The tension to be applied is preferably >=1 kg/mm<2>. The thin steel sheet having the small in plane anisotropy, good workability and exellent ridging resistance is thus obtd. as-rolled without executing not only the conventional cold rolling but also recrystallization annealing by the high draft and high strain rate rolling under the application of the tension in the above-mentioned temp. range.

Title: Torque meter
Inventor: KINOSHITA KAZUTO
IPC: G01L3/10
Filed: 1988-02-29
Abstract: PURPOSE: To enable measurement even when a shaft does not rotate and to measure exact torque without being affected by temp. by transmitting the current to be passed to excitation coils and the voltage of detecting coils between a static side and rotating side by means of two rotary transformers.  
     CONSTITUTION: The mating area of teeth 10a, 10b for detection wound with the detecting coil 13a changes differentially with the angle of torsion by the torque and, therefore, the magnetic resistance thereof changes differentially as well. The quantity at which the magnetic fluxes generated by the excitation coil 11a, 11b pass the inside of the coils 13a, therefore, change differentially without the torque and the voltage proportional to the torque is obtd. by differentially connecting the coil 13a and the other detecting coil not shown. Since the rotary transformers 14a, 14b and 15a, 15b are used for transmission of the rotating side and the static side, the measurement of the torque is feasible even at the static time. The magnetic fluxes to be generated in the excitation coils are kept constant even if the magnetic permeability of the toothed rings changes with a temp. change and the exact measurement of the torque is enabled by maintaining the AC current to be passed to the excitation side rotary transformer constant.

Part of the dry air is sent to a heater 5 through a flow rate meter 6 and heated to be sent to the tower 1a which adsorbed water vapor. The air used for the regeneration of the adsorbent 2 by heat-drying the adsorbent 2 in the tower 1a and removing adsorbed water vapor, after being sent with water vapor, is cooled by a cooler 7 to be discharged in the air through the change-over valve 3. Since the valve 3 is not exposed to high temperature air, an inexpensive solenoid valve of room temperature specifications can be used.

Title: High-speed semiconductor device
Inventor: IMAMURA KENICHI
IPC: H01L21/331
Filed: 1986-03-04
Abstract: PURPOSE:To contrive to let titled device have a many-valued memory function while the device maintains a high-speed efficiency by a method wherein an inverse conductive type emitter layer having a wider energy gap compared to that of a one conductive type base layer and a collector layer, which opposes to the inverse conductive type emitter layer through this base layer and consists of a superlattice, are provided. CONSTITUTION:In case a collector layer 3' is formed of a superlattice, an energy subband SB is produced there and a resonance tunneling phenomenon is generated. Therefore, only at the time a base-collector voltage VBC is set at a certain value, a collector current Ic abruptly flows and in the case of a value other than that, the current Ic comes to remarkably decrease. From these facts, the collector current Ic shows a peak to a certain collector-emitter voltage VCE in the collector-emitter voltage VCE-collector current Ic relation as well. Now assuming that the characteristic curve of the collector-emitter voltage VCE to the collector current Ic is CL, the load line is LD and the intersections of the both lines are, for example, CP1, CP2 and CP3, this device comes to show three kinds of memory functions while maintaining a high-speed efficiency.
