Title: Method for reducing volume of water contained in piezoelectric gapo4 crystal element, apparatus for performing this method, and crystal element manufacturedby this method
Inventor: GIYUNTA ENGERU
IPC: H01L41/39
Filed: 1988-11-11
Abstract: PURPOSE: To effectively reduce the water content of piezoelectric GaPO 4  crystal elements by cutting off the piezoelectric GaPO 4  crystal element only from the single growth region of a GaPO 4  crystal blank with deviation from the region boundaries, then immersing the cut crystals into a soln. mixture of a Karl Fisher's soln. and methanol anhydride.  
     CONSTITUTION: The GaPO 4  crystal element 3 is cut off from the single growth region (e.g.; growth region Z) of the GaPO 4  crystal blank 1 with deviation from the region boundaries. The cut off piezoelectric GaPO 4  crystal element 3 is then immersed into the soln. mixture composed of a volumetric ratio of 1:1 of the Karl Fisher's soln. and the methanol anhydride and is heated preferably in the state of expelling moisture in a closed system, by which the water content in the GaPO 4  crystal element is reduced. The resulted piezoelectric GaPO 4  crystal element is improved in the physical parameter depending upon the water content, for example, resonance class and is adequately used for resonators, etc.

Inventor: ASOU TOMOMICHI
IPC: F23D14/02
Filed: 1997-10-21
Abstract: PROBLEM TO BE SOLVED: To prevent odor upon firing in a thin and thick combustion system. SOLUTION: A thin and thick burner part 5 comprises a plurality of thick burners 2 and a plurality of thin burners 4 both alternately disposed, and fuel is supplied from a thick nozzle 15 and a thin nozzle 19. Since the small thick nozzle has a small thick-nozzle diameter at a position corresponding to an ignition plug, the amount of injected fuel is reduced, and a pre-mixing air ratio of the thick burner 2 is relatively increased and approaches a theoretical air ratio. Thus, firing at the ignition plug is facilitated, and hence odor upon firing is reduced.

IPC: G06F21/62
Filed: 1990-10-29
Abstract: PURPOSE:To protect information so that the contents of an external storage device can not be decoded carelessly by comparing data protection information in the storage device with a pass word (key data) from a system, and canceling protection by the coincidence of the pass word. CONSTITUTION:A system interface control circuit 3 in the external storage device 2 immediately after the start of the system is made to accept only a pass word (key word) command. On the reception of the pass word command from a host system 1, it is checked whether the sent pass word coincides with the contents of a memory 5 for the pass word, that is, the pass word for protecting the data or not.
