Abstract:
A weight member for a golf club head is made of a WFeNi alloy by a precision casting process. The WFeNi alloy includes nickel 30-60 wt %, tungsten 15-30 wt %, chromium 1.5-10.0 wt %, and iron that is the remaining portion. Chromium improves the rust resisting property of the weight member and lengthens the life of the weight member. Uniformity of shining finishing of the weight member can be improved by controlling a mixture ratio of nickel to tungsten. Silicon may be added to improve the flowability of the molten metal. Manganese, copper, vanadium, and niobium may be added to improve the mechanical properties of the weight member.

The metal core electrode and the electrode of external conductive layer are charged with a voltage of AC50-400V and a frequency of 0.05 KHz to 20 KHz to produce a colored highly bright light.
Abstract:
Various embodiments of a low-power-consumption analog-to-digital converter (“ADC”) for a touchscreen or touch panel in a capacitive sensing system are disclosed. The ADC is configured to operate in a first mode or a second mode. The first mode is characterized by a first resolution having a first number of ADC bits and a first level of power consumption associated therewith. The second mode is characterized by a second resolution having a second number of bits and a second level of power consumption associated therewith. The ADC operates under control of the controller and is configured such that the first number of bits is greater than the second number of bits and the first power level is greater than the second power level. The controller causes the ADC to switch from operating in the first mode to operating in the second mode when low radio frequency (RF) noise conditions are detected by sense circuitry, the ADC and/or the controller.
Abstract:
The present invention discloses a sample feeding device for an ion mobility spectrometer, which is adapted to guide a sample to be detected into an inlet of a drift tube of the ion mobility spectrometer. The sample feeding device comprises a solid sample feeding component; a sample inlet component; a attachment component, wherein the solid sample feeding component has an internal cavity defined therein, one end of the solid sample feeding component is communicated with the sample inlet component through the internal cavity, while the other end is communicated with the inlet of the ion drift tube through the attachment component; and a gaseous sample feeding component, comprising a body and an external attachment component, the body has a gas channel therein, and the external attachment component includes an inlet hole which is communicated with the gas channel, wherein when the external attachment component is fitted with the sample inlet component, the body is inserted into the internal cavity, so that a channel of the solid sample feeding component is closed, and only the gas channel of the gaseous sample feeding component is communicated with the inlet of the drift tube of the ion mobility spectrometer.
Abstract:
The present application relates to methods for sending an email and distributing an email, and an email server. According to the application, a summary is generated for an email to be sent, with the email stored in a sender side server; the summary of the email is sent to a receiver side server; and the email is sent to the receiver side server in response to receiving, by the sender side server, a request for sending the email, the request being sent by a recipient based on the summary. Thus, the network bandwidth, the storage space of the email server and user terminals may be saved.
