Title: Method of reducing sticking of contact elements
Inventor: DAGURASU EI UETSUBU
IPC: B05D7/00
Filed: 1995-03-20
Abstract: PURPOSE: To reduce the risk of sticking of a coated element with another contact element by forming a protective layer on a first contact element by using polymer coating to form a coated element. CONSTITUTION: An address and a control circuit are formed on a semiconductor substrate 12, then an address electrode 16 and an earth electrode 14 are formed on the semiconductor substrate 12, and polymer coating is formed on the earth electrode 14. For forming the polymer coating, a polymer deposition layer 22 and a mask layer 24 are formed. After patterning the polymer deposition layer 22, by using the mask layer 24, a mean polar board radio frequency(RF) ashing process is applied at first to remove exposed parts of the polymer deposition layer 22. Then the mask layer 24 is removed by using a remote plasma-asher. By practising two etching processes, a protective layer 26 is formed in a desired region, thus a deposition mirror device(DMD) having the protective layer 26 is provided.

Title: Reflector and liquid crystal display device using the same
Inventor: NAKAI YUTAKA
IPC: G02F1/1335
Filed: 1999-03-10
Abstract: PROBLEM TO BE SOLVED: To obtain a reflector and a liquid crystal display device suitable for mass production and having high latitude for designing by forming a reflection face having smooth spherical recesses and projections and controlling the distribution of the inclination angle of the reflection face to have a specified or larger max. value near the recesses and projections. SOLUTION: A photosensitive resin 2 is applied on a substrate 1 (b) to form a photosensitive resin film 3 having recesses and projections (c). The photosensitive resin 2 is deformed in a heating process to form a photosensitive resin film 4 having smooth recesses and projections (d). Then aluminum is deposited to about 300 nm thickness to form a reflection layer 5 by sputtering on the surface having recesses and projections of the obtd. photosensitive resin film 4 to produce a reflector (e). The inclination angle of the reflector is measured with a contact step meter to obtain the distribution of the angle. From the measurement, it is found that the inclination distribution of the recesses and projections after thermal deformation of the photosensitive resin film 2 can be controlled by the pitch of the projections or recesses.  The inclination angle is the angle between the slope region and the surface of the substrate 1. The obtd. reflector has the distribution of the inclination angle of the reflection face with >=5 deg. max. near the recesses and projections.

Title: Lamp control circuit of electronic watch

IPC: G09G3/00
Filed: 1979-05-21
Abstract: PURPOSE: To control the lamp lighting current at the initial period of lighting within a constant value by controlling a switch by way of clock pulses and controlling the electric current for lighting the lamp for lighting by periodic negative feedback.  
     CONSTITUTION: When the voltage corresponding to the driving current of a lamp 1 by a shunt resistance 7 is applied to a comparator 11 and becomes more than the divided voltage by voltage dividing resistances 19, 20, the output of the comparator 11 inverts and the resistance of a predrive transistor 9 becomes high resistance through the analog switch which is controlled of opening and closing periodically by clock pulses. According to this, the resistance of a transistor 6 becomes high resistance as well and the driving current of the lamp 1 is so controlled by periodic negative feedback controlling as to become constant current. Hence, no rush current is generated at the initial period of lighting and the lamp lighting current becomes within a fixed value, whereby the occurrence of malfunction or the like of the IC circuit owing to the sharp drop of the source battery voltage is prevented.

Title: Optical semiconductor device and manufacture thereof
IPC: H01S5/00
Filed: 1992-03-19
Abstract: PURPOSE:To lessen an optical semiconductor device in light absorption by a method wherein an atom rearranging layer is used. CONSTITUTION:A bias voltage is applied between an anode 101 and a cathode 110, and light rays are made to impinge on a substrate from the rear side. In result, a current is made to flow through a phototransistor composed of a collector 107, a base 108, and an emitter 109 and a surface emission laser composed of a P-type semiconductor multilayer film 103, an active region 105, and an N-type semiconductor multilayer film 106. When the current concerned exceeds the oscillation threshold value of the surface emission laser, the laser starts oscillating, so that laser rays can be obtained from the rear of the substrate. At this point, the outputted laser beams are partially absorbed by the phototransistor to keep it emitting light rays after light rays are stopped to impinge on the substrate. At this point, an atom rearranging layer is used in place of a graded layer as a layer which couples a plane emission laser and a phototransistor together. By this setup, emitted light can be lessened in absorption.
