The invention relates to an injection pen. The injection pen comprises a refill shell, a push rod, an internal-thread shaft sleeve, a triangular movable racket wheel, a spring and a limiting joint, wherein the push rod penetrates through the refill shell; the internal-thread shaft sleeve, the triangular movable racket wheel and the spring are arranged in the refill shell; the limiting joint is clamped at the lower end of the refill shell; the push rod is provided with screw threads of a certain length; a pawl is attached to the end of the screw threads; the internal-thread shaft sleeve is spirally fixed on the screw threads on the push rod; the triangular movable racket wheel is embedded into the push rod, and is meshed with the pawl on the push rod; the spring is embedded into the push rod; one end of the spring is pressed against the triangular movable racket wheel, and the other end of the spring is pressed against the limiting joint; the limiting joint is connected to the push rod in a sleeving way. The injection pen has the advantages of simple structure, convenience in use and operation, accuracy in injection, low production cost, compact structure and easiness in carrying.

The method comprises: setting a built-in selection menu in mobile phone; the selection menu is displayed on a display screen of the mobile phone; in the selection menu there are selectable function modes items for use in different groups; the function mode items comprises at least a elder function mode, a children function mode and a blind-man function mode. After a user (elder, child or blind-man) selects one function mode item, the mobile phone enters into the selected function mode, opens the group setting of the function mode and displays it through display screen.

The invention provides a method and a device for realizing remote regulation of currents of an inverter welding machine based on welding time. For the particularity of manual electric arc welding occasions, regulation of the currents of the welding machine is a time-consuming, troublesome and frustrating thing for an operator. According to the method and the device for realizing the remote regulation of the currents of the inverter welding machine based on the welding time, the detected welding time is adopted as remote control commands of encoding, a remote controller is not needed any more so that the remote control and adjustment of the currents can be realized without operating any accessories, and therefore the electric welding operator can apply a remote control system simply and efficiently; receiving modules for processing the remote control commands comprise a time detecting module, a time filtering module, an encoding and decoding module and a special driver driving a digital potentiometer or an electric potentiometer to operate so as to realize stepless regulation of the currents of the welding machine; and the regulation effect of the currents can be observed by the operator and can be subjectively determined in real time. The method and the device for realizing the remote regulation of the currents of the inverter welding machine based on the welding time are suitable for the inverter welding machine for overlapping the form of wireless remote control and regulation of the currents under the condition of reserving the function of manually regulating the currents and meanwhile are suitable for the newly-designed welding machine to be integrated on a PCB.

A call method of a terminal and a terminal using the call method, are provided to adjust voice quality of a call in real time. The method includes analyzing a spectral component of a voice signal during a call and selecting a corresponding frequency response channel according to an analysis result of the spectral component of the voice signal.
