Title: Production of plzt ferroelectric thin film
Inventor: OKADA MASARU
IPC: C30B29/32
Filed: 1996-06-29
Abstract: PROBLEM TO BE SOLVED: To produce the PLZT ferroelectric thin film at a high deposition rate with good reproducbility by using more liquid materials as organometallic starting materials each contg. any one of constituent metals (i.e., Pb, La, Zr and Ti) of the PLZT thin film at the time of producing a PLZT thin film with an MOCVD(metalorganic chemical vapor deposition) method. SOLUTION: In this production by an MOCVD method using four organometallic starting materials each of which contains any one of Pb, La, Zr and Ti, at least three organometallic materials each being in a liquid state at room temp., are used as the starting materials. For example, a tetraalkyllead such as Pb(C2 H5 )4 or Pb(CH3 )4 , La(C11 H9 O2 )3 or La(i-C3 H7 .C5 H4 )3 , Zr(t-OC4 H9 )4 and Ti(i-OC3 H7 )4 are used as the organolead starting material, organolanthanum starting material, organozirconium starting material and organotitanium starting material respectively. Of these starting materials, only La(C11 H9 O2 )3 is a solid material and all the other materials are liquid materials at room temp. Thus, by using the above four starting mateirals, the objective PLZT thin film can be produced.

Title: Separating device for accompanied particle from flow of molten metal
Inventor: BERUNERU MENKU
IPC: B01D29/00
Filed: 1991-07-04
Abstract: PURPOSE: To make it possible to separate the entrained particles from a molten metal stream by pushing out of the metal stream the entrained particles into a surface region based on changes in velocity and surface tension and then blocking the particles on a mechanical separation surface. CONSTITUTION: The uniform wettability with a slip causes good homogeneity of a particle absorber so that a carrier structure is constituted of welded or braided wire nettings. The filter effect is improved by superpositioning a plurality of wire netting layers in a staggered manner. The strength of the particle absorber is determined by the carrier, i.e., by the wire netting, and the wire netting has a strength sufficient to dry the ceramic layer. As ceramic matrix, Al2 O3 and ZrO2 are mainly used, and AlPO4 and Al(OH)3 are added as the binder. The slip mixed with these constituents is applied to the wire netting and dried particle absorbers are combined to form plural layers.  As a result, the particle absorber has a number of contact surfaces and the entrained particles are separated based on increased surface tension along the contact regions between the molten metal stream and the effective surfaces.

Filed: 1987-07-29
Abstract: PURPOSE:To realize the high-speed working of a data flow processor by performing the convolution processing just with a fact that N pieces of tokens to be processed make a round of an internal ring. CONSTITUTION:A link table 11, an operand fetch table 12, a data memory 13, a function table 14, a buffer queue 15, and a processing unit 16 are successively connected together in a ring form via a pipeline type bus. The tokens are transferred along said internal ring bus synchronously with the pipeline clock of a data flow processor 1. When the convolution is carried out with N pieces of data, it is possible to fetch a coefficient w(i) via the table 14 by means of a group identifier of the group tokens. Thus it is not required to make a token train produced by a token producing part 20 make two rounds of the ring bus for fetching N pieces of data and the coefficient w(i). Thus the convolution processing is performed at high speed.
