Title: Range finder
Inventor: HARADA OSAMU
IPC: G01C3/06
Filed: 1995-03-15
Abstract: PURPOSE: To prevent erroneous range-finding due to Schotkey noise by switching a limitless judgement level based on luminance information from a luminance measuring means and setting the limitless judgement level to higher level, when a range-finding target is positioned in a infinite distance and the luminance is higher than the prescribed value. CONSTITUTION: A signal 4 for a control circuit opens/closes a switch 127 by intensity of luminous of an object to a prescribed value of a light measurement result and reference voltages of a comparator 123 are set to V2 ', V2 or high/low respectively. When an infrared LED light falls on a semiconductor position detector 101, signal currents IA, IB flow. When LED emits, outputs of operation amplifiers 105, 112 lower.rise so that the output of an operation amplifier 108 rises/lowers. Therefore, when the signals 2, 3 of a controller reach a H level in switching LED off, a capacitor 121 is integrated in the rising direction so that the signal 5 is judged to be limitless compared with the reference voltage by the comparator 123.  When the signal 5 is a L level, the capacitor 121 is integrated in the inverse direction and the control circuit finds the distance from the time when the signal voltage V0 reaches the constant voltage VC.

Filed: 1989-03-31
Abstract: PURPOSE:To form a steep temperature gradient along the scanning direction of a laser beam on a specimen to enable the coagulation of crystals in one direction by disposing a compulsorily cooled portion in proximity to a laser beam-irradiated portion when a long size material comprising an oxide superconductor substance is continuously irradiated with the laser beam to crystallize the material. CONSTITUTION:A laser beam 3 is approximately rectangularly irradiated on a long size material comprising an oxide superconductor substance or a material giving a superconductor by the melting.coagulation thereof, e.g. a thin film 1 formed on a long size substrate 2 and simultaneously scanned in the direction of the arrow to heat and melt an irradiated portion 1a, followed by cooling the melted portion from the backward direction with the movement of the laser beam to recrystallize the melted portion. A compulsorily cooled region is disposed just behind the laser beam- irradiated portion 1a, and liquid nitrogen, etc., is sprayed, immersed, etc., to cool the melted portion, thereby increasing the crystallization of the material in a state wherein the temperature gradient of the thin film 1 is enlarged in the scanning direction of the laser beam. A laser beam having a belt-like pattern is subsequently repeatedly irradiated on the treated portion at a relatively low temperature in a high oxygen pressure atmosphere or in an oxygen stream to anneal the treated portion.

Title: Method for charging raw material to blast furnace
Inventor: YAMAMOTO RYOJI
IPC: C21B5/00
Filed: 1985-04-19
Abstract: PURPOSE:To improve the air permeability and gas distribution condition in a blast furnace to decrease a coke ratio and to improve productivity by forming an ore layer in the raw material layer in the blast furnace in such a manner as to consist the same of a mixed layer composed of ore and coke. CONSTITUTION:The ore (a) and the coke (b) are preliminarily laminated into a hopper 3 for feeding the ore so that the ore layer in the blast furnace consists of the mixed layer 7 composed of the ore (a) and the coke (b) in the stage of charging the ore and coke into the blast furnace 1. Such mixed layer is carried by a conveyor 4 to the furnace top from which the layer is charged alternately with the coke layer 6 in the laminar state into the furnace. Since the coke is uniformly dispersed in the ore layer, the permeation distributing characteristic of the ascending gas in the raw material layer, particularly the ore layer in the furnace is improved without hindering the permeability of the reactive gas in the softening and melting zone of the ore in the lower part of the blast furnace. As a result, the furnace condition is stabilized and the effect of decreasing the content of Si in the molten iron, decreasing the coke ratio and improving the productivity of the furnace is obtd.

Abstract: PURPOSE:To prevent edge short failure due to floating die pad, and function failure of semiconductor circuit elements due to stress generated at the time of resin contraction caused by heat and moisture after molding, in the molding process of a semiconductor device assembling process. CONSTITUTION:A semiconductor circuit element 7 is mounted on a semiconductor circuit element fixing part 3 of a lead frame 1 for a semiconductor device, and a stress relaxing plate 23 is mounted on the opposite surface.
