Abstract: PURPOSE: To join a pyrolytic graphite member and a metal member by brazing without causing cracking in a pyrolytic graphite member by arranging a graphite member reinforced with carbon fibers in parallel between the pyrolytic graphite member and the metal member, and joining the graphite member reinforced with carbon fibers by brazing.  
     CONSTITUTION: In joining the member consisting of the pyrolytic graphite and the metal member by brazing, both members are not soldered directly to each other, but by way of the intermediately arranging a member consisting of the graphite reinforced with carbon fibers. Further, at this time, the pyrolytic graphite and the carbon- fiber reinforced graphite are positioned in relation to each other in such a way that the stratification of pyrolytic graphite runs approximately parallel to the primary orientation plane of carbon fibers within the carbon-fiber reinforced graphite. Further, the brazing is preferably executed with an alloy foil of 70 wt.% silver, 27 wt.% cupper and 3 wt.% titanium arranged between both members in a vacuum at about 850°C. As a result, the pyrolytic graphite and the carbon-fiber reinforced graphite are aligned in the priority direction of the thermal conductivity and coefft. of thermal expansion, thereby good joining by brazing is achieved without causing cracking in the pyrolytic graphite.

Title: Radio receiver having radio data signal decoder
Inventor: YURUGEN KETSUSAA
IPC: H04H20/00
Filed: 1991-08-01
Abstract: PURPOSE: To directly switch the radio receiver to a transmitting station having the highest probability of fine reception by correspondingly arranging learnt memory in each substitution frequency memory. CONSTITUTION: When received quality or the carrier frequency set up by a channel key 10 drops from a prescribed threshold while driving, a microprocessor in an automatic channel selection device receives a start instruction of a program for setting up substitution frequency. The program starts the setting of one of plural substitution frequency bands at random in a substitution frequency memory 13. At the time, the direction of setting is given through leant memory 14. The memory 14 is empty at first, and when the received quality drops from the prescribed threshold after newly operating the channel key 10, one of other substitutive frequency bands is accessed at random, and at the time of detecting substitution frequency having fine received quality, the detected frequency is recorded in the memory 14.  Consequently the radio receiver can be directly switched to a transmitting station having the highest probability of fine reception.

Filed: 1992-06-26
Abstract: PURPOSE:To eliminate an isolated point without deteriorating image quality in an image processing device equipped with a circuit to eliminate a point (noise, etc.) that exists by being isolated from an original image. CONSTITUTION:A window centering a remarked pixel is formed by line memory 1-4 together with a latch circuit 5. It is decided whether or not the remarked pixel is the isolated point by using the value of the pixel forming the window by an isolated point decision circuit 6. When the isolated point is eliminated by substituting another data by an isolated point elimination cirucit 7, data with less incongruity with the peripheral base color of the remarked pixel are prepared as data to be substituted. As such data, data of base color level, the maximum value, the minimum value, the mean value, or an intermediate value, etc., of the base color pixel of the window to which the remarked pixel belongs can be used. The image quality can be prevented from being deteriorated even when the isolated point is eliminated by substituting the above mentioned data for the data of isolated point.

Title: Manufacture of thick steel plate having uniform material characteristic in plate-thickness direction
Inventor: TSUZUKI TAKESHI
IPC: C21D8/02
Filed: 1986-08-19
Abstract: PURPOSE:To obtain a thick steel plate having material characteristics of microstructure and mechanical properties homogeneous in the direction of plate thickness even after control rolling, by subjecting a carbon steel or low alloy steel slab to cooling or to cooling after rolling to a slight extent and then by applying reheating to the above prior to control rolling so as to make the whole slab low-temp. and also to uniformize the temp. CONSTITUTION:The above slab is heated to a temp. between the Ac3 point and 1,150 deg.C, which is cooled after rolling to a thickness of intermediate stage or in the state of a slab without application of rolling. The cooling is stopped before the temp. in the center of plate thickness comes down to a temp. lower than the Ac3 point, followed by reheating. That is, at the point of time when the above cooling is stopped, there is a case where the temp. at the surface falls below the Ar3 point and also a case where, although the surface temp. does not fall below the Ar3 point, considerable temp. difference is observed in the center, and so the surface is subjected to heating and temp. raise to a temp. level where the above temp. difference can be removed and uniformization of the temp. in the direction of plate thickness at the time of rolling can be attained. Then rolling is carried out at a temp. of Ar3 point or above at 30-70% draft. In this way, the difference in material characteristics in the direc tion of plate thickness of a thick steel plate can be reduced.
