Abstract: PROBLEM TO BE SOLVED: To provide a reception data quantity control method and a device by which a reception terminal such as an Internet video phone can control a reception data quantity from a transmission terminal and efficient real time data communication is attained without interrupted sound and disturbance in an image. SOLUTION: When a reception terminal recognizes that fluctuation in a packet loss or a packet exceeds a prescribed value in the case of real time data communication, the reception terminal transmits a data quantity change request packet to a transmission terminal on the opportunity of discrimination by an Internet telephone software itself or discrimination by a user. When the transmission terminal receives it, the transmission terminal discriminates the real time data transmission method by which the revision of the transmission data quality can be made, and when the revision is possible, the transmission terminal transmits the packet by the real time data transmission method. When the revision is unreasonable, the transmission terminal transmits a data quantity revision reject packet to the reception terminal without changing the transmission data quantity.  When the reception terminal receives the packet, the reception terminal terminates the processing to recognize the reception state or the user operation.

Title: Evaluating system for voltage detector
Inventor: NAKAMURA TAKUYA
IPC: G02F1/03
Filed: 1987-06-10
Abstract: PURPOSE:To enable the performance of a voltage detector for the ultrahigh speed voltage change of an object to be measured to be evaluated with a high reliability by making pulsed light with a pulse width shorter than several hundred f.sec incident upon an electrooptical material. CONSTITUTION:Pulsed light with a pulse width shorter than several hundred f.sec is incident upon an electro-optical material 62 in a condition wherein it is applied with no voltage from a f.sec laser 2 in parallel to the light path of incident light from a light source 53. As a result, an electromagnetic wave EM with the pulse width shorter than several hundred f.sec is transmitted through the material 62 toward a reflecting mirror 65 and the refractive index of the material 62 changes only for a time shorter than several hundred f.sec. Due to refractive index change thus generated, the polarization components of the incident light from the light source 53 passing a polarizer 54 and of emitted light to a streak camera 7 change and only the emitted light with a prescribed polarization component is extracted by an analyzer 57 to be incident upon the camera 7. Thus, since the emitted light from the light source 53 proceeds pursuant to the refractive index change and an interaction is elongated, polarization component change is increased and the performance of a voltage detector 1 can be evaluated by the camera 7.
