Title: Surface light emission device
Inventor: HAMADA TADASHI
IPC: G02F1/1335
Filed: 1991-09-27
Abstract: PURPOSE:To obtain the surface light emission device which is reduced in constitution size and improved in reliability by surrounding the gap between a light scattering member and a light reflecting member, and a light source with a light absorbing member. CONSTITUTION:For the light guide plate 29 of the same size with a conventional light guide plate, the distance L15 between the effective area 43 of the light guide plate 29 corresponding to the display area 42 of a liquid crystal display element and a light source 33 is reduced to, for example, about 15mm. Consequently, the surface light emission device 21 is reducible in size. The effective area 43 comes closer to the light sources 33 and 34 as a result of the size reduction, so the light emitted from the effective area 43 loses symmetry in this state. For the purpose, a takeout part 39 is provided to take the light of the light source 33 out of the takeout part 39 and the light is absorbed by the light absorbing member 40 surrounding the takeout part 39. The quantity of light at the part closest to the light source 39 in the effective area 43 can be suppressed to make the light emitted from the effective area symmetrical.

Abstract: PURPOSE:To contrive a reduction in a contact resistance and the stabilization of the contact resistance by a method wherein in the case where a silicon- containing aluminum alloy wiring is formed, the epitaxial growth of a silicon film, which is generated on a silicon substrate in a contact hole, is prevented from being generated. CONSTITUTION:A BPSG film or an insulating film 13, such as a PSG film, formed on a silicon substrate 11 is selectivery etched using a photoresist as a mask to make a contact hole 14. After the substrate 11 in the hole 14 is subjected to HF cleaning and a natural oxide film or the like is previously removed, a cleaning treatment using SC1 to SC2 is performed to form a silicon oxide film 15 on the surface of the substrate 11 and after that, a silicon- containing aluminum alloy wiring 16 is formed on the film 15.

IPC: H01L21/768
Filed: 1984-11-27
Abstract: PURPOSE:To form a pattern having excellent dimensional accuuracy by dividing a process into two steps of a pre-step and a post-step and making the etching rate of a polyimide film larger than the developing rate of a resist at the post- step. CONSTITUTION:Polyamic acid is applied onto a ceramic substrate 1, and baked for thirty min at 140 deg.C, thus forming a polyimide film 2 (approximately 2mum film thickness) under the semi-imide state called a B stage. A positive type photo-resist 3 is applied onto the upper layer of the film 2 in approximately 2mum, baked, exposed by using a predetermined photo-mask to shape a pattern image I, and dipped into a developer, thus forming a resist pattern. The ceramic substrate is moved ito a further diluted second solution, and the polyimide film 2 is etched. The development of the resist also progresses slightly (within 1.5mum) at that time, but the developing rate is far smaller than the etching rate of the poluimide film. Accordingly, the pattern for the polyimide film shaped has excellent dimensional accuracy.

Title: Metallic constituent analyzer
Inventor: FUNABASHI TATSUYA
IPC: G01N30/06
Filed: 1992-09-18
Abstract: PURPOSE:To prevent leakage of liquid from piping or couplings by preventing concentration of unionized metallic constituents in a pH conditioner thereby preventing constriction of channel causing pressure increase in the upstream part. CONSTITUTION:A channel switching valve 79 for discharging sample liquid to the outside of channel is disposed in a sample liquid supply path 30 between a reactor 3 and a pH conditioner 50 and the valve 79 is operated based on a detection value of a temperature sensor 86 disposed in the reactor 3. When the temperature in the reactor 3 increases insufficiently for completely ionizing metallic constituents or other fine particles of a sample liquid in the reactor 3, the sample liquid is not fed to the pH conditioner 50 having ion-exchange membrane structure. This constitution prevents concentration of undissolved constituents in the pH conditioner 50 thus preventing leakage of liquid from piping or the like due to constriction of channel casing pressure increase in the upstream part.

Abstract: PURPOSE:To maintain high reliability by receiving information indicating whether overdischarge is generated in a battery or not at the disconnection of a main power supply and executing its counterplan operation on the basis of a previously fixed rule in accordance with the received contents. CONSTITUTION:If overdischarge of the battery is detected because of any cause at the disconnection of the main power supply, i.e. battery discharge, the detection is informed from a battery backup unit 3061 to a CPU301 through a signal line 310 for informing the overdischarge detected result. On the basis of the informed result, the CPU301 selects to shift toautomatic job continuous execution operation or not. Consequently, a storage device 302 of which contents are destroyed is prevented from being directly read out, so that the CPU can be prevented from runaway or loop status.

The output of the potential comparison circuit 5 outputs logic 0, a buffer circuit 1 is turned off and a bus is driven from a waveform output terminal 4 only by a second buffer circuit 2.  The first output buffer circuit 1 is turned off at the temperature of not less than the temperature Tb. The current driving ability of the output buffer circuit driving the waveform output terminal 4 is reduced.

Abstract: PURPOSE:To discriminate a specific cylinder by the signal in one system by installing a revolution signal generator which generates the signals representing the first and second standard positions corresponding to each cylinder in synchronization with the revolution of an engine and offsets the second standard position only in the specific cylinder. CONSTITUTION:A microcomputer 10 calculates the 'high' level output period (t) and the starting-up division cycle T of the signal on the basis of the signal sent out through an interface circuit 9 from a revolution signal generator 8. The ratio t/T or t/(T-t) is calculated for each cylinder. Then, the average threshold value which is the average of the above-described ratio for all the cylinders is calculated. Then, the value of the ratio in each cylinder and the average threshold value are compared. When the result of the judgement is large, a specific cylinder is discriminated, and in this case, #1 cylinder is discriminated. If the result of the judgement is small, return is performed. Thus, when the #1 cylinder is discriminated, other cylinders can be discriminated in the order of #3 cylinder - #4 cylinder - #2 cylinder successively.
