Title: Production of iron oxide for ferrite
Inventor: KAWAYOSHI YATSUHIRO
IPC: C01G49/02
Filed: 1988-02-15
Abstract: PURPOSE:To increase the yield of the iron component by recovering iron of low purity from the blow solution in which the impurities of by-products is concentrated in the recovery process, when iron oxide of high purity is recovered by removing impurities in the waste from the steel pickling. CONSTITUTION:The waste solution from steel pickling is concentrated, the impurities are filtered off, and the filtrate is fed to the installation for producing iron oxide of high purity such as a calcination furnace to give iron oxide of high purity. In the meantime, a part of the residue on the filtration is recycled to the concentration process, the remaining is fed together with the blow solution in which the impurities from the concentration process is concentrated to the installation for producing iron oxide of low purity to produce iron oxide of low purity. The concentration operation is carried out by the evaporation or vacuum concentration or the flocculation using a flocculent such as a cationic polyacrylamide. The high-purity iron oxide is used in a toner ferrite, while the low-purity iron oxide is in Indian red coating.

Title: Refrigerant transporting hose
Inventor: ARIMA TETSUYA
IPC: F16L11/08
Filed: 1996-02-20
Abstract: PROBLEM TO BE SOLVED: To improve pressure tightness and durability of a refrigerant transporting hose. SOLUTION: A refrigerant transporting hose is provided with an inner rubber layer 10, a resin layer 11, a first reinforcing layer 12, an intermediate rubber layer 13, a second reinforcing layer 14 and an outer protective layer 15 which are sequentially laminated. The inner rubber layer is made of butyl rubber having moisture transmitting resistance. The resin layer is made of polyamide resin. The first and second reinforcing layers are formed by spirally winding reinforcing yarns formed by twisting a plurality of polyester filaments around the outer peripheral surface of the inner rubber layer. Since the resin layer has the high temperature modulus M50 in the range of 25 to 35kgf/cm<2> and has it higher than that of general butyl rubber, high viscosity can be maintained in vulcanization, and blowoff is hardly generated caused by resin flowing from between the reinforcing yarns.  Therefore, slip of the reinforcing yarn in vulcanization is prevented, deviation in the lateral direction of the reinforcing yarns is restrained, and yarn jogging performance of the reinforcing yarns is improved. As a result, pressure tightness and durability of a refrigerant transporting hose can be improved.

Title: Driver circuit of laser diode
Inventor: NAKAMURA TERUHIRO
IPC: H04B10/2507
Filed: 1990-02-13
Abstract: PURPOSE:To inhibit a ringing, which is generated in an optical signal, by a method wherein the driver circuit of a laser diode is provided with a variable capacitor, whose terminal on one side is connected to the cathode of the laser diode and whose other terminal is earthed. CONSTITUTION:In the case a capacitance of a variable capacitor C is small, a rise time and a fall time of a drive current, which is fed to a laser diode LD, are changed steeply, while when the capacitor C is adjusted and the capacitance is made large, the rise time and the fall time of the drive current become slow. Accordingly, such a rise time and a fall time as not generating a ringing in an optical signal outputted by the diode LD can be easily set by setting properly the capacitance of the capacitor C.

Title: Single-phase autotransformer
Inventor: KOJIMA TAKESHI
IPC: H01F30/02
Filed: 1981-03-09
Abstract: PURPOSE:To make the voltage of tertiary winding constant regardless of the position of a tap while maniaturizing the titled transformer and reducing cost by winding series winding and shunt winding on the first main leg and winding the tertiary winding, tap winding and exciting winding on the second main leg. CONSTITUTION:The tap winding 4, the tertiary winding 30 and the exciting winding 50 are wound on the main leg 7B, the winding 4 is connected in series with the neutral point side of the shunt winding 2, and the winding 50 is connected in parallel with the winding 2 connected in series and both terminals u, v of the winding 4. When voltage between u and v is made constant and voltage between U and v is varied, the excitation of the core leg 7B does not change according to the position of the tap because voltage between u and v is constant. Consequently, the voltage of the winding 30 is also constant regardless of the position of the tap, and the induced voltage of the winding 4 is also constant. Accordingly, connection and constitution are simplified because conventional series transformers are unnecessitated, and the titled transformer can be manufactured without extremely enlarging the diameter of the winding because the winding 30 is not wound on the same leg as the shunt and series winding.
