Title: Crawling navigational device of ship
Inventor: TAKAYANAGI KIYOTADA
IPC: B63H21/21
Filed: 1984-02-03
Abstract: PURPOSE:To reliably cut off an external operation means when a hydraulic clutch is turned off and prevent the induced rotation by providing a forced shift mechanism in which the land sections at both ends of a piston close an oil inlet hole and open a drain hole at the operation termination. CONSTITUTION:As an operation lever 27 is rotated in the S direction, a piston 22 is also rotated in the same direction together with a cylinder 21, thereby the elastic force of a spring 26 is weakened gradually, and the oil pressure of an oil outlet hole 210 is reduced. Immediately before the operation termination in the S direction, the piston 22 hits the lug 28 of a decompression adjusting valve 7 provided facing a land section 23 and is prevented from moving to the left, and when the lever 27 is further rotated in the S direction forcibly, the cylinder 21 and piston 22 are relatively moved forcibly. An oil inlet hole 21i is fully closed by the land section 23, and a drain hole 21d is released from a land section 24 and is fully opened to drain the operating oil. Accordingly, the oil pressure of the outlet hole 210 becomes zero, and the clutch plate of a hydraulic clutch is never induced to rotate by the remaining pressure at the termination in the S direction of the lever 27.

Title: Cabin lift controller of cabin lifting hydraulic crane vehicle and control method
Inventor: YAMADA MITSUNOBU
IPC: B66C13/54
Filed: 1996-01-09
Abstract: PROBLEM TO BE SOLVED: To improve the safety during running in a condition in which a cabin is lifted by providing a lock sensor which detects that the cabin is locked at a descent end by a lock pin, a cabin lower limit device which detects that the cabin is at the descent end, and a controller for outputting alarm signal. SOLUTION: A cabin lower limit detector attached on an upper part support frame base 62 detects that a cabin 4 is at a position other than a descent end. Moreover, even if the cabin is at the descent end, a lock sensor which detects in and out of a lock pin into a hole by the operation of a lock pin lever detects that the cabin is in unlocked condition. When the cabin is at least at either of these positions and a mode at which a cabin lift type hydraulic crane vehicle 10 can rise (for example, running mode, mode at which running and work can be done simultaneously) is selected, a controller gives an alarm through alarm means. Consequently, a worker is informed that the cabin 4 runs in an unstable condition to attract his/her attention.

Abstract: PURPOSE:To obtain an improved optical moisture meter with a smaller size and a higher reliability, by arranging a light source for irradiating a sample with light and a light distributor for distributing reflected light therefrom. CONSTITUTION:Light from a light source 10 is made to irradiate a sample 11 via a wide-band filter 35 and the reflected light thereof is distributed into two parts with a light distributor 36 to be converted into electrical signals R and V with respective detectors 39 via a reference signal filter 37 and a measuring signal filter 38. A change portion with respect to the temperature of the sensors 39 previously stored into a CPU33 is received as temperature data of a temperature controller 18 to perform a correction processing of different detection levels of the sensor 39. A level setter 30 is controlled by an output signal of the CPU33 processed by a signal R value to be set to such a level as to let an A/D conversion and a data processing of the CPU33 be in a measurable range. Thus, a reference signal R value and a measuring signal V value are inputted N times to determine an average measuring signal level and an average reference signal level with the CPU33. Thus, a moisture value is calculated by a specified formula to be displayed in analog manner on a meter 25.

Filed: 1986-01-29
Abstract: PURPOSE:To easily and accurately measure the defocus extent of an image pickup element at a laboratory level by projecting a test chart on an image picking up surface for an image pickup element and shifting finely the relative position of the reference surface and the image pickup element in an optical axis direction. CONSTITUTION:At a flange focus distance L from a reference surface 8 of an optical projecting device 7 to the image picking up surface 6 for the image pickup element, the output video signal comes to be a maximum amplitude A as shown in the figure. As the signal leaves from the position to the optical axis direction, namely, as the dislocation of a focus comes to be large, a measuring amplitude B comes to be small as shown in the figure. In such a way, by utilizing that when the focus is dislocated, measuring amplitude B/maximum amplitude A comes to be small, the defocus extent can be quantitatively measured while a rotary knob is turned, an image pickup element 5 is shifted finely, supervised by a displaying device and the scale of a scale plate 20 is read by a pointer 21.
