Title: Introduction of methylene group to n-phenylcarbamic acid ester
Inventor: FUKUOKA SHINSUKE
IPC: C07C239/00
Filed: 1981-03-16
Abstract: PURPOSE: To obtain methylene-bis-(4-phenylcarbamic acid ester) useful as a raw material of polyurethane, economically in an industrial scale, by the methylene- introducing condensation of N-phenylcarbamic acid ester with a dialkoxymethane in the presence of a specific solid acid catalyst.  
     CONSTITUTION: The objective compound is prepared by condensing the N-phenylcarbamic acid ester of formula (R is alkyl, etc.; R' is H, alkyl, etc. bonded to the o- or m-position of the urethane group; m is 0W4) with the dialkoxymethane of formula CH 2 (OR) 2  at ≤250°C under atmospheric pressure or positive pressure, in the presence of a solid acid catalyst obtained by the intercalation of a Lewis acid (e.g. CuCl 2 ) in graphite.  
     EFFECT: Since the catalyst is solid acid, various side reactions such as deactivation of the catalyst, partial dissolution of the catalyst components, etc. can be suppressed. The corrosion of the apparatus is reduced compared with the case using liquid acid catalyst. The operation is easy, the catalyst can be reused, and the discharge of the aqueous solution of the waste acid can be prevented.

Title: Semiconductor storage device and manufacture thereof
Inventor: TSUKAMOTO KATSUHIRO
IPC: H01L29/78
Filed: 1987-02-19
Abstract: PURPOSE:To decrease the carrier collecting efficiency of a region having a different conductivity type from that of a substrate and to substantially decrease soft errors, by providing a high-concentration buried layer having the same conductivity type as that of the substrate such that it is located shallowly under a charge collecting capacitor and deep under a read/write transistor. CONSTITUTION:A high-concentration buried layer 101 having the same conductivity type as that of a semiconductor substrate 1 is formed within the semiconductor substrate 1, such that the buried layer 101 is located shallowly under a charge storing capacitor region and deep under a read/write transistor region. This high-concentration buried layer 101 not only prevents funneling action by inhibiting extension of a depletion layer at N<+>-P junction but also serves as a barrier against carriers diffused from inside of the semiconductor substrate 1 towards a region having a different conductivity type to that of the capacitor and substantially decreases the carrier collecting efficiency thereof. Further, since the layer 101 is buried shallowly under the charge storing capacitor and deep under the read/write transistor, it is prevented from adversely affecting operation of the transistor.

CONSTITUTION: In a method for controlling output of access packet, output information indicating the transmitting output (Tpo(BTS)) on a broadcasting channel(BCCH) is included in the channel (BCCH) at the level of a transmitting- receiving base station (BTS). At the level of a mobile station (MS), the output received on the channel is measured and the estimated value of the propagation loss to the base station (BTS) from the mobile station (MS) is deduced by comparing the measured value (RP(MS)) of the output with an transmitting output obtained from transmitting output information contained in the broadcasting channel(BCCH) and the optimum transmitting output of an access packet (PA) is decided from the estimated propagation loss and the parameter of a system. This method can be utilized for the radiotelephony, particularly, GSM system and TFTRA system.
