Patent JP-H09295344-A (JP)
Title: Manufacture of thermoplastic resin film
Inventor: MIYAGAWA KATSUTOSHI
IPC: B29K67/00
Filed: 1997-03-04
Abstract: PROBLEM TO BE SOLVED: To provide not only a longitudinal orientation method with a small coefficient of contraction in width, but also a manufacture with a reduced physical unevenness in width after the biaxial orientation, good thickness uniformity, and excellent productivity. SOLUTION: The manufacture of a film is such that after a first orientation is executed, a biaxial orientation is performed by executing a second orientation in the direction normal to the first orientation and thus the orientation of a thermoplastic resin film is done by the use of a file where a film from factor D before the first orientation is 3 or lower. However, the film from factor D is to be a rate (de/dc) of an average thickness (dc) of the film central part with respect to the maximum thickness (de) of the film end part. In this manner, a coefficient of contraction in width becomes small in its orientation in the longitudinal direction, and physical unevenness in the width direction of the biaxially oriented film is small, so that the uniformity of the thickness is significantly improved in order to retain high productivity.

Title: Trouble detecting circuit for adder
Inventor: KAGA TAKAHIKO
IPC: G06F7/499
Filed: 1986-03-07
Abstract: PURPOSE:To contrive the diagnosis of an adder by supplying the output of a counter to both inputs of an adder in a diagnosis mode and comparing the output of the adder with the value obtained by doubling the output of the counter in an addition diagnosis mode and with '0' in a subtraction diagnosis mode respectively. CONSTITUTION:A counter 1 is actuated by the clock similar to that which actuates an adder 8 and inverts the value of an addition register 2 in a carry-out mode. When the value of the register 2 is equal to '1', a selecting circuit 6 gives the output of a 1-bit left shifter 5 to a comparator 7 for comparison between the double value of the counter 1 and the output of the adder 8. Here the output of the counter 1 is applied as it is to both inputs of the adder 8 via selecting circuits 3, 32 and 4. Thus the diagnosis of an addition mode is carried out. When the output of the register 2 is equal to '0', the circuit 6 gives '0' to the comparator 7 and at the same time the circuit 4 gives the complement of the value of the counter 1 to the adder 8. Thus the diagnosis of a subtraction mode is carried out.
