Inventor: HEMANSA KUMAA BUIKURAMASHINGU
IPC: G02B21/00
Filed: 1990-04-20
Abstract: PURPOSE: To eliminate the need of an aperture in a near-filed optical microscope by using a very small metallic or dielectric chip which is about the size of an atom and applying dither motion to the chip and a sample. CONSTITUTION: The small chip 14 about the size of the atom is disposed just near the surface of a sample 20. The dither motion is applied to the chip 14 in a direction 22 nearly vertical to the surface of the sample at 1st frequency, and simultaneously the dither motion is applied to the sample 20 in a direction 24 nearly parallel with the surface of the sample at 2nd frequency. The amplitude of the dither motion is selected to match desired measured resolution, and light energy is radiated to the top of the chip 14 so as to detect scattered light from the chip 14 and the surface 20 at difference frequency. Thus, the image of the surface of the sample is obtained with the resolution of sub wavelength without using the aperture.

Title: Combustion appliance
Inventor: TOMINAGA NAOTO
IPC: F23N5/24
Filed: 1996-03-29
Abstract: PROBLEM TO BE SOLVED: To provide a combustion device capable of properly deciding the deterioration of ventilation thereof and precisely deciding the life thereof. SOLUTION: A test reference fan electric power, a target air quantity with ventilation deteriorated which corresponds to the electric power and relational data are stored in a reference data storing part 28. The target air quantity whose temperature is corrected by a target air quantity correcting part 34 is regarded as a true target air quantity. With the lapse of a prescribed time after the combustion of a device stops, a combustion fan is rotated so that the quantity of air supplied to a burner from the combustion fan 5 reaches the true target air quantity.  When the detected value of consumed power of the combustion fan 5 at this time deviates from the toletance of the consumed power given to the test reference fan electric power, a comparing and deciding part 41 decides this state as a ventilation deterioration progressing state and outputs a ventilation deterioration progressing signal. The ventilation deteriorating state of the device can be recognized and decided based on the output of the ventilation deterioration progressing signal.

Title: Operation of fuel cell
Inventor: KUWABARA TAKESHI
IPC: H01M8/04
Filed: 1983-06-09
Abstract: PURPOSE:To maintain high cell performance for a long time by separately adding steam to oxidizing gas and fuel gas, and controlling the adding amount in accordance with operating condition and load current of a fuel cell. CONSTITUTION:A pair of porous electrodes of an anode 2 and a cathode 3 are arranged with electrolyte 1 of phosphoric acid interposed. Fuel gas such as hydrogen is supplied to the back of the anode 2 and oxidizing gas such as oxygen to the back of the cathode. Electric energy generated by electrochemical reaction is taken out from the electrodes 2 and 3. In accordance with load current of fuel cell, the amount of steam adding to the oxidizing gas is controlled to the amount of 1-10 times of equilibrium steam partial pressure of the electrolyte 1. The amount of steam adding to the fuel gas is controlled to the amount of two times or more of equilibrium steam partial pressure of the electrolyte 1 and to the amount equal to or less than total steam partial pressure on the oxidizing gas side which is calculated on the assumption that water generated by reaction corresponding to load current is transferred to the oxidizing gas side. Thereby, the volume of phosphoric acid in the electrolyte 1 is kept constant and phosphoric concentration in the fuel cell is uniformed.

IPC: F23D11/10
Filed: 1989-04-24
Abstract: PURPOSE:To prevent local overheating of a burner head and peripheral parts and suppressing lifting combustion and provide an excellent and uniform state of combustion by making the total sum area of flame openings that are above the center line of the burner head smaller than the total sum area of flame openings that are below the center line. CONSTITUTION:Since a burner head 12 is covered and tightly sealed by a burner lid 14, a mixture gas is jetted out of main flame holes 15 and small auxiliary flame holes 16 provided in the circumferential wall of the burner head 12 in order to form flames. Since the auxiliary flame holes 16 are provided only on the lower side of the center line of the burner head 12, the mixture gas that flows into the burner head 12 exits by its own weight more in the lower section and less in the upper section of the burner head, but by the existence of the auxiliary burner holes 16 the main flame holes 15 keep a proper flame hole load, and the local overheating of the burner head 12 and peripheral parts is prevented and, furthermore, the lifting combustion is suppressed and an excellent and uniform state of combustion is provided.

Title: Method for measuring semiconductor device
Inventor: HAYASHI HIROSHI
IPC: H01L21/66
Filed: 1988-04-27
Abstract: PURPOSE:To make it possible to correct and control the position of a chip based on a signal that is outputted at every test, by reading the coordinates for every chip, and controlling the operation of an advancing probe based on the relative positional relation of each chip. CONSTITUTION:When the measurement of a semiconductor chip 5 of a wafer 1 is finished, a probe that is in contact with the wafer is stopped. When its position agrees with the X coordinate of a semiconductor ship of a wafer 2 to which a probe is in contact, the probe in contact with the wafer 1 is started. Since the probes in contact with the semiconductor chips advance at the same time, the X coordinate of the semiconductor chip is increased at the periphery of the wafer 1 at first. At this time, the probe on the wafer 1 is stopped again, and the agreement for the coordinate in the direction X is obtained. When the coordinate of the wafer 1 in the direction X agrees with the coordinate of the wafer 2 in the direction X, the relative coordinates of the semiconductor chips of the wafers 1 and 2 in contact with the probes agree completely. Thereafter, deviation occurs only at the peripheral part of the wafer. Therefore, the deviation is corrected at every time.
