Title: Panel shutter
Inventor: KONDO KOICHI
IPC: E06B9/06
Filed: 1997-05-08
Abstract: PROBLEM TO BE SOLVED: To improve the reliability of a panel shutter by arranging a roller for suspension on the outside of a chain arranged on the outside of a side end face of a panel and fitting a free end of the chain in a chain guide bar provided above the roller for suspension along a storage rail in play. SOLUTION: A panel linkage chain 3 is mounted on both sides in an upper part of a panel 2 through a pin, and a roller for suspension 25 is provided on its outside. Next, a chain guide bar 6 is provided above along a storage rail 4 to utilize a section between 8 side end face of the panel 2 and a bracket 5a on a side wall of a storage box 5 effectively. A free end part 3a of the chain 3 which meshes with a sprocket for driving panel 8 and is extended in the direction of panel storage is moored to the bar 6 in such a manner that it can move freely so that the chain 3 does not come off from the sprocket 8 when the panel is reeled out.  Moreover, since the free end 3a moves along the bar 6 when the panel 2 is stored, the length from a pin of the first panel 2 which moves on the rail 4 to the free end 3a is reduced, and it is possible to prevent great loosening of the free end side and twining of the chain.

Title: Liquid crystal display device
Inventor: KINJI KENJI
IPC: G09G3/36
Filed: 1985-05-31
Abstract: PURPOSE:To eliminate a flicker by regarding one horizontal scanning section which extends in a gate-line direction as one unit and inverting the polarity of a signal which drives liquid crystal. CONSTITUTION:The polarity of picture element electrodes of the 1st field to a common electrode is inverted successively in a data line direction while one column of picture elements which are arrayed in the direction of gate lines of an active matrix substrate and correspond to one horizontal scanning section is regarded as one unit, thereby writing a signal. Then, in the second field, the polarity is inverted every one column picture elements equivalent to one horizontal scanning section. Thus, the 1st field and the 2nd field are driven repeatedly at every vertical scanning section. Consequently, the number of picture elements which drive liquid crystal positively and that of picture elements which drives the liquid crystal negatively are equal between the 1st and the 2nd field to eliminate the difference in the quantity of light transmitted through a liquid crystal layer in total between the 1st and the 2nd fields, so no flicker is caused and the display quality is improved.

Title: Speed-control device for induction motor
Inventor: MIWA CHIKAHIRO
IPC: H02P23/00
Filed: 1978-09-28
Abstract: PURPOSE: To extend the speed control range without increasing a converter capacity and rating by connecting a secondary excitation control device to the secondary circuit of a motor and changing the number of poles to vary the synchronization speed.  
     CONSTITUTION: In the case a wire-wound-type induction motor 1' having the number of poles for two different synchronization speed is started, a breaker 2 for a low-speed winding is closed, and the secondary-excitation-control operation is made in a low-speed region. When a signal is given from a speed-reference signal generator 7 so as to operate at the r.p.m. higher than the low-speed region, the counter voltage of a counter converter 8 is decreased by amplifiers 13 and 14, the speed of the motor 1' which has been running with the low-speed winding is increased, and a speed sensor 17 senses that the maximum speed with the low-speed winding is reached. The resultant speed signal opens the breaker 2 and a contactor 5 to change the number of poles of the induction motor 1', then closes a breaker 18 for a high- speed winding and a contactor 19, and the similar secondary excitation control operation is carried out in the high-speed region, thereby the speed control range can be extended.
