Title: Air-fuel ratio adjustor for gas engine
Inventor: KUBOMOTO ISAMU
IPC: F02D19/02
Filed: 1990-03-16
Abstract: PURPOSE:To improve the startability in a light load region by controlling the flow rate so that the air-fuel ratio increases in the region where the detected load is larger on the basis of the engine load detection signal and reducing the discharge concentration of the nitrogen oxide in a high load region. CONSTITUTION:As for an engine 2 in the region ranging from a no-load state to a light load state, a solenoid valve 39 for bypass is closed, and the intake air quantity supplied from a mixer 9 is reduced, and operation is performed with a small air-fuel ratio. When the load increases and exceeds a prescribed value, also the fuel gas feed quantity exceeds a set value. Then, a fuel gas flow-rate detector 41 detects this increase, and a valve 39 is opened, and then, a large quantity of air flows into the mixer 9 from the air taking-in passage 11, and the engine 2 is operated with a large air-fuel ratio. If operation changes from the high load operation to the light load operation, also the fuel gas feed quantity reduces less than a set value, and the detector 41 detects this state, and the valve 39 is closed, and the engine 2 returns to the operation with the less air-fuel ratio.

Title: Laser beam irradiating apparatus for gas gun
Inventor: IWAZAWA TATSUO
IPC: F41B11/70
Filed: 1999-03-15
Abstract: PROBLEM TO BE SOLVED: To obtain a sense of feeling shooting by using a laser beam together with a gas gun by closing a contact of a switch by a pressure of a gas to energize a laser module, and irradiating the beam corresponding to a trajectory of a bullet. SOLUTION: When switch pieces become a contact state (a), a circuit is closed to allow a current to flow, a laser module 28 is operated, thereby starting irradiating of a laser beam 54. Then, a piston is continuously forwarded, and a gas is soon exhausted from a degassing passage 30. When an elastic force of a spring member overcomes the gas pressure so that the pieces are separated, irradiating of the beam 54 is stopped. Thus, the beam 54 can be irradiated while obtaining a sense of feeling shooting by using the beam together with a gas gun to obtain a shooting range distance which may be of the degree without limit, and a hitting accuracy can be remarkably improved. Accordingly, a remarkable effect can be obtained from a toy gun using a BB bullet to an air rifle for a game.

Title: Processing system for connection between single-mode optical fiber and multi-mode optical fiber
Inventor: HAKOMORI KATSUHIKO
IPC: G02B6/26
Filed: 1988-03-22
Abstract: PURPOSE:To prevent transmission quality from deteriorating by interposing an optical fiber for connection which has a low-refractive index part having a lower refractive index than a core part in the center part of the core part between a single-mode optical fiber and a multi-mode optical fiber, and entering light which is projected from the single-mode optical fiber into the low-refractive-index part. CONSTITUTION:When the single-mode optical fiber 1 and multi-mode optical fiber 2 are connected to each other, the optical fiber 5 for connection which has the low- refractive-index part having the lower refractive index than the core part 3 is interposed in the center part of the core part 3 between both fibers. Then the light which is projected by the single-mode optical fiber 1 is entered into the low-refractive-index part 4 is entered into the low-refractive-index part 4. The projection light of the single- mode optical fiber 1 which is entered the low-refractive-index part 4 is transmitted through the lwo-refractive-index part 4 and entered into the multi-mode optical fiber 2 directly or after being converted into various modes through a high-refractive-index part. Consequently, even if the state of abutting between the fibers at the connection part changes, variation in waveform shape on a reception side is prevented.
