Abstract: PURPOSE:To eliminate a sense of incongruity onto its own image displayed on a display device by displaying its own image displayed on a display device of its own equipment after being picked up by a television camera as if it were observed in a mirror. CONSTITUTION:When an off-hook signal is transferred from a hook switch 4 to an operation control section 2 in the case of a caller side, the control section 2 drives all devices and since transmission code data of a transmission video signal processing section 6 gives a command to be outputted to a reception video signal processing section 8 to a display changeover section 9 simultaneously its own image picked up by a television camera 7 is displayed on a CRT 10. When dialing is implemented, it is detected by the operation control section 2, calling is implemented and an audio signal and a video signal are sent to a destination and the audio and the video signal from the destination are received. In this case, the control section 2 gives a command of sending the destination video signal received by the line control section 3 to be outputted to a processing section 8 to a changeover section 9, the image of the destination is displayed on a CRT 10.

IPC: H04N5/278
Filed: 1991-05-24
Abstract: PURPOSE:To improve the accuracy of size indication between two points of an object which is displayed on a display section or recorded onto a recording medium together with an object image and reproduced on a screen of a TV monitor or the like by detecting an edge of the object desired by a photographer for the measurement in the electronic still camera and using the edge as both ends of the size. CONSTITUTION:An edge of an object image fetched by an image pickup system means is detected by an edge detection section 9. A control section 10 calculates the size by using a size calculation section 10a based on zoom information at focusing, lens position information and recognized edge information. Then a character pattern of the size to be calculated is inserted into an object image by a character generator 14. When the edge of the object cannot be recognized, a measured point input section 11 selects a measured point. An object image whose size is indicated is recorded on a video floppy 15.

Filed: 1978-12-04
Abstract: PURPOSE:To secure an easy correction for both the oscillation frequency and the temperature characteristics for the tuning fork type oscillator using the combination of two different modes by providing the weights at several areas of the oscillator. CONSTITUTION:The silver is evaporated to combined tuning fork type crystal oscillator 5 with installation of weights 8 and 9. Oscillator 5 features resonance frequency Fof and Tof due to the flection and twist modes respectively.

In this connection weight 9 is provided at the fork position of the tuning fork. The fork part touches the node of the resonance, no effect is given to the oscillation displacement to ensure betterment of the temperature characteristics. This, however, causes inevitably some change of the resonance frequency. And to correct this change, weight 8 is provided at the tip part of the oscillator.

Abstract: PURPOSE:To reduce the effect of axial hole burning by dispersing light intensity distribution concentrated to a phase discontinuous section to phase discontinuous sections in a plurality of optimized quantities at separate positions. CONSTITUTION:The title laser has an N-type InP substrate 6 to which a diffraction grating 7 is formed, an undoped GaInAsP optical waveguide layer 8 shaped to a mesa-striped shape, an active layer 9, a P-type InP clad layer 10 and a P-type GaInAsP ohmic contact layer 11 and a P-type InP layer 12, an N-type InP layer 13, and an undoped GaInAsP cap layer 14 formed on both sides of the mesa stripe. A phase discontinuous section in the diffraction grating 7 is shaped near a reflecting edge face at every size such as 30mum and 50mum from the central section of a resonator. Consequently, light intensity distribution concentrated to one phase discontinuous section is dispersed to phase discontinuous sections in a plurality of, optimized quantities at separate positions, and the distribution of the light intensity can be flattened. Accordingly, a refractive index in a section having large light intensity is reduced, thus minimizing the effect of axial hole burning.

CONSTITUTION:In an ignition system in which sparks are generated in a spark plug 28 in each engine cylinder in association with an ignition signal issued from a control circuit 20, through an ignitor 26 and a distributor 14, the control circuit 20 changes the compensating amount of an ignition timing in the direction of spark retardation when the presence of knocking is found in view of the output of a knocking sensor 12, but in the direction of spark advance when no presence of knocking is found. In this arrangement, the speed of variation in the compensating amount of the spark ignition in the direction of spark advance is controlled to be changed in accordance with the compensating amount of the ignition timing toward the spark retardation side. Thereby, in case of no presence of knocking, upon the spark advance being made, an optimum speed of spark advance may be obtained.

Filed: 1995-05-24
Abstract: PURPOSE: To ensure position accuracy between a lens optical axis and a camera mount face and to improve the yield at painting by providing a projection to a contact face of a front panel with a main body opposite to the lens arrangement side of the panel. CONSTITUTION: A video camera 10 is made up of a main body consisting of an upper case 2 and a chassis 3 or the like and a front panel 11 having a lens. The front panel 11 is fixed to the chassis 3 by two threads penetrating through thread holes 12a, 121b. The precision of the lens optical axis provided to the front panel 11 with respect to the camera main body depends on the precision of a contact face of the front panel 11 with the chassis 3. Thus, a circular projection is provided to only a part with the thread holes 12a, 121b among the contact face with the main body in the front panel 11 so as to be made independent of other contact face 14 thereby realizing high precision. The painting is inhibited for the face to keep the precision but the face easily prevents intrusion of paint because of its step difference.
