Therefore it is the object of the present invention to provide a lighter with a safety device, in which the lighter is locked after each use, so that unexpected disaster can be prevented. In achieving the above object, the lighter according to the present invention is characterized in that a pressing button for activating a piezo electric device is prevented from being activated by a locking section, the locking section being for temporarily locking an igniting section. The locking section is activated by the pressing button and a locking member.

Abstract: Apparatus for controlling a load connected to an internal combustion engine during operation is disclosed and claimed. The apparatus comprises a suction switch (12) which is sensitive to a decrease in vacuum in the manifold (16) of the vehicle when more motive power is required. The switch (16) causes a controller (30), at terminal (44) thereof, to provide a voltage higher than a predetermined set voltage at the D+ terminal of a conventional regulator (46), thereby to interrupt current flow in the excitation circuit of a conventional alternator (48). The alternator is consequently switched off to reduce the load connected to the engine, thereby to make more engine power available to the drive wheels of the vehicle. The apparatus thus also serves as a fuel saving device.

Abstract: A sampling cylinder 3 is attached to a process piping 2 through which a slurry flows. A front piston 9 and a rear piston 10 which slide within the sampling cylinder 3 are driven via a driving rod 12 by a fluid pressure cylinder 11. These two pistons 9,10 are allowed to slide to collect the slurry into a sampling space 30 defined between the pistons 9,10. The front piston 9 is brought closer to the rear piston 10 to reduce the volume of the sampling space 30. Thus, only the filtrate in the slurry is fed through a filter 5 into a filtrate collecting tank 6, where pH etc. of the filtrate is measured by a sensor 8. Subsequently, the front piston 9 is brought apart from the rear piston 10 to increase the volume of the sampling space 30. Thus, the filtrate is returned into the sampling space 30 back-washing the filter 5. Then, the slurry in the sampling space 30 is returned to the process piping 2.
