A method for producing an electrostatic chuck 10 includes the steps of (a) pouring a ceramic slurry containing a ceramic powder, a solvent, a dispersant, and a gelling agent into a first molding die 31 in which an electrostatic electrode precursor 24 is removably attached to an inner surface of the first molding die 31, gelatinizing the ceramic slurry by causing a chemical reaction of the gelling agent, and then removing the first molding die 31 to prepare an embedded-electrode-containing ceramic molded body 41X in which the electrostatic electrode precursor 24 is embedded in a first ceramic molded body 41; (b) preparing a second ceramic molded body 42; and (c) preparing a stacked calcined body 50 using the embedded-electrode-containing ceramic molded body 41X and the second ceramic molded body 42, and conducting hot-press firing of the stacked calcined body 50.

An impact tool includes a motor, a hammer casing with an opened rear end and a disk-shaped member coupled to the hammer casing to close the opened rear end and to rotatably support a spindle. A first engagement member is formed on an outer face of the disk-shaped member. A second engagement member is formed on an inner face of the recess and engaging with the first engagement member to restrict a movement of the hammer casing in a second direction parallel to a rotation axis of the spindle. A third engagement member is formed on an outer face of the hammer casing. A fourth engagement member is formed on an inner face of the housing body and engaging with the third engagement member so as to restrict a movement of the hammer casing in the first direction.

An electrical power tool may include a base capable of contacting the work-piece, a tool main body detachably attached to the base, and an elevating mechanism that is capable of changing a relative position of the tool main body to the base. The elevating mechanism includes a male elevating member that is releasably integrated with the tool main body, a female elevating member that is attached to the base and is capable of relatively raising and lowering the male elevating member, and an integrating mechanism that is capable of releasably integrating the male elevating member with the tool main body. The tool main body is capable of being removed from the base while the male elevating member is left in the base when the male elevating member is released from the tool main body by operating the integrating mechanism.

A method for controlling the shrinkage of ceramic formed bodies is provided, including performing a preliminary test to determine an average shrinkage of ceramic formed bodies made from test lots of a ceramic powder, and determining a linear correlation between the average shrinkage and measured amounts of the ground test lots removed from a ball mill during a specific milling time interval. A batch of the ceramic powder is then ground, an amount of the ground ceramic powder removed from the ball mill during the specific time interval is measured, and the linear correlation is used to estimate the shrinkage of a ceramic body made therefrom. The difference between a target shrinkage and the estimated shrinkage is determined, and one or more of the processing conditions used to form the ceramic body are changed to offset the difference.

The present invention provides a method for controlling the shrinkage of formed ceramic bodies, by which it is possible to suppress fluctuation of the shrinkage of formed ceramic bodies and to cause the shrinkage to approximate the target rate. The method comprises controlling the shrinkage of formed ceramic bodies in manufacturing ceramic products by a predetermined manufacturing process from ceramic powder ground by a dry-type ball mill. Such control can be achieved by determining a correlation between the change in the amount of the ground ceramic powder taken out from the dry-type ball mill with elapse time and the shrinkage during firing of the formed ceramic body, and thereafter adjusting the manufacturing conditions based on the previously-determined conditions for the above-mentioned manufacturing process and the correlation with respect to the shrinkage obtained.

Two grooves are provided on a rear face of the remote control transmission apparatus and a plurality of electrodes are arranged in the grooves in substantially the same direction as an extension direction thereof. The plurality of the electrodes are connected to a conversion device. The conversion device measures an impedance between each of the electrodes and the finger placed in the groove, codes that impedance distribution pattern and transmits it to a recognition device. The recognition device determines whether or not he is a particular registered person by verifying with a preliminarily stored registration pattern and controls availability of a pay channel according to the determination result.

The invention provides a ceramic green sheet having plasticity, punching property, and sinterability of satisfactory levels as well as a low percent (heat) shrinkage. In the production of a ceramic slurry serving as a raw material of the sheet, ingredients thereof are mixed under such conditions that the functional group ratio (polyol to isocyanate) is 1.5/11.5 to 11.5/11.5; the urethane resin formed from isocyanate and polyol has a repeating-unit-based molecular weight of 290 to 988; and the ratio by weight of the urethane resin to a ceramic powder falls within a range of 4.5 to 10 parts by weight of the urethane resin with respect to 100 parts by weight of the ceramic powder. A ceramic green sheet having, in well balance, all of the properties (i.e., plasticity, punching property, sinterability, and (heat) shrinkage) required for facilitating subsequent processes such as mechanical working and firing can be provided.
