Title: Photosensitive polarizing film, liquid crystal display element using that and production of those
Inventor: NISHIGUCHI KENJI
IPC: B29D11/00
Filed: 1996-03-26
Abstract: PROBLEM TO BE SOLVED: To form a specified pattern by using a film containing a dichroic dye or iodine, a specified polymer and a photosensitive agent and uniaxially orienting the film. SOLUTION: A raw web film (A) containing a dichroic dye and a polymer which can be decomposed with light is uniaxially stretched by stretching treatment to obtain a photosensitive polarizing film (B). Since the molecules which constitute the photosensitive polarizing film (B) are uniaxially oriented, the film (B) has polarizing ability. Then, the photosensitive polarizing film (B) is irradiated with light through a photomask, decomposition of the polymer which can be decomposed with light occurs in the irradiated part. By developing the film having the decomposed polymer, a positive pattern corresponding to the part not irradiated with light is formed. The molecules in the positive pattern maintain the orientation state generated when the film is formed. Therefore, the positive pattern has the same polarizing ability as in the process of pattern forming.

Title: Liquid crystal display device
Inventor: SUZUKI YUKIO
IPC: G02F1/13357
Filed: 1996-03-04
Abstract: PROBLEM TO BE SOLVED: To make illuminance unevenness not to be caused at the time of irradiating liquid crystal elements with light beams from a light source. SOLUTION: At the time of irradiating the back surface of liquid crystal cells 12 with light beams from the light source, the light beams from the light source are spectrally splitted into a P-ploarized component and an S-polarized component by a beam splitter and light beams having respective splitted polarized components are superposed on a fly eye lens 9 from directions different with each other to be synthesized and respective light beams of the superposed luminous flux are emanated toward a Fresnel lens 11 according to respective incident angles by the fly eye lens 9 and then the light beams emanated from the fly eye lens 9 are condesed toward the liquid crystal cells 12 by the Fresnel lens 11.  Consequently, even though the density of the light beams from the light source is larger in the center part than in the peripheral part of the lens 9, the density of the light beams is mitigated by respectively emanating respective light beams by the fly eye lens 9 and thus the illuminance unevenness in the liquid crystal cells 12 is prevented from being generated.

IPC: F04C29/00
Filed: 1983-04-22
Abstract: PURPOSE:To reduce the costs of material and labor remarkably by a method wherein the rolling piston is formed by an inexpensive iron-carbon series alloy material and only the outer peripheral surface or only the outer and inner peripheral surfaces are hardened by induction hardening. CONSTITUTION:The rolling piston 10 is made of iron-carbon series alloy and is fitted to a guide rod 11 to throw the whole of the work into a high-frequency heater 12 and a cooling liquid sprayer 13 continuously. According to this method, hardened layer is produced on only the outer peripheral surface with a short period of time. The rolling piston is incorporated together with an upper bearing 14 and a lower bearing 15. The hardnesses of the inner peripheral surface and both side surfaces are the same as the hardness of raw material, therefore, working time may be shortened. The hardening of the outer peripheral surface of the rolling piston 20, which is effected by the high-frequency heater 22 and the cooling liquid sprayer 23, as well as the hardening of the inner peripheral surface, effected by the high-frequency heater 24 and the cooling liquid sprayer 25, are applied at every times when the piston 20 advances one step on an automatic transfer line 21.
