Abstract: PURPOSE:To contrive the saving of electric power and the suppression of generating and accumulating of tar, and obtain smooth combustion by a method wherein the energizing time for a heating heater is limited within only an igniting time by the heating of whole vaporizing cylinder due to the utilizing of combustion heat generated by the combustion. CONSTITUTION:A large part of a combustion gas generated in a combustion space 16 is flowed to outside from a blow-off hole 19 affected by a masking shield 21 and the like through a flowing space 20 located at the lower part of a vaporizing cylinder 1. Thereby, a bottom surface 6 of the vaporizing cylinder 1 is contacted with the combustion gas in the same manner as the side surface thereof and the large part of the combustion gas is flowed along the vicinity of the vaporlizing cylinder 1, accordingly, the feedback of the combustion heat for the vaporizing cylinder 1 is performed sufficiently. Further, the feedback is performed almost uniformly throughout the whole vaporizing cylinder 1. Therefore, the energizing of a heating heater 2 becomes unnecessarily during normal combustion and the saving of electric power can be contrived. The generation and accumulation of tar can be prevented due to the uniform heating throughout the whole vaporizing cylinder by the combustion gas.

Title: Facsimile equipment
Inventor: OKADA OSAMU
IPC: H04M11/00
Filed: 1991-03-14
Abstract: PURPOSE:To call a dial only to an appropriate opposite party. CONSTITUTION:When a telephone number is inputted from a telephone number input means J4, a telephone number collation discriminating means 6 decides whether the telephone number is registered in a telephone number registering means 5 or not. The telephone number registering means 5 registers the plural telephone numbers at every identification code of respective operators and retrieves the telephone number corresponding to the identification code only when the inputted identification code is registered. When the inputted telephone number is registered, a transmitting/receiving means 8 calls the dial to the opposite party of the telephone number. Then a communication line comes to be connected so that the transmission of original information and polling reception are executed. Thus, an erroneous call to the unrelated opposite party and private use, etc., are prevented by appropriately selecting the telephone number previously registered.

Title: Optical measuring method for solid sample and sample holder used in this method
Inventor: TERAJIMA KOICHI
IPC: G01N21/17
Filed: 1989-03-03
Abstract: PURPOSE:To accurately measure nonuniformity by irradiating a sample surface with light and measuring the intensities of the reflected light, transmitted light and emitted light thereof while oscillating the entire part of the sample at a prescribed frequency f and detecting the component of the frequency f from the signals thereof. CONSTITUTION:The sample 13 is irradiated with the white light from a light source 9 through a spectroscope 11. While the entire part of the sample 3 is moved at a specified speed in one direction by the sample holder at this time, the sample is oscillated at the specific frequency f in the same direction. The reflected light from the sample 3 is condensed by a mirror 12, is detected by a photoelectron multiplier 14 and is converted to the electric signal. This signal consists of a DC component R and the AC component DELTAR of the frequency f. Two kinds of these signals are passed through a divider 17 and DELTAR/R is recorded by a recorder 18. The plotting of the DELTAR/R in the position of the sample where the light falls can be made from the moving speed of the sample 3 by allowing the time to start moving the sample and the time to start recording with the recorder to coincide with each other. The nonuniformity of the reflectivity of the sample is thus measured.
