IPC: C25D5/04
Filed: 1990-03-27
Abstract: PURPOSE:To form an electroplating layer uniform in thickness by changing the distance between electrodes in accordance with the area of a material to be treated and electroplating one or both sides of the material. CONSTITUTION:An anode 12 and a material 14 to be plated are opposed in a plating soln. 13 in a plating bath 11, air is supplied from the injection port 16 of an air injection pipe 15 to agitate the soln. 13, and the material is electroplated. In this electroplating method, the distance (d) between the electrodes is changed in accordance with the area of the material 14. A conductive mask having a pattern opposite to the pattern to be formed is arranged on the plating surface to form an electroplating layer over the whole surface, and then the mask is removed. The cross-sectional area of the bath 11 parallel to the anode 12 is preferably increased gradually. Furthermore, the injection pipe 15 is formed with a cylinder having an outlet and an adjuster placed thereon to change the amt. of air to be injected and to adjust the agitation of the soln. 13.

Title: Method for synthesizing diamond
Inventor: SAITO YUKIO
IPC: C23C16/26
Filed: 1986-04-07
Abstract: PURPOSE:To synthesize diamond at a high rate and a low pressure by impressing electromagnetic energy on a gaseous mixture consisting of a gaseous hydrocarbon, gaseous H2, and gaseous O2 or an inorg. gas contg. O2 in a reduced- pressure reactor to generate a plasma reaction. CONSTITUTION:A hydrocarbon 1, H2 2, and O2 or an inorg. gas 3 contg. O2 are measured by mass flowmeters 4 and then mixed. The mixture is supplied to the reactor 5 whose pressure is reduced by a vacuum pump 11. A high-frequency wave is impressed on the supplied gaseous mixture from a high-frequency oscillator 6, and the mixture is formed into plasma. The H2 and O2 are decomposed in the plasma 7 to generate radicals. The hydrocarbon is decomposed by a hydrogen abstraction reaction due to the radicals or by electrons having high energy in the plasma, and diamond and graphite are deposited on a substrate 8 heated at several hundreds degree Celsius. The graphite reacts with the O2 radical and H2 radical and is removed, and diamond is selectively formed on a silicon substrate.

Title: Preparation of flame-retardant
Inventor: INOUE KOUJI
IPC: D21H21/14
Filed: 1980-06-10
Abstract: PURPOSE: To provide a flame-retardant having good thermal stability and containing no insolubles from a guanidine salt which suffers thermal discoloring and have a poor thermal stability, by dissolving the guamidine salt in water and treating the solution with a basic anion exchange resin.  
     CONSTITUTION: A guanidine solution dissolved in water is brought into contact with a basic anion exchange resin sufficiently to reduce the content of ammonium salts in the solution to a level of 0.04mol% or lower, based on the guanidine salt, and then the resin is removed by filtration to obtain a flame-retardant having excellent heat resistance. In this process, it is not necessary to prepare a special guanidine salt for the flame-retandant. By the above-mentioned treatment of the guanidine salt which cannot be used due to thermal discoloring, impurities are not increased but, on the contrary, cationic components present as impurities can be removed out of the system, so that a high-purity flame-retardant can be easily prepared.

Title: Protective system for distribution line
Inventor: KATO KAZUAKI
IPC: H03K17/08
Filed: 1991-03-18
Abstract: PURPOSE:To lower the number of power stoppages of the distribution system, and lighten the damage of the distribution line by a fault current by opening or making a thyristor type high-speed switch, prior to the opening operation of the breaker in s substation. CONSTITUTION:For a current sensor 8, if an abnormal current by thrunder surge occurs in the distribution line 3 and it reaches shortcircuit fault or the like, the judging means 12 detects the zero phase current, etc., at the same time with the current change of each phase, and inputs the signal of the line shortcircuit fault into a command circuit 13. The command circuit 13 transmits a trigger signal to the thyristor type high-speed switch (OC) 11 through a signal line 9a, and OC 11 finishes a series of operation of closing itself and opening itself again in a short time, and interrupts an arc current. The breaker in the substation is set to the waiting time for approximately 0.2sec from accident occurrence to opening, so by finishing the making and opening of the OC 11 in this while, the arc current is extinguished. In the substation, the fault current vanishes, and the opening operation of the breaker stops, and the power stoppage of the system is avoided.

Title: Bourdon tube type pressure gauge

IPC: G01L7/04
Filed: 1986-04-08
Abstract: PURPOSE:To reduce the weight of respective parts and minimize the number of them and to facilitate and speed up assembling and adjusting operations by installing an internal mechanism which has a pointer on the inside surface of the standstill part of a Bourdon tube. CONSTITUTION:Measured pressure is transmitted to the Bourdon tube through a pressure lead-in passage 11c and a connecting pipe 12a, and a cap 12b at its free end is displaced slightly in proportion to the measured pressure; and this displacement is transmitted to a sector 17 through a bent part 13b atop a coupler 13 and expanded according to the gear ratio to a pinion 16 engaging it to drive the pointer, so that the pressure value is read on a scale plate. In this case, the displacement of an internal mechanism frame 14 is a little because it is installed at the fixed end of the Bourdon tube. Therefore, this displacement causes no functional trouble and the displacement which drives the pointer is the relative mechanical displacement between the tube tip and internal mechanism frame 14, so that there is little influence upon the performance and accuracy.

Abstract: PURPOSE:To obtain a magnetic recording medium with no curl and superior planeness by using a biaxially oriented poly-p-phenylene sulfide film having specified characteristics as a principal constituent layer. CONSTITUTION:A biaxially oriented poly-p-phenylene sulfide (PPS) film contg. units represented by structural formula I by >=90mol% of the repeating units is used as the principal constituent layer of a base film, and a ferromagnetic layer is formed on at least one side of the PPS film. The characteristics of the base film are allowed to satisfy an equation 2X10<-7=AXC<=5X10<-5> in all directions in the surface. In the equation, A is the coefft. ( deg.C<-1>) of thermal expansion at 120 deg.C, and B is the rate (%) of thermal shrinkage at 120 deg.C. PPS used is required to contain >=90mol% repeating units represented by structural formula II. In case of <90mol%, the crystallizability of the polymer is reduced, so the mechanical characteristics of the resulting film are unsatisfactory. Units of m- phenylene sulfide, ether or the like account for the remaining <=10mol%. PPS is melted and molded into a sheet, and this sheet is biaxially stretched and heat treated to obtain said biaxially oriented PPS film. The preferred thickness is 5-100mum.
