Title: Laser beam device
Inventor: UCHIDA TAKAHIRO
IPC: B23K26/00
Filed: 1991-12-17
Abstract: PURPOSE:To measure the laser beam intensity with high accuracy by providing the laser beam intensity measured value arithmetic means to search the light intensity of laser beam emitted from an laser beam oscillating unit based on a 1st light intensity measured value and a 2nd light intensity measured value. CONSTITUTION:The light intensity measured value obtained from the light intensity measuring part 48 corresponds to the light reflected at the 2nd glass surface 32b, that is, the light intensity of the reflecting light from the work 30 side. On one side, the light intensity measured value obtained from the light intensity measuring part 40 corresponds to the light intensity of two kinds of light reflected at the 1st glass surface 32a, that is, the multiplied light of the laser beam of the 1st light and the 2nd light that the reflecting light from the work 30 side is entered in the oscillating device 10 amplified and then passed through from the emitting mirror. Based on these correlative relation, the laser beam intensity measuring part 50 searches the light intensity measured value of the original laser beam by subtracting the value that the prescribed constant is multiplied to the data of light intensity measured value from the light intensity measuring part 48 from the value of the data of light intensity measured value from the light intensity measuring part 40.

Title: Interpolating and recovering method for laser doppler type measurement
Inventor: SATO KENJI
IPC: G01S17/58
Filed: 1993-12-30
Abstract: PURPOSE:To accurately measure by interpolating with a correction signal and recovering to the normal state when a measured state being abnormal is decided from presence or absence of a reflected light from a material to be measured, a level, etc., of an input signal to a frequency tracker. CONSTITUTION:When a signal of a reflected light from a material to be measured, a level of an input signal to a frequency tracker or an output frequency of the tracker becomes abnormal, a switching signal is output from a control gate 32. Switching units A, B are switched over to an interpolation side by this signal and interpolgtion signals re output from interpolation signal sources A, B. When a reflected light being 'present' is detected, a search trigger is generated from the gate 32, and a triggering of an input signal level is started. The search is continued until the level becomes 'larger' than a certain value, and the interpolation signals are output during the period. When the level signal becomes 'larger' than the certain level, a frequency at that time is decided, and whether the 'larger' signal is a Doppler signal or pedestal noise, is decided. If it is higher than the decided frequency, it is decided as the Doppler signal, and the interpolation is finished.

Title: Polling controller
Inventor: SHINOHARA NAOKO
IPC: H04L47/32
Filed: 1995-12-28
Abstract: PROBLEM TO BE SOLVED: To rightly perform a polling decision even if the number of bit of a reference time counter determining cell arrival time is reduced in the polling control of an ATM(asynchronous, transfer mode). SOLUTION: The one period of a reference time counter is set to the four times as many as the maximum value of the sum of cell space and a CDV(cell delay variance) allowable value. First and second flags f0i and f1i to be alternately set for every fixed time which is the time corresponding to the maximum value or more are provided. In the polling decision when a cell arrives, the first and second flags f0i and f1i are checked at first (S3), and if the both of the flags are set, the decision as a propriety is performed because satisfactory cell space exists (S6). The detailed polling decision is performed by taking the cell space Ti that a user designates and the expected arrival time TATi determined when the cell arrives before the CDV allowable value τi into consideration, except the decision (S4, S5).  At this time, because the arithmetic range of the decision becomes less than 1/2 of of the period of the reference time counter, the normal decision can be performed even if the reference time counter exceeds the boundary between zero and the maximum value and the reverse rotation of time is generated.
