Abstract: PURPOSE:To always enable stable operation control by providing both a first spring for opening a fuel injection nozzle at a first low fuel pressure, and a second spring for opening the fuel injection nozzle at a second high fuel pressure, so that two-stage valve opening pressures can be obtained. CONSTITUTION:When a solenoid valve (not shown) is operated by the signal from a control unit to close the connecting passage between a main fuel passage 35 and a releasing passage 26 (not shown), the fuel pressure in an injection fuel passage 15 becomes a high pressure to reach a first prescribed fuel pressure P1, and when the upward force applied to the end of a needle valve 24 becomes greater than a set load of a first spring 50, the needle valve 24 is lifted so as to be apart from a valve seat 23, and fuel in a high pressure is injected through a nozzle 22. When the fuel pressure is further increased to reach a second prescribed fuel pressure P2, the upward force applied to the end of the needle valve 24 becomes greater than the aggregate load of the first spring 50 and a second spring 53, and the needle valve 24 is further lifted while compressing both the springs, and a large amount of fuel injection can be carried out.

Title: Production of soda ash for glass raw material
Inventor: ABE TAKASHI
IPC: C03C1/02
Filed: 1996-11-12
Abstract: PROBLEM TO BE SOLVED: To inexpensively produce soda ash for a glass raw material in an easier process by crushing trona ore and calcining under a specific condition. SOLUTION: Trona ore is crushed and calcined in an atmosphere containing oxygen at 500-800 deg.C for >=5min. Preferably, the trona ore is crushed to <=5mm granular diameter. The crushed trona ore may be subjected to deferrization treatment before or after the calcination, as necessary. Then, the treated trona ore is calcined in an oxygen atmosphere such as an air, preferably in a fluidized state for 5-30min. Although the resultant soda ash contains more impurities SiO2 , CaO, MgO, Al2 O3 , K2 O and Fe2 O3 than usual highly purified product, practical trouble is not generated because any organic material is eliminated by oxidation and the impurities are usable as glass raw materials.

Abstract: PURPOSE:To perform measurement readily and accurately, by obtaining a calibration curve, which shows relationship between the concentration of H2O2 water and an amount of sugar in Brix degree (Bri X %) in a light refractive type Brix scale beforehand, and measuring the H2O2 water, whose concentration is unknown, with the Brix scale. CONSTITUTION:A light refractive type Brix scale converts the refractive index of a sample solution into a Brix degree based on a specified expression of relation between the refractive index inherent to individual material and the Brix degree and displays the result. The displayed Beix degree indicates weight/weight percent of the aqueous solution of cane sugar. Meanwhile, there is a proportional relationship of y=0.44x+0.3 between the concentration (%) of H2O2 water (y) and the Brix degree (x) at a solution temperature of 20 deg.C. Therefore, the refractive index of the H2O2 water is displayed with the Brix degree on the Brix scale. The concentration of the H2O2 water can be obtained based on said Brix degree. For the concentration of the solution at temperature other than 20 deg.C, the Brix degree, which is displayed on the Brix scale, is converted into the Brix degree at 20 deg.C. Thereafter, the concentration of the H2O2 water is obtained.
