Inventor: YAMADA WATARU
IPC: G01B11/22
Filed: 1998-03-18
Abstract: PROBLEM TO BE SOLVED: To enable accurate measurement of the depth of etching in real time even when an etching rate changes in the course of the etching. SOLUTION: In this apparatus, an extremal value counting part 31 counts the number of extremal values in changes in the intensity of reflected diffraction light Q" when a silicon wafer 1 is irradiated with a laser light. An amplitude calculating part 32 determines a difference between the newest maximum and minimum values out of the extremal values obtained by the extremal value counting part 31 to obtain the amplitude of the changes in the intensity of the reflected diffraction light Q" from the difference. An etching function calculating section 33 derives the relationship between the changes in the intensity of the reflected diffraction light Q" and the depth of the etching as etching function based on the surface structure of the silicon wafer 1.  An etching depth calculating section 34 applies the number of the extremal values and an amplitude by the change in the intensity of the actual reflected diffraction light Q" for the etching function derived by the etching function calculating section 33 to determine the etching depth.

Title: Data transmitter
Inventor: NAKATSUKA SHIGEO
IPC: H04L1/00
Filed: 1981-05-07
Abstract: PURPOSE:To achieve error detection without lowering an effective transmission speed by equalizing the inspection time when an error is detected by detecting a change of a flag in a frame to the time for the longest telegraphic message transmission of data sent out of a terminal. CONSTITUTION:The flag K of a CH1 consists of two bits and logic ''0'' shows that a data frame is empty; and the 1st bit is set to ''1'' for a use state of the 1st kind and the 2nd bit is set to ''1'' for that of the 2nd kind. When said flag K is set to ''1'' continuously between time t0- time tz owing to a noise, etc., inspection time Tf is nearly equal to time Tm required by one terminal TU to send a telegraphic message of the longest length, and consequently even if the K is set to ''0'' after some terminal TU finishes transmitting a telegraphic message and another terminal TU starts using the same channel before the ''0'' arrives at a channel recovery device (ECR)5, the K is set to ''2'' once without fail and it is detected by the ECR5. Therefore, if the ''0'' or ''2'' is not detected even once during said period Tf, the channel is discriminated as an error and the K is set forcibly to ''0'' at time tz.

Abstract: PURPOSE:To measure torsional vibrations at any position from the torsional vibrations to be  detected at a fixed position by using the facts that the torsional vibrations to be established in a  rotary shaft system are the sum of vibrations of different modes and that the vibrations of different modes are expressed by the product of the vibratory mode forms and components. CONSTITUTION:Torsional vibrations are detected at an n number of fixed positions of a rotary  shaft system by means of n number of detectors 7, and the respective torsional vibrations obtained are decomposed by a decomposer 9 into the vibrations of orders higher than (n+1)th order  intrinsic to the shaft system so that the subtraction is accomplished in a subtracting device 10. In  a matrix calculator 11, an n number of the summed vibrations up to an nth order are multiplied  by an n number of groups of n constant, which are obtained in advance, for each group so that  their summations are taken to obtain the vibratory mode components up to the nth order. In a  first mode calculator 13, the respective mode of vibrations up to (n+1)th order at any position  are obtained, whereas in a second mode calculator 12 the mode of vibrations up to nth order at  the same position are obtained. The vibrations of the respective modes obtained in these two  ways are added by an adder 14 so that the torsional vibrations at any position are obtained.

IPC: G04C9/04
Filed: 1994-04-07
Abstract: PURPOSE:To avoid the occurrence of the overlapping of data and the failure in measurement by avoiding such inconveniences as the overlapping of the same time and the missing of a certain time in synchronizing the time indicated by a clock with a standard time. CONSTITUTION:When a terminal station receives time-setting commands sent from the central station (S1), it compare a standard time of them with the present time indicated by a clock in the terminal station to judge whether the deviation between both times is within a correctable range or not (S2). If the deviation is within a correctable range, the terminal station conducts a time-correcting process (S3). In the time-correcting process, the time indicated by the clock is corrected by compressing or extending the time base of the real time in each specified hour and converting it on the time base of the clock. On the other hand, if the deviation between both times is outside a correctable range, the terminal station conducts a compulsory time-setting process to synchronize the time indicated by the clock with the standard time forcibly (S4).
