Filed: 1998-08-07
Abstract: PROBLEM TO BE SOLVED: To provide a liquid crystal display device which can control reflectance at a boundary between an alignment film and liquid crystal and which can suppress occurrence of interference fringes. SOLUTION: On the rear side of a front glass substrate 2 of the liquid crystal display 1, Al2O3 film having λ/4 optical film thickness and a transparent electrode 3 composed of ITO and having λ/2 optical film thickness are formed by a vapor deposition method. Al2O3 film is formed as a front alignment film 4 and is subjected to alignment treatment. λ is the wavelength of a bright-line causing interference fringes and a middle value is adopted if there is plural bright-lines. To form the front alignment film 4, the film is vapor-deposited by holding the front glass substrate 2 inclined at 65 deg. with respect to a vapor deposition source.  A rear alignment film 8 to be formed on the side of a rear glass substrate 5 is also formed with Al2O3 in a similar manner to form the front alignment film 4 and both glass substrates 2, 5 are stuck to each other to enclose liquid crystal 9 in between. Owing to a configuration thus formed, reflectance at a boundary between the liquid crystal 9 and the front alignment film 4 can be controlled to be <=0.5% and occurrence of the interference fringes can be suppressed.

Title: Data transmission system by modem
Inventor: OKANO HIROTAKA
IPC: H04L27/00
Filed: 1990-08-29
Abstract: PURPOSE:To attain high reliability of data transmission by adding an end pattern after a data in the case of data transmission controlling the transmission of a modulation wave. CONSTITUTION:A sender side MODEM adds an end pattern 5 after a data from a terminal equipment and sends the result. Then a host side MODEM 102 uses a synchronizing signal 3 of a MODEM 105 at the side of a terminal equipment A to apply initial setting of a reception section. Then a data 4 is received and it is sent to a host 101 and when momentary interrupt takes place in an incoming transmission line 108 on the way of data transmission, the data is intermitted and an error takes place. Since the host side MODEM 102 does not detect the end pattern 5, an error in the received data is recognized. Thus, the end of the data is clearly discriminated and highly reliable data transmission is attained.

Abstract: PURPOSE:To obtain a semiconductor laser device which has a large output without making an active layer thinner by a method wherein an n-type GaAs substrate is made to be doped with a p-type impurity and its surface is subjected to etching. CONSTITUTION:When a bias is impressed between a p-type electrode 10 and an n-type electrode 11 so as to make the p-type electrode 10 positive, a current does not flow through a region where a current blocking layer 7 is intervened, as the region is provided with a pnpn junction but a current flows through only a ridge section 8. But a current does not flow through a region even of the ridge section 8 where a p-type GaAs layer 2 is provided, as a pnpn junction composed of an n-type GaAs substrate 1, a p-type GaAs layer 2, a first clad layer 3, an active layer 4, and a second clad layer 5 is provided to the region. Therefore, the generation of heat due to a current does not take place at an end face. So, temperature of the end face does not rise, and even if a spot of laser rays is the same in size at the part where laser rays are guided, a COD level is made to be higher to enable laser rays to become larger in output.

Abstract: PURPOSE:To provide materials and manufacturing process that are applicable in performing an optical communication, materials of which are cheaper than those of a green emission element where a GaAsP inclined layer is prepared on a GaAs substrate and, designs of which can be performed as an element in an arbitrary manner by causing an InGaP mixed crystal of 0.5-0.75 in terms of mol fraction of GaP to grow stepwise on a GaP substrate. CONSTITUTION:A gallium phosphide (GaP) substrate is arranged at the upper side and an InGaP alloy having a composition of 0.50-0.75 in terms of mol fraction of GaP is arranged at the lower side and its intermediate part between the above two sides is filled with an In-Ga solution that deposits indium/gallium phosphide (InGaP) of around 0.85-1.0 in terms of GaP mol fraction when such a crystal growth starts. Then, a solute that is dissolved from a raw material alloy side by fluctuating simultaneously temperatures of the GaP substrate, raw material alloy, and the solution at a some temperature difference is transported to a GaP substrate crystal side. Subsequently, the solute permits an InGaP epitaxial layer where InP mol fraction is stepwise added to grow and after cycling a temperature several times the solute also permits an InGaP single crystal where a mixed crystal composition in 0.5-0.75 in terms of GaP mol fraction to grow. And furthermore, pn junction is formed on the InGaP single crystal by a diffusion or a liquid growth technology. A material for emission element having such a structure makes it possible not only to take out light in an arbitrary direction but also to perform designs regarding the emission element for an optical communication from more unrestricted standpoints.
