Title: Multiplexer
Inventor: MORIMOTO AKIRA
IPC: H04J3/04
Filed: 1989-03-08
Abstract: PURPOSE:To use only one phase speed conversion section and to simplify the constitution of a multiplex circuit itself by setting a phase setting value to a line termination circuit, converting the phase speed of a data signal based on the phase setting value and giving a phase selection signal corresponding to the phase setting value. CONSTITUTION:A data signal is phase-converted at a phase preset at a setting section with a phase speed conversion section 4 and the result is outputted as a data signal as shown in figure (d). On the other hand, a phase selection signal (f) representing an inserted phase of the data signal is given to a multiplex section 6 from the setting section 8 and the multiplex section 6 multiplexes the data signal based on the phase selection signal. In this case, a different phase is set respectively to each setting section 8 provided to each line termination circuit 2. As a result, a phase selection signal given from each setting section 8 to the multiplex section 6 differs from each other. Thus, the multiplex signal shown in figure (e) is outputted from the multiplex section 6 to a signal output terminal 7.

Title: Manufacture of superconducting semiconductor device
Inventor: YAMAZAKI SHUNPEI
IPC: H01L39/24
Filed: 1987-03-09
Abstract: PURPOSE:To put a semiconductor device to practical use even when it is formed not at room temperature but by cooling, by a method wherein two or more semiconductor devices are formed inside a semiconductor substrate and a mutual wiring part on the semiconductor substrate is formed by using a ceramic material which displays the superconductivity. CONSTITUTION:Two or more devices, e.g. an insulated-gate fieldeffect transistor, a bipolar transistor, a SIT (a static induction transistor), a resistor and a capacitor, are formed, e.g., on a single-crystal silicon semiconductor substrate 1. A superconducting material which makes the electrical resistance zero or close to zero is formed on the devices or on an insulating film 2 on them or on a conductor. This material is etched selectively and patterned. Furthermore, if, prior to this process or after it, a thermal annealing process is executed at 500-1000 deg.C especially in an oxidizing atmosphere, the crystal structure of a ceramic material is transformed in such a way that it displays a superconducting phenomenon at a very low temperature. If these processes are executed once or repeated two or more times, a mutual wiring part at a layer or between individual layers can be formed by using the material whose electrical resistance is zero.

Abstract: PURPOSE:To decrease the take-out current of a battery by connecting a heater for heating catalyst, etc., to an alternator side from the connecting parts of an electrical loading battery to the alternator and electrifying the heater by means of output of the alternator. CONSTITUTION:A catalyst 4 with a heater, a stator 5 and a vehicle load 6 are wired from a battery 1 and an alternator 2.

The electrification current to the catalyst 4 with the heater (terminals e', e'', f', f'') becomes the take-out current from the alternator l and the battery 1. The state where the generated output of the alternator 2 is large is kept, so that the take-out current from the battery 1 may not be easily increased. Accordingly, the take-out current from the battery 1 may be small, so that the life of the battery is prolonged.
