Title: Imaging device
Inventor: TSUDA YUJI
IPC: H04N5/378
Filed: 1996-12-16
Abstract: PROBLEM TO BE SOLVED: To improve the definition of a video image by providing an OB integrated value detecting means for integrating and detecting an optical black level(OB level), and an OB integration control means for making the OB integrated value be ineffective in a fixed period. SOLUTION: A picture signal detected by a CCD 1 is sample-held by an S/H circuit and an AGC circuit 2 to be amplified into a prescribed level, and its DC component is cut by a coupling capacitor. Then, the resulting signal is clamped at the timing of the clamp pulse generated in a clamp pulse generating circuit 6 by a voltage generated in a DC voltage generating circuit 9 by a clamp circuit 3. The clamp pulse is supplied to the OB integration control circuit 7 on the other hand. In the OB integration control circuit 7, the edges of rising and falling of the clamp pulse are detected respectively, a control signal is generated in the period before and after, and is transmitted to an OB level correcting circuit 8. The OB level correcting circuit 8 receives the output of the OB integration control circuit 7, and stops OB level integration during the control signal is generated.

Abstract: PURPOSE:To produce alloy powder for a bond magnet improved in magnetic properties, by sticking and forming on alloy powder of an R2Fe14B phase (R denotes rate earth element including Y) contg. a specified amt. of Co, a liquid phase compound layer contg. R more than the alloy powder. CONSTITUTION:Main component series alloy powder or an R2Fe14 B phase main phase essentially consisting of, by atom, 12 to 25% R, 4 to 10% B, 0.1 to 10% Co and 68 to 80% Fe and liquid phase comound powder constituted of 20 to 45% R, 3 to 20% Co and <=12% B, and the balance Fe are blended and mixed. The liquid phase compounds are ones in which an R2(FeCo)14B phase is partially contained in an intermetallic compound phase of Co or Fe and R contg. an R3Co phase. By this blending and mixing, the liquid phase compound powder is stuck on the surface of the main component alloy powder grains, and, if required, coating treatment is applied. Next, these are subjected to heat treatment at 700 to 1050 deg.C. In this way, the liquid phase compound layer is stuck and formed on the surface of the main component alloy powder, by which the falling of boundary layers at the time of fine pulverizing and surface defects are recovered to improve its magnetic properties.

Filed: 1988-12-29
Abstract: PURPOSE:To separately set an unreadable/unwritable sector, a read-only sector and a readable/writable sector by determining the possibility/impossibility of access to a data part by a comparing means. CONSTITUTION:A microprocessor circuit 30 outputs a seek instruction to an instructed cylinder, and when seeking operation is completed, the microprocessor circuit 30 reads data from the address of a main storage device 500, a SYNC byte and a CRC are added by a magnetic disk control circuit 20, and the data are written and formatted as an ID part to the magnetic disk device 200 with the data from the main storage part 500 as a FLAG byte, a sealing number, a track number and a sector number. In such a case, a value (a) is written when read/write is always permitted as the value of the FLAG byte, a value (b) is written when only read is permitted in a normal access level, and a value (c) is written when neither read nor write is permitted in the normal access level. Thus the sector which can be read only by a specific high-order device can be separately set.

Title: Rolling bearing
Inventor: MATSUMOTO YOICHI
IPC: C21D9/40
Filed: 1989-12-25
Abstract: PURPOSE:To lengthen the life time of a rolling bearing by forming a rolling element with an alloyed steel which is made in the range of hardness of HRC 62-70 by way of high temperature tempering and is less than 12mum of carbide in size in the roundness conversion diameter. CONSTITUTION:A rolling bearing consisting of a bearing ring and a rolling element is obtained by sintering an alloyed steel powder which is in the range of hardness of HRC 62-70 and is less than 12mum of carbide in size in the roundness conversion diameter by way of 450-600 deg.C high temperature tempering. And the hardness of the rolling element is made more than the hardness of the bearing ring. By way of carrying out hardening heat treatment (quenching, high temperature tempering), retained austenite is changed to martensite and simultaneously carbide is deposited in matrix and hardened. Consequently, a change of measurement is prevented and the measurement stability in a high temperature environment is improved. Additionally, this carbide is hard and excellent in abrasion resistance, and consequently, rolling fatigue resistance of the bearing is improved. Additionally, if carbide is fine, stress concentration due to overload is not caused, and accordingly the life time of the bearing is improved.

CONSTITUTION:Rigid urethane foam whose surface is molded and worked into an acute uneven curved surface is utilized as a forming mold 1. A decorative sheet 2 is closely stuck on the surface of the forming mold 1 by performing suction from the rear surface of this forming mold 1 by operation of a vacuum pump 4. In this state, soft urethane resin composition having five times of theoretical expansion ratio is injected on the surface of the decorative sheet 2 as expandable curing type resin 5. Platelike load 7 is imparted via kraft paper of a reinforcement sheet 6 and thereby the foam 5 is formed and cured. Thereafter the load 7 is removed and the composite decorative material in which the decorative sheet 2, the foam 5 and the rear reinforcement sheet 6 are integrated is detached from the forming mold 1. Thereby the composite decorative material is obtained wherein the acute and fine uneven surface of the forming mold is accurately transferred and shaped.

Inventor: TOYOSHIMA TOSHIYA
IPC: H01L33/30
Filed: 1993-12-28
Abstract: PURPOSE:To obtain a uniform semiconductor light emitting element having high luminance with high reproducibility by specifying Si concentration in a p-type GaAs substrate. CONSTITUTION:Since a quartz boat (SiO2) is, when a Zn-doped GaAs single crystal is formed by a boat growing method, used, Si is always mixed with the crystal.

Title: Apparatus for measuring temperature of molten metal
Inventor: YAMADA YOSHIRO
IPC: G01K1/08
Filed: 1996-12-17
Abstract: PROBLEM TO BE SOLVED: To enable a sufficient length of an optical fiber to sink in a high-speed molten metal flow and measure a temperature highly accurately, by coating the optical fiber with three layers of a metallic protecting tube, an insulating material and a metallic protecting tube sequentially from the inner side. SOLUTION: A metallic protecting tube (inner tube) 2 is set in the outer circumference of an optical fiber 1, and an insulating material 3 and a metallic protecting tube (outer tube) 4 are further provided in the outer circumference sequentially. The optical fiber 1 coated with three layers is inserted at right angles to a molten metal flow 5 at a predetermined speed. At this time, even when a leading end sinks, the outer tube 4 has a large diameter and high rigidity and therefore the leading end is kept in an insertion attitude. However, the insulating material 3 is melted and exposed instantaneously when the leading end touches the molten metal flow because a melting point is lower than a temperature of the molten metal flow.  Meanwhile, the insulating material 3 contains an additive of a higher melting point than the temperature of the molten flow, e.g. carbon particles and, the carbon particles are carbonized in a state without oxygen. As a result, the inner tube 2 is not melted immediately even under high temperatures and is melted after reaching the interior of a main stream of the molten flow 5. The optical fiber is exposed at this time and surrounded by the molten metal. A sufficient length of the optical fiber is let to sink in the molten flow in this manner.
