Title: Separate lubrication device for outboard motor
Inventor: MATSUMOTO KUNIYOSHI
IPC: F02B75/00
Filed: 1983-05-23
Abstract: PURPOSE:To enable the smooth reoperation of a pressure supply pump, by placing the halfway part of a pressure supply pipe coupled to the pressure supply pump, below the connected part of a suction pipe to a lubricating oil tank, to prevent air from invading when the level of lubricating oil becomes lower than the pump. CONSTITUTION:A suction pipe 20 is connected to the bottom of a lubricating oil tank 18. A pressure supply pump 19 is provided above the connected part of the suction pipe 20. The halfway part 21A of a pressure supply pipe 21 is located below the connected part of the suction pipe 20 to the tank 18. As a result, even if the oil in the tank 18 is at a level 46A lower than the pump 19, the pressure supply pipe 21 continues to be filled with the lubricating oil up to a level 46B equal to the level 46A, the pumping chamber 19A of the pump 19 is stably immersed in the lubricating oil. For this reason, the pump 19 is kept from racing due to an invasion of air into the pumping chamber 19A.

IPC: G01R31/317
Filed: 1999-03-30
Abstract: PROBLEM TO BE SOLVED: To obtain an expected-value collation system by which an expected value can be collated even when the control signal of a bidirectional terminal cannot be detected. SOLUTION: In this expected-value collation system, an output value reaches an expected-value collation module 3 via a signal line (d) when the bidirectional terminal (c) of a target circuit 1 is changed over to an 'output' A waveform which is generated from an input pattern generator 4 refers to the expected value of the target circuit 1. When the waveform reaches the expected-value collation module 3 via a signal line (b), the expected value can be collated. When the expected value is equal to the output result of the bidirectional terminal (c), a waveform which passes the signal line (d) is equal to the waveform reaching the expected-value collation module 3 via the signal line (b). When the expected value is different from the output waveform, an indefinite value is superposed on the signal line (d) so as to be different from the expected value. As a result, its information is output, and it is found out that a problem exists in the target circuit.

Abstract: PURPOSE:To prevent a range finding frame from deviating owing to power variation by placing an objective part and an ocular part in simultaneous power varying motion without shifting the position of the image formation plane by the objective part at the time of the power variation. CONSTITUTION:This finder optical system has the objective part 1 which has positive refracting power on the whole and a power varying function and the ocular part 2 which has positive refracting power on the whole and a power varying function. Then when the power is varied, the objective part 1 and ocular part 2 are put in simultaneous power varying motion so that the image formation plane 4 by the objective part 1 does not shift in position. Namely, the power is varied by the simultaneous zooming of the power varying lens part 1 and ocular part 2 of the finder optical system, the size of the range finding frame seen in a finder is varied as the power of the ocular part 2 and the size of the range finding frame at the time of the power variation comes close to a range finding area. Consequently, the size of the range finding frame can be varied continuously so that the deviation from the actual range finding area is reducible.
