Abstract: PURPOSE:To prevent the occurrence of explosion due to leakage of combustible gas, by a method wherein devices, which are susceptible to leakage of combustion gas, are surrounded with a casing, and leakage of gas in the casing is forcibly exhausted to the outside of a building by means of a gas exhausting device. CONSTITUTION:Devices, such as a strainer 6, an ON-OFF valve 7, a control valve 8, etc., which are located on a line 9 for combustion gas, are surrounded with a casing 14. A forward end opening 16a of a suction pipe 16 of an exhausting device 15 mounted on a lower wall 14b of the casing 14 is open right below the uppermost level of an inclining top wall 14a so that combustible gas, being lighter than the air, can be efficiently caught. A discharge pipe 18, having a forward end opening 18a which faces outside the casing 14 and outside a building, is connected to the gas exhausting device 15. Air introducing ports 20 are respectively located below the casing 14 and a side wall 14c. In this constitution, even if combustible gas leaks through the strainer 6, the ON- OFF valve 7, and the control valve 8, etc., the combustible gas is sucked through the suction pipe 16 by means of the gas exhausting device 15, and is exhausted to the outside of a building through the discharge pipe 18, and this eliminates the possibility of explosion resulting from ignition, and ensures very high safety.

Title: Head gap setting method
Inventor: MATSUOKA EIJI
IPC: B41J25/308
Filed: 1987-04-15
Abstract: PURPOSE:To enable a head gap to be set extremely easily with high accuracy, by setting the head gap through moving a carriage backward by a predetermined measure from the position at which the carriage is stopped when a paper guide comes to press a paper, without using a detecting means such as an encoder. CONSTITUTION:A carrier 4 is moved backward by a moving means 4 in the direction for increasing a gap quantity until it is stopped by a stopping means 22. With a paper set in position, a stepping motor 18 is rotated clockwise to move the carrier 4 forward in the direction for decreasing the gap quantity, until the carrier 4 is stopped when a printing head 12 or a paper guide 13 comes to press the paper. After the carrier is thus stopped, the motor 18 is caused to step out. With the motor 18 in the step-out position, the paper can not be moved because it is clamped between the head 12 or the paper guide 13 and a platen 2. Finally, the carrier 4 is moved backward by again rotating the motor 18 counterclockwise by the number of steps required for obtaining an optimum head gap, for example, 0.3 mm. By this method, the head gap is constantly set with high accuracy, and high-quality printing can be ensured.

IPC: G06T5/00
Filed: 1996-04-15
Abstract: PROBLEM TO BE SOLVED: To provide a shading correction method and an overhead projector by which shading is corrected without adjusting a reference value in a trial and error method. SOLUTION: The projection display device is composed of a signal processing circuit 13, a lamp 14, a cold mirror 15, a liquid crystal display panel 16, a mirror 17 and projection lens 18. A CPU 8 obtains a median of image data obtained from an A/D converter 6 receiving the image of a white board picked up by a camera 5. The ratio of the median to the value of each pixel of image data is calculated for each picture element to obtain shading correction pattern data. A multiplier 11 multiplies image data obtained by reading an original 1 by the camera 5 with the shading correction pattern data for each corresponding pixel element. Thus, the shading can be corrected.

IPC: G05B19/4093
Filed: 1985-04-30
Abstract: PURPOSE:To facilitate discriminating whether a tool use sequence is kept after the change of a process sequence, by checking whether the destination of a working process whose position is changed is between two positions of a prescribed combinational part program or not. CONSTITUTION:Data required for the change of the working process of an already generated combinational part program CP is inputted. The working process having a record number Ri specified in the preceding step is retrieved from all part programs P1-Pm, and record numbers Ri-1 and Ri+1 of working processes before and after the working process are obtained. Positions of records Ri-1 and Ri+1 is the combinational part program CP are obtained. It is checked whether the inputted destination exists between both positions obtained in the second step or not. If the destination does not exist there, the position change of the working process is regarded as improper. If the destination exists there, the position change of the working process is regarded as proper. Thus, it is easily discriminated whether the tool use sequence is kept after the change of the process sequence or not.
