Title: Electrostatic chuck and evaluation method thereof
Inventor: WATANABE SHOJIRO
IPC: H01L21/683
Filed: 1998-05-06
Abstract: PROBLEM TO BE SOLVED: To prolong the service life of an electrostatic chuck under a high- temperature service condition by making the chuck of a sintered aluminum nitride material containing an AlON phase and boron nitride. SOLUTION: An AlON phase and boron nitride are mixed in a sintered aluminum nitride material used for making an electrostatic chuck. The AlON phase improves the electrostatic attracting force of the chuck for wafer. In addition, boron nitride reduces the cracking of the chuck and the separation of an electrode layer and an exothermic resistor layer from each other at their boundary, even if the chuck is repeatedly used under a high-temperature conditions of 300 deg.C. The sintered aluminum nitride material is manufactured by adding alumina (Al2 O3 ) powder which is added to produce the AlON phase and boron nitride powder to aluminum nitride powder, and after molding, the molded product is baked at a high temperature of about 1,800 deg.C or higher under a non-oxidative atmosphere of nitride, argon, etc.

Title: Ignition device for internal combustion engine
Inventor: TAHIRA MUNEAKI
IPC: H01F38/12
Filed: 1994-06-06
Abstract: PURPOSE:To prolong the life of an ignition device, even if a switching semiconductor device separates and improve the reliability by packaging the semiconductor device having a power region of a main heat source located at a central part of this device and a protective circuit region located round this power region. CONSTITUTION:A semiconductor device 14 is composed of a power region 20 of a main heat source located at a central part and a protective circuit region 21 located round the power region 20. The power region 20 on the main power source corresponds to a transistor and the circuit region 21 corresponds to a Zener diode. When a semiconductor device having the above structure is mounted on a substrate, the thermal flux generated at the power region flows in a thermal conduction- and heat transfer-increasing direction, i.e., toward the substrate on which the semiconductor device is mounted. Hence, the thermal flux density is unchanged, so far as the separation of this device does not progress just beneath the power region, through progressing more than round the power region. Thus, the Joule heat generated by the semiconductor device can be stably dissipated therefrom.

Title: Method and apparatus for separating bacteria from bacteria-containing liquid specimen
Inventor: MATSUKUSU SUPINERU
IPC: B04B11/06
Filed: 1983-07-08
Abstract: In a method of separating bacteria from a bacteria containing liquid sample by means of a dish-like centrifuge container (21) having an upper opening (25) defined by a radially inwardly extending rim portion (24), the following sequential steps are carried out. The centrifuge container is rotated at a high rotational speed. A volume of a high density component of a density higher than the density of the bacteria is introduced into the centrifuge container, whereupon a volume of a low density component having a density lower than the density of the bacteria is introduced into the container so that a two component gradient separation layer (60) comprising a high density layer (61) and a low density layer (62) is formed within the centrifuge container (21). The liquid sample is introduced through a supply tube (32) into the center of the centrifuge container, and owing to the centrifugal force generated by the rotation of the centrifuge container, the liquid is thrown outwardly from the center of the centrifuge container. The bacteria are forced into the low density component layer (62) and deposited in the interface (63) between the two layers (61) and (62), while the liquid sample is discharged (66) from the upper opening of the centrifuge container through a notch (26). A flushing agent is introduced into the centrifuge container and discharged from the upper opening thereof together with any material adhering at the peripheral surface of the gradient separation layer (60). The centrifuge container (21) is decelerated to a low rotational speed, whereafter a suction pipette (40) is activated and moved from a first position having its tip remote from the inner surface of the peripheral wall of the centrifuge container (21) to a second position having its tip arranged adjacent to said inner surface, while a volume of a transfer liquid is introduced into the centrifuge container so that liquid substance included in the centrifuge container is sucked off therefrom through the pipette tube (41) of the suction pipette (40).
