IPC: G02F2/02
Filed: 1993-12-28
Abstract: PURPOSE:To stabilize an optical pulse signal by reducing the polarized wave dependency of an optical frequency shifter repeatedly generating the optical pulse signal. CONSTITUTION:An optical signal 103a outputted from the optical frequency shifter 102 is made incident on an etalon filter 104, and a signal 104a of the second half part in one period is taken out. Then, a certain pulse in the signal 104a is extracted by a signal extraction circuit 107 to be outputted as the signal 107a. The signal 107a is compared with a reference signal of a reference power source 108 in a level comparator 109, and a difference signal showing the difference is supplied to an operation circuit 110. In the operation circuit 110, a control signal according to the difference signal is generated, and a current flowing through a Faraday rotator 102g is controlled by a drive circuit 111 based on the control signal, and the polarized wave angle of the optical frequency shifter 102 is controlled.

IPC: F04B9/04
Filed: 1996-12-19
Abstract: PROBLEM TO BE SOLVED: To reduce the power loss of a plunger pump and the wear of its cylinder and plunger by reducing the side force that its pump cam exerts on the plunger. SOLUTION: A plunger 15 is formed at its lower end with a semispherical face 22 of which center O is situated on the center axis P thereof. A shoe 26 contacting with a pump cam 8 is famed with a semispherical concave 27 adapted to slidably engage with the semispherical face 22.

Title: Friendly self-expanding capture net for high-speed territorial water invading ship, friendly strategy and underwater self-expanding defense net capable of setting retaining depth
Inventor: ONODERA SATOSHI
IPC: B63G13/00
Filed: 1999-10-26
Abstract: PROBLEM TO BE SOLVED: To humanely or friendlily capture an illegal high-speed territorial water violating ship by use of strategy and a means having no killing and wounding performance. SOLUTION: This rolled self-expanding capture net 1 is thrown down ahead of a course of the high-speed territorial water violating ship from an air carrier means to cause self-expansion of the net 1. Simultaneously with the self- expansion of the net 1, buoyant lock ropes 2 vertically rise toward the water surface. When a screw of the territorial water violating ship passes through the lock ropes 2 standing side by side, the lock ropes 2 are caught in a current and led to the screw to twine about the screw. The twining of the several ropes 2 draws a large self-expanding net body. As a result, rotation force of the screw is reduced or the screw is locked and stopped to stop the territorial water violating ship.

Filed: 1993-12-13
Abstract: PURPOSE:To quicken a speed change when a driver is necessitated to perform a quick speed change by detecting a moving speed of a speed change lever at a time of speed change operation and, if the moving speed is high, increasing the air pressure for controlling a pneumatic actuator. CONSTITUTION:A pneumatic shift cylinder 40 is operated through ON/OFF control of solenoid valves 42, 44 by means of a controller 34, which receives detection signals from a lever-position sensor 26, a clutch sensor 28, etc., and a speed change of a transmission 36 is controlled via a push rod. In this case a parallel circuit consisting of, an electromagnetic opening/closing valve 64 and a pressure reducing valve 60 is installed in a pressurized air supply pipe line 56 leading from an air tank 52 to the shift cylinder 40. When the electromagnetic opening/closing valve 64 is closed for an ordinary speed change, the pressure of the pressurized air is reduced by the pressure reducing valve 60 and then sent to the shift cylinder 40. On the other hand, when the electromagnetic opening/closing valve 64 is opened because of quick moving speed of a speed change lever 20, the pressurized air, whose pressure is increased, is sent to the shift cylinder 40, thereby making a quick speed change.

Abstract: PURPOSE:To secure the electric conductivity by making a face for junction with the vibration elastic body of an electrical-mechanical energy conversion element rougher than the junction face of the vibration elastic body. CONSTITUTION:The surface of a copper layer 11 laminated on a nickel layer on a face for junction with the vibration elastic body 7 of an electrostrictive element 10 is made rougher than the junction face of the vibration elastic body 7. A proper quantity of bond dropped at one or more points on the junction face of the vibration elastic body 7 flows evenly into the gaps in the copper layer 11 of the electrostrictive element 10 instead of direct compression bonding of the vibration elastic body 7 to the electrostrictive element 10, forming a uniform bond layer on the whole face without overflow of the bond. Thereby strong bonding is made possible, the copper layer 11 comes into direct contact with the vibration elastic body 7, and the electric conductivity is securely obtained.

Filed: 1989-12-29
Abstract: PURPOSE:To enhance the visibility of a negative film and to prevent the lowering of a light quantity as much as possible by separately constituting a negative carrier and a mirror tunnel so that they can be freely attachable and detachable with each other and fixing a diffusion board on a negative carrier base. CONSTITUTION:The negative carrier 4 and the mirror tunnel 3 are separately constituted, and the exit diffusion board of the mirror tunnel 3 is a transparent board 10, and the diffusion board 11 is fixed under the negative mask of the negative carrier 4. When the negative surface is viewed from an oblique and upward direction, the visibility of the inner side of the negative film 5 can be improved since light is emitted with the same brightness all over the diffusion board 11 just under the negative mask. By such a constitution, a photographic printing device having good operability can be obtained by enhancing the visibility of the negative film from the oblique direction without making the operability in the replacement of the negative carrier and the mirror tunnel worse and without the lowering of the light quantity of the negative surface.
