Title: Hardening and tempering method for large-diameter wire by direct electric heating
Inventor: SAKATA SHINJI
IPC: C21D9/62
Filed: 1986-02-27
Abstract: PURPOSE:To easily harden and temper a large diameter wire with high quality and low energy consumption by directly electrically heating the traveling large diameter wire between inlet and outlet side electrodes and quickly cooling the wire with coolers provided before and behind the outlet side electrode. CONSTITUTION:The large diameter wire W subjected to a pretreatment is run in the state of loading tension thereto between an un-coiling stand 1 and a coiling stand 4. Electrodes R1, R2, R3 on the inlet side, intermediate and outlet side are disposed on the feed passage for the above-mentioned wire W and the wire is directly electrically heated by a power source E. The cooler J1 is disposed in the prescribed position behind the outlet side electrode R3 to quickly cool the wire W heated to 870-1,000 deg.C surface temp. to <=100 deg.C. The wire W is thereby hardened. The pressurizing force of the above-mentioned outlet side electrode R3 on the wire W is made settable to the force equal to or larger than the pressurizing force of the inlet side electrode R1, Further the surface temp. of the wire W past the outlet side electrode R3 is increased to the prescribed tempering temp. and thereafter the wire is quickly cooled by the cooler J2. The above-mentioned large diameter wire W is thereby hardened and tempered without spark flaws while the high roundness is maintained.

Title: Technique for preventing corrosive metal material in inorganic cured product from rust
Inventor: BABA AKIO
IPC: C04B28/04
Filed: 1991-02-13
Abstract: PURPOSE:To prevent a corrosive metal material in an inorganic cured article and improve durability by applying a mortar composition in which a porous aggregate specified in grain size, bulk density and water absorption are blended to the surface of an inorganic cured article. CONSTITUTION:A mortar composition obtained by blending porous aggregates having 5-0.06mm grain size, 1.5-0.1 bulk specific gravity and 500-15wt.% water absorption is applied to the surface of inorganic cured article such as cement mortar to be repaired or modified in which corrosive metal material such as steel is embedded. Thereby water permeability and water absorption of the corrosive metal material are reduced and the moisture permeability thereof is enhanced and rust-proofing effects can be provided to the metal material. Furthermore, a rust preventive or alkali metal salt may be built in the porous aggregate. Grain size of the aggregate is kept in the above-mentioned range in consideration of workability of trowlling. When bulk specific gravity is >=1.5 or water absorption is <=15wt.%, impregnating and absorbing ability of the rust proofing agent is low and moisture permeability of mortar is lowered. When bulk specific gravity is <=0.1 or water absorption is >=500wt.5, strength of the mortar is lowered and water permeability and water absorption is increased.

IPC: H04W36/08
Filed: 1978-04-08
Abstract: PURPOSE:To prevent a mobile station from taking a specific word or a noise for a normal control signal from a base station, by discriminating the regularity of the fixed code of the control signal. CONSTITUTION:On receiving start code 11 in channel swtiching command signal 10 transmitted from the base station, the mobile facility in a call state discriminates whether it is a start code or not. When it is identified as the start signal, the regualrity of the split phase signal of signal-kind discriminative code 12 is discriminated. Then, when it is discriminated that it has the regularity, a channel is disconnected and the mobile facility receives channel assignment code 13 and switches the its own channels according to the assignment channel. When it is discriminated the split phase signal is irregular, on the other hand, it is not regarded as the channel switching command signal and the channel is not changed over, thereby maintaining the channel state.

Abstract: PURPOSE:To reduce the power consumption by providing a heat insulating layer on the outer peripheral surface of a supporting roller, and forming plural ribbon-shaped heater films extending in the axial direction of the supporting roller, on the outer peripheral surface of the heat insulating layer. CONSTITUTION:A heat roller 1 is rotated in the direction as indicated with an arrow A by a driving motor which is not shown in the figure, and simultaneously, a backup roller 6 is rotated in the direction as indicated with an arrow B. In this state, at the time of a fixing operation, recording paper 7 loaded with a non-fixation toner is inserted into a fixing nip part of said heat roller 1 and backup roller 6. On the other hand, as for a heater film 4 formed separately, power is supplied successively and it is heated gradually, because a sliding electrode 9 contacts a heater electrode 8 successively immediately before said paper rotates and enters into the fixing nip part. The resistance of the heater film 4 becomes high as a temperature rises, and when it is driven by a prescribed potential, a current value decreases. Accordingly, by a potential difference across the resistance inserted in series into this side of the heater electrode 8, the temperature of the heater film 4 can be detected. An electrode control part 10 controls the power supply to the heater film 4 in accordance with this detected temperature, and supplies the power until the temperature becomes a set temperature.
