Abstract: A bistable zero insertion force connector assembly including one or more conductive contact members (12). Each conductive contact member (12) includes mating ends or contact arms having contact surfaces and a resilient central segment (18). Variable engagement means (32) cooperates with each conductive contact member (12) to displace the member from a first stable state to a second stable state and vice versa, with minimal force the member being maintained in the first or second stable states by means of stresses induced in the resilient central segment (18). In the first stable state the contact surfaces of the mating ends or contact arms are disposed in mating proximity to the contact surfaces of the device to be electrically connected therewith with zero force/zero contact while in the second stable state there is secured engagement between the respective contact surfaces. Wiping contact between the respective contact surfaces during transition between the first and second stable states enhances reliability of the electrical connection.

Filed: 1988-12-16
Abstract: The initiation of the polymerisation or copolymerisation of monomers which can be polymerised by means of free radicals has hitherto been effected by using various peroxides, but storage of these may be hazardous; in addition, the initiation must be carried out in the absence of atmospheric oxygen. The novel process is nonhazardous and can be carried out in the presence of oxygen. The polymerisation or copolymerisation is carried out in aqueous, optionally solvent-containing systems using a free-radical initiator which is prepared in situ in the polymerisation system by adding a peroxide-generating enzyme and one or more enzyme substrates in the presence of oxygen and decomposing the resultant peroxide to form free radicals. The polymers and copolymers can be used to produce coatings.

Abstract: The humidity within a chamber (1) is detected by a humidity detector (2) and the proportional value, integrated value and differentiated value of the difference between the detected humidity and a preset objective value are added (11) to produce an operation amount signal. A predetermined period is divided into a spraying time of oscillating the oscillator (13) of an ultrasonic humidifier (12) with an amplitude such as to generate a predetermined sprayed amount per unit time, and a non-spraying time of oscillating the oscillator with such small amplitude as generates no spray from the ultrasonic humidifier. The predetermined period is repeated and the spraying time in each fixed period is adjusted in response to the operation amount signal to keep the humidity within the chamber constant.
