In a method for selling an approved material, the amounts of each material forwarded to and used by each customer are input into a computer, and the updated amount of inventory of the material in the customer is recorded. The computer checks the amounts of inventory and the used amount when issuance of an approved material certificate is requested from a customer having an ID number and a password through a network communication. When the used amount does not exceed the amount of inventory, issuance of the approved material certificate is approved, and the used amount is subtracted from the amount of inventory to update the amount of inventory. When the used amount exceeds the amount of inventory, the issuance is disapproved. When an approved material is sold and issuance of the approved material certificate is requested through a network communication, approval or disapproval is decided quickly and accurately.

A differential circuit with a function of a variable gain without shifting the output cross point is disclosed. The differential circuit includes an amplifying stage and a control stage. The amplifying stage includes three units each having a pair of transistors, a pair of load resistors, and a pair of current sources. The second and third units each put between the first unit and the load resistor to bypass the current. The control stage includes two units and two current sources to compensate the current bypassed by the second or third unit to keep the DC output level substantially in constant.

A completely-enclosed cell wherein if the internal pressure in the cell rises because of short circuit or overcharging, temperature rise and explosion of the cell is effectively prevented, the current is cut off, and the internal pressure is simultaneously and quickly released. The cell includes a sealer comprising a valve body composed of a metal substrate perforated at narrowly spaced intervals in the endless periphery and a metal foil 72 substrate to cover the perforations. The cell a structure in which a narrow gap portion of a 98 metal plate deformable even by a weak force of when the internal pressure increases elongates and the portion surrounded by the through holes projects 122.

A method of forming a protective coating on a cell safety valve element by coating the cell safety valve element with a protective film to protect metal portions thereof against corrosion, a cell safety valve element coated with a protective film, a cell sealing plate using the element, and an enclosed cell using the plate. The safety valve element comprises a coating (3) obtained by applying an organic paint onto at least one surface of the cell safety valve element (10) consisting of a metal base plate (1) having a through hole (4) drilled therein and a metal foil (2) laminated on the metal base plate (1) so as to block the through hole (4). The sealing plate is formed by bringing the cell safety valve element (10), on which a protective coating (3) comprising an organic resin film is formed, into contact with a cell exterior can sealing plate (6), in which the through hole (4) acting as a safety valve port is drilled so that the through hole (4) in the metal base plate of the cell safety valve element (10) and the through hole (7) in the sealing plate face each other and bonding the both at a portion around the through hole (7) in the sealing plate to form the cell sealing plate. The enclosed cell is formed by fitting and supporting the cell sealing plate at the inner periphery of an opening of the cell exterior can in which are housed an electrode body consisting of a positive electrode, a negative electrode and a separator together with an electrolyte to block the opening in the cell exterior can.

An electronic control unit for an automotive vehicle which can be manufactured at a low cost and which is compact in size, includes a first microprocessor which has a first memory storing one of a plurality of arithmetic programs for controlling respective predetermined control systems, and which is connected to at least one external sensor and an actuator of a corresponding one of the predetermined control systems. The first microprocessor arithmetically processes information from the at least one external sensor based on the one of the plurality of predetermined arithmetic programs stored in the first memory, and delivers a control signal as a result of the arithmetic processing to the actuator. A second microprocessor is connected to the first microprocessor to deliver and receive data to and from the first microprocessor, thereby monitoring operation of the same. The second microprocessor includes a second memory which stores both check data for checking the operation of the first microprocessor, based on which the first microprocessor executes predetermined arithmetic processing, and solutions determined by the check data. The check data is commonly applicable for all of the plurality of predetermined arithmetic programs. The second microprocessor also includes a determining block which compares between results of the predetermined arithmetic processing executed by the first microprocessor based on the check data and the solutions, and determines that an abnormality exists in the first microprocessor when the results of the predetermined arithmetic processing and the solutions do not agree.
摘要:
In a resin-coated metal sheet, at least one surface of a metal sheet 10 as a base sheet is overlaid by a transparent polyester resin film A of 5 to 100 &mgr;m thickness through a paint layer E, a modified olefin resin layer D of 5 to 100 &mgr;m thickness, a pattern or/and solid printing layer C and an adhesive layer B which layers are put one over another in order from the side of the metal sheet toward the transparent polyester resin film. Since the modified olefin resin layer which is provided in between the transparent polyester resin film and the metal sheet has the excellent adhesiveness against the printing layer, the paint layer and the polyester resin film, even if the resin-coated metal sheet is formed under the severe condition against the resin-coated metal sheet, for instance, by deep drawing, delamination does not occur so that the excellent workable adhesion strength is shown. Further, the roughness of the surface of the metal sheet, and unevenness of several component resin layers are absorbed by a modified olefin resin layer so that the excellent vivid relectivity for a resin-coated metal sheet can be obtained.
摘要:
A differential amplifier capable of canceling an input offset current and expanding a linearly operating range is disclosed. The differential amplifier, which is preferably applicable to an optical receiver to convert a photocurrent into a voltage signal, includes a trans-impedance amplifier and an offset canceller that detects output offset and extracts input current to cancel the output offset. Moreover, the extracted input current traces the average level of the input voltage to widen the linearly operating range of the trans-impedance amplifier.
