Title: Highly heat-resistant aluminum alloy based corrosion-resistant pigment
Inventor: UCHIMURA EIKICHI
IPC: C22C21/10
Filed: 1984-05-08
Abstract: PURPOSE:To provide the titled pigment which has high corrosionproofness even when heated to high temp., by incorporating a trace amount of In or Sn in an Al alloy contg. Zn and Si. CONSTITUTION:The titled pigment consists of 20-50wt% Zn, 8-25wt% Si, 0.01-0.2wt% In and/or 0.01-2.0wt% Sn, the balance being Al and inevitable impurities. When 50wt% or more Zn is added to Al, a sacrificial anode effect on Fe is obtd. However, when heated to a high temp., the corrosionproofness is greatly reduced. It is known that when an appropriate amount of Si is added, an Al alloy powder pigment having high corrosionproofness and resistance to heat at 700 deg.C can be obtd. By adding a trace amount of In or Sn, a pigment can be obtd. which has high corrosionproofness even when heated to 800 deg.C.

Title: Character image data forming method and device therefor
Inventor: ASAI NORIHIKO
IPC: G06T11/20
Filed: 1996-04-12
Abstract: PROBLEM TO BE SOLVED: To obtain a character output of high quality in which the load on a CPU and unclearness of a character are reduced and distortion of a shape is not conspicuous. SOLUTION: The density gradation number deciding means judges complexity for each region of each character image data (S4510), and decides the number of gradations of density in every region so that as complexity becomes lower the number of gradations of density is decreased. An image data forming means selects the density gradations in accordance with an occupancy area of a character indicated by outline data for each pixel from the number of gradations of density decided by the density gradations number deciding means (S4530, S4540), and decides it as the density gradations of each pixel of character image data (S4550).

Title: Observer control system
Inventor: TORII NOBUTOSHI
IPC: G05B13/04
Filed: 1990-04-05
Abstract: PURPOSE:To increase a state feedback gain by excluding a non-linear item, which is estimated by a sliding mode control means, from a switch input to an observer. CONSTITUTION:A sliding mode control means 2 generates a switch signal T1 by respective items such as the error amount of a position, dynamical friction, acceleration and gravity or the like. Therefore, since a state variable can be estimated only with a linear item by an observer 7 when applying the switch signal T1 while excluding the gravity item or the like as the non-linear item from this signal, the state variable can be estimated without being affected by the non-linear item. Then, this estimated state constant Xn without offset is used. Thus, the state feedback gain of a control system can be increased.

IPC: H01L21/8222
Filed: 1983-05-26
Abstract: PURPOSE:To enable construction of element suitable for a high tension resisting IC which requires a small area by providing an inclined concentration n-layer which has an impurity concentration distribution decreasing from the n<+> layer to the n<->layer near the exposed surface. CONSTITUTION:In a polycrystalline Si base 1, an n<->type single crystal Si island 3 is formed through an oxidized film 2 for insulation and separation and in the island 3, a p-layer 4 for anode and an n<+> layer 5 for taking out cathode are formed. Between a high concentration n<+> layer for channel cutting and an n<-> region 3, an n-layer 15 for electric field mitigation having gradually decreasing impurity concentration from the n<+> layer 6 toward the n<-> type Si 3 is provided. Since the n-layer is made to have inclination of concentration, a region near the field plate can be made low concentration and field concentration can be reduced whereby the n-layer for field mitigation can be formed nearer the field plate and an area required for a high tension resisting element can be reduced.

Abstract: PURPOSE:To provide a method for easily welding and joining precoated metallic plates to each other by subjecting one surface of one of these precoated metallic plates to conductive coating at the time of joining the precoated metallic plates. CONSTITUTION:The precoated metallic plate B having a coating film 2 contg. a conductive material on one surface is used as the one precoated metallic plate. Both surfaces of the joining end of the other precoated metallic plate A are held and superposed with the joining end of the precoated metallic plate having such conductive coating film surface as a welding surface.

Title: Phase controlling circuit
Inventor: ADACHI TADASHI
IPC: H02M3/156
Filed: 1982-05-28
Abstract: PURPOSE:To reduce the effect of variations of the power supply voltage and to keep the load at a constant level, by turning on the load via a TR at the front edge of a half wave of an AC power supply, turning off the load with the 1st prescribed potential in the half wave and then turning on again the load with the 2nd prescribed potential. CONSTITUTION:An AC power supply 7 is rectified 8, and the voltage is detected 9. Then the electric power is supplied to the load 11 via a TR10 of Darlington connection. A TR30 and the TR10 are turned off and on at the front edge of each half wave of the power supply 7, and the load 11 is turned on. The voltage increases at a point (a), and therefore the voltage increases also at a point (b) and the joint between resistances 19 and 20. Then an SBS24 is broken over and turned on, and a TR26 is also turned on. An output is set at L. An output (e) of an exclusive OR14 is set at H since a point (d) is set at H, and a point (f) is set at L to turn off a load current. The level of a capacitor 23 rises up as the phase advances. Then an SBS25 is broken over and turned on, and a TR27 is also turned on. The point (d) is set at L, and the OR14 delivers L. Then the point (f) is set at H to turn on the load current. Thus the phase is controlled to generate the stable electric power.

Abstract: PURPOSE:To obtain the toner which is uniformly dispersed with constituting components, such as dyes, pigments and charge control agent, in a binder resin and which has excellent colorability and electrostatic charge characteristics by specifying the weight average particle size of the binder resin. CONSTITUTION:The toner which is uniformly dispersed with constituting components, such as dyes, pigments and charge control agent, in the binder resin, is produced by preparing the binder resin to >=0.1mm and <=1.0mm average particle size with respect to the micro unit of the particle sizes of the other toner constituting materials and <=3mm max. particle size, melting and kneading the materials after mixing and stirring, then grinding and classifying the mixture after cooling the melt. The constituting components, such as pigments, are not uniformly dispersed in the binder resin and unstable images are only obtd. if the average grain size of the binder resin particles exceeds 1.0mm and the max. particle size exceeds 3mm. The contamination in the device by the splashing of the toner arises if the average grain size is below 0.1mm.

Title: Curing method for casting mold surface
Inventor: UNOSAKI NAGATO
IPC: B22C9/12
Filed: 1985-04-27
Abstract: PURPOSE:To improve the strength of a casting mold by penetrating an adhesive agent liquid to the surface of a green sand mold so that the liquid reacts and solidifies by contacting with the moisture of the mold. CONSTITUTION:Green sand is first squeezed to form a master mold 3 in a molding flask 1 and to form a cavity surface 2. The adhesive agent liquid which reacts and solidifies with the moisture as a catalyst is coated on the surface 2 and is penetrated therein. The master mold 3 penetrated with the adhesive agent liquid is thereafter rested in the atmosphere. The adhesive agent liquid solidifies in several minutes by contacting with the moisture incorporated into the mold 3 according to the above-mentioned method. A hard cured surface 4 is thus formed on the cavity surface of the mold 3. The strength of the cavity surface 2 of the green sand mold 3 and the mold 3 is thereby remarkably improved.
