Abstract: PURPOSE:To obtain a stable laser output continuously over a long time by a method wherein the degree of cleanliness inside a light path is always monitored and a clean gas is supplied according to the detection result by using a monitor. CONSTITUTION:When a laser beam is passed through light paths 17, 17 during a laser oscillation operation, it is scattered by dust particles existing inside the light paths 17, 17; scattered light caused by the dust particles is always monitored by using detectors 28, 28. When the air inside the light paths 17, 17 is contaminated to a certain extent, the intensity of the scattered light detected by using the detectors 28, 28 exceeds a set value which has been set in advance in a reference-signal generation circuit 30.

Title: Printed wiring board
Inventor: YAMAZAKI TAKASHI
IPC: H05K3/00
Filed: 1991-11-25
Abstract: PURPOSE:To decide the quality of the working accuracy of a V-groove i.e., the division accuracy of a board through visual observation by printing a pattern on the division target line of a board surface. CONSTITUTION:On the surface of a printed wiring board 1, a plurality of check patterns P1, P2 and P3 for visually confirming the accuracy of a V-groove are printed in a line along the target line L of board division. In this case, when a target V-groove width is Wa, there exists the relation of Wa>W1, Wa=W2 and Wa<W3 between respective pattern widths W1, W2 and W3 of the check patterns P1, P2 and P3. When the V-groove can be formed with an accurate width along the division target line in the printed wiring board 1, all checking patterns of P1 and P2 disappear and only both ends of the check pattern P3 with the maximum pattern width are left with an equal width. Thus, when the check pattern is visually confirmed after the V-groove has been cut, it is possible to decide whether the working accuracy of the V-groove is good or not.

Title: Input buffer circuit
Inventor: KAJII KIYOSHI
IPC: H03K19/0185
Filed: 1990-11-15
Abstract: PURPOSE:To avoid deviation in a transfer characteristic attended with a side gate effect by shifting positively a threshold level of a FET for constant current equivalently. CONSTITUTION:When a threshold level of a depletion type 1st FET of a 1st series circuit or a threshold level of a depletion type 3rd FET of a 2nd series circuit is shifted positively by a side gate effect, a threshold level of a depletion type 6th FET supplying a current i6 to a voltage application means applying a voltage Vm to a gate of an enhancement type 5th FET 5 whose source (drain) connects to a 2nd power supply is similarly shifted. When the current i6 flowing to the 6th FET is decreased, the voltage Vm is decreased, resulting that a current i6 flowing to the 5th FET 5 is decreased by the gate voltage decrease. The current i5 is changed similarly to a change in a current i1 or i3 flowing to the 1st FET or the 3rd FET and the current i5 and the current i1 or i3 is balanced thereby avoiding the deviation in the transfer time characteristic attended with the side gate effect.

Title: Computing apparatus for peripheral length of object
Inventor: YONEYAMA HAJIME
IPC: G06T7/60
Filed: 1989-11-30
Abstract: PURPOSE:To shorten the computing time of the peripheral length of an isolated object by obtaining the difference between the total area of an image of the object within a binary image and the partial area with peripheral pixels removed from the image of the object. CONSTITUTION:A binary image data B is inputted in time sequence synchronously with a clock signal CLK. In a data synchronizing circuit 1, data of both an optional pixel and a predetermined number of pixels adjacent to the optional pixel is outputted in time sequence for the whole of the binary image by line delay circuits 11, 12 each of which makes one line delay to the data B in a horizontal or vertical direction, and latch circuits 13-16 each of which gives a delay of one pixel. A partial area computing circuit 2 counts clocks synchronous with the data B only when the data outputted from the circuit 1 are all in the high level, and counts the remaining number of pixels left after the peripheral pixels are removed from the image of the isolated object. On the other hand, a total area computing circuit 3 counts clocks only when the data B is high, so that the total number of pixels of the image of the isolated object is counted. A subtracter circuit 4 subtracts the outputted value of the circuit 2 from that of the circuit 3. Accordingly, the peripheral length of the object present in the data B can be known.

Abstract: PURPOSE: To enable automatic consecutive opening and separating thermoplastic grocery or retail product bags of a T-shirt type by making separation strength of an adhesive means greater than that of a bag mounting tab and making it smaller than resistance against slide of the bag along a support arm of a rack. CONSTITUTION: In removing respective loaded bags 12 from a rack 30, resistance against slide of the bag along an exterior extending toward a side of a support arm 33 is greater than separation strength of an adhesive means 26, so that the adhesive means 26 between the bag 12 is separated from a rear wall 16 of the loaded bag and a front wall 15 of a subsequent bag 12. In addition, since separation strength of the adhesive means 26 is greater than that of a mounting tab 20, the mounting tab 20 on the front wall 15 of the subsequent bag 12 is separated before the adhesive means is separated, whereby the subsequent bag 12 is pulled from a bag pack 14 to an open loading position on the support arm 33.

Title: Transmission method for acoustic signal
Inventor: YOSHINO OSAMU
IPC: H03M7/30
Filed: 1992-10-23
Abstract: PURPOSE:To attain the transmission of an acoustic signal with high quality by high efficiency-encoding an acoustic signal by obtaining a number of changes in a primary moment of amplitude components for each discrete frequency and comparing the number with a predetermined value when a digital acoustic signal is subjected to Fourier transformation. CONSTITUTION:A frame signal segmented from an acoustic signal is subjected to discrete Fourier transformation by using the same window function and the primary moment of the amplitude component for each discrete frequency. Then a frequency DELTAfi outputted from a subtractor 47 of a primary moment frequency calculation section 45 is compared with a predetermined value at a discrimination circuit 48 based on an adaptive quantization control signal at a bit number information generating part 37 and the result of discrimination is given to a signal generating circuit 49. When the change in the primary moment frequency of the amplitude component of the acoustic signal is large, original data are sent. On the other hand, when the change in the primary moment frequency is small, data with less bit number allocated are formed and the acoustic signal is sent with a high efficiency.
