Abstract: There is provided a mobile terminal capable of being protected against unauthorized use by a third party without using a dedicated key device. A plurality of mobile terminals are previously registered mutually. When unlocked among them, one mobile terminal communicates with another mobile terminal in a communication range of short-range wireless communications, unlocks the above another mobile terminal, and when out of the communication range, locks it again.

Abstract: A shutter assembly for a bay window to close an opening by moving a shutter curtain upward from a containing space in the bottom of the bay window and to open it by way of a downward movement of the curtain under the influence of a coil spring. The basic driving system for the shutter is located either in the roof or in the lower containing space of the bay window. Various devices are disclosed including a seal for sealing the space between the leading member of the curtain and the roof of the bay window, a structure for installing the driving motor, a structure for detachable connection of the driving shaft, hainging members used to raise and lower the curtain, a structure for supporting the winding drum on the driving shaft, as well as features to allow maintenance of the shutter assembly.

Abstract: An ultrasonic burner system for regenerating a filter comprises an ultrasonic atomizer for atomizing fuel oil into fine droplets and a combustion chamber that is adapted to pass a exhaust gas created therein by the combustion of the fine droplets toward the filter to regenerate the filter by burning previously unburnt matter trapped thereby, wherein the fine droplets are burned in such a manner that the exhaust gas is at a higher temperature in the wall region than in the axially central part of the combustion chamber. Consequently, the combustion chamber can be made compact, and since the temperature of the combustion gas flowing in the combustion chamber is made higher in the wall region than in the axially central part of the combustion chamber, the temperature distribution in the filter can be made uniform.

Abstract: An ultrasonic injection nozzle includes an ultrasonic vibration generating device and a vibrating element. The vibrating element; connected to the vibration generating device so as to be vibrated thereby. The vibrating element has formed at its forward end an edged portion to and along which a liquid material is delivered to be atomized.

Abstract: The present invention is directed to the combination of a vibrating element and an ultrasonic nozzle having an ultrasonic vibrator. The combination includes a body having a liquid supply passage therethrough and a chamber having a first and second end. The liquid supply passage is in communication with the chamber via its first end. The second end of the chamber defines an opening. An inner peripheral wall forms a portion of the chamber intermediate the first and second end. A multistepped edged portion is formed on the inner peripheral wall and each step defines an edge which severs and atomizes the liquid which cascades thereover from the liquid passage.

Abstract: This invention consists of a vibration element for use on an ultrasonic injection nozzle, the vibrating element being formed around its outer periphery with a multi-stepped edged portion having one or more projecting steps each defining an edge, the edges having the same diameter and the edged portion being adapted to be supplied with liquid.

Abstract: An ultrasonic injection nozzle includes an ultrasonic generator, an elongated vibrating element, a liquid feeder and a solenoid valve. The vibrating element has a first and second end. The generator is connected to the first end. A multi-stepped edge portion is connected to the second end. Each step of the edged portion defines an edge. The liquid feeder is located adjacent the second end. The solenoid valve is in communication with the liquid feeder.

Abstract: A hydrocarbon oil coking process in which the feedstock is initially preheated to a temperature below the cracking temperature of the feedstock, prior to contacting the feedstock with a flue gas obtained from the coking zone so as to preheat the feedstock to the desired coking temperature and thereafter coking the preheated feedstock at a temperature above the cracking temperature of the feedstock.
