IPC: H01L29/732
Filed: 1990-02-27
Abstract: PURPOSE:To provide a good Schottky diode by heat-treating a whole substrate to alloy a Schottky electrode with a silicon surface. CONSTITUTION:The layers for an aluminum Schottky electrode 20 and an aluminum-silicon ohmic electrode 25 are deposited in a manner that the connection 30 between the Schottky electrode 20 and the ohmic electrode 25 is away from a Schottky junction 23. The ohmic electrode layer 25 on the Schottky electrode layer 20 is patterned by a lift off technique to form both electrodes. A heat treatment is carried out for annealing and the alloying of the Schottky electrode 20. Since the connection 30 between aluminum and aluminum-silicon is separated from the Schottky junction 25, only one annealing process is required, and the ohmic electrode and the Schottky electrode from good contact. Thus, a good Schottky diode is provided.

Title: Measuring device for minute cubic volume
Inventor: ANNO GOUSUKE
IPC: G01N31/16
Filed: 1982-03-26
Abstract: PURPOSE:To enable measuring of a cubic volume according to a diameter of a liquid drip, by a method wherein a nozzle, through which liquid is dripped, is situated, a light source and a light receiving element group, which are located below the nozzle, are positioned facing and opposite to each other, and a projection image is detected and measured by the light receiving element group. CONSTITUTION:Liquid is dripped through a nozzle 1, and a pair of a light source 2 and a light receiving element group 3 are positioned at a specified distance  below the nozzle. An optical system is adjusted so that light from the light  source produces a parallel light, and when the drip passes through the light, a  shadow in a similar figure is produced at its background. If the receiving element group 3 such as CCD is located at a portion where the shadow is produced,  the element group is divided into elements which are shined by a bright light  and elements which are shadowed and darkened. In the receiving element, in order to read out the details thereof at intervals of a given time, only outputs of  m-piece of the elements as shown in a drawing produce a low level. Through  previous counting of the number of elements of not higher than a level, the size  of the shadow can be determined. This permits the detection of the drip diameter, thereby a cubic volume can be found by its calculation.

Title: Ink-impregnated platen for printer
Inventor: EGUCHI YASUMASA
IPC: B41J27/20
Filed: 1984-03-14
Abstract: PURPOSE:To obtain an ink-impregnated porous body having favorable printing property and durability, by a method wherein a sintered nylon body having a capillary suction pressure varied at a negative gradient from the printing surface side toward the side of a fitting surface for fitting to a platen substrate is impregnated with an ink. CONSTITUTION:In an ink-impregnated platen type printer, an ink-impregnated platen obtained by fitting an ink-impregnated porous body to a platen substrate to form a printing surface is faced to a printing head through a printing paper. In the printer, the ink-impregnated porous body is produced by a method wherein a sintered nylon body having a capillary suction pressure varied at a negative gradient from the printing surface side toward the side of a fitting surface for fitting to the platen substrate is impregnated with an ink. Namely, since the capillary suction pressure of the sintered body for the ink is determined by the size and the number of pores and is increased with a decrease in the pore diameter and an increase in the number of the pores, the sintered nylon body is produced in consideration of these points. Accordingly, an ink-impregnated platen can be obtained which can smoothly supply an ink to the printing surface, can maintain a favorable printed condition for a long period of time and has excellent printing property, high surface strength and excellent durability while sufficiently enduring the impact of a printing wire.

Title: Method and apparatus for treatment of exhaust gas
Inventor: KAWAMURA SATOSHI
IPC: B01D53/56
Filed: 1990-03-01
Abstract: PURPOSE:To easily decompose NOx into N2 and O2 by discharge by introducing the exhaust gas allowed to pass through a dust removing bed into a discharge region packed with ceramic particles to decompose the gaseous components in the exhaust gas. CONSTITUTION:The dust in inlet gas 7 is filtered by a fine particulate ceramic filter 3 to be accumulated on the filter 3 and, after the dust is backwashed and shaken off by backwashing gas 9, the dust is stored in a hopper to be discharged out of the system. The gas from which dust is removed passes through a coarse particulate ceramic particle (diameter, about 0.1-1mm) paked bed 2 being a discharge region without generating clogging. During this passage, voltage is applied to electrodes 4, 5 from a power supply 6 to generate silent discharge and NOX in the gas is directly decomposed into N2 and O2 by this plasma to be discharged out of the system as outlet gas 8.

Title: Trigger element peak point characteristic measuring unit
Inventor: ISOBE KATSUYOSHI
IPC: G01R31/26
Filed: 1978-04-20
Abstract: PURPOSE: To reduce the number of steps to perform measurement efficiently by making the voltage step width of the applied current rise to a measured element large first and small gradually.  
     CONSTITUTION: A fixed voltage is supplied from 5 to measured element 1, and the current value of current source 2 is set to Δx, thereby detecting turning-on and off in 3. At a turning-off time, the current value is raised by Δx; and at a turning-on time, the current of the current source is set to 0 to turn off the element. Next, the current source is set to the addition average value between maximum applied current value Δx at a turning-off time of element 1 and minimum applied current value 2×Δx at a turning-on time. Turning-on and off states are detected again to obtain a current value to be set next. This operation is controlled by 6 to be repeated until the difference between the minimum applied current value under the turning-on state of element 1 and the maximum applied current value under the turning-off state becomes a current value of resolution required for measurement. A peak point characteristic is measured by the maximum applied current under the turning-off state at this time.
