A fuel vapor recovery apparatus has a canister for adsorbing fuel vapor generated in a fuel chamber formed in a fuel tank. A fuel vapor inlet of the canister is connected to the fuel chamber. A fuel vapor outlet of the canister is connected to an intake passage of an internal combustion engine. Fuel vapor adsorbed by the canister is purged therefrom into the intake passage. An air vent of the canister is connected to an air chamber that has a predetermined capacity.

A fixing apparatus for fixing a terminal of a control cable is composed of a fixing member which is provided in a given position of a vehicle such as automobile construction machine, a terminal fixing metal fixture fixed to the terminal of the control cable being engaged with a bracket without substantial play in the axial direction, and is provided for non-detachably fixing the terminal fixing metal fixture from the bracket.
摘要:
A canister for treating fuel vapor generated in a fuel tank and for supplying fuel vapor to an intake system of an engine via a purge passage. First and second adsorbent compartments are defined in a casing by a partition for accommodating adsorbents. First and second dispersion compartments are defined in the casing for dispersing fuel vapor from the fuel tank. The first and the second dispersion compartments are located at one end of the first and second adsorbent compartments, respectively. A valve device is positioned at one side of the second adsorbent compartment for selectively opening and closing in accordance with the difference between internal and external pressures of the casing. A tank valve is connected to one side of the casing corresponding to the first adsorbent compartment for adjusting the pressure in the fuel tank. An external dispersion compartment is connected to a wall of the casing to communicate with the first dispersion compartment. A breather passage is connected to the external dispersion compartment for introducing fuel vapor into the canister from the fuel tank during refueling, and the external dispersion compartment has a cross sectional area larger than that of the breather passage.

According to the present invention, there is provided a fuel reserving device for reserving fuel therein comprising a wall for dividing an interior of the device to a fuel chamber and an air chamber, the wall being deformable according to the amount of the fuel in the fuel chamber, a discharge passage which is open to a space formed above the surface of the fuel in the fuel chamber and a shut off valve for normally shutting the discharge passage off. Gas is discharged from the space via the discharge passage when the shut off valve is open. The shut off valve is opened and the gas is discharged from the space when the amount of the gas is larger than a predetermined amount. On the other hand, the shut off valve is closed and the discharging operation of the gas is stopped when the amount of the gas is smaller than the predetermined amount.

A vehicular foot-operated parking brake control apparatus is designed to achieve reliable and easy operation of the apparatus while also reducing the apparatus size and the stroke loss. The apparatus includes a mounting bracket that is adapted to be fixed to a vehicle body, and a pedal that is rotatably mounted on the bracket for rotation about a rotational axis, with the pedal being connected to a parking brake control cable. The pedal is provided with a plurality of ratchet teeth and a pawl is rotatably mounted on the bracket for rotation between a first rotational position in which the pawl is engaged with the ratchet teeth and a second rotational position in which the pawl is disengaged from the ratchet teeth. The pawl is slidably mounted on the bracket to slide between a first slide position and a second slide position. The apparatus is designed to allow the parking brake to be engaged and disengaged by pressing on the pedal.

Disclosed is a refractory/heat insulating panel used in buildings and structures which must have a refractory performance. In the refractory/heat insulating panel (801), the mechanical strength and the fireproofing performance at the joint portions, which are weak portions in the panel, are increased by integrally forming inorganic boards (831) in the male and female joint portions (832, 836), filling a light-weight aggregate in the core material located at the male and female joint portions at a high density, or making the density of the core material at the joint portions higher than that at the center of the panel. Further, a nonwoven fabric is inserted between a core material (829) and a surfacing material (802) and between the core material (829) and a backing material (822), the surfaces of the surfacing material and the backing material facing the core material are embossed, a layer of isocyanurate foam and/or a layer of polyurethane foam are provided in the core material, or a wooden reinforcing material or a pipe-shaped member is buried in the core material to improve the adhesion between the core material and the surfacing material and between the core material and the backing material, the strength of the entire panel, refractory performance, etc. These structures also increase the strength and the refractory performance of the joint portions.

In a corner reduction device for reducing side corners of a slab with corner rolls, a pair of upper and lower corner rolls are mounted inside a unitary unit frame, and a corner roll unit housing the unitary frame which is movable in the direction of width and vertical direction of the material is formed. Vertical position of the corner roll unit is controlled by a lifting power control cylinder through a push rod and position in direction of material width is controlled by a reduction cylinder. Driving of cylinder servo valves is controlled in accordance with position set values set by position setters, load set values set by load setters, and feedback signals from position sensors, thereby controlling the corner roll positions to fixed lateral and vertical positions. The driving of the servo valves is corrected according to values detected by cylinder pressure sensors, to evenly reduce the right and left corners of the material.

In a sizing press for reducing by pressure width of hot slabs of both a low carbon steel and a stainless steel, the reduction by pressure of width is performed quickly without replacing the dies each time. Two or more types of dies having caliber configurations for respectively reducing the width at least of a low carbon steel and a stainless steel are disposed in layers and are retained in a manner capable of being displaced in an up and down direction. They may be replaced as a block with another block of stacked dies.

In this invention, a back end portion of a preceding sheet bar and a front end of a succeeding sheet bar are cut in a transfer line at an entrance side of a finish rolling mill so that at least both side edge regions of these sheet bars are contacted with each other at a butted contact state thereof and a gap is formed between both end portions and then portions to be joined int he preceding and succeeding sheet bars are locally heated and pushed to join them while gradually enlarging a joining area, whereby the required time is largely reduced as compared with the conventional technique and also it is attempted to miniaturize the heating apparatus and shorten the length of the apparatus.
