Abstract:
There is provided a liquid-tight slide fastener capable of sufficiently ensuring waterproof property regardless of where fastener elements are formed and capable of sufficiently ensuring attachment strength of the fastener elements to fastener tapes provided with liquid-tight layers. There is also provided a manufacturing method for the liquid-tight slide fastener. The liquid-tight slide fastener includes a pair of fastener tapes that include a pair of tape members, core sections respectively provided on opposing tape edges of the pair of tape members, and liquid-tight layers formed on one side of the pair of tape members; a pair of fastener element rows; and a slider. The liquid-tight layers are formed with gaps to the core sections in a width direction of the fastener tapes. The fastener elements are attached to the core sections.
Abstract:
An improved structure of a photo sensor is disclosed. Its structural feature is that a PIN photo diode is allocated in a MOSFET, by means of enlarging the detected small photo current from PIN photo diode by the MOSFET; so as to avoid the shortcoming of conventional PIN photo diode, and enhance the sensitivity of photo sensing.
