Title: Punch for tube expansion
Inventor: KOJIMA TAKAO
IPC: B21D41/02
Filed: 1987-01-26
Abstract: PURPOSE:To improve the workability by an action of a relief of a back tapered part in the case of executing a tube expansion extending over a range where length is comparatively large against the diameter of a tubular body, by providing the back tapered part in the rear of a working part of the tip side of a punch. CONSTITUTION:In the vicinity of the tip of a tube expanding punch 10, a working part 16 of the outside surface, having the same diameter and being parallel is provided next a tapered part 12 which becomes a guide, and a chamfer part 14, and in its rear, a back tapered part 18 whose diameter becomes thin gradually is provided. At the time of a tube expanding work, an excess thickness is apt to escape to the small diameter side along the back tapered part 18, therefore, even if the capacity of a working machine is small, working can be executed. Also, galling to the punch 10, of a work which is being formed can be prevented. Moreover, due to existence of the back tapered part 18, at the time of drawing out the punch, it can be drawn out easily, and the accuracy of a product can also be improved.

Title: Mounting structure of suspension coil receiver in vehicle frame structure
Inventor: HAGIWARA YASUHISA
IPC: B62D21/00
Filed: 1996-01-31
Abstract: PROBLEM TO BE SOLVED: To facilitate the mounting and joining works of a coil spring receiver so as to prevent the occurrence of distortion by passing each cross member into each cross member through hole of the coil spring receiver and connecting the coil spring receiver with the cross member in a condition in which it is positioned. SOLUTION: Since a coil spring receiver 2 is provided with two cross member through holes 11 and a cross member 5 is passed into these through holes 11, the coil spring receiver 2 can sufficiently endure the action of external force in the vertical direction by a coil spring 14 and a damper 15 of a suspension 3 merely due to the structure. Consequently, the coil spring receiver 2 is connected in a condition in which it is positioned so that it is not displaced in the direction of length of the cross member 5. The coil spring receiver 2 may be connected to the cross member 5 lightly because external force which acts in the direction of length of the cross member 5 for the coil spring receiver 2 is small.

Title: Bidirectional visible ray data link
Inventor: ITOU TOSHIO
IPC: H04B10/2507
Filed: 1982-02-03
Abstract: PURPOSE:To obtain a transmitting/receiving module circuit suitable for the use of pairs of plastic optical fibers, by interposing a filter part between a transmitting part and a receiving part of a transmitting/receiving module. CONSTITUTION:An input electric signal 1 modulates the luminance of a light emitting element 10 and is converted to an optical signal. The transmitted optical signal is converted to an electric signal by a light receiving element 11 and is subjected to waveform shaping in a pulse reproducing circuit 12 and becomes an output electric signal. A modulating circuit for the input electric signal and a modulating circuit for the transmitted optical signal to the output signal 2 are separated from each other by a filter circuit 13 and are not affected by mutual signals. Thus, the crosstalk of bidirectional signals is prevented even if pairs of plastic optical fibers are used, and the transmitting/receiving module circuit using pairs of plastic optical fibers is completed.

IPC: H04N1/41
Filed: 1999-01-25
Abstract: PROBLEM TO BE SOLVED: To provide an image compression method by which compressed data to be reproduced even by a conventional decoder are generated at a high compression efficiency. SOLUTION: A pixel block 102 of a received image is classified into some types, based on analysis of each pixel value. Discrete cosine transform(DCT) 104F is applied to pixel values of the pixel block 102. A DCT coefficient obtained by the transform is given to a threshold processing and/or quantization processing 408F, based on each type classification of the pixel block by using a quantization correction process. In the case the coefficient is corrected and coded, the obtained data are decoded and inversely quantized in compliance with the JPEG (standard joint photographic experts group) sequential mode data syntax and an expression of the image with fidelity to perception is reproduced. In this case, information relating to the correction of the quantization is not required to be fed to the decoder.

Filed: 1997-01-30
Abstract: PROBLEM TO BE SOLVED: To prevent needless information on abnormality so as to prevent a user from being perplexed by informing abnormality only when a photographing control means controls an equipment in a 1st mode. SOLUTION: When a release switch is operated, photographing operation such as range-finding, photometry and exposure operation is performed, and a release switch is not operated, then a photographing lens is driven in a TELE direction when a telephotographic(TELE) switch 11(a) is operated. When the switch 11(a) is not operated and a wide angle(WIDE) switch 11(b) is operated, the photographing lens is driven in a WIDE direction. When the switch 11(b) is not operated, an EYE NG flag is confirmed. The EYE NG flag is a flag set when the line-of-sight detecting device is abnormal. In the case of EYE NG=1, it is judged that the line-of-sight detecting device is abnormal, and line-of-sight detecting operation is not performed. Thus, the release switch is accepted even when the line-of-sight detecting device is abnormal.
