Title: Semiconductor laser device
Inventor: IBE HIROYUKI
IPC: H01S5/00
Filed: 1987-03-17
Abstract: PURPOSE:To switch oscillation wavelengths at high speed by utilizing the difference of oscillation wavelengths due to the difference of the axial modes of a semiconductor laser and selecting oscillation axial modes in response to incident beams to the laser. CONSTITUTION:One axial mode is selected and a semiconductor laser 10 having two oscillation axial modes such as a distributed feedback type (DFB) laser is oscillated in the semiconductor laser 10, and an oscillation mode is changed over by mode jumping in the laser 10 when beams having a wavelength corresponding to the other axial mode are projected to the laser 10. That is, the oscillation wavelength of the semiconductor laser 10 can be switched by stable input beams 21 from the outside. Memory and arithmetic operation by the difference of wavelengths can be conducted by utilizing hysteresis characteristics between the intensity of input beams 21 and the oscillation wavelength of output beams 11. The switching of oscillation axial modes is used, thus allowing operation at high speed.

Title: Clock control system by scan-out data
Inventor: FUKUCHI HIROYUKI
IPC: G06F1/04
Filed: 1990-03-15
Abstract: PURPOSE:To improve quality by fixing an address in a scan address register. CONSTITUTION:When checking hardware, a fixed scan address register SADR 1 is selected by an address selector SEL 11 so as to always read out a designation signal as scan-out data. At such a time, when the said data is coincident with trigger data 3, a mode set signal 2 is made effective and a clock signal is stopped so that the hardware can be turned to an arbitrary state. Next, when a single cycle mode is set and the signal 2 is made ineffective, an SADR 10 is selected by the SEL 11 and a clock stop signal is canceled. Thus, since the clock is stopped by the arbitrary signal in the hardware so as to confirm the function of the hardware, to investigate a fault or to investigate causes efficiently at the time of debugging, the quality of a computer main body system can be improved.

IPC: H04N1/407
Filed: 1994-03-31
Abstract: PURPOSE:To enable color reproduction faithful to the color taste of an original including signals outside a color reproduction range by making background level adjustments independently for plural color component signals. CONSTITUTION:A color space compressing circuit finds a dark level by MIN 301 to detect a background level (RGB), and finds a color distribution obtained by detecting the color signal having the highest saturation among color signals exceeding the color reproduction range of a color output part as to the basic primary colors. Then maximum levels R', G', and B' which can be reproduced are set for the respective values of the background level, color distribution, and dark level and matrix coefficients are calculated by multiplying circuits 305-312. At this time, a term of RXGXB calculated by the multiplying circuit 311 is concerned in a chromatic background level, and the background level can be adjusted in consideration of the color taste of the background, i.e., the color component ratio of the background. Consequently, an image that a user desires can be obtained.
