Title: Device for executing all optical switching of light signal, method for changing over light signal by using light pump md method for using sagnac interferometer loop as optical switch
Inventor: DAVIS MONICA K
IPC: G01B9/02
Filed: 1999-07-29
Abstract: PROBLEM TO BE SOLVED: To make even a long waveguide stable to a slow environmental disturbance, such as a temp. change, over the length of an arbitrary wavelength by using a Sagnac switch architecture. SOLUTION: When the pulp pulses from a pump source 420 are impressed via a second wavelength division coupler 422, different phase shifts are generated in two oppositely propagating light signals. This generation occurs in the influence of the pump signal on an active fiber 416 and the asymmetric positioning of the active fiber 416. When the differential phase shifts are ±π or odd times ±π(namely, the phase shifts of ±(2n+1)π when n=0, 1, 2,...) are assumed and the two signals interfere to weaken each other at a port A of a coupler 414 and interfere to intensify each other at a port B of the coupler 414. The output fiber 450 (port 4) couples the output signals from the port B of the coupler 414 as the changed over output signals.

Abstract: PURPOSE:To improve the high frequency characteristic and high speed operation by enhancing mutual conductance and reducing gate capacitance by deeply forming the second region, the third region, and a gate region in this order so that the second region becomes the deepest. CONSTITUTION:Si ions are implanted via a mask of photo resist 12 into one main surface of a semi-insulation GaAs substrate 11, thus forming an N type semiconductor region 13 serving as so-called a channel layer which includes a source and a drain. Next, after removing the mask 12, the substrate 11 is adhered in opposition to another GaAs substrate in H2 gas containing AsH3, and capless annealing treatment is performed. Then, an Si nitride film 14 is adhesion-formed on one main surface of the substrate 11, the part corresponding to the gate part of this Si nitride film 14 is selectively removed by the plasma etching with CF4+O2 gas via a mask of photo resist, resulting in the formation of a window hole 16. Further, a high resistant region (i.e. N type region of a low concentration) 17 is so formed as to be superposed on an N type semiconductor region 13, and a gate region 19 of the second semiconductivity type, i.e., P type is formed by selectively diffusion Zn through the same window hole 16 by the Si nitride film 14.

IPC: F02D45/00
Filed: 1986-09-13
Abstract: PURPOSE:To suppress the generation of knocking in the high load region and prevent the deterioration of fuel consumption in the low load region by increasing the reduction quantity of the combustion efficiency according to the engine load, in the control of the reduction of the combustion efficiency which is performed when the intake temperature is high. CONSTITUTION:In a controller 25, the fundamental ignition timing is determined from the intake air quantity on the basis of the output of an air flow sensor 21 and the number of engine revolution on the basis of the output of a distributor 17. Then the correction quantity IG for the ignition timing is called in from a map the basis of the intake temperature input from an intake air temperature sensor 23 and the intake charging quantity which is obtained by dividing the intake air quantity by the number of engine revolution. The correction quantity  IG is set so as to increase to the retardation side when the intake temperature is high and so as to increase in the high load region than that in the low load region. Since the final ignition timing is calculated by subtracting the correction quantity  IG from the fundamental ignition timing, the generation of knocking in the high load region can be prevented, and further the deterioration of fuel consumption due to the excessive control in the low load region can be prevented.

Title: Magnetoresistance element
Inventor: MAEDA ATSUSHI
IPC: G11B5/39
Filed: 1994-09-09
Abstract: PURPOSE: To obtain a magnetoresistance element which exhibits a larger MR ratio and has a magnetoresistance effect film having high magnetic field sensitivity by providing shape anisotropy in the grains of a ferromagnetic material. CONSTITUTION: A board 1 is coated with a mask film 2, and stripelike grooves 2a are formed on the film 2 by an electron beam lithography method. Then, when a Co-Ag alloy film is deposited by an RF sputtering method, an alloy film 3b is formed on the film 2, and an alloy film 3a is formed in the grooves 2a. Since the Co is solid insoluble in Ag, Co forms grains. Since the grains of the ferromagnetic material has shape anisotropy, the magnetoresistance change rate is increased in the specific magnetic field direction. Accordingly, a magnetic field is applied in such a direction to detect the change of the electric resistance, thereby enhancing the magnetic field sensitivity.

Filed: 1986-09-12
Abstract: PURPOSE:To simplify manufacturing processes, by forming source and drain electrode drawn-out layers in a n-channel MOS element concurrently with an emitter layer by the use of diffusion through silicon films formed on these layers. CONSTITUTION:After deposition of an oxidizing film 402, not only windows for drawing out source and drain electrodes in a n-channel MOS element are opened, but also a window at least for forming an emitter layer is opened. A silicon film of n-type high-impurity concentration is deposited, and so the opened window regions are covered by patterning and etching methods. Impurity introduction is performed through silicon films (202-204) to form a source electrode drawn out layer 12, a drain electrode drawn-out layer 13, and an emitter layer 15. Thus, manufacturing processes can be simplified because source and drain electrode drawn-out layers in the n-channel MOS transistor are formed concurrently with the emitter layer in the bipolar transistor.

Filed: 1996-07-29
Abstract: PROBLEM TO BE SOLVED: To permit accurate discrimination of the state of a film by one sensor and to reduce the cost by discriminating between an error signal and a normal signal, even when an operation becomes instable at the start of rotating a bar code disk and an erroneous sensor reading signal is generated, as for a film state discriminating device. SOLUTION: At plural stages while rotating the bar code disk, information reading sensor outputs are detected, and the inclination of a change in the sensor output is detected based on the sensor outputs obtained at plural stages and a time between plural stages. In the case the detected inclination of the sensor output is equal to or exceeding a prescribed value, the sensor output is counted as the normal signal, but, in the case the inclination is below the prescribed value, the sensor output is regarded as the erroneous signal and the output is not counted. Then, the film state is accurately discriminated based on the counted sensor output value in such a way.
