Patent JP-H1070714-A (JP)
Title: Image transmission system
Inventor: KOKURYO GARO
IPC: H04N19/00
Filed: 1996-08-26
Abstract: PROBLEM TO BE SOLVED: To reduce frame removal and to improve picture quality when there is no block error on a transmission line. SOLUTION: The image transmission system which resends image information when detecting an error occurring on the transmission line increases the generation speed of the image information and send more image information on condition that information sent from a reception side is correctly received information. Further, when an image compressing function is combined, the image compressibility is lowered and the picture quality is improved unless the need for resending is answered from the reception side. Consequently, the frame removal rate decreases and the motion of a subject on the reception side becomes smooth when there is no error on the transmission line or when the error rate is low. Further, an image of good picture quality is obtained on the reception side when the image compressibility is lowered.

Abstract: PURPOSE:To absorb a deformation stress by means of a corrugated portion and to improve flexibility and sealing ability by using a gland packing GP formed by laminating expansion graphite sheets formed in a corrugated shape. CONSTITUTION:In the annular space of a mold formed with a dice mounted to a press, a core, and a lower punch the upper surface of which is plane, expansion graphite powder is first contained in the bottom part thereof, and a plurality of expansion graphite sheets (corrugated rings) 4 in a concentrically corrugated shape are laminated thereon. Expansion graphite powder is further placed thereon, and a contained substance is pressurization-molded for integral formation by means of upper and lower punches the upper surfaces of which are plane to produce a desired gland packing GP. The section of the ring of the GP is formed such that the upper and lower parts of the corrugated ring 4 are nipped between expansion graphite molded products 5 the one side of each of which is corrugated. As a result, even when the GP is twisted during insertion of it externally of a valve rod, a deformation stress is absorbed by means of a corrugated part, and layer-to-layer peeling and a breakage are prevented from occurring.

Title: Video signal clamping circuit
Inventor: TANAKA SEIICHI
IPC: H04N5/92
Filed: 1987-09-08
Abstract: PURPOSE:To stably and accurately clamp a video signal, by constituting the titled circuit so that a detected level error of a digital video signal is offset. CONSTITUTION:A video signal is clamped once by a clamping circuit 3 before converting it by an A/D converter 4, and after the A/D conversion, the level of the part (a part of a specific synchronizing chip or pedestal) to be attention of a digital video signal is compared with a desired clamping level, then thus obtained level error is subtracted from a digital video signal on order to offset level error, and a clamping action is achieved again. Since the DC level of an input video signal is thus aligned by clamping prior to the A/D conversion, the dynamic range of the A/D converter can be effectively utilized. Also, by re-clamping in the part of digital processing, influences of the variation among elements, secular change, or thermal variation are eliminated, hence a video signal can be stably and accurately clamped.

Title: Opened yarn woven fabric
Inventor: KAWABE KAZUMASA
IPC: D03D41/00
Filed: 1999-08-06
Abstract: PROBLEM TO BE SOLVED: To obtain an opened yarn woven fabric excellent in resin impregnating properties and surface smoothness. SOLUTION: This opened yarn woven fabric is obtained by directly using a beltlike fibrous bundle T presubjected to an opening treatment and having a sufficiently nearly uniform width relatively to the thickness as a warp yarn and a weft yarn. The fibrous bundle T is sufficiently opened even in each crossing part of the warp yarn with the weft yarn and excellent in impregnating properties of a resin, scarcely causes the bending of the fiber bundle T in the crossing part and is reduced in stress concentration in the bent part. Thereby, the best use of mechanical characteristics of the fibrous bundle T can sufficiently be made to remarkably improve the surface smoothness of the woven fabric.

Abstract: PURPOSE: To enable the mount to have damping function in a range of wide- band frequency by providing, inside an overflow conduit having a substantially rectangular cross section, at least one web-like intermediate wall extending in the circumferential direction and vertically over a portion of the height of the conduit. CONSTITUTION: A working chamber 1 and a compensating chamber 7 hydraulically communicate with each other via a circular-annular overflow conduit 12. The overflow conduit 12 is formed by cutting the thick portion of a housing 9 with an intermediate wall 13 extending over a portion of the height of the conduit 12 remaining in the center. This means that the overflow conduit 12 having a substantially rectangular cross section is divided into two partial conduits 14, 15 by the intermediate wall 13. Under such circumstances, the intermediate wall 13 has a height in correspondence with the conditions in such a case. The wall friction area of the overflow conduit 12 with respect to liquid is increased by the intermediate wall 13, and damping is realized in a very wide band frequency range.
