摘要:
There is provided a ferrule which has a fiber fixed hole into which an optical fiber can be inserted easily without being broken and which can provide a sufficient fiber bonding strength, and which can restrain variations in connection loss caused by the temperature variations.A ferrule 10 is provided with two alignment pin holes 10a into which alignment pins for positioning with respect to a mating ferrule are inserted, and a plurality of fiber fixed holes H formed at predetermined intervals between the alignment pin holes to insert optical fibers. Each of the fiber fixed holes H has at least a fiber guide hole 10d for guiding the optical fiber, a fiber hole 10c connected with the fiber guide hole to accommodate the tip end of the optical fiber, and a fiber insertion hole 10e connected with the fiber guide hole 10d to introduce the optical fiber into the ferrule. A connecting portion of the fiber guide hole 10d and the fiber insertion hole 10e is formed into a taper shape. And the fiber insertion hole 10e is formed so as to introduce the sheathed portion of individual optical fiber.

A high pressure fuel pump for an internal combustion engine having a cylinder, a plunger slidably fitted in the cylinder and a seal mechanism for blocking fuel leakage from an end of a sliding portion between the cylinder and the plunger and also for preventing an lubricant for a driving mechanism of the plunger from entering into the cylinder from the end of the sliding portion of the cylinder and the plunger. A holder surrounding the end of the sliding portion of the cylinder and the plunger is provided. The seal mechanism comprises two mutually independent seal devices mounted with a specific spacing in a longitudinal direction from the end of the sliding portion of the cylinder and the plunger along a circumference of the plunger. The two seal devices are held on the circumference of the plunger by the holder surrounding the end of the sliding portion of the cylinder and the plunger while keeping the specific spacing.

摘要:
It is an object of the present invention to provide a cooking stove that prevents the execution of a process such as ignition of a burner when a touch switch changes from a non-sensing state to a sensing state owing to a factor different from the user's operation. In STEP201, when a first touch switch, which is one of the touch switches provided in an operation portion, is turned on from off, the process advances to STEP202, where a controller provided in a cooking stove main body starts a 1-second timer. The controller executes a loop composed of STEP203 and STEP210. When a second touch switch, which is one of the touch switches and is different from the first touch switch, is turned on from off in STEP210 before the 1-second timer times up in STEP203, the process advances from STEP210 to STEP211. The controller performs “error reporting” by blinking a display portion and activating a buzzer.
摘要:
Disclosed herein is a fuel pump for an inter-cylinder direct fuel injection apparatus, in which occurrence of corrosion and attrition caused by cavitation or erosion can be suppressed, their resistance against the environment can be improved, and an excellent lifetime can be achieved in the case of the use of an aluminum material even if the temperature reaches as high as 100° C. or higher and the pressure reaches as high as 7 to 12 MPa. In the fuel pump for an inter-cylinder direct fuel injection apparatus, made of aluminum or an aluminum alloy, a coating film plated with Ni—P or a Ni—P based material is formed by electroless plating.
