Title: Disk loading mechanism for freely detachable optical-disk driving gear
Inventor: BURATSUDO JIYONSON
IPC: G11B17/04
Filed: 1993-11-10
Abstract: PURPOSE: To make this unit compact by providing a positioning means connected with a magnetic bias means and a mounting means for moving the magnetic bias means from a retracted position to an opening position while being linked with the mounting means. CONSTITUTION: When a cartridge holder 10 is moved from a first position to a second position, the motion of the cartridge holder 10 is converted into the motion of a magnetic bias coil by a link mechanism so that the coil can be moved from a retracted position separated from a disk 7 to an operating position close to the surface of the disk 7. In this unit, the motion of the bias means is operated while being linked with the mounting of the disk so that the exact positioning of the magnetic bias means can be assured. Also, the height of this device in a vertical direction is extremely small so that the overall size of the disk driving device can be reduced.

Title: Tire air pressure detecting device
Inventor: TOMINAGA MOTONORI
IPC: B60C23/06
Filed: 1996-10-01
Abstract: PROBLEM TO BE SOLVED: To accurately detect sudden turning even when a dynamic load radius is different between inside and outside wheels, and improve detecting accuracy of a tire air pressure condition by performing an operation on a variation width in a prescribed time of an approximate value, and prohibiting detection of a tire air pressure condition when the variation width of the approximate value exceeds an upper limit value. SOLUTION: An operation is performed on a deviation between the angular velocity ratio of front wheels 1a and 1b and the angular velocity ratio of rear wheels 1c and 1d from angular velocity of four wheels, and a wheel speed deviation value is found, and when this deviation value is increased by a threshold value or more than its initial value, it is judged that tire air pressure is reduced in either of the wheels 1a and 1d, and when it is reduced by the threshold value or more than the initial value, it is judged that the tire air pressure is reduced in either of the wheels 1b and 1c. In this way, since actual lateral directional acceleration is obtained from a variation width of operational lateral directional acceleration, even when a dynamic load radius is different between the inner wheel side and the outer wheel side, sudden turning can be accurately detected.  Then, detection is prohibited at sudden turning time, and it is detected only at normal travel time.

Title: Ink adjustment device for lithographic press
Inventor: DEIBUITSUDO KINGUSUREI GOONTO
IPC: B41F31/00
Filed: 1989-10-31
Abstract: PURPOSE: To perform continuous printing using ink having stabilized degree of emulsification by forming a film of emulsion on the surface of rollers, breaking the emulsified ink down into an ink phase and an aqueous phase by exerting a pressure from a nip, displacing the aqueous phase to an aqueous phase collector by gas jets and removing the ink phase from the rollers after passing through the nip thereby removing excess water. CONSTITUTION: Emulsion ink is fed from a tank 1 through ducts 6, 8 to a duct defined by a blade 5 and a steel roller 3. The duct leaves an emulsion film on the surface of the steel roller 3 and the film is subjected to squeezing action of a nip between the rollers 3, 4. Consequently, the emulsion is broken down into aqueous phase and ink phase components at the nip. The aqueous phase is displaced away from the ink phase by blowing air jet to the nip trough a nozzle 10 and dropped, as droplets, into a drip tray 11 before being discharged to a collector 12. Ink containing reduced moisture passes through the nip between the rollers 3, 4 and removed from the roller 3 by means of a doctor blade 9 before being returned back to the tank 1.

Thus it is possible to realize the highly effective reactions of two types of fluid over a wide range of flow rates. Then the fine temperature control is attained with use of a burning device.
