Title: Suction device for internal-combustion engine
Inventor: INOUE TOKUTA
IPC: F02M31/135
Filed: 1984-02-06
Abstract: PURPOSE:To aim at improvements in heating efficiency instead of makig a suction heating device exert any adverse effect on charging efficiency, by installing a valve, which opens only in time of high load, in an auxiliary suction passage having an equivalent pipe length identical with that of a main suction passage as well as installing the suction heating device in the main suction passage. CONSTITUTION:An auxiliary suction passage 16, which is branched to a main suction passage 12 interconnected to an air cleaner 9 and interconnected to the main suction passage 12 via a surge tank 14 at its one end and a control valve 19 at the other end, is installed, and an equivalent pipe length between these main and auxiliary suction passages 12 and 16 is equalized in size. In time of low load, since suction air passes the main suction passage 12 alone, heating efficiency in time of starting, etc., is improved so better, while in time of high load, a solenoid suction pressure selector valve 33 is set in motion, thus the control valve 19 opens. With this constitution, owing to these main and auxiliary suction passages 12 and 16, charging efficiency is improved and, what is more, suction resistance in the suction heating device is thus negligible.

Abstract: PURPOSE:To make any drawback such as a paper jam preventable before it happens, by selecting a selector device to the side of a paper discharge tray with a controlling device when detecting a fact that copying paper is fully loaded on paper refeed cassette by a loadage detecting device. CONSTITUTION:In a conveying passage leading to a paper refeed cassette 50, there is provided with a copying paper detecting sensor Se2 whose actuator is projected onto a guide plate 70, and when it detects a tip of copying paper to be discharged out of a pair of paper discharge rollers 21 of a copying machine body part 1, it drives a counter, making it count the number of sheets of discharge paper, while it also drives rollers 71-74 and a turnover roller 76, whereby the copying paper is directly or reversedly housed in the refeed cassette 50 according to a position of a second selector claw 65. And, when the number of sheets of the copying paper counted by the counter reaches the full load, a controlling device turns a solenoid to ON, selecting a first selector claw 60 to an upper step position, and the copying paper afterward is discharged onto a paper discharge tray 45.

Filed: 1980-02-19
Abstract: PURPOSE: To make possible the continuous operation of a pressing machine and improve its productivity and safety by moving the moving table mounted with lower dies to each stop position in synchronization with the ascending and descending movements of a slide.  
     CONSTITUTION: While a work is being pressed with one lower die 12, the next work is inserted into the other lower die 11 positioned on the outer side of the frame. When the pressing with the lower die 12 ends, the male die 4 mounted to the under surface of a slide 2 ascends and when it goes higher than the top end of the product, a moving device 13 is moved by the connecting shafts 14, 15 connected to the slide 2 and a moving table 6 turns clockwise, so that the lower die 11 inserted with the next work is positioned up to the stop position opposing to a male die 4. This movement is usually accomplished during the time when the male die 4 rises to the uppermost. Hence, the male die 4 descends for the purpose of next working without stopping at the uppermost ascending point. During this time, the product is taken out from the lower die 12 having finished working and the next work is inserted therein.
