Title: Linear motor
Inventor: HASEGAWA TARO
IPC: H02K41/02
Filed: 2000-07-21
Abstract: PROBLEM TO BE SOLVED: To provide a core-fitted linear motor, which linearly and movably holds the moving element of an armature, that is formed by disposing poles of an electrical steel sheet, wound with a coil in the moving direction between two field-forming stators opposing in parallel with each other, where permanent magnets are disposed and fixed, such that each different pole is alternately oriented in the longitudinal direction, with a coil-cooling means suitable for a high-load operation under severe conditions;  adding to the previously advantages hitherto carried with the motor such that high accuracy is obtainable by the offset of the forces of magnetic attraction of two air gaps, such that cogging and thrust ripple are easily reduced due to various kinds of structures, and such that heat generation of the coil can be reduced by directly winding the coil to a core in proper alignment. SOLUTION: In the motor comprising the moving element of an armature, having a prescribed gap between the poles to which adjoining coils are wound, a cooling means for the coil and poles of the moving element is formed from a strip and flat cooling tube that is arranged so as to fold back vertically creeping from one end to another end of the longitudinal direction of the moving element and to fill the gap of the adjoining poles. Then, both ends of the cooling tube are connected to the opening for a feed-and-emission of a coolant, through a manifold mounted at the end of the moving element.

Title: Liquid crystal projector
Inventor: NAKAYAMA MITSUO
IPC: G02F1/1335
Filed: 2000-08-03
Abstract: PROBLEM TO BE SOLVED: To prevent deterioration in the performance due to heat and to transmit enough quantity of light even in a half area in a liquid crystal projector equipped with a light source, color separation and synthesis means and projecting lens, by adding a heat radiating function to a polarizer disposed in the light-exiting side of a liquid crystal panel. SOLUTION: The heat flux emitting from a lamp in a reflector 4 generates natural light which is then changed by a fly eye lens 3 and a P/S synthesis prism 8 into linearly polarized light in the transmission direction which transmits the incident side polarizing plate 7 of a liquid crystal. When the beam of the linearly polarized light exiting from the fly eye lens 3 and P/S synthesis prism 8 has 100 power, the transmittance for parallel light of the incident side polarizing plate 7 is almost 80% so that 20% of the light is absorbed by the incident side polarizing plate 7 to generate heat. Then a heat radiating plate is attached to a heat transmitting transparent substrate 1 to which a polarizing sheet is adhered as an exit side polarizing plate.  Thus, by using the transparent substrate having no influences on the light emitting from the light source to reach the screen so as to improve the heat conduction, deterioration of the polarizing plate due to heat is prevented.
