Title: Luminescence spectral analysis method and its device
IPC: G01N21/62
Filed: 1992-03-26
Abstract: PURPOSE:To quantitatively analyze constituent elements in individual existence configurations by judging that compounds of constituent elements and nonconstituent elements exist in specific sample areas by luminescence contained at the preset level or above. CONSTITUTION:High-voltage pulses are applied to a counter electrode 4 from a discharge circuit 2. Spark discharges are repeated between a sample 3 and the electrode 4 several thousand times, and the luminescent line intensity of each element at each discharge is measured.

Title: Fluorescent lamp lighting device
Inventor: KOMATSU HARUKI
IPC: H05B41/392
Filed: 1995-02-17
Abstract: PURPOSE: To enable lamp current to be controlled according to lamp voltage by providing a means for varying a lighting frequency according to the lamp voltage of a fluorescent lamp, and varying the lighting frequency so that when the lamp voltage is in a stable low state, lamp current flows by a smaller amount than under normal conditions. CONSTITUTION: A circuit consisting of a transistor 24 and a resistance 28 varies a current passed through a transistor (Tr) 24, depending on the differential voltage between the voltage VL at each end of a capacitor 23 and a voltage VR, thus controlling an oscillating frequency; i.e., a collector current IC flowing through the Tr 24 becomes IC=CVR-VL)/R28 ×hFE. Therefore, when the lamp voltage VLP of a fluorescent lamp 6 is great, the VL is also great, and the collector IC becomes smaller. When the lamp voltage VLP of the fluorescent lamp 6 is small, the VL is also small, the collector IC becomes greater, and the combined resistance of the R terminal becomes R=R27 //(VR/IC). Therefore, controlling the lamp current according to the lamp voltage EVLP is made possible.

Title: Manufacture of semiconductor substrate
Inventor: KURIYAMA HIROKO
IPC: H01L21/322
Filed: 1985-04-01
Abstract: PURPOSE:To make it unnecessary to conduct a fixation process for interstitial oxygen, i.e. an I.G. treating process, which is required for a CZ substrate, by a method wherein an FZ substrate wherein the concentration of the interstitial oxygen is below the deposition concentration is annealed at a specified temperature or above, after implantation of nitrogen, so as to form an epitaxial layer. CONSTITUTION:A semiconductor substrate formed by a floating zone method (an FZ substrate) being used, nitrogen is implanted in the FZ substrate 2 at an acceleration voltage 100KeV and in a dose quantity 2X10<11>cm<-2>, and further a heat treatment is applied for 30min, at a temperature of 900 deg.C and in the mixed gas of nitrogen and argon in order to reduce the damage of the substrate 2 caused by the implantation. Since the concentration of interstitial nitrogen in the FZ substrate 2 becomes equivalent to the solubility of nitrogen approximately by said treatment, it has no adverse effect on a crystal. The occurrence of faults, such as slippage due to heat treatment, which is peculiar to the FZ substrate 2, is held down by the above-described treatment, and further an epitaxial layer 1 is made to grow so as to form a semiconductor element. This method eliminates the imperfection of the element caused by the occurrence of faults due to the deposition of oxygen, and enables the omission of such an I.G. process as required when a CZ substrate is used, as well as the reduction of processes.

Filed: 1985-04-02
Abstract: PURPOSE:To apply phase matching of clock signals by deciding a change position in which the adjacent storage contents differ mutually in the order corresponding to the order of a delay signal of plural latch circuits. CONSTITUTION:Suppose that an inverter train is longer so that a delay time larger than the period of a clock input signal C1 inputted to an inverter 11 exists, the waveform having a period of the clock C1 is formed.
