Title: Control system of commutatorless motor
Inventor: YAMAZOE MASARU
IPC: H02P6/06
Filed: 1986-03-19
Abstract: PURPOSE:To control a lead angle of a converter at side of a motor accurately, by a method wherein signal multiplied from output signal of a position detector mounted on a synchronous machine is used as input current of a pulse distribution circuit. CONSTITUTION:One input of a phase comparator 52 is a position detector signal (a) mounted on a synchronous machine, and another input is output signal (h) of a frequency dividing circuit 55. The phase comparator 52 detects phase difference of the two input signals, output corresponding to the phase difference is smoothed by a filter 53 and then becomes input signal of a VCO 54. The VCO 54 oscillates at frequency depending on the input signal, and the output is inputted to a counter 56 and the frequency dividing circuit 55. Frequency dividing ratio of the frequency dividing circuit 55 is dependent on resolving power of lead angle in the pulse dividing. Output (g) of the VCO 54 is used in place of pulse generator signal in the pulse dividing circuit.

Abstract: PURPOSE:To easily adjust an optical system by eliminating mutual interference between directions X and theta due to Y-directional adjustment by separating an  Y-directional adjustment part for a read line which easily cause mutual interference during adjustment from adjustment parts for other directions. CONSTITUTION:A photodetecting element 25, fitted to a base plate 26, is adjusted in a direction X with an X-directional adjustment screw 28 firstly, and then adjusted in a direction THETA by turning a rotary block 28 with an adjustment screw 29. Then, Z-directional adjustment is performed by providing a lens mount to a lens holder 30 so that it is freely slidable in the Z direction. For Y-directional adjustment, a reflecting mirror 22 fitted to one side 20-2 of a united frame 20 is rotated around a shaft 34.

Title: Optical semiconductor coupler
Inventor: KATSUKI YOICHIRO
IPC: G02B6/42
Filed: 1989-03-13
Abstract: PURPOSE:To inexpensively produce the coupler without the need for working steps to a lens holder and welding ring by forming the opposite surfaces of the lens holder and the welding ring as flat surfaces and fixing the surfaces by resistance welding. CONSTITUTION:The mutual fixing surfaces of the lens holder 12 and the welding ring 13, i.e. the opposite surfaces thereof are formed as flat surfaces without providing the steps thereon. The ring 13 is fixed by resistance welding to the other end of the holder 12. The holder 12 is previously subjected to gold plating in order to fix a lens 4 by solder 11 thereto. The generation of problems, such as weld crack by impurities, such as P, included in the plating and the difference in the weld strength by the reflection of the plating surface does not occur in the case of resistance welding and, therefore, the sure fixing is possible. The need for working the steps to the holder 12 and the ring 13 is eliminated in this way and the inexpensive coupler having high productivity is obtd.
