Title: Spherical hematite particle powder and production thereof
Inventor: MORI KEIZO
IPC: C09C1/22
Filed: 1985-04-03
Abstract: PURPOSE:To improve the thermal stability of maghematite particle, by adding a silicate in the production of magnetite particle used as a starting particle and oxidizing the magnetite particle having improved sphericity at a relatively high temperature. CONSTITUTION:An aqueous solution of a ferrous salt is made to react with 0.8-0.99 equivalent (based on Fe<2+> in the aqueous solution of ferrous salt) of an alkali hydroxide to form ferrous hydroxide colloid. In the above process, the alkali hydroxide or the reaction system is added with 0.1-5atom% (in terms of Si based on Fe<2+>) of a water-soluble silicate. An oxygen-containing gas is passed through the mixture while heating the mixture at 70-100 deg.C and the system is added with >=1 equivalent of an alkali hydroxide based on Fe<2+> remaining in the reaction mother liquor. Produced magnetite particle is oxidized by heating in air at 500-800 deg.C to obtain spherical maghematite powder having a bulk density of 0.4-1.25g/cm<3>.

Title: Stable operation method of vector controller
Inventor: YAMADA KATASHIGE
IPC: H02P21/00
Filed: 1996-03-27
Abstract: PROBLEM TO BE SOLVED: To ensure a stable operation at the time of saturation of output volt age. SOLUTION: An excitation-current command Id' and a torque-current command Iq' are output, and an induction motor 4 is supplied with an AC current from an inverter 13 so that an excitation-current detecting value IdFB displaying an excitation current and a torque-current detecting value IqFB indicating a torque current reach command values respectively. When output voltage from the inverter 13 is not saturated, the excitation-current command Id' is kept constant. When the output voltage from the inverter 13 is saturated, both the excitation-current command Id' and the torque-current command Iq' are reduced.  The excitation-current detecting value IdFB displaying an actual excitation current is reduced up to the command value, and the torque-current command Iq' is increased and a torque current is augmented by a section compensating torque shortage by the decrease of the excitation current.

Title: Adhesion structure of rubber and fiber and its adhesion method
Inventor: ISHII TAKASHI
IPC: B29K21/00
Filed: 1994-04-11
Abstract: PURPOSE:To obtain an adhesion structure of rubber and fiber with a high adhesive force by a method wherein a fiber treated with a blend adhesion treating agent prepared by compounding a specific percentage of a colloidal silica by weight to the resin content of a mixture adhesive RFL is bonded to a rubber. CONSTITUTION:A fiber is impregnated with a blend adhesion treating agent prepared by compounding 5-50wt.% solid content of a colloidal silica to the resin content of a mixture adhesive of a resorcin formaldehyde resin and a rubber latex, thereafter being passed through a high-temperature drying furnace to be dried to be produced as a blend adhesive treated-fiber. After that, the blend adhesive-treated fiber is bonded to a rubber. The loading amount of the colloidal silica is 5-50wt.% to the solid content of the RFL. In this manner, the blend adhesion treating agent has a good stability and a superior adhesion strength to an adherend. If the loading amount is not more than 5wt.%, enhancement of an adhesion cannot be recognized. The loading amount more than 60wt.% causes separation of the treating agent, resulting in a failure to enhance an adhesion and a disadvantage from a cost standpoint.

Abstract: PURPOSE:To decrease the number of transistors to be used by making the output of a decoder correspond to the input of the NOR circuit of a ratio and connecting two sense amplifiers whose threshold voltages are different to the output of the NOR circuit of the ratio. CONSTITUTION:Output signals 01-0n of the decorder are supplied to transistors 22-24, and when only one decoder output is selected, an output voltage 25 of a NOR circuit 11 of the ratio is shown by a level 31, and when plural outputs of the decoder are selected, the value of the output voltage 25 lowers as shown by a level 32. When the threshold value of a sense amplifier 26 is set between the levels 31 and 32, the malfunction of the decoder can be detected. All of decoder output signals O1-ON are LOW, the output voltage 25 remains at a HIGH level 33, it cannot be distinguished from the case of a normal action and therefore, this trouble can be detected by a sense amplifier 27 whose threshold value is set between a supply voltage VDD and the level 31. Thus, the number of transistors to be used can be decreased.
