Filed: 1983-11-09
Abstract: PURPOSE:To obtain an oscillation frequency corresponding to a digital input without providing any D/A converter by switching the current source or capacity of an emitter-coupled VCO circuit directly with a digital input. CONSTITUTION:When switches 36, 38, 40, and 42 are open, the oscillation frequency (f) of this circuit is I/4CVBE, where I is the current value of the constant current sources 32 and 34 of the emitter-coupled VCO circuit, C is the capacity of a capacitor 30, and VBE is the base-emitter on voltage of a transistor. Therefore, the current value I is varied by opening and closing the switches 26 and 38 of constant current sources 44 and 46 with the digital input or opening and closing the switches of other constant current sources 48 and 50, thereby varying the oscillation frequency. Consequently, the digital input is supplied directly to vary the oscillation frequency. Further, values of the capacity C are switched according to the digital input to obtain the same result.

Abstract: PURPOSE:To reduce the man-hour for painting and to improve the mass- productivity by arranging resonance element throughholes in parallel along the lengthwise direction, forming the dielectric block between the throughholes, packing a packing agent in a coupling hole and immersing the dielectric block into a bath made of an electrode forming material of a conductive paste. CONSTITUTION:Throughholes 4 for plural resonance elements are arranged in parallel along the lengthwise direction and a dielectric block 2 formed with a coupling hole 6 between each throughhole 4 is formed. Then a packing agent 20 is packed in the coupling hole 6 and the dielectric block 2 is immersed in a conductive paste bath made of an electrode forming material. After the immersing, the conductive paste is baked and succeedingly, the electrode film on the end face of one opening of the throughholes 4, 6 is removed by polishing or the like to form an open end face 14. Thus, an inner conductor 8 is formed on the inner face of the resonance element throughhole 4 and an outer conductor 10 is formed on the outer face of the dielectric block 2 respectively. Thus, less man-hour than the finish of the brush painting of the conductor paste in a conventional manufacture is attained.

Title: Superconducting three-terminal element and manufacture thereof
Inventor: AKASAKI TATSUSHI
IPC: H01L29/808
Filed: 1987-08-24
Abstract: PURPOSE:To minimize the length of superconducting current flow and to control the superconducting current effectively, by making the upper semiconductor layer between electrodes, or in a partial region thereof, insulated or of opposite conductivity type through ion implantation or convergent ion implantation and by making it thinner than the semiconductor layer in a superconducting electrode section. CONSTITUTION:The upper surface of a channel semiconductor is entirely insulated by ion implantation using superconducting electrodes of a source 1 and a drain 2 as mask, and a channel layer 3 which controls superconducting current is thinned. In this method, a surface conducting layer is not formed which has been a problem in conventional methods and therefore, superconducting current passes through the semiconductor channel layer without leakage on a surface conductive layer, thus allowing effective control of superconducting current. This method is effective for the length L of electrode spacing less than 0.1mum; however, for L more than 0.1mum, a part of the upper channel semiconductor is insulated by use of convergent ion implantation into thin the channel layer.

IPC: C08L27/18
Filed: 1984-10-05
Abstract: Melt-shapeable polymeric compositions comprising a first fluoropolymer of relatively low crystallinity and a second fluoropolymer of relatively high crystallinity, especially a fluoropolymer obtained by irradiating a fluoropolymer which cannot be melt-shaped in the absence of other polymers. The first fluoropolymer is preferably a copolymer of tetrafluoroethylene and an perfluorinated comonomer, e.g. hexafluoropropylene or a perfluorinated vinyl ether. The second fluoropolymer is preferably tetrafluoroethylene which has been irradiated to a dosage of 2.5 to 40 Mrad. The weight ratio of the first to the second polymer is preferably 0.3:1 to 2.5:1. The compositions are melt-shapeable, and the resulting shaped products have a valuable combination of properties derived from both fluoropolymers. For example, the compositions are particularly useful for electrical insulation, especially as low loss foamed insulation in coaxial cables.
