with the drain circuit of a FET. CONSTITUTION:A drain current of the FET is set by the regulation of a base voltage of a TR 1 and a drain voltage of the FET is set by the regulation of a base voltage of a TR 2. Then an emitter of the TR 1 connects to a drain of the FET and the collector connects to a power supply via a resistor R4 and a voltage lower than the power supply is supplied to the base. Then the TR 1 is of opposite polarity with respect to the TR 2 whose emitter connects to the collector of the TR 2, whose collector connects to the gate of the FET and whose base receives a prescribed voltage. Thus, the drain current IDS of the FET1 is set by a base voltage VB1 of the TR 1 and the resistance of the resistor R4 and the drain voltage VDS is set independently of the drain current IDS by regulating the base voltage VB2 of the TR 2.

Title: Scanner device and its control method
Inventor: KODAIRA TAKAKI
IPC: G06T1/00
Filed: 1997-02-19
Abstract: PROBLEM TO BE SOLVED: To call attention of an operator and to improve the using facility of a scanner device by inhibiting an image processing means from fetching the image data on another film as long as the loading of a film is detected by one of plural detection means. SOLUTION: The control is applied to inhibit the loading of another type of film before the processing of an APS film, for example, is over even though an operator tries to mount a continuous film unit or a slide film unit in order to process a 135 film. A CPU 323 decides the type of film under processing based on the detection signals of a sensor K3 serving as a bar code, a CF presence/absence sensor K4 and an original presence/absence sensor K2. When no specific film is processed, the type of the film loaded into a scanner device is decided. Then a subroutine program is carried out for the film image processing when the 135 film is loaded.

Title: Oxygen dissolution device
Inventor: ARAKI SHINPEI
IPC: C02F3/26
Filed: 1992-02-21
Abstract: PURPOSE:To ensure that oxygen becomes dissolved in the interior of a stored water rather than the free water level of the stored water by forming an oxygen-filled space using a tank for filling oxygen and the free water level of a stored water in a storage tank, and filling this oxygen-filled space with oxygen under a pressurized condition. CONSTITUTION:A tank for filling oxygen 2 with only an open lower end is arranged in a water storage tank 1, and an oxygen-filled space S is formed using the tank for filling oxygen 2 and the free water level of a stored water W in the water storage tank 1. Oxygen is injected into the oxygen-filled space S under a pressurized condition to allow oxygen to be dissolved in the stored water W rather than the free water level of the stored water W. Further, the dissolution density of oxygen in the stored water W is adjusted by controlling a pressure force to the oxygen. Thus, water containing oxygen of desired concentration is obtained.
