Title: Ceramic fixed resistor
Inventor: KAYAMA TAKASHI
IPC: H01C7/00
Filed: 1992-09-19
Abstract: PURPOSE:To obtain a ceramic fixed resistor which is durable, has a wide range of resistance values, and can be manufactured without using a non-oxidizable atmospheric furnace at the time of baking, by specifying the compound ratio, this ceramic fixed resistor comprising a ceramic insulating material, a conductive material and an additive. CONSTITUTION:By compounding in a wide rage 0.1wt.% to 85wt.% of ceramic insulating material composed of MgO and SiO2 with 15wt.% to 99.998wt.% of conductive material composed of SnO2, ZnO and Sb2O3, a solid resistor having a wide range of resistance values in the order of 10<-1>OMEGAcm to 10<7>OMEGAcm can be obtained from the same material. Further, by adding as an additive 0.1 to 20mol% of at least one of CaO, SrO and BaO, the baking temperature can be reduced, thereby enabling a resistor having a wide range of compound ratio to be baked at a practical temperature. Accordingly, the high-voltage pulse and high-current pulse characteristics are improved and the resistance value change rate can be lowered, and reduction of the raw material is achieved because part of SnO2 is substituted for by ZnO.

Title: Pneumatic tire
Inventor: INOUE TAKUMI
IPC: B60C15/06
Filed: 1998-10-15
Abstract: PROBLEM TO BE SOLVED: To provide a pneumatic tire capable of extending a life of a bead part by suppressing generation of separation. SOLUTION: Since the end 16C of a carcass ply 16 is not arranged in a part well movable at internal pressure charge time and at rolling time even in a bead part 11, generation of separation with the end 16C serving as a core can be suppressed. Since a radius of curvature R of a curved part 16Bc is ensured by 5 mm or more by arranging a first rubber 18 in a region surrounded by a first part 16Ba, curved part 16Bc, and a second part 16Bb, separation of the carcass ply 16 and the rubber in the periphery bonded thereto can be prevented by suppressing interlayer shear strain between the first/second parts 16Ba, 16Bb, and a break of a cord in the carcass ply 16 can be prevented by eliminating concentration of stress.

IPC: H05B41/24
Filed: 1991-08-21
Abstract: PURPOSE:To make stable supply of electric power to a discharge lamp and reduce power loss by supplying power to the lamp from an AC power supply which is an inverter emitting the variable frequency output. CONSTITUTION:When a gate input is impressed on a semiconductor element 6 constituting a main circuit from a diode bridge 3 which works as a frequency control circuit, an AC output voltage is immediately generated at the output terminal of an inverter 6. At the same time, a discharge starting resonance circuit is actuated, and discharge starting high voltage pulses are impressed on a discharge lamp 9, and electric discharging is commenced. At the same time as current feeding to the discharge lamp 9, the amperage value is passed through a current sensing CT 11 for adjustment of the output frequency of frequency control circuit 10, which generates the operation that the effective value of discharge current is maintained always at a constant value. That is, the output frequency is raised while the internal impedance of the discharge lamp remains low, and associate therewith the reactor value of a stabilizing reactor 7 is heightened. When electric discharge approaches the stable state, the output frequency is lowered.

Title: Automatic exposure controller
Inventor: GOSHIMA YUKIE
IPC: H04N5/235
Filed: 1991-11-11
Abstract: PURPOSE:To improve the picture quality in a back light state by detecting the output signal levels of the center and peripheral areas of an imaging element and controlling the diaphragm which controls the incident light of the imaging element in accordance with the difference of detected signal levels. CONSTITUTION:The maximum difference value Ymax of signal levels obtained in a back light state detected by a full screen contrast detecting part 17 is inputted to a weight control part 18. The part 18 calculates the weights Gc and Go of a subject area Ec and a background area Eo respectively based on the detecting result of the part 17. These calculated weights are multiplied by the outputs of the level detecting parts 10 and 11 of both areas Ec and Eo respectively by a multiplier 22. Thus the weighted levels are obtained. An arithmetic part 19 adds both weighted levels together to calculates the weighted average value Y (=Ec*Gc+Eo*Go). This value Y is outputted to diaphragm control circuit 9. Thus the circuit 9 controls the diaphragm in accordance with the value Y so as to keep this value Y at a prescribed target level.

Abstract: PROBLEM TO BE SOLVED: To obtain a silicon carbide molding having 8 specified bulk density and not causing the peeling of the surface layer by carbonizing a mixture of a thermosetting resin and an organic product in a liquid phase carbonization step and then carrying out silicification by a chemical vapor phase reaction. SOLUTION: A thermosetting resin having a high remaining rate of carbon, e.g. a phenolic resin is mixed with 10-50 wt.% organic product, e.g. mesocarbon microbeads or raw coke produced in the liquid phase carbonization of heavy petroleum oil or pitch. The mixture is molded hardened at about 200 deg.C, fired at a controlled heating rate and carbonized in an inert atmosphere at >=800 deg.C to form a substrate for conversion into silicon carbide. After the carbonization, high purification treatment such as heat treatment in the presence of gaseous halogen is carried out if necessary. The carbonaceous substrate is then allowed to react with gaseous SiO to obtain the objective silicon carbide substrate having 2.4-2.8 g/cm3 bulk density.  Since this substrate has no warpage and is excellent in dimensional stability, it is suitable for use as a dummy wafer used in a step for heat-treating semiconductor wafers.
