摘要:
A power supply control method of a production system including a first unit and a second unit includes: starting power supply for operation of the second unit in accordance with a signal acquired according to an operation status of the first unit (S41); starting the operation by the second unit after the start of the power supply (S44); acquiring stop time information indicating time from when the operation ends to when a next operation of the second unit starts (S22); determining, based on the acquired stop time information, whether or not to stop the power supply after the started operation ends (S24); and stopping the power supply when it is determined to stop the power supply (S48).

An anticorrosive pigment composition containing neither any heavy metal harmful to the environment nor zinc, which may be harmful to the environment. The composition is a product of the reaction of (a) aluminum dihydrogen tripolyphosphate, (b) a calcium compound selected among oxides, hydroxides, and carbonates, and (c) a magnesium compound selected among oxides, hydroxides, and carbonates. The composition exerts no adverse influence on the storage stability of water-based anticorrosive coating materials.

A server stores original data without a water-mark. When a user at a terminal apparatus connected with the server requests the server to display the original data on a display of the terminal apparatus, the server transforms the original data into an image data. Then the server adds a water-mark to the image data and transmits the image data with the water-mark to the terminal apparatus.

Provided is an electronic document management system which sorts out and stores electronic documents automatically. The electronic document management system displays the management names on a console panel of an image scanner, which are associated with document management information and pre-stored in an electronic document management server. When a user selects a given management name, an electronic document is processed in accordance with the management method associated with the selected management name. This allows electronic documents to be sorted out and stored automatically in accordance with the management method desired by a user, without the necessity of using any identification document.
摘要:
A method of producing a semiconductor device by dividing a semiconductor wafer into separate pieces of semiconductor chips. This method includes forming a groove with a pattern according to an outer contour of a desired semiconductor chip, holding the semiconductor wafer by a wafer holding mechanism, grinding a back surface of the semiconductor wafer held by the wafer holding mechanism, detecting opening of a bottom face of the groove during the back surface grinding process to determine timing for finishing the back surface grinding. The opening of the groove can be detected by means of a light sensor for detecting light passing through the groove or a microwave sensor for detecting a microwave passing through the groove. In addition, it is possible to suck air inside the groove so as to detect the opening of the groove by a pressure rise in the air inside the groove.
摘要:
An electronic device comprising a semiconductor chip which is fixed to the mounting face of a wiring board through an adhesive and in which external terminals are electrically connected with electrode pads of the wiring board through bump electrodes. Recesses are formed in the electrode pads, and in the recesses the electrode pads and the bump electrodes are connected. The electrode pads are formed over the surface of a soft layer, and the recesses are formed by elastic deformation of the electrode pads and the soft layer.

For manufacturing a packaged semiconductor device, a lead frame with an electrically insulating strip member and a semiconductor chip is placed in a molding unit having upper and lower dies. The upper and lower dies have recessed areas for determining a size of a cavity of the molding unit different from each other, the size of the cavity being measured in a direction perpendicular to a clamping motion direction of the dies. The lead frame is positioned so that a surface of each lead with the insulating strip member applied thereto is contacted with one of the upper and lower dies having a larger recessed area and a molding line of the molding unit intersects the insulating strip member. The molding unit is closed to clamp the lead frame to depress and thrust into spaces between adjacent leads that part of the strip member which is outside the molding line and to form the cavity of the molding unit. By injecting a molding material into the cavity, a molding package is provided encapsulating the semiconductor chip and a portion of each lead. The packaged semiconductor device has a flanged side surface with an insulating strip provided between a step of the flanged side surface and intermediate portions of the leads which are between first portions of the leads encapsulated in the molding package and second portions of the leads protruding from the flanged side surface.

摘要:
A distribution server and includes a communicator that communicates with multifunction apparatuses via a network a menu generator that generates menu information based on information obtained by the communicator, the information including display capability information and job capability information for each multifunction apparatus. The menu information includes information for execution of a job and a menu name assigned for the job. A data memory stores the generated menu information and a distributor retrieves, from the data memory, menu information requested by the multifunction apparatus and distributes, via the network, the menu information to the requesting multifunction apparatus.
