A bulb socket mounting structure inhibits a bulb socket mounted on a panel from being turned to prevent the bulb socket from unintentionally coming off the panel. The bulb socket mounting structure includes a bulb socket with a fixing flange and a locking piece extending from the fixing flange. The locking piece includes a bending portion extended tangentially off an outer cylindrical surface of the fixing flange with a hook at the end of the bending portion away from the fixing flange. The panel forms an engaging recess at a predetermined position to fixedly engage the hook of the locking piece. A relief groove has an inclined guide surface at the end abutting the engaging recess. When the bulb socket is inserted into a mounting hole formed in the panel, the hook engages the relief guide. From this position, the bulb socket rotates toward a socket locking position. The hook of the locking piece moves along the relief groove without bending the locking piece. Immediately before being engaged with the engaging recess, the hook slides up the inclined guide surface while bending the locking piece. Finally the bending locking piece is restored when the bulb socket enters the socket locking position where the hook engages the engaging recess.

A socket intended to receive and make electrical contact between an electrical unit, such as a wedge based light bulb, and a connector. A core including an inner cylinder is provided with an insertion opening at one end. There is an electrically conductive terminal which includes a unit contact at the distal end within the inner cylinder and adjacent the insertion opening. A connector contact extends from the proximal end of the conductive terminal, remote from the distal end, through a terminal hole in the inner cylinder, out of the interior space, and into a connector receiver. The terminal is provided with contacts to receive the unit, and a wall plate adjacent the inner side wall of the inner cylinder. In addition, there is a shield plate adjacent a proximal end which overlies the terminal hole, thereby preventing entry of molding resin into the interior space where it can impair the integrity of the connection.

An optical fiber array according to the present invention includes an optical coupling end face to be optically coupled to another optical line, and first ends of a plurality of optical fibers are arrayed in the optical coupling end face. The optical fiber array includes a lower plate (3a) having a plurality of V-shaped grooves (4) for positioning the optical fibers exposed from one end of a ribbon part of the optical fibers, and an upper plate (3b) for pressing each optical fiber provided in each V-shaped groove (4) of the lower plate into the positioning groove. A boundary portion between the ribbon part (7) and the optical fibers (1) is fixed between the first and second plates (3a, 3b) by heat resistant adhesive (10), and the optical fibers from the boundary portion to a front end of the array are fixed by solder (6) to achieve hermetic sealing.

A process for producing isopropyl alcohol by hydrating directly propylene and water in the presence of a strong acid solid catalyst which includes feeding continuously propylene, water which is the same as or more than propylene in terms of mole, and a saturated hydrocarbon (propane, butane and the like) to a reactor in which the above solid catalyst is filled or suspended, and carrying out a hydration reaction in the conditions of 50.degree. to 200.degree. C. and 60 to 250 atm while maintaining the concentration of isopropyl alcohol contained in the reaction liquid at 6 to 30 weight %, and then drawing a vapor phase out of the reactor, liquefying a part of thereof by reducing the pressure or cooling to separate vapor components, and refining crude isopropyl alcohol contained in the liquid phase to obtain refined isopropyl alcohol.

A housing structure for coupling and releasing optical modules comprises three housing. A first housing including a distal wall at one end, an opening at the other end, and the opening having a first protrusion part protruding toward inside of the opening. A second housing for receiving and holding an optical module provided in the first housing so as to be slidable. The second housing includes a second protrusion part for engaging with the first protrusion part and the sliding of the second housing being limited by the distal wall of the first housing and the first protrusion part. A third housing for holding an another optical module including holding parts for selectively holding the second housing and a contact part provided at one end of the third housing for touching the second housing. The second housing also includes engaging means for engaging the holding parts of the third housing. In case of coupling the optical modules, the third housing is pushed into the first and second housings, whereby the second housing is pressed by the contact part of the third housing and the second protrusion part of the second housing is displaced across the first protrusion part. In case of releasing the coupling of the optical modules, the third housing is separated from the first and second housings and the second protrusion part of the second housing returns to an initial position thereof over the first protrusion part of the first housing.

This invention aims to efficiently assemble a pressure sensor 10 to a connector for a fuel tank. A connector adapted to be connected to electrical devices for the fuel tank is attached to a base plate 1 which closes an opening in the tank. A connector housing 4 is provided with an accommodating chamber 11 in which the pressure sensor 10 is secured. It is possible to assure to provide a space for a pressure sensor 10 in an existing connector, to prevent an increase in the number of connectors, and to decrease costs.
