Title: Magneto-optical element
Inventor: OKITSU ATSUSHI
IPC: G02F1/09
Filed: 1990-11-19
Abstract: PURPOSE:To obtain the magneto-optical element which is high in operating response speed, is large in contrast ratio, is simple in construction and inexpensive by sealing magnetic fluid into the part corresponding to the spacing of a yoke core by a light transmissive member, thereby forming the thin film of the magnetic fluid having the film thickness corresponding to the thickness size of the yoke core. CONSTITUTION:The magnetic field in a prescribed direction is generated in the spacing part 3 of the yoke core 2 when the coil 7 is energized. A magneto-optical effect is then generated in the magnetic fluid 5 and controls light transmission characteristics and, therefore, the on and off of light are controlled by on-off controlling the energization and de-energization of the coil 7. In addition, medium gradation light can be transmitted by regulating the current of the coil 7. The response speed of the on-off actions is extremely faster than the on-off actions of the conventional electrooptical elements and a high contrast ratio is assured. The correct resolution of the medium gradation, etc., is obtd. Further, the material cost of the fluid 5 which is a main driving material is extremely low and, therefore, the cost of production is reduced. Since the film thickness of the fluid 5 can be easily regulated, the production efficiency is extremely enhanced and since the winding part 4 of the core 2 projects from a substrate 1, the winding operation of the core is extremely facilitated.

Filed: 1991-11-01
Abstract: PURPOSE:To effectively increase the illuminance with use of two light sources by providing alternately a 1st incident surface group tilted in the prescribed direction so as to connect a 1st caustic curve to a prescribed position and a 2nd incident surface group tilted in the adverse direction so as to connect a 2nd caustic curve to another position on the surface of a light transmissive member having the light transmissivity and also to set all luminous fluxes sent from the light sources in parallel to each other. CONSTITUTION:The incident surface groups 9 and 10 tilted in the directions adverse to each other are formed on the surface of the the light transmissive members like the glass, the plastics, etc., having the light transmissivity, i.e., the cylindrical Fresnel lenses A and B. Both groups 9 and 10 have the caustic curves at the different positions in a space respectively. A double caustic curve cylindrical Fresnel lens 2 contains the 1st and 2nd incident surface groups 11 and 12 which are alternately synthesized in half cycle of the pitch of both groups 9 and 10. Then both groups 11 and 12 can freely select the optimum curved surfaces among the ridgelines 13 and the valley lines 14 so as to set the luminous fluxes sent from two light sources 3A and 3B in parallel to each other. In this case, the distances between both sources 3A and 3B and the center part 2a of the lens 2 are larger than the distances between the sources 3A and 3B and both end parts 2b of the lens 2. The luminous fluxes sent from the light sources FA and FB are all made incident on the 1st and 2nd incident surfaces 11 and 12 and horizontally set in parallel to each other after refraction and transmission.

Filed: 1987-12-11
Abstract: PURPOSE:To record a photographing image at a timing suitable for a recording medium by reading after resetting a timing signal generation means after exposure in case of recording on a floppy disk but reading immediately after the exposure in case of recording in a semiconductor memory. CONSTITUTION:In case of reading charges from an accumulating part 3 and recording on a floppy disk FD, a recorder 6 comes in recording-able state after the end of the transferring to the part 3, and the recorder 6 waits for that PG signals representing the reference of the rotation of the FD comes stabilized. When this PG signal is impressed to a PG circuit 22, an edge detection circuit 24 detects the rise of the positive PG signal. Thus a driving device 4 drives to read accumulated charges from the part 3 to record on the FD on a floppy driver 33. On the other hand, in case of recording in a semiconductor memory 34, the charges are read out immediately after the transferring of charges to the part 3 to achieve the recording in the semiconductor memory. In such a way, by varying the timing of read from the accumulation part of a solid-state image pickup element, the recording of a photographing image can be achieved at the timing suitable for a recording medium.

Filed: 1996-11-26
Abstract: PROBLEM TO BE SOLVED: To switch an antenna without lost in telemetry by generating a switch driving pulse for antenna change-over, which is synchronized with the frame sink code of telemetry. SOLUTION: An antenna switch drive circuit for generating the switch drive pulse for antenna change-over in synchronizing with a telemetry frame termination pulse is added to an antenna switch circuit.
