A level shifter 13 is provided for each of SR flip flops F1 constituting a shift register 11. The level shifter 13 increases a voltage of a clock signal CK. This arrangement reduces a distance for transmitting a clock signal whose voltage has been increased, as compared with a construction in which a voltage of a clock signal is increased by a single level shifter and the signal is transmitted to each of the flip flops; consequently, a load capacity of the level shifter can be smaller. Furthermore, each of the level shifters is operated during a pulse output of the previous level shifter 13, and the operation is suspended at the end of the pulse output. Thus, the level shifters 13 can operate only when it is necessary to apply a clock signal CK to the corresponding SR flip flop F1. As a result, even when an amplitude of a clock signal is small, it is possible to reduce power consumption of the shift resister under normal operation.

A shift register circuit includes a plurality of latch circuits connected in series to sequentially transfer a pulse signal ST from one to another, a clock signal line transmitting a clock signal CLK, and a plurality of switching circuits performing electrical connection and disconnection between the clock signal line and the plurality of latch circuits. Upon turning on the shift register, at least one of the switching circuits electrically disconnects at least one of the latch circuits from the clock signal line. During an initialization period immediately after power has been turned on, the frequency of the clock signal CLK is lower than in a normal operation period and gradually increases toward the frequency used in the normal operation period.

A clip for attaching a curtain-shield airbag to a body panel of a vehicle comprises a bushing and a pin. The bushing has a flange with a leg extending therefrom. A bore extends through the flange and into the leg for receiving the pin. Outer surfaces of the leg have engagement pieces with shoulders for coupling the bushing to edge regions of a body panel hole into which the leg is inserted. The pin and the bushing are capable of being coupled in a provisionally fixed condition or a permanently fixed condition. When the pin is partially inserted into the bore, the engagement pieces are permitted to flex inwardly of the bore, but when the pin is fully inserted, such inward flexing is prevented. The flange has a wall that provides a partition between the main airbag unit and the entrance hole of the bore in the flange.

An air bag (11) for a side air bag device capable of reducing the size and weight of the device (M1) while retaining a tension line (L--L) when expanded is mounted on the peripheral edge of a door opening (W) at the inside of a compartment, and is formed into a generally rectangular bag shape for covering the door opening when expanded, while being equipped with a gas inlet (19) for introducing an expanding gas. The air bag is provided with joints (22) jointing an inner side wall (12) and an outer side wall (13) partially so as to form a tension line L--L when expanded. The individual joints (22) are juxtaposed in plurality along the tension line so as to cross the tension line, and are arranged generally at vertically middle portions so as to form one expansion chamber (18) having upper and lower spaces (18a and 18b) for the expanding gas to flow therethrough.

A solid impeller is disclosed having a disk-shaped impeller body having an inlet section extending along the impeller axis of rotation. A plurality of discharge passages extend radially and having inlet and discharge ports. The inlet port has an opening verge face which is oblique to the rotational axis. The solid impeller may also comprise a disk-shaped impeller body having an inlet section extending along the axis of rotation of the impeller and plural discharge passages extending radially. It further has inlet and discharge ports which have a tapered shape so that the section area of the discharge passage is gradually reduced in the outward direction. The thickness of the body is also gradually reduced in the outward direction. The solid impeller may also comprise a cylindrically-shaped center body and plural arms on a peripheral surface of the body. These extend radially in an outward direction from the body and include a discharge passage which extends along a longitudinal direction of the arm.

A digital/analogue converter for converting an input n-bit digital code, where n is an integer greater than one, has an n-bit digital input and an output for connection to a load, and includes: an array of (n−1) switched capacitors; and a switching arrangement. In one example embodiment, the switching arrangement is adapted, in a zeroing phase of operation, to connect a first reference voltage to the first plate of at least one capacitor of the array and to connect a second plate of the at least one capacitor to a voltage that, for at least one value of the input digital code, is different from the first reference voltage and is further adapted, in a decoding phase of operation, to enable, dependent on the value of the input digital code, injection of charge into the at least one capacitor. In one example embodiment, the converter may be a bufferless converter having an output for direct connection to a capacitive load.

An occupying area of a digital system signal line driver circuit in an image display device is large and this hinders the miniaturization of the display device. A memory circuit and a D/A converter circuit in the signal line driver circuit are commonly used for n (“n” is a natural number equal to or larger than 2) signal lines. One horizontal scanning period is divided into n periods and the memory circuit and the D/A converter circuit each perform processing for different signal lines during each of the divided periods. Thus, all the signal lines can be driven. Therefore, the number of memory circuits and the number of D/A converter circuits in the signal line driver circuit can be reduced to one n-th in a conventional case.
