Title: Spheroidal cement and production thereof
Inventor: SHIODA YUJI
IPC: C04B7/19
Filed: 1989-12-28
Abstract: PURPOSE:To enhance fluidity by dispersing both cement clinker fine particles and an organic or inorganic binder into a solvent except water and spheroidally granulating them and thereafter adding gypsum powder to the granulated cement clinker. CONSTITUTION:100 pts.wt. (hereinafter shown in part) fine cement clinker particle regulated to about <=10mum mean particle diameter is dispersed into the prescribed amount of a solvent such as ethanol except water. Then an organic binder such as PS or an inorganic binder such as ethyl silicate is added at about 0.1-5 parts and dispersed. The solvent in which cement clinker and the binder are dispersed is supplied to a granulator and these are granulated to a spheroidal shape having about 20-30mum mean particle diameter. Thereafter gypsum powder having about 20-30mum mean particle diameter is added at about 0.5-5 parts to 100 parts of the granulated cement clinker. This mixture is regulated to the required hydraulic speed and spheroidal cement good in fluidity and packing property is obtained. Further gypsum powder regulated to <=10mum particle diameter is dispersed into the solvent together with cement clinker and then these may be granulated by the binder.

Abstract: PROBLEM TO BE SOLVED: To manufacture a MOS transistor with a desired breakdown strength with a high degree of design and the minimum number of processes in a semiconductor device, where high-voltage and low-voltage NMOS and PMOS transistors are mixed on a same semiconductor substrate. SOLUTION: N-type high-voltage wells 105A-105D are formed on all MOS transistor formation regions of a P-type semiconductor substrate 101, an element separation region is formed, a P-type impurity region that becomes a channel formation region 110A and an expanded drain region 110B of a high-voltage MOS transistor is formed, and further low-voltage wells 110C and 110D of a low-voltage MOS transistor are formed. After that, a MOS transistor is constructed at each well. By adding a slight process to the manufacturing process of a low-voltage MOS transistor, this type of semiconductor device can be manufactured. Also, a dimension accuracy can be improved since the above P-type impurity region is formed with the element separation layer as a mark, and a MOS transistor with a desired withstand voltage can be obtained since no succeeding high-temperature heat treatment exists.
