Title: Fine displacement measuring unit using discharge tube
Inventor: INOUE KIYOSHI
IPC: G01B7/00
Filed: 1978-12-28
Abstract: PURPOSE: To enable to measure the fine displacement of gap with high accuracy, by avoiding the error due to temperature difference through the addition of the circuit compensating the temperature change with the detection signal circuit of discharge tube.  
     CONSTITUTION: The internal impedance circuit of the discharge tube 1 consists of the electrodes 3, 31, 4, differential amplifier 8 and power supply 7. Since the discharge tube 1 is excited via the measured gap 5, the gap detection signal is changed with external temperature. To compensate the temperature, the circuit consisting of resistor 71 and transistor 10 is provided, the circuit current is increased when the temperature increases, and the signal current detected with the resistor 71 is increased. Since back bias is fed to the differential amplifier 8, the detection signal is reduced and compensated. Conversely, in case of temperature decrease, the bias signal is reduced. Thus, by performing the compensation due to temperature change, fine displacement can be measured with high accuracy.

Inventor: KAIZU SUSUMU
IPC: B23K26/00
Filed: 1994-07-14
Abstract: PURPOSE:To reduce the generations of blowhole and undercut, and to dilute carbon penetrating into a molten metal by performing laser welding while supplying a filler wire to a part irradiated by a laser beam. CONSTITUTION:While supplying a filler wire 13 to the butted part 4 of resin composite damping steel sheets 1 and 2 with a resin layer 3, butt welding is performed by irradiating the butted part 4 with a laser beam 12. The filler wire 13 must be a nonferrous metal with no carbon contained essentially. Or, the filler wire 13 must be an austenitic stainless steel or a ferritic stainless steel. Air bubbles are incorporated from the resin layer 3 into a molten metal, and air gaps are generated. However, the air gaps are filled by the melted filler wire 13, and the molten metals blown out at the time of the generation of the air bubbles are filled up. Carbon is penetrated from the resin layer 3 into the molten metal, however, a rise in the carbon quantity of the steel of a weld zone is suppressed by the filler wire 13 with low carbon, and the hardening of the weld zone is reduced.

Title: Vertical type rapid melting furnace
Inventor: KAWANO YUTAKA
IPC: F27B1/16
Filed: 1994-06-10
Abstract: PURPOSE:To stimulate a rapid combustion reaction of cokes to melt a raw metal in a high temperature and strong reductive atmosphere by a method wherein two or more vertically-long tuyeres having a specified height to width ratio are provided to feed pressurized air mixture having a specified oxygen concentration into a melting zone just above a molten metal retention zone and form a high-temperature zone with a low-height melting zone and a reductive zone. CONSTITUTION:Two or mor tuyeres, which are vertically-long and have a height (1) larger than the width (d) and a height (1) to width (d) ratio ranging from 1:3 to 1:8 and through which air mixture with an oxygen concentration of 28-60% is supplied, are provided so that a rapid combustion reaction of cokes is stimulated and the height of a high-temperature zone can be increased. As the vertically-long tuyeres have the height (1) to width (d) ratio of 1:3-1:8, a super-high temperature zone just before the tuyeres cant be kept high enough. Thus, the super-high temperature zone just. before the tuyeres and generation of carbon monoxides cause an abrupt endothermic reaction with cokes located at the upper parts of the tuyeres. Therefore, a furnace has a high- temperature melting mechanism with a very narrow high-temperature melting zone and a strong reductive atmosphere of carbon monoxide, and a rapid melting occurs due to direct contact with reaction heat and high-temperature gas.
