摘要:
The collector, emitter, and base of a bipolar transistor circuit are connected to a high side power supply terminal, the drain of a level shift transistor, and a floating power supply terminal, respectively. When a high side output transistor is on, the floating power supply terminal is at the potential of a high potential power supply terminal. The high side power supply terminal is at a potential higher than the potential of the floating power supply terminal by a constant voltage. Turning the level shift transistor on, its drain potential drops below the potential of the floating power supply terminal; The base current flows through the bipolar transistor circuit and the drain potential of the level shift transistor is clamped near the potential of the floating power supply terminal; The bipolar transistor circuit is turned on and its collector current supplies the drain current of the level shift transistor.

A semiconductor integrated circuit device capable of securely preventing the output from becoming indefinite even when power is turned ON or OFF or even in a transient state in which the power voltage varies abruptly. In the semiconductor integrated circuit device, a protection circuit compares the power voltage from a first power supply terminal with a reference voltage, detects power ON, power OFF and abrupt power voltage variation, and outputs a reset command signal so that the output at the output terminal has a high impedance at the time of power ON, power OFF and abrupt power voltage variation.

A testing method of semiconductor integrated circuit wherein the quality of diffusion for semiconductor chips can be tested before the semiconductor chips become packaged semiconductor integrated circuits is provided. Input data is set, and circuit current values I(L) and I(H) obtained for each of a plurality of circuit areas are compared with first test pass ranges I1(L) and I1(H) to extract articles within the first test pass (S2), and the current values of the circuit areas determined to be articles within the first test pass and second test pass ranges I2(L), and I2(H) determined based on these current values are compared, thereby conducting a retest to extract circuit areas within the second test pass. The current values may be replaced by the voltage values.

An image reading system prescans and/or scans a film with magnetic recording and image data to be stored in a film cartridge after the film is developed. The image reading system employs a one-dimensional CCD and is capable of recording/reading retrievable ID numbers on a magnetic recording part. A thumbnail display simultaneously displays all image and magnetic information of all frames of a film, and selected frames to be scanned can be easily identified and compared after obtaining the image data of such film through prescanning. Magnetic recording-information and image information are rapidly read during prescanning and selected frames are then scanned with more refinement as compared to the coarse scanning of the film during prescanning.

A transporting system for an image digitizer can handle both positive and negative transparent film material. The transport features accurate linear motion with high resolution in a single compact unit. For the processing of individually framed slides, an automatic eject mechanism is provided. Both manual and motor driven focus adjustments are provided. Individual images can be oriented by an angular adjustment option. A special carrier allows the system to process negatives in uncut strips. The transport can manage larger number of images using either a slide tray or roll feed attachment.
