IPC: G01D9/30
Filed: 1982-08-13
Abstract: PURPOSE:To decrease the missing of sudden signals having large amplitude, by shifting the level of other input to a neighboring channel, suppressing the amplitude of one input or output in correspondence with the magnitude of said voltage, and recording the other input in high priority. CONSTITUTION:Of three channel pen recorders CH1-CH3, the CH2 is recorded in high priority. An amplitude limiter is formed from input terminals 1-3 to output terminals 1'-3', in the area including operation amplifiers A11-A33, transistors Q1 and Q2, and resistors R11-R37. In the same area, a driving amplifier for a pen motor is formed after the terminals 1'-3'. A DC component is applied to the output -e12 from the amplifier A21 by level shifters B1 and B2.

Title: Pattern inspection method
Inventor: ANDOU SANETOSHI
IPC: G01B11/00
Filed: 1978-11-15
Abstract: PURPOSE: To enable to measure the pattern width having a given frequency, by emitting a plurality of light spots different in the wave length on the board on which the pattern of shield light layer is formed and measuring the pattern width of the transmission light strength distribution shield material layer obtained at the photo detector.  
     CONSTITUTION: The laser light from the laser light sources 10W12 in wave length λ 1 Wλ 2  is emitted on the printed board 1 via the half mirrors 13 and 14 and the reflection mirror 15. At a given region of scanning line, the light from the laser light sources 10W12 in shut with the conductive layer and can not transmit the printed board 1, causing the low (L) output level of the detectors 19W21. Accordingly, since the output level of the AND circuit 25 is at L level and the output of the OR circuit 26 is also at L level, the counter 27 performs count operation while the light spot scans the scanning region. In this case, since the output level of the exclusive logical sum circuit 29 is at level, the multiplier 30 directly outputs the count value of the counter. Thus, the pattern width can be obtained from the counter count value and the scanning speed.

Incidentally, if the quantity of sand drawn from the furnace is equal to the quantity of the sand returning to the furnace, the quantity of sand in the sand bin 3 is kept constant. The quantity of the sand drawn from the furnace is controlled according to the deviation of the detected temperature from a set temperature detected by a furnace temperature sensor 10 so that the furnace temperature can be kept constant.
