摘要:
A color cathode ray tube panel has a glass face portion including a substantially flat outer surface facing a viewer and an inner surface on which a phosphor screen is coated. The inner surface is concavely curved with a radius of curvature R.sub.x in a direction of a horizontal axis of the cathode ray tube, and the following conditions are satisfied: ##EQU1## where W.sub.h denotes a horizontal width of an effective area of picture in the face portion, L denotes an optimum viewing distance, n.sub.1 denotes a refractive index of the face portion, and t denotes a thickness of the face portion at its center.

An image display device has a front case provided with a phosphor screen on an inner surface thereof; a rear case facing the front case; a sealing portion with which the front case and the rear case are hermetically sealed so that an airtight chamber is formed between the inner surface of the front case and an inner surface of the rear case; and a cathode board including a cathode which is disposed within the airtight chamber and faces the phosphor screen and a wiring pattern for applying a voltage to the cathode. The the cathode board is held between the front case and the rear case by the sealing portion so that the cathode board is not in contact with the inner surface of the front case and the inner surface of the rear case.
摘要:
A data recording and reproducing apparatus which can easily perform the editing of audio and/or visual data even at the camera site. In the data recording and reproducing apparatus, a VTR portion and an MO disc portion are integrally constituted. Audio and/or visual data input from an outside apparatus is recorded on a video tape by the VTR portion, and further reproduced from the video tape and transferred to the MO disc device at a high speed and recorded. The user of the data recording and reproducing apparatus quickly finds the desired video image by actively utilizing the random access property of the MO disc device and sequentially inputs the same to the VTR device, records the same on the video tape, and performs the editing of the audio and/or visual data.

摘要:
Video data controllers and disk array units are connected with an independent input serial transmission line and an independent output serial transmission line. Data is serially transmitted between the video data controllers and the disk array units. Data of the video data controllers is sent with time slots assigned thereto. Data has a synchronous signal at the beginning thereof. The synchronous signal synchronizes with time slots. The synchronous signal is followed by commands/status and video data.
摘要:
A data recording apparatus which simultaneously records data to a plurality of radially divided recording areas of a disc recording medium by the CAV method, including a data dividing unit for dividing the input data into amounts of data proportional to the radial lengths of the plurality of recording areas and a plurality of data recording units for simultaneously recording the data to the corresponding recording areas at data recording rates proportional to the radial lengths of the recording areas; a data reproducing apparatus which reproduces data recorded by such a data recording apparatus including a plurality of data reproducing units, provided corresponding to the data recording areas, for simultaneously reproducing data from the recording areas, and a data rearranging unit for rearranging the data reproduced from the recording areas to the same order as the original input data; and a data recording/reproducing apparatus including such a data recording apparatus and data reproducing apparatus.
摘要:
A projection cathode ray tube (CRT) includes a multilayered interference film interposed between a face plate pane and luminescent material layer. This multilayered interference film is composed of alternately superimposed of high refractive index material layers and low refractive index material layers, and the number of layers to be superimposed is four or five. By using a multilayered interference film of only four or five layers, the interference layer is not subject to cracks or film separation occurring during heat processing, due to the difference in thermal expansion coefficients between high and low refractive index material. Further, there still remains enough layers to produce a display highly improved in brightness in the direction of the normal of the face plate pane of the CRT.

摘要:
Data indicative of a transfer mode of a transmission packet may be inserted into a payload portion contained in a serial digital transfer interface (SDTI) transmission packet. Also, data indicative of a timing mode of the transmission packet may be inserted into this payload portion. As the transfer mode, there may be provided a synchronous transfer mode and an isochronous transfer mode in addition to an asynchronous transfer mode. A timing mode may prescribe a timing mode in which a transmission packet may be transferred in synchronism with a field of a transmission frame. There may be provided a normal mode using a first field, an advanced mode using a second field and a dual mode using both fields. Depending upon the manner in which the timing mode is set, a system delay between the transmission and the reception can be minimized.
