IPC: C08G65/44
Filed: 1997-12-01
Abstract: PROBLEM TO BE SOLVED: To obtain a catalyst which is not inactivated during use in polymerization and can give a polymer within a short time in high yields even when used in a small amount under extensive polymerization conditions by including a copper compound and an amino-containing thioether compound. SOLUTION: The copper compound used is exemplified by cupric chloride and is used in an amount of 0.01-1 mol per 100 mol of the phenolic compound. The thioether compound is represented by the formula (wherein R1 and R2 are each a hydrocarbon group; and R3 and R4 are each H or a hydrocarbon group) and is, for example, 2-methylthioethylamine or 3-methylthiopropylamine. Although not particularly limited, its amount of use is desirably in the range of 1-100 mol per mol of the copper. By adding an amine compound (e.g. dimethylamine) to this catalyst system, its catalytic activity can further improved to reduce the amount of the catalyst necessary for obtaining a polyphenylene ether.

Title: Plane surface polishing method
Inventor: KAGAMI KAZUMI
IPC: B24B37/10
Filed: 1993-12-27
Abstract: PURPOSE:To provide a product having a totally uniform flatness easily by installing a work on a lower surface of a holding plate capable of horizontal rotation, pressing it to an upper surface of a polisher while oscillating it within a horizontal surface for polishing it, and stopping the work at an oscillation end part for a specified time. CONSTITUTION:After a specified work W is installed on a lower surface of a holding plate 3, a polishing plate 2 is rotated, while the holding plate 3 is rotated by a drive device through a plate shaft 4. An oscillation shaft 5 is rotated normally and inversely by an oscillation drive device 9 to oscillate an oscillation arm 6, while the plate shaft 4 is lowered by actuation of a fluid crimp cylinder 7 for pressing the work W on the lower surface of the holding plate 3 onto an upper surface of the polishing plate 2. The work W is thus rotated while it is oscillated along the upper surface of the polishing plate 2 to be polished. When the work W reaches an oscillation end part S, oscillation of the work W is stopped for a specified time, and polishing is applied sufficiently to a work center part, thereby a product having a totally uniform flatness can be provided.

Title: Coding constant envelope modulation system
Inventor: YAMASHITA ATSUSHI
IPC: H04L1/00
Filed: 1989-12-20
Abstract: PURPOSE:To improve the power utilization efficiency by including useful information such as error correction information to a compensation signal in the case of constant envelope processing. CONSTITUTION:An error correction coder 1 generates an error correction code to correct when an error exists in a reception side with respect to an inputted transmission data and outputs DI, DQ are outputted respectively to a transmission filter 2 and a polarity switching section 4. The transmission filter 2 uses the transmission data DI to apply waveform shaping as a transmission signal TI, and an error correction transmission redundancy bit for error correction outputted from the error correction coder 1 is used as a compensation signal DQ to obtain a compensation signal TQ in the case of both the positive and negative polarity. That is, a constant envelope modulation means and an error correction means are combined to use an error correction redundancy bit as a compensation data. Thus, it is not required to send the error correction redundancy bit and the power utilization efficiency is improved.

Title: Magnetic head and its production
Inventor: TSUTAKI SHOJI
IPC: G11B5/187
Filed: 1991-12-13
Abstract: PURPOSE:To decrease the pseudo signals generated from the pseudo gaps by forming a U-shaped groove at a point near the interface between a main core and a subcore. CONSTITUTION:A gap 45 of a magnetic head core 33 is formed by adding the soft metallic magnetic films 43 and 44 like Sendust, etc., to the oxide soft magnetic core half bodies 41 and 42 like ferrite, etc., with the abutting gaps secured among these films and half bodies. At the same time, the pseudo gaps 46 and 47 are produced since the interface between the core half bodies and the magnetic films is unable to keep the complete magnetic continuance. The core 33 undergoes a plane finishing process in order to secure a prescribed gap depth (d) and then a protective material like a resist 24, etc., is provided on the gap 45. Thus a current is impressed to a winding 25 while the breakage of the gap 45 is prevented and the abrasive grains 22 are gathered at both gaps 46 and 47. Thus the smooth U-shaped grooves 26 and 27 are prepared. As a result, the recess sizes can be controlled according to the sizes of both gaps 46 and 47.

Abstract: PURPOSE:To make the capacity changeable continuously and steplessly by providing a rear sub-plate having a bypass hole rotatably between one end plate and a rotor, and connecting both chambers with each other when both surfaces of vanes cover the bypass hole. CONSTITUTION:If a bypass hole 59b of a sub-plate provided between a rear end plate and a rotor 15 is covered by rotation of the rotor 15 by an eccentric shaft 22, compression gas from a chamber 38 is not discharged from a discharge port 40 but bypassed to a chamber 37 instead, and if it gets apart from the bypass hole 59b, compression gas in the chamber 38 is discharged, while the other of the chamber 38 gets into a suction process, making the chamber 37 have the maximum volume. If a vane 18a covers the bypass hole 59, gas in the chamber 37 is bypassed to the chamber 38 without being compressed. The relation between the bypass holes 59a, 59b of the sub-plate and the vanes 18a, 18b is thus change by rotation of the sub-plate by a drive piston receiving the discharge pressure. Continuous stepless capacity changeable operation is thus enabled.
