Title: Float valve device
Inventor: MATSUNAGA SHIYOUICHI
IPC: F16K31/26
Filed: 1984-03-05
Abstract: PURPOSE:To automatically close a valve when a float or the like is dislocated by any possibility, by providing in a cylinder a pressure receiving member, which receives the primary side pressure, in a side urging a valve unit in its closing direction. CONSTITUTION:A valve shaft 15 is connected to an arm mechanism 16, and this arm mechanism 16, equipping a series of link mechanisms and an arm 17, is constituted so as to drive a valve unit 14 to be opened and closed. A piston 22, slidably inserted into a primary chamber 11, is connected to the valve unit 14 through the valve shaft 15. A chamber in one side of the piston 22 communicates with a delivery port 12 through a communication hole 23 formed in the valve shaft 14. Accordingly, a valve device, in which the pressure in the primary chamber 11 acts on the other side of the piston 22, is constituted so as to urge the valve unit 14 toward its closing direction by this pressure.

Title: Optical fiber laser apparatus
Inventor: YASUO HIROYUKI
IPC: H01S3/06
Filed: 1994-02-16
Abstract: PURPOSE:To provide a high efficiency optical fiber laser corresponding to change of environment under the optimum condition without using an expensive dielectric material mirror. CONSTITUTION:Both ends of an optical fiber 1 having the amplifying effect are connected with the ports A, C provided opposed with each other of a 2-input 2-direction bothway optical switch 4 to provide outputs from the other ports B, D. An excitation beam is applied to a fiber 1 from a combiner 3. Since a coupling coefficient of ports can be adjusted freely with an application voltage of the optical switch 4, when the ports A and C are disconnected, inverted distribution increases with the excitation beam and when the ports A and C are coupled in a constant ratio, the laser is oscillated continuously. Therefore, when the ports A and C are disconnected for a greater period to increase inverted distribution and these are connected momentarily, an intensive pulse beam is outputted through the Q switching. Therefore, when an accoustooptical switch is used as an optical switch 4, the oth transmitting laser beam is outputted effectively. Even when a reflection mirror is unnecessary and the environmental condition changes, the optimum operation can always be maintained by adjusting the coupling coefficient of an optical switch. A more economical optical switch may be used with a less driving voltage.

IPC: H02P29/00
Filed: 1983-03-16
Abstract: PURPOSE:To perform the acceleration/deceleration control of a servo motor with a small change of speed and a small delay with high responsiveness, by transmitting a position command signal to a servo control part via an LPF of >=2 orders. CONSTITUTION:An acceleration/deceleration control part 5 receives a rectangular wave-shaped position command signal Pa (V0) and converts it into a trapezoidal signal Pb (V1) having tilted rise and fall parts through a rectilinear acceleration/deceleration part 3. Then the signal Pb (V1) is transmitted through an LPF4 to obtain a signal Pc (V2) having slower tilts at the rise start part, the rise end part, the fall start part and the fall end part respectively. The servo control part 6 drives a servo motor M with the output Pc (V2) of the part 5, and therefore the high frequency component is cut to ensure an accurate control with quick response. A vessel type filter is suited to the LPF4, and other types of filters are also available. The part 3 can be omitted to use only the LPF4.
