Title: Light excitation surface treating device
Inventor: SATO YASUHISA
IPC: H01L21/304
Filed: 1989-12-01
Abstract: PURPOSE:To obtain a high-clean surface at the time of formation of a semiconductor device by a method wherein introducing gas is decomposed by a light excitation by the irradiation of ultraviolet light to generate radicals and the surface of a substrate is treated with the radicals. CONSTITUTION:A substrate 1 set in a treating chamber 3 consisting of a quartz material or the like is heated by infrared lamps 5. The surface of this substrate 1 is treated with the radicals of longlived chlorine atoms to be generated by decomposing chlorine gas, which is introduced in the chamber 3 from a gas introducing part 7, by a light excitation at a radical generating part 2 by the irradiation of ultraviolet light through an ultraviolet lamp 4 and an ultraviolet wavelength selecting mirror 9.

Title: Distance measuring instrument
Inventor: ISOGAWA SHUICHI
IPC: G01S7/481
Filed: 1993-11-22
Abstract: PURPOSE:To enable a self-diagnosing device to diagnose even very small abnormality of an optical system so as to improve the accuracy of the self-diagnosing function of the device by providing a polarizing plate which transmits scattered light caused by the surface abnormality of a protective glass plate and intercepts reflected light. CONSTITUTION:When a distance measuring instrument is set to a self-diagnosing mode, a light emitting element 8 is turned on and a protective glass plate 6 is irradiated with light. When a foreign matter adheres to the glass plate 6, part of the light is scattered and becomes scattered light. Another part of the light is reflected by the surface of the glass plate 6 and becomes reflected light. Since the element 8 is positioned against the glass plate 6 so that the light from the element 8 can be made incident to the glass plate 6 at the Brewster angle, the reflected light from the surface of the glass plate 6 are linearly polarized. Therefore, the reflected light is intercepted by a polarizing plate 10 and is not made to incident to a light receiving element 9. Since the polarized direction of the scattered light is variable, on the other hand, part of the scattered light is transmitted through the plate 10 and made incident to the element 9. A self-diagnosing device diagnoses the presence/absence of abnormality from the received quantity of light of the element 9 and an alarm device 12 issues an alarm when it is diagnosed that abnormality exists.

Filed: 1988-12-14
Abstract: PURPOSE: To eliminate a precipitation with a stable water solution by additionally incorporating a polyamine in a wood preservative containing a zinc compound and an aliphatic carboxylic acid as main bodies and no copper compound. CONSTITUTION: A water soluble wood preservative is constituted by incorporating a zinc compound, an aliphatic carboxylic acid and a polyamine as main bodies. The advantageous polyamine includes, for example, an aliphatic polyamine, alkyleneamine having 3 to 9 carbon atoms and 2 to 4 nitrogen atoms and the like. The zinc compound may be soluble or insoluble in water such as, for example, metal zinc, zinc oxide, zinc sulfate, zinc hydroxide. The carboxylic acid includes, for example, 5-20C carboxylic acid such as, for example, a hexanoic acid, heptanoic acid and the like. These acids are bonded to zinc to form a water insoluble salt. This salt is dissolved in an alkali medium by a complex salt forming action of the amine.  The salt formation is improved by adding a complex salt forming carboxylic acid such as, for example, a nitrile triacetic acid to 3-6C hydroxycarboxylic acid, lactic acid, tartaric acid or citric acid.

Filed: 1990-11-21
Abstract: PURPOSE:To access to a most priority address line when the same address is input to different address lines, and to simultaneously write a plurality of data by adding a simple logic by providing a priority order at input address lines. CONSTITUTION:A priority processor 600 inputs word selection lines WS10 - WS1n, WS20 - WS2n from address decoders 110, 120, preferentially processes the address of an address bus 101, and sends word lines W10 - W1n, W20 - 2n to a memory cell array 300. When a word selection line WS1i is selected, the SW2i is invalidated, and when the same address is input, only a word line W1i to the bus 101 is validated. A coincidence detector 700 generates a positive polarity coincidence signal 701 when the addresses of the buses 101, 102 are equal, generates a negative polarity coincidence signal when both the addresses are difference, and transfers an access or not the same address to a data output unit 500. When the configuration is provided in a multi-port memory, a plurality can be simultaneously written without overhead.

Title: Method and apparatus for data acquisition
Inventor: YAGI NORIAKI
IPC: G01D1/12
Filed: 1995-12-04
Abstract: PROBLEM TO BE SOLVED: To record necessary and sufficient information by a method wherein a signal is sampled at a reproducible cycle and a maximum peak value and/or a minimum peak value within a cycle are held at every cycle which is longer than the reproducible cycle so as to be recorded at every hold cycle. SOLUTION: A flaw detection signal about a steel plate P by an ultrasonic flaw detection apparatus 1 is input to an A/D conversion part 3 via an LPF 2. The conversion part 3 comprises an input part with a total of eight channels composed of, e.g., four channels for a flaw signal, of one channel for a wall thickness signal and of three channels for an event signal, and every channel performs a sampling operation at a frequency of, e.g. 1kHz. A signal processing part 4 decides a processing method for every channel. For example, a flaw signal with a maximum peak value is held with reference to a sampling signal, that with a threshold value or higher is set at -5%, and that with the threshold value or lower is set at 0% with reference to a minimum peak value.  Consequently, the flaw signal is recorded at every millisecond, and the flaw signal at the threshold value or lower is not recorded. Therefore, the amount of recorded data can be reduced largely. In this manner, the operability of a retrieval operation and an analytical operation can be enhanced largely.
