An apparatus for measuring a figure distance between first and second points of a solid figure with a measuring device having first and second panels and an axis connecting the panels is provided with a measuring device data storing section for storing attribute data and constitutional data of the measuring device, a solid figure data storing section for storing solid figure data, and a display section for displaying the measuring device and the solid figure according to the data stored in the storing sections, a moving section for positioning the first and second panels at the first and second points according to a motion mode, and a renewing section for renewing the data according to an editing mode. In the moving section, the axis is extended or shortened, translation movement is performed for the measuring device, and/or the panels is deformed in a stick shape according to the motion mode. In the renewing section, the measuring device is rotated or jointed to a second measuring device, one of the panels is overlapped with a surface or an edge of the solid figure, and/or the axis is curved to measure a curved outline length of the solid figure according to the editing mode.

A semiconductor integrated circuit device such as a memory device with logic function comprises a plurality of RAM macrocells and gate arrays. The RAM macrocells are constituted by bipolar CMOS RAMs having a total memory capacity of at least 100 kilobits, and the gate arrays contain at least 4000 gates. The logic circuits in the memory device with logic function or the like are constructed by selectively combining CMOS, bipolar CMOS or ECL gate circuits depending on the output load capacity, transmission characteristic requirement, power dissipation and required layout area. The level of signals at various circuits is set to the ECL level or MOS level depending on the local circuit configuration and other factors. The memory device further incorporates sequence control circuits required to be installed downstream of buffer storages of computers.

摘要:
A wheel bearing assembly for an automotive wheel equipped with a detector for the number of revolutions of a wheel hub. It has an outer member and two inner members mounted in the outer member through rolling elements. A pulse ring in the form of a multipolar magnet is mounted in the bearing assembly so as to be fixedly held in annular grooves formed in the outer periphery of the inner members at their abutting ends or to be supported on one of the inner members. A sensor including a Hall IC is mounted in the outer member at such a position as to face the pulse ring. The pulse ring rotates with the inner members to allow the sensor to detect the rotational speed of the wheel.
摘要:
An input/output control system includes an external data controller connected to a plurality of input/output units, a central processor, and a main storage accessible from the external data controller and the central processor. The main storage has a storage area corresponding to each input/ouptut unit and a storage area storing information to arrange a queue for a plurality of priority classes for determining the start priority of each input/output unit. At execution of a start instruction, the central processor sets a control information of the input/output unit to an associated storage area of the main storage and updates the queue arrangement information. The external data controller starts an input/output unit registered to a queue having the highest priority. The start operation is achieved according to the control information of the input/output unit stored in the main storage.

摘要:
A signal value representing at least one of a plurality of types of optical characteristics are calculated for each pixel from the read signal obtained and output by reading light reflected by a document placed on a document table and a document table cover while the document is covered with the cover. It is determined, based on the signal value calculated, whether or not a target pixel is a pixel in a document region. A document region is detected from the determination result.
摘要:
A waiting time Ts is decided on the basis of ink type information and ink feed amount information, referring to waiting time table A (Step 6). Along with this, a dried printing paper is carried to and stopped in a waiting area 9 (Step 7), a time period T is measured after stopping, and measurement processing in the next step is delayed until the time period T reaches the waiting time Ts. Then, when the time period T reaches the waiting time Ts, a measuring instrument 10 is used to measure a density of a patch printed on the printing paper (Steps 8 and 9).
