Abstract: PURPOSE:To enable joining with high accuracy and to greatly improve the yield of products by subjecting a single crystal plate and polycrystalline plate subjected to precision height adjustment to float polishing and applying of an acid soln., then sticking the mirror finished surfaces thereof to each other and subjecting these crystal plates to pressurizing and heating treatments. CONSTITUTION:The single crystal plate and the polycrystalline plate are subjected to preliminary height adjustment by grinding using stationary abrasive grains then to precision height adjustment and half mirror finishing by polishing using the stationary abrasive grains. The work strain layers are then removed and the surfaces are finished to nearly the perfectly mirror finished surfaces by executing float polishing using iron red and a tin surface plate. The mirror finished surfaces of the single crystal plate and the polycrystalline plate coated with the son. of the acid are brought into contact with each other and are subjected to the first heat treatment in a pressurized state, by which these plates are temporally joined. pressurizing state is then released and further, the plat than the first heat treatment temp. by which the crystal plates are subjected to normal joining. Generation of warpage is prevented by the float polishing and in addition the internal stresses are relieved in this process for production and, therefore, the deterioration in the magnetic characteristics is prevented.

IPC: H02K23/04
Filed: 1996-03-31
Abstract: PROBLEM TO BE SOLVED: To reduce the size and weight of a magnet motor to be used in an electric car, etc. SOLUTION: A stator core 31 has large-diameter sections 32 and small- diameter sections 33. The stator 31 is pushed into a case 50 to form a stator 30. The stator core 31 is pushed into the case 50 by the minimum-diameter sections 33, so the thickness of the case 50 at the pushed sections which secures a press-fit strength when the stator core 31 is pushed into the case 50 can be made larger than that of the maximum-diameter sections of the stator 30, and a sufficient press-fit strength can be obtained. The maximum-diameter sections 32 of the stator 30 are not pushed into the case and the thickness of the case at that sections can be made small and hence the size of the entire device can be reduced.

Abstract: PURPOSE:To decrease permissible losses in transmission by duplexing a transmission system and switching automatically the system by reduction in optical reception level. CONSTITUTION:When a reception level is lower than an alarm level determined in advance due to any fault, a system N is switched into a system E by a selection circuit 7 automatically and the signal is received to detect the level of the output of a preamplifier 54 by a peak value detection circuit 55, and when the level is lower than the reference potential Vs, the output of a comparator 56a changes from H to L, and the selection circuit 7 selects the input B in place of the input A. In this case, when the level of a system E is lower than the alarm level, the changeover from the system N into the system E is inhibited by a changeover inhibition circuit 8 comprising an AND circuit 81 and a NOR circuit 82. Thus, maintenance is applied to the system E for the operation of reference photodetection level.
