Title: Heat treatment of metallic product under protecting atmosphere
IPC: C21D1/74
Filed: 1991-03-22
Abstract: PURPOSE: To produce a steel strip and a steel wire excellent in the quality with the heat treatment in a short time by using scavenging gas containing high nitrogen content at the time of raising the temp. and introducing He mixed gas containing H at the cooling stage after heat treatment, at the time of executing the heat treatment to a coil of the steel strip, steel wire, etc., with a batch furnace.  
     CONSTITUTION: At the time of applying the heat treatment of annealing, etc., in the batch furnace to the coil of the steel strip and the steel wire, at the first temp. raising stage, N 2  gas is supplied into the batch furnace to purge the air, and further, N 2  gas containing 3-5% H 2  is introduced and the temp. in the furnace is raised to the annealing temp., and after holding for a prescribed time to execute the annealing, the temp. in the furnace comes to cooling stage. In this cooling stage, He gas containing ≤20% H 2  is introduced into the atmosphere in the furnace to discharge the annealing gas consisting essentially of N 2  to out of the furnace and the introducing of He gas containing H 2  is continued until He in the atmosphere in the furnace becomes ≥50% to execute the cooling. There is no fear of the explosion of H 2  gas, and the coil of the steel strip and the steel wire having the same high quality as in the case of annealing in the H 2  gas atmosphere can efficiently be annealed in extremely shorter time than the conventional N 2  gas atmosphere furnace.

Abstract: PROBLEM TO BE SOLVED: To make it possible to easily specify an interrupted switching element, by providing a signal generator for generating a signal for specifying the interrupted element connected to a plurality of semiconductor switching elements, and a display unit for displaying the interrupted element by visual information. SOLUTION: When any one IC 12 of n pieces of intelligent power ICs 12a to 12n is interrupted due to overcurrent or overheat, an interruption signal is sent from the interrupted part in the interrupted IC 12 to a pulse generator 40. Then, the generator 40 generates a pulse signal having the number of pulses corresponding to the interrupted IC 12 as a switching element to specify the interrupted IC 12 based on the interruption signal. The pulse signal is sent to a transistor TR via a control IC 14a to fire an alarm lamp 22 by predetermined numbers of times. Thus, the intelligent power IC interrupted by small alteration of a software can be easily specified without using a diagnosing unit.

Filed: 1989-03-14
Abstract: PURPOSE:To obtain a narrow directivity both in horizontal and vertical directions by providing plural sound absorbing panels in front of speakers close to the speaker while at least a front face is opened and an acoustic panel whose plate face is directed in the radiation direction of a sound wave at a prescribed interval. CONSTITUTION:A component in a reference axis direction (in this figure, a radiation axis and a center axis of a speaker are coincident) of a sound wave radiating from the front face of a speaker 1 accommodated in a cabinet 4 passes through a gap of a sound absorbing panel 5 and reaches a listening point as shown in the arrow A. On the other hand, in the directions of the arrows B, C obliquely deviated from the reference axis, the sound wave is in touch with the panel 5 and a transmission loss is caused due to its sound absorbing property in the case of transmission and the sound pressure is attenuated. In this case, the direction of the arrow C is absorbed more the number of times than the direction of the arrow B by the sound absorbing panel 5, then the attenuation is increased. That is, As an angle theta with respect to the reference axis is increased, the attenuation is increased, resulting that the speaker equipment having very narrow directivity is obtained.
