Title: Sheet frit, vacuum vessel sealing method and manufacture of image display device
Inventor: UDA YOSHIKI
IPC: H01J29/86
Filed: 1994-07-08
Abstract: PURPOSE:To provide a method by which sealing can be reliably performed with excellent productivity in the case of manufacturing a large vacuum vessel, particularly, a plate type image display device, and a sheet frit suitable for this method. CONSTITUTION:A sheet frit by temporarily baking frit glass after it is molded into a sheet-like small piece is used as a sealing material. Engaging parts, that is, step difference parts 101a and 104a or groove parts 102a and slant face parts 105a and 106a are arranged on sheet frits 101 to 106. Plural sheet frits are arranged in a sealing part so that the engaging parts engage with each other, and sealing is performed by heating. When paper strip-shaped sheet frits having no engaging part are used, the sheet frits are arranged by two or more layers or by two or more rows in the sealing part so that sheet frit end parts are dislocated from each other.

Title: Electric discharge device
Inventor: ITAYA RYOHEI
IPC: H05B41/392
Filed: 1992-05-01
Abstract: PURPOSE:To facilitate the practical use of a discharge device for a variable color by controlling a luminescent color from one discharge tube through using a quite common power source like a sine wave or D.C. CONSTITUTION:In the glow discharge of low-pressure gas, the electric field of a negative electrode lowering part easily becomes larger than a positive column portion, and also the luminous colors of both sides easily becomes different. A negative glow is generated in an electrode inner surface along a tube wall by injecting A.C. power by capacitance coupling from an electrode installed in a tube wall outside to utilize the difference of the luminous color of the negative glow from that of a positive column. For example, two sets of electrode pairs 3 and 4 are provided on a discharge tube enclosed with gas different in a luminous color and an excitation level like neon and mercury, and at least one side 4 of the sets is installed along the tube outer wall. A.C. voltage is applied to this electrode pair to generate negative glow in the inner wall of the electrode pair. The other side electrode pair can be of any type as long as generating a positive column and can be regardless of the A.C. or D.C. and frequency of a power source.

Filed: 1995-05-31
Abstract: PURPOSE: To obtain OTA capable of executing a low voltage operation whereby the linearity of transconductance is improved over a wide input voltage range which is generated in a semi-conductor integrated circuit. CONSTITUTION: The transconductance of a differential pair 101 is reduced in accordance with the increase of an input voltage VIN. When the differential pari 10-1 is a bipolar differential pair Q1 and Q2 which is driven by constant current by commonly being connected to an emitter, the collector current Ic1 of a transistor Q1 is turned back at a first current mirror circuit 103 and taken- out as differential output current ΔIc. When a square characteristic is given to the driving current IEE of the transistors Q1 and Q2, the linearity of the transconductance is improved. Then, current I<-> being one of the differential output currents of a square circuit 102 is permitted to flow in the constant current source of the differential pair 101 so that the effective driving current IEE of the differential pair 101 becomes the one obtained by subtracting I<-> from current IT.

Abstract: PURPOSE:To certainly detect the presence of a human body by a method wherein a self-diagnosing part is provided to detect an infrared detection element not operated normally among a plurality of ones and the presence of the human body is judged on the basis of the detection signal by the normal detection element. CONSTITUTION:The infrared rays condensed by an optical system are received using an infrared detection element part 2 consisting of a plurality of infrared detection elements A-D and the outputs of said elements are amplified by an amplifying part 3 and processed by a signal processing part 4 to judge the presence of a human body by a judging part 5. When the infrared detection element falling into an abnormal state by trouble is present, said element is detected by a self-diagnosing part 7 and a signal showing which infrared detection element is abnormal (e.g., a signal showing that the element D is abnormal) is sent to the judging part 5. In the judge part 5, the present of the human body is judged using only the outputs of the remaining normal elements A to C. As mentioned above, since the human body is detected using only the outputs of the normal infrared detection elements, there is no wrong information.
