Title: Production of arylene thioether-based oligomer and copolymer
Inventor: SATO HIROYUKI
IPC: C08G75/0286
Filed: 1991-04-09
Abstract: PURPOSE:To obtain the subject oligomer, excellent in softness, solubility, mechanical characteristics and processability and useful for injection molded products, etc., by forming a specific oligomer in a hydrous polar organic solvent and then reacting a specific carboxylating agent therewith. CONSTITUTION:An alkali metallic sulfide such as lithium sulfide is reacted with a polyarylene thioether containing recurring units expressed by formula I (Ar is arylene) in a hydrous polar organic solvent such as N-methylpyrrolidone and depolymerization is carried out to form an oligomer having an alkali thiolate group. A carboxylating agent, e.g. p-chlorobenzoic acid expressed by formula II (X is halogen; R1 is H, 1-4C alkyl, aryl or alkali metal; Ar' is arylene) is further reacted with the resultant oligomer to afford the objective oligomer. Furthermore, the aforementioned oligomer alone or a mixture of >=50wt.% above-mentioned oligomer with <50wt.% other carboxylic acid compounds is reacted with an alkyl diol such as ethylene glycol to afford a copolymer.

Title: High-purity silicon carbide sintered material and production thereof
Inventor: KIJIMA KAZUMICHI
IPC: C04B35/626
Filed: 1990-04-19
Abstract: PURPOSE:To obtain high-density sintered material of silicon carbide, containing a sintering auxiliary by introducing a raw material gas comprising a silane compound, etc., into plasma in a nonoxidizing atmosphere to synthesize fine powder of silicon carbide and sintering the fine powder. CONSTITUTION:A raw material gas comprising a silane compound or a silicon halide and a hydrocarbon is introduced into plasma in a nonoxidizing atmosphere. Then the raw material gas is subjected to gas-phase reaction while controlling the reaction system in a range of <1atm. to 0.1Torr. Fine powder of silicon carbide thus synthesized, having <=0.1mum average particle diameter is heated and sintered to give the objective sintered composition. The reason why high-density sintered material of silicon carbide is obtained by the above- mentioned method is considered that the fine powder of silicon carbide used has <=0.1mum average particle diameter and superfine and, because of the clean surface of the fine powder, the fine powder has high sintering activity.

Title: Am wave detecting circuit
Inventor: OOSHITA HIDEO
IPC: H03D1/06
Filed: 1980-08-01
Abstract: PURPOSE:To ensure a good linear wave detection without any distortion of detection and the dependence on the temperature and regardless of the level of a high frequency signal input or the degree of modulation, by previously applying a certain high frequency bias to the high frequency input and then an AM wave detector. CONSTITUTION:A high frequency input signal received an amplitude modulation by a low frequency signal is supplied to an adder circuit 3 through an input terminal 1. While a high frequency bias is applied to the circuit 3 from a high frequency bias oscillating circuit 2, and an addition signal obtained by superposing a high frequency signal input on the high frequency bias is delivered from the circuit 3 to be applied to an AM wave detector 4. With application of the high frequency bias to the high frequency signal input, the virtural degree of modulation is reduced for the high frequency signal input. Then the level of the envelope curve is raised to cope with the linear region of the wave detecting properties of a diode within the detector 4. In such way, a wave detection output free from any distortion of detection can be obtained through an output terminal 5.
