Title: Light converging device and film thickness measuring instrument
Inventor: YAMAZAKI CHIKAYASU
IPC: G02B6/04
Filed: 1985-04-12
Abstract: PURPOSE:To measure the thickness of a film even during the movement of an object of measurement by providing a photodetection part, a light projection part, and a parallel light generating means which collimates light from the light projection part into parallel light, and guiding the light from the parallel light generating means to a spectroscope. CONSTITUTION:Light from a white light source 1 is converged on a pinhole 3 by a lens group 2 and a collimator lens 4 collimates the light from the pinhole 4 into the parallel light. This parallel light illuminates a film thickness measurement point 14 at a constant angle through an incidence window 17 and is reflected by a surface to be measured. In this case, even if the direction of the reflection varies irregularly owing to wrinkles, etc., of the object of measurement, the reflected light is photodetected at any photodetection position with the same efficiency as long as the variation is within a range of + or -45 deg. abaut the the regular direction of reflection. This photodetected light is propagated in an optical fiber and projected from the end surface of the light projection part 19. When the parallel light is reflected by the measurement object surface, the light varies in spectral intensity. This variation depends upon the film thickness as long as the refractive index of the object of measurement is constant, so variation in the spectral intensity is detected to find the film thickness.

Title: Improvement of accuracy in shape detection
Inventor: IKEDA SOUHEI
IPC: B23K1/00
Filed: 1983-05-04
Abstract: PURPOSE:To improve detection accuracy in the stage of detecting the three- dimensional shape of a soldered part by a light cutting method by coating a matting agent on the surface of the part to be detected or adding a specific metal to the solder to eliminate the luster. CONSTITUTION:A matting agent is coated on the surface of solder 3 or Ag, Cd or the like is added into the solder and such solder is used to make the surface of the solder 3 non-lustrous in the case of judging whether a micro-soldered joint is satisfactorily connected or not by a light cutting method. If slight light 6 is projected from a slit light projector 5 onto such solder 3, the reflected light is uniformly distributed 9 in the entire direction owing to lack of the luster and the reflected light 11 to a detector 7 is larger than the case in which there is luster. The detected image is thus stabilized and the reliability of the detection rate in a deciding part 8 is improved.

Title: System-interconnected inverter device
Inventor: ARINOBU HIRONORI
IPC: H01L31/04
Filed: 1995-04-03
Abstract: PURPOSE: To provide a system-interconnected inverter device which detects an off-state of a commercial power system accurately and then stops supplying of power, in the case where a frequency shift method is used. CONSTITUTION: When a commercial power system 2 is normal, a closed loop from a phase comparing circuit 15 through a voltage controlling and oscillating circuit 19 operates mainly. A converting section 11 generates the AC output of the same frequency as that of the commercial power system 2 which is a reference frequency. When the commercial power system 2 is in an off-state, there is no reference frequency on which the closed loop should operate and therefore the frequency of the AC output becomes unstable and a fluctuation in the frequency appears. A bias generating section 18 detects the fluctuation in the frequency and then generates a second detecting signal of such a level as to correspond to the fluctuation.  An adding circuit 17 adds the second detecting signal to a first detecting signal from a smoothing circuit 16 and then outputs the result to the voltage controlling and oscillating circuit 19 as a control input. Since the converting section 11 generates the AC output which has a big fluctuation is frequency, a fluctuation in frequency at an interconnection point 202 is detected and then the supply of the AC output is stopped.

Title: Voice signal communication system
Inventor: TADA SHINKO
IPC: H04B1/44
Filed: 1991-04-10
Abstract: PURPOSE:To reproduce a voice signal without generating cut off of the head of speaking on the receiving side at the time of switching transmission by transmitting coded voice signal after applying a delay equipment to a time required for synchronization establishment to the coded voice signal on the transmitting side. CONSTITUTION:A voice signal digitally coded by a coding circuit 2 is temporarily stored in a memory buffer circuit 5, and after the lapse of a delay time previously set by a delay time setting circuit 6 the stored voice signal is sent to a modulator 7. A synchronizing flag signal is inserted into the delay time. The synchronizing flag signal indicates the start of the coded voice signal after the lapse of a prescribed time from the end of the signal. The transmitting signal modulated by the modulator 7 is sent to an output amplifier 8 and power- amplified and the amplified signal is radiated from an antenna 9 to air. Since the output of the coded voice signal is delayed on the transmitting system side A only by the time required for the synchronization establishment on the receiving system side B, the voice signal can be reproduced without generating cut off of the head of speaking on the receiving system side B.

Abstract: PURPOSE:To raise the control accuracy by detecting a position and a speed of a driven side against a position fluctuation of a main driving side and compensating a speed control of the driven side by a feed forward control of a load torque of the driven side which has been estimated from a detection value. CONSTITUTION:An input signal thetaref is inputted, added to a manipulated variable (u) which has been led out of a leading-out point (a) as an assumed desired value for estimating a load torque Ts of a driven side, and a rotation angle chi' of the driven side is estimated. This rotation angle chi' is brought to feedback by an optimum feedback gain function E and added to the input signal thetaref, brought to feedback to an adding point (b), and also, compared with an output signal chi at an adding point (c), and its difference is brought to feedback to the adding point (b) and corrected. In such a way, based on the estimated rotation angle chi', the load torque Ts is estimated, and based on the estimated Ts, a compensation input is executed to the input signal thetaref by an optimum feedforward gain function M. Accordingly, the control accuracy can be raised.
