Title: Low-expansion metal foil and laminated board for printed circuit
Inventor: UEKI MASAAKI
IPC: H05K3/00
Filed: 1992-12-17
Abstract: PURPOSE:To obtain a laminated board, for a printed circuit, wherein its coefficient of thermal expansion is small, it does not cause any solder crack, its reliability of a through hole is excellent and it is optimum for mounting a CLCC or the like. CONSTITUTION:In a laminated board for a printed circuit, a baron nitride-based low-expansion metal foil is used on the surface of the laminated board. Thereby, a layer whose coefficient of thermal expansion is low restrains the part of the laminated board form being expanded, and the coefficient of thermal expansion in a face direction of a circuit board as a whole can be reduced. When a low-expansion part is added also in a thickness direction, the coefficient of thermal expansion as a whole including the thickness direction can be reduced. A low expansion by a low-expansion metal foil can display a larger effect when a multilayer board is manufactured. As a result, the coefficient of thermal expansion in the face direction is matched to a semiconductor device such as a CLCC, a TSOP or the like, and the reliability of a through hole can be enhanced.

Title: Electronic gas metering device and electronic gas meter
Inventor: TANAKA SHINICHI
IPC: G01F1/00
Filed: 1998-12-14
Abstract: PROBLEM TO BE SOLVED: To suppress a wrong integration of an actually unconsumed gas flow mistaken for a consumed gas flow by upstream pressure fluctuation. SOLUTION: A flow metering means 100 measures intermittently a physical quantity varying according to a gas flow velocity in a gas duct 10, and meters a flow therethrough, by multiplying the physical quantity by a cross section of the gas duct 10 and by the intermittent time interval. A flow integrating means 200 computes an integrated flow on the basis of the metered flow through the gas duct 10. The gas flow through the gas duct 10, metered by the flow metering means 100, is integrated when the gas flows in the downstream direction of the gas duct 10, and is subtracted when the gas flows in the upstream direction of the gas duct 10, while a predetermined value is subtracted from the integrated value each time the integrated value exceeds the predetermined value.  A second integrating means 14a-2 computes the integrated flow by adding the predetermined value each time the integrated value reaches the predetermined value.

Title: Fluoride flux for brazing aluminum
Inventor: TAKAHASHI SUSUMU
IPC: B23K35/363
Filed: 1991-12-04
Abstract: PURPOSE:To obtain the flux for brazing an aluminum alloy excellent in corrosion resistance capable of brazing the aluminum alloy containing magnesium by constituting the flux of only a fluoride not containing a chloride and composing the flux of specified components containing lithium fluoride. CONSTITUTION:The composition of the flux is mixture of eutectic salt or powder thereof composed of 39-49.5mol% KF, 44.5-49.5% AlF3 and 0.75-16.5% LiF. Since the flux contains the lithium fluoride, even if it is used for brazing the aluminum alloy containing magnesium, high melting point magnesium fluoride is not generated and hence brazing is made possible at the normal brazing temperature. In addition, since the flux does not contain the chloride and uses only the fluoride, it is also excellent in corrosion resistance after brazing.

Title: Method and apparatus for controlling injection molding machine
Inventor: YAMAZAKI TAKATOSHI
IPC: B29C45/77
Filed: 1991-12-27
Abstract: PURPOSE:To realize the accurate changeover control at the time of the changeover of a filling process to a dwell process, in controlling the driving of the actuator to be controlled of an injection molding machine by a proportional electromagnetic type pressure flow rate control variable pump, by controlling the operation of the actuator to be controlled on the basis of the swash plate angle of a proportional pump. CONSTITUTION:Since a speed is controlled in a filling process, the emitting amount from a proportional pump 2 becomes much and a swash plate angle Q also becomes large. As a result, a piston part 16 moves to the left and a screw 3 advances and the feedback control to a screw speed is performed. The optimum set angle Qs to the swash plate angle for changing over the filling process to a dwell process is preset to a control part 6. Therefore, the control part 6 monitors the magnitude of the swash plate angle Q detected from a potentiometer 31 and controls the changeover of the filling process to the dwell process when the magnitude of the swash plate angle Q becomes small to become the set angle Qs or less.

Title: Atm switch queuing system
Inventor: WILLS JEFFREY MERLIN
IPC: H04L12/56
Filed: 1997-12-26
Abstract: PROBLEM TO BE SOLVED: To provide an ATM switch which quickly distributes buffering action, maximizes fast transmission of time critical data and minimizes transmission loss in a back pressure system. SOLUTION: An input port 23 transmits a cell from an input buffer in response to plural priority levels. Each output port 23 has an output buffer that retains a cell when the cell arrives from the input port faster than that the output port transmits it. The output port also transmits a cell from the output buffer in response to plural priority levels. A back pressure signal circuit sends a signal from the congested output buffer to the input buffer that just transmits a cell to the output buffer through a switch structure 10, and stops the transmission of the input port buffer. An ATM switch drops a cell based on previously connected reference more than a cell priority level. A penalty is imposed on a sender who makes congestion cause data more, than other users of the ATM switch.
