Method of cultivating mushrooms

The invention provides novel strains of Basidiomycetes and more particularly, novel strains of Lyophyllum ulmarium. The novel strains are characterized by having a cap which is not concave when the fruiting body has matured. A process is provided comprising inoculation of Lyophyllum ulmarium with a cap which is not concave when the fruiting body has matured on a medium to form the fruiting body. Also provided is a method comprising the mating of Lyophyllum ulmarium Lu 1-8 with other Lyophyllum ulmarium and the harvesting of Lyophyllum ulmarium with a cap which is not concave when the fruiting body has matured in a term of cultivation up to harvest of the fruiting body that does not exceed 100 days.

This invention relates to an electromechanical transducer type relay which opens and closes contacts using electromechanical transducer elements, such as electrostrictive elements or piezoelectric elements, which produce strains when subjected to an electric field.

Electromechanical transducer type relay

A drive circuit of a two-laminated electrostriction element, wherein a common junction of two sheets of electric distortion elements is connected to one of the driving power source through a first switching means, and the other terminal of the one electrostriction element is connected to the other of said driving power source, with the other terminal of the other electrostriction element being connected to a second switching means, thereby to rotate the other electrostriction element by the voltage charged in the one electrostriction element.

A drive circuit for a piezoelectric actuator includes a pair of power input terminals for supplying either AC or DC power, with the piezoelectric actuator being connected between these power input terminals. A device for supplying current for driving the piezoelectric actuator in one direction is interposed between one of the power input terminals and an end of the piezoelectric actuator. Further, there is provided connected in parallel to the piezoelectric actuator a switching circuit which turns into a high resistance state when the device is on and serves as an active discharge path for the electric charges of the piezoelectric actuator.

This multi pole relay includes: a base plate; several bimorphic elements each of elongate plate shape and including a central electrode of elongate plate shape, a pair of piezoelectric members of elongate thin plate shape arranged on opposite sides of the central electrode, and a pair of surface electrodes arranged on the outer surfaces of the pair of piezoelectric members; a means for fixedly mounting the one ends of the bimorphic elements to the base plate with their other ends free; and, for each one of the bimorphic elements: a fixed contact mounted to the base plate opposing the free end of that one of the bimorphic elements; a flexible element, one end of which is mounted to the base plate, and the other free end of which is interposed between the free end of that one of the bimorphic elements and the fixed contact; and a movable contact mounted on the free end of the flexible element on its side towards the fixed contact and opposing the fixed contact. Thereby, the relay may be made very compact and of very low profile, and accordingly is suitable for fitting to a printed circuit board in conjunction with integrated circuits.

Multi pole piezoelectrically operating relay

This relay has an actuator which has a pair of coupled together driving elements, of a type which deflects according to applied voltage. The actuator deflects in one direction when voltage is applied to one driving element and deflects in another direction when voltage is applied to the other driving element. A bistable switching mechanism has an actuating member and a set of contacts. These contacts are flipped over to a first state when the actuating member is impelled in a first direction and thereafter stay stably in the first state until the actuating member is impelled in a second direction, and similarly are flipped over to a second state when the actuating member is impelled in the second direction and stay stably in the second state until the actuating member is impelled in the first direction. A drive circuit upon command supplies a one shot pulse of relatively short duration to either the one or the other of the driving elements. The actuator is coupled to the actuating member of the bistable switching mechanism, so as when deflecting in the one direction to impel the actuating member in the first direction, and when deflecting in the another direction to impel the actuating member in the second direction. Optionally, the coupling between the actuator and the actuating member of the bistable switching mechanism may have a certain amount of play provided in it, and the driving elements of the actuator may be piezoelectric elements.
