Abstract: A key top comprising a key stem provided at a lower portion of the key top to be inserted into a rubber cup unit; and a first spring provided at a lower end of the key stem, and comprising a plate spring, wherein the key top is pushed down by finger pressure to turn on a contact point, thus executing key-in operation.

Abstract: A safety signal jacket includes the garment shaped strap jacket, which can be worn over the existing cloths of a rider of non-enclosed vehicles, means bicycles, roller blades, skate boards, skies, jet skies, water skies, snowmobiles etc., comprises of signal apparatus (27, 34) and horn apparatus (40) which alert and forewarn the other vehicles, other non-enclosed vehicles and pedestrian on the road and its' vicinity. Further, said signal light apparatus (27, 34) electrically communicates with switch panel assemblies (37) and power source in battery assembly, and other among devices through plurality of wires, to activate said signal lights (27, 34) and illuminate and flash in an intermittent manner and activate, illuminate and remain on, creating a visible signal to indicate the turning signal, moving signal slowing signal and stopping signal, as well as the horn assembly (40) for sound modulation for warning signal.

Abstract: The objective of this invention is to protect the information entry such as a PIN from theft by observation of the finger movement based on the conventional fixed arrangement of entry keys. The present invention is an information entry device including: keys for information entry; a circular support base on which the keys are mounted concentrically and arranged circularly in order, the support base being rotatable around the center of the circular arrangement for enabling a user to rotate the entire series of the mounted keys without changing their order around the center of the circular arrangement before or after the information entry; and an information discriminator for identifying the respective information of selected keys. This information entry device prevents a PIN or any other information entry from being stolen by someone who glances at the finger movement, since the entire series of the entry keys are rotated before or after the PIN entry.

Abstract: The present invention relates to a chemical reaction processing apparatus for producing and analyzing a plurality of samples, including a measuring and mixing section for producing the samples in different mixing ratios by mixing raw inorganic materials and for arranging the samples in predetermined quantities on a reaction tray, a heating apparatus section for heat-treating the samples on the reaction tray all at once, an X-ray diffracting apparatus section for sequentially performing the X-ray diffraction measurement on the samples on the reaction tray, and a collating and analyzing apparatus section for analyzing measurement results obtained in the X-ray diffraction apparatus section.

Abstract: In accordance with the present invention, there is provided an air purification device including: a first electrode in the shape of a hollow cylinder having both ends open; a second electrode in the shape of a solid needle having a tip end portion of a predetermined length including a pointed tip; a dielectric member covering the second electrode except the tip end portion; and a power supply for applying a high voltage across the two electrodes in order to create a corona discharge, for generating ozone and ion wind. The dielectric material may be of any type of silicone or plastic (including epoxy) as long as it is inexpensive and easy to mold. The dielectric member is, for example, in the shape of a circular flange, providing ease of maintenance and safety measures as well as permitting effective airflow.

Abstract: The disclosed method and apparatus for crushing material such as ice include a controller to actively control the speed, volume, temperature, and humidity of airflow to improve the crushing efficiency.

Abstract: The present invention relates to a fryer provided with a system that generates a high-density electromagnetic field, preventing deterioration of cooking oil. The fryer comprises: an oil container holding cooking oil; a high-voltage power supply to generate high voltage; and an electrode unit connected to the high-voltage power supply. This electrode unit comprises an electrode made of a screw rod. Because the spiral thread has tips in a shape of acute angle, electric fields tend to concentrate around the acute-angle edges on the entire surface, and thus a high-density electromagnetic field is generated in the oil container.

Abstract: Primarily crushed flaky or platy pieces of ice are supplied from a supply port into a rotary blade casing of a high speed rotary snow producing and throwing apparatus toward a rotor blade in the shaft direction of a rotating shaft by strong discharge pressure of a forced blast, crushed into pieces with smaller and finer particle size through second crushing by the rotor blade rotating at high speed, and sent out from a delivery port nearly in the direction of a tangent of the rotational outer periphery of the rotor blade.
