IPC: C04B35/00
Filed: 1987-08-21
Abstract: PURPOSE:To synthesize a superconducting material having minute particle size and high uniformity by mixing each alkoxide of Y, Ba, and Cu in an org. solvent having a specified b.p., hydrolyzing the mixture thereafter by adding water thereto, separating then the solvent from hydrolyzed product by reducing the amt. of water, and calcining the hydrolyzed product. CONSTITUTION:Y alkoxide, Ba alkoxide, and Cu alkoxide are weighed, and mixed in an org. solvent having >=100 deg.C b.p. Then, the alkoxides are hydrolyzed by adding water thereto, and the amt. of water in the solvent is reduced or reduced to zero by removing a part of the solvent by heating.

Title: Double-sided magnetic recording medium
Inventor: OTSU MASAMITSU
IPC: G11B5/718
Filed: 1987-08-21
Abstract: PURPOSE:To eliminate crosstalk by providing a magnetic shielding layer between magnetic recording layers and providing a magnetic shielding layer consisting of a superconductor on the magnetic head-contact surface of at least one magnetic recording layer. CONSTITUTION:The magnetic shielding layer consisting of the superconductor of this double-sided magnetic recording medium is heated to the critical temp. or above by a heater 6 and the hatched part changes from a superconductive state to a normal conductive state at the time of recording and reproducing. The Meissner effect is lost in the normal conductive state and the magnetic shielding effect is annihilated only in the hatched part so that the signal record ing and reproducing to and from the magnetic recording layer 2 are enabled. The magnetic shielding layer 4 may be or may not be the superconductor in this case. The crosstalk between the faces through the base which are heretofore generated with the conventional magnetic recording medium are shielded by the shielding layer 4 and the crosstalk between the two magnetic recording layers are eliminated.

Title: Image forming device
Inventor: OSHIMA KIYOSHI
IPC: H04N1/12
Filed: 1990-08-07
Abstract: PURPOSE:To reduce an error in the control of starting image recording by taking a specified position as reference without making a time required for performing an image forming longer by switching to a smaller moving amount than a moving amount at one step in the period of performing the specified image forming by a moving quantity switching means in the period of detecting whether or not a member is moved to a specified position. CONSTITUTION:When an optical sensor 9 detects a resist mark A, a pulse motor 7 is driven normally at a half step and a recording paper 2 is carried so that the moving amount at one step may equal one half line. When the sensor 9 detects the trailing edge (a) of the mark A, the motor 7 is switched to be driven normally at a full step and the paper 2 is carried so that the moving amount at one step may equal one line. Thus, color slurring among Y, M and C is reduced.

Title: Printer printing control system
Inventor: MORIMOTO TERU
IPC: G06Q40/02
Filed: 1988-08-23
Abstract: PURPOSE:To shorten a printing time and to simplify a control program by decelerating the printing speed of a head to print one line by one movement of the head when a high duty character is detected by a high duty detector. CONSTITUTION:Bits in a printing buffer 3 are added all for one line by a program in a control memory 2 by a high duty detector 6. If 30% or more of duty is detected, it is set to a high duty mode. Then, a third control clock generator 10 generates a control clock to decelerate the printing speed, thereby to decelerate the speed by driving a space motor 8, thereby reducing the substantial duty at a head pin fire interval by decelerating the speed to print one line by one movement of a head 5. Since one line can be printed by the one movement of the head 5, printing time can be shortened as compared with a normal three dividing printings.

Abstract: PROBLEM TO BE SOLVED: To obtain, at a low cost, a candle which is spontaneously put out rapidly at the final extinction stage in burning by winding a nonflammable or flame-retardant member without a gap around the final extinction site of a candle wick. SOLUTION: A nonflammable or flame-retardant member 10 is strongly wound around the final extinction site of a candle wick 4. Since the wick 4 is pressed uniformly and strongly to hinder the capillary phenomenon, the suction of wax is stopped at the final extinction stage and the candle is quickly put out spontaneously. Pref., the member 10 is wound in at least one layer around the wick 4 and is a metallic tape or sheet (e.g. an aluminum tape) which can be bent and wound by fingers or a nonmetallic tape or sheet (e.g. a flame- retardant paper tape). Thus, the objective candle can be produced by a simple work without using a jig.

Title: Liquid fuel combustion apparatus
Inventor: OOMUKAE YOSHIZOU
IPC: F23Q25/00
Filed: 1983-11-08
Abstract: PURPOSE:To completely shut out offensive odor at the quenching time, by completely quenching flame in a moment at the same time when a quenching operation is completed, by providing a shut-off device to the wick elevating part of the titled apparatus. CONSTITUTION:A shutter 12 as a shut-off device is designed to shut off the inside space of a wick elevating part 4 after a wick is descended. When the flame is going to be quenched, a wick 3 is descended down to the quenching position, and then the shutter 13 is moved to shut off the part 4. That is, the upper end of a wick is shut off immediately after the wick is descended, so that the substance to cause offensive odor is prevented from moving to the position where it can satisfy the condition to produce offensive odor. On the other hand, a passage to supply fresh air is formed in the space where the top of a wick elevating part 4 contacts with the bottom of a wick tray. With such an arrangement, odor caused by the substance cannot stay in the space, because the pressure of steam from fuel gas is lowered, the gas is prevented from condensing again, and evaporation of deposited fuel around the part 4 can be promoted, Accordingly, both complete quenching of flame in a moment and complete deodorization at the quenching time can be accomplished at the same time in a liquid fuel combustion apparatus.

Title: Solar heat collector
Inventor: OOSAWA SEIICHI
IPC: F24S10/70
Filed: 1983-11-08
Abstract: PURPOSE:To contrive to reduce the cost and at the same time enable to keep the airtightness by a method wherein iron or stainless steel is employed to a connecting pipe to connect the outer peripheral part of an absorber pipe with the peripheral edge part of the opening of an end plate and cheaper brazing materials, the melting temperatures of which are different from one another, are employed at joining parts. CONSTITUTION:A first connecting pipe 9' made of iron or stainless steel, the melting temperature of either one of which is higher than that of copper, and a second copper connecting pipe 9'' are employed. At the same time, the brazing between the peripheral edge part 5a of the opening of an end plate 5 and the one end side of the connecting pipe 9' is done by copper brazing metal instead of conventional silver brazing metal. The brazing between the other end side of the connecting pipe 9' and the one end side of the connecting pipe 9'' is done by bronze brazing metal. The brazing between the other end side of the connecting pipe 9'' and the outer peripheral part of an absorber pipe 3 is done by phosphor copper or copper brazing metal with low silver content. Stainless steel, the thermal expansion coefficient of which is nearly equal to that of glass is used in the end plate 5 instead of 42-6 alloy. Because the melting temperatures of solders indescending order of height are of copper brazing metal, bronze brazing metal and phosphor copper brazing metal or copper brazing metal with low silver content, said brazings done by the solders with the melting temperatures lower than that of copper solder do not melt the brazed part between the connecting pipe 9' and the peripheral edge part 5a of the opening of the end plate 5 and consequently do not impair the airtightness of said brazed part.
