IPC: G11B20/12
Filed: 1993-12-03
Abstract: PURPOSE:To efficiently record and reproduce various attendant data and to efficiently use a data recording area by recording line designation data, which designates an arbitrary line of a picture signal, and a parameter related to encoding of the signal. CONSTITUTION:The signal of an arbitrary line of the video signal is extracted and is encoded in an arbitrary encoding condition (parameter) and is recorded; and in the reproducing system, the original signal. is restored based on the line number and the parameter for encoding. Since even the signal of a line in the vertical blanking period can be recorded on a tape after being encoded in accordance with the characteristic of this signal and is reproduced, this method is suitable to use a digital VTR of the picture compressing and recording system as a VTR for business. If data contents of the line designated by line designation data are equal between first and second fields, the signal of the designated line restored in the first field is used in the second field also in the reproducing system to reduce the data volume to a half.

Title: Waveform generator
Inventor: TAKEYA HIDEAKI
IPC: G10H7/02
Filed: 1990-11-30
Abstract: PURPOSE:To make reproduction up to a high tone range without increasing the total capacity of a waveform memory by dividing the waveform memory to two groups ; even and odd addresses, according to the lowermost bit of the addresses. CONSTITUTION:An address generating section 100 generates the address ADR for reading out the waveform memory according to the timber and pitch of musical tones. The integer part of the ADR is divided to the even and odd groups according to the lower bit thereof. These groups are respectively outputted as waveform data WA, WB in a waveform computing section 10 via the waveform memories 11, 12. On the other hand, the decimal part of the ADR is outputted as an interpolation coefft. H. These outputs are subjected to processing of (WB-WA)H+WA by computing elements 113 to 115. A DFF 116 latches these values and outputs the values as waveform memory data W. The access for twice of the waveform memories is simultaneously executed at one time in this way and, therefore, the time for computation per tone is reduced by half and the sampling frequencies are eventually increased. The reproduction up to the high tone range is thus possible.

IPC: G01J5/60
Filed: 1998-12-01
Abstract: PROBLEM TO BE SOLVED: To provide a detecting method, for the blackening of a lamp, in which the blackening of the lamp can be detected in real time or in a state close to it without a visual observation. SOLUTION: Spectral radiant energy which is radiated from the sealing body of a lamp 1 is sent to a body part 5b in a spectral radiant energy detector 5 via an optical fiber 5a. A detecting element 5c and a band-pass filter 5d are installed at the body part 5b. Only the spectral radiant energy in a wavelength region to be measured by the band-pass filter 5d is introduced to the detecting element 5c. Since the spectral radiant energy radiated from the sealing body of the lamp differs according to whether the lamp is blackened or not, the blackening of the lamp can be detected by detecting a change in the spectral radiant energy radiated from the sealing body.  In addition, in a lamp in which the temperature of its sealing body is changed, spectral radiant energy radiated from the sealing body is measured at two different wavelengths, and the blackening of the lamp may be detected on the basis of a change in their ratio.
