    • A pipe hanger hooks or unhooks lower ends of semicircular bands divided left and right by means of a hooking means, mounts mounting plates integrally formed at the lower end of a supporting bracket to mounting plates integrally formed at upper ends of the semicircular bands, provides a resiliently biasing means in the supporting bracket to resiliently bias a nut block in an upward direction, couples a locking plate or rod into the mounting plates of the other-side semicircular band and the supporting bracket, mounts a locking cap and a locking guide to the mounting plate of the one-side semicircular band, and forms a hock of the lower end of the other-side semicircular band so as to extend beyond the vertical center line of an inner space defined by the semicircular bands. Thereby, the resiliently biasing means is provided in the supporting bracket to thus retain toe nut block, so that it is possible to prevent the supporting rod fixed to the ceiling of a building from being unfastened while the supporting rod is prevented from swaying by external impacts. The locking plate or rod coupled into the mounting plates of Lie other-side semicircular band and the supporting bracket is easily locked to or unlocked from the locking guide mounted to the mounting plate of the one-side semicircular band, so that the pipe is readily installed. The pipe, which is seated by the hook of the other-side semicircular band which extends beyond the vertical center line of the inner space defined by the semicircular bands, is supported, so that the one-side semicircular band can be readily mounted while preventing the seated pipe from falling down.

    • The present invention discloses an infrared bolometer including a signal bridge used for reading a resistance value varied by infrared heat and removing residual heat of a heat absorbing layer. The infrared bolometer includes a lower substrate having an integrated circuit coated with a protection layer, an upper substrate having an absorbing layer for absorbing infrared rays and a resistor whose resistance value is varied by the infrared heat absorbed by the absorbing layer and spaced apart from the lower substrate by a predetermined distance,a post for mechanically supporting the upper substrate and connecting the upper and lower substrate to each other, and a signal bridge arranged between the lower and upper substrates for transmitting a signal from the resistor of the upper substrate to the lower substrate. The infrared bolometer further includes a lower electrode formed on the top surface of the lower substrate for driving the signal bridge to be electrically connected/disconnected to/from the upper substrate, and a reflecting layer formed on the top surface of the lower substrate for increasing absorptivity of infrared heat.
