Title: Electronic equipment practice
Inventor: TAYLOR KENNETH
IPC: H05K9/00
Filed: 1988-04-08
Abstract: An electrical or electronic equipment cabinet is of metal construction to counter electro-magnetic interference. It contains shelves (32, 33) which support printed circuit boards, (34, 35) and one at least of the shelves has a connector field (38) on an insulating board which is hingeable down to provide access to the boards when the cabinet door is open. In one version the cabinet is made from a single metal (light alloy or mild steel) sheet, folded to define side walls and a back. Top and bottom trays are welded to the bent-round sheet, and the front is closed by a metal door. This construction gives good protection against electro-magnetic interference. Ventilation apertures may be provided in the cabinet. <IMAGE>
Patent GB-2211020-A (GB)
Title: Microprobe mass analyser
Inventor: HUTT KENNETH WEST
IPC: H01J49/16
Filed: 1988-11-03
Abstract: The analyser comprises an energy source for directing energy 10 onto a sample 12, and means 14 for producing a magnetic field which confines material removed from the sample by the energy source, in order to promote equalisation of temperature between ionised and non-ionised material, whereby the number of ions is predictably related to the number of neutrals so that subsequent analysis of the ions enables a reliable analysis of the sample material to be obtained. The energy source may be a pulsed laser, an ion source or an electron beam. When an electron beam is used the removed material is ionised by a laser beam 18 directed parallel to the sample surface such a laser beam 18 may also be used to ionise further the material removed by a first laser beam 10 directed perpendicularly to the sample surface. A continuous or time-varying electric field (22), (24), (Fig. 2) may be used to extract ions from the confined material in a direction (20) perpendicular to both laser beams 10, 18 into a time of flight mass spectrometer. The confining magnetic field may be produced by permanent magnets or by coils 14, energised to produce a bottle field (Fig. 3) or a cusp field (Fig. 4). <IMAGE>

Title: "Velocity-modulation transistor"
Inventor: SAWADA MINORU
IPC: H01L29/775
Filed: 1990-12-20
Abstract: An electron supply layer (2), a quantum well layer (3), a first barrier layer (8), a quantum well layer (9a) and a second barrier layer (10) are formed in that order on a GaAs substrate (1) to obtain a device, and source (11), drain (13) and gate (12) electrodes are provided on the surface of this device. In the above described quantum well layers, the lowest sub-band energies of respective carriers largely differ from each other. Accordingly, one of the above quantum well layers serves as a high-speed channel, and the other serves as a low-speed channel. The change in current value with the application of a gate bias depends on only the speed at which electrons move from the high-speed channel to the low-speed channel. Consequently, a velocity-modulation transistor can be constructed which operates at a substantially high speed. <IMAGE>

Title: Oil-operated tensioner with air bleeding mechanism
Inventor: SUZUKI TADASU
IPC: F16H7/08
Filed: 1993-06-08
Abstract: In an oil-operated tensioner for applying tension to a power-transmitting chain, a ball check valve 33, 63 is positioned above the oil chamber 16, 46, either in the tensioner housing 14, Fig 1, or in the plunger 48, Fig 3. The ball of the check valve can oscillate when air is present in the oil chamber, since air is compressible. Oscillation of the ball, which occurs when the plunger oscillates during operation of the tensioner, allows the residual air to be discharged from the oil chamber. However, after the air is discharged, oscillation of the plunger is restrained by the incompressibility of the oil, and oscillation of the ball is restrained by the viscosity of the oil which then surrounds the ball. The valve seat of the check valve preferably opens upwardly. <IMAGE>
