Patent JP-S58142562-A (JP)
Title: Semiconductor device
Inventor: OONISHI YOSHIAKI
IPC: H01L27/06
Filed: 1982-02-19
Abstract: PURPOSE:To prevent the breakdown due to resistance dispersion and thus contrive the increase of the clamp effect, by individually connecting clamp resistances to a P-N junction part. CONSTITUTION:A clamp diode 4 is connected to the gate 1 of an Nch FET2 of CMOS by an A wiring 3, and the P-N junction 5 is connected in parallel thereto. In the input part of the package 20 of this IC chip 9, an individual resistance 21 of 500-1,000OMEGA is connected between the input pin and pads 16 which require clamp. Therefore, the dispersion such as diffused resistances can be reduced as small as possible. Unlike a monolithic structure, direct influence to t P-N junction part is not generated, accordingly it can be always controlled to the desired resistance value, and therefore the clamp effect can be increased. For the clamp resistance, normal resistance wires and a various kind of resistances can be used, and it can be inserted to the outside of a package.

Title: Heat exchanger with louver fin
Inventor: ITOU MASAAKI
IPC: F28F1/32
Filed: 1979-03-05
Abstract: PURPOSE: To improve heat transfer coefficient by a method wherein fins are bent slantly relative to the direction of gas flow, and louvers are cut and set up in parallel with the gas flow direction.  
     CONSTITUTION: Fins 1 are bent into S-shape relative to gas flow direction G. Heat transmitting pipes 3 are flat in shape, and the fins 1 are arranged in parallel with each other between the pipes 3. As a result, the fins 1 are slanted relative to the gas flow direction G in their whole extension range, and the lines connecting root ends 1b and free ends 1c of the fins 1 are parallel to the gas flow direction G; therefore, there is no portion that is not contacted by the gas flow. In addition, since the louvers 2 are parallel to the gas flow direction G, they do not render the gas passages narrower, and heat transfer coefficient is improved.

Title: Smelting method of zinc by blowing
Inventor: GOTOU SAKICHI
IPC: C22B5/16
Filed: 1983-02-18
Abstract: PURPOSE:To continue a steady operation in a condenser while decreasing the generation of dross and improving a winning rate of zinc by floating lumped or granular coke at all times on the matte surface in a smelting furnace and sealing the slag surface. CONSTITUTION:Sintered zinc ore is changed together with a reducing agent and air enriched with oxygen into a smelting furnace and is smelted. The formed zinc vapor is condensed and captured with a condenser provided integrally with the smelting furnace. Coke powder and/or pulverized coal, etc. are used as a reducing agent in the smelting stage and the top surface of the slag phase formed in the smelting chamber of the smelting furnace is covered with said coke powder or pulverized coal. Then, a substantial injection depth is assured and even if the sintered zinc ore and reducing agent floats temporarily on the matte surface, these powder materials are captured by the coke layer and the scattering thereof to the condenser is prevented.

Title: Manufacture of rack for rack-and-pinion type steering
Inventor: SUGIYAMA EIHIKO
IPC: B62D3/12
Filed: 1988-02-04
Abstract: PURPOSE:To manufacture a convex rack easily by heating near the central part of a rack material at a temperature lower than those at the both ends, and executing a forging process in the condition to give a temperature incline in the axial direction of the rack material. CONSTITUTION:When a convex rack with a size larger as being closer to the center is manufactured, an upper pattern 4 to form teeth 2 to a rack material 1 and a lower pattern 5 to form a rack guide 3 to the rack material 1 are prepared as metal molds. And the rack material 1 heated at the center at a temperature lower than those at the both ends is the heating process is placed between the upper and lower patterns 4 and 5, and a striking force is applied to forge to manufacture a desired rack. Since the deformation resistance at the center of the rack material 1 is larger than those near the both ends in this case, the elastic deformation of the upper and lower patterns 4 and 5 is produced larger at the center than at the both ends, and the teeth 2 of the rack are also larger at the center than at the both ends. Consequently, the rack guide 3 is also made larger as being closer to the center.

Title: Method for removing light contaminant from pulp slurry and back flow type hydrocyclone cleaner used therein
Inventor: JIYATSUKU JIEE MASHIERUBUIKUTS
IPC: B04C5/107
Filed: 1987-02-06
Abstract: A reverse hydrocyclone cleaner (10) for removing light contaminants from pulp slurry has a housing defining a hydrocyclone separating chamber (20). Pulp slurry is fed into the separating chamber adjacent an upper end (28) thereof to form an outer helically and downwardly moving slurry stream relatively free from light contaminants, an inner pulp stream containing a substantial amount of said light contaminants and an air core within said inner stream. An overflow orifice (44) is located adjacent an upper end of the separating chamber, and an underflow orifice (46) is located adjacent a lower end of the separating chamber to remove the outer pulp stream relatively free from light contaminants. A centrally located blocking finger (38, 40) is located in the underflow orifice. The outer pulp stream passes around the blocking finger, which has a substantially flat upper surface (54) of sufficient diameter to define lower limits of both the air core and the inner pulp stream and cause the inner pulp stream containing a substantial amount of said light contaminants to travel upwardly in the separating chamber in a helical manner around the air core to and through the overflow orifice.
