Title: Fluid bearing
Inventor: KUBO TADAYUKI
IPC: F16C32/06
Filed: 1990-06-05
Abstract: PURPOSE:To prevent contact caused by the deformation of a rotary element during its rotation in a thrust bearing part by establishing a thrust bearing clearance during the stoppage of the rotary element so that the deformation of the rotary element during its rotation can not bring a bearing surface and the rotary element into mutual contact in the thrust bearing part. CONSTITUTION:In the case where the change caused by the rotation of a rotary element of a minute clearance 10 to a thrust plate 1 before rotation is denoted by  X, and a clearance designed for a target bearing performance by CO, the width C of the minute clearance 10 is established as shown by the expression of C=CO+ X. Thus, even if the high speed rotation of a rotor 2 makes the face la of the thrust plate 1 fall toward a bearing face 4, which does not come into contact with the thrust plate 1 to prevent the seizure of a bearing and the lowering of rotational accuracy.

Filed: 1996-06-07
Abstract: PROBLEM TO BE SOLVED: To provide an information recording and reproducing device, which can record/reproduce the recording media having the different recording method without enlarging the scale of an optical system. SOLUTION: The space of an optical path to an objective lens 2 is separated, and respective special semiconductor lasers 5 and 6 are switched in correspondence with the recording methods of a recording medium 1. Furthermore, the space of an optical path other than a freely rotatable reflecting mirror and the objective lens 2 is separated. The respective special optical paths are selected by switching the supporting angle of the above described reflecting mirror in correspondence with the recording method of the recording medium 1. Furthermore, the space of the optical path other than the objective lens 2 is separated. Thus, the respective special optical paths are selected by rotating a pedestal in correspondence with one recording method of one recording medium 1.

Abstract: PURPOSE:To prevent malfunction caused by a linear vibrational input by selectively making ports communicate mutually according to the rotation of a guide valve provided in a circular opening of a housing, and providing pressure chambers to severally drive the guide valve in one and its opposite directions through a nozzle flapper. CONSTITUTION:Permanent magnets 32A, 32C and electromagnetic coils 33A, 33B rotate a nozzle flapper 4 through an armature 34 to change the opening areas of nozzles 52A, 52B, 62A, 62B for driving a segmental guide valve 2 provided in an inside housing 12 through pressure chambers 5A, 5B, 6A, 6B. The nozzles 52A, 52B, 62A, 62B are thereby returned to their original opening areas to make the guide valve 2 take a rotational position according to input currents applied into the electromagnetic coils 33A, 33B. Thus supply ports 13A, 13B, control ports 15A, 15B and return ports 16A, 16B are changed over. The guide valve 2 can therefore be prevented from malfunction caused by linear vibrational input, and can steadily function under the large vibration of a vehicle or the like.

IPC: H04N17/00
Filed: 1990-06-05
Abstract: PURPOSE:To exactly specify a television viewing channel by specifying the television viewing channel by detecting a luminescent line signal to actually appear on the screen of a television. CONSTITUTION:The luminescent line signal is possessed by fitting a photosensor 2 to one part of the screen of the television as the object of measurement, and a video signal is possessed from a tuner 14 to be tuned independently of the television as the object of measurement.

Then, the channels of the tuner 14 are successively switched until the both results of the judgement are made positive, and the channel in the case of having the positive results is specified as the viewing channel of the television as the object of measurement. Thus, the television viewing channel can exactly be specified regardless of the using form or the type of the television.

Title: Prevention method of decarburization of steel product
Inventor: NAKAMURA MOTOHARU
IPC: C21D1/70
Filed: 1979-11-14
Abstract: PURPOSE:To make it possible to completely prevent decarburization of the surface of steel products to be hot-rolled when the steel product is hot-rolled at a heating furnace in the atmosphere, by applying a sulfur-containing chemical agent on the surface of steel product surface to be hot- rolled and further, an antioxidant thereon. CONSTITUTION:When a steel product to be hot-rolled, such as high carbon steel billet containing >=0.6% C, is heated in a heating furnace in the atmosphere, the following pretreatment is made on the surface of steel product to be hot-rolled before the steel product is put into the heating furnace. That is to say, on the surface of steel product to be hot-rolled, a chemical agent containing organic substance or inorganic substance containing sulfur, especially thiourea and any other substance similar to this or any thiourea derivative, is applied to form one layer or more and, after that, layer or more of an antioxidant is formed on the layer of chemical agent. The steel product is heated in the atmophere. As the result, the coating layer of sulfur-containing compound is effectively isolated from the air by the layer of antioxidant, and the part between the layer of antioxidant and base iron in the heating furnace is maintained under a sulfide atmosphere and a dense film of sulfide is formed on the surface of steel product. Therefore, decarburization of billet surface is prevented and occurrence of primary scale in the heating furnace is also prevented.
