A treatment catheter is used which is equipped with two inflatable balloons which seal off a constriction place in a vessel on both sides thereof whereb...

PURPOSE:To obtain a sufficient operational margin even by dividing finely and to make the compact integration without degrading the performance by controlling the storage of the charges to the floating gate of a transistor and storing a bit of information by the changes in the threshold voltage of a control gate. CONSTITUTION:In a MOS semiconductor memory, a memory cell consists of a first MOS tra...

A controlled amount of a solder is applied to the tip (18) of each lead (14) of a multi-lead component (10) by first placing a solder sphere (30) in each of a plurality of cavities (24) arranged in a baseplate (22) in the same pattern as the tips of the leads. Thereafter, the tips of the leads of the component are placed in contact with the solder spheres while, at the same time, at least a pair o...

In operation of a screw extruder, particularly a pin extruder, processing a rubber or a plastic mixture, troubling disturbances and on occasion heavy damage occur when foreign bodies are introduced into the extruder with the material to be processed causing damage to the extruder structure. In order to avoid this damage one possibility is to shut off the extruder at a sufficiently early time and o...

According to this invention, a limited multicast communication notice indicating that an identical message is transmitted to a plurality of arbitrarily designated stations is transmitted prior to transmission of a text message. The notice includes definition data. The notice is received by a data input/output section, and it is checked by a comparator if the notice is a message destined to be sent...

METHOD AND APPARATUS FOR ENCODING SPEECH In a speech encoder a Fourier transform of the speech is provided. The Fourier transform is equalized by normalizing the spectrum coefficients to a curve which approximates the shape of the spectrum. Both the curve and the equalized spectrum are encoded. Preferably, only a baseband of the normalized spectrum is encoded and that baseband is repeated in the d...

A method of producing heat strengthened glass (l) in which the glass (l) is heated to a temperature above its strain point and is then cooled while horizontally supported. Discontinuous support (2) is provided for the glass (l) as it is cooled by intermittent regional contact with the lower surface of the glass (l), whereby any pattern of iridescence resulting from heat transfer between the lower ...

A method of manufacturing packages for LSI chips starts with the usual steps of punching holes in green sheets, screening patterning paste (adapted to form cermet conductors or the like after firing) onto the green sheet, and inspecting the green sheets optically. Here, subsets of green sheets are then stacked and compressed into sublaminates. The sublaminates are then functionally inspected elect...
