Title: Pickup device for reading optical recorded information
Inventor: MAEDA TAKANORI
IPC: G11B7/127
Filed: 1983-06-02
Abstract: PURPOSE:To obtain a high-quality focus error signal and a tracking error signal with simple constitution by arranging two light sources having astigmatism in specific positions and using these light sources to detect the position state of a detection point due to an information detecting light source. CONSTITUTION:A semiconductor laser chip 4 is provided as the information detecting light source, and semiconductor laser chips 5 and 6 are provided as light sources having astigmatism. Their optical axes 4a, 5a, and 6a of radiation are places on the same plane, and the active layers of chips 5 and 6 form 90 deg., and the light source 5 is projected from the light sources 4 and 6 by length (d), and this length (d) corresponds to the quantity of astigmatism of the light source 5. Consequently, a sagittal caustic curve ls1 of the light source 5 and a meridional caustic curve lm2 of the light source 6 exist in the same plane and are parallel with each other, and their direction (y) coincides with the recording track direction. In Fig., 4s, 5s, and 6s are irradiated spots from light sources 4, 5, and 6 respectively, and 2 is a track. When the luminous flux from the light source 4 is in focus, the shapes of spots 4s, 5s, and 6s become as shown by Fig. B; but if it is out of focus, their shapes become as shown by Fig. A and C, and a difference is generated between AC components of detection signals due to sports 5s and 6s. Thus, the focus state is detected.

Title: Conductivity modulation type mosfet
Inventor: UENO KATSUNORI
IPC: H01L29/78
Filed: 1988-04-22
Abstract: PURPOSE:To omit it to add a high-impurity concentration well layer to the center of a base layer to reduce the cost of the title MOSFET and to prevent the generation of a latch-up by a method wherein a metal which causes a sintering phenomenon with silicon is used for an emitter-source electrode and, moreover, the distance between the edge part of the contact surface of the electrode with a source layer and the edge part of a gate is limited to a specified distance or shorter. CONSTITUTION:A source layer 6 is formed on the whole region other than a channel forming region in the surface layer of a p-type base layer 4 of a second conductivity type and an emitter source electrode 9 consisting or a metal which causes a sintering phenomenon with silicon is provided in such a way as to come into contact to the layer 6 through an insulating layer of a width of 4mum or narrower between the edge parts of a gate 8. When pure Al or Ti and so on are used for the metal constituting the electrode, a phenomenon called sintering or spearing is generated and the metal penetrates the source layer and brings the base layer under the source layer into a low-resistance state. By inhibiting the distance (r) between the source layer and the end part of the gate 8 within the electrode 9 to 4mum or shorter, the base short- circuit resistance of a parasitic transistor is decreased and the process of forming a high-impurity concentration well layer can be omitted.

Title: Method for channel scanning.
Inventor: SCHELLINGER MICHAEL J
IPC: H04B7/26
Filed: 1995-12-14
Abstract: A unique method improves channel scanning by reducing the time required to scan channels. The method reduces the number of channels which must be scanned using information previously obtained in a scan. If two sets of channels which overlap are scanned in two separate scanning steps (522), information obtained in a first channel scan can be used, thereby eliminating the time required for a second channel scan. For example, if the dedicated control channels and the paging channels of a cellular telephone system overlap, the channels which overlap need not be scanned during the channel scan of the paging channels. The method further reduces scanning time by encoding the channel scanning of a particular channel if an undesired channel type is detected (808).

Abstract: Video magnification apparatus modifies (shrinks or enlarges) video graphic images in a horizontal and vertical direction during a transfer of video graphics data signals from a graphics memory to a television screen. A first magnification modifying device modifies the magnification of a graphic by a vertical magnification factor by generating graphic line address output signals that selectively prevent a transmission of predetermined horizontal lines of the graphic upon the reception of a vertical magnification factor that is less than unity. A second magnification modifying device is responsive to the transmissions of the horizontal lines of the graphic indicated for transmission by the output signals of the first magnification modifying means for modifying the magnification of the graphic in a horizontal direction by a horizontal magnification factor.

Title: Method and apparatus for fault detection and correction in coriolis effect mass flowmeters.
Inventor: CARPENTER BRENT LEE
IPC: G01N11/04
Filed: 1995-07-24
Abstract: Apparatus and methods for detecting and correcting various fault conditions in an operating Coriolis effect mass flowmeter. The present invention receives information from an operating Coriolis mass flowmeter and compares the information to threshold signatures representing various fault conditions. When a fault condition is dectected, output signals are applied to inform an operator and to control the mass flow rate through the flowmeter to correct the fault condition. Specific methods of the present invention detect the presence of a crack in the flow tubes and stop the flow of material to prevent release of the material through cracked flow tubes. Other methods of the present invention detect the void fraction of material flowing through the flow tubes, compute a corrected actual mass flow rate, and control the mass flow rate through the flowmeter to compensate for the effects of the void fraction.
