Title: Control of induction heating apparatus
Inventor: FUKASAWA MINORU
IPC: H02M7/5395
Filed: 1985-02-08
Abstract: Induction heating apparatus includes a digitized control circuit for the ON/OFF control of a switching element which has hitherto utilized an R-C time constant, thereby eliminating the defects, such as a change in the R-C time constant with time and non-stabilization of the heating output accompanied by a temperature change. Since the digitized control circuit can be a monolithic integrated circuit, the apparatus as a whole can be miniaturized and inexpensive to produce. Furthermore, the digitized control circuit provides quick over-current protection, exact detection of unsuitable load, prevention of noise generation, and facility of design corresponding to various power supply voltages. A circuit (17) compares digital values of input current and power setting to provide an input for a counter (21) which determines the duration of closure of a transistor switch in a resonant inverter circuit. <IMAGE>

Title: Method and apparatus for surface diagnostics
Inventor: BECKER CHRISTOPHER H
IPC: H01L21/00
Filed: 1984-09-20
Abstract: Method and apparatus for mass spectral analysis of unknown species of matter present on a surface in extremely low concentrations. A probe beam such as an ion beam, electron beam or laser is directed to the surface under examination to remove a sample of material. An untuned, high-intensity laser is directed to a spatial region proximate to the surface. The laser has sufficient intensity to induce a high degree of nonresonant, and hence non-selective, photoionization of the sample of material within the laser beam. The non-selectively ionized sample is then subjected to mass spectral analysis to determine the nature of the unknown species.

Patent GB-861411-A (GB)
IPC: B27L5/00
Abstract: 861,411. Making veneers. PETERSEN, T. A., WENNHOLTZ, H., and STAUB, A., [trading as BERLINER FURNIERMESSEREI GOOSENS, WENNHOLTZ & CO. KOMM. -GES.]. Dec. 3, 1959 [Dec. 6, 1958], No. 41161/59. Class 145. Veneers are produced by pressing a stack of glued laminations 11 covered on at least the top and bottom faces with relatively thick sections of timber 12, 13 and slicing or rotarypeeling the veneers from the block so produced. The timber sections consolidate the block during handling and cutting and provide a protective edge on the cut veneers but may also be used as part of the veneers if they are of good-quality timber. Where the laminations are of undular form, as shown, the timber sections may be made by cutting along a wavy line through a block of wood and the parallel edges of the block are then more easily accommodated between the flat platens 14 of a press. Where wood wedges are inserted in the block to produce waviness, the timber sections can be cut at the appropriate angle to give parallel edges. The blocks may be held together by steel bands or cramps while the glue is setting and these may be left in place while the block is steamed, or immersed in water prior to steaming, before cutting takes place. Covering sections may be glued on additional faces of the laminations to give further protection and to allow the clamped blocks to be sliced practically from end to end.
