Filed: 1983-07-14
Abstract: PURPOSE:To increase an output of an engine as a whole by establishing the total sum of the products of times and opening areas of a suction valve mounted to at least one cylinder, wherein the suction valve opens at high rotational speeds of the engine, at a greater value than the total sum of the products of times and opening areas of a suction valve mounted to the other cylinder. CONSTITUTION:In ports 11 and 12 of each cylinder are mounted a pair of a suction valve 13 and an exhaust valve 14 for opening and closing these ports, the number of the valves amounting to four in all. A working angle of a cam 21 actuating the suction valve 13 of a first cylinder is established so as to be wide, and the total sum of the products of times and opening areas of the suction valve 13 mounted to the first cylinder is established at a greater value than the total sum of the products of times and opening areas of the suction valve 13 mounted to a second cylinder. Accordingly, a suction amount of the first cylinder is increased to an extent nearly equal to a suction amount of the second cylinder. There is therefore improved the condition that an amount of fresh air aspirated into a combustion chamber 7 of the cylinder 4 is insufficient compared to that aspirated into the second cylinder having the suction valve 13 which opens and closes in a range of low rotational speeds of the engine, and an output of the engine is increased.

Title: Feeder for sealing oil
Inventor: IZAWA MASAAKI
IPC: F16N7/40
Filed: 1980-09-18
Abstract: PURPOSE:To prevent the sudden inflow of hydrogen gas and moisture in a hydrogen gas drier into a vacuum tank by each mounting a throttling device to a piping section passing between said drier and a vacuum pump and a check valve between the vacuum tank and the vacuum pump. CONSTITUTION:Wet hydrogen gas is circulated in the hydrogen gas drier 5 at all times. When the gas is absorbed to a desiccant and brought to a saturated condition, valves 6, 7 are closed completely. When a valve 8 is opened completely, the wet hydrogen gas in the hydrogen gas drier 5 passes in a pipe 24-th throttling device 15-a pipe 25, is sucked by means of the vacuum pump 13 and is discharged to the atmosphere. On the other hand, there is a danger that the wet hydrogen gas flows into even the vacuum tank 12 because the throttling device is also communicated with the vacuum tank 12. When the valve 8 is opened completely, the flow rate of the wet hydrogen gas is limited by means of the throttling device 15 while the inflow of the gas into the vacuum tank 12 is prevented by means of the check valve 16.

Abstract: PURPOSE:To extract only a true signal component by obtaining a difference between a result of integer multiple of an output of the 1st CCD image sensor and an output of the 2nd CCD image sensor by means of a difference device. CONSTITUTION:The energy of a signal charge of a picture element Gi of a pick up section CCD 10 is increased by Di through the reception of light in the process of frame transfer up to a image element Hi of a storage section CCD 20. The output of an amplifier 7, Xi is expressed as Xi=2(Gi+Di). Moreover, the signal charge of the image element Hi corresponding to the CCD image sensor of the storage section of the CCD image sensor 4 is doubled for a false signal only with respect to that of the CCD image sensor 3, because the frequency of the frame transfer drive signal is a half that of the CCD image sensor 3. Thus, the signal charge Yi of the image element Hi of the CCD image sensor 4 is expressed as Yi=Gi+2Di and the output Zi of a difference device 8 is expressed as Zi=Xi-Yi=Gi. Thus, the correct video signal is obtained from the output of the difference device 8.
