Title: Ashing process using vertical batch type asher
Inventor: EGASHIRA KYOKO
IPC: H01L21/027
Filed: 1990-03-20
Abstract: PURPOSE:To avoid the deterioration in the distribution of ashing rate in the vertical direction by a method wherein, after finishing one time batch process, He gas is led in an ashing chamber to forcibly cool down the temperature inside the chamber and then the starting temperature for the next process is reset to the initiallized temperature. CONSTITUTION:He gas is led from a feeding port 1a while wafers are being taken out and then the temperature in the chamber 1 is reset to the initiallized temperature. At this time, the He gas lighter than atmospheric air will suffice to circulate even in the upper part of the chamber 1 to be cooled down. Then the temperature in the chamber 1 raised up by the ashing reaction heat is rapidly cooled down to reset the starting temperature for the next batch process to the initiallized temperature. Accordingly, the starting temperature at every batch process can be reset to the initiallized temperature. Through these procedures, the deterioration in the distribution of ashing rate when the repeated batch process is continuously performed can be avoided.

IPC: G06F17/30
Filed: 1992-02-21
Abstract: PURPOSE:To decrease the number of coding steps by requiring only one declaration for a multiple-index file even when the multiple-index file is accessed with several keys. CONSTITUTION:This system consists of a key data transfer means 20, a special word 1 having said means 20, a key type area 1a, a key position area 1b, and a key length area 1c.

Abstract: PURPOSE:To enable to precisely provide the clearance between a water and a mask by a method wherein the water placing section is supported by a supporting member consisting of an electrostrictive element, which will be expanded or contracted according to the voltage applied. CONSTITUTION:When a DC high voltage is applied to electrostrictive element of the supporting member 2 from a driving source 10 in the state wherein the wafer 15 is separated from the mask 19, the supporting member 2 is extended in proportion to a voltage value. When the voltage value is increased, the supporting member 2 is extended and a protrusion 16 on the wafer placing section 11 comes in contact with the conductive layer of the mask 19. Then, this contact is detected by a contact detecting device 24 and, at the same time, the detection signal is inputted to a driving source 10 and the voltage to be outputted to the electrostrictive element from the driving source 10 is adjusted. This voltage is outputted with a voltage value with which the supporting member 2 can be contracted to the prescribed degree of extent. Accordingly, as the protrusion 16 is separated from the conductive layer of the mask 19, the upper surface of the wafer 15 is maintained to have the prescribed highly precise opposing clearance to the conductive layer of the mask 19.

Filed: 1994-04-12
Abstract: PURPOSE: To simplify manufacture and assembly of a PMDC motor by employing a spacer means for extending an insert in the longitudinal direction between two free edges of a magnet means while traversing the symmetric plane of the motor. CONSTITUTION: After magnets 4 and 5 are arranged in a casing 1 by means of an insert 9 and an additional resilient spacer in the form of a U-shaped spring 10, a PMDC motor is magnetized through charging operation where the motor is subjected to a strong field in the direction vertical to a symmetric plane 3 along an axis passing through the longitudinal shaft 2 of the motor. The insert 9 made of soft steel serves as a magnetic shunt for concentrating the field to the side of same casing 1 and the field axis is displaced from the longitudinal shaft 2 toward the insert 9 and located in a second plane 8 vertical to the plane 3. When an armature 30 is fixed into the casing 1, it is pushed magnetically toward the insert 9 and thereby manufacture and assembly can be simplified.

Title: RAT IgE MEASURING KIT USING ANTI-RAT IgE ANTIBODY AND MEASURING METHOD
Inventor: HONJO TSUTOMU
IPC: G01N33/53
Filed: 1999-03-18
Abstract: PROBLEM TO BE SOLVED: To measure rat IgE in an objective sample by using an antibody (a combination of a polyclonal antibody and a monoclonal antibody) recognizing at least a part of the rat IgE. SOLUTION: Any antibody recognizing rat IgE as an antigen can be used. Therefore, either of a polyclonal antibody and a monoclonal antibody may be used as an antibody. When a polyclonal antibody is used as a solid phase antibody, a polyclonal antibody specifically refined by means of a column with an immobilized purified rat IgE is preferable for suppressing a nonspecific action of the antibody. For providing a high measurement sensitiveness, an antibody F(aa')2 is used as a labeled antibody desirably. For example, in measurement performing a two-step antigen-antibody reaction such as a solid phase sandwich method, as a primary antibody used for coating a carrier, a polyclonal antibody or a monoclonal antibody is used, while two or more kinds of antibodies are used as labeled secondary antibodies.
