Inventor: YAMAUMI YOSHIYUKI
IPC: G06T7/00
Filed: 1996-07-04
Abstract: PROBLEM TO BE SOLVED: To precisely read the line width of a circuit pattern on a printed wiring board by receiving transmission light passing through the printed wiring board from a light source and outputting a circuit pattern picture data in an image sensor and detecting the transmission light and controlling the light emission of the light source in an optical sensor.

Title: Voice encoding/decoding device
Inventor: WAKE YASUHIRO
IPC: H04B14/04
Filed: 1990-08-10
Abstract: PURPOSE:To reduce transmission delay by demodulating a V21 signal on an analog line by a FAX signal demodulator, and successively transmitting this data to a digital line. CONSTITUTION:The V21 signal for one frame of an analog signal transmitted from a FAX terminal to an analog line 13 is demodulated by a demodulation part 14 of a FAX signal demodulator 19 and afterwards stored in a buffer 15. As soon as the data length becomes one byte, this buffer 15 transmits the data through a multiplexer 18 to a digital line 20 successively. Next, a modulation part 22 of a FAX signal modulator 24 modulates the data received from the digital line 20 through a separator 21, and the modulated data is converted to the V21 signal for one frame of the analog signal and outputted to an analog line 25. At such time, when an error generator 23 detects an error information data, the modulation part 22 stops modulation by receiving this error signal and invalidates the previously transmitted V21 signal by preventing the normal frame from being transmitted to the analog line 25. Thus, transmission delay can be reduced.

Title: Formation of tantalum film for x-ray mask
Inventor: YAMADA MASAO
IPC: C23C14/34
Filed: 1986-09-09
Abstract: PURPOSE:To decrease the internal stress of a formed thin Ta film to a low value having decreased dispersion, by impressing the electric power which is not lower than the lower limit value of the discharge electric power when the formed thin Ta film exhibits always a tensile stress regardless of the fluctuation in sputtering gaseous pressure. CONSTITUTION:Sputtering is executed by disposing a Ta plate having a prescribed diameter above a magnet as a target, impressing a negative voltage to said plate, disposing an Si substrate formed with an X-ray transparent membrane opposite to the target and impressing a positive voltage to said substrate, then reducing the pressure of gaseous Ar. The curve indicating the relation between the gaseous pressure rhoand the internal stress sigma of the formed thin Ta film passes the internal stress sigma=0 point and the gradient near the same is steep when the discharge pressure P is small, as shown in the figure. Namely, the internal stress is a tensile stress and the gas has a compressive stress with a slight fluctuation in the gaseous pressure and the dispersion of the value thereof is large. On the other hand, the sigma-rho curve has a gentler gradient with an increase in the discharge electric power. The value of the internal stress of the thin Ta film is as low as 5X10<9>dyne/cm<2> at 4kW even if the gaseous pressure fluctuates.

Title: Projection exposure device
Inventor: TANIMOTO SHOICHI
IPC: H01L21/027
Filed: 1985-09-24
Abstract: PURPOSE:To maintain the constant projection status by a method wherein the pressure in air chambers is constantly controlled to pressurize lenses (optical elements) in one direction only while the pressure controlling the air chambers is offset. CONSTITUTION:A constant pressure control system 30 is actuated to keep air chambers A, B at constant pressure not exceeding the lower limit value of (760-P2)mmHg of controlled pressure value in the other air chambers H, N or exceeding the upper limit value of (760+P1)mmHg of the same. Therefore lens elements G2-G4 are constantly subject to a stress in one direction only regardless of the controlled value in the air chambers H, N, i.e. the signs of differential pressure are specified either in positive or negative only without changing from positive to negative or vice versa. Thus the fixing of lens elements G2-G4 to a mirror cylinder can be devised in terms of said sign rule so that the lens elements G2-G4 may be restrained from long time fluctuation. Through these procedures, the titled device can maintain the excellent image formation characteristics under no influence of looseness of lens elements.

Now if a fault arises at a transmission line A, the data signal is interrupted at an end office 12-i with the circuit 1 and an end office 12-(i+1) with the circuit 2, respectively. Thus the fault of the data signal is detected by the SV7 as well as detecting circuits 11-1-11-n corresponding to all end offices 12-1-12-n. Then each of control circuits 10-1-10-n of each corresponding end office is actuated with the corresponding detecting signal. Thus folding circuits 13-1-13-n are formed, respectively. In such a way, all end offices are formed into a folding circuit respectively. Each end office of a folding circuit form releases a folding circuit 13-j with actuation of a control circuit 10-j due to the corresponding detecting signal and is reset to an end office 12-j of a steady state  after detecting the data signal by a detecting circuit 11-j.
