Abstract: An infant drinking cup is described. The infant drinking cup is a first color when at room temperature. When the cup is filled with a cold beverage, the portion of the cup below the fill line changes to a second color. When handled by an infant, those areas below the fill line in contact with the infant's warm hands change color back to the first color. The process is fully reversible, such that the infant drinking cup can change from the cold color to the warm color, and vice versa, repeatedly.

Abstract: An ink jet print head by which ink droplet ejected from all orifices are adapted to have uniform size has the following structure. Each of a plurality of ink chambers divided by partitions is communicated with a common pressure chamber with a first filter interposed. Common pressure chamber is communicated with a common ink feed path with a second filter interposed. Common pressure chamber and each of the ink chambers are covered by a pressure chamber ceiling. On pressure chamber ceiling, a piezo vibrator is provided at a position corresponding to common pressure chamber. A movable wall which is bent and deformed to the side increasing the volume is provided corresponding to each partition. By driving a piezo vibrator, a pressure wave is generated in common pressure chamber, which wave is transmitted to each ink chamber through the first filter. When movable wall is bent and deformed, the pressure wave is absorbed, so that an ink droplet is not ejected.

Abstract: Semi-spherical supports are used in the piercing of small, consistently sized holes in a soft metal. In particular, a flow control device, such as an orifice plate, can be fabricated with small, consistently sized flow apertures to regulate flow in a gas flow regulating device. By using semi-spherical supports, the need for hand-punching and real-time flow calibration can be avoided and automated machinery with a tapered piercing tool can be used to fabricate the flow control device.

Abstract: A pressure transmitter with a transmitter housing having an outer wall providing thermal resistance. The outer wall extends from an isothermal island at a first end to a heat sink island at a second end. The isothermal island includes a fluid inlet, and pressure and temperature sensors. The heat sink island includes a primary heat load device that is heat sunk to an outer shell of an electrical connector. The connector contacts carry a current controlled by the transmitter, and a portion of the current is conducted by a primary heat load device. A circuit board controls the current to represent the pressure. A high accuracy, temperature compensated current output represents pressure.

Abstract: In a normal record mode, a non-heat mode such that a non-ejecting pulse for heating is not supplied when the image recording is not executed is set. In a continuous magnify-record mode, a heat mode such that the non-ejecting pulse for heating is supplied when the image recording is not executed is set. Thus, a non-uniformity of an image density at the start and end of the recording can be suppressed and a reduction of the life of the head can be minimized.

Abstract: A process for activating an oscillator serving to oscillate a Coriolis line of a Coriolis mass flowmeter for moving fluids, and of a power supply circuit system for an oscillator of a mass flowmeter for moving fluids operating by the Coriolis principle. The oscillator is supplied a pulse-width-modulated pulsed sinusoidal signal. The resulting heat-loss reduction in an amplifier circuit leads to a better utilization of the energy available for supplying the oscillator.

Abstract: The apparatus employs a steel ball which is mounted in upstanding manner on a pin and a frame on which a golf club is pivotally mounted to freely pivot. The golf club is pivoted from a fixed position to impact the head of a golf club against the steel ball and an oscilloscope is used to record the acceleration and movement of the steel ball from its fixed point in response to the impact of the head and also calculates a velocity history of the steel ball. The time at which the calculated velocity is at a maximum is determined. Several impacts are made to obtain an average characteristics time (tz) and the representative spring constant (Kc) of the clubhead is calculated using the equation: Kc=0.2971×tz−2.15570.

Abstract: An improved method and system for measuring a multi-phase flow in a pressure flow meter. An extended throat venturi is used and pressure of the multi-phase flow is measured at three or more positions in the venturi, which define two or more pressure differentials in the flow conduit.

The system for determining the mass flow of the high void fraction fluid flow and the gas flow includes taking into account a pressure drop experienced by the gas phase due to work performed by the gas phase in accelerating the liquid phase.

Abstract: A torque apparatus for the installation and removal of threaded connecting device that employs a plurality of leaf spring elements engaging a plurality of asymmetrical drive teeth sides to establish preset torque values in a hermetically sealed configuration or a variable range of preset torque values in a second configuration. The preset torque values can be readily changed in the second configuration by employing different quantities of leaf springs, differing leaf spring designs, or varying the geometry of the rotor drive teeth. The leaf spring to rotor drive teeth interface provides a slip mechanism to prevent over-torquing when torque values for the installation of a threaded connecting type device is exceeded. While both torque wrench configurations are sterilizable, the torque wrench that is capable of full disassembly for sterilization and use thereafter in a sterilized environment, is reconfigurable for different torque applications without calibration.

Abstract: A system for determining engine phase in a motorcycle engine includes a crank gear sensor mounted near the crank gear of the engine, a pressure sensor mounted on the air intake manifold of the engine, and a processor communicating with the crank gear sensor and the pressure sensor. First and second groups of crank gear teeth pass by the crank gear sensor before either of the first and second pistons of the engine reaches TDC. A third group of crank gear teeth passes by the crank gear sensor before the first piston reaches TDC, but after the second piston reaches TDC. At low rpm, such as at start up, the processor determines the phase of the engine during a single rotation of the crankshaft by measuring and comparing the time periods taken by the group of teeth to pass by the crank gear sensor. At high rpm, the processor determines the phase of the engine using the pressure sensor.
