Filed: 1989-02-18
Abstract: PURPOSE:To form a homogeneous film in the width direction on a wide base plate by generating annular plasma beams by a hollow cathode gun and flattening the annular plasma beams by a magnetic field generator and irradiating an evaporating source with the flattened plasma beams. CONSTITUTION:The hollow cathode 1 of a hollow cathode gun is constituted of a cylinder 1A and a column 1B and plasma beams 2 are generated which are annular and low in plasma density of the center part. Then the plasma beams 2 are flattened by a magnetic field generator 3 which consists of the oppositely arranged magnets 3A, 3B while holding the prescribed interval. An evaporating source 6 which is introduced into a crucible 5 lengthened in the width direction of a base plate is irradiated by the flattened plasma beams 4 and a vaporating flow analogous to the beam shape is formed. Further the hollow cathode is preferably formed of one or more kinds selected among from Ta, W and LaB6. Thereby a film can be vapor-deposited which has uniform thickness in the width direction of the base plate. The plasma beam generator is favorable to continuous vapor depositing treatment for a wide long-sized material.

Title: Cylindrical multiblade fan
Inventor: WAKABAYASHI YOICHI
IPC: F04D29/28
Filed: 1990-02-20
Abstract: PURPOSE:To enable noise level reduction via the improvement of wind cutting with a thin-walled vane, and the vibration and sound absorbing performance of a vane support plate by forming both of the vane and vane support plate with a thin steel plate, and the vane support plate with a steel plate covered with an elastic material. CONSTITUTION:A cylindrical type multiblade fan is constituted with a vane support plate 1, a vane 2 and side plates 3 and 4 at both sides thereof. The vane 2 is made of a thin steel plate, and cover layers 5 and 6 such as rubber related to an elastic material are provided on both surfaces of a thin steel plate 7 forming the core of the vane support plate 1. Due to the application of small wall thickness to the vane 2, a flow velocity drop and turbulence between vanes can be reduced and an air volume can be increased while lowering a noise level. In addition, vane thickness is reduced by 1/2 to 1/3, compared with a conventional aluminum make, and material cost can be thereby reduced.

Title: Ignition timing control device for internal-combustion engine
Inventor: HARAGUCHI HIROSHI
IPC: F02P5/153
Filed: 1982-03-10
Abstract: PURPOSE:To perform acceleration smoothly by judging as an acceleration state when multiple knocks occur in succession at a short interval to increase the spark advance speed and by judging that a stationary state is attained based on the subsequent spark advance state and knock sensor information to decrease the spark advance speed. CONSTITUTION:An ignition time control circuit 8 consisting of a microcomputer judges as an acceleration state when multiple knocks occur at a short interval to increase the spark advance speed, because in a stationary state knocks due to signals 7 occur at a long interval and multiple knocks do not occur in succession, even if at a short interval. The spark advance target value is made the basic ignition time based on the base map, but the knock limit ignition time of the stationary state is passed before the target ignition time is attained, thus generating a knock signal 7. Therefore, if the spark advance speed is decreased when a knock occurs or a predetermined number of knocks occur, a stable control condition under the stationary state can be smoothly attained. It is further effective to delay the starting time to increase the spark advance speed a little, because knocks in the acceleration pass reliably during the delay.

Title: Fan locking mechanism for air conditioner
Inventor: UDA TOSHIO
IPC: F04D27/00
Filed: 1987-02-23
Abstract: PURPOSE:To prevent any reverse rotation of a fan due to a current, by forming a disc in a turning shaft for a propeller fan of an outdoor motor, installing a disc brake there, and locking it during suspension of motor rotation but unlocking it during rotation. CONSTITUTION:A disc 4 is formed in a shaft of a propeller fan 3 for an outdoor motor of an air conditioner, and a disc brake is installed in one spot of the outer circumference. Since a magnet 8 of this disc brake is energized with a continuous rating current during motor operation, a movable shoe 6 comes off the disc 4 and the propeller fan 3 rotates in a normal state. During operation suspension, the magnet 8 comes to nonenergization, and the movable shoe 6 is strongly pressed to the disc 4 by a compression spring 7, thus the propeller fan 3 is locked. Accordingly, at the time of operation suspension, even if a wind blows, the propeller fan is in no case reversely rotated, so that wear and tear in a bearing for the motor is as negligible, and at the time of starting, excessive load is not applied on the motor.

IPC: G03B7/24
Filed: 1996-01-31
Abstract: PROBLEM TO BE SOLVED: To surely preserve already photographed content without causing double exposure and the like compared with the case of setting display on 'the midway of exposure' by setting the display content of a display means showing an exposure state as a exposed state at rewinding, when winding operation is not normally performed. SOLUTION: When abnormality is caused during winding up of a film, for failure processing, a motor M16 is braked so as to stop winding, then the failure of winding is displayed, and rewinding process is performed. Thereafter, the cartridge state display (stop phase) in a display means of a cartridge is set in the exposed position. Because the failure is caused by the motor M16 stop or abnormality of write during winding of the film, the possibility of defective magnetic record or the like is high. Consequently, it is a problem to display to be on 'the midway of exposure' at which the heading of an unexposed frame is performed according to the existence of a magnetic signal, and it is desirable to set in 'exposed state'.
