Abstract: PURPOSE:To produce the title fine powder contg. scarcely agglomerated particles by heating crystalline hydrous zirconyl chloride or a solid mixture consisting primarily thereof at a specified temp. in a closed vessel, holding the product at the temp., then heating, dehydrating, caking, drying or calcining after releasing the product from tightly closed condition.

The material is heated at 150-300 deg.C in a closed vessel, and held for a sufficient time necessary for generating crystallized ZrO2. In this stage, said zirconyl chloride is hydrolyzed slowly by its own water of crystallization to form white paste mixture. Then, the vessel is released from tightly closed condition, and the product is dehydrated by heating as it is, and dried or calcined. By this method, relatively coarse fine particles having >=0.3mu particle size of relatively uniform particle size distribution are obtd.

Title: Fluid transfer control method
Inventor: YAMADA SHIGEO
IPC: G05D16/00
Filed: 1978-09-04
Abstract: PURPOSE: To perform terminal pressure constant control and exhaust pressure constant control  for normalcy and instantaneous stop respectively by restoring the exhaust pressure to a state  before instantaneous stop rapidly after restoration of instantaneous stop to eliminate disturbance  of the terminal pressure.  
     CONSTITUTION: At a normal time, the newest exhaust pressur detected by exhaust pressure  detector 23 is stored in exhaust pressure storage unit 19. Next, at instantaneous stop, when  instantaneous stop is detected by instantaneous stop detector 24, the exhaust pressure at the  instantaneous stop detection time is stored and held in storage unit 19. Under this state, speed  arranging control unit 17 compares the exhaust pressure at the instantaneous stop occurrence  time with the exhaust pressure after the instantaneous stop occurrence time and controls a pump  according to this comparison result. This control switches the exhaust pressure before instantaneous stop to the set value of the terminal pressure which is the set value of control before instantaneous stop, and similarly, this control switches controlling feedback signal to the output of  detector 23 from the output of terminal pressure detector 15. Thus, exhaust pressure is controlled  to obtain the exhaust pressure before instantaneous pressure after instantaneous stop occurs.  When the exhaust pressure becomes the state before instantaneous stop, switches 20 to 22 are  switced to states before instantaneous stop again to perform the terminal pressure control before  instantaneous stop.

Abstract: PURPOSE:To prevent field inversion effectively without thickening a field oxide film with the fining of an element and increasing the concentration of a diffusion layer for obviating inversion by forming the high section of the density of trapping centers only in the thickness direction of a field insulating film just under an electrode wiring. CONSTITUTION:A gate electrode wiring 15 is extended at the central section of an element region 10 and onto a field insulating film 12 in the periphery of the region 10, and one part in the thickness direction of a field insulating film 21 under the gate electrode wiring 15 includes the high section of the densi ty of trapping centers in the field insulating film 21. Such a field insulating film 21 is formed only just under the gate electrode wiring 15 and is not shaped to other sections. Since the trapping center traps electrons and prevents field inversion, the trapping center functions in the same manner as the concentration of an inversion preventive layer 14 is further increased or the thickness of the field insulating film 21 is further thickened.
