Title: Apparatus and method for washing sheet-like article
Inventor: NOZAKI SEIJI
IPC: B08B11/00
Filed: 1996-07-25
Abstract: PROBLEM TO BE SOLVED: To prevent unevenness of washing from occurring by rotating spray heads of shower sprays for washing water in the horizontal direction from a sheet-like article in such a way that spray patterns are overlapped in an apparatus for washing the sheet-like article comprising a carrying device, a high pressure shower device and a water extracting device. SOLUTION: When a sheet-like article 6 used at construction site is washed, at first, the sheet-like article 6 is pinched by a clamping part and a clamp connecting rod of a clamping device at the entrance of a washing apparatus and it is carried to a high pressure shower device 4 by rotating a chain 1. In this shower device 4, a plurality of nozzles 20 are respectively arranged on the top side and the underside nozzle headers 16 and 17 intersecting at right angles to the forwarding direction of the sheet-like article 6. By rotating eccentrically both nozzle headers 16 and 17 in the horizontal direction by means of an eccentric crank 21, approximately elliptical spray patterns are overlapped to unify amt. of washing water and to prevent unevenness of washing from occurring.  Then, washed sheet is transferred to a water extracting device, where water extraction is performed by air blowing and sucking by suction.

Title: Reduction of head loss in manhole
Inventor: MURAKAMI TAKAO
IPC: E02D29/12
Filed: 1990-08-27
Abstract: PURPOSE:To reduce the head loss with prevention of the eddy current in a manhole, by passing most of inflow water in a surcharging state through a rectifying cover. CONSTITUTION:A semi-cylindrical rectifying cover 5 is placed almost in the center of an invert. This rectifying cover 5 made of such material as stainless steel is fixed at the invert by anchor bolts or the like. Most of inflow water fed in the invert of such a manhole 1 in a surcharging state through an inflow pipe 3 pass through within the rectifying cover 5 to discharge to an outlet pipe 4. In this way, the inflow water does not bring about an eddy current in the manhole 1 due to the flushing water at the outlet wall 2. This condition can be kept stable even when the water source within the manhole 1 is increased and the rectifying cover 5 is submerged deep.

Filed: 1984-10-26
Abstract: PURPOSE:To provide a pseudo transfer seen from the CPU without performing an actual transfer of data by connecting a setting register that accepts the optional setting of addresses by a program to the I/O device in addition to the setting switch. CONSTITUTION:1X000111 is set in the setting register of block A, and 1X000000 is set in the setting register of block B (not shown in the figure), then the most significant bits (MSBs) of the both registers of the blocks A and B become 1 respectively. A switching circuit 5 turns to position-B to transfer the content of setting of the register 4 to a comparing circuit 6. In the circuit 6, the data transferred from the switching circuit 5 becomes 000111 in the block-A side, and 000000 in the block-B side. Therefore, as seen from a CPU 1, the setting of the data above in the setting register 4 makes the block A turn to be the block B, and inversely, makes the block B turn to be the block A, by which the processing of the system is able to processed to next process assuming that the data exchange has been performed which actually is not done.

IPC: B41J2/525
Filed: 1998-08-11
Abstract: PROBLEM TO BE SOLVED: To provide a method for processing print information for color printing with which a color adjustment can be carried out sufficiently. SOLUTION: The method for processing print information for color printing includes a first step in which a desired print information is analyzed, rasterized, converted in color to an RGB color system and then to a CMY color system, thereby obtaining data converted to the CMY color system, and a second step in which the color converted data is processed in gradation. In the rasterization in the first step, a plot judgment flag for judging an object to be plotted is added to each bit, so that the color conversion is carried out on the basis of the plot judgment flag. In the second step, the gradation process is performed on the basis of the plot judgment flag. Accordingly, in correcting colors in multicolor printing, the colors can be adjusted sufficiently separately for a character plot part and an image part.

Title: Gas laser equipment
Inventor: MORIGUCHI AKIRA
IPC: H01S3/07
Filed: 1987-09-10
Abstract: PURPOSE:To stabilize laser output characteristics, and decrease a power supply voltage at the starting time of discharge, by connecting coils between each pair of metal electrodes and an AC power supply, and setting the inductance of each coil in the manner in which the combined absolute value of the reac tance of each coil and the reactance between each pair of metal electrodes are made almost equal before and after the discharge. CONSTITUTION:Reactance of each coil 11 is set as omegaL. Reactances between each pair of metal electrodes 3, 4 are set as 1/omegaC0 (before discharge) and 1/omegaC (after discharge). Combined reactances of them are X0 (before discharge) and X (after discharge), whose absolute values are set to be almost equal with each other before and after discharge. Before discharge, the reactance between each pair of metal electrode 3, 4 is comparatively large. In this case, since each coil 11 is connected between each pair of metal electrodes 3, 4 and an AC power supply 8, the combined reactance X0 becomes a resistance of a series circuit of the pair of metal electrodes 3, 4 and the coil 11. When discharge is started between the pair of metal electrodes 3, 4 in the above state, a power supply voltage V necessary to make a specific discharge current I flow becomes small.
