IPC: H04N5/64
Filed: 1993-05-17
Abstract: PURPOSE:To obtain a compact head-mounted type video display device capable of simply and properly correcting diopter without requiring a mechanical mechanics. CONSTITUTION:In a device provided with a two-dimensional display element 11, a prism 12, a half mirror 13, a concave mirror 14, an eyepiece, and a liquid crystal shutter and having a see-through function, liquid crystal lenses 19, 20 whose refractive indexes are changed by voltage control are used for the eyepiece and the liquid crytal shutter. The voltage of the lenses 19, 20 is controlled by a controller 51. When voltage is impressed to the lenses 19, 20, the refractive indexes of the lenses 19, 20 can be continuously changed in accordance with a voltage change. The power of the optical system can be changed and diopter can be corrected only by adjusting the voltage and the lenses 19, 20 can be substituted also for the liquid crystal shutter. Since it is unnecessary to move the element 11 or the lens body to correct the diopter while holding the see- through function, a mechanical device and an operation space are made unnecessary and device constitution can be made simple and extremely compact.

Title: High frequency signal switching circuit
Inventor: MAEDA TETSUHIRO
IPC: H04N5/44
Filed: 1982-07-01
Abstract: PURPOSE:To reduce considerably the leakage of a signal which leaks through a capacitive component to the other input terminal, by providing a switching transistor (TR) for flowing the leaked signal to the ground. CONSTITUTION:While a playback RF signal of VTR is applied to the 1st input terminal I2 and a received signal from an antenna is applied to the 2nd input terminal I2, the playback signal of VTR is led out to an output terminal O. When only the 1st power source B1 is turned on, TRs S1-S4 turn off the TRs S5-S8 turn on. Therefore, TRs T1 and T3 turn on and TRs T2 and T4 turn off to lead the VTR playback signal to the terminal O through a capacitor 5, the collector-emitter impedance parts of the TRs T1 and T3 during conduction, and an output capacitor 2. At this time, a signal appearing at the common emitter of the T1 and T2 is apt to leak to the other input terminal I2 through the interelectrode capacitance of the T2 and T4, but the cascade connection point of the T2 and T4 is grounded by the S7, so that the leakage is almost prevented.
