Title: Semiconductor device
Inventor: ITABASHI KAZUO
IPC: H01L21/331
Filed: 1989-06-12
Abstract: PURPOSE:To prevent characteristics deterioration of a bipolar transistor by forming a layer of an opposite conductivity type whose concentration is lower than that of an emitter diffusion layer at an end section thereof. CONSTITUTION:Arsenic is masked by an oxide film 7a formed to a sidewall of an emitter opening section and diffuses inside an N<->-type diffusion layer 8a to form an N<+>-type emitter diffusion layer 8b of high concentration. Therefore, an electric field inside a P-N junction is relaxed as compared with a usual structure wherein a P-N junction is formed directly between an end section of an emitter diffusion layer of high impurity concentration and an inner base diffusion layer 6, thereby restraining generation of hot carrier. According to this constitution, it is possible to prevent characteristics deterioration of a bipolar transistor.

Filed: 1977-12-12
Abstract: PURPOSE:To eliminate the accommodating mistake of a magnetic disc pack in a corresponding case due to carelessness by making it possible to joint the block at a pack case and the block at a disc pack with the use of a unique key. CONSTITUTION:A disc pack body 2 and a flange 4 are formed with key portions 11 and 12, respectively, so that they can be fitted with the same width of the key grooves of the key portions 11 and 12. On the other hand, the other disc pack device is formed with a key portion having a different groove width. As a result, since the key portions 11 and 12 other than the paired devices cannot be combined, the engagement between the body 2 and the glange 4 at the pawl portion 7 does not take place. As a result, it is possible to prevent the accommodating mistake of a magnetic disc pack in a corresponding case due to carelessness.

Filed: 1993-06-21
Abstract: PURPOSE:To perform a numbering operation of a wide range of application by showing the number updated by an updating means at the cursor position designed by a position designating means by the instruction of an instructing means. CONSTITUTION:A numbering operation is performed when a microprocessor CPU identifies a fact that a number set key (a key NS) included in a function key group of a keyboard KB is pushed. That is, a number is given to the present cursor position when the key NS is pushed. The value stored in a number register NR is converted into a code of the corresponding numeric character. This numeric character code is set at the cursor position and the number is displayed. Then the value stored in an increased value register AR is added to the contents of the register NR so that the next value is set with push of the key NS. Thus it is possible not only to give a number to a desired position designated by a cursor but to set the changed variable produced by a numbering operation at a desired level.

Title: Treating method for desulfurized waste liquid of coke oven gas
Inventor: SAKURAI YUUZOU
IPC: C02F1/74
Filed: 1977-12-14
Abstract: PURPOSE: To convert thiocyanate ion, thiosulfuric acid radical and free sulfur etc. to sulfuric acid radical and to prevent corrosion of reactor material, by carrying out oxidation reaction of desulfurized waste liquid at a fixed temperature adding a fixed amount of copper and ammonia water.  
     CONSTITUTION: Metallic copper, copper alloy or copper sulfate etc. and ammonia water, are added to desulfurized waste liquid so as the concentration of copper in waste liquid to be less than 50 ppm. Next, wet process oxidation reaction is carried out under the condition maintaining at least a part of the liquid in liquid phase by supplying oxygen etc. at more than 150°C of reaction temperature. Hereby, all of thiocyanate ion, thiosulfuric acid radical, free sulfur in the waste liquid, are converted to sulfuric acid radical. By the above method, good conversion rate is able to obtain at about 5 ppm of copper concentration and low reaction temperature. Gas is separated from liquid in the waste liquid after treatment and waste gas is discharged in the atmosphere. Liquid is discharged as it is, because COD and copper ion concentration, are low.

Abstract: PURPOSE: To obtain quartz glass having a good absorption characteristic in a UV range and a good permeation characteristic in a visible light spectral range by doping a fluorescence suppressing material to the quartz glass having UV inducible fluorescence within the visible light spectral range by a UV absorbent doping material.  
     CONSTITUTION: This quartz glass contains the UV doping material contg. cerium (compd.). Praseodymium (compd.) is further doped into the quartz glass in order to drastically reduce the blue fluorescence of the cerium excitable by UV rays. The doping material and doping quantity are so determined that the absorption end of the quartz glass exists at a wavelength of about 320 nm. Consequently, the UV rays are not actually permeated or only the permissible quantity thereof is permeated. Cerium-praseodymium aluminate is further preferably mixed with the quartz glass before melting of the quartz glass. Additional doping of a barium-boron compd. also leads to the further reduction of the fluorescence of the quartz glass.
