Abstract: PURPOSE:To simplify constitution by providing a passage selecting means in a communication path which connects a delivery direction-selectable fluid pressure pump to a propulsion machine up-down turning cylinder device. CONSTITUTION:When a manual lever 50 is placed in a low speed position suited for trim adjustment, a delivery direction-selectable fluid pressure pump 24 allows its delivery fluid to flow into a cylinder device 13 from a delivery port 26A or 26B through a check valve 33 or 34 in an opening and closing device 28 and through a pipe line 30 or 31, performing trim up or trim down. On the contrary, when the manual lever 50 is selected to a high speed side, the upper chamber side pipe line 30 is cut off, and the upper chamber side pipe line 30 of the cylinder 13 communicates with a bypass pipe line 49. A pressure of fluid from the tilt up side delivery port 26B of the fluid pressure pump 24 acts on both upper and lower chambers 19, 20 of the cylinder device 13 extended by a differential pressure receiving area of a piston performing tilt up. Thus, a structure can be simplified.

Title: Plate material printing device
Inventor: OKUTSU KOICHI
IPC: G03F7/20
Filed: 1989-10-01
Abstract: PURPOSE:To impart tension to a negative sheet and to offer a plate material printing device which develops no wrinkles and color slurring by stretching the negative sheet in the direction of a negative frame after the end of the negative sheet is supported on a supporting member. CONSTITUTION:The negative sheet to which a negative film is applied is supported to the negative frame 194 with a pin bar 210 and the pin 214 of a pin bar 212. Under this condition, a pair of air cylinders 250 is operated, and a pressure roller 252 is pressed inside the negative frame 194 and is moved to a pressure member 256. Consequently, one edge of the negative sheet is surely supported to the negative frame 194. Under this condition, an air cylinder 242 is operated, and the negative sheet is stretched to impart tension. At this time, the pin bar 210 supporting the one edge of the negative sheet becomes movable in the width direction of the negative sheet and rockable around a shaft member, and therefore the negative sheet does not receive twist and other types of force when tension is imparted thereto. As a result, the negative sheet is never wrinkled.

Filed: 1991-10-04
Abstract: PURPOSE:To accurately measure the flow rate of a fluid by using a corrected pulse signal by performing temperature correction on a pulse signal inputted from a rotating speed detecting device based on a signal inputted from a temperature detecting device. CONSTITUTION:A rotating speed detecting device 8 provided with a magnetic reluctance element 8a, permanent magnet 8b, and rotating speed detection circuit 8c is installed to the outer periphery of a body 1 where an impeller 2 made of a magnetic material is positioned. In addition, a temperature detector 9 which detects the temperature of a fluid is liquid-tightly installed to the body 1 on the upstream side of the body 1. The signals of the detector 9 and detecting device 8 are sent to an arithmetic means 10 in which temperature correcting values for the temperature and flow rate of a liquid and relational expressions between the number of pulses and flow rates are stored in advance. Since the number of pulses are directly proportional to the flow rate, the relevant flow rate can be easily read out from the stored number of pulses when the number of pulses in a fixed period of time is measured and stored.
