In order to improve the robustness against electrostatic discharge, when power source terminal and ground terminal are open, of a semiconductor device having a first, a second and a third inverter that are connected in a cascade arrangement, the semiconductor device is provided not only with a first input protection circuit for guiding positive electrostatic discharges, that are applied from outside to a signal input terminal, to a power source line, and a second input protection circuit for guiding negative electrostatic discharges, that are applied from outside to the signal input terminal, to a ground line, but also an internal protection circuit for guiding electrostatic discharges that have been guided by the first input protection circuit to the power source line and flow from a P-channel MOS transistor in the second inverter towards the third inverter, to the ground line.

With keeping an atmosphere including oxygen within a chamber and with a wafer kept at a low temperature, plasma generated within the chamber is biased toward the wafer, and the wafer is subjected to the plasma. A semiconductor layer exposed on the wafer is oxidized into an oxide film. Thus, an oxide film can be formed even at room temperature differently from thermal oxidation. This oxidation is applicable to recovery of an implantation protection insulating film having been etched in cleaning a photoresist film, relaxation of a step formed between polysilicon films, relaxation of a step formed within a trench and the like. Also, before removing a photoresist film used for forming a gate electrode including a metal, a contamination protection film can be formed by this oxidation with the photoresist film kept.

An information processing method includes the steps of: obtaining, among arithmetic instructions, information on data sets referred to by memory reference, and assigning to different banks a plurality of data sets simultaneously referred to by memory reference performed in accordance with an arithmetic instruction. This allows bank assignment to be performed automatically without causing memory bank conflict.

A reference signal frequency is generated for selection of a desired channel by a frequency sweep circuit comprising two sweep oscillators. The operations of the oscillators are reversed with each other at a predetermined frequency interval, and a voltage sweep main circuit and a voltage sweep sub-circuit are provided to apply a control voltage to a variable capacitance diode. The diode is contained in a tuner to control the sweep operation by the voltage sweep circuits in response to the reference frequency for channel selection.

摘要:
An apparatus for simultaneously reading images on both sides of the document sheet as the sheet having images on both sides is moved through the apparatus, one side read by a CCD sensor and the other side read by a contacted image sensor. An image synthesizing unit synthesizes image data from the CCD sensor and image data from the contacted image within one cycle of main scanning by the two image reading units. Furthermore, image processing circuits in the subsequent steps perform specific modes of processing on the data within one cycle of main scanning. That permits simultaneous reading of both sides of the sheet document without reducing document reading speed and expansion of the image processing unit.

An automatic gain control circuit has two rectifiers and a variable impedance element to which the output of the rectifiers is applied so as to obtain the gain control operation. One of the two rectifiers has a fast attack time, and controls the variable impedance element when the input signal increases suddenly, and the other one controls the variable impedance element for the time other than the time when a sudden change of the input signal is occurring, so that there is no overshoot in the output signal even through the input signal increases suddenly.

A high voltage transformer device in a horizontal deflection circuit supplying an extra high tension (EHT) to the anode of cathode-ray tube, which comprises a low-voltage coil (primary winding) and a high-voltage coil (secondary winding) including a high-voltage side winding and a low-voltage side winding, wherein the high-voltage side winding of the high-voltage coil is more closely magnetically coupled to the low-voltage coil than the magnetic coupling between the low-voltage side winding of the high-voltage coil and the low-voltage coil, thereby suppressing variations of the high voltage output, and improving the trackability of the focusing voltage when a focusing coil is additionally provided.
