Title: Manufacture of nonoriented electrical steel sheet
Inventor: MINATO TAKEHIKO
IPC: H01F1/16
Filed: 1986-07-21
Abstract: PURPOSE:To prevent the deterioration of electromagnetic characteristics by rolling with dull rolls by carrying out the rolling with dull rolls at a specified draft during second cold rolling on the downstream side of a process annealing stage. CONSTITUTION:First cold rolling, process annealing and second cold rolling are carried out to provide a final thickness. During the second cold rolling on the downstream side of the process annealing stage, rolling with bright rolls is carried out in the second half on the upper stream side and rolling with dull rolls is carried out at 1-5% draft in the second half on the downstream side. Since the rolling with dull rolls is carried out at such a restricted draft, the surface of the resulting sheet can be made uneven without deteriorating the aggregated texture. Accordingly, a rough surface is ensured and an electrical steel sheet having dullness can be obtd. without deteriorating the electromagnetic characteristics.

Title: Dephosphorizing method for high-manganese alloy
Inventor: KAJIOKA HIROYUKI
IPC: C21C7/076
Filed: 1985-08-02
Abstract: PURPOSE:To easily execute a dephosphorization treatment at a low cost by adding a specific ratio of BaCO3 as a flux to high-carbon ferromanganese contg. P at a high rate and oxidizing part of Mn to MnO by the CO2 formed by the decomposition thereof thereby incorporating MnO into molten slag. CONSTITUTION:The melt of the high-carbon ferromanganese of the high P content contg. >20-% Mn is subjdcted to a preliminary desiliconization treatment in a ladle and thereafter BaCO is added as the flux at 2-9% ratio thereto. An inert gas or oxidizing gas such as Ar, N2 or CO2 in then added to the melt and the melt is stirred. The operation in this stage is executed at a relatively low operating temp. of 1,250-1,400 deg.C and part Mn is oxidized to MnO by the gaseous CO2 formed by the thermal decomposition of BaCO3 so that the molten slag is made strongly basic by BaO and the oxidizing slag incorporated with 2-40% MnO is obtd. The P in the high-carbon ferromaganese is oxidized to P2O5 and is converted to slag by the above-mentioned slag. The dephosphorization refining is thus easily and surely executed.

Title: Controlling method of positioning of carrying object
Inventor: MIYAZAKI YASUAKI
IPC: G05D1/02
Filed: 1982-09-30
Abstract: PURPOSE:To stop exactly a carrying object at a prescribed position by deriving the weight of the carrying object from an accelerating time, and decelerating it along an optimum decelerating curve corresponding to the weight. CONSTITUTION:When carrying is started, a motor 9 is accelerated by the maximum torque. Weight of a carrying object can be calculated from the time required for reaching a prescribed revolving speed. Even in case when the weight of the carrying object is changed, it is unnecessary to measure directly the weight of the carrying object, therefore, an extra trouble can be saved. An operation processing part 5 calculates a decelerating curve in the shortest time in accordance with information from a position detector 12 and a timer 2. The motor 9 is controlled basing on the decelerating curve, and the carrying object is stopped at a prescribed position.

Title: Stepping motor
Inventor: ISHIKURA HISATSUGU
IPC: H02K37/12
Filed: 1993-07-09
Abstract: PURPOSE:To provide a high torque, low cost stepping motor for wide application by extending the axial length of a pectinated tooth pole without increasing the leakage flux. CONSTITUTION:The poles of a stator comprises an inner stator 6, i.e., a hollow tubular inductor pectinated on the opposite sides, and two cup-like outer stators 4, 11, i.e. inductors pectinated on side, disposed on the opposite sides of the inner stator 6. The pectinated tooth poles of the inner stator 6 and the outer stators 4, 11 have tips opposing each other. Since the adjacent tooth poles do not oppose each other over the entire length thereof, leakage flux 21 is reduced. Leakage flux 21 does not occur at the root of tooth pole where the flux density is high, because the tooth poles are not arranged contiguously thereat.

Abstract: PURPOSE:To shorten a vulcanization time and to reduce a lowering of close adhesiveness due to the shrinkage of a rubber film even in radiation vulcanization by using a specific resin in an adhesive and compounding a crosslinking agent which has both of a functional group and an unsaturated double bond reacting with said resin. CONSTITUTION:An adhesive, which is based on an epoxy resin and a curing agent thereof and compounded with a monomer or oligomer having both of a functional group and an ethylenic unsaturated double bond reacting with the epoxy resin in an amount of 2-30pts.wt. per 100pts.wt. of the epoxy resin, is applied to a metal plate to be cured. Then, rubber paint having an ethylenic unsaturated double bond or a composition prepared by adding org. peroxide to said rubber paint is applied to said metal plate and vulcanization is performed to prepare a rubber coated metal plate. The vulcanization of the rubber paint can be performed by the irradiation with electron beam. When crosslinking is performed by the irradiation with electron beam, electron beam may be applied in a dose of 2-30Mrad. When vulcanization is performed by heating, vulcanization can be easily performed in the state of the metal plate like press vulcanization and heating may be performed at temp. equal to or more than the pyrolysis temp. of org. peroxide.

Title: Personal communication system
Inventor: ENDO TAKAHIRO
IPC: H04M3/42
Filed: 1991-07-10
Abstract: PURPOSE:To secure a next best measure such as the cancellation of a calling state and deputy response by other person in accordance with the intention of a caller when a person designated for the receiving of a confidential communication. CONSTITUTION:When a caller intends to process a communication as a confidential receiving call based on assigned number information, a receiving call indication S9 is displayed by a character message. Depressing a transfer key S18, an absence notification key S19, and a deputy response key S20 while not inputting an PID, activates S21 to S23 modes, respectively. Performing the PID input while not operating the S18 to S20 keys also activates an absence notification mode S22 or a disconnection processing after a lapse of prescribed period of time. When the PID input of an S17 key is confirmed, a control part checks an error (S25) and when the prescribed period of time passes with a correct input not conducted, the absence notification mode is activated. In the coincidence with the registered PID as the result of a check, a deputy response mode #lS29 is activated. When the designated person is absent at the time of call receiving indication, the other other person can respond or the alterntive response, transfer and absence notification of the designated person can be enabled.

Abstract: PURPOSE: To stably prepare high-quality acetylene black, by lowering thermal decomposition temperature for acetylene by admixture with a specified exothermically decomposable hydrocarbon and isothermally decomposing the acetylene at a constant temperature ranging from 1,700°C to 2,400°C.  
     CONSTITUTION: In the preparation of acetylene black by exothermic decomposition, an exothermically decomposable hydrocarbon (e.g., an unsaturated hydrocarbon such as benzene or ethylene) is preheated correspondingly to a naturally radiated heat from a reactor so that an apparent theoretical temperature for said decomposition is 1,700W2,400°C, and supplied (or acetylene may be preheated). The acetylene gas shall be supplied to the reactor at a linear velocity of 10W45m/sec. Althrough the theorecital flame temperature for the thermal decomposition of acetylene is about 2,500°C, it is preferable to decompose acetylene at a temperature of 1,700W 2,400°C in order to obtain a high-quality acetylene black. Efficient decomposition is effected at a low temperature, by adding a hydrocarbon under said conditions.
