Patent EP-0472357-A2 (EP)
Inventor: TANINO NORIYUKI
IPC: H01L21/822
Filed: 1991-08-14
Abstract: A semiconductor integrated circuit includes a field effect transistor which is produced on a dielectric substrate, a rear surface electrode which is produced on a rear surface of the dielectric substrate, a gate bias bonding pad for applying a bias to a gate of the field effect transistor, a current path which is produced between the pad and the gate, impedance matched with the gate, and a via-hole for connecting a source or a drain of the field effect transistor with a rear surface electrode. Further the current path and the rear surface electrode are electrically connected with each other by an auxiliary current path which comprises high resistance material that does not change the impedance at the gate. Thus, static electricity charged to the gate bias bonding pad or the capacitor constituting the gate bias circuit in the fabrication process flows not through the gate of the FET but through the auxiliary current path, whereby the gate can be protected from the electrostatic breakdown.

Abstract: A tissue excision catheter system is described, e.g. an atherectomy catheter, that is capable of creating an opening through obstructing tissue in a blood vessel that is greater than the outside diameter of the catheter. The system comprises the combination of:
     (i) a catheter sub-assembly (10) carrying at its distal end a cutting head (30) that can be inserted through the plaque and then retracted so as to excise the obstructing tissue by means of a rearwardly directed cutting edge (32a), and   (ii) and inflatable cuff (22) that can be placed around the limb and inflated so as to compress the blood vessel at the site of the obstruction during the excision of the obstructing tissue. Following that excision the pressure is released so that the blood vessel expands back to its normal diameter, thereby creating a passageway through the tissue that is greater than the diameter of the cutting edge. Preferably the catheter sub-assembly comprises a central member (45) that is stationary relative to the cutting head and which determines the extend of collapse of the blood vessel under the applied pressure thereby to determine the precise thickness of the layer of tissue removed by virtue of the radial distance of the cutting edge (32a) from the stationary member (45).

Abstract: A manufacturing method of a thin film transistor consists of the steps of depositing an active semiconductor layer, a gate insulating layer, and a gate electrode on a transparent glass substrate in that order, forming source and drain regions by doping impurities into the active semiconductor layer according to an ion implantation method while functioning the gate electrode as a mask against the impurities, oxidizing a side portion of the gate electrode according to an anodic oxidation processing to form an anodic oxidation layer made of an insulating material, depositing a layer-insulation layer on the gate electrode and the anodic oxidation layer, and connecting source and drain electrodes to the source and drain regions. A channel region not doped with the impurities is formed in the active semiconductor layer between the source and drain regions, and an off set region positioned just under the anodic oxidation layer is formed in a portion of the channel region adjacent to the drain region. Therefore, an off current flowing from the drain region to the source region is decreased in a backward bias condition because of the off set region, so that a picture signal can be stored in the thin film transistor for a long time.

Abstract: This invention relates to personal computer systems and, more particularly, to such a system having security features enabling control over access to data retained in such a system. This invention contemplates protecting a personal computer system which has the capability of becoming a secure system from being placed into that condition by an attack on an unsecured machine. Additionally, in a network environment, it is important to maintain network security that any given particular system be uniquely identified to the network, in order to guard against the substitution of an insecure "alternate" which would open the network to attack through an insecure system. This invention contemplates provision for such identification in a secure manner.

Abstract: An infrared gas analyzer (15), which is adapted to miniaturization, includes a source (36) for emitting infrared radiation along an optical path, a detector (50) positioned in the optical path to detect the radiation and produce a detector output, and a sample chamber (32) positioned in the optical path between the source and the detector for containing a sample gas including the component gas to be detected. The source includes an infrared emitter that is enclosed within a gas-impervious envelope (48) that is void of reactive gases. The source is a conventional incandescent light source that is operated at 50% of rated voltage in a continuous, non-chopped manner, with all of the radiation being directed through the sample chamber. The source is optically coupled directly with the sample chamber in order to avoid the reflection of infrared radiation back toward the source. A control is provided for controlling the source and processing the detector output to a component gas indication. The control processes the detector output continuously to the component gas indication with a response time of less than 250 milliseconds. The control also processes the detector output to a component gas indication independent of any reference signal.

Abstract: The present invention relates to a device that controls the injection start time of a fuel injection pump which, when the timing control valve drive duty ratio shifts toward the most delayed angle side (0%) as the engine rotation slows down and the timing piston position has reached the most delayed angle position before the duty ratio reaches 0%, fixes the duty ratio at the value at the time point at which the timing piston position has reached the most delayed angle position. Or, it stores in memory the value at the time point at which the timing piston position had reached the most delayed angle position and sets the duty ratio at 0%. If the engine rotation rate increases suddenly, it shifts the duty ratio from the duty ratio at which the timing piston has reached the most delayed angle position so that the actual timing piston position immediateiy follows the target timing piston position. It correctly processes the deviation between the timing piston position and the duty ratio when the rotation rate is low, thus reducing the tendency toward trailing delay in the injection timing when the engine rotation rate increases from low speed.

Abstract: A character pattern generation apparatus generates a character pattern on the basis of font data in a stroke format. A data generation unit generates character data, character element data, or stroke data on the basis of the font data in the stroke format. A storage unit stores the character data, character element data, or stroke data generated by the data generation unit. A discrimination unit discriminates if character data, character element data, or stroke data corresponding to a character pattern to be generated is stored in the storage unit. When the discrimination unit determines that the character data, character element data, or stroke data corresponding to the character pattern to be generated is stored in the storage unit, a character pattern generation unit generates the character pattern on the basis of the character data, character element data, or stroke data stored in the storage unit.
