Abstract: The present invention uses a material that is not conventionally used in fountain pen nibs in order to provide a fountain pen nib that is completely different from the prior art. This found pen nib comprises one of corundum, topaz, emerald, and garnet as a main material. It is also possible to replace the heart hole and the slit of the nib with a groove that is added to the rear surface of the nib. By using one of the abovementioned gems as the main material in a faun-tain pen nib, it is possible to achieve wear resistance and chemical resistance in the fountain pen nib while imparting a luxurious feel and originality to a fountain pen.

Abstract: The present invention provides a method for producing a product with a constant weight made from a compressible fluid which comprises feeding the compressible fluid into a prescribed vessel, characterized in that the volume of the compressible fluid to be fed into the vessel is adjusted according to variations of specific gravity of the compressible fluid to be fed into the vessel so that the weight of the compressible fluid to be fed is constant.

Abstract: The present invention provides a toilet bowl flushing water tank device which can prevent the easy increase of a supply quantity of flushing water to a toilet bowl exceeding a predetermined quantity.

Abstract: An apparatus for producing a soap cake comprising a mold which has a cavity of prescribed shape, a feed passage for feeding molten soap to the cavity, and means for pushing molten soap remaining in the feed passage at the time of feeding molten soap to the cavity to remove molten soap remaining in the feed passage. One end of the feed passage is a gate, in which a gate pin for shutting the connection between a feed port and the cavity is slidably provided. As the gate pin advances, molten soap remaining in the feed passage is removed in the step of feeding molten soap to the cavity.

Abstract: An absorption refrigerator includes a generator for separating, by vaporization, a refrigerant from an absorption solution, a condenser for liquefying by condensation the vaporized refrigerant, an evaporator for vaporizing the liquefied refrigerant from the condenser by heat exchange with a heat medium, and an absorber for absorbing the vaporized refrigerant to react against the absorption solution to be supplied from the generator. The evaporator has heat exchanger pipes disposed in the vertical direction and refrigerant discharge nozzles for discharging the refrigerant toward the inner walls of the heat exchanger pipes. Each of the refrigerant discharge nozzles is arranged at a position displaced downward by a predetermined distance from the upper end of each of the heat exchanger pipes.

Abstract: A system and method for registering a password includes a data center that processes and stores transaction data, and a teller window transaction device communicating with the data center. The teller window transaction device has a first input device such as a keyboard used by a teller for inputting transaction data, a first display unit used by the teller for displaying the transaction data, a second input device such as an input panel used by the customer, and a second display unit used by the customer for displaying the transaction data. When a new customer's card is issued, the first input device is used by the teller for inputting information such as the customer's name and address, and this information is shown on the second display unit as well as the first display unit so that the customer can confirm that it has been accurately entered. Thereafter the customer is prompted to use the second input device to enter a secret password, which has not been disclosed to the teller.
