Title: Optical deflector
Inventor: MIKAMI KAZUO
IPC: G02F1/29
Filed: 1983-05-28
Abstract: PURPOSE:To realize two-dimensional optical scanning which is high in speed and resolving power, by arranging two platy optical crystals, which are equipped with electrodes having prescribed shapes and different in the direction of crystal axes by 90 deg., to the front and back of an optical path and making a linear polarized light which is polarized by 45 deg. to the crystal axes incident. CONSTITUTION:Four groups of four electrodes 15-18, 19-22, 26-29, and 30-33 having a circular arc end margin are respectively installed to the surface and back of two electrooptic crystals 14 and 25, whose optical axes cross at right angles, and connected with each other through power sources 23 and 24 and switches 24 and 35. When a circular optical beam F having a plane of polarization E in the Zaxes direction is projected to the end face 14a of the crystal 14, the optical beam is deflected in the right-left direction by an electric field produced by a voltage V1 from the power source 23. Moreover, when the optical beam is made incident to the end face 28a of the crytal 25, the beam is deflected in the vertical direction by another electric field produced by the voltage V2 of the power source 34, and thus, two-dimensional scanning is performed through a condenser lens 13. Since electrooptic crystals are used for deflectors 11 and 12, high-speed optical scanning is realized.

IPC: F24F13/30
Filed: 1990-04-13
Abstract: PURPOSE:To prevent deformation of a casing and occurrence of creak sound caused by a thermal expansion difference between a heat exchanger and the casing by a method wherein either one end of the heat exchanger is fixed to the casing and the other end is movable only in the rightward or leftward direction of an indoor device and restricted in the other direction. CONSTITUTION:A holder 1 is fixed by a screw 10 in such a way as its upper surface 4 shows the same height as that of an upper and surface 21 of a partition wall 12. The lateral width L1 of a clearance 3 is equal to the lateral width of a tongue 7. The height (t) of the clearance 3 is equal to the plate thickness of the tongue 7. The tongue 7 is assembled in such a way as there is no looseness in the clearance 3 and it may be smoothly slid. Thus, the tongue 7 can be moved in the rightward or leftward direction of an indoor device, but restricted in other direction, so that a heat exchanger 18 and a casing 14 are not separated, but held. When the casing 14 is extended in a direction A due to its thermal expansion, a U-shaped part 2 is smoothly slid in the direction A against the tongue 7. The length L3 of the U-shaped part is longer than the thermal expansion difference at the highest temperature actually applied and then the tongue 7 is not removed from the U-shaped part 2.
