Title: Production of barium titanate porcelain semiconductor
Inventor: NISHI TETSUYA
IPC: C04B35/46
Filed: 1989-08-03
Abstract: PURPOSE:To obtain BaTiO3 porcelain semiconductor having small room- temperature resistivity and large building-up width of resistivity at >= Curie point by blending a BaTiO3 base composition containing a Curie point transfer substance with specific amount of Sb2O3 and Nb2O3 as a semiconductor forming agent. CONSTITUTION:A base composition of BaTiO3 containing a Curie point transfer substance such as SrCO3 is blended with 0.09-0.13mol% based on the composition of Sb2O3 and 0.04-0.06mol% Nb2O3 as a semiconductor forming agent. The mixture is blended by a ball mill for 6-40 hours in a wet state, filtered, dried and calcined at 1,000-1,300 deg.C for 1.3 hours. Then the calcined blend is ground, granulated, molded and calcined (at 1,300-1,400 deg.C for 0-10 hours) to give a BaTiO3 porcelain semiconductor useful as low-resistant PTC element, etc., in a circuit having low current density.

Abstract: PURPOSE: To inexpensively form matched glass to metal sealing with a single process by heating glass and metal having similar thermal expansion coefficients in the atmosphere containing water vapor, gaseous hydrogen and inert gas in a specific volume ratio, melting the glass and sealing to the metal.  
     CONSTITUTION: The glass (e.g. boron-silicate glass) and the metal (e.g. Cr-Fe) alloy) having similar thermal expansion coefficients are prepared. The glass and metal are heated at least at m.p. of the glass in the atmosphere incorporating about 0.5-25 vol.% water vapor, about 0-5 vol.% gaseous hydrogen and the balance of inert gas (e.g. gaseous nitrogen). The glass is melted and the melted glass is heated for a time sufficient to allow the melted glass to unite with the metal, thus airtight glass to metal sealing not containing bubbles is formed.

Title: Drill screw
Inventor: UEDA TAKASHI
IPC: F16B25/10
Filed: 1996-07-31
Abstract: PROBLEM TO BE SOLVED: To improve dimensions of a hole before threading so as to heighten connecting strength and reduce bouncing of a tip part of drill part so as to be able to connect positively and efficiently at a fastening point by making the diameter of a peripheral part cutting edge smaller toward the tip of the drill part. SOLUTION: In a drill part 30, a peripheral part cutting edge 34 is formed along the internal wall surface 32 of a drill groove 31 and the peripheral surface of the drill part 30, and a tip part cutting edge 35 is formed along an intersecting line between the internal wall surface 32 and a tip part 36 of the drill part 30. The diameter of the peripheral part cutting edge 34 is made smaller toward the tip of the drill part 30. Accordingly, even though a hole- before-threading cut by the tip part 36 is of irregular shape, the hole-before- threading is shaped toward the root of the drill part 30 so as to be formed into regular dimensions. A sufficient thread groove can thereby be formed at the time of tapping by a following thread part 20 so as to be able to obtain larger fastening torque.

Title: Wet type friction material
Inventor: SUZUKI ATSUSHI
IPC: C08J5/14
Filed: 1998-07-16
Abstract: PROBLEM TO BE SOLVED: To obtain a wet type friction material which does not allow falling off of carbon particles during use and which can prevent change of frictional characteristics which is caused by such falling off of carbon particles. SOLUTION: The friction material has carbon particles added to the frictional sliding surface to improve heat resistance and durability but carbon particles are removed from the outermost surface part of brake lining 3 to form no carbon layer in the frictional surface 1 in order to prevent falling off of carbon particles during use.

Abstract: PURPOSE:To enable stable measurement, by providing a water absorbing high polymer layer on a measuring electrode and an counter electrode to form a stable liquid film layer. CONSTITUTION:A conducting carbon paste is printed on an insulating substrate 8 consisting of polyethylene terephthalate by screen printing and then dried by heat to form an electrode system consisting of a measuring electrode 6 and a counter electrode 7 and a lead section.

Title: Electrical heating nozzle
Inventor: NISHIKAWA MASAMI
IPC: B22D41/60
Filed: 1986-08-27
Abstract: PURPOSE:To uniformly generate heat in a nozzle body to prevent solidification of a molten steel by combining high resistance refractories, insulating refractories and resistance exhothermic refractories in such a manner that the current from the solderless electrode disposed to the upper part of the nozzle body does not bypass the two poles thereof. CONSTITUTION:This electrical heating nozzle 1 is made into inside and outside two-layered structure. The parts from an upper port 2 to the top of a molten steel outflow port 3 only in the angle position at each end of one diameter of the nozzle body are made of the insulating refractories 12, 12 from the inside to the outside surface. Only the refractories of the outside layer only in the specified width area on both sides of therespective insulating refractories are substd. with the high resistance refractories 11, 11. The resistance exhothermic refractories 10, 10', therefore, face each other with the insulating refractories 12, 12 in-between and are united and electrically connected to each other at the bottom end of the nozzle where the insulating refractories 12 and the high resistance refractories 11 do not exist. A current course 7 flows mainly in the resistance exhothermic refractories 10' of the inside layer. This method is thus effective for an increase in calorific value and heat accumulation.

Title: Winding control device
Inventor: KONDO TORU
IPC: B65H23/198
Filed: 1993-08-16
Abstract: PURPOSE:To carry out excellent tension control by correcting a speed reference of the first pinch roll so that a load of the first pinch roll to the whole load tension in a section between a position, in which the tail, end of a material to be rolled passes a rolling device, and a position, in which the material to be rolled reaches the first pinch roll, is reduced according to the movement of the tail end of the material to be rolled. CONSTITUTION:When a speed reference of the first pinch roll 4 is corrected to a larger side according to the movement of the tail end of a material 2 to be rolled which passes through a rolling device 1, the tension borne by the first pinch roll 4 can be gradually transferred to the second pinch roll 5. In this way, most of the tension borne by the pinch roll 4 is transferred to the pinch roll 5, and then, the tail end of the material 2 to be rolled passes through the first pinch roll 4. As a result, a change in the tension of the pinch roll 5 when the material 2 to be rolled passes through the pinch roll 4 can be suppressed, so that a slip, which is generated because of the change in the tension, of the material 2 to be rolled can be prevented.

Title: Defrosting controller for refrigerating show-case
Inventor: SUDO HARUHIKO
IPC: A47F3/04
Filed: 1994-08-04
Abstract: PURPOSE:To prevent a waste defrosting operation from being carried out by detecting the operating current of a fan motor, comparing the operating current with a reference value and starting a defrosting when the operating current exceeds the reference value. CONSTITUTION:The operating current of a fan motor 7 is detected by a current transformer 13. A current signal thereof is full-wave rectified by a current detecting circuit 14 and the obtained signal is converted into a voltage signal V by a current/voltage converting circuit 15. This voltage signal V is compared with the reference voltage V0 of a reference voltage generating circuit 16 by a comparator 17. When the voltage signal V exceeds the reference voltage V0, a defrosting signal is output to a heater drive circuit 18 from the comparator 17. The heater drive circuit 18 outputs a gate signal to a thyristor 19 to turn it on. As a result, an electromagnetic contactor 20 is excited, a solenoid valve 9 is deenergized by turning off is auxiliary contact 20a and a defrosting heater 10 is turned on to start a defrosting. Thus, the rise of temperature in a chamber due to the defrosting operation can be controlled to a minimum degree as low as possible.
