  • Publication number: 20240377726
    Abstract: The present disclosure provides a pellicle that includes: a pellicle frame; a pellicle film supported at one end surface of the pellicle frame; and an adhesive layer provided at another end surface of the pellicle frame, and satisfies the following Equation (1): [A60° C.]?4.0 gf/mm2 (1). In Equation (1), [A60° C.] represents a first peel strength when the pellicle is used in a test laminated body. The test laminated body is obtained by placing the pellicle on a quartz glass substrate such that the adhesive layer is in contact with a surface of the quartz glass substrate, and maintaining a load on the pellicle under prescribed conditions. The first peel strength represents a load per unit adhesion area, which load is required for peeling the pellicle included in the test laminated body from the quartz glass substrate using a standard universal tester under prescribed conditions.

  • Patent number: 11802846
    Abstract: An oxygen concentration meter includes a zirconia sensor, a resistor, a constant-current circuit, a resistance detection section, and an oxygen concentration detection section. The resistor is connected in parallel to the zirconia sensor. The constant-current circuit is connected in parallel to the zirconia sensor and the resistor, and supplies an electric current. The resistance detection section detects the resistance of the zirconia sensor on the basis of the voltage of the zirconia sensor in accordance with the supplied electric current. The oxygen concentration detection section detects the oxygen concentration of gas to be measured that is supplied to the zirconia sensor, on the basis of the voltage of the zirconia sensor resulting from an oxygen concentration difference between the gas to be measured and reference gas.

  • Patent number: 11621779
    Abstract: An optical transmission system (10) includes a plurality of transmission devices such as transponders (TPs) and optical cross-connects (OXCs) installed in each of stations (11-15) connected via a communication network, a control device (20), and a substitute OXC (502) serving as a substitute transmission device. The control device 20 is installed in a control station (14) of the stations. The control device (20) controls the transmission devices of the stations (11-15) in a centralized manner in accordance with physical network (NW) configuration information (20D) stored in a DB (21) and including config information. When a transmission device is replaced with a new OXC (5o3) serving as a new transmission device, the substitute OXC (5o2) operates as a substitute for the new OXC (5o3) to communicate with the control device (20) until config setting necessary for the new OXC (5o3) is completed.
