Abstract: PURPOSE:To accurately measure an interference of a surface to be inspected, having a  large area, by placing the surface to be inspected, obliquely against the reflected reference surface, and constituting so that parallel inspecting light which have been made incident obliquely against the surface to be inspected are reflected by the surface to be  inspected, and go back through the reflection surface. CONSTITUTION:A laser emitted from a laser source 1 becomes a spot light source  through a light quantity adjusting filter 2 and a condensing lens 3. Its light becomes  parallel light by a collimator lens system through a polarized plate 5, a part of its  light is reflected by a semitransparent reference plane 7, becomes a reference wave surface, goes back and is reflected by a semitransparent mirror 4, and forms a point  image PA. On the other hand, a light which has transmitted the semitransparent reference plane 7 is made incident obliquely to a surface to be inspected 8, is reflected and  is made incieent to a reflected reference surface 9. Its reflected ray goes back, is reflected by the semitransparent mirror 4, and forms a point image PB. The reflected  reference surface is adjusted by inserting an alignment lens 12, a coupling image of the  point images PA, PB is formed simultaneously on an observation surface 10, and after  that, a cylindrical lens is inserted. In this way, the surface to be inspected 8 having a  large area is measured with high accuracy.

Title: Speed controller for dc brushless motor
Inventor: SAITO MORIHIRO
IPC: H02P6/08
Filed: 1991-04-03
Abstract: PURPOSE:To provide a speed controller for a DC brushless motor of simple constitution and not requiring cost. CONSTITUTION:When it is a normal rotation command, a driving signal is distributed to each transistor, FET, of an inverter transistor circuit 7 from a distributing circuit 4, and a synchronous motor 8 rotates normally. The signal sending from a comparator 3 to the distributing circuit 4 is inhibited by a reverse rotation detector 5. When it changes into a reverse rotation command, a forward reverse rotation changeover circuit 6 is changed over on the side of reverse rotation, and the logic condition from the position detector 1 is inverted and the synchronous motor 8 is inverted. When the speed of the synchronous motor 8 exceeds the speed of the speed command, the output of the comparator 3 is inverted, and the distributing circuit distributes signals that turn the transistors UP, VP, and WP on and that the FETs UN, VN, and WN off, and power generation is braked. When the motor speed drops below the speed of the speed command, the distributing circuit 4 distributes a driving signal to the inverter transistor circuit 7 again. This way, power generation is braked intermittently in driving of reverse rotation, and the synchronous motor is controlled into the speed in accord with the speed command.
