Abstract: The end of a communication period can be detected reliably and efficiently by a control unit and validity/invalidity of search rules in a search table can be effectively managed. A timer is provided so as to correspond to each entry area of the search table. Then, under control of a timer managing unit, the timer starts a counting operation whenever information is written in a validity management table or a packet in which a communication parameter matches a packet search condition corresponding to information on the validity management table that is set as valid is received. In addition, when a counting time of the timer exceeds a preset time-out time, information indicating the time-out is stored in a time-out management table.

Abstract: An image filing method, in which a plurality of images are registered one by one, and the registered images are retrieved by adding a retrieval condition so as to be simple and not require time and labor at the registration and retrieval times. A plurality of symbols for featuring objects in the images are set in advance, and the images are registered corresponding to the selected symbols. At the image retrieval time, the symbols are selected, and the images corresponding to the selected symbols are read out.

Abstract: A color image reading apparatus includes a multi-chip image sensor having a plurality of image sensor units adapted to read a test chart comprising a color slip having a plurality of colors. A processing circuit is provided for automatically calculating color correcting coefficients, respectively, for the plurality of image sensors and storing them in memory. This will reduce problems of color reproducibility among image sensors and among image reading apparatus.

Abstract: An electric motor assembly for driving an air blower is disclosed. The assembly comprises a casing of metal, the casing having opposed open ends closed by respective covers of metal; a rotation shaft rotatably disposed in the casing, the rotation shaft having one end exposed to the outside through an opening formed in one of the covers, the one end being adapted to connect to a fan of the air blower; a plurality of magnets installed in the casing and circumferentially surrounding the rotation axis; an armature mounted to the rotation shaft to rotate therewith; a commutator mounted to the rotation shaft and electrically connected with the armature; brushes operatively contacting with the commutator and supported by the casing; and an electric power feeding device for feeding the brushes with an electric power. A pulse width modulating device is further employed which is electrically connected with the power feeding device for modulating the electric power by means of a pulse width modulation method.

Abstract: In a forming method and a mold wherein a slip is cast into the mold and wherein the mold is removed after hardening of the slip, the mold is patterned by the use of a water-soluble binder. The mold absorbs a water content in the slip to soften and to become easy of removal, while the slip has the water content absorbed to harden promptly. Therefore, the forming method and the mold are especially suited to produce a cast article of complicated shape.

Abstract: A heat storage material is produced by adding water and slight amounts of substances for agglomerating residuals to industrial grade calcium chloride.

Abstract: A heat-storing vessel filled with a heat-storing material of latent heat type is provided with a fluid flow passage in thermal contact with the heat-storing material for passing a fluid for storing and releasing heat. By passing a hot fluid through the fluid flow passage, the heat-storing material in the heat-storing vessel is melted to store heat. By passing a cold fluid through the fluid flow passage, the heat-storing material in the heat-storing vessel is solidified to release heat. The heat-storing material contains a gelling agent to suppress a phase separation phenomenon. A low temperature part is provided at a part of the heat-storing vessel and the heat-storing material containing the gelling agent is retained in a solid state at the low temperature part to prevent supercooling of the heat-storing material.

Abstract: A heat storage material to be used for air cooling systems is provided. This heat storage material comprises acetic acid or a mixture of acetic acid and one or more acetates and is further added with at least one anhydrous halide as nucleating agent to prevent supercooling.
