Title: Variable optical face, variable optical face unit, optical scanning system and condensing point position-movable optical system
Inventor: SAKATA MINORU
IPC: G02B17/00
Filed: 1994-05-10
Abstract: PURPOSE:To obtain a movable optical face which is low in driving voltage and high in degree of freedom in deformation by deforming this optical face by a strain inducing layer. CONSTITUTION:All of a substrate 13, the strain inducing layer 17 and the optical face 14 have a flat plate shape and the optical face 14 has just the function as a mere plane mirror when the voltage is not impressed between both electrodes 16, but a transverse direction strain is generated in the strain inducing layer 17 when the voltage is impressed between both electrodes 16 and, therefore, the substrate 13 is deformed and consequently optical face 14 is deformed. For example, the substrate 13 is, therefore, buckled and curved into an arc surface shape when the shrinking transverse strain is generated in the strain inducing layer 17 or the substrate 13 is bulged and is again curved into an arc surface shape when the elongating transverse strain is generated in the strain inducing layer 17. The optical face 14 acts as a concave mirror to condense the incident collimating light r on the optical face 14 when the optical face 14 retracts to have a concave surface shape in such a manner. Conversely, the optical face 14 acts as a convex mirror to divert the incident collimating light r on the optical face 14 when the optical face 14 is bulged.

Filed: 1987-05-19
Abstract: PURPOSE:To hold a film in a condition where a sufficient optical path correcting function is provided and the film is prevented from being damaged, by dipping the film in a low-viscosity liquid having a refractive index which is close to that of the film. CONSTITUTION:A lipophilic liquid whose refractive index is close to that of color film and which is low in volatility and extremely low in viscosity at the normal temperature and pressure, such as trichloroethane 18, is used independently or in the form of a mixture in which the liquid is mixed with plural other liquids as the liquid to be used to cover the uneven surface part 17 of the color film 15. Since the liquid is so extremely low in viscosity that the liquid can be wiped off easily and so low in volatility that it does not volatilizes while it is used in addition to its lipophilic property, the liquid completely enters into minute depressed parts without space. Therefore, an easily handled film holding method which is provided with a sufficient optical path correcting function can be realized.

Abstract: PURPOSE:To enable to operate a marine engine with the prescribed load by controlling the blade angle of a variable pitch propeller based on the deviation of the suction pressure signal of an engine. CONSTITUTION:The deviation between a set rack signal determined by a function generator 13 with the instruction from a blade angle instruction handle 02  and the actual rack signal is calculated by an adder and subtractor unit 16', is  fed to a PI controller 17, is calculated through a coefficient unit 19, a switch relay 20 and an integrator 21, is then outputted through an adder 22 and becomes  a blade angle control signal by an adder and subtractor 07' through a switch  relay 19. In this case, the deviation between a suction pressure signal and the  actual rack signal is inputted through a limiter 15 to an adder and subtractor  07'. Since a primary delay circuit 23 has a slight delay due to the relation operated through a blade angle operating system and an engine system with the  actual rack signal at the time of operating the handle, it can prevent the production of a quasi- signal which is temporarily outputted as the actual rack signal  and the set rack signal.
