Abstract: PURPOSE:To obtain the subject high-strength cement composition by classifying portland cement into a fine powder and a crude powder respectively having its specified maximum particle size, spraying water to the above-mentioned fine powder to suitably partially hydrate and subsequently mixing the resultant hydrated fine powder with the above-mentioned crude powder. CONSTITUTION:Portland cement is classified into a fine powder and a crude powder using a conventional classifier so that the maximum particle size of the above-mentioned fine powder may be within a range of 5-15mum. About 5-50wt.% of powder having a particle size of <= the above-mentioned maximum particle size is preferably classified into the above-mentioned fine powder. Water is sprayed to the above-mentioned fine powder to hydrate and its ignition loss is increased by 0.1-1.5wt.%. The above-mentioned water spray is carried out by blowing steam on the fine powder with stirring at a high speed or by spraying water so as to make to attach water to the fine powder uniformly. The resultant fine powder having a reduced hydration activity due to the above- mentioned treatment is mixed with the above-mentioned crude powder again. An objective high-strength cement composition showing a high strength especially at an initial age can be obtained thereby.

Title: Gate drive circuit of voltage driven type semi-conductor element
Inventor: KAWAI TAKAFUMI
IPC: H02M1/08
Filed: 1990-05-24
Abstract: PURPOSE:To reduce a loss (at the time of ON) in a regular time while minimizing a sharp rise of a main circuit voltage at the time of switching, by providing a means of making the absolute value of a gate voltage of a semiconductor element rather low at the time of turn-OFF of the element and increasing this absolute value of the gate voltage gradually when the element turns in an OFF state and a means of increasing the absolute value of the gate voltage gradually at the time of turn-OFF. CONSTITUTION:When a signal input 01 changes from an OFF instruction over to an ON instruction, a reverse bias switch 3-2 turns OFF and a forward bias switch 3-1 turns ON. In this initial state, an equivalent capacity CS being parasitic between a gate G and an emitter E of a voltage driven type semiconductor element 6 is charged with electricity of a voltage -E2. Besides, a voltage E1 of a forward bias power source 1 is impressed between the gate G and the emitter E of the voltage driven type semiconductor element 6. In this case, a gate voltage VGE rises at the initial value -E2, a final achievable target value E1 - VZD1 and a time constant CS XRG. Thereafter, the gate voltage VGE increases, a charging current of the equivalent capacity CS decreases, a Zener diode ZD 1 is thereby put in an OFF state, and the gate voltage rises gradually at a final achievable value E1 and a time constant CS X(RG + R1).

Filed: 1995-06-01
Abstract: PURPOSE: To produce a beautiful pinkish ornament at a low cost by constituting a gold alloy having a compsn. essentially consisting of Au and contg. specified wt.% of Cu and Ir. CONSTITUTION: A pinkisy gold alloy for decoration is constituted of K18 (Au 75% wt.) having a compsn. essentially consisting of Au and contg. 20 to 25wt.% Cu and 0.01 to 5wt.% Ir.

The reason for regulating the Ir content to 0.01 to 5% is that improvement can not be shown in its workability and castability in the case of <=0.01% and a preferable color can not be obtd. in the case of >=5%. In addition to the same, the balance one or plural kinds selected from Zn, Ni, Fe, Ag, Co, Rd, Rh and Pt are incorporated therein. Thus, the K18 pinkish gold alloy free from the generation of defects such as cracking can be provided.

Filed: 1978-11-01
Abstract: PURPOSE: To improve the switching speed of a semiconductor device by forming an ion implanted layer not affected by conductivity type at predetermined portion in a semiconductor substrate and collecting diffused gold in the layer.  
     CONSTITUTION: A P-type impurity is adhered at 4 through an opening 3 of the insulator film 2 of an N-type substrate 1, argon (Ar) ion or the like is implanted without adverse effect to its conductivity to thereby form an ion implanted layer 8 in parallel with the main surface in predetermined depth. It is diffused from the layer 4 by heat treatment, a P-type base layer 5 is formed so as not to reach the layer 8. Then, phosphorus is diffused in part of the layer 5 to thereby form an N- type emitter layer 6 thereat, gold 7 is deposited on the substrate 1. Then, it is  thermally treated to thereby diffuse gold in the layer 7 into the entire substrate.  Finally, electrodes are provided on the substrate 1 and the layers 5, 6. According  to this configuration, the gold is collected greater in the layer 8 due to infinitesimal  crystal strain residued thereat even after the heat treatment so that the life of minority carrier is short in the layer 8. Accordingly, in operation, the life of the minority carrier of the collector layer is sufficiently short to thereby improve the  switching speed of the semiconductor device.
