IPC: H01S5/10
Filed: 1987-05-20
Abstract: PURPOSE:To enable operation of the title laser at a high oscillation efficincy, a low threshold value current and high output, by utilizing the surface azimuth dependence of a liquid phase epitaxial growth (LPE) method for selectively forming a current block layer on the surface except a groove. CONSTITUTION:An n-type InP current block layer 3, a GaInAsP buffer layer 4, a p-type InP clad layer 5, a GaInAsP active layer 6 and an n-type InP protective layer 7 are formed by turns on a p-type InP substrate 1 provided with a groove by an LPE method. Thereby, the layer 3 does not grow in the inside of the groove due to the surface azimuth dependence of the LPE method. The layer 4 has only a little surface azimuth dependency so as to grow in the inside of the groove and the layers after the layer 5 grow also thereon. Later, an inverse mesa type stripe is formed by etching, while n-type and p-type InP current stricture layers 10, 11 are made to grow by the LPE method. When this laser operated, an interface of the layers 3, 4 and the layers 10, 11 becomes an inverse bias, the current does not flow in the part of a grating to be an outer waveguide path. Accordingly, an operation of a good oscillation efficiency, a low threshold value current and a high output can be per-formed.

Title: Square wave-voltage converting circuit
Inventor: UEHARA AKIRA
IPC: G01R29/02
Filed: 1995-05-19
Abstract: PURPOSE: To switch two stages of outputs to each other by obtaining the DC voltage corresponding to the duty by integrating square waves and amplifying the DC voltage by means of a first-stage operational amplifier, and then, intermitting the voltage generated from a reference voltage generating section with a switch and outputting the voltage across an output-stage operational amplifier and the output of the voltage generating section. CONSTITUTION: An integration circuit 2 generates the DC voltage corresponding to its duty by integrating input square waves and an operational amplifier 9 performs noninverting amplification of about a double gain. A reference voltage generating section 23 outputs a reference voltage which is nearly equal to the maximum output value of the amplifier 9 and the input voltage of another operational amplifier 16 is switched by intermitting a switch 15. The amplifier 16 works as a voltage follower circuit having a one-time gain. When the switch 16 is turned off, the output of the amplifier 9 becomes the input of the amplifier 16 and, when the switch 16 is turned off, the average value of the output of the amplifier 9 and reference voltage is inputted to the amplifier 16 by means of a voltage dividing resistor 12.  Therefore, two stages of different voltages can be outputted by switching them to each other by fetching a circuit output from the output sections of the amplifier 16 and the section 23.

Title: Color display element
Inventor: OOKUBO YUKITOSHI
IPC: G02B5/20
Filed: 1983-07-04
Abstract: PURPOSE:To attain a superior display function of no parallax without adding two filters newly, by arranging an optical filter having a perillene pigment in each electrode of a thin film transistor array and giving different spectral characteristics to adjacent filters and overlapping them in their peripheral regions. CONSTITUTION:Thin film transistors (TFTs) 2, 2', 2'', and 2''' are arranged in hatched parts between gate lines 1a, 1a', and 1a'' and source lines 3, 3', and 3'', and optical filters 20, 21, and 22 are formed on them. Filters 20, 21, and 22 have spectral characteristics different from one another and adjacent elements overlap one another. In this constitution, the parallax is not generated because optical filters are brought closely into contact with electrodes of a display part and are formed. Because of overlapping, the effect of absorption of an incident light is enhanced. Films as optical filters are formed easily by sublimation transfer or vapor-deposition, and desired materials are selected from poly-perillene pigments or the like known as an organic dye.
