Title: Diode
Inventor: HASEGAWA FUMIO
IPC: H01L29/93
Filed: 1979-05-10
Abstract: PURPOSE:To enhance the breakdown voltage in the periphery of a Schottky junction or pn junction higher than the intermediate portion and largely vary the junction capacity with respect to bias voltage in a diode by forming a low resistance operation layer inside the region provided with the junction. CONSTITUTION:A high resistance n-type operation layer 121 is formed on a low resistance GaAs substrate 11, ion is implanted or diffused to selectively form a low resistance operation layer 122. An opening is perforated at the SiO2 film 14, an aluminum electrode 15 is formed through the opening so as to form a Schottky junction. Since the periphery 153 of the junction makes contact with the high resistance operation layer 121, the breakdown voltage is higher than the central portion 112 thereat. Therefore, the breakdown voltage of this diode is controlled by the breakdown voltage of the original low resistance operation layer including the Schottky junction mostly. The capacity-to-voltage characteristics of the diode exhibits super-stepwise characteristics controlled by the low and high resistance operation layers.

Title: Disconnection detecting method for transmission and distribution line
Inventor: ABE NORIO
IPC: G01R31/08
Filed: 1996-03-14
Abstract: PROBLEM TO BE SOLVED: To surely detect disconnection occurring in any phase of a transmission line by attaching an optical voltage sensor to arbitrary phase of a transmission and distribution line, and by connecting a power source transformer to other phase so that a power source voltage is obtained. SOLUTION: An optical voltage sensor 1 is attached to an arbitrary one phase, for example B phase, of a transmission and distribution line. A power source transformer 2 is a transformer to provide a power source voltage from two phases other than the phase where the optical voltage sensor 1 is attached, for example, while getting 100V from 6600V, supplies it as a power source for the optical voltage sensor 1. In case the B phase is disconnected, the voltage to ground of B phase drops to about a half of normal 3800V. Thus, the drop of voltage to ground is directly detected with the optical voltage sensor 1, far detecting disconnection. When either A phase or C phase is disconnected, a sensor power source 100V drops to about a half level. So, by monitoring the sensor power source obtained from a power source transformer 2 at always, disconnection is detected.

Title: Spectrophotometer for photodiode array
IPC: G01J3/36
Filed: 1992-03-16
Abstract: PURPOSE:To correct the relative shifting amount between the wavelengths of a sample detector and a reference detector by calculating the shifting amount between each wavelength, and arranging a time difference between start pulse signals of the detectors. CONSTITUTION:At the adjusting time of the wavelength, the absolute shifting amount of the wavelength of each of a reference detector 7 and a sample detector 8 is stared in a reference wavelength data part 15 and a sample wavelength data part 16. A control part 17 uses the data as the basis to form the time difference corresponding to the shifting amount of the read wavelength. Supposing that the data of the data part, 15 is -1 and that of the data part 16 is +1, the relative shifting amount is 2. Since the scanning time of a photodiode array corresponds to the wavelength, when one cycle of a scanning clock signal is (t), the video signals of the detectors 7 and 8 have the same wavelengths input to a LOG converting part 13 simultaneously if a scanning start signal for the detector 8 is output 2t later after a scanning start signal for the detector 7 is output.

Filed: 1998-03-10
Abstract: PROBLEM TO BE SOLVED: To obtain an analytical method in which the substance characteristic of a material for a thin film can be analyzed easily and in a short time by a method wherein a theoretical value and a measured value are converted into a spectrum density distribution by a maximum entropy method(MEM) in addition to the method of nonlinear least squares and to a fitting technique and the method of nonlinear least squares is applied to its image space. SOLUTION: A sample in which a single-layer or multilayer thin film is formed on a substrate is irradiated with X-rays. The substance characteristic of a material for the thin film is measured on the basis of the dependence on the angle of incidence of the intensity of their reflected X-rays. In this case, in a process in which the substance characteristic is found in such a way that the measured value of the dependence on the angle of incidence of the intensity of the reflected X-rays agrees with a theoretical value, the theoretical value and the measured value are converted into a spectrum density distribution by an MEM. The method of nonlinear least squares is applied in its image space, and the substance characteristic is found. Thereby, the substance characteristic of the material for the thin film can be analyzed easily and in a short time without depending on experience.

Title: Light emitting diode lighting device
Inventor: MORI MASAKAZU
IPC: H04B10/2507
Filed: 1986-03-17
Abstract: PURPOSE:To take out always a current from a power source to make the supply current constant by using a collector open type transistor-transistor logic integrated circuit which is connected in parallel to a light emitting diode and permits the supply current to pass through for extinction of the light emitting diode and stops the current for the control of lighting of the light emitting diode. CONSTITUTION:A collector open type transistor-transistor logic integrated circuit 13 is operated as a switching element and has always the contact closed and is connected in parallel to a light emitting diode 11 in this state. At this time, the circuit 13 permits the supply current to pass through resistances 12 and 14, and the light emitting diode 11 is not lit. When a control signal is given to the circuit 13, the contact is opened, and the voltage applied to the light emitting diode rises to give a lighting voltage, and the supply current flows through the resistance 12 and the light emitting diode 11. If values of resistances 12 and 14 are selected in accordance with characteristics of the circuit 13 and the light emitting diode, the value of the current flowing to the resistance 12 is kept at a small change independently of lighting/extinction of the light emitting diode, and the variance of the supply current is prevented.
