Title: Method for storing, method for recording, device for recording, method for reading and device for reading digital value for memory medium, and memory medium for storing digital value
Inventor: TAKEUCHI MASAMI
IPC: G06K7/12
Filed: 1988-05-19
Abstract: PURPOSE:To store and read out sound information, program information, data information, etc., by storing digital values in recording points arranged at a fixed interval on the surface of a memory medium such as a sheet having a printable surface. CONSTITUTION:Different digital values to be stored are stored by arranging colored dots colored differently from the ground color of the surface of a memory medium M on the surface of the medium M at a fixed internal and with different printing states. The arrangement of the colored dots with different printing states on the surface of the memory medium M at the fixed interval can be easily executed by using various printers such as a thermal printer. The stored digital values can be read out by detecting the different printing states. The printing states can be detected by means of an image sensor, OCR (an optical code reader) or the like.

Title: Forming method of polycrystalline silicon multilayer wiring
Inventor: OSHIBA HISASHI
IPC: H01L21/3213
Filed: 1992-05-15
Abstract: PURPOSE:To avoid the horn growth thereby increasing the breakdown strength by a method wherein a polycrystalline silicon layer is selectively etched away to be thermal-oxidized later for the formation of a silicon oxide film on the surface of a silicon substrate and a polycrystalline silicon layer. CONSTITUTION:An oxide film 2 is formed on a silicon substrate 1; the first polycrystalline layer 3 is deposited on the oxide film 2; and then a patterned mask 4 is formed on said silicon layer 3. The polycrystalline silicon layer 3 is isotropically side-etched away in an underneath region using the mask 4 as an etching mask. Successively, the polycrystalline silicon layer 3 is anisotropically etched away to be patterned using the mask 4 as the etching mask. Next, after removing the exposed oxide film 2 and the mask 4, a silicon oxide film is formed by thermal oxidizing step on the surface of the exposed silicon substrate 1 and the polycrystalline silicon layer 3. Furtheremore, the second polycrystalline silicon layer is deposited on the silicon oxide film. Through these procedures, the defective breakdown voltage of the multilayer wiring can be corrected.

Title: Air by-pass valve
Inventor: OKUYAMA SHINGO
IPC: F02M23/04
Filed: 1978-10-04
Abstract: PURPOSE: To arbitrarily set timings of supplying air to the air intake system and stopping the supply of secondary air to the air exhaust system in an engine and to control it with one element.  
     CONSTITUTION: Both diaphragm chambers 4, 5 to which intake vacuum is supplied from an engine through a vacuum conduit 8 are equal at their pressure at normally operating time. A diaphragm 3 is biased upwardly by a spring 6, and a second valve body 18 is brought into contact with a valve seat 21 to thus close the valve and to open a valve seat 20 to thereby supply air from an air supply port 22 through a secondary air port 24 to the air exhaust system. When the engine is decelerated, increased intake vacuum is supplied directly to the chamber 5 and through a delay valve 9 in delay to the chamber 4. Accordingly, the diaphragm 3 is lowered against the spring 6 to thus cause the valve body 18 to be separated from the valve seat 21 and to also supply the air to an air bypass port 23.

Abstract: PURPOSE:To immediately cope with the changes of both the recording time point and the recording contents by performing the dynamic addition, deletion, etc., of said time point and contents during the operation of a recording control system. CONSTITUTION:A recording element register means 2 inputs the addition/deletion change instruction, the recording time point and the type of data received from an input means 1 to a recording element register area 3. At the same time, a recording start means 4 decides whether the data to be recorded exist or not based on the contents registered in the area 3 with a recording request inputted from a recording procedure 10. If said data exist, a recording data extracting means 5 is started. The means 5 reads the data out of a recording subject area 6 based on the type of the data registered in the area 3 and write the data in sequence into a recording data composing area 7 to compose a single recording output unit. An output means 8 is actuated by the means 5 and outputs said recording output unit.

Title: Wet tissue

Filed: 1990-05-16
Abstract: PURPOSE:To obviate the generation of malodors by hydrogen sulfide by further incorporating copper ions into the impregnating liquid in a nonwoven fabric of rayon as a blank material in which a sulfur component remains and the wet tissue impregnated with the impregnating liquid contg. a hydrogen component. CONSTITUTION:Since the nonwoven fabric of the rayon is used as the blank material like heretofore, the carbon sulfide used in the production process thereof remains therein. A copper compd. is further incorporated into the soln. prepd. by dissolving chemicals of a benzoic acid compd., alcohols and quaternary ammonium salt into refined water like heretofore as the impregnating liquid. Copper sulfate, copper nitrode, cuprous chloride are exemplified as the copper compd. Then, even if the carbon sulfide (CS2) remaining in the non-woven fabric of the rayon as the blank material and the hydrogen component (H2) in the impregnating liquid react to form the hydrogen sulfide (H2S), this hydrogen sulfide (H2S) reacts immediately with the copper component of the copper compd. in the impregnating liquid and forms the compd. (CuS) of sulfur and copper. The generation of the malodors by the hydrogen sulfide (H2S) is, therefore, obviated and the chemically stable wet tissue is used.
