Title: Magneto-optical disk reproduction device
Inventor: IZUMI HARUHIKO
IPC: G11B11/10
Filed: 1991-09-20
Abstract: PURPOSE:To prevent a baseline shift caused by a data pattern by providing a focus and track error signal detection system and a reproduction signal system separately and by letting reproduction signals to have a frequency band including a DC component in the device which reproduces already recorded information from a magneto-optical disk in that information is recorded by an edge recording method. CONSTITUTION:An error signal detection section 14 of an optical head 13 and a magneto-optical reproduction signal detection section 15 are provided separately. Having this arrangement, no interference exists between the reproducing signals from a magneto-optical reproduction detection section 15 and the error signals and there is no need for an error signal separation high pass filter. Thus, the band of the reproduction signals is extended to DC components. A slice level detecting circuit 16 generates a slice level and supplies it to a pulse generating circuit 17. The pulse generating circuit 17 compares the above mentioned slice level and the level of the reproduction signals and generates a reproduction pulse. The slice level detecting circuit 16 holds a middle value of the maximum and the minimum values of the reproduced and prescribed signals as the slice level prior to the data reproduction.

Title: Thrust unit starter with variable pitch propeller
Inventor: NAKAMURA KOJI
IPC: H02P1/16
Filed: 1984-11-19
Abstract: PURPOSE:To start without using a special starter by starting a thrust unit by a start motor having small capacity at starting time, and driving a drive motor when arriving at a rated speed. CONSTITUTION:When a controller 5 for driving a thrust unit 1 is operated, a controller 5 sets a magnet switch 7 to ON, and power is supplied to a start motor 4. Since a starting current flowed to the motor at starting time is much smaller than the starting current when starting by supplying a current to a drive motor, a power source is directly supplied to start without using a special starter. When a signal supplied from the motor 4 to the controller 5 represents the rated speed, the controller 5 sets a magnet switch 6 to ON to supply power to the motor 3.

Title: Bubble making method and machine therefor
Inventor: MITSUO KOJI
IPC: B01F3/04
Filed: 1984-11-19
Abstract: PURPOSE:To easily generate minute and uniform bubbles, by receiving inside direction feed materials at both sides in a bubble making cylinder in such a state that a bubble cutting jig is interposed or not and including and/or uniformizing bubbles from a foamable material between the feed materials. CONSTITUTION:When a valve 16 is opened and a foamable liquid is flowed into a quantitative tank 10, said liquid is flowed into a sedimentation tank 1 through a hose 11 to enter a bubble making cylinder 2. Said foamable liquid receives impact by the rotary action of a lower feed material 5' to be formed into bubbles which are, in turn, raised because the lower feed material 5' has upward feed force and cut by a bubble cutting jig 6. An upper feed material 5 has downward feed force and turbulent flow is generated between the feed materials 5, 5' to allow bubbles to be apt to be stagnant and bubbles are cut and uniformized by the action of the bubble cutting jig 6 to form uniform and minute bubbles. These bubbles are flowed into the sedimentation tank 1 and rise through said sedimentation tank 1 to fill said sedimentation tank 1 and are emitted from a bubble emitting pipe 8.

Inventor: HARAYAMA YUTAKA
IPC: B05D5/12
Filed: 1984-11-16
Abstract: PURPOSE:To array more smoothly magnetic powder in parallel with a substrate plane by providing annular permanent magnets near the top end of an injection nozzle for a magnetic paint and impressing the magnetic fields in parallel with the axial center to the magnetic powder. CONSTITUTION:Plural pieces of the annular permanent magnets 10 are disposed near the top end of the nozzle 5 for injecting the magnetic paint. The magnets 10 are so magnetized in the direction parallel with the axial center of the nozzle 5 so that both ends are of N and S poles. The magnets are also so disposed that the adjacent magnetic poles are of the same polarity. As a result, the magnetic flux is generated in the direction parallel with the axial center and the needle-like magnetic powder 9a is arrayed in parallel with the axial center, by which the entanglement is easily loosened and the powder 9a is thus more smoothly arrayed with respect to the substrate plane by the orientation treatment after coating.

Filed: 1984-11-21
Abstract: PURPOSE:To obtain a toner contg. most of a magnetic material uniformly dispersed into the inside of the toner by incorporating a colloidal silica treated with a silane coupling agent and, a magnetic material powder. CONSTITUTION:The colloidal silica treated with a silane coupling agent having a polar group is dispersed into a polymerizable monomer together with the magnetic material powder to allow the powder to adsorb the colloidal silica in a state of orienting the silica and thus to enhance the dispersibility of the magnetic material. The rise of viscosity due to addition of the colloidal silica contributes to prevention of deposition and localization of the magnetic material in the polymerizable monomer, thus permitting the obtained toner to contain most of the magnetic material to be uniformly dispersed in the inside of each toner particle.

Title: Automatic skid-preventing chain attaching/detaching device for car tire
Inventor: TOMIYAMA TOKU
IPC: B60C27/14
Filed: 1984-11-21
Abstract: PURPOSE:To enable attaching/detaching of skid-preventing chains from the inside of a car and to enhance durability of the chains by arranging a flexible gear, a supporting wire, and a skid-preventing chain connected to the supporting wire in such a manner that they cross both tire and rim and constituting the system so that the chain can be attached to or detached from the tire through revolution of the flexible gear. CONSTITUTION:When a car is to run on a ice-covered road, tire wheels are replaced with wheels equipped with this device. By pushing the power button at the driver's seat as necessary, a supporting lever 21 is shifted backward via operation of a solenoid. As a result, the lining 23 of a driving board 25 is brought into contact with a pulley 11, and the pulley 11 is rotated. With this, a worm gear 9 makes turning movement, while a flexible gear 5 moves, accompanying a supporting wire 3. Thus, a chain 15 connected to the supporting wire 3 is shifted from a non-operational position to the chain attaching position over a tread surface. This operation can be reversed by pushing a releasing button not illustrated here. With this constitution, the chain can be attached or detached from the driver's seat. In addition, since the chain is attached only when necessary, car's safety can be ensured, while durability of the chain can be enhanced.
