IPC: F25B41/00
Filed: 1997-03-21
Abstract: PROBLEM TO BE SOLVED: To prevent a pipe from being deformed in the coiling direction even when the thermal expansion of a cylinder is different from that of the pipe by fixing adjacent parts of the pipe to be coiled around the outer circumference of the pipe in which the combustion gas is passed to each other. SOLUTION: A fin 6 is integratedly formed inside a cylinder 1, and a pipe 2 is coiled around the outer circumference of the cylinder 1. Adjacent parts of the coiled pipe 2 are fixed to each other by the spot welding. When adjacent part of the pipe 2 are spot-welded to each other, the pipe 2 coiled around the cylinder 1 is of integrated structure, and each part is nor expanded nor contracted in the coiling direction even when each part is expanded/contracted in the radial direction together with the cylinder 1. That means, even when the operation of a combustion part is stopped, no expansion/contraction by the heat in the coiling direction of the pipe 2 is generated, and no rubbing with the cylinder 1 is generated. Welding can be easily performed by spot welding.

Title: Reflection type liquid crystal electro-optic device
Inventor: SONEHARA TOMIO
IPC: G02F1/1365
Filed: 1999-03-15
Abstract: PROBLEM TO BE SOLVED: To obtain a reflection type electro-optic device which allows the use of the conventional switching element array as it is and does not require the alignment with a light shielding mask by providing the other substrate of a pair of substrates with a reflector. SOLUTION: This device is constituted by holding a liquid crystal layer 104 between a pair of the substrates 102, 103. The one substrate 103 of a pair of the substrates 102, 103 is provided with pixel electrodes 105 arranged to a matrix form and the switching elements 107 connected the pixel electrodes 105. The other substrate 102 is provided with the reflector 101. When linearly polarized light is made incident while voltage is zero, the locus of elliptically polarized light rotates and turns to nearly circularly polarized light on the surface of the reflector 101 and the phase is rotated 180 deg.C. The light transmits the liquid crystal layer 104 again and is emitted as the linearly polarized light rotated in the plane of nearly 90 deg. polarization at the exit surface.  When the voltage is impressed, liquid crystal molecules are realigned to an electric field direction on account of the anisotropy of the dielectric constant. As a result, the anisotropy of the double refraction to the incident light disappears and the incident linearly polarized light is emitted while the polarized light is maintained as it is.
