Title: Integrated circuit device
Inventor: SHIBATA MASAO
IPC: G06F1/00
Filed: 1979-11-19
Abstract: PURPOSE:To make it possible to extend as auxiliary power source to a maximum while reducing electric power consumption greatly by breaking an electric circuit that makes a chip-to-chip connection by closing an AND circuit on occurrence of a low-order signal accompaying a break of a main electric power source. CONSTITUTION:Once the failure of main power source 1 occurs owing to an accident, chip 2 is backed up by auxiliary power source 4 via diode 7. Consequently, information in the memory, counter, etc., formed in chip 2 is held accurately without being erased. On the other hand, since an ''L''-level signal accompanying a break of the main power source is applied to one input terminal of AND circuit 5 via signal line 10, circuit 5 is closed and the electric circuit making the connection between chips 2 and 3 is broken. Therefore, the loop of electric power source 4, chip 2, signal line 9, chip 3, input protection diode 6, and main electric power source 1 is not formed and no undesired current in the backup operation flows. Thus, the electric power consumption can be reduced greatly and the life of electric power source 4 can be prolonged to a minimum.

Title: Optical electronic element
Inventor: HIRATA TAKAAKI
IPC: H01S5/00
Filed: 1987-06-16
Abstract: PURPOSE:To change an effective band gap and reduce optical absorption on the edge face of an active layer, and to prevent the damage of the edge face by optical absorption by applying an electric field to the edge face of the active layer and bending a band. CONSTITUTION:Electrons and holes are injected to an active layer 1 from clad layers 2, 3 in order to oscillate an element. Electrons injected approximately exist on the lower side of the quasi-Fermi level Fc of a conduction band in the active layer 1, holes approximately exist on the upper side of the quasi- Fermi level Fv of a valence band, and a band is bent near an edge face when an electrode 5 is biassed at a positive value under the state. Consequently, electrons in the conduction band are increased on the edge face, holes in the valence band are decreased, and the energy of the light must be brought to energy Eg' or more where electrons in the uppermost section of the valence band can be excited at an energy level higher than the quasi-Fermi level of the conduction band in order to absorb light under the state. That is, an effective band gap is brought to the value Eg' larger than a band gap Eg on the inside, and light absorption near the edge face is reduced, thus preventing the damage of the edge face.

Abstract: PROBLEM TO BE SOLVED: To allow 2nd coding to match with a print speed by applying compression coding again to decoded image data with an algorithm capable of high speed decoding so as to store the image data required for printing to a print buffer in advance at all times. SOLUTION: When image data of one line among image data stored in a reception buffer 21 are decoded and outputted from a decoding section 22, a 2nd coding section 23 conducts fixed length compression coding and stores its output to an intermediate buffer 24. The intermediate buffer 24 has a capacity of at least storing image data by one print paper so that 2nd coding is not in time in the case of high speed decoding and processing resulting in interrupting printing. A high speed decoding section 25 conducts decoding at a speed over the print speed and image data read from a print section 27 are stored in advance in a print buffer 26. That is, the 2nd coding section 23 applies compression coding to the image data in a way that the image data are coded at a speed faster than the print speed of the print section 27.
