IPC: B63H25/04
Filed: 1980-11-14
Abstract: PURPOSE: To improve steering performance when a ship is at low speed by installing a thrust control mechanism which increases thrust of a propeller.  
     CONSTITUTION: When steering is applied during slow speed navigation AND circuit 25 gives high level signals as output, because both a timer 16 and a comparator 24 generate high level signals as output, and a selector switch 17 is accordingly tumbled toward output terminal. As a result, blade angle setting  signals 27 are increased in a magnification unit 21, while growing up to increased blade angle setting signals 27', and the signals are fed into a discriminating unit 18, so that signals 22 are transmitted to a blade angle control driving  device 7, until the blade angle has been increased, consequently the blade angle  of the propeller is increased, together with the thrust. Thus, when the thrust is  increased, generated water current is increased, thus steering effect shall be  enhanced.

Filed: 1999-06-08
Abstract: PROBLEM TO BE SOLVED: To improve the luminescent performances, stability, and durability by forming an europium phenanthroline complex dispersion ORMOSIL composite material treated with hexamethyldisilazane. SOLUTION: The reaction of a composite material prepared by dispersing a europium phenanthroline complex and an organic dye such as Rhodamine in an inorganic/organic matrix such as an ORMOSIL prepared by a wet sol-gel method is allowed to proceed in an alcohol solution of hexamethyldisilazane or its vapor to convert the silanol groups on the external surface or internal surface of the composite material into trimethylsiloxane groups to improve the stability of the composite material against a water vapor or a solvent. Further, the hydrophobicity treatment effects a decrease in the silanol group concentration, effects a decrease in a rate of the radiationless transition ascribable to the OH group stretching vibration casing the quenching of a rare earth complex and an organic dye molecule, and therefore effects an increase in the luminescent intensity of the composite material.

Title: Automatic settling device for unfinished product
Inventor: KURUTSU DEIIJINGU
IPC: B24B41/06
Filed: 1988-06-28
Abstract: PURPOSE: To attain exact automatic adjustment of a rotating unfinished product by sending impact impulse to a chuck when a work spindle rotates slowly, that is, each time a so-called high-point passes, and minimizing a rotational error of the unfinished product in the chuck. CONSTITUTION: When a work spindle 1 is rotated slowly in weakened and initialized tightening force of a chuck 4, continuous measurement is made based on the value and angle of the rotational error of an unfinished product 12 by a measuring device 11 and inputted into a controller. When the high-point of the unfinished product 12 passes through an impact device, the impact device functions, and acts on the chuck 4 radially. By moving the magnet coils 13, 14 of the shock device in the axial direction of an iron core 15, the impetus of the iron core is changed, and the impact energy generated by a hammer 16 is changed. This correction process is repeated until the rotational error is expected to reach a minimum. If the controller detects that correction has been conducted too much, the impact impulse is reduced.

Title: Method for controlling automatic transmission
Inventor: HENNEKEN MARKUS
IPC: F16H59/08
Filed: 1999-06-08
Abstract: PROBLEM TO BE SOLVED: To strictly correspond to an external running condition in a winter operating mode by detecting a slip or an ABS braking, setting a low friction value running condition, determining a counter via an ABS or a slip evaluation function and actuating the winter operating mode when a counting condition exceeds a limit value. SOLUTION: When a slip or an ABS braking is detected, a low friction value running condition is set. An ABS braking running condition is displayed by an ABS control unit 13 of an electric transmission control device 4. At an ABS braking, a counter is determined by a present acceleration of a vehicle or an input amount 15 equivalent to the present acceleration through an ABS evaluating function, and when generating a slip, the counter is determined by a difference between a target acceleration of the vehicle and the present acceleration or the input amount 15 equivalent to the difference through a slip evaluation function. When a counting condition exceeds a limit value, a winter operating mode is actuated by an electric transmission control device 4. Accordingly, a quick shift to the winter operating mode can be carried out at the generation of slip.
