Abstract: An automated machine for and the method of fabricating containers made from a cardboard paperboard or corrugated paperboard blank having an inner liquid holding bag secured to the inner surface of the paperboard box. The liquid holding bag includes a spout that extends through a spout opening formed in the paperboard blank.

Abstract: The present invention provides a multilayered ceramic substrate having high precision and high reliability in which firing shrinkage in the planar direction thereof is suppressed and densification is achieved. The multilayered ceramic substrate is manufactured by laminating base layers each composed of a non-glass type low-temperature sintering ceramic raw material powder as a main component, and shrinkage inhibiting layers each composed of a sintering-resistant powder of alumina or the like as a main component to form a green ceramic laminate, and then firing the green ceramic laminate at the sintering temperature of the low-temperature sintering ceramic raw material powder. The shrinkage inhibiting layers contain a powder which does not soften and flow at the firing shrinkage start temperature of the low-temperature sintering ceramic powder, but permeates into the spaces of the sintering-resistant powder due to softening and flowing to densify the shrinkage inhibiting layers before sintering is completed.

Abstract: A fuseless DC-DC converter is provided to protect a circuit from overcurrent without involvement of a protective fuse. This is accomplished by providing a load circuit in the converter that includes a first overheat self-interruption-type semiconductor switch in series between a DC power supply and a load, and a reference circuit including a second overheat self-interruption-type semiconductor switch in parrallel with the first switch, and a reference resistor with one end connected to the source of the second switch, and the other end grounded. Also included is a comparator circuit that compares the source voltage of the first switch with a reference voltage applied to the source of the second switch, and thereby determines if the circuit has overcurrent. If overcurrent is detected, the results from the comparator circuit are used by a power supply controller to deactivate the semiconductor switch.

Abstract: A power supply control unit of this invention has a stabilized power source by a DC/DC converter and a Zener diode for supplying selectively plural voltages and supplies a power to a current vibration type shut-off function provided switching circuit. When power supply from a power source to a low voltage load is controlled via switching by a temperature sensor incorporated FET, a reference voltage having a voltage characteristic equivalent to that of a voltage between terminals of the temperature sensor incorporated FET to which a predetermined load is connected is generated by a reference FET and a resistor. A difference between a voltage between the terminals of the temperature sensor incorporated FET and the reference voltage is detected by a comparator. Then, the ON/OFF of the temperature sensor incorporated FET is controlled depending on a difference between the voltage between the terminals and the reference voltage by a driving circuit.
