Filed: 1986-07-17
Abstract: PURPOSE:To form simply and exactly very fine throughholes having uniform diameters and being crowded highly densely in a polyolefin resin film, by stretching the film, forming throghholes in the film with laser beam and restoring its stretch to an original state by heating. CONSTITUTION:A polyolefin resin film is stretched, through-holes are formed in this film with laser beam, and the stretched film is restored to an original state by heating. Because of their good suitability for stretching, high-density polyethylene, linear high-density polyethylene and polypropylene are desirable as said polyolefin resins. The stretch may be unidirectional or biaxial. The stretch ratio is preferably 1.5-20 and heat set after stretching is not performed.

Title: El light emitting device
Inventor: SATO YOSHIHIDE
IPC: H05B44/00
Filed: 1990-06-28
Abstract: PURPOSE:To control the gradation of light emission for an EL light emitting element due to voltage modulation with simple circuit configuration by charging the EL light emitting element and controlling the amplitude of a voltage to be impressed to the EL light emitting element according to time for charging. CONSTITUTION:A data voltage VD of a positive polarity for driving an EL light emitting element CEL is a value dividing a charge amount, for which charging time (t) is multiplied to a constant current ID to be supplied from a constant current source 5, with capacity CEL of the EL light emitting element CEL. Therefore, the voltage VD is the variable of the time (t) and by controlling the time (t) by a counter circuit 3, the correspondent voltage VD is outputted. Simultaneously with the start of counting a gradation data signal to be inputted to the circuit 3 by a clock, a control pulse is made 'L' and when ending counting, the control pulse is made 'H'. Therefore, the period when the control pulse is 'L' becomes the period (t). The voltage VD at such a time linearly rises up and by turning a reset switch 4 on, the voltage falls down.
