Title: Measuring method of distribution of film thickness and apparatus therefor
Inventor: NAKADA TOSHIHIKO
IPC: G01B11/06
Filed: 1987-08-28
Abstract: PURPOSE:To measure the distribution of the thickness of a film such as a photoresist in a minute area at high speed and with high accuracy, by a method wherein a two-dimensional interference pattern generated by inner-film interference is separated into wavelength components in the number of N and each component is detected separately from others. CONSTITUTION:A light 11 emitted from an Ar laser 10 is separated 14 into ones going on optical paths 50 and 51 respectively. When the separated light going on the optical path 50 is applied onto a wafer 1' of a photoresist 2, a reflected light 4 from the surface thereof and a reflected light 5 from the interface between the photoresist 2 and a ground substrate 1 interfere with each other and a two-dimensional interference pattern is generated therefrom. This pattern is detected by an objective lens 15 and then separated 17 into those going on optical paths 52 and 53 respectively. The separated interference pattern going on the optical path 53 is subjected to wavelength separation into interference patterns relating to three wavelength components by a wavelength selecting optical system A, and they are imaged on two-dimensional solid-state image sensing elements 19b-19d respectively. The intensity of the interference at each point of these two-dimensional interference patterns is referenced with the relationship between a film thickness and interference which is introduced beforehand and wherein the three wavelengths are parameters, and a two-dimensional distribution of the film thickness is determined finally therefrom.

Title: Magnetic recording and reproducing device
Inventor: KAWASAKI OSAMU
IPC: H02N2/00
Filed: 1983-11-11
Abstract: PURPOSE:To obtain a special reproduced image which is free from noises by controlling the control voltage to be applied to a piezoelectric drive element so that the signal levels are set at the maximum value at plural points obtained by tracing a recording track by a mobile head and therefore absorbing the displacement of the piezoelectric drive element, the variance of sensitivity of the applied voltage and the nonlinear characteristics. CONSTITUTION:The 1-frame precedig head loci 10-1-10-3 and the new head loci 11-1- 11-3 are equal to the detecting points of the signal levels corresponding to each other. A time point t1 corresponds to the points 10-2 and 11-2, and a time point t2 is equal to the time when a track is tracked. The waveforms obtained between times points 0 and t2 of the drive voltage applied to a piezoelectric drive element 23 are divided into two straight lines of time points 0-t1 and t1-t2. Voltage comparators 17-1-17-3 compare the outputs of sample holding circuits 16-1-16-4 which hold signal levels at plural points. An applied voltage control circuit 21 controls the applied voltage in response to the results of said comparisons. Then the drive voltage approximate to a straight line of folded line is applied to the element 23 so as to set the signals of plural points at maximum levels. As a result, the head can always trace on the recording tracks.

Title: Initial program load restart identification system
Inventor: FUJIKI KOJI
IPC: H04M3/22
Filed: 1988-08-26
Abstract: PURPOSE:To decide the phase of restarting an initial program by retrieving a specific address of a memory storing initial program at a central processing unit and identifying the presence of the said address when the load of the initial program is executed at the restart processing in an electronic exchange system. CONSTITUTION:In the case of initial program load(IPL), a CPU 1 reads information of a magnetic tape(MT) 5. When the information is read up to a bootstrap program(BSP), the read information is transferred to an address such as address 40 of a main storage device (MM) 3. The execution is started when the BSP is read. The CPU 1 reads an exchange processing program of the MT 5 and transfers the program to a file program 6. Then the restart processing is started. An IPL restart identifier 4 is operated in the restart phase deciding processing to discriminate whether or not the BSP exists in the address 40. When the BSP exists, the restart phase is decided to restart the IPL and to apply the initial setting of the address 40 of the MM 3. When the BSP does not exist, the restart phase undecision is set as the result of processing.

Abstract: PURPOSE:To obtain a device excellent in operation convenience which a display means can confirm even if the display capacity of the display means is smaller than reading capacity by compressing data read by an image data reading means and displaying the compressed data on the display means. CONSTITUTION:Data read by a handy scanner 31 are stored in a buffer 43. It can store at least data of 80 lines; one line is made of 512 bits. On the other hand, the display of a console panel 30 has a display capacity of 20 lines; one line is made of 128 bits. Therefore, awoug 64 lines (one line contains 8 bits) of data, only the data corresponding to seventh and third bits in each line are read out to compress the data in the line direction. As for the row direction, row data are intermittently read out according to the arithmetical progression of first, fifth, ninth, 13th and fourth rows, and are compressed. Consequently, relatively compressed data can be displayed on a display with relatively small capacity.

Title: Circuit breaker
Inventor: YOKOYAMA YOICHI
IPC: H01H73/18
Filed: 1987-08-25
Abstract: PURPOSE:To enable sure return of a shield plate by furnishing a resetting means for forced return of the shield plate interlocked with off-action of a handle. CONSTITUTION:Resetting after repair of shortcircuiting is made by felling a neutrally positioned handle 6 from the condition shown by assumed line to the off condition on the righthand. Turning of this handle 6 restitutes a tripping means 24 by a return spring 28 to put a latch 23 in latched state. Thereby off state is obtained. A resetting boss 68 of the handle 6 pushes the follower part 73 of a resetting means 71 so as to turn it counterclockwise. When the tripping means 24 is not restituted due to increase of the wear resistance caused by dirt or contact abrasion powder, which has intruded into the gap between a shield plate 9 and a guide 46, an actuating part 74 pushes the tripping means 24 to enable sure restitution.
