Inventor: TAKAHASHI NORIYUKI
IPC: G06F3/06
Filed: 1990-03-20
Abstract: PURPOSE:To efficiently operate the magnetic tape library device by utilizing a copy in the own system, and judging at high speed whether a request volume exists in the library device or not, at the time of volume use request from a job by a host system. CONSTITUTION:A host system 1 has a copy 10 of a control memory 7 in its main memory. The contents of the copy 10 are obtained by reading out the contents of the control memory 7 in a magnetic tape library device 2, and rearranging them in order of the volume serial number. At the time of start of a job, the host system 1 searches at a high speed the copy 10 of this control memory, and judges whether a volume requested from the job exists in the library device 2 or not. In the case the target volume exists in the library device 2, the host system 1 instructs immediately the mount control of the volume to a library controller 5. In such a way, the library device 2 can be operated efficiently.

IPC: H01S5/00
Filed: 1993-03-30
Abstract: PURPOSE:To obtain a multi-wavelength surface emission semiconductor laser element having a vertical resonator structure of very low light absorption by stacking at least two sets of active layer structures having different oscillation wavelengths vertically and integrating. CONSTITUTION:When a current is injected from lateral direction, laser oscillation takes place in emission active layers 4, 11 and 15 which thereby produce lights having wavelengths in the vicinity of 630nm, i.e., red region, 530nm, i.e., green region, and 460nm, i.e., blue region, respectively. Since a white laser light mixed with primary colors can be taken out from a high reflectance film 20 on the opposite side to a substrate 1 and the emission active layers 4, 11, 15 are driven simultaneously, the laser element functions as a white laser light source mixed with three primary colors at all times in one space. Since a multi- wavelength laser light source can be provided for one space, a multi-wavelength surface emission semiconductor laser element having vertical resonator structure of very low light absorption can be realized.

Title: Transmission system and receiver for still picture information
Inventor: FUJIOKA YOICHI
IPC: H04N7/08
Filed: 1992-02-24
Abstract: PURPOSE:To increase the transmission speed of a telephone circuit by allowing the luminance of each picture element sample of a still picture to alternately correspond to the amplitudes of respective half periods of two carrier waves, which have the same frequency and are different by 90 deg. at every sample and transmitting the still picture. CONSTITUTION:A video signal is amplified by an amplifier 12 and digitized in an A/D converter 13 based on the clock generated by a PLL circuit 15 and stored in a picture memory 20. When transmission is instructed, a computer 21 controls a CRT controller 16 to read out pixel data from the memory 20 one by one and uses two sine waveforms, which have 90 deg. phase difference and have the same frequency, to modulate data by allowing the pixel level of every other data to correspond to the amplitude of the half period of each waveform. These two waveforms are shaped by filters 24 and 25 and synthesized by a synthesizing circuit 26. When respective pixel data are equalized to the maximum value of sine waves at this time, the maximum value of each waveform is present on the synthesized waveform, and four pixel data are transmitted in one period; thus, the transmission speed is increased.
