Title: Microwave oven control system
Inventor: MURAKAMI NOBUO
IPC: F24C7/02
Filed: 1991-01-29
Abstract: A microwave oven is provided with a microcomputer that uses individual or total weight and the number of eg. potatoes to determine cooking time. Operating times are calculated for both a microwave generator and also a second conventional heater such as a hot air supplier and/or a direct heater, respectively. Accordingly, the microwave generator, the hot air supplier and/or the direct heater are operated during each determined time so as to make the potatoes soft inside and moderately burnt on the peels. The oven may incorporate a weighing apparatus 4 and has an input panel 5,6 which allows input of potato size (or average potato size) and number of potatoes. Total weight and number may be input in a panel of different design (Fig 5). A third embodiment (Fig 9) has a numerical keypad. Here, the weight of each successive potato is keyed in, whereupon the control system calculates total weight and number of potatoes. <IMAGE>

Filed: 1992-05-01
Abstract: A residual current operated device (10) comprises means (24, 26) for sensing an imbalance between currents flowing in line and neutral conductors (12, 14) between an a.c. source (18) and a load (20), comparators (46, 48, 66) coupled to the sensing means and arranged to provide a control signal (66c) if the magnitude of said imbalance exceeds a predetermined value in either direction, and a gated oscillator (75) responsive to the control signal to provide pulses at a frequency substantially lower than that of the a.c. source, e.g. at about 1 Hz for a 50 Hz supply for causing a thyristor (74) to actuate the switch (22). Under certain conditions, such as reversal of the line and neutral connections to the device, when the device would otherwise be activated at the supply frequency, the reduced frequency may avoid destruction of the thyristor and/or the switch, and warn the user. The gated oscillator comprises potential divider (77, 77a) cooperating with positive feedback resistor (79) to form the non-inverting input of op-amp (75), the inverting input of which is coupled via a resistor to a reference potential and via series connected resistor (79a) and diode (82) to the op-amp output.

Abstract: The seat slide device suitable for a vehicle seat, includes a pair of guide rails 21, 22 for slidably supporting a seat such that the position of the seat relative to a floor is adjustable forwards and backwards. A drive motor 80 causes a relative sliding movement of the rails 21, 22 via a driving mechanism including a gear box 40, fixed to one rail (22), to serve as a reduction gear transmitting torque from the motor 80 to a screw-threaded shaft 31 which is fixed onto the one rail (22) and engaged with a nut member 32 rigidly mounted on the other rail (21) for rotation relative to the screw-threaded shaft, while reducing rotation speed and increasing torque. One or more motor mounting brackets 41, integral with the gear box 40, directly mount the motor on the gear box. One or more apertures 27, 27a in the side wall of the one rail (22) prevent interference between the motor 80 and the guide rail. <IMAGE>

Title: Method and apparatus for detecting hydrogen-containing compounds
Inventor: MCNEIL JAMES A
IPC: G01T7/04
Filed: 1993-08-06
Abstract: A low-cost detector of hydrogen-containing compounds in gas or thin-film samples (10) is disclosed. The device preferably includes an alpha particle source (1), an energy degrading medium (13), a charged particle detector (e.g. a solid state diode detector) (7), and amplification (16), threshold (19), logic (22), timing (25) circuits, humidity correction apparatus (28), and alarm/display circuit (31). The invention relies upon the use of the energy degrading foil (13) to pass selectively certain particles. Energetic alpha particles from a radioactive source (1) enter the sample (10) and hydrogen nuclei, or protons, elastically scattered by alpha particles, are able to penetrate the energy degrading foil (13) which is thick enough to stop the alpha particles (4). The protons are detected and a suitable output signal can be produced to provide an accurate measure of the quantity of hydrogen in the gas or thin-film sample. The hydrogen detector can be combined with a smoke detector to produce an apparatus capable of detecting both smoke and hydrogen. This technology can also be used to reduce noise and block light penetration in a radon detection application.

Patent GB-936152-A (GB)
Abstract: 936,152. Electric measuring instruments. PHILIPS ELECTRICAL INDUSTRIES Ltd. April 20, 1960 [April 23, 1959], No. 13835/60. Class 37. [Also in Group XXXVIII] A mirror galvanometer operates on the principle of keeping the light spot stationary and moving the scale and provides means for projecting an image of that part of the scale giving the correct indication of the quantity measured on to the same screen as the light spot, so that the light spot will lie on that point of the scale indicating the measured quantity. In the embodiment shown in Fig. 1, two mirrors S 1 , S 2 are carried, at a fixed angle to one another, on the moving shaft of the galvanometer coil Sp, and a curved mirror So has a scale provided on it. The arrangement is as follows: light from a source G passes through lenses L 1 , L 2 , is reflected off mirrors S 1  So and S 2  and through lens L 3  on to a frosted glass plate P, so that when coil Sp is deflected by a current passing through it, the light spot from source G will remain stationary, due to the double reflection off the mirrors S 1 , S 2 ; but that point of the scale projected as an image on to plate P will vary in accordance with the deflection of the shaft and therefore with the current in coil Sp. In an alternative arrangement (Fig. 2), only one mirror S 5  is provided on the shaft, and the light from G passes through a lens L 1 , a semitransparent mirror S 3 , through lens L 2  on to mirror S 5 , on to curved mirror So and back from So to S 5 , through lens L 2 , on to mirror S 3  and on to the plate P. In yet another embodiment (Fig. 3, not shown) two mirrors are again provided on the galvanometer shaft, and two curved mirrors, one having half the radius of curvature of the other and having the scale provided on the outside, convex, surface thereof, this mirror being arranged concentrically with the other mirror. The device may be used as a digital measuring instrument by the provision of transparent lines, separated by light screening parts, on the surface P, the distances of the lines differing from the scale lines, so that when the system is deflected, a pair of photo-electric elements at right angles arranged behind P will produce pulse sequencies having a phase difference which is fed to a counter, the count thereon varying with the phase. Alternatively, the distances between the scale lines of surface P and scale on So may be equal but the lines at an angle to each other, so that a moire pattern is produced behind the surface P. The zones move during movement of the coil system in the direction of the line, the direction of movement depending on the sense of rotation of the moving coil. The photo-electric elements must be relatively displaced in the direction of the lines.
