Title: Production of active matrix substrate
Inventor: NAGAYAMA KOHEI
IPC: G02F1/1368
Filed: 1999-04-20
Abstract: PROBLEM TO BE SOLVED: To decrease the probability of causing short circuit between a gate line and an auxiliary capacitance line due to failure in pattern forming by removing a part of a metal film between the gate line and auxiliary capacitance line and patterning the metal film into the gate line and auxiliary capacitance line. SOLUTION: When through holes for ion doping of a semiconductor layer are formed in a metal film in the process of forming an active matrix substrate 18, the metal film is preliminarily removed in first and second removing regions 57a, 57b between a gate line 12 and an auxiliary capacitance line 36, and then the metal film is patterned to form the gate line 12 and auxiliary capacitance line 36 while a gate electrode 33 and various kinds of wirings are formed. Thus, the first and second removing regions 57a, 57b can be etched two times in two photolithographic processes without increasing the number of production processes, and therefore, the probability of causing a short circuit between the gate line 12 and the auxiliary capacitance line 36 due to failure in pattern forming can be decreased, and the production yield of the active matrix substrate 18 can be improved.

Abstract: PURPOSE: To change the resonance frequency of the actuator in accordance with the driving frequency by slidably providing the sub-piston to change the capacity of the actuator in the actuator body.  
     CONSTITUTION: The sub-piston 7a, 7b to change the capacity of the actuator are slidably provided in the actuator body 2.

Abstract: PURPOSE:To put the automatic focusing device in focus on an optional body on a screen, to prevent defocusing, and to widen the width of photographic technique by rotating a control motor and turning a distance measuring instrument to a desired direction. CONSTITUTION:The distance measuring instrument 11 consists of a light emitting element 14, a light receiving element 15, a projection lens 16, a condenser lens 17, etc., and its projection angle can optionally be varied by a driving device such as a stepping motor.
