IPC: B21B13/02
Filed: 1989-06-16
Abstract: PURPOSE:To miniaturize equipment and to save its space by making the housing stanchions of the outlet side of a front rolling mill and the housing stanchions of the inlet side of a rear rolling mill of adjacent two rolling mills share one housing stanchion and integrating the housings of the above two rolling mills. CONSTITUTION:The housing 1 of rolling mill consists of four housing stanchions 1a, etc., and upper and lower housing beams 2, 3.

Title: Kerosene oil burning device
Inventor: SUZUKI JIROU
IPC: F23D3/08
Filed: 1978-12-12
Abstract: PURPOSE: To provide a kerosene oil burning device, free from an ill effect occurring due to tar,  being constituted wherein the results of burning a fuel-soaked wick can be effectively available in  the case of the intermittent use and an evaporation wick can be replaced easily when the combustion deteriorates due to the continued use.  
     CONSTITUTION: Fuel is fed to a fuel chamber 12, and air, simultaneously is supplied to a primary  combustion chamber 15 and a secondary combustion chamber 17. When an ignition heater 18 is  heated thereupon, fuel soaked by an evaporation wick 11 is evaporated for ignition. A part of  evaporated gas is burned in an evaporation hole 14, an evaporating unit 13 being maintained at a  given temperature, i.e., at lower than a boiling point temperature. Evaporated gas not burned in  the primary combustion chamber 15 is burned in the secondary combustion chamber 17. Since air  flowing in through the evaporation hole 14 carries upward evaporated gas on the surface of the  evaporating unit 13, the said air has an air-follow property the fluctuates an evaporating volume  to the air volume fed to the evaporating hole 14, and air volume fed to a secondary air hole 16  also fluctuates to the air volume flowed to the evaporating hole 14. This prevents change in an air- fuel ratio. Where extinguishing is performed by burning a fuel-soaked wick before a device stops  burning due to the tar adhesion, it allows a tar receiving unit 20 to be heated to a high temperature, and causes burning-out of the tar piled therein.

Title: Measurement of characteristics of epitaxial semiconductor wafer
Inventor: WAKE MITSUYASU
IPC: G01R27/02
Filed: 1996-06-14
Abstract: PROBLEM TO BE SOLVED: To make it possible to take directly a high-accuracy measurement of a resistance to a substrate wafer by current conduction in an epitaxial layer, by a method wherein a buried diffused layer of a conductivity type different from that of the epitaxial layer is made to interpose between the semiconductor substrate and the epitaxial layer to prevent a measurement current from leaking to the side of the substrate. SOLUTION: A buried layer 3 consisting of a P-type diffused layer is formed between a substrate wafer 1 and an N-type epitaxial layer 2. The probes 5 to 8 of a four-probe method measuring device 4 with four proves 5 to 8 arranged at equal intervals on a straight line are applied to the surface of the layer 2 over the layer 3 to measure the resistance of the wafer 1. That is, a constant current is made to flow through the probes 5 and 8, a voltage between the probes 6 and 7 is measured and the specific resistance of the layer 2 is found by an arithmetic expression from the measured value of the voltage. Accordingly, as a measurement current is prevented from flowing out to the side of the wafer 1 by the layer 3 and is made to flow through the surface layer of the layer 2, the specific resistance of the layer 2 itself can be measured with high accuracy.

Abstract: PURPOSE:To increase the utilization efficiency of a luminous flux and to realize a compact size of the width of a front lens by composing both lateral ends of a concave mirror in a rotary paraboloidal form and the central part in a parabolic form in the vertical section. CONSTITUTION:The left side and the right side zones of a reflector 7 are composed in a rotary paraboloidal form. The central part is also composed in a parabolic form in its vertical section. As a result, the reflected light is made into a horizontal parallel luminous flux in the vertical section. When points a0 and a0' to f0 and f0' are taken from both ends to the center, the points b0 and b0' are on the borders between the both side zones and the central zone. The points a0 and a0' are positioned on the rotary paraboloid. As a result, the reflected lights at the points a0 and a0' are made parallel to the optical axis Z-Z. The diffused reflected light is radiated to the front side as a diffused luminous flux to form a desired light distribution pattern. Consequently, the utilization efficiency of the luminous flux is increased, and the size of the width of a front side lens can be reduced.
