Title: Emergency shutdown valve
Inventor: SAWADA YOSHIHIRO
IPC: F16K31/72
Filed: 1979-06-14
Abstract: PURPOSE: To enable to surely shutdown a flow conduit even in the event of an electric system trouble by enabling to cancel the stopper working either through a solenoid or a pressure sustaining member.  
     CONSTITUTION: An emergency shutdown valve is displaced accompanying a transport fluid dynamic pressure change and also is provided with a pressure sustaining member 13 mechanically interlocked with a stopper 11 and a solenoid 14 interlocked with the stopper 11. Since said constitution enables it to do the function cancelling operation of the stopper 11 through the solenoid 14, it is possible to shutdown the flow conduit R and to check the fluid flowing-out to the minimum by closing the valve before the breaking of the tube 1 accompanying an extraordinary state generation or before losing a large quantity of fluid after damage by operating the solenoid 14 in connection with a vibrometer. Moreover, even in the event of the electric system breakdown on account of the transport fluid dynamic pressure displacement accompanying the damaged tube 1 the pressure sustaining member 13 can operate to cancel the function of the stopper 11.

Title: Image input device
Inventor: KAMIMURA TOSHIRO
IPC: H04N1/40
Filed: 1989-03-29
Abstract: PURPOSE:To improve the deterioration in picture quality causing a difference in each sensor output by measuring the gamma characteristic of each of plural image sensor elements in use prior to the picture input of an original, indexing a correction curve corresponding to each image sensor and making the correspondence to the relation. CONSTITUTION:A scan timing generator 9 sets a scan period of an image sensor 1 and a data subject to digital input conversion by an A/D converter 3 is written in a line memory 4. Then a CPU 6 reads the content of the line memory 4 to sample the data by a decided number for each sensor chip and the average is obtained by each chip to obtain an output level of each chip. Then the CPU selects a curve correcting the sensitivity characteristic depending on the sensitivity characteristic and outputs the number of the curve in a binary number and the result is outputted to latches 7-1 to 7-N. Thus, since the sensitivity of each image sensor is corrected, in the case of reading an intermediate tone original, the read density of each sensor is made equal to improve the deterioration in the picture quality.

Title: Formation of resist pattern, method and device for correcting dimension, and manufacture of semiconductor integrated circuit device
Inventor: SHIRAI SEIICHIRO
IPC: H01L21/027
Filed: 1997-03-27
Abstract: PROBLEM TO BE SOLVED: To easily correct the dimension of a resist pattern formed on a semiconductor wafer by making the pattern wider or narrower by irradiating the resist pattern with an electron beam by changing the accelerating voltage of the beam. SOLUTION: After a resist pattern is formed on the surface of a wafer (process 104), the adhesion of the resist film to the wafer and the dry etching resistance of the resist film are improved by baking and drying the resist film (process 105). Then the wafer is inspected for appearance (process 106) and the size of the pattern is measured (process 107). Then the size of the pattern is corrected by making the pattern wider by irradiating the pattern with an electron beam under a low accelerating voltage when the measured pattern is narrower than a specific size or narrower by irradiating the pattern with the electron beam under a high accelerating voltage when the measured pattern is wider than the specific size (process 108). When the size of the pattern meets the specific size, alignment inspections are carried out (process 109).  Therefore, the accuracy of the resist pattern can be improved by easily correcting the size of the pattern.

The slider is moved to a portion having numerous small holes 17 as a part of the molten liquid 16 remains on the substrate 14. Cooling is started to cause epitaxial growth to produce an N- type GaP-layer. When a prescribed temperature is reached, the cooling is once stopped and N atoms are added into a solution. The cooling is thereafter resumed to grow a GaP-layer of low donor concentration. When a prescribed temperature is reached after that, the cooling is stopped and a vaporized impurity source 19 of Zn is heated to produce a P-type GaP-layer on the N-type GaP-layer.
