Title: Liquid crystal shutter and printer head using the shutter
Inventor: TOKO YASUO
IPC: B41J2/445
Filed: 1999-03-25
Abstract: PROBLEM TO BE SOLVED: To obtain a liquid crystal shutter, in which the time for optical writing can be reduced, by forming a dot matrix for the liquid crystal shutter, subjecting the surface of the liquid crystal layer side of a substrate having a transparent electrode to aligning treatment with light and aligning the liquid crystal molecules perpendicular to the substrate plane, when no voltage is applied on the liquid crystal layer. SOLUTION: The-Light emitted from a light source 22 passes through a light-transmitting plate 21 and introduced into a liquid crystal shutter 10. By controlling each dot of the liquid crystal shutter 10, the light to irradiate a photosensitive film 40 is controlled to be turned on/off. The printer head 20 consists of a planer dot matrix to expose a large area of the photosensitive film 40. Thus, printing time can be significantly reduced. The liquid crystal shutter 10 is a perpendicular alignment type. Thereby, a black state, namely the light-shielding property by a pair of polarizing layers can be further improved. By aligning the liquid crystal layer by alignment treatment with light, the light-shielding property is further improved.

Abstract: PURPOSE:To perform quick balancing with even abrupt variation in atmospheric pressure and to prevent intrusion of the dust, by balancing the pressure in a closed container with the external pressure through an expandible bag body. CONSTITUTION:A closed container 1 containing a magnetic disk device communicates with an atmospheric pressure balancing device 2 through a communicating tube 7. The container 2a of the balancing device 2 communicates with the atmospheric pressure through an outside air communication tube 8. The closed container 1 keeps pressure balance with the outside air through the bag body 13 such as bellows having a return spring 14 which expands and contracts according to the pressure in the container. Further, a filter 9 is provided in a communication hole for the communication between the inside of the bag body 13 and the outside air; this filter has large dust filtering effect even if its air resistance is large. Abrupt variation in pressure is dealt with by the expansion and contraction of the bag body 13, which returns at a low speed to its initial position by the return spring body.
