Title: Compound semiconductor light receiving element and fabrication thereof
Inventor: IWASAKI TAKASHI
IPC: H01L31/10
Filed: 1995-01-23
Abstract: PURPOSE: To prevent dissociation of phosphorus from an epitaxial wafer by covering the part in the wafer, requiring no diffusion, with an anti-diffusion insulation film and covering the exposed part with InGaAs crystal. CONSTITUTION: An InP buffer layer 12, an InGaAs light receiving layer 13 and an InP window layer 14 are grown epitaxially on an n-type InP substrate 11. SiN is then deposited entirely on the surface of a cleaned and etched epitaxial wafer. Subsequently, the part for forming a light receiving region is bored selectively by using a mask. The SiN film 15 serves as a mask for diffusing Zn and forming the underlying layer of electrode. The bored part is diffused with Zn to form the underlying layer for electrode. InGaAs layer 16 added with no Zn is then grown selectively on the SiN film 15. InGaAs crystal is not grown on the SiN film 15 but grown only at the bored part. Since the bored part is diffused with Zn while being covered with InGaAs, dissociation of P can be prevented.

Title: Gradation heat-sensitive recorder
Inventor: SHINOHARA SHINJI
IPC: B41J2/36
Filed: 1996-02-15
Abstract: PROBLEM TO BE SOLVED: To allow correction of gradation density even in the case high-gradation parts can not be adjusted because heating elements have low resistance values and a long energizing period of time is required or in the case low gradation parts exceed the correction limit because the heating elements have high resistance values and the energizing period of time has to be shortened when correction of the gradation density is performed according to the scatter in resistance values of the heating elements. SOLUTION: This gradation heat-sensitive recorder includes a first memory 1, a second memory 2 and an arithmetic circuit 3. The first memory 1 stores head resistance correction values Hm that are gradation values substituted for scatter in resistance values of heating elements of a heat-sensitive recording heat according to differences between the resistance values of the heating elements and a reference resistance value R and an optional gradation number L, and the second memory 2 stores gradation correction width numbers Wn that are shifting values substituted for the gradation value corresponding to the input image data to obtain the same print density within a width between the upper and lower limits of the resistance values of the heating elements.  The arithmetic circuit 3 calculates a correction gradation number Zm to correct scatter in the resistance values of the heating elements from the heat resistance correction value Hm, the gradation correction width number Wn and the gradation value (n) corresponding to the input image data.

Title: Vertical alignment mode liquid crystal display device
Inventor: KOMA TOKUO
IPC: G09F9/35
Filed: 1999-02-05
Abstract: PROBLEM TO BE SOLVED: To provide a vertical alignment mode liquid crystal display device which prevents alignment unevenness generated by fluidized alignment in a liquid crystal injection step for a liquid crystal display device and which has improved display quality. SOLUTION: In an LCD having an alignment controlling means for a liquid crystal other than an alignment layer, an inorganic vertical alignment layer which is not rubbing treated is used. The inorganic vertical alignment layer can prevent alignment unevenness due to fluidized alignment because of its difficulty in forming a pretilt angle. Because the alignment controlling means is provided, for example, with alignment controlling windows 20, alignment controlling electrodes or alignment controlling inclined parts, directions of liquid crystal molecules can be controlled without providing any pretilt angle.

Title: Projector and liquid crystal display (lcd) device for the projector
Inventor: MATSUSHITA YASUHIRO
IPC: G03B21/00
Filed: 1997-02-13
Abstract: PROBLEM TO BE SOLVED: To prevent the generation of the swirl shaped irregularities in luminance on a projected picture while the surface temperature of an LCD panel is increased due to the increase in the light quantity of a light source by forming a transparent temperature buffering film on the surface of the panel. SOLUTION: A transparent temperature buffering film 16 is pasted on the surface of an LCD 4 so that no cooling air 9 directly blows the surface of the LCD panel 4 which has high temperature. The pasted film 16 has a temperature gradient. Therefore, the surface temperature of the side of the film 16, against which cooling air 9 hits, is lowered for 10 deg.C, for example, with respect to the surface temperature of the glass substrate side of the LCD 4.  Thus, the temperature difference between the high temperature air flow generated in the vicinity of the surface of the film 16 and the Karman's vortexes of the air 9 becomes relatively small compared to the case, in which the film 16 is not pasted, the difference between the refractive indexes of the high temperature air flow and the Karman's votexes of the air 9 also becomes smaller and the luminance irregularities, which appear on the projected picture in a swirl shaped manner, are dissolved.
