Patent JP-S63247515-A (JP)
Title: Gas burner
Inventor: SHINOZAKI KENICHI
IPC: F23D14/74
Filed: 1987-04-02
Abstract: PURPOSE:To obtain a large calorific value, increase a turn-down ratio and reduce the noise of combustion, by a method wherein a combustion surface-forming wall body, on which the outlet port of secondary air feeding passage and flame keeping air ports, is extended upwardly from the end of one side of a flame port ejecting the mixture gas upwardly. CONSTITUTION:Mixture gas, ejected out of flame ports 5, is burnt to form flames on the flame ports 5 and high-temperature gas, including unburnt gas, rises along wall bodies 3, 4 while secondary air for combustion is diffused from discharging ports 14 into the high-temperature gas to mix the air and burn the unburnt gas in the high- temperature gas whereby flames F are formed in a condition that they are adhered to the combustion surfaces 3a, 4a of the wall bodies 3, 4. The flames are formed only on the lower parts of the wall bodies 3, 4 upon low input and the upper end of the flames F rises in accordance with the increase of an input while the flames F are formed to the vicinity of the upper part of the wall bodies upon high input. Flame keeping-air holes 11, communicating with the secondary air supplying passages, are formed on the wall bodies 3, 4 near the flame ports 5 between the fuel ejecting ports 14 whereby the lift of the flames is prevented by the combustion effected by air from the flame keeping air holes 11 even when the amount of ejected mixture gas is reduced.

Title: Measuring method for intensity of illumination of minute area using image sensor
Inventor: TOGASHI MITSUO
IPC: H04N1/04
Filed: 1985-04-18
Abstract: PURPOSE:To calculate the intensity of illumination of a part of minute area by calculating conversion factor of output of an image sensor having an element of minute area and intensity of illumination beforehand, and calculating the intensity of illumination of a part to measured by the output of the image sensor. CONSTITUTION:The distance (l) from a light source 1 is set to make light incident on an illuminometer 2 and an image sensor 3 equal. The measured value of the illuminometer and the output of the image sensor are compared and the conversion factor is determined. By multiplying the output of the image sensor 3 by the conversion factor, the intensity of illumination can be calculated directly. The output voltage is obtained proportionate to exposure amount by photoelectric conversion characteristic of the image sensor 3, and the exposure amount is expressed by the product of intensity of illumination and time of accumulation. Accordingly, by changing the intensity of illumination on the image sensor by adjusting the time of accumulation, the same output value can be obtained. Thus, the value of intensity of illumination can be measured widely by using the same image sensor.

Title: Waterproof camera case for underwater photographing
Inventor: FUJITA MASAMI
IPC: G03B17/08
Filed: 1993-04-09
Abstract: PURPOSE:To prevent water from entering by providing a valve releasing inside air by lifting a movable cover covering a hole when air pressure on the inside is high and covering the hole with the movable cover by water pressure underwater. CONSTITUTION:An angular hole 17 where a valve presser VS is pressing the thin rubber-plate valve V is provided on an upper transparent case 1. The valve V is placed on the vent hole 16 so as to cover the hole 16 provided on the case 1. When the temperature of a waterproof camera case rises and the inside air is heated and expanded because it is placed in a burning sun, the heated and expanded air is passed through the hole 16 and the valve V is lifted. Then, it escapes outside through the valve pressing hole VSH of the presser VS. Therefore, since the air pressure on the inside of the waterproof camera case does not rise, the case 1 or a lower cover are not swollen. Besides, even when the waterproof camera case is soaked in seawater, the seawater does not enter the inside of the waterproof camera case because the hole 16 is not opened by the water pressure by the valve V.
