Title: Production of allyl chloride
Inventor: MIYAKE TAKANORI
IPC: C07C17/156
Filed: 1991-09-04
Abstract: PURPOSE:To obtain in high selectivity the title compound useful as a raw material for epichlorohydrin or an intermediate for synthesizing various organic compounds by oxychlorination of propylene in the presence of a tellurium-contg. alloy catalyst. CONSTITUTION:Reaction is made at 100-350 deg.C between propylene, hydrogen chloride and oxygen pref. in a gaseous phase using a catalyst containing an allay made up of tellurium and group VIII (e.g. Fe), group Va (e.g. Sb) and/or group Ib (e.g. Cu) metal(s) carried on a carrier, thus affording the objective allyl chloride. The allay may be incorporated with an alkali metal compound. Use of the above catalyst will enable the oxychlorination at lower temperatures and result in no accumulation of carbon scale in the reaction system. For the oxychlorination, hydrogen chloride can be used rather than chlorine.

IPC: H01L27/04
Filed: 1986-10-22
Abstract: PURPOSE:To contrive improvement both in percentage of fluctuations in output voltage against the change of input voltage and the degree of input stability by a method wherein the resistor, connected between the drain electrode of the MOS transistor to be used for output control and a power source, is formed on the substrate of the electric potential same as the connected power source or on a well region. CONSTITUTION:Input voltage is applied between a positive power source terminal (VIN terminal) and a negative power source terminal (GND terminal) 3, and when load is connected between an output voltage terminal (VOUT terminal) 2 and the GND terminal 3, a load current is made to flow. The drop of output voltage when the load current increases in the amount of  Io is detected by the voltage at the detection point A of the variation in output voltage which is formed by dividing the output voltage by the resistors 7 and 8 connected between both terminals, and the detected value is compared with the reference voltage using a comparator 5. The obtained value of deviation is amplified, and when the output voltage is controlled in the direction of rising by the MOS transistor 6 to be used for the output control located between the VIN terminal 1 and the VOUT terminal 2, the fluctuations of output voltage can be suppressed. To be more precise, the fluctuations of the output voltage is detected by the voltage at the detection point A of the fluctuations of the output voltage which is resistance-split by the resistors 7 and 8, and the stabilized power source is obtained by performing a feedback on the MOS transistor 6 to be used for output control.

Abstract: PURPOSE:To obtain a reduction print result with fidelity to a reduction ratio by providing a means to generate and print a reduction dot image by reducing the patterns of a character and a graphic, etc., fitting in the reduction ratios of character pitch and row pitch when reduction printing is performed. CONSTITUTION:Firstly, a plotting area is initialized.
