Abstract: PURPOSE:To obtain the two photon absorption type optical fiber laser amplifier which is less degraded in amplification efficiency and can realize the practicable optical fiber laser amplifier by using pumping light of a prescribed wavelength band and pumping the optical fiber by two photon absorption. CONSTITUTION:The optical fiber laser amplifier which amplifies signal light by exciting a rare earth element doped optical fiber 1 formed by doping the rare earth element to the optical fiber by the pumping light from a pumping light source 100 is constituted to pump the optical fiber by the two photon absorptions using the pumping light of 1.0 to 1.6mum band outputted from the pumping light source 100.

Title: Automatic fire extinguishing device for kerosene combustion device
Inventor: NIWA OSAMU
IPC: F23N5/20
Filed: 1999-08-31
Abstract: PROBLEM TO BE SOLVED: To restrain the generation of incomplete combustion gas and prevent the diffusion of the same into a room upon the fire extinguishing operation of a kerosene combustion device. SOLUTION: A pot 3, whose side wall is provided with air ports 3a, is arranged in the supplying duct 2 of combustion air, a red-heat type heater 6 is attached to the pot and air as well as fuel are supplied by a combustion fan 1 and a fuel supplying means 4 to effect igniting combustion. An air sending passage 9, connected to a front surface outlet port 15, is provided in the frame body 7 of a combustion device and combustion gas, discharged from the pot into the air sending passage 9, is sent out of an air outlet port by an indoor ventilating fan 8.  When fire extinguishing means 10 is operated, the energizing of the heater 6 is started and the operation of the fuel supplying means is stopped, then, the control means of the indoor ventilating fan maintains a high-speed rotation until the counting of a first timer is finished and, thereafter, switches the rotation into a low-speed rotation and returns the indoor ventilating fan into the high-speed rotation after combustion flame becomes small or fire is extinguished. While a large amount of incomplete combustion gas is discharged from the pot 3 on the way of fire extinguishing, the indoor ventilating fan maintains low-speed rotation and combustion gas, discharged to the outside of the frame body, ascends to the ceiling of the room by natural convection whereby the diffusion of the incomplete combustion gas is prevented.

IPC: G01T1/29
Filed: 1983-12-26
Abstract: PURPOSE:To make it possible to accurately measure the diameter of ion beam condensed in a sub-micron order, by measuring the diameter of ion beam by utilizing a boundary present on the surface of a flat semiconductor crystal. CONSTITUTION:When ion beam is allowed to vertically irradiate the surface of a semiconductor 1, secondary electrons 4 are emitted from the semiconductor 1 and the intensity of the electrons 4 is measured by a secondary electron intensity measuring apparatus 5. When ion beam 3 is scanned in this state and irradiated so as to traverse the boundary of two regions 1a, 1b, the intensities of emitted secondary electrons are changed in the regions 1a, 1b. Therefore, the diameter of the ion beam is calculated by the product of a time required in changing the intensity of secondary electrons from etaa to etab and the scanning speed of the ion beam.

Title: Abnormal shadow detector
Inventor: SHIMURA KAZUO
IPC: G06T1/00
Filed: 1990-09-14
Abstract: PURPOSE:To enable highly accurate detection by judging a candidate based on an area and a maximum width of a linear pattern within an expansion candidate area in an area from which the candidate and the linear pattern are both extracted on a radiation image. CONSTITUTION:An expansion candidate area 4 is presumed to contain an area from which a tumor shadow candidate 7 and a blood vessel shadow 1 are both extracted and an area of the blood vessel shadow 1 within the area is represented by S. A size of the blood vessel shadow 1 is determined according to an algorithm to determine the size of the blood vessel shadow at pixel positions moving a specified pixel P0 in the expansion candidate area 4 and within the blood vessel shadow 1 extracted and a maximum width (d) thereof is obtained. A diameter of a tumor shadow is determined as size of the blood vessel shadow. When the area S and the maximum width (d) of the blood vessel shadow 1 are determined in the expansion candidate area 4, it is judged whether the tumor shadow extracted in a computer system is true or not based on the area S and the maximum width (d). As a result, even when an extraction filter is not complete, an abnormal shadow can be discriminated from a linear pattern thereby enabling highly accurate detection of the abnormal shadow.

Title: Measuring instrument with time correction function
Inventor: OGINO KENJI
IPC: G04G5/00
Filed: 1999-08-31
Abstract: PROBLEM TO BE SOLVED: To simplify a time correction operation by setting a time part that is equal to or less than a specific time unit to a specific value when the time of a real-time clock is within a pre-specified correction error range. SOLUTION: A memory 31 of a time correction control means 30 stores a specific value within a correction error range in advance. A judgment means 32 of the time correction control means 30 is started by a time correction start command, thus reaching the current value of a real-time clock 20. When 'minute' (the same applies to minute, 'hour', and 'second') of the read current time is less than 30 minutes and within a correction error range, the minute and second are set to zero. When the 'minute' is equal to or more than 30 minutes and 59 minutes minus (current value) is within the correction error range, the minute and second are set to zero. Also, when current time is not 23 hours, time is advanced by one hour.  When the current time is 23 hours and date is the end of a month excluding the last of the year, the month is advanced by one and the date is set to the first one, the year is advanced by one at the last of the year as the New Year, and the date is advanced by one except the end of a month. In either case, the real-time clock 20 is updated by a time correction means 33 based on the change.

Abstract: PROBLEM TO BE SOLVED: To provide an inexpensive and miniaturized liquid mixing apparatus simple in structure by providing electromagnetic opening and closing valves on the upstream side of first and second flow rate measuring pipelines and providing a control device controlling a timer so as to open the respective electromagnetic opening and closing valves for a predetermined time. SOLUTION: For example, when a first liquid A and a second liquid B are desired to be mixed in a ratio of 1:1, if the flow rate of the first liquid A is 1l/min and the flow rate of the second liquid B is 5l/min, the flow rate ratio of both liquids A, B becomes 1:5. Therefore, the opening time of an electromagnetic opening and closing valve 23 by the timer T of a control device 26 may be set to twice the opening time of an electromagnetic opening and closing valve 22 by the timer T1 . If the setting time of the timer T1 is set to 5min and the setting time of the timer T2 is set to 10min, 5l of the first liquid A and 50l of the second liquid B are supplied after the elapse of 10min. These liquids are mixed in a mixing liquid tank 2 and a mixed liquid A+B is obtained in a mixing ratio of 1:10.
