Title: Radical polymerization inhibitor
Inventor: SATO HIROYUKI
IPC: C07B63/04
Filed: 1999-02-16
Abstract: PROBLEM TO BE SOLVED: To obtain a compound having a radical polymerization inhibiting effect still more excellent than that of phenothiazine by effecting the addition reaction of phenothiazine with a sulfur-containing acidic compound. SOLUTION: This radical polymerization inhibitor is a compound obtained by mixing phenothiazine with a sulfur-containing acidic compound such as sulfuric acid, p-toluenesulfonic acid, sulfur dioxide or sulfuric anhydride in a molar ratio of 1/0.1 to 1/10 in a solvent at ordinary temperature. An example of the method for preparing the same consists of adding sulfuric acid dropwise to a suspension of phenothiazine in toluene, filtering off the formed black precipitate, and drying the precipitate. The inhibitor is useful especially when a (meth) acrylic ester is synthesized by adding about 0.0005-5 wt.% inhibitor to the solvent used and reacting (meth)acrylic acid or (meth)acrylic acid chloride with a hydroxy compound. It is also effective in storing a radically polymerizable monomer or a polymerizable composition for a long term.

Title: Zeolite for cleaning exhaust gas and manufacturing thereof
Inventor: ISHIKAWA MICHIO
IPC: C01B39/06
Filed: 1998-02-19
Abstract: PROBLEM TO BE SOLVED: To make the pore size distribution of zeolite pores best suited for exhaust gas cleaning by providing mesopores and micropores of specific pore sizes. SOLUTION: Zeolite has both mesopores with a pore size of 2-5 nm and micropores with a pore size of at most, 2 nm and these mesopores and micropores adsorb hydrocarbons(HC) contained in an exhaust gas. When both misopores and micropores communicate with each other, the UC is adsorbed by the micropores through the mespores and the UC adsorbed by the micropores are desorbed through the mesopores. In this case, the micropores are developed from the intrapore surface of the mesopores. A capillary condensation occurs in the mesopores and the micropores and the vapor pressure p3 of the micropores with a radius of r3 (r2>r3) which are open in the inner face of the mesopores with a radius of r2 is lower than the vapor pressure p1 of the microporers with the same pore size. Which are open alone (p1>p3).  Consequently, the HC is hardly desorbed compared to the case that the HC is desorbed directly from the micropores. Thus the absorptive performance of the zeolite is enhanced when the temperature is high, and the adsorptive performance of the HC or the like and the high adsorptive performance even at high temperatures are realized.

Title: Semiconductor device
Inventor: NAGANO TAKAHIRO
IPC: H01L29/08
Filed: 1981-03-18
Abstract: PURPOSE:To prevent a switching break-down for GTOSCR by a method wherein a rectangular cathode side emitter layers are provided radially in either face of a circular  semiconductor substrate, an anode side emitter layer is provided in the projecting portion to the back face side, while an auxiliary emitter layer or the insulated substances  are provided in the remainding portion to form an inert condition of the semiconductor, and further the other portions are short- circuited. CONSTITUTION:Since an auxiliary anode side emitter layer 21 is spaced apart from a  cathode side emitter layer 5 not to oppose against it, the carrier injected from the  layer 5 can not reach the front of the layer 21 and the p-n junction provided therein  can not be biased over a voltage stored, the layer 21 does not almost perform the implantation of the carrier into a first base layer 3 and therefore it is equivalent to the  insulated substance. Therefore, the electrically active region is defined to the central  portion along III-III, IV-IV sections and the surrounding portions have the structure the  same as in the regions A, B, and consequently the junction region can be formed uniformly substantially in the longitudinal direction of rectangular unit GTO element. As  a result, the electrical property for the unit GTO element becomes uniform and the  switching break-down would scarcely occur.
