Title: Contactless relay
Inventor: IITAKA YUKIO
IPC: H03K17/73
Filed: 1979-12-30
Abstract: PURPOSE:To secure a step property for the response property and thus to obtain a response property similar to a contact relay, by triggering the SCR when the constant-on transistor is turned on and while the receiving semiconductor switching element is turned off. CONSTITUTION:The receiving semiconductor switching element 9 is off in case no input signal is in the element 9, and the current flows in a route of the power source 4-the base of the transistor 7-the power source 4. Thus the transistor 4 is turned on, and the SCR is not turned on. Accordingly the load 5 has no operation. The element 9 is turned on with the transmission given by the receiving semiconductor switching element 3 to flow the current. Thus the base current of the transistor 7 is reduced to turn off the transistor 7. As a result, the current passed through the resistance 6 flows also to the gate of the SCR, and the SCR is turned on with increment of the current at the gate. Thus the load 5 has an operation.

Title: Low nox type high combustion chamber load burner
Inventor: OGASAWARA HIDEYUKI
IPC: F23C99/00
Filed: 1984-08-15
Abstract: PURPOSE:To enable high combustion chamber load combustion to be consistent with the low NOx, by a method wherein 2 auxiliary combustion chambers are formed, gas under combustion reaction is recirculated between a 1-stage auxiliary combustion chamber and and a 2-stage auxiliary combustion chamber, and 2-stage combustion of the air is added between the 1-stage and 2-stage auxiliary combustion chambers. CONSTITUTION:A 1-stage air, being less than a theroretical air amount, is injected in a 1-stage auxiliary combustion chamber 4 through a gap between a swirler 1 and an inner cone 2 as the air is swirled. Gas under combustion reaction, flowing after mixed in a 2-stage auxiliary combustion chamber 5, is contracted by a first contraction part 7 to forcibly progress mixing with the air. A part thereof is inverted and is caused to reversely flow to the rear surface of the 2- stage auxiliary chamber, and is recirculated to the 1-stage auxiliary combustion chamber to assist reduction combustion. Other gas under combustion collides and is mixed with a 2-stage air 9 injected through the side of the 2-stage auxiliary combustion chamber, and with this, mixing with the 2-stage air is forcibly progressed in a second contraction part 8, and the mixture is exhausted in a main combustion chamber as it is completely burnt. This prevents increasing of a flame temperature without slackening combustion, causes rapid progress of reduction combustion under a lean oxygen state, and enables promotion of combustion reaction and rapid combustion of low NOx.

Title: Fuel cell differential pressure control device
Inventor: YAMAGUCHI MASANORI
IPC: H01M8/04
Filed: 1985-08-05
Abstract: PURPOSE:To follow quick load change without use of a water-seal container by forming two spaces by partitioning a container with a flexible film, and connecting one space to an anode side and other space to a cathode side. CONSTITUTION:A cell container 1' is partitioned into two spaces 1'-1 and 1'-2 with a partition 14 and a thin film 15. The space 1'-1 is connected with a cathode outlet pipeline and the space 1'-2 is connected with an anode outlet pipeline. Thereby, the equivalent volume of the anode and cathode is increased, the time constant in pressure change is made larger, and differential pressure control is facilitated with a differential pressure control valve. In addition, when the pressure quickly varies, generation of differential pressure is retarded by displacement of the flexible film. Therefore, the system can follow quick load change without use of a water-seal container.

IPC: H02M3/155
Filed: 1986-07-21
Abstract: PURPOSE:To get up high switching speed and improve efficiency, by giving forward bias and reverse bias in turning ON and OFF a switching transistor respectively. CONSTITUTION:When a transistor 2 is forward-biased by the current flowing to a resistance 7 and begins to be biased OFF, the base current flows to the transistor 2 by the voltage induced by a coil 3 and positive feedback action is brought about and the transistor 2 rapidly turns OFF. When the current flowing to the coil 3 gets to more than the designated value, flyback action is brought about to the coil 3, to which negative voltage is induced. Thus, the transistor 2 is reverse-biased and rapidly biased OFF.
