An obliquely bent spring tab is projected from a circumference of a bolt hole in a power connector of a bus bar. When the bus bar is housed in and fixed to a case, the spring tab is in stable surface contact with a bolt. Thereby, conductivity inspection can be performed by connecting a conductivity inspection apparatus to the bolt.

An electric junction box for a vehicle is assembled by fitting and locking a connector through an aperture provided in a main case; the aperture being used for fitting the connector that holds a retainer at a temporary latch location, the retainer providing a double latch for a terminal; inserting and latching the terminal of an electric wire into the connector; and pushing the retainer into a full latch position. A recess for retainer operation is provided at a location facing the retainer and on a surrounding wall of the main case that surrounds the aperture.

Upper and lower casings (10, 11) are coupled together and are fixed to a holder (20) by a bolt (B). The upper casing (10) has an upper wall (10b) with a bolt hole (11c) and the lower casing (11) has a bottom wall (11b) with a bolt hole (11c). A cylindrical collar (15) is molded with the bottom wall (11b) of the lower casing (11) and projects from the edge of the bolt hole (11c). The collar (15) has a length to penetrate through the bolt hole (10c) in the upper wall (10b) of the upper casing (10). The collar (15) has a step (15a) for supporting a lower surface of a bolt head (Bb) of the bolt (B) and inward projection (15b) for engaging an upper surface of the bolt head (Bb). Thus, the bolt head (Bb) is held rotatably between the step (15a) and the inward projection (15b).

A carburetor has an apparatus for compensation of idling revolution of an internal combustion engine. The apparatus comprises a bypass passage one end of which is opened to the air suction conduit of the carburetor upstream of a throttle valve, the other end opened to the same downstream of the throttle valve. A fuel passage supplies fuel into the bypass passage to form a fuel-air mixture, a solenoid valve provided on the bypass passage for controlling a quantity of the fuel-air mixture in response to operation of a load such as, for example, heater, a radiator fan, lights, an air conditioner, etc. so that the idling rotational speed to be decreased by such operations is compensated by supplying fuel-air mixture into the air suction conduit.

According to one embodiment, a video display apparatus includes: a broadcast data input module; at least one data input module; and a frequency controller. The broadcast data input module is configured to input broadcast contents containing sound data. The data input module is configured to input information containing sound data other than the sound data contained in the broadcast contents. The frequency controller is configured to receive the sound data, and configured to perform an operation allowing only frequencies within a necessary range to pass therethrough, the operation of the frequency controller being selectively enabled or disabled under control of the data input module.

In a structure for attaching a circuit board terminal to a circuit board, stress is minimized in a soldered portion on a circuit section upon inserting and drawing an electrical element into and from the circuit board. The attaching structure including a holding member mounted on and secured to a circuit board, a bus bar that has a base portion supported on the holding member and a leg portion that passes one or more through-holes and to be soldered on a circuit section, and a circuit board terminal that has a base portion to be connected to the bus bar and a connection portion adapted to be coupled to a terminal of an electrical element. The bus bar is provided on the base portion with elastic tongue pieces that can contact elastically with a circuit board terminal. The circuit board terminal is connected through the bus bar to the circuit section.

Upper and lower casings (10, 11) have the surrounding walls coupled together. A bolt (B) is mounted beforehand in the casings (10, 11), and projects through a bolt hole (11c) in the lower casing (11) to fix the casings (10, 11) to a holder (20). A first bush (15) is fixed in the lower casing (11) and a second bush (16) is interlocked with an outer circumferential surface of the first bush (15). The bolt (B) passes through the bushes (15, 16) so that a lower surface of the bolt head (Ba) engages the upper end surface of the first bush (15). On the other hand, an inward-projection is formed on an upper part of the second bush (16), and contacts the upper surface of the bolt head (Ba). Thus, the bolt head (Ba) is held rotatably between the upper end surface of the first bush (15) and the inward-projection.

An automotive electrical connection box (10) has a casing main body (11) fastened to a holder (20) by a bolt (B). A mating connector (12) is mounted in the casing main body (11) and is connected with a waiting-side connector (21) in the holder (20) simultaneously with the fastening by the bolt (B). A dummy housing (13) projects from the casing main body (11) at a side of the bolt (B) opposite the mating connector (12), and an opening (22) is provided at a portion of the holder (20) corresponding to the dummy housing (13). The dummy housing (13) and the opening (22) engage and create a stress to balance a stress created upon connecting the waiting-side connector (21) and the mating connector (12).
摘要:
A process for producing an unsaturated group-terminated high-molecular weight polyalkylene oxide by adding an alkali metal and/or an alkali metal compound capable of producing an alkali metal hydroxide on reaction with water to a hydroxyl-terminated polyalkylene oxide having a repeating unit represented by formula --R.sup.1 --O-- (wherein R.sup.1 represents a divalent alkylene group having from 2 to 8 carbon atoms) to substitute the hydrogen atom of the hydroxyl end group with an alkali metal (alkoxidation) the resulting polyalkylene oxide is reacted with a polyhalogen compound to increase the molecular weight of the polyalkylene oxide and then additional alkali metal and/or alkali metal compound is added before reacting the resulting high-molecular weight polyalkylene oxide with an unsaturated halogen compound to introduce an unsaturated group to the molecular chain terminals. The first addition of alkali metal and/or alkali metal compound capable of producing an alkali metal hydroxide on reacting with water is added in an amount equivalent to or less than the hydroxyl end groups of said polyalkylene oxide and second addition of alkali metal and/or alkali metal compound is added in an amount equivalent to or greater than the remaining hydroxyl end groups.
