Abstract: A vehicle-velocity calculating apparatus which is easy to mount on a vehicle and is free from the influence of the gravitational acceleration includes an input terminal end connectable to a cigarette lighter outlet provided in a vehicle. Connected to the input terminal end is the input terminal of a noise filter. A counter is coupled at its input terminal to the output terminal of the noise filter. Connected to the output terminal of the counter is the input terminal of a velocity calculating circuit. The velocity calculating circuit calculates, in accordance with an output signal from the counter, the operating velocity of a vehicle, which is proportional to the frequency of a pulsating component generated in the vehicle's generator. The output terminal of the velocity calculating circuit is connected to an output terminal end. The vehicle operating velocity is thus obtained from the output terminal end.

Abstract: The surge pressure ratio of a compressor is determined by transiently reducing the inlet flow to the compressor to increase the compressor pressure ratio sufficiently to produce the surge pressure ratio. The reduction in flow of fluid is maintained for a time period insufficient to exceed the exhaust gas temperature limit for the turbine. The area of the first-stage nozzle of the turbine is reduced and the inlet flow to the compressor is reduced to a steady state to achieve pressure ratios, in close proximity to the surge line. By transiently further reducing the inlet flow to the compressor and then increasing the inlet flow back to the steady-state condition, the surge pressure ratio can be obtained without exceeding machine operational limits.

Abstract: The present invention presents a method that effectively provides the near real-time advantage of annular pressure while drilling (APWD) measurements taken during pipe connections that require the mud circulation pumps to be turned off (a “pumps-off” condition). APWD data, such as pressure measurements, are obtained from instruments and related electronics within the bottom-hole assembly (BHA). APWD data can be measured, stored and even processed in the BHA during a pumps-off condition for subsequent processing or communication of a reduced amount of data to the driller at the surface.

Abstract: An air flow meter disposed in an intake pipe has a bypass member having a U-shaped bypass passage, into which part of air flowing through the intake pipe is introduced. An outflow port disposed at a downstream air side of the bypass passage is surrounded at its three sides by opposing surfaces of a pair of side walls and a wall surface of a partition wall disposed at “an upstream air side of the outflow port”. Further, the outflow port is opened in an air flow direction in the bypass passage and in an air flow direction in the air flow passage. Therefore, air flowing through the bypass passage is partially discharged into the air flow passage through the outflow port gradually before joining main air flow in the air flow passage, thereby restricting decrease in air flow velocity and occurrence of turbulence in the bypass passage.

Abstract: The present invention provides methods and systems for forming deposition films on semiconductor wafers. In particular, the present invention measures the amount of liquid remaining in a bubbler ampule of a semiconductor processing system used for chemical vapor deposition (CVD) on a semiconductor wafer. More particularly, measurements are made when gas has stopped flowing through the ampule, and the liquid is in a static condition. The system of the present invention comprises a container containing a liquid, a gas inlet for introduction of gas into the liquid, a gas outlet, and a pressure transducer fluidly connected to the gas inlet and the gas outlet. The device measures the amount of liquid in a bubbler ampule through measurements of gas pressure differential between gas exiting a nozzle near the bottom of the liquid and gas located above the level of the liquid. The depth of liquid remaining in the ampule may be extrapolated from the measured pressure differential.

Abstract: An air flow testing device for use with a clothes dryer to indicate an obstruction in the exhaust system. Three potential states of exhausted air are monitored by the testing device when the dryer's lint screen is removed from its opening. In the first state, when the exhaust system is unobstructed, an impeller of the device freely turns within a casing held against the lint screen opening as the dryer is operating. In the second state, when the exhaust system is blocked, the same impeller remains static and does not rotate. In the third state when the exhaust system is partially blocked, the impeller moves and may stop. If either a fully or partially blocked state is detected, a user can simply clear the system including the tubing and flapper to resolve this common dryer problem without calling in a repair person.

Abstract: A new method and apparatus is provided for obtaining a quantitative reading of the strength of the chip bonding connections and for testing the quality of the bonding that is established between a chip and the chip pad or tapes on which the chip is mounted. The invention makes use of the fact that the lead frame, that is the frame that contains the leads to which the chip is connected, uses a material for the metal interconnects that can be controlled by a magnetic field. A metal alloy is commonly used to fabricate the interconnect leads on the lead frame.

Ni—Fe is an alloy that is frequently used as the material for the metal interconnects on the lead frame.

The position of the cut is pre-set by register marks printed on the web. In this process, the cutting device is fully automatically synchronized with the register marks. This is accomplished via a computer-supported controller which, via sensors, first determines the spacing between two adjacent marks, then adjusts the cutting device to the determined length of the section, and finally continually monitors the phase position between the knife and the register mark and changes the phase position by slightly accelerating or slowing down the material web until the cut and the register mark coincide.

Abstract: The invention relates to an arrangement in connection with a fiber process, the arrangement being provided with a control and drawing device for guiding a fiber or the like along a desired course, and with a cutting device for cutting the fiber or the like at a moment dependent on the fiber process.
