Title: Liquid fuel combustion device
Inventor: KAWASAKI YOSHITAKA
IPC: F23D3/14
Filed: 1978-03-20
Abstract: PURPOSE: To promote the premixing of fuel with air and improve the combustion performance, by proportionately changing the volumetric increase of a mixing chamber and air fed through air holes.  
     CONSTITUTION: Fuel vapor rising from a carbureting chamber 3 is mixed with air from air holes 3a on the first stage and the mixture rises up to the level of air holes  4a on the second stage. As the total opening area Σ a2 of the second-stage air holes  4a is equal to the increase in cross sectional area of mixing chamber Δ A 2  =  A 2  -A 1 , sufficient air is supplied to fill the reduction in pressure, thus the inner  pressure in the mixing chamber 4 on the first and second stages are equalized and  the mixture in the mixing chamber 4 is equalized by introducing the premixed gas  without interfering its rising. The fuel and air is mixed with each other to the n-th  stage which can provide complete combustion in a combustion chamber 5 positioned downstream of the mixture, without an quick increase in sooth and CO.

Title: Method of printing
Inventor: ISHII ATSUSHI
IPC: B41M5/26
Filed: 1979-03-22
Abstract: PURPOSE: To enable minute and sharp printing with low laser light energy, by making the dye layer of a printing medium from a dye combined with a magnetic metal element, projecting light or the like onto the dye layer and applying a perpendicular magnetic field thereto.  
     CONSTITUTION: A dye layer of a lake-type dye or the like combined with a magnetic metal element is coated on a soft transparent base plate of resin or the like, thereby manufacturing a printing medium 9. Laser light is iarradiated upon the moving printing medium 9 from a laser light generator 1 through a light modulator 3, lenses 2, 4 and a mirror 6. Printing paper is brought into contact with the opposite side of the medium 9 by a roller 11 and fed synchronously with the medium. A permanent magnet 14 is provided in the roller 11 so that a magnetic field is applied perpendicularly to the medium 9 in a laser light irradiation zone as shown by an arrow B. This results in attracting the magnetic material onto the printing paper 10.  
     EFFECT: The spot diameter of the laser light is reduced. The velocity of printing can be heightened.

Title: Refrigerating plant
Inventor: TAKIZAWA TAKASHI
IPC: F25B5/02
Filed: 1988-02-15
Abstract: PURPOSE:To enable a precise temperature control to be performed in response to a variation of an indoor temperature by a method wherein in case that a suction pressure of a compressor is less than a predetermined pressure, a solenoid valve for an auxiliary flow passage is opened to cause the coolant to be flowed into main refrigerant passage and an auxiliary passage. CONSTITUTION:When an indoor temperature is decreased and a degree of opening of a flow rate control valve 14 is gradually decreased, a suction pressure of a compressor 2 is decreased. As the suction pressure is less than a predetermined pressure P1, a low pressure switch 19 is closed and a solenoid valve 16 is opened. Due to this face, the refrigerant passed through a condenser 4 is divided into a main refrigerant passage A and an auxiliary passage B. An auxiliary evaporator 18 is heated by the condenser 4 and its evaporation temperature is higher than an evaporation temperature of the evaporator 4. A flow rate of refrigerant to an accumulator 8 is increased and the suction pressure of the compressor 2 is gradually increased. In turn, an amount of refrigerant flowing to the main coolant passage A is decreased and a degree of reduction of indoor temperature is reduced. When the suction pressure is gradually increased and is more than a specified pressure P2, a low pressure switch 19 is opened and the solenoid valve 16 is closed, resulting in that the refrigerant operation only with the main refrigerant passage A is operated after its changing-over operation.

Then, after the Si substrate 201 is worked to a prescribed depth by reactive ion etching based on the resist pattern, the unnecessary resist 203 is removed and the substrate 201 is cleaned. Successively, a copper film 202 is formed by the sputtering method and the recessed sections of the pattern are filled up collectively through heat treatment. Finally, a desired mask pattern 202 is formed by removing the excessive copper left in flat sections by polishing and cleaning the substrate 201.
