Title: Equipment for measuring thickness of thin film
Inventor: ANSONII EMU RETSUJIYAA
IPC: G01B11/06
Filed: 1992-12-07
Abstract: PURPOSE: To measure the thickness of a wafer layer without requiring any mechanical scanning by an arrangement wherein a wafer is irradiated sequentially with monochromatic lights of different wavelength and the characteristics of reflected light are compared with reference characteristics corresponding to a known thickness. CONSTITUTION: A white light source comprising a halogen lamp 10, a condenser lens 12, and a circular opening 14 is used. A light from the white light source is passed through a focus lens 16 to produce a light beam 15 which is then projected onto a wafer 24. The white light is filtered spectrally through a series of narrow band filters 17 arranged around a rotary wheel 18 and generating a series of focused monochromatic light beams 19 of different wavelength sequentially. A fringe pattern image is reflected on the surface of the wafer 24 and projected onto a CCD camera detector array 31 through a focus lens 22 and a mirror 26. The reflection data is digitized through a digital circuit 34 and compared with a reference data corresponding to a known thickness thus determining the thickness of a thin film layer.

Abstract: PURPOSE:To automatically correct the chart names or the chart numbers contained in the sentences by producing a table of contents of charts at the end of input with use of the chart names or the chart numbers based on the key input which instructs the production of the table of contents of charts. CONSTITUTION:In the case the chart numbers 3 to be written together, the reference chart numbers 3' or the chart names 4 are inputted in an input or correction mode through an editing screen 1, the identification lines 5 or 6 are displayed at the input parts. Then a production key for table of contents of charts is pushed after the input or the correction is through. Thus all pages where the identification lines are shown are extracted for production of a table of contents of charts. In the case the insertion of a chart name is desired on a screen of the table of contents of charts, a cursor is moved to the part of a chart number and a specific key is pushed. Thus the charts following the relevant chart number are all corrected into the following chart numbers and displayed. Then a blank space equivalent to one line is added onto the cursor. In such a way, the table of contents of charts is automatically produced. In addition, the chart name or the chart number can be automatically corrected in a document just by correcting the table of contents of charts.

Abstract: PURPOSE:To take a contact length larger at holding and inserting times and to hold firmly in the inserting work into the hole of a long shaft, by providing plural holding members divided movably in the length direction of a finger member, on the finger member. CONSTITUTION:In the case of holding a long sized shaft, air is first poured into an internal part space 49a through an air tube 50a by an air pump. On pouring of the air, the volume is expanded because of the capacity of the air in the movable holding face internal space 49a being increased and plate members 45a-48a are flared in the lower direction along a guide shaft 31a. Accordingly a flexible member 55a is flared, so movable holding faces 35a-38a are gradually flared and stand still at a constant interval. Moreover, the internal pressure is increased on pouring air further and a hard finger is formed. The shaft is held in this state and inserted into a hole. At this time, a firmly holding state can be maintained because of the contact length being long enough, even in case of the misregistration of the shaft and hole being caused.

Title: Servo motor position controller
Inventor: OKANO YOSHIHIRO
IPC: H02P29/00
Filed: 1991-12-12
Abstract: PURPOSE:To limit the maximum speed of a servo motor of low torque and high speed and to execute stable position control by saturating deviation caused by position feedback by a limiter first and starting a speed control mode when the position deviation is large. CONSTITUTION:A first deviation calculation part 7 calculates the deviation of an output signal theta, which is impressed through a buffer amplifier 3, from a position sensor 2 from a target position R. A limiter 8 limits the amplitude of an output signal from the first deviation calculation part 7. A second deviation calculation part 9 calculates the deviation between the output signal of the limiter 8 and a speed signal Komega.omega outputted by a speed calculation part 4. When the output signal of the deviation calculation part 9 is impressed, a driving amplifier 6 amplifies this signal and drives a servo motor 1. Namely, the factor of saturation caused by the limiter 8 is added to the output of the position deviation. Thus, a speed omega of the servo motor 1 having low torque and high-speed rotation, namely, having the large position deviation is controlled at fixed maximum speed, and the maximum torque can be stably held.
