Granted: 1998-06-16
Abstract: A method is provided for producing a light emitting device having a chip with a front surface, a rear surface, an electrode formed on the front surface, a narrow emanating region near the front surface, and a spherical lens fixed to the rear surface for converging light beams. The method includes the steps of grinding a rear surface of a wafer until the thickness of the wafer is reduced to a value d2, wherein the d2 is determined from the equation d2=d1-r, wherein d1 is the distance between the centre of the spherical lens and the centre of the emanating region and r is the radius of the spherical lens. Another electrode is formed on the near surface of the wafer in a form which allows light to emanate therethrough. The wafer with a flat rear surface is divided into a plurality of individual device chips, each chip having an emanating region and electrodes. A device chip is mounted on a workpiece at the rear surface of the device chip. A current is supplied to the device chip for emitting light through the rear surface of the device chip. The pattern of the emanating region is observed by a TV camera which is connected to a computer. The centre of the emanating region is determined in a two-dimensional coordinate which is defined on the rear surface of the device chip. The coordinates of the centre of the emanating region is memorized. Adhesive is supplied on the rear surface of the device chip. A spherical lens is carried to a spot of the memorized coordinates above the centre of the emanating region. The adhesive is then hardened to fix the lens on the rear surface of the device chip without a gap between the lens and the rear surface of the device chip.

Abstract: La valve (10) comprend un boîtier (20) muni d'une entrée d'air (23) fixée à l'extrémité d'un conduit d'air vicié (60) d'un appareil ménager, et d'une sortie d'air (24) vers l'extérieur. La valve (10) comprend un épaulement (41) relié hermétiquement à l'entré d'air (23). Une balle (42) logée dans le boîtier (20) s'y déplace entre une première et une deuxième position en suivant un guide (43). Lorsqu'aucun écoulement d'air ne provient du conduit (60), la balle (42) s'appuie hermétiquement et par gravité contre l'épaulement (41) afin de prévenir la pénétration d'air extérieur à l'intérieur du conduit sous l'effet de rafales de vent. L'épaulement (41) et la balle (42) peuvent être faits en un matériau isolant afin de diminuer la perte de chaleur par conduction vers l'extérieur par temps froid. Lorsque l'appareil ménager est en fonction, la balle (42) se déplace à la deuxième position sous l'effet de l'écoulement d'air vicié pour permettre son évacuation. Une fois que l'appareil est arrêté, la balle (42) retourne toute seule à la première position. La valve (10) peut avantageusement s'appliquer à toute sortie d'air forcé que l'on retrouve sur des appareils, tels les sorties d'air de sécheuses, de ventilateurs de chambre de toilette, d'échangeurs d'air ou de hottes de cuisinière, afin de remplacer les clapets pivotants conventionnels.

Granted: 1998-07-14
Abstract: An extended frame memory is provided in parallel with a frame memory, and tomographic images having a number required for computing the cubage of a part to be ultrasonically scanned, are beforehand stored in the extended frame memory.  Thereafter, the thus stored tomographic images are successively read out, and sectional areas are computed from the stored tomographic images.  Then, the cubage of the part to be ultrasonically scanned of an examinee is calculated from the thus computed sectional areas.  The computation of the cubage is conducted after the tomographic images having a number required for the computation of the cubage are stored in the extended frame memory, thereby it is possible to reduce the burden to the examinee.

Patent CA-2121563-C (CA)
Inventor: BASAK ARUN K
IPC: B01J8/00
Filed: 1994-04-18
Granted: 1999-03-30
Abstract: Separation of a high temperature (e.g. 300-1200°C) and high pressure (e.g. 2-20 bar) solids-gas stream from a pressurized fluidized bed reactor into solids and gas while reducing the pressure of both the gas and solids takes place in a vertical de-entrainment vessel having a packed bed of solids within it.  The possibility of fluidization of the solids is minimized by causing the velocity of the gas component of the solids-gas stream to be reduced during, or just prior to, introduction of the gas into the packed bed of solids, e. g. by providing an expanding conical end to the inlet for the solids-gas stream into the vessel.  A gas permeable solids impermeable element may also or alternatively be connected to the inlet and extend toward (optionally all the way to) the side wall of the vessel, to substantially prevent fluidization.  The fluidization-preventing element may be a perforated plate, ceramic filter, or wire mesh screen, and may have gradually increasing gas permeability from the inlet to the vessel side wall.  A number of different inlet flows to the vessel may be provided, and at least one separated gas and solids outlets leads from the vessel to a low (e. g. atmospheric) pressure area.

Title: Method of controlling a photoreaction with a laser beam
Inventor: KIRA MITSUO
IPC: C07F7/18
Filed: 1994-12-07
Granted: 2004-04-20
Abstract: A target is irradiated with a laser beam having an energy of h ~/n, where n is an integer, instead of the photon energy h ~ required for a reaction to proceed using a conventional single-photon excitation method. A desired reaction is selectively induced by the absorption of multiple photons instead of single photons. It is thus possible to induce a photoreaction in which an absorption is carried out in accordance with a selection theory different from that of single-photon absorption, and which is quite different from a photoreaction induced by a single-photon excitation. Namely, a target or reactant is irradiated with a photon energy h ~2 having a wavelength integral times longer than that of the photon energy h ~1 necessary for a photoreaction to proceed. Photon energy h ~2 is either used in place of the photon energy h ~1 necessary for a photoreaction, or together with the photon energy h ~1, to thereby make the reactant absorb the energy equal to the photon energy h ~1, The method is capable of selectively and preferentially inducing a specific photoreaction among various possible, concurrent photoreactions.

Abstract: A method of installing a liner in a dry parent tube of a heat exchanger includes inserting a continuous tubular liner into the parent tube, sealing one end of the continuous tubular liner and sealingly attaching the other end to a source of pressurized fluid and injecting fluid under pressure into the continuous tubular liner to hydraulically expand the tubular liner substantially into contact with the parent tube. The interior of the parent tube may be cleaned beforehand, preferably to a white metal finish. Opposed ends of the continuous tubular liner are milled to conform to the opposed ends of the parent tube, and the opposed ends of the continuous tubular liner are roller expanded into a compression fit with the parent tube. The opposed ends of the continuous tubular liner may be flared into contact with flared ends of the parent tube. An apparatus for expanding a continuous tubular liner into a compression fit with a parent tube of a heat exchanger has a first tube sealing chuck attachable to one end of the continuous tubular liner; a second tube sealing chuck attachable to the other end of the continuous tubular liner; and a pump for supplying fluid to the interior of the continuous tubular liner through one of the tube sealing chucks. The pump has a liquid inlet and a gas inlet and a switching valve to select one or both of the inlets.
