Title: Locking device for architectural motor-driven shutter
Inventor: KOYANO AKIRA
IPC: E06B9/86
Filed: 1996-12-06
Abstract: PROBLEM TO BE SOLVED: To shorten a necessary current-application time to a solenoid, by connecting the solenoid to a locking tool, which is in the locking state at the no-current application condition and in the unlocking state at the current application condition and stopping a latch at the nearby position of the locking tool where it exceeds the locking position by the current application of the solenoid. SOLUTION: When a shutter curtain in the opened condition is shut, a latch pushes a locking tool 7 at a little forward position of the completely closed position and the solenoid 9 gets to a non-excited state at the lower side position thereof and gets to the locking condition restricting only the unlocking side movement of the locking tool 7. When actuating to open the shutter curtain by an opening switch in the state the exciting iron core 9a is retracted, the locking tool 7 is moved upward by the contact of the latch and hence, the locking tool is unlocked. In this case, the electricity to the solenoid 9 is supplied for a timer time a little exceeding the actuation time until the shutter curtain rises to the position exceeding the locking tool 7 from the completely closed condition.

Filed: 1998-12-03
Abstract: PROBLEM TO BE SOLVED: To make it possible to decrease the splitting defects in a splitting stage by the arrangement constitution of columnar film spacer patterns arranged in the spacing between an array substrate and a counter substrate.
