Title: Magnetic levitation runner
Inventor: NAMIKATA TOSHIO
IPC: B60L13/04
Filed: 1994-03-23
Abstract: PURPOSE:To improve controllability of a magnetic levitation runner in which a composite magnet obtained by vertically superposing a permanent magnet and an electromagnet is applied. CONSTITUTION:A composite magnet 1 has an electromagnet 2, a pair of permanent magnets 3a, 3b and a pair of iron pieces 4a, 4b. The piece 4a performs a role of making a magnetic field of the magnet 3a substantially uniform between the piece 4a and a magnetic rail 21. Thus, even when the field of the magnet 3a and the field of the magnet 2 are superposed, a uniform magnetic field is generated. Of course, a magnetic field between the other piece 4b and the rail 21 can be similar except that a direction of a magnetic flux becomes reverse. Thus, a magnetic force of the magnet 1 can be easily balanced with a weight of a vehicle 25, and the vehicle 25 can be stably levitated to improve its controllability.

Title: Polarization separating element
Inventor: SHIRASAKI MASATAKA
IPC: G02B6/34
Filed: 1981-04-07
Abstract: PURPOSE:To obtain a low price polarization separating element with small size and light weight and small transmission loss, without lens, by inserting an optical film having polarization separating characteristics between bonding tilt end planes of two optical waveguide plates. CONSTITUTION:Opposing end planes of optical waveguide plates 21 and 22 such as glass are formed into a tilt end plane shaped and polished vertically on the respective upper plane and with an angle in the range of 40-50 deg. to the center axis of the plates 21 and 22. A dielectric multilayered film 23 having a polarization function is inserted between the tilt planes and bonded. Thus, a light propagating in the plate 21 is separated into a reflection polarization S shown in two dot chain lines and polarization light P transmitting in the film 23 as shown in three-dot chain lins at the film 23. Thus, optical circuit components for optical isolators and optical switches can be constituted with a small size by using the polarization separating element with less transmission loss and small size.

Title: Preventing circuit for damping of alternating current motor controlling system
Inventor: YANASE TAKAO
IPC: H02P21/22
Filed: 1980-04-22
Abstract: PURPOSE:To obtain a sufficient damping effect regardless of variable speed and a power-factor by a method wherein signals representing intermediate circuit voltage are divided by signals representing the magnitude of the output voltage of a converter, and overlapped to output frequency command signals. CONSTITUTION:An AC motor 4 is driven through a converter 2, an inverter 3 and a smoothing reactor 5 wired to a power source 1. A divider 14 is mounted, the input signals of a phase shifter 6 representing the output voltage of the converter 2 are divided by the speed setting signals of a setter 13 representing inverter frequency, the output is added to the speed setting signals through a linearizing circuit 15 and a differentiation circut 16, and the frequency of the inverter 3 is controlled through a voltage/frequency converter 12. Thus, when an angle of a power-factor increases due to the disturbance of torque, the primary current frequency of the motor is augmented, and a circuit functions so as to prevent the increase of the angle of the power-factor. Consequently, the optimum amount of compensation is obtained, and damping can be prevented.

Title: Magnetic recording medium
Inventor: SHIMOZAWA TORU
IPC: C09D7/12
Filed: 1985-03-19
Abstract: PURPOSE:To reduce dropouts in repeated traveling by providing a magnetic recording layer having high electric resistance, forming the binder of a backcoat layer with a radiation-curing resin and obtaining the low-resistance backcoat layer. CONSTITUTION:Since barium ferrite itself has a high electric resistance of >=10<16>OMEGA/cm<2> and hence the resistance of a magnetic recording medium is >=10<10>OMEGA/cm, the recording medium is easily covered with dust by electrification and dropouts are easily generated. However, by adjusting the resistance of the backcoat layer to <=10<10>OMEGA/cm<2>, dust is hardly deposited on the magnetic recording layer having >=10<10>OMEGA/cm<2>. Accordingly, dropouts are remarkably reduced, a cinching phenomenon is eliminated and stickiness is also eliminated. Consequently, when a radiation-curing binder is used, dropouts can be prevented, since rear type transfer is not carried out.

IPC: G11B5/708
Filed: 1985-03-20
Abstract: PURPOSE:To control the exhaustion of a lubricant due to the sliding of a magnetic head and to obtain the titled magnetic recording medium having excellent durability by mixing sulfur into the surface layer part of the magnetic film and further furnishing a lubricating layer. CONSTITUTION:Sulfur vapor is mixed into the vapor of a magnetic body at the last stage of formation of a magnetic film by vapor deposition and the magnetic body and the sulfur are simultaneously vapor-deposited to mix the sulfur into the surface layer part of the magnetic film. A lubricating layer is then formed on the surface layer part. Since the metallic salt of a >=10C straight-chain fatty acid having >=100 deg.C m.p. and hence excellent heat resistance is used, the coated film of the lubricant is not destroyed for a long period even when the film is heated by the sliding-contact with a magnetic head. Consequently, an excellent lubricating effect can be exhibited for a long period. Since the magnetic characteristic deteriorates to some extent at the part mixed with sulfur, the thickness of the surface layer part to be mixed with sulfur is regulated to <=500Angstrom  and the effect on the magnetic characteristic is controlled to a minimum.

Title: Composite key telephone set
Inventor: SASAKI HIROMASA
IPC: H04Q3/58
Filed: 1985-03-20
Abstract: PURPOSE:To attain direct reply to an incoming call from a specific line by controlling the incoming display to a specific single telephone set so as to give it to an incoming call only for a specific external line. CONSTITUTION:When an incoming call comes to a line 4, a central control section 7 recognizes the incoming call and sends a signal to a key telephone set control section 8. Thus, the key telephone set control section 8 sends the data signal to a key telephone set 2 to display the incoming call by means of light such as a lamp. On the other hand, a call signal of a line is sent directly or a signal from a central control section 7 activates a ring tone signal generating section 9 and sends a ring tone to a single telephone set 3. When a prescribed time is elapsed after the detection of the incoming call, the signal from the central control section 7 is used to apply incoming display by light on the key telephone set 2 and a call tone. Thus, the incoming call to a specific line is subject to incoming display by sound by the specific single telephone set and replied directly without holding or transfer to the incoming call.
