Title: Combustion device
Inventor: ITO MASARU
IPC: F23D11/10
Filed: 1986-03-25
Abstract: PURPOSE:To miniaturize a fan for combustion and stabilize the temperature of an evaporating tube by supplying secondary air for cooling the evaporating tube as well as for combustion by a convection fan. CONSTITUTION:When combustion is effected in a flame keeping ring 4, an evaporating tube 2 is heated. Then, a convection fan 12 is rotated to send out air into a warm-air passageway 13, mix it with combustion exhaust gas and discharge the warm-air. At the same time, air is pushed into an air chamber 53 from the secondary air intake port 50 of a combustion tube 14. A part of the air, entered into the air chamber 53, is supplied into a combustion chamber 17 through the secondary holes 51 of a secondary ring 52 while the balance of the air enters into a space 8 between the evaporating tube 2 and an evaporating tube cover 9 to cool the evaporating tube 2, thereafter, is discharged into an exhaust tube 54. According to this method, a combustion fan is not employed for supplying the cooling air of the evaporating tube and secondary air for the combustion chamber, therefore, a combustion fan may be miniaturized.

Title: Thermal recording material
Inventor: TORII HIDEYASU
IPC: B41M5/30
Filed: 1985-04-01
Abstract: PURPOSE:To obtain the title material having high flexibility and heat resistance, by a method wherein a thermal recording layer is provided on the surface of a base material sheet and a heat resistant layer is set on the other surface thereof and the heat resistant layer is made of a resin having siloxane bonds in its molecules. CONSTITUTION:A polyurethane resin or a polyurea resin having siloxane bonds in its molecules is employed for a heat resistant layer. Approximate 5-50pts.wt. of the siloxane bond are contained in 100pts.wt. of the resin. With the atomic weight of the silicon of under about 5wt% of the available resins, the heat resistant layer formed of the resins is to have insufficient heat resistance. On the other hand, with that of over 50wt% thereof, the solubility and the flexibility of the available polyurethane resin and/or polyurea resin in the organic material decreases, resulting that the resin is not suitable for forming the heat resistant layer. A thermal recording layer is formed by a method wherein a binder resin for forming the thermal recording layer is added in an organic solvent together with a dye or a pigment and the fluid dispersion thus obtained is coated on a base material and dried.

Title: Double optical path interference length measuring instrument
Inventor: OKAJI MASAHIRO
IPC: G01B11/00
Filed: 1986-03-26
Abstract: PURPOSE:To measure respective components of motion whose degree of freedom is six in the direction of the motion separately from other components by combining plural plane mirrors, etc., with an interferometer composed of two polarization beam splitters, etc., arranged in parallel. CONSTITUTION:The interferometer consists of the polarization beam splitters PBS1 and PBS2, a 1/2-wavelength plate HP put between the both, a cube corner prism CCP set at right angles to an optical path, and a 1/4-wavelength plate QP which turns a plane of polarization by 90 deg. on forward and back optical paths to a reflection mirror. Then, incident light 1 to the interferometer which is polarized linearly by 45 deg. passes through optical paths in the order of numbers 1-11, and 1-2'-10'-11 and is coupled again together. Thus, two kinds of optical paths are provided, so the measurement sensitivity of parallel traveling components in the motion direction is doubled and the CCP is also used, so even if either or both of reflection mirrors M1 and M2 slant in an optional direction, the incident light and reflected light maintain parallelism all the time and the wave front of the interference light does not slant. Thus, deviation in optical adjustment due to an optional motion component is compensated automatically.
