Title: Method for feedback controlling the air and fuel ratio of the mixture supplied to an internal combustion engine
Inventor: ISHII JUNICHI
IPC: F02D41/14
Filed: 1989-03-22
Granted: 1991-12-24
Abstract: Abstract:   The present invention relates to a method for feedback controlling air-fuel ratio of the mixture supplied to an internal combustion engine having a pluraltiy of cylinders.  The method comprises the steps of, detecting respective air-fuel ratios of the exhaust gas from the respective cylinders with an air-fuel ratio sensor having a substantially linear output characteristic, calculating an average air-fuel ratio by using the latest detected air-fuel ratios of the respective cylinders and determining a fundamental feedback correction coefficient .beta.0 for a cylinder of which air fuel ratio is feedback controlled next.  The method further includes the steps of retrieving a learning correction coefficient .beta.1 for the cylinder of which air-fuel ratio is feedback controlled next from a learning map prepared by learning for the corresponding cylinder; and determining new learning correction coefficients .beta.1 for the respective cylinders using respective deviations of the respective detected current air-fuel ratios from the latest average air-fuel ratio calculated in the previous step.  As a result, air-fuel ratio control at any desired air-fuel ratio is carried out with a high accuracy and with a uniform air-fuel ratio throughout the whole cylinders.

Title: Method for applying flux to a substrate
Inventor: FISHER JOHN R
IPC: B23K3/00
Filed: 1989-03-01
Granted: 1991-12-31
Abstract: Abstract:          A controlled amount of flux is applied to a circuit board by first directing liquid flux through a nozzle containing means for disintegrating the flux into a very fine fog of tiny flux droplets.  The fog of flux droplets is injected into a laminar gas stream, thereby creating a laminar flux stream which is directed at the circuit board to coat the board with flux.  As the flux spray is being directed at the circuit board, the concentration of flux solids on the board is being regulated, typically by controlling the rate of flux pumped into the nozzle.

Title: Tank construction and method of manufacture
Inventor: LINDAHL JOHN R
IPC: B65D90/04
Filed: 1989-04-10
Granted: 1993-11-16
Abstract: Abstract of the Disclosure A tank construction including an outer shell of steel material comprised of two half members welded together.   The half members are formed by a deep drawing process.  An inner shell of non-corrosive material is cast inside the outer shell by a rotation-al casting procedure with the external surface of the inner shell located adjacent the internal surface of the outer shell.   The inner shell of non-corrosive material provides a substantially leak-tight liner for the outer shell to thus prevent contact between the contents of the tank and the outer shell.  The rota-tional casting of the inner shell inside the outer shell is accomplished by charging the outer shell with a non-corrosive material and then subjecting the outer shell to a rotational casting movement while heat is applied to the outer shell.  The outer shell serves as a mold for the inner shell wherein the mold (outer shell) becomes a permanent part of the completed tank.

Granted: 1992-11-24
Abstract: EXCHANGE SYSTEM HAVING ORIGINATING CALL          RESTRICTION FUNCTION           ABSTRACT OF THE DISCLOSURE    Disclosed is an exchange system having an originating call restriction function comprising a unit for counting originating calls, a unit for counting incoming calls, a storage unit for storing a number (No) of originating calls that can be accepted from accommodated subscribers (111) within a predetermined period, storage unit for storing a number (Ni) of incoming calls that can be accepted within a predetermined period, and a unit for correcting the number of calls that can be accepted.  The correction of the number of calls that can be accepted is effected by comparing the number (Ni) of incoming calls that can be accepted and a number (Nai) of accepted incoming calls. When the difference between the number (Ni) of incoming calls that can be accepted and the number (Nai) of accepted incoming calls is decreased below a predetermined value, the number (No) of originating calls that can be accepted is decreased by a predetermined correcting value (.alpha.), and the number (Ni) of incoming calls that can be accepted is increased by the correcting value (.alpha.),  Whereby, when there is processing congestion, the incoming call restriction level is relaxed and the originating call restriction level is increased.

Inventor: RUCKDESCHEL FRANZ
IPC: E04C5/08
Filed: 1989-07-18
Granted: 1993-01-19
Abstract: ABSTRACT OF THE DISCLOSURE           To  facilitate  the  construction  of  a  very  high structural member for use in a body of water such as at an off-shore location with the structural member extending from the floor of the body of water to above its surface, tensioning members are inserted into relatively narrow tensioning ducts accessible only from the top of the structural member.   The tensioning members, such as steel rods, steel wires, or steel wire strands, are provided with members for effecting a positive locking engagement in a hardenable material forming an anchored length of the tension member at the lower end of the tensioning ducts.   Initially, the tension members are lowered into the lower ends of the ducts and then are grouted in the ducts by a hardenable material.  After the hardenable material has set over an anchored length, the tension members are tensioned within the ducts.  Next, the tensioned length of the tension members in the ducts  is grouted with a hardenable material  to provide a composite action with the structural member. Accordingly, the tension members are securely positioned within the tensioning ducts and are effectively anchored.

A method of making a point contact semiconductor device, e.g. the diode shown, comprising a semi-conductor crystal 10, in which a part of the crystal is cleaned by removal of a surface layer as by grinding and/or etching and subsequently assembled in an envelope 17, is characterized in that the surface is covered immediately after cleaning with an insulating layer 16 and a point contact electrode 18 pushed through the layer to puncture it and in that the region around the puncture is subsequently occupied by a viscous insulating layer 21. In - the example shown, the crystal, originally in the form of a monocrystal Ge or Si sphere 10, is copper plated, soldered to connecting pin 12, ground to a flat surface, etched and immediately afterwards dipped in or sprayed with insulation 16, e.g. polystyrene in benzene. A layer 21 of viscous material, e.g. polymethyl siloxanes, is then applied to layer 16 and pin 12 and pin 19 bearing cat's-whisker 18 are inserted in metal sleeves 20 sealed in envelope 17 until the whisker punctures layer 16. The viscous layer is then consolidated by spinning the tube about axis Y. Instead of polystyrene or cellulose ester, alkyd resin or polyisobutylene may be used for the insulating layer.
