Title: Purification of aromatic polyether
Inventor: KUROKI MASAKATSU
IPC: H01L21/768
Filed: 1998-05-19
Abstract: PROBLEM TO BE SOLVED: To obtain an aromatic polyether having excellent heat resistance and dielectric properties and a high purity by treating an aromatic polyether with an organic acid which leaves no impurities after being dried by heating to remove metallic impurities therefrom. SOLUTION: The aromatic polyether used is not particularly limited so far as it is the one that can attain heat resistance and low permittivity satisfactory for a semiconductor material. It is exemplified by a polymer comprising 2,6- diphenylphenol units. The term 'high purity' herein used means that the concentrations of sodium and copper are 0.08 ppm or below, respectively. The organic acids which leave no impurities after being dried by heating and used for the purification of the polymer are exemplified by formic acid, acetic acid, propionic acid, butyric acid, oxalic acid, malonic acid, and succinic acid, among which acetic acid is particularly desirable. A general method for purifying the polymer consists of refluxing a solution containing the polymer and the acid and removing ions and the acid by washing.  Further, it is also effective that this method is used in conjunction with a treatment with an ion exchange resin or an inorganic ion adsorbent.

Abstract: PURPOSE:To obtain bias raw fabric of any angle with a simple constitution by leaving planar raw fabric at rest on a working table and by bias cutting of its end with a cutter and then by successively jointing the ends of the resultant cut pieces. CONSTITUTION:The end of raw fabric W is obliquely cut at two positions and a cut piece B2 taken along the cut lines is held with the fingers 23, 23 of the second holding means 2 on a working table T; along with this, the end on the first holding means 1 side and the cut end of the raw fabric W to be drawn next are situated so as to enable back overlap.

Title: Defocusing detector of optical disk head
Inventor: SHIKAMA SHINSUKE
IPC: G11B7/09
Filed: 1983-08-24
Abstract: PURPOSE:To adjust easily the position of a photodetector to shorten the adjusting time and to reduce the cost required for adjusting by inclining the directions of two divided straight lines of the photodetector so as to be non-parallel, and executing the distance adjustment between both divided lines only within a surface vertical to an optical axis. CONSTITUTION:The photodetector 15 is formed by inclining the directions of two divided straight lines so as to be non-parallel. The width of the center area I of a position of a reflected light spot to the photodetector 15 when a disk 3 is located on a focusing position is adjusted by moving said width within a surface orthogonal to the optical axis of the photodetector 15 along the divided lines. The width is adjusted so that the quantity of photodetection in the area I coincides with the sum of photodetection in both areas II, III, i.e. the offset of a defocusing detection output from a differential amplifier 12 goes to ''0''. Consequently, the position control of the photodetector 15 can be attained only within the surface orthogonal to the optical axis, so that the adjusting cost can be reduced.

Title: Sand stripper for casting in casting operation
Inventor: BASE MASAYUKI
IPC: B22D39/02
Filed: 1984-07-24
Abstract: PURPOSE:To strip efficiently and concentrically sand from a casting by pressing the casting which is held suspended by a hanger to an inclined oscillation diaphragm and oscillating the casting. CONSTITUTION:The casting 40 is suspended by the hanger and is conveyed along a guide rail 10. The driving of a driving roller device 7 stops and the casting 40 is stopped when the casting arrives alongside the oscillation diaphragm 24 of a sand stripper 13. A cylinder 19 is then driven to extend a driving rod 20 and a turning member 17a turns counterclockwise around a shaft 29. The member stops at the point of the time when the member turns by a prescribed angle, then the casting 40 contacts in the inclined state with the diaphragm 24. When an oscillating motor is driven, the linear oscillating force is generated to oscillate the diaphragm 24. The casting 40 in contact therewith is also oscillated while being subjected to repetitive impact force. The molding sand sticking to the casting 40 is thereby stripped.
