Title: Etching aluminium alloy and titanium nitride multilayer films
Inventor: KAWAMOTO HIDEAKI
IPC: H01L21/3213
Filed: 1997-05-30
Abstract: A method of fabricating a semiconductor device is characterized in that a mixture gas including chlorine (C1 2 ) gas and boron trichloride (BC1 3 ) gas is employed as an etching gas when a multi-layered film including an aluminum alloy film (3-1Aa) and a titanium nitride film (8a) is etched. The volume ratio of the BC1* small Greek omega * gas to both of the C1* small Greek eta * and BC1* small Greek omega * gases is set to be equal to or greater than 15%. The method can prevent irregularities from being generated on a surface of the titanium nitride film when etched, which in turn can prevent generation of etching residues which may occur due to such irregularities, thereby reducing the probability of a shortcircuit between wiring layers.

Abstract: 989,783. Endless conveyers. WESTERN ELECTRIC CO. Inc. May 30, 1961 [May 31' 1960], No. 19471/61. Heading B8A. In a device for laying (or recovering) a submarine cable 1 from a ship, control of the movement of the cable is effected by the gripping action on the opposite sides thereof by juxtaposed gripping units 3, 4 which have their track formations driven or restrained by sprocket wheels 7. Gripping pressure is applied to the tracks by loading units 8, 9 each of which comprises two air springs 10 mounted in tandem on a spacing member 11. The cable 1 passes over a laod cell 6 which feeds an electrical signal, dependent on the tensile load in the cable, to a computer 36 which processes the signal and applies control signals via cable 38 to servosolenoids 24 controlling the amount of compressed air fed to the loading units 8, 9. Thus the total instantaneous gripping pressure exerted along the mating section of its tracks 3, 4 is varied in accordance with variations in the instantaneous tension in the cable 1. In an alternative embodiment (Fig. 4, not shown) the torque of one of the sprockets 7 is used, by means of a load cell similar to cell 6 above, to provide the control signal. Specifications 734,082 and 924,471 are referred to.

IPC: H02J7/32
Filed: 1999-05-17
Abstract: A direct current power supply has a generator 21, 22, 23 driven by hand or foot compression effort, and energy storage means in the form of a rechargeable battery (26, Fig.2) or capacitor which is charged by the generator. The supply may provide power to a fixed or portable apparatus, such as a remote control transmitter (eg. for a television), a personal computer, a helmet torch, or a mobile telephone. The supply may have a pad 3 biased to a raised position 9 by a spring 8 and movable by heel pressure so as to act via a recirculating ballscrew device 2 which converts linear motion of pad 3 to rotary motion of a nut 4. Rotation of the nut 4 drives the rotor 21 of an alternator via a unidirectional clutch 16 and gears 15, 17. A similar device which is operated by hand pressure may be incorporated in a remote control transmitter (Figs.4-7) and may have a shape, size and connectors (70, 71) which are the same as those of a battery pack which the transmitter is designed to use. An alternative supply allows generation of power whilst walking and has a device (Figs. 8,10) to be attached under the heel of the foot or footwear, and a generator (Figs.9,11) disposed in a remote housing (120). Foot pressure causes linear movements of a cable (112) coupled between the heel-mounted device and the housing (120), and this motion acts via a sector gear (126), a unidirectional clutch (122) and other gears to drive the rotor (144) of an alternator mounted in housing (120) together with a rectifier and a rechargeable battery. A spring (137) is provided to absorb the energy of a rapid foot depression, and to transfer the energy whilst the walking cycle continues.
