Filed: 1992-05-11
Abstract: PURPOSE:To manufacture a hot dip aluminum plated chromium-contg. steel sheet excellent in workability and plating adhesion. while inline annealing is executed in a Sendzimir type hot dip plating line. CONSTITUTION:A cold rolled sheet contg. 10 to 25% chromium in steel is heated to 550 to 700 deg.C in a weakly oxidizing furnace in which the air ratio of a heating burner is regulated to 0.9 to 1.5 to form an iron oxidized film on the surface of the steel sheet. After that, it is heated to >=800 deg.C as well as to the sheet temp. on the outlet side of the weakly oxidizing furnace +300 deg.C or below and is subjected to softening. Simultaneously, only the iron oxidized film is reduced, and after that, hot dip aluminum plating is applied while cooling is executed. Since the plating is executed while the inline annealing is executed, the annealing-pickling stages can be obviated, thus enhancing the merits in the viewpoints from the cost and the term of the manufacture.

Title: Output voltage correcting circuit for switching regulator
Inventor: ISHIBASHI MASAMORI
IPC: H02M3/335
Filed: 1980-08-28
Abstract: PURPOSE:To correct an output voltage without losing stability, by controlling the output voltage through a charge/discharge circuit controlling an adjusting current of an error amplifier. CONSTITUTION:When an input DC voltage Vi is higher, the on-time of a transistor (TR)Q1 is longer and an average charging voltage V1 of a capacitor C2 is smaller. On the other hand, the on-time of an output switching TRQ5 is shorter. The slope of a triangle wave applied to a base terminal P3 of a TRQ2 is expressed as dv/dt I/C and when constants are selected suitably, even if the on-time of the TRQ3 is changed, no collector current of the TRQ3 changes. Thus, an output voltage V0 becomes constant.

Abstract: PURPOSE: To always maintain gas exhausting performance of an engine in a good condition by providing same with an accelerating fuel supply system in a carburettor thereof which is operable to supplementally supply an optimum amount of fuel for an appropriate period of time in accordance with accelerating conditions of the engine so as to compensate for fuel air ratio during acceleration of the engine.  
     CONSTITUTION: If a throttle valve 7 is opened, for example, to a B position in order to accelerate an engine from its stationary state, suction negative pressure acting at a negative pressure extracting port 27 is decreased. This change of negative pressure is transmitted to chambers 22 and 23 of a negative pressure responsive valve 20 through conduits 28 and 29, respectively, whereupon negative pressure is decreased instantaneously in the chamber 23 while negative pressure is gradually decreased in the chamber 22 due to the existence of a throttle 30 so that a diaphragm 24 is moved leftwardly against the urging of a spring 26. As a result, a valve body 25 of the valve 20 is moved leftwardly to open an accelerating fuel supply passage 12. Meanwhile, negative pressure is allowed to act upon ports 14a, 14b. Accordingly, accelerating fuel is sucked into a suction bore 2 from a float chamber 4 through the passage 12 and the ports 14a, 14b while the valve body 25 is held to the position for allowing the passage 12 to be opened.

Abstract: PURPOSE:To provide a room for insulation and protection of the body of a watt-hour meter or the like at the testing or the like thereof, by operating a switch for connecting or releasing a voltage circuit and a current circuit and releasing the connection therebetween through separation or connection between an element section and a terminal section to eliminate the need for work of moving a slide piece especially for the use of a real load. CONSTITUTION:When a cover housing an element section 21 and a base housing a terminal section 12 are connected, a switch 24 is automatically closed by a magnetic force of a permanent magnet 25 to connect a voltage circuit and a current circuit of a watt-hour meter electrically, allowing the use of a real load. When the element terminal section 21 is separated from the terminal section 12, the switch 24 is automatically opened to electrically release the voltage circuit and the current circuit making ready the testing of a false load of the element section 21. Thus, since the element section 21 and the terminal section 12 are separable as cover side on one hand and base side on the other, the use of the element section 21 alone is made possible for the adjustment and the testing of measuring errors, thereby requiring no combinated use the terminal section 12.
