Title: Manufacture of magnetic recording material
Inventor: KATSURAGAWA TADAO
IPC: G11B5/845
Filed: 1982-06-08
Abstract: PURPOSE:To prevent an error from being produced, by applying magnetic paint on a nonmagnetic support and applying main magnetic force of lines of an oriented magnetic field from both sides of the running magnetic layer in the direction of running with a specific complementary angle while the paint is still wet, for uniformizing a reproduced output of the entire circumference of a magnetic disc. CONSTITUTION:A magnetic field is applied on the support 1 with orientation magnets 4, 4' from both sides of a magnetic recording material 3 provided with an undried magnetic substance layer 2. Most magnetic force of lines of the oriented magnetic field has a complementary angle theta (0<theta<90 deg.) in the direction of running of the recording material 3. Thus, the orientation of ferromagnetic fine powder of the magnetic layer 2 in the direction of running is corrected at its application, the reproduced output over the entire circumference of the disc is uniformized, the modulation (expressed in Equation, where A is an average output about 2,000 of magnetic flux inversion including the maximum output around one cycle of the track, and B is the average output including the minimum output) is minimized to increase the reproduced output for uniformizing. The support is punched to manufacture a magnetic flexible disc of high quality with good yield.

Title: System stabilizing method
Inventor: SHIMADA RYUICHI
IPC: H02J3/16
Filed: 1991-04-03
Abstract: PURPOSE:To realize stable power supply by detecting a change in the internal phase angle of a generator from the rotor phase of the generator and voltage phase on a system side and controlling the internal phase angle of a synchronous phase modifier by means of a high-speed phase shifter so that excessive power can be absorbed by the synchronous phase modifier. CONSTITUTION:An RC internal phase angle change detecting means 7 detects the phase difference between the inside of an RC and system and supplies the detected phase difference to a firing angle control means 8 as  deltaR. On the other hand, a generator internal phase angle change detecting means 9 supplies the variation  deltaC of an internal phase angle when a system accident occurs to the control means 8. The  deltaC is the phase angle of a generator corresponding to the power which becomes excessive when one transmission line circuit is cut off by the accident. Then the control means 8 finds the power to be supplied to the RC from the  deltaC and  deltaR and controls the firing angle of a generator by outputting the control angle alpha corresponding to the value to a phase shifter. Therefore, the fluctuation of the system can be suppressed when the system accident occurs.

Title: Cipher communication method
Inventor: SHINTANI YASUMASA
IPC: H04N1/44
Filed: 1983-06-01
Abstract: PURPOSE:To automatically perform communication with a communication procedure control signal which is not ciphered irrespectively of whether or not a receiver is equipped with a cipher decoder, by including information indicating that whether or not the receiver is equipped with a cipher decoding device in the communication procedure control signal, and performing ciphered communication only when the receiver is provided with the decoder. CONSTITUTION:In response to a call from a transmitter 1, the circuit between the transmitter and a receiver 2 is connected and the transmitting function and receiving function of the transmitter 1, and receiver 2 are mutually confirmed. Then a control signal outputted from a communication controlling circuit 5 is inputted into the signal input terminal 22 of the receiver 2 from a signal output terminal 23 through the circuit without being ciphered and further inputted into a communication controlling circuit 13 without passing through a decoding circuit 16. A receiving function discriminating signal including information indicating that whether the receiver 2 is equipped with a cipher decoding function or not, is transmitted from the communication controlling circuit 13 to the transmitter 1. Upon receiving the discriminating signal, the communication controlling circuit 5 of the transmitter 1 sends a mode setting instruction signal including information indicating that ciphered transmission is performed as the response. When the information indicating that ciphered transmission is performed is included in the mode setting instruction signal, the communication controlling circuit 13 of the receiver 2 controls a multiplexer 15 so as to select the output of the decoding circuit 16.

IPC: G01N33/20
Filed: 1988-04-22
Abstract: PURPOSE:To easily measure the degree of deterioration of ferrite-based heat- resisting steel with time by using the close correlation between the deterioration degree and an experimental expression showing the relation among the absolute temperature, elapsed time, and property value, e.g. particle side of deposited carbide.

Further, a relational expression has close correlation with the deterioration degree. For the purpose, a forcible acceleration test of a test piece is conducted so that the temperature and time are parameters, and a deterioration degree evaluation reference curve showing the relation with a property value such as gain size sown by said grain size is found previously. This used to easily measure the deterioration degree of the object member.

Abstract: PURPOSE:To reduce the possibility of the breaking of an optical fiber due to external force resulting from the curvature, etc., of a core wire fiber, by engaging a coiled body of a thin wire with the protective sheath of the optical fiber at its fixed end and by fixing it with resin. CONSTITUTION:The terminal part of a core wire fiber 3 coupled with an optical connector is wound with a thin wire 6 made of metal or provided with an inserted spiral thin wire, and resin is applied over the part to anchoring to an inner ferrule. The thin wire and resin exposed out are covered with a thermally contracting tube or cap 5. Thus, the resin is applied by using the thin wire as an assistant material to increase adhesive sterngth between the resin and nylon, and fibers near the terminal of the nylon are applied with little stress in bending the core wire fiber. Therefore, the breakdown of the fibers is prevented. The tip of the core wire fiber 8 is made spherical and the protective sheath of the fiber 8 opposed to a photoconductor element 13 is anchored similarly to prevent the fibers from breaking.

Abstract: PURPOSE:To improve the thermal deterioration of a polymer film occuring in a calender treatment, by subjecting a polymer film to the calender treatment then subjecting the surface of the polymer film which is not applied with the calender treatment to a cooling treatment. CONSTITUTION:A polymer film of polyester, PE, polyimide, etc. is passed between rolls and is thereby hot-rolled, whereafter a calender treatment is applied on one surface thereof.

Ferromagnetic metal of iron, cobalt, nickel or the like is further stuck on the calendered surface of the polymer film by a diagonal vapor deposition method or ion plating method at the prescribed incident angle maintained to the normal of said film, whereby a magnetic material layer is formed. If necessary, a protective layer consisting of metal, metallic oxide, or polymer material is formed on the magnetic material layer to provide lubricity and corrosion resistance.
