摘要： A multi-bus semiconductor device and a method of its probing test perform the DC test for individual pads of a device while dealing with an adequate number of devices for simultaneous measurement based on the scheme of input/output pad number compressive test. The semiconductor device includes switch elements SW0-SW4 connected between input/output pads P0-P4 and a testing line L0 so that pads in an arbitrary combination, among the off-probe pads P1-P4 that are not made in contact with the tester probe Pr0, are selected for testing in correspondence to the combination of switch elements that are turned on. The input/output buffers of the pads under test are deactivated to block their internal current paths. The corresponding switch elements are turned on to connect the off-probe pads under test to the probe pad P0 that is made in contact with the tester probe Pr0, and the leak current of the probes is measured with the tester TS.

摘要： An electrical circuit device includes a controller, drivers, and a case. The controller inputs driving signals to the drivers. The drivers have multiple semiconductor relays that turn on and off power supply to electrical loads based on the driving signals. The drivers are housed in the case. The driving signals are transmitted from the controller to the drivers via serial communication. With this configuration, the number of communication lines and the communication connectors and the size of the electrical circuit device are small with respect to parallel communication. When another driver is added, only software modification of the controller and addition of a serial communication line between the controller and the driver are required. Thus, the electrical circuit device can be easily modified for different models of vehicles.

摘要： A spinning solution of an acrylonitrile polymer is subjected to dry-wet spinning through an annular type spinneret having a non-perforated part, i.e. a part not formed with spinning orifices, extending from the outer periphery to the inner periphery. The spinneret has more than 3,000 spinning orifices, at the perforated part of the annular portion. The extruded fibers are then passed through a coagulation bath, and the coagulated fibers are then stretched. By this method, uniform acrylic fibers can be produced without causing quality unevenness and fiber defects due to uneven coagulation, filament agglutination, and fluctuation of the gap between spinneret lower surface and liquid surface of the coagulation bath.
