Title: Back cover opening and closing safety device of camera
Inventor: YAMAGA SHIGERU
IPC: G03B17/02
Filed: 1978-09-29
Abstract: PURPOSE: To prevent the mis-opening of the back cover without impairing the rapidness of operation by so arranging the device that the locking of the back cover locking device is released when the button for releasing sprocket is pushed at the rewinding of film.  
     CONSTITUTION: On the way of photographing, a sprocket release button 14 is in a protruding state and a lock member 20 is in the position advanced onto the pass track of the step part 8 of a rewinding shaft 2. Hence, even if in this sate a rewinding knob 1 is pulled up owing to inadvertent catching of the hand or fingers thereto, said step part 8 abuts against the lock part 22 and therefore faulty opening of the back cover will not occur. Next, when the sprocket release button 14 is pushed in upon ending of photographing, the lock member 20 retreats to the outside of the pass track of the step part 8 of the rewinding shaft 2 by being pulled by a wire 25. Thereupon, the locking of the back wire is released and a patrone 6 may be drawn out.

Title: Data converting method
Inventor: KIMA HIRONOBU
IPC: G06F9/45
Filed: 1987-05-19
Abstract: PURPOSE:To eliminate the limitation inherent to the conversion of data which is caused by a DCG (definite clause grammar), by analyzing the structure of an input symbol string via the reduction processing carried out based on the structure of the input symbol string described in a conversion rule. CONSTITUTION:The structure of an input symbol string is described by a context free grammar method and at the same time a conversion rule which describes the structure of an output clause in relation to a termination symbol and a non-termination symbol is received from outside. Then the structure of the input symbol string is analyzing by the reduction processing carried out based on the structure of the input symbol string described by said conversion rule. An output clause is produced based on the description of the structure of the output clause related to both termination and non-termination symbols corresponding to the structure of the input symbol string. Thus it is possible to separate a dictionary from a grammar rule and to avoid the top-down type processing.

Filed: 1998-04-30
Abstract: PROBLEM TO BE SOLVED: To homogeneously heat a liquid crystal cell by constituting a heating system of an almost planar resistance layer, and providing electrodes capable of supplying a heating electric current to it. SOLUTION: A first electrode 21 and a second electrode 22 have a resistance layer 12 having a heating electric current. A connecting part 21c of the first electrode 21 is connected to negative electric potential of an electronic printed circuit board. A connecting part 22c of the second electrode 22 is connected to positive electric potential of the electronic printed circuit board. Therefore, the first electrode 21 acts as a cathode, and the second electrode 22 acts as an anode. In this way, the heating electric current flows to a linear leg part 21a (in the actual direction of the electric current) through an end part 21b from the first connecting part 21c of the first electrode 21. From here, the electric current is homogeneously distributed over the whole surface of the resistance layer 12 by an average method.  Therefore, homogeneous heat is generated, and a liquid crystal cell is very homogeneously heated. In this case, the electric current flows backward to the second connecting part 22c of the second electrode 22 through a linear leg part 22a and an end part 22b.
