Patent JP-3081375-B2 (JP)
IPC: C08F4/78
Filed: 1992-07-16
Granted: 2000-08-28
Abstract: The present invention concerns a method for preparing heterogeneous catalysts. According to the method, preparation is carried out under such process conditions in which the bonding of compounds from the gas phase onto the surface of a support material is primarily determined by the properties of the support surface. The constituents contained in the reagent are then selectively bonded to the bonding sites of the support material surface, thus forming stable surface bonds. According to the invention, the number of surface-bond sites available for preparing a stable product with surface bonds is controlled by varying the reaction temperature and/or selecting a suitable reagent. The invention makes it possible to control the metal content of the end product at a predetermined level. <IMAGE>

Abstract: PROBLEM TO BE SOLVED: To protect a substrate against crackings or chippings and to prevent aggregations/projections due to solder climbing onto the upper surface of a semiconductor substrate by forming a step at the fringe of the substrate and jointing the substrate and a package through soldering. SOLUTION: A semiconductor substrate 1, having a circuit formed on the upper surface, is sliced into a thin film and an L-shaped step 5 is formed in the vertical cross-section of the substrate 1 in the outer circumferential region thereof, while a metal film 2 is formed on all surfaces other than the upper surface. The substrate 1 is jointed to the recess 9b of a package 9 via the metal film 2 by means of a solder 3. When the substrate 1 is mounted on the package 9, the solder 3 climbing from the side face part of the substrate 1 aggregates at the L-shaped step 5 to form a protrusion 6. Since the protrusion 6 of the solder 2 is wetted at the L-shaped step 5, it will not protrude, and the height thereof can be suppressed substantially equally to those of the substrate 1 and the package 9. Furthermore, outer circumferential part of the substrate can be prevented from being chipped and the like by the solder 3 aggregating at the step 5.

Abstract: An absorbent article with an absorbent body enclosed between inner and outer casing sheets and a stiffening element extending from the rear, through the intermediate, and into the front part of the article. The stiffening element's front and rear parts are broader than its intermediate part and the stiffening element is not wider than 4 cm at its front to intermediate transition region. Side flaps are formed by at least some parts of the remainder of the article which extend laterally beyond the stiffening element, so that the distance between side-edges of the stiffening element and an edge of the side flap varies within the region. The stretch resistance of the side flaps is greater than the stiffening element's longitudinal bending resistance, so inward pressing of the side flaps causes the stiffening element to curve longitudinally, to obtain an upwardly concave shape adapted to the shape of a wearer's body.

Abstract: An arc diverter detects an arc between the cathode and the anode of a glow discharge apparatus and in response to arc detection, actuates a switching network that triggers a pair of switches to allow a capacitor to discharge toward the cathode along a resonant diverting path and recharge the capacitor for subsequent discharge in an opposite direction. This discharge current effectively short circuits the power supply and extinguishes the arc. The resonant diverting circuit includes two resonant diverting paths and four switches configured in an "H" to hold the capacitor in a charged condition. Alternate triggering of the diagonally situated pairs of switches enables the charged capacitor to discharge in one direction along one of the resonant diverting paths and recharge for subsequent discharge in the opposite direction, along the other of the resonant paths. Both resonant diverting paths provide discharge toward the cathode.

Abstract: The invention provides a method and apparatus for switching between execution of a plurality of object code types having different conventions for invoking program procedures and performing stack manipulations. The invention may also be used to switch between different calling conventions within a single object code type. Briefly according to the invention, a computer system comprises a routine descriptor, a stack switch frame, a mode switching mechanism for switching from a first processor, code or calling convention type to a second processor, code or calling convention type and means for executing instructions in various code types.A routine descriptor describes a program or code segment and its code type and calling conventions. A routine descriptor contains, among other information, a "mixed mode" field which is set to a specific, predetermined value such as a value indicating an instruction which is not legal in the runtime environment of a first processor, code or calling convention type. When that instruction is encountered, control is transferred to the mode switching mechanism. A routine descriptor also contains a "procedure information" field which is set to a value indicating the convention for invoking a program segment and performing appropriate stack manipulations.When a routine calls a routine having a different stack model, the mode switching mechanism uses a stack switch frame to provide a transition between the two different stack types.

Each pellet contains a core containing the therapeutic drug and a water soluble osmotic agent. A water-permeable, water-insoluble polymer film encloses each core. Incorporated into the polymer film is a hydrophobic, water insoluble agent which alters the permeability of the polymer film. The film coating of each population of pellets differs from the coating of every other population of pellets in the dosage form in the rate at which water passes through to the core and the rate at which drug diffuses out of the core. The osmotic agent dissolves in the water, causing the pellet to swell and regulating the rate of diffusion of drug into the environment of use. As each population of pellets releases its drug into the environment sequentially, the effect is to provide a series of pulsatile administrations of the drug from a single dosage form.
