Abstract: An apparatus for preventing transferring noise of a digital signal comprises, a noise-transfer preventing circuit 11 which transfers a signal D whose potential represents data to be transferred originally in binary data and a signal DB whose potential represents the other data at the same time, inputs the signals D and DB at an input block 10 side, outputs one signal D as an input signal as a normal state when the signals D and DB are the potentials representing different data "1" and "0", and when the signals D and DB are the potentials representing same data, continues to output the signal previously outputted as the input signal as an abnormal state, whereby, at the time of transferring the digital signal, it can be avoided to transfer the level change according to fluctuations of the signal potential or the signal change on the other signal lines as the dat signal.

Abstract: A microcomputer in which a monitor Read Only Memory (ROM) 100 having a monitor sense amplifier circuit 113 whose normal operation range for power voltage is set narrower than that of the sense amplifier circuit 130 of the ROM 20 is provided, and the sense amplifier circuit 130 of the ROM 20 is constructed so as to has a plurality of sense amplifier circuit portions and a switching circuit portion to obtain an optimum operation range for a plurality of power voltages by switching the circuit characteristic according to a signal supplied from the monitor ROM 100. The sense amplifier circuit 130 is switched to obtain an optimum operation range for a plurality of power voltages, or the frequency of the system clock E can be switched, by detecting such a state wherein the power voltage decreases or the frequency of the system clock E increases to reach near the operation limit.

Abstract: A double layer capacitor with electrodes produced from a carbonaceous material having a large capacitance obtained by heat-treating an activated carbon precursor at a temperature below 700.degree. C., preferably from 400.degree. to 500.degree. C., in an alkali metal hydroxide bath. In particular, its capacitance per unit volume is several times larger, in some cases 7 or more times larger, as compared with conventional activated carbons for capacitors.

Abstract: A microcomputer including first, a voltage change circuit which includes circuitry for selecting one of two voltages applicable to a PROM and, second, leak current prevention circuitry for preventing a current from leaking from a first terminal at a first voltage through first and second switching elements to a second terminal. The leak current prevention circuitry can be a transistor whose source, drain and gate are tied to the first terminal, to the gate of the second switching element and to the second terminal, respectively. The leak current prevention circuitry operates to cut off the second switching element which the voltage at the second terminal is zero. The circuitry for selecting can be two series circuit, each consisting of a diode and two transistors. The series circuits are interconnected and responsive to a voltage selecting signal.

Abstract: Medical appliances are continuously packed for sterilization thereof by the process wherein (1) bags having micropores in peripheral side portions thereof to be sealed, which micropores allow passage of a sterilizing gas and a high pressure steam but do not allow passage of germs, are formed from packing sheets; (2) medical appliances are inserted into the bags while the bags are formed; (3) all the peripheral side portions of the bags are sealed; and (4) the sealed bags containing the packed medical appliances are separated into packages each having the packed medical appliance.

Abstract: Nonwoven fabrics are made by continuously expelling a high pressure liquid jet stream in the form of a film through a slit-shaped nozzle onto a web placed on a support.

Abstract: A detector to be inserted into a flowing conductive fluid, e.g. sodium coolant in a nuclear reactor, comprising at least one exciting coil to receive an a-c signal applied thereto and two detecting coils located in the proximity of the exciting coil. The difference and/or the sum of the output signals of the detecting coils is computed to produce a flow velocity signal and/or a temperature-responsive signal for the fluid. Such flow velocity signal or temperature signal is rectified synchronously by a signal the phase of which is shifted substantially .+-. 90.degree. with respect to the flow velocity signal or temperature signal, thereby enabling the device to detect voids in the flowing fluid without adverse effects from flow velocity variations or flow disturbances occurring in the fluid.

Abstract: A filamentary strand of a thermoplastic nature is ejected from an ejection nozzle being entrained on a heated medium flow into a stuffing chamber structured on a circulating endless surface moving at a speed slower than the ejection speed and the stuffed filamentary strand is transported, being carried by the endless surface, towards a downstream outlet of the stuffing room in such a way that the yarn mass is gradually compressed during displacement toward the downstream outlet of said stuffing room. During the transportation either a free or a positive cooling is employed. The resultant filamentary strand is provided with random, bulky and round three-dimensional crimps.

Abstract: The present invention provides an apparatus, and a method for the regeneration of spent wet active carbon, which apparatus comprises a drier for substantially drying the spent carbon, a heating furnace provided with at least one burner and at least one duct, and a regeneration chamber consisting of at least one set of inner cylinder and outer cylinder installed concentrically and vertically inside said heating furnace to penetrate the top and bottom walls of the furnace, wherein said inner and outer cylinders have respectively a multiplicity of holes penetrating the side walls thereof, said inner cylinder is connected with a supply tube for a regeneration gas capable of effecting regeneration of the dried carbon-to-be-regenerated upon contact therewith, the upper end of said outer cylinder is connected with said drier so as to receive said dried carbon therefrom while the lower end thereof forms an outlet for the regenerated carbon, and said duct is connected with the drier so as to facilitate direct or indir

Abstract: The apparatus comprises an outermost, an intermediate, and an innermost compartment, the outermost compartment being provided with burners, activated carbon being supplied into, treated in, and removed from the intermediate compartment, and there being communication for gas between the three compartments. In revivification by the direct heating process, reactor gas is supplied into the outermost compartment, heated by the burners, passed into the intermediate compartment to contact the activated carbon being treated, and is then passed into the innermost compartment and exhausted therefrom. In revivification by the indirect heating process, reactor gas is supplied into the innermost compartment, passed into the intermediate compartment for treatment of activated carbon, and then passed into the outermost compartment and is exhausted therefrom, the innermost and intermediate compartments and elements therein being indirectly heated by the burners of the outermost compartment.
