IPC: H01F41/02
Filed: 1991-06-04
Abstract: PURPOSE:To produce the high-performance magnet by subjecting alloys specified in phase compsn. to press molding and sintering, then to an aging heat treatment. CONSTITUTION:An alloy mainly consisting of an R2Fc14 phase is used for the alloy A and an alloy contg. R, Co, Fc, B and Ga and consisting of an R2T<1>14 phase and/or R rich phase and a phase mixture composed of one or >=2 kinds among RT24L phase, RT<2>3 phase, RT<2>2 phase and R2T<2>7 phase is used for the alloy B. The alloy B powder is mixed at 1 to 30wt.% with 99 to 70wt.% alloy A powder and the alloy mixture powder is press molded in a magnetic field. The molding is sintered in a vacuum or inert gaseous atmosphere and is then subjected to the aging heat treatment at the sintering temp. or below. As a result, the high-performance magnet having high coercive force, high residual magnetic flux density and high energy product is produced by effectively utilizing the costly additive elements.

Title: Cold forging method for inner spline having teeth chamfering
Inventor: HIRATA YASUO
IPC: F16D1/02
Filed: 1988-06-28
Abstract: PURPOSE:To continuously conduct forming for an inner spline and chamfering for a tooth surface by providing a chamfering part at a position where forming by a spline extruding die is finished and arranging a knockout sleeve keeping concentric state with the spline extruding die. CONSTITUTION:Since a blank 1 is pressed against the tooth profile part 2b of a die 3 and a mandrel 2, material flows into a void part 2d of the mandrel 2 to form an inner spline. When a punch 5 is lowered, further, the material flows along a chamfering part 2c arranged so as to agree with the center of the void part of the mandrel 2 to form a chamfered shape at the tip of the spline but a void part 1e is found on the chamfered ridge part at this time. When the punch 5 is lowered furthermore, the material of the blank 1 is controlled by the knockout sleeve 4, flows into the void part 1e to form a sharp chamfered ridge. In this way, a chamfering stage can be removed because the spline forming part and the teeth chamfering part are provided continuously.

Title: Coding device
Inventor: ETOU YOSHIZUMI
IPC: H04N7/24
Filed: 1982-09-17
Abstract: PURPOSE:To code efficiently the signal containing synchronizing signals and video signals of different levels like TV signals, by using such pattern that could not exist in the video signal. CONSTITUTION:The TV signal applied to an input terminal 1 is converted into the prescribed code by a coder 3 and applied to a switch circuit 4. On the other hand, the synchronizing signal is separated through a synchronizing separating circuit 5 and the switch 4 is switched with the separated synchronizing signal. Then the synchronizing code which is obtained from a synchronizing code generator 6 is selected for a synchronizing period of the TV signal. Thus the output code given from the switch 4 is applied to an input terminal 7 of a decoder through the processes such as the transmission, recording, etc. The received signal is decoded by a decoder 8 in a decording device and applied to a switch 9. In this case, the area of the synchronizing signal is coded with a level that could not exist actually. Therefore the level of a correct synchronizing signal is not decoded. As a result, the synchronizing code is detected out of the received input signal by a synchronizing code detector 10.

Abstract: PROBLEM TO BE SOLVED: To prevent dew condensation on the surface of a lens by constituting a lens frame of material having large heat conductivity and providing an extension area part for heat exchange from the lens frame to a space part between lenses. SOLUTION: The 2nd lens frame 5 is constituted of the material having the large heat conductivity, for example, aluminum, copper or silver.

Plural annular grooves 5a are formed as the extension area part for heat exchange facing to a front space part on the front end face of the frame 5, and their surfaces are formed to be rugged so as to function as a projection part for heat absorption. As for the shape of the projection part for heat absorption as the extension area part for heat exchange, it is important to make surface area as large as possible to such an extent that it does not interfere in other lens barrel parts. By making the surface area large, heat transfer between the space part between a 1st lens group L1 and a 2nd lens group L2 and the frame 5 is improved.
