Title: Steel material heating furnace and method for controlling combustion in it
Inventor: UEHARA TAKUO
IPC: C21D1/52
Filed: 1996-11-14
Abstract: PROBLEM TO BE SOLVED: To efficiently eliminate skid marks by arranging plural heat-storage type burners at the upper part of a soaking zone in a heating furnace. SOLUTION: Since the heat-storage type burner 3 is the burner, by which the combustion gas in the furnace is absorbed and the other burner is fed and burnt by preheating and circulating the air with a heat exchanger 4, the merit, in which the heat efficiency is good and comparatively high temp. combustion gas is obtd., is used, and about 10 pieces of the burners 3 are parallel arranged in the width direction of the furnace at the upper part 2 of the soaking zone in the heating furnace 1. Then, the burners executing on and off, are arranged as the zigzag state, and the combustion cycle repeates the combustion and the suction of the gas in the furnace in the interval of 1-2mm.  Therefore, the temp. compensation with the burner can be supplied to the temp. of the combustion load or higher, and the heating is executed in the condition near the preset heating temp. curve without bringing about the lowering of the temp. in the soaking zone. As a result, the temp. at the position bringing a cast slab into contact with a skid rail is made to raise, too and the combustion load at the skid part is drastically reduced.

Title: Semiconductor memory
Inventor: KODAIRA SATORU
IPC: H01L21/8244
Filed: 1995-11-21
Abstract: PROBLEM TO BE SOLVED: To suppress the increase of the power supply current of a high- resistance load type SRAM memory at standby time by commonly using a connecting section for connecting a pair of high-resistance elements formed in the extending direction of a word line to power supply wiring. SOLUTION: High-resistance areas 3 and 4 and 5 and 6 in two adjacent memory cells arranged in the extending direction of a word line 14 are constituted to have common connecting sections for respectively connecting the areas 3 and 4 and 5 and 6 to power supply wiring 1. Therefore, the increase of the power supply current of a semiconductor memory can be suppressed, because the lengths of the high-resistance areas can be prolonged by L2 in the word line extending direction in addition to the conventional length L1 in the bit line extending direction and a high-resistance element can be formed without lowering the resistance value even when the sizes of memory cells are reduced.  In addition, when the resistance of the area in which the other ends of high- resistance loads are commonly connected to a power source is lowered, the voltage drop at the branch point of a high-resistance load can be reduced and the data holding characteristic of the memory can be improved.

Title: Detection of surface fault on cast slab on-line
Inventor: KAWAGOE MASAHIRO
IPC: B22D11/16
Filed: 1988-11-30
Abstract: PURPOSE:To detect surface fault on a cast slab containing tearing, depression, etc., on-line by detecting variety with the lapse of time to temp. or heat flux distribution at each point of width direction of a mold for continuous casting. CONSTITUTION:The temp. or heat flux at each point of the width direction of the mold for continuous casting is measured and the distribution of the temp. or heat flux is observed to obtain the variety with the lapse of time to the temp. or heat flux distribution. That is, it is based on the fact that in the case of developing no surface fault on the cast slab, the variety with the lapse of time to the temp. or heat flux distribution in the width direction of the mold is not observed, but on the contrary, in the case of developing the surface fault, the distribution with the lapse of time is largely varied. Therefore, the variety with the lapse of time is detected, and by judging so that in the case of observing the variety, the surface fault is developed or in the case of observing no variety, the surface condition is good, the surface characteristic on the cast slab can be known on-line during casting.

Title: Standby equipment switching signal generating circuit
Inventor: ISHIZUKA MASAHIRO
IPC: H04J3/00
Filed: 1988-12-02
Abstract: PURPOSE:To prevent the occurrence of malfunction of standby equipment changeover if lots of faults take place by selecting a switching instruction of one time slot in one frame with a 1st filter section and selecting a switching instruction in the same time slot with priority by a 2nd filter section. CONSTITUTION:With a switching instruction applied through a signal line corresponding to a highway, a first incoming signal passing circuit 4 passes the first switching instruction of a frame. Moreover, a reference signal generating circuit 3 detects the first switching instruction of the frame, outputs a reference signal to pass only a switching instruction corresponding to the same time slot in the succeeding frame through the circuit 4 to mask the switching instruction corresponding to other time slots. Then a stop detection circuit 5 gives a reset signal to the reference signal generating circuit 3 when the switching instruction of the same time slot in the succeeding frame does not arrive thereby stopping the output of the reference signal. Thus, the masking of the circuit 4 is released to pass the switching instruction of other time slots.
