Abstract: Disclosed are a laser transmission circuit, a laser transmission component and an electronic measuring instrument. The laser transmission circuit includes: an analog receiving unit, and a digital feedback path. The analog emission unit is configured to convert the accessed input analog signal into an analog laser signal, and emit the analog laser signal. The analog receiving unit is configured to convert the analog laser signal into an analog electrical signal as an output signal of the laser transmission circuit. An input end of the digital feedback path is connected to an output end of the analog receiving unit. An output end of the digital feedback path is connected to a feedback input end of the analog emission unit. The digital feedback path is configured to access the analog electrical signal output by the analog receiving unit, convert the analog electrical signal into a digital signal, and transmit the digital signal.

Abstract: A touch-sensing display module is provided, including a display unit and a film sensing structure. The display unit has a front surface, a rear surface opposite the front surface, and a side connecting the front surface and the rear surface. The film sensing structure is attached to the display unit and includes a main body and a bending portion connected to the main body, wherein the bending portion includes a slot. The bending portion extends from the front surface of the display unit to the rear surface along the side. The bending portion covers a portion of the side and a portion of the rear surface. A portion of the display unit is exposed by the slot.

Abstract: A die casting machine melt leakage detecting device includes a pulling wire, multiple wire winding columns, a wire fixing member, an elastic wire connecting member and a trigger switch. The pulling wire is capable of withstanding temperature outside a mold during normal die casting and is melted and broken after making contact with molten metal. The multiple wire winding columns are arranged around the mold, an end of the pulling wire is connected with the wire fixing member, and another end of the pulling wire is sequentially wound around the wire winding columns and is connected with the elastic wire connecting member. The elastic wire connecting member is opposite to the trigger switch, the elastic wire connecting member is in a compressed or stretched state when the pulling wire is kept tensioned in the operating state.
