Title: Inverter device
Inventor: FUJII HIROSHI
IPC: H02M7/48
Filed: 1989-04-28
Abstract: PURPOSE:To have stable output relative to varying ambient temp. by arranging circuit parts so that those with inverter output rising for rising temp. are located close to those with the inverter output sinking. CONSTITUTION:A current transformer 7 is located close to a Zener diode 13 for production of the reference voltage. When this current transformer 7 gets high temp. to quicken saturation of its core, the frequency rises and the photo output drops, and with respect to it the Zener diode 13 raises the output of an inverter circuit relative to temp. rise. This close location of the parts to one another stabilizes the photo output against the varying ambient temp.

Abstract: PURPOSE:To reduce mistakes in reading information and also to identify a camera not having the function of imprinting data on the outside of a photographic picture by a laborator system by always imprinting the data in an on-state to a specified bit on a part between perforations. CONSTITUTION:In the case of reading the data imprinted on the part between the perforations 212 by the laboratory system, data LED.S (1,1), (3,1), (1,8) and (3,8) in the four corners are always in the on-state, then, by taking them as reference the variance in a data imprinting position and the width, etc., can be corrected and accurately read based on the data at the time of reading the data. Thus, the mistakes in reading the data can be reduced and also the camera not having the function of imprinting the data between the perforations 212 can be easily identified because four bits in the four corners are not in the on-state.

Title: Bearing oil sealing device for vertical rotating electric machine
Inventor: YAMASHITA YUKIHIRO
IPC: F16C33/66
Filed: 1996-04-26
Abstract: PROBLEM TO BE SOLVED: To prevent lubricating oil from flowing out of an oil tank by forming a protrusion at the outer periphery part of a bearing runner which is disposed in the oil tank and fixed on the rotating shaft of a dynamo-electric machine. SOLUTION: A bearing runner 2 rotates, oil 4 moves up along the inner periphery of the bearing runner 2 in a clearance between the bearing runner 2 and an oil weir 5 by means of centrifugal force by oil viscosity and rotation. When the oil 4 which has moved up reaches an oil return hole 9 in the bearing runner 2, the oil passes through the oil return hole 9, swung away and returned to an oil tank 7 by centrifugal force. A part of oil 4 moves up further at the outer periphery of the bearing runner 2 and reaches the lower surface of a disc-shaped protrusion. The oil 4 which has reached the lower surface of the protrusion 10 passes through a groove part 11 and swung away by centrifugal force from a V-shaped groove 12.  The V-shaped groove 12 is constituted so that its outside may become narrower gradually, therefore, the oil film of the oil 4 becomes thicker as it moves in the outward direction of the disc- shaped protrusion 10, and the oil is formed into oil drops at the outer end part of the disc-shaped protrusion 10. It is thus possible to facilitate swinging by centrifugal force.
