Title: Semiconductor device incorporating complementary field effect transistor
Inventor: TSUBOTA TOSHIO
IPC: H01L27/092
Filed: 1984-01-24
Abstract: PURPOSE:To elevate the latchup-withstanding voltage of a C-MOS device by a method wherein an N<-> type region is provided in contact with P<+> type drain and source regions on the substrate when transistors of the N-channel and P- channel types are built into a complementary MOS device on a single semiconductor substrate. CONSTITUTION:An N<-> type diffused region 17 is formed in an N<+> type Si substrate 1 by means of ion injection or the like, and P<+> type drain and source regions 2, 3 are formed by diffusion in the region 17, encircled by the substrate 1 and region 17. Accordingly, the base region of a horizontal P-N-P transistor Qp1 constituting a latchup-causing parasitic thyristor comes to be located in the vicinity of the regions 17, 3. This means that the input of positive noise currents into an output terminal 15 results in the injection of holes into the base region 7 of a transistor Qn1. This accumulation of holes causes electrons to travel from the N<+> type source region 6 to the region 7 through a junction J1. Electrons flowing out into the substrate 1 are absorbed by a power source VDD through the N<+> type region 4, which elevates the latchup-withstanding voltage of the device.

Abstract: PURPOSE: To enable the connection loss of optical fibers and near-end measurement to be readily performed non-destructively by radiating the connection part and its vicinity of optical fibers and measuring the intensity distribution of the scattering light thereof in the axial direction of the optical fibers.  
     CONSTITUTION: The optical fiber 1 whose outside dimaeters and in-fiber refractive index distribution have become irregular owing to the connection part 2 such as by fusion connecting method or the like is fixed at a fixing base 11 and is moved at a constant speed by a moving device 12. This is the apparatus of providing optical fibers 13 and 14 on the same axis perpendicularly intersecting with this optical fiber 1 within the same plane, radiating the light from an LED light source 15 to the optical fiber 1 and directing the scattering light thereof to a photo sensor 16. As the fiber 1 moves in the axial direction, the intensity of scattering light changes and it turns out that as the change thereof is larger the connection loss at the connection point 2 and its vicinity is larger. Hence, by measuring the intensity distribution of this scattering light, the connection loss may be obtained.

Inventor: BREHOB DIANA DAWN
IPC: F01N3/20
Filed: 1999-01-20
Abstract: PROBLEM TO BE SOLVED: To improve fuel economy as controlling the exhaust quantity of NOx by judging the operating state of a catalyst in deceleration, and intermittently feeding an engine with fuel on the basis of the operating state so as to reduce an amount of oxygen excessively absorbed as the intermittently fed fuel reacts in the catalyst. SOLUTION: In a controller 12, a fact of whether an engine is in such a state that it is in a decelerating mode and its continuous fuel supply is temporarily stopped or not according to an engine operating state detected by various sensors is judged. Next, engine speed or air flow rate extending over the specified period of time is integrated, whereby an amount of oxygen absorbed in a catalyst 37 is judged. In the case where this absorbed oxygen quantity is compared with the specified level, this oxygen absorbing capacity exceeds the specified level, fuel is intermittently fed to the engine 10, and thereby the intermittently fed fuel reacts to reduce the excessively absorbed oxygen. Or in the case where temperature in the catalyst 37 reaches to a specified temperature, a fuel supply is intermittently carried out.

Title: Power mos transistor controlled by device having symmetrical two charge pump
Inventor: MITSUSHIERU BAROO
IPC: H03K17/06
Filed: 1990-01-23
Abstract: PURPOSE: To remove pulses generated from two charge pumps which alternately operate by combining the charge pumps with each other and smoothing gate currents from the charge pumps by means of a current mirror circuit. CONSTITUTION: Charge pumps P1 and P2 alternately operate and a voltage V(H) is not interrupted, but maintained at a value higher than or equal to the voltage at a gate GP. Accordingly, a current IG continuously flows. Because of a current mirror circuit M, the current IG is maintained constantly and does not form a pulse even when the circuit M and, furthermore, capacitors 11 and 11-1 are abruptly charged or discharged. Therefore, the problem which is raised by the charge and discharge of the capacitor between the gate and source of a transistor in the output section of an amplifier does not occur.

Thus the data 12 read out of the memory 11 is inputted to a parallel/serial converter 30. The data 12 inputted to the converter 30 consists of 8 or 16 bits, for example, and the converter 30 converts the parallel data of 8 or 16 bits into the serial data. This serial data is sent to a serial interface 15 based on the clock received from the part 13.

Filed: 1987-01-23
Abstract: PURPOSE:To enable measurement of resistance of a resistor through which flows a large current as AC with a low frequency, by determining a resonance current generated in a high frequency series resonance circuit by a voltage generated in a current measuring resistance. CONSTITUTION:In a measuring circuit 10, a secondary coil L of a high frequency transformer 11, a capacity C1, a contact resistance DELTAR of a weld part 3 and a shunt resistance for measuring current are connected in series to form a resistance measuring circuit 10 based on a series resonance circuit.

Filed: 1981-01-30
Abstract: PURPOSE:To enable density control without releasing a density controller when high or low density is needed, by forming a target composed of plural segments of liquid crystals, and selectively blackening it in accordance with set density. CONSTITUTION:A liquid crystal target T is composed of a larger segment (a), and smaller segments (b), (c), and fixed to a platen 14. A density detection sensor 46 is arranged downstream from a developing device 36. In normal copying, the segments (a), (b) are blackened, a toner density obtained from this latent image is detected and the density is controlled with a controller 50. When a high density copy is needed, only the segment (a) is blackened and developed, but the target image is composed of only the segment (a) so it is small, the detection density does not become extremely high, and the desired high density image is obtained. When a low density image is needed, the segments (a), (b), (c) are blackened. As a result, density can be controlled without separating the density controller.
