Filed: 1999-04-01
Abstract: PROBLEM TO BE SOLVED: To provide a method for the production of a magnetic recording medium to obtain a magnetic tape which snows excellent travelling stability when the tape is carried at a fast rate in a system using a multitrack head to realize a high transfer rate and which does not deform or protrude when the tape is wound on a real to preserve data. SOLUTION: The magnetic recording medium has a magnetic layer formed on one surface of a supporting body and has a back layer containing carbon black, a material which generates heat by irradiation of laser light, and a binder on the other surface of the supporting body. In this medium, the back layer is processed by irradiation of laser beams. In this method, after the back layer is processed, the back layer is cleaned. The material which generates heat by the irradiation of laser light consists of an acicular metal powder having <=0.1 μm average minor axial length and/or spherical Fe3O4 powder having <=0.1 μm average particles size.

Title: Azimuth transducer
Inventor: KAKIZAKI YASUO
IPC: G01C17/36
Filed: 1979-07-25
Abstract: PURPOSE: To obtain a digital signal which has a prescribed relationship with an azimuth angle, by generating a pulse in a phase angle position corresponding to the azimuth angle and using the pulse to pick out and hold the clock count content of a counter.  
     CONSTITUTION: The output of a synchro transmitter 2 is supplied to a means 5 through a Scott-connected transformer 10 so that the output is changed into DC signals Vcosθ, Vsinθ corresponding to an azimuth angle θ. Both the DC signals are applied to a pulse generation means 6. A pulse pk of phase corresponding to the azimuth angle is produced by the means 6 from both the DC signals and reference signals Vcosωt, Vsinωt which have reference phases and are supplied from comparators 13a, 13b. Clock pulses of frequency integer times more than that of the reference signal Vsinωt are generated by a clock signal source 7 synchronously with the reference signal. The clock pulses counted by a counter 8. The count content of the counter is picked out into a holding means 9 by the pulse pk. As a result, a digital value having a prescribed relationship with the azimuth angle can be obtained independently of the type of a gyro 1.

Title: Exciter for electromagnetic clutch
Inventor: SAYOU KOUSAKU
IPC: F16D27/10
Filed: 1980-07-15
Abstract: PURPOSE: To enable the design of an electromagnetic coil of high coercive force, by enlarging a housing for the coil, and to improve magnetic performance, by using an auxiliary magnetic member.  
     CONSTITUTION: The outer flange 21c of the U-shaped main member 21 of a stator 20 is placed outside the outer flange 8a of a rotary input body 8 concentrically therewith to constitute a main magnetic circuit A. Since the lead wire takeout hole 21b of the main member 21 and the lead wire connections 16a, 16b of an electromagnetic coil 12 are opposed to the end of the outer flange 8a of the rotary input body 8 and placed in parallel with each other, a housing for the coil 12 can be greatly enlarged in comparison with conventional devices. For that reason, an electromagnetic clutch of higher transmitted torque capacity can be manufactured even if the dimensions of its members except for an exciter 11 are equal to those of the members of the conventional devices. Magnetic performance is improved further by fitting an annular auxiliary magnetic member 22 of L-shaped cross section in the main member 21.

Title: Folded leaf feeder
Inventor: YAMADA MASATOSHI
IPC: B65H83/00
Filed: 1982-06-04
Abstract: PURPOSE:To permit folded leaves to automatically drop straight into a pocket by sucking one by one folded leaves lifted by an levator with a suction roller and transferring automatically the leaves into the pocket for a leaf aligning machine while sucking them to the lower surface of a conveyer belt. CONSTITUTION:A laminate A of folded leaves is moved to an elevator 1 by the operation of a supply conveyer 2 and lifted by a carrier plate 11. When the uppermost portion of the laminate A approaches a suction roller 25, the suction roller 25 sucks one by one the folded leaves to mount them on a transfer device 4 in which a conveyer belt 34 circulates around a vacuum box 33. Respective holes 44 in the conveyer belt 34 communicate to a hole 43 in the vacuum box 33 on the lower side position to be evacuated so that the folded leaves sequentially sent from the suction roller 25 are sucked to the lower surface of the conveyer belt 34 to be sent to a pocket 3. Since the hole 44 does not communicate to the vacuum box 33 at an end of the outlet side of the conveyer belt 34, the folded leaves drop into the pocket 3.

Title: Compressed-gas-insulated switchgear
Inventor: MIWA IKUO
IPC: H01H33/59
Filed: 1989-04-18
Abstract: PURPOSE:To reduce disconnector surge voltage and to improve reliability of insulating performance by forming a sequence so that an earth switch may be closed in opening a disconnector or two disconnectors while a circuit breaker is in an open state. CONSTITUTION:A sequence is found so that earth switches 9 or 6 may be closed after the opening of a disconnector 7 or disconnectors 2 and 3 so that it or they may be closed and opened before the initial closing of either the disconnector 7 or disconnectors 2 and 3. On that account, after the opening of the disconnector 7 or disconnectors 3 and 3, the DC voltage remaining in a conduit between the disconnector 7 or disconnectors 2 and 3 and a circuit breaker 1 is discharged through the earth switch 9 or 6. Consequently, in opening either the disconnector 7 or disconnectors 2 and 3 no residual DC voltage is in the conduit between the circuit breaker 1 and the disconnector 7 or disconnectors 2 and 3 in the initial closing and the foreign material is dropped on the tank side which is insulatingly safe. Since there is no residual voltage, the disconnector surgevoltage generating in closing the disconnector is reduced.
