Title: Propduction of biologically active plasminogen activated factor
Inventor: ARATHOON WILLIAM R
IPC: C12N9/48
Filed: 1987-06-05
Abstract: Biologically active human tissue-type plasminogen activator is produced in a host cell culture by removing from the medium of the culture all medium components which are detrimental to recovery and activity of the plasminogen activator. For example, cross filtration may be used to carry out medium exchange during culture, or the detrimental components may be removed prior to culturing. The cells retain their expression capability after exclusion of the harmful substances so that production of active plasminogen activator can be effected.

Filed: 1996-06-05
Abstract: PROBLEM TO BE SOLVED: To reduce the noise at a high speed operation of a semiconductor device by covering only the surfaces of inner power leads and ground leads of a lead frame with a material having a lower permeability than that of a main material of the lead frame. SOLUTION: The semiconductor device comprises power or ground leads 101, other leads 102 than those 101, mold resin 103, a semiconductor chip 104 and bonding wires 105.

Abstract: PROBLEM TO BE SOLVED: To use a comparatively inexpensive oscillator by generating a control signal by a communication signal transmitted through a network to control a clock signal varying device to vary a first clock signal a first oscillator generates to correct the tolerance of the oscillator. SOLUTION: At the time of a normal operation, an operation mode adjustment setting device 125 detects the presence/absence of the fault of the clock signal T2 of an oscillator 180.
