Title: Secondary air controlling apparatus
Inventor: OONO HIROMI
IPC: F01N3/22
Filed: 1978-05-26
Abstract: PURPOSE: To prevent sharp increase of secondary air in the transition from deceleration operation to idling operation by arranging a pressure transmission delaying means in the sir opening hole of a secondary air controlling apparatus.  
     CONSTITUTION: When an engine operates except in idling operation, a three-way valve 18 intercepts an air opening hole 19, and communicates to a negative pressure passage 17, so the intake negative pressure in the intake passage 2 on the downstream side of a throttle valve 3 is introduced into the negative pressure chamber 15 of a control valve 13 equipped with a diaphragm 14, and a relief valve 10 opens and closes a relief valve 9 according to the increase or decrease of the intake negative pressure, and the relief amount and the secondary air amount are controlled. When operation shifts from deceleration operation to idling operation, an idle detecting apparatus 20 generates signals, and the three-way valve 18 allows a negative pressure chamber 15 to communicate to the air opening hole 19. Accordingly, by means of a pressure transmission delaying means 21 (orifice) arranged in the air opening hole 19, negative pressure decreases gradually, and the relief hole 9 is closed gradually.

Title: A/d converter in pulse width modulation system of feedback type
Inventor: FUJITA TAKAO
IPC: H03M1/50
Filed: 1984-03-30
Abstract: PURPOSE:To obtain a high-precision and a high-speed A/D converter in the pulse width modulation system of feedback type by providing the second integrator which integrates a reference voltage -kE during a period DELTAt from inversion of the output of a comparator to ''0'' to closing of a counter and integrates back a reference voltage E having the opposite polarity thereafter. CONSTITUTION:The reference voltage -kE is integrated for the period DELTAt by the second integrator 12. Next, a switch SW2 is connected to the earth side, and a switch SW3 is connected to the side of a reference voltage source 11, and a reference voltage E is integrated back. In the output of the integrator 12, a ratio of reference voltages E and kE is 1:k. Consequently, the time spent in back integrating of the reference voltage E is k-number of times as long as that spent in integrating of the reference voltage -kE. When the output of the integrator 12 goes under zero, a comparator 13 detects this time t4 to send a stop signal to a counter 9 and stops the counting operation of this counter. The period from the start of back integrating of the reference voltage E in the integrator 12 to the time, when the output of the integrator 12 goes under zero, is kDELTAt, and a value proportional to the time width DELTAt is obtained.

Title: Production of hyperfine particle
Inventor: YATSUI KIYOSHI
IPC: B22F9/14
Filed: 1997-03-18
Abstract: PROBLEM TO BE SOLVED: To improve the heating efficiency and to obtain hyperfine particles with high purity at a high producing rate by instantaneously flowing a large current through a metallic member with a fine-wired shape small in a crosssectional area, heating the metallic member, melting and vaporizing the metallic member to form into a plasma state and thereafter executing cooling and solidifying. SOLUTION: A large current composed of a pulse current or the like is instantaneously made to flow through a fine wire of metal small in a cross-sectional area and is heated. By this heating, the metallic fine wire is melted and vaporized to form into a plasma state. The metallic member in a plasma state is expanded and diffused in a gas and is rapidly cooled. At this time, by cooling it in a uniform way spatially, many solid particles are solidified to grow in the gas. Next, when cooling is executed to a certain temp. or below, the growth of the solid particles stops, and the particle size thereof is regulated to final one. This particle size can be controlled by gas pressure. Successively, the formed solid particles are recovered to obtain hyperfine particles. Since the metallic member has a fine-wired shape, the metallic member can swiftly be vaporized.
