Title: Cross flow type blower
Inventor: TAKUSHIMA AKIRA
IPC: F04D17/04
Filed: 1989-05-08
Abstract: PURPOSE:To reduce disturbance of air and to improve efficiency by a method wherein, in a cross flow type blower, protrusion parts are formed on a front plate on the air suction port side, an inner part, and the inside of a rear plate. CONSTITUTION:Since an air delivery passage 6 is ensured within a limited depth W of a casing 2, a passage adjacent to an impeller 4 and curved in an arcuate shape is formed. But, since an air suction port 5a of an air suction passage 5 is sized to be equal to the depth W of the casing 1, it is in an excessively widely opened state. By forming protrusion parts 2a and 3a in parallel to the rotary shaft of the impeller 4 on both the inner part of the front plate 2 of the air suction passage 5 and on the inner part of a rear plate 3, the air suction port 5a of the air suction passage 5 is substantially decreased in size. This constitution improves the flow of sucked air, and reduces disturbance of a space above the impeller.

Abstract: PURPOSE: To enable positive type color display using guest-host effect to be performed by twist-orienting the liquid crystal of the segment parts and homeotropic- orienting the other portions.  
     CONSTITUTION: Since the liquid crystal 9 of the parts provided with segment electrodes 6 of a display panel 4 is twist-oriented in a no-voltage-applied state, the color of a dye is visible to the observer. On the other hand, the liquid crystal 9 in the parts other than the display segments 6 is homeotropic-oriented in a no-voltage- applied state, hence it appears colorless to the observer. After all, the ground is colorless and transparent and all the segments are color-displayed in the no-voltage- applied state. To display figures, voltage is applied to the segments unnecessary for the displaying out of the display segments 3 to homeotropically orient said parts, whereby they are made visible like the ground. Since the voltage is applied to the  unnecessary segments only, the positive displaying of low power consumption is performed.
