Abstract: PURPOSE:To produce a grain oriented electrical steel sheet exhibiting an excellent iron loss value by pressing the electrical steel sheet subjected to finish annealing at a specific temp. to form recesses then subjecting the steel sheet to a heat treatment at a specific temp. CONSTITUTION:The electrical steel sheet subjected to the finish annealing or an insulating film treatment after the finish annealing is formed with the recesses of a linear, dotted or broken line shape by, for example, a gear type roll under 70-220kg/mm<2> average load in a 50-500 deg.C range. The optimum shape of the recesses is 1-20mm space between the recesses and recesses with regard to the rolling direction and 10-300mum width of the recesses. The depth of the recesses is preferably larger than 5mu in the base iron part of the steel sheet. The direction of the recesses is made 45-90 deg. with regard to the rolling direction.Such electrical steel sheet is then heat-treated at 750 deg.C to generate the fine recrystal grains in the crystal grains, by which the magnetic domains are finely segmented. The grain oriented electrical steel sheet exhibiting the excellent iron loss value equiv. to the iron loss value of the electrical sheet formed by laser irradiation is thus obtd. even if the stress relief annealing is executed.

Title: Substrate detecting device
Inventor: NAGASHIMA ISAO
IPC: H01L21/67
Filed: 1981-12-21
Abstract: PURPOSE:To detect a transparent or semitransparent wafer, by utilizing a light emitting element, a light receiving element, and two polarizing elements. CONSTITUTION:A photosensor is constituted by the light emitting element (a), the light receiving element (photodiode) (b), and the two polarizing elements (e) and (f) which are arranged on an optical axis connecting the elements (a) and (b) so that polarization axes are crossed at a right angle. The light emitted from the light emitting element (a) passes the polarizing element (e), and only a component in one direction (e.g. vertical direction with respect to the paper) remains and reaches the polarizing element (f). Since the polarization axes are crossed at a right angle, the component does not reach the light receiving element (b). when a substrate C such as sapphire on an O-ring belt (d) reaches the optical axis, the light which has passed the polarizing element (e) is subjected to the polarization or scattering again, and a component in the other direction (parallel with the paper) is obtained. Therefore,said light reaches the light receiving element (b). Based on the change in the output voltage from the light receiving element (photodiode), the substrate wafer can be detected.

Title: Ultrasonic distance measuring apparatus
Inventor: TAKAHASHI HIDEYUKI
IPC: G01B17/00
Filed: 1982-11-27
Abstract: PURPOSE:To make it possible to test the operation state of a transmitter receiver even when a reflector is absent, by forming a false receiving pulse by utilizing the attenuation characteristics of the transmitter receiver. CONSTITUTION:The amplification degree of an amplifier 8 is made variable while an AND gate 16 is closed and an AND gate 19 is opened when measurement is performed by the signal of a test circuit 15. On the other hand, the gate pulse from a gate circuit 14 is imparted to the AND gates 16, 19. In testing, the gain of the amplifier 8 is increased and the output of a shaping circuit 9 is applied to FF10 through and AND gate 16 and an OR gate 17. As a result, if a transmitter receiver 5 is normal, the tail end of attenuation vibration is detected and a receiving pulse is obtained in FF10. In this case, the transmitter receiver 5 is judged as normal and, when attenuation vibration is not detected, as inferiority. By this method, the operation state of the transmitter receiver can be tested even when a reflector is absent.
