Title: High-frequency heating apparatus inhibited from operating at maximum power for longer than a predetermined time
Inventor: HORINOUCHI ATSUSHI
IPC: H05B6/68
Filed: 1990-07-31
Abstract: In a microwave oven having a fan 8 to cool a magnetron 5, high-tension transformer 6 and capacitor 7, a keyboard 11 has keys (15) to (19), (Fig 3), to select various power levels below the maximum power which is used in a quick heating mode set by a key (14), and a control 22 prevents operation at maximum power for more than a predetermined time. The oven may be prevented from starting if the maximum power time selected by keys (20) is greater than the predetermined time, or cooling at maximum power may be terminated at the end of that time. The keys (15) to (20) enable cooking in a plurality of stages to be selected, eg. 5 minutes at 450W, then 15 minutes at 300W. However, the oven is inhibited if maximum power is selected for one of the stages. In a second embodiment, (Figs 9, 10), the maximum power predetermined time is automatically adjusted in dependence on the duration of the proceeding cooking operation, on the pause period since the end of that operation, and preferably also on the power level used in that operation. <IMAGE>

Title: Fluid filled dampers, adjusting stiffness
Inventor: JONES HUW
IPC: F16F9/342
Filed: 1990-12-13
Abstract: A damper has a barrel (1) in which a piston (4) slides. A tubular piston rod (6) contains a needle (15) whose tip (14) co-operates with a seat (13) at the end of a central passage (12) through the piston, and the needle has screw adjustment at the exposed end of the piston rod (Fig 2). The space (23) within the tubular rod (6) communicates via apertures (22) with the chamber (24) surrounding the rod on one side of the piston (4). A non-return valve (17, 18) governs passages (16) through the piston to the other side so that on one stroke all fluid transfer has to be via the central passage (12), when the damper stiffness can be finely controlled by the needle valve at any point of the stroke. On the opposite stroke, the non-return valve (17, 15) is opened and fluid transfer between opposite sides of the piston (4) is relatively free. <IMAGE>

Title: Printed circuit board assembly
Inventor: HARVEY DENNIS
IPC: H05K3/46
Filed: 1992-10-31
Abstract: A printed circuit board assembly (50), comprising a transducer (20), having unwanted mechanical strain sensitivity, and a laminated printed circuit board (60) on which the transducer is mounted flush thereto minimises strain on the transducer due to vibrational distortions in the mounting frame onto which the printed circuit board assembly is mounted. These distortions are minimised by reducing the density of the printed circuit board and thereby raising the frequency of the resonant modes of vibration of the printed circuit board above those of the mounting frame, and also by compliantly mounting the printed circuit board assembly to the mounting frame. Strain on the transducer due to temperature changes is minimised by balancing the materials and thicknesses of the printed circuit board layers (62 - 74), thereby reducing the "bi-metallic strip" effect. The assembly may be a thermal imager including a mechanical chopper. <IMAGE>
