Abstract: PURPOSE: To inexpensively obtain high quality goethite without corroding equipment by aging an alkaline suspension prepared by mixing an aqueous soln. contg.  Fe 2+  as a principal component with an oxidizing agent for oxidizing Fe 2+  to Fe 3+   and alkali and by heat-treating the aged suspension.  
     CONSTITUTION: To an aqueous soln. contg. ferrous ion of FeSO 4  or the like as a principal component is gradually added an oxidizing agent such as H 2 O 2  or NaClO 3  for oxidizing ferrous ion to ferric ion, and a soln. of NaOH or other alkali is added with stirring in a slight excess such as about 1W10% excess over the amount required for neutralization. The resulting suspension is held at 20W40, preferably ordinary temp. for 3W20hr while continuing gentle stirring. The suspension thus aged is then heated to a temp. from 70°C to the boiling state and maintained for 5W10hr. It turns yellow, and goethite synthesis is completed.

Title: Data memory method
Inventor: NISHINO YASUKAZU
IPC: G06T3/00
Filed: 1983-07-12
Abstract: PURPOSE:To facilitate easy address control of each memory in the reduction and rotary read modes by using (n) bits as common bits and the remaining (m) bits as those which decide the positions of data respectively among address inputs to be fed to a memory. CONSTITUTION:Data are divided into blocks every (NXM) bits, where N and M equal to >=2 integers. Then (n) bits of address inputs to be fed to a memory circuit 11 are used as those which define blocks. At the same time, the remaining (m) bits are used as those which define the data positions within those blocks. In a write mode of data the input data are converted into parallel data for each 4 bits by an S/P shift register 8 and then written to addresses corresponding to values n, m1-m4 supplied from address conversion circuits 5 and 6 by the circuit 11. In this case, the value of (n) of each memory is used in common within a block, and the value of (m) is used to define an address when the varied data is written to a memory. As a result, the address control is facilitated when data are read out with reduction and revolution respectively.

Title: Sintered contact material for electric power low voltage open-close instrument and manufacture
Inventor: ROTHKEGEL BERNHARD
IPC: H01H1/023
Filed: 1985-06-11
Abstract: Contact materials based on AgSnO2 and having Bi2O3 and CuO as further metal oxide additives were previously disclosed. In these materials the total content of all metal oxides was supposed to be between 10 and 25% by volume with the SnO2 share equal to or greater than 70% by volume of the total amount of oxide. According to this invention the quantity of SnO2 is kept smaller than 70% by volume; specifically at about 65%, but in any case equal to or greater than 50%. The SnO2 weight content is to be in the 4% to 8% range and the weight percentage ratio of SnO2 to CuO is to be between 8:1 and 12:1. In the associated production process, either Bi2O3 powder is purposely admixed to an internally oxidized alloy powder (IOAP) in an additional operation, a grain restructuring with locally different Bi2O3 concentrations occurring in the structure after sintering and compacting. Alternatively, higher bismuth percentages in the alloy powder can be worked with directly, which is again internally oxidized to an IOAP. From these starting materials two-layer sintered contact elements with a solderable silver layer can be efficiently produced.

IPC: H02P27/04
Filed: 1989-05-19
Abstract: PURPOSE:To smoothly switch positive and negative converters by transmitting an externally-set finite value at the time of no-load operation of an AC motor for a reactive current setter to be driven by a cycloconverter. CONSTITUTION:A gate-switching apparatus 13 performs switching a gate pulse by using as parameters three-phase AC set values Iu*, Iv*, Iw* obtained by passing the output of a (magnetic flux axis coordinate system)/(rotor axis coordi nate system) converter 31B through a two-phase/three-phase converter 6B. In this case, a reactive current set value i*d<e>a is given by a reactive current setter in the manner of taking a finite value at the time of no-load operation of an AC motor 33. Therefore, said three-phase AC set values Iu*, Iv*, Iw* are prevented from all becoming zero. Moreover, it is substantially at the time of no load that said reactive current set value i*d<e>a is a finite value.
