Title: Suction device for internal-combustion engine
Inventor: YOKOYAMA JUNICHI
IPC: F02B31/02
Filed: 1984-10-02
Abstract: PURPOSE:To build up a swirl as well as to improve combustibility, by letting a suction stream variable valve operate in time of low engine speed besides in time of high load, in case of an engine which installs the suction stream variable valve in suction port and forms a strong swirl in time of low load. CONSTITUTION:At a converging part at the upstream of a suction port of an engine having two suction valves 4 and 5, there is provided with a suction stream variable valve 10 installing a notch 14 to make suction air flow into the side of a port 6A in time of valve closing. In time of low load, a switch SW36A is off and a switch SW36B is on, while both solenoid valves 22A and 22B comes to be positioned as illustrated, therefore both diaphragm chambers 17A and 17B receive the atmosphere from air holes 29 and 29, and a rod 18 is pressed down by a spring 19, closing the valve 10. When the switch SW36 is turned on at high engine load and the switch SW36B is turned off at low engine speed, the chamber 17B is atmospheric pressure and the chamber 17A is negative pressure so that the rod 18 slightly goes up, and the suction stream variable valve 10 is slightly closed more than at valve full-open it time of high load and high speed, thus a swirl is strengthened.

IPC: G03G15/08
Filed: 1982-11-29
Abstract: PURPOSE:To eliminate the influence of variation in external environment such as temperature and humidity and to perform stable toner density control by providing plural magnetic circuits having gap parts, and comparing output signals of two magnetic circuits with each other and detecting toner density. CONSTITUTION:When the oscillation output of an oscillator 18 is applied to primary coils L1a and L1b, output signals corresponding to the coupling degrees of their magnetic circuits are induced at secondary oils L2a and L2b; when the toner density in a developer is within a specific value range, outputs of both secondary coils are out of phase with each other and their difference output is 0. When the coloring toner in the developer decreases in amount and its toner density decreases, the apparent magnetic permeability of the developer increases to generate some difference in coupling degree between both transformers, generating a differential output. This differential output is detected by a phase detector 19, whose output signals is compared by a potential comparator 20 with a reference voltage corresponding to reset toner density, so that toner is supplemented on the basis of the comparison output.
