Title: Perforated shrink film
Inventor: TSUJITA AKIO
IPC: B65D65/40
Filed: 1996-09-30
Abstract: PROBLEM TO BE SOLVED: To prevent ingress of harmful insects and dust, and to realize the excellent packaging finish by specifying the ratio of the total area of a plurality of holes for air vent of the prescribed diameter to the surface area of a film. SOLUTION: A perforated film for shrink-package is manufactured so that a plurality of holes for air vent of <=0.2mm in diameter are provided, and the ratio of the total area of the holes to the surface area of a film to be packaged is >=1/10000 and <=1/200. When the diameter of the holes is larger than 0.2mm, the effect to prevent dust and insects becomes small. When the ratio of the total area of the holes of <=0.2mm in diameter to the surface area of the film is <=1/10000, the air vent becomes insufficient. When the ratio of the total area of the holes to the surface area of the film is >=1/200, the air vent becomes too fast, the non-uniform shrink condition is easy to generate, and the packaging finish becomes defective, such as bubbles.

Title: Data signal phase correction system
Inventor: MORIMOTO AKIRA
IPC: H04L7/00
Filed: 1988-11-02
Abstract: PURPOSE:To reduce the probability of out of synchronism considerably by comparing a phase difference between an input data signal with a basic clock and giving a time delay to an input data signal so that the phase is a predetermined value or below. CONSTITUTION:When a time difference between an input data signal and a basic clock signal is T2, the time T2 is adjusted so that the overlapped time T2' between a timing time 2 of a variable delay output and a timing time 3 of a basic clock is at least a half the timing time 3 of the basic clock or over. Thus, out of synchronism caused by approaching of the input and output phases of an FIFO memory is not caused. The variable delay quantity T1 is adjusted optionally depending on the phase difference T2. Thus, the synchronization of the input data signal with the clock signal is taken.

Filed: 1997-10-13
Abstract: PROBLEM TO BE SOLVED: To facilitate not only the judgment of Pass-Fail but also the measurement of more detailed IDDQ value in an IDDQ (static leaking current) test. SOLUTION: A circuit tester is equipped with a power source output for supplying an electric power to DUT 105, and the output of the power source 301 is connected to DUT through a switch 304.
