Title: Ink jet head
Inventor: YANAI HITOSHI
IPC: B41J2/05
Filed: 1987-07-06
Abstract: PURPOSE:To enable printing to be performed at high speed, to make resist coating in manufacture uniform and besides, to prevent an electrode from being injured, by providing an ink feed opening to a support member of a closing plate which has a substrate and nozzle holes. CONSTITUTION:Ink in an ink reservoir part is fed to a common ink chamber 7 via an ink feed opening 12, and the ink which has been fed in this common ink chamber 7 is made to flow into each ink chamber 6. Then, when current is applied to an ink discharge pressure generation element 9 via an electrode 10, the ink in the ink chambers 6,...6 receives pressure by the ink discharge pressure generation elements 9,...9, and is discharged from nozzle holes 11,...11, then is adhered onto a material to be recorded, and a character or the like are printed. In the case where an ink jet head is manufactured, since the ink feed opening 12 is provided to a support member 13, it is not required to form the ink feed opening to a substrate 1. Thereby, resist coating can be made uniform when the electrode 10 is formed and further, even after forming an electrode pattern, the electrode 10 will be damaged.

Abstract: PROBLEM TO BE SOLVED: To reduce secondary bird's beaks formed by a natural oxide film by forming a pad oxide film on a semiconductor substrate, forming an oxide buffer layer, nitriding its surface to form a nitride film and then forming an anti-oxidation film thereon. SOLUTION: A pad oxide film 12 is formed on a semiconductor substrate 10, an oxide buffer layer 14 is formed thereon, and after its surface is nitrided to form a nitride film 16, an anti-oxidation film 18 is formed thereon. For example, the anti-oxidation film 18 is formed by vapor-depositing silicon nitride, a photoresist pattern is formed thereon, and the nitride film 16 and the anti- oxidation film 18 are selectively corrosion-resistant-etched. Then a field oxide film 20 is formed on an element isolation region wherein the exposed substrate has been selectively oxidized by utilizing a thermal oxidation process. The anti-oxidation film 18, the nitride film 16 and the oxide buffer layer 14 which are formed on an active region are sequentially removed thereafter to complete the element isolation region on the semiconductor substrate 10.

Title: Image forming device
Inventor: YAMAMOTO TAKEMI
IPC: G03D13/00
Filed: 1988-07-05
Abstract: PURPOSE:To use the image forming device even in a high-humidity state without any trouble by conveying a sheet type drying agent which is set in a form cassette or held in the device for dehumidification to a heating means in the device and drying the agent. CONSTITUTION:The sheet drying agent 30 serves for moisture protection by reducing the area of contacting with the outside air by covering developed paper 20 in addition to the effect of dehumidification. The sheet type drying agent 30 decreases in dehumidifying ability when containing moisture to some extent, so the agent is sent to a heat fixing device 41 constituting a heating means through the conveyance path for the developed paper 20 constituting a conveying means with the signal from an external switch or manually and then dried there. The sheet type drying agent 30 which is dried by passing through the heat fixing device 41 is sent to a tray 42 and fitted to the developed paper cassette 21 again. Consequently, the device is usable even in the invariably high humidity state without any trouble.

Abstract: PURPOSE: To easily and rapidly improve physical properties, e.g., air permeability, of a muddy material of high water content with a high efficiency, by adding and mixing the muddy material with a high molecurar compound of high water absorption.  
     CONSTITUTION: A muddy material of high water content is added and mixed with a high molecular compound of high water absorption, in order to improve the air pemeability of the muddy material whose high water content causes troubles during a disposal operation. The muddy material may be a sludge generated as a by-product in a water decontamination process or excretions of cattles. The high molecular compound is an addition or graft polymerization product of a starch of cellulose with acrylic acid, acrylonitrile, etc., or a bridged or polymerized product of an acrylic salt type compound. The high molecular compound is preferably one capable of retaining water therein at a mix. rate of 300 times its own weight. Owing to the usage of the high molecular compound, a modifier is not necessary, and also there is not a substantial increase in a volume of the muddy material to be treated. Consequently, it is possible to elongate a reserving period of the muddy material in the fermentation vessel.

Inventor: NISHIKADO TORU
IPC: B23K13/00
Filed: 1989-06-30
Abstract: PURPOSE:To prevent generation of stepped flaw on a pipe part corresponding to the concave arcked part of a roll by forming a linear relief part between a concave arcked part and a convex arcked part on a squeeze roll. CONSTITUTION:When the surface of roll, which is brought into contact with a open pipe, of the squeeze roll 10 is observed about its sectional shape, it can be divided into three parts of the concave arcked part 15, linear relief part 19 and convex arcked part 15. Because that linear relief part 19 is continued on the end part of the concave arcked part 15 and is elongated in the tangential direction of the concave arcked part 15, the relief part is made into an opened shape outwardly from the concave arcked part 15. Therefore, even if springback of the open pipe is occurred, the displacement of pipe due to the springback can be successfully relieved. As the result, increase of contact pressure which has been usually occurred on the convex arcked part 16 can be restained and the generation of stepped flaw can be prevented.

Abstract: PURPOSE:To suppress abnormal discharge due to concentration of an electric field in a second electrode by specifying the viscosity of a paste material to form a base layer between a second substrate and a second electrode. CONSTITUTION:Plural numbers of base layers 13 are formed at an equal interval on a substrate glass 11, and plural numbers of discharge electrodes 10 are formed on the respective base layers 13.

Abstract: PURPOSE:To output data by superimposing in memory small in capacity by attaching a bit magnification change function even when the resolution of two image data to be superimposed are different. CONSTITUTION:When the resolution of the image data is set in 1:1 in a switch control circuit 23, original image data is formed by inputting high-order and low-order bits (a) and (b) at a gate 24.

Abstract: PURPOSE:To perform deodorization of sulphureous odor like H2S and ammoniacal nitrogen odor by one treatment effectively by using combined layer of peat layer with soil layer or adsorbent layer. CONSTITUTION:A first layer 1 comprising peat and a second layer 2 comprising soil, adsorbent, etc. are packed as a deodorizing material in the inside of a concrete bottomed tank 3. Odorous gas is fed from an introducing pipe 4, dispersed by a dispersing pipe 6, and fed to the peat layer 1 through a pebble layer 8 and a net 9. The peat layer 1 removes primarily sulphureous odor. The gas is sent to the soil layer 2 (or adsorbent layer), where ammoniacal nitrogen odor is primarily removed. Deodorized gas is discharged to the outside of the apparatus. SO4<2-> which has accumulated in the peat layer reacts with NH3 to form ammonium sulphate, which is eluted by the natural rain water or by sprinkled water from a sprinkling nozzle 12 and discharged as drain from a catch basin 22.

Abstract: PURPOSE:To secure the system stability even in an application field where the secrecy is required by using a control means which inhibits the execution of a specific instruction with use of a discriminating signal which shows that an input ID code received from an ID code discriminating means is not equal to the specific one. CONSTITUTION:An ID code discriminating means 5 discriminates whether an input ID code is equal to the specific one or not. A control means 7 inhibits the execution of a specific instruction with use of a deciding signal showing that the input ID code outputted from the means 5 is not equal to the specific one. Thus all instructions are available in case the ID code received from outside is equal to the specific one. While the number of available instructions is limited in case said input ID code is not equal to the specific one. Thus the system stability is secured even in an application field where the secrecy is required.
