Title: Liquid fuel combustion device
Inventor: IMAJIMA MITSUHIRO
IPC: F23D11/40
Filed: 1978-04-20
Abstract: PURPOSE: To perform combustion with a fixed air-fuel ratio by utilizing spray principle for fuel supply, and to prevent tar generation by effective atomization of fuel.  
     CONSTITUTION: Part of air, absorbed through an air induction inlet 12', goes through a ventilating fan 4 to be sent into a high temperature mixing room 7 from an induction inlet 12 after being made high temperature air by an air heater 10. On the other hand, part of air, supplied through the air induction port 12', first goes into a ventilator 6 through a ventilating fan 3 to reach an evaporation-mixing room 7 through a contraction part 5. At this time, as the high pressure air passes the contraction part 5, fuel is sucked from a combustion nozzle 9 connected to a fixed oil level device 8, causing atomization of fuel due to the high pressure air. This atomized fuel is evaporated in the evaporation-mixing room 7 with high temperature air, goes through flame keeping plate 14, and form combustion flame 16 after being ignited by an igniter.

Title: Surge voltage absorbing circuit
Inventor: NISHIMORI ISAMU
IPC: H03K17/08
Filed: 1992-02-03
Abstract: PURPOSE:To protect a main transistor against the surge voltage for a switching circuit by providing a subtransistor between the collector and base terminals of a switching transistor to absorb the surge voltage. CONSTITUTION:A main transistor TR 1 is switched by a driving pulse to be switched on and off by e base current Ib1 and base adverse current Ib2 respectively and then turned off. Then the surge voltage is generated by the wiring inductance L when a main circuit current I is rapidly attenuated. Under such conditions, the current I obtained by adding a current I1 flowing to a diode 3 and a resistance 4 to a current I2 flowing to the TR 1 is attenuated by an extent close to the attenuation specific linear value of a subtransistor TR 2. Thus the reduction rate is reduced and therefore the energy of the surge voltage is also reduced. The current I is bypassed by the TR 2 and the reduced energy is consumed more. As a result, the surge voltage can be absorbed.

Title: Back face projection screen
Inventor: YADA YUKIO
IPC: G03B21/62
Filed: 1985-03-11
Abstract: PURPOSE:To scale down a device and to attain a uniform and bright screen by installing plural prism groups extending in an arc-like shape on the back face of the screen and forming the prescribed total reflecting surface thereon. CONSTITUTION:Plural prisms 1, which extend in an arc-like shape and are arrayed, are installed on the back face side of a back face projecting screen S, and each prism 1 has an incident surface 1B and a reflecting surface 1A. Then on the reflecting surface 1A a total reflecting surface is formed so that an incident light beam from the incident surface 1B can be total-reflected and can emit to the side of an observation surface. With this constitution, a light beam incident from backward the screen at an acute angle comes out uniformly and efficiently on the observation surface with the aid of the shape of the prism and the action of the total reflection. Accordingly the relative position of a projector becoming a light source can be located obliquely backward so as to scale down the device, and the uniform and bright screen can be obtained.

Title: Fluorescence x-ray analyzer
Inventor: NAKATANI TAKEHIKO
IPC: G01N23/223
Filed: 1989-02-27
Abstract: PURPOSE:To achieve a higher analysis at a quantitative analysis or the like by correcting counts considering the effect of higher order rays of a coexistent element. CONSTITUTION:As Cu other than P coexists in an analysis, higher order rays (4-order rays) of CuKalpha are detected with an X-ray detector 2 simultaneously together with PKalpha and an output thereof is inputted into an upper limit value selection circuit 6a and a lower limit value selection circuit 6b through an amplifier 4. Counts n2 and n1 of upper and lower limit counters 8a and 8b are transferred to a subtracter 10 and a difference n12 (=n1-n2) between counts n1 and n2 is calculated to extract a detection pulse alone based on X rays (PKalpha) of an element. An arithmetic device 12 calculates true counts n0 based on a special formula from values of counts n1 of the lower limit counter, a subtracting value n12 of the subtracter and a set dead time tau. Thus, a counting rate (CPS) is determined by dividing the counts n0 after corrected by a unit time (t) set with a timer 16.

Filed: 1995-03-08
Abstract: PURPOSE: To obtain a zoom lens capable of enhancing the degree of freedom in design without making a video camera thick or slender and making the diameter of a front lens smaller though the angle of view at a wide-angle end is wide. CONSTITUTION: This zoom lens 10 is constituted by arranging a 1st group 11 having positive refractive power, a 2nd group 12 having negative refractive power, a diaphragm 15, a 3rd group 13 having the positive refractive power, and a 4th group 14 having the positive refractive power in order from an object side. The 1st and the 2nd groups 11 and 12 constitute a variable power system. The 1st group 11 is constituted by arranging a concave lens L1, a rectangular prism P, a convex lens L2, and a bonded lens of a concave lens L3 and a convex lens L4 in order from the object side. Since the optical axis of a light beam from the object is bent at a right angle by the prism P, the length in an incident optical axis direction is drastically shortened.  By allowing the prism P to intervene, a distance between the concave lens L1 and the group of the lenses L2 to L4 becomes long and the rear side principal point of the 1st group 11 are brought near to the rear, so that the focal distance of the 1st group 11 is shortened, which is advantageous to attain the wide angle.
