Inventor: OTOMO YOSHITAKA
IPC: B03C5/00
Filed: 1995-04-27
Abstract: PURPOSE: To make clarified water by the dust collecting action and electrolytic action obtained by artificial high voltage discharge. CONSTITUTION: A dust collecting plate 2 and a discharge electrode 5 are arranged in a water tank 1 in opposed relationship and high voltage is applied across both of them to generate discharge and impurities such as dust present in the water within the water tank are attracted to the dust collecting plate and the water in the water tank 1 is electrolyzed by discharge to reduce the oxidation caused by iron rust of the water tank or a water sending pipe to obtain clarified water. Further, the water after electrolysis is filtered and heat- treated to make drinking water.  A drinking water making apparatus utilizing high voltage discharge is constituted by arranging the dust collecting plate formed into a metal reticulated structure in the vicinity of the side wall of the water tank and arranging the discharge electrode at the central part of the water tank and connecting a high voltage generator 8 across the dust collecting plate and the discharge electrode.

Title: Production of photoconductive paint composition
Inventor: SUMINO FUMIO
IPC: G03G5/05
Filed: 1987-06-05
Abstract: PURPOSE:To shorten the time required for dispersion of a pigment with no adverse influences exerted at all on electrophotographic characteristics by mixing the pigment which is not subjected to a heating treatment to the pigment which is subjected to the heating treatment at an adequate ratio. CONSTITUTION:The pigment which is not subjected to the heating treatment is added and mixed to and with the pigment which is subjected to the heating treatment at 1-10wt.% in a stage for dispersing the pigment after previously subjecting the pigment to the heating treatment with a main solvent at the time of a dispersion stage. The required dispersion time for the pigment subjected to the heating treatment is generally about 2-3 if the required dispersion time for the pigment which is not subjected to the heating treatment is assumed to be 1. The dispersion time for the pigment is thereby reduced without exerting the adverse influence on the electrophotographic characteristic if the pigment subjected to the heating treatment is added and mixed to and with the pigment which is not subjected to the heating treatment in the solvent.

IPC: G06F11/30
Filed: 1978-11-14
Abstract: PURPOSE: To make it possible to detect anomaly of a device controlling micro computer easily by combining a unilateral element and a capacitive element and generating a prescribed potential at the output.  
     CONSTITUTION: Clock pulses are inputted to micro computer 2, and pulses of, for example, 100Hz are sent from buffer 3 on a basis of a program determined previously. These pulses are supplied to diodes 8 and 9 through capacitor 7 of detection circuit 1. Capacitor 11 is connected between the anode of diode 8 and the cathode of diode 9. Consequently, the potential at output terminal 6 is negative when regulator pulses are outputted from buffer 3, and meanwhile, terminal 6 is zero- potential when pulses disappear or the frequency of pulse is a value below 50Hz. As a result, normalcy of the computer can be detected by detecting the potential at terminal 6.

IPC: C22C38/00
Filed: 1980-10-09
Abstract: PURPOSE:To eliminate the abrasion of a die, the seizure of die and a panel, or a galling flaw of the panel that occur particularly during press working by melt spraying a powder material for melt spraying of a specific composition thereby forming a melt sprayed layer of high resistances to abrasion galling. CONSTITUTION:A powder material consisting of >=40 Ni, 3-8 Si, 0.1-0.5 B, 0.3-2 Nb, 0.2-1.5 C by wt%, and the balance Fe and unavoidable impurities are melt sprayed. Here, the Ni prevents seizure and galling phenomena, and requires the above-mentioned amount. The Si increases hardness, and below the lower limit, there is virtually no effect and abrasion resistance is insufficient. Above the upper limit, the abrasion resistance does not increase markebly, and conversely, it shows a tendency toward degradation of galling resistance. The B increases hardness and improves abrasion resistance and the effect thereof is much higher in the presence of the C, but above the upper limit, it leads to cracking of the melt sprayed layer and degradation in machineability after melt spraying. The Nb lowers crack sensitivity and improves abrasion resistance, but above the upper limit, it lowers galling resistance. The C improves abrasion resistance but above the upper limit, it flows the panels.

Abstract: PURPOSE: To effectively eliminate defects which are caused when impurity ions are implanted into a semiconductor substrate, by sequentially projecting a laser beam of high output and short pulse width and another laser beam of low output and long pulse width in arbitrary order upon the implanted part of the substrate after the implantation to anneal the implanted part.  
     CONSTITUTION: Field SiO 2  films 2 are produced on both the ends of a p - -type Si substrate 1. A gate oxide film 3 and a gate electrode 4 are provided on a device zone. Ions of As are implanted into the exposed part of the substrate 1 to produce ion-implanted layers 5, which are to be a source and a drain. An Nd-YAG laser beam of 30 nanoseconds in pulse width and about 33 MW output is projected upon the layers 5 while the energy intensity of the laser beam is maintained at about 1J/cm 2 , thereby firstly annealing the layers. Another Nd-YAG laser beam of 500 nanoseconds in pulse width, 20 MW in output and 10J/cm 2  in energy intensity is then projected upon the layers, thereby secondly annealing them. The layers 5 are thus changed into n + -type regions 6, 7. In that case, an amorphous layer produced before is recrystallized and the properties are improved.
