Title: Sliding member for sealing
Inventor: YASUTOMI YOSHIYUKI
IPC: F16J9/28
Filed: 1987-08-20
Abstract: PURPOSE:To improve abrasion resistance, corrosion resistance, and heat and shock resistances by forming the surface of one of sliding faces with a ceramic consisting of SiC and a composite material of Si3N4 containing at least one of particles and whiskers thereof and forming voids. CONSTITUTION:The surface of one of seal members 5, 6 which are slidingly brought into contact with each other of a floating seal is formed with a ceramic consisting of SiC and at least one of the particles and whiskers of Si3N4, and voids, and the mother phases 1 of the SiC and the particles 2 of the Si3N4 are allowed to mixedly exist while the void 3 is formed to be approx. 20mum or less in diameter with a porosity of approx. 15%. And, the other sliding face is formed by use of a material, e.g., Al2O3, with a hardness lower than the hardness of the particle or whisker of the Si3N4. Thereby, abrasion resistance and corrosion resistance can be improved reducing the wear of the opposite material while increasing heat resistance and shock resistance.

Title: Convergence correction circuit
Inventor: IKEDA HIROYUKI
IPC: H04N9/28
Filed: 1993-08-20
Abstract: PURPOSE:To attain correct convergence correction even when a pattern size is hanged. CONSTITUTION:The circuit is provided with a horizontal pattern size detection circuit 60 rectifying a peak horizontal deflection current to detect the picture size and a vertical pattern size detection circuit 90 rectifying a peak vertical deflection current to detect the picture size and the amplitude of the convergence correction signal fed to convergence correction coils 20, 30 is controlled by the detection outputs. Since the amplitude of the convergence correction signal is controlled adaptively by the pattern size, convergence is corrected with a proper quantity based on the pattern size. Over-compensation of the convergence correction is avoided.

Further, the self-tuning of a standard value table A is performed as background processing with data of a past fault database.  Then the general logic calculates the probability of respective feature quantities by fault phenomena by using a standard value table A and a map B to find whole probability, which is compared, so that a fault phenomenon which is large in whole probability is displayed.

Title: Charge transfer device
Inventor: NABETA TERUYUKI
IPC: H04N5/341
Filed: 1987-08-20
Abstract: PURPOSE:To avoid a blooming, by overlapping a clear drain wiring extending in the channel longitudinal direction of a clear gate on a clear drain region, and extending the gate electrode of the clear gate so as to perpendicularly cross the wiring. CONSTITUTION:A clear drain wiring 22 extending in the channel longitudinal direction of a clear gate CHD is overlapped on a clear drain region 21, and the gate electrode 12 of the gate CHD is extended so as to perpendicularly cross the wiring 22. Since the channel width of the gate CHD is approached to the channel length of a potential well formed under the electrode 12 as near as possible, the channel resistance of the gate CHD can be suppressed to a low value to accelerate the discharging speed of the remaining charge of the well to flow through the gate CHD. Thus, an overflow is prevented to effectively avoid a blooming.

Title: Neutron carbon mirror and its manufacture
Inventor: KAWABATA YUJI
IPC: G01N23/202
Filed: 1999-07-22
Abstract: PROBLEM TO BE SOLVED: To provide a neutron mirror that can withstand stricter irradiation environment by polishing a carbon material containing graphite-retardant carbon being obtained by performing such treatment as burning to an organic resin material or the like to a specific surface roughness for manufacturing. SOLUTION: A neutron mirror with carbon as a material is manufactured, for example, by a furan resin. First, for example, a B stage film is created by a film-forming machine, the two films are laminated by a specific method for joining integrally, then are machined to an appropriate shape, and then are subjected to heating curing treatment. An obtained multilayered structure composition is, for example, subjected to carbonization treatment at approximately 1,400 deg.C in nitrogen atmosphere, and is further burnt at approximately 2,000 deg.C, thus obtaining a neutron carbon mirror material. By performing specific polishing machining treatment to the mirror material, a neutron carbon mirror whose surface roughness is for example approximately 0.64 nm is obtained.  The obtained mirror has a high neutron reflection factor and a large total reflection critical angle as shown in a figure and has less neutron absorption.

Title: Internal combustion engine tappet
Inventor: KANZAKI TATSUO
IPC: F01L1/20
Filed: 1997-08-01
Abstract: PROBLEM TO BE SOLVED: To prevent the separation of a cam receiving plate from occurring by applying the chamfer of the outer periphery edge of a cam receiving plate side so as to reach the tappet body in the tappet formed by joining an abrasion resistant metal-made cam receiving plate to the top wall of the tappet body. SOLUTION: A tappet body 1 of a cylinder shape having a top face blocked by a top wall 1a is formed of an aluminum alloy, and an abrasion resistant hard metal-made cam receiving plate 2 is fixed to the top face of the top wall 1a. Taper-like chamfers 5, 6 are applied to the up and down outer periphery edges of the tappet like this. As to the upper end chamfer 5, a design chamfer angle line is set so as to pass not only the cam receiving plate 2 but also the upper edge of the tappet body 1, and the chamfer is applied so as to reach the tappet body 1 along the angle line. Thereby, since force from a cylinder bore is received by the tappet body 1 even if the tappet inclines to the angle line, no application of shearing force to the cam receiving plate 2 is allowed so as to prevent the separation of the cam receiving plate 2.
