Abstract: PURPOSE:To suppress emission of NOx without causing the worsening of combustion efficiency, by slightly closing a valve provided to an exhaust system at operation below an intermediate load and forcibly feeding a part of exhaust gas under a higher pressure into a cylinder proceeding to a compression stroke. CONSTITUTION:An exhaust brake valve 4 provided between an exhaust manifold 2 and an exhaust pipe 3 of an internal-combustion engine 1 is slightly closed under an operative condition, in which sufficient exhaust pressure is not obtained, for instance, at operation below an intermediate load, and a part of exhaust is forcibly fed into a cylinder immediately after an intake stroke.

Accordingly, the exhaust gas is recirculated without causing the worsening of combustion efficiency, and emission of NOx to the air can be suppressed.

Title: Dark current controller for solid-state image-pickup device and still video camera
Inventor: TAKAYAMA ATSUSHI
IPC: H04N5/335
Filed: 1997-03-25
Abstract: PROBLEM TO BE SOLVED: To allow the generation of dark current at a solid-state imaging device to be at a low level which is lower than a fixed limit by performing control, so as to reduce the power consumption of equipment intergrated together with the solid-state imaging device corresponding to a dark current level detected by a dark current detecting means. SOLUTION: Based on the temperature of a CCD 104 detected by a temperature sensor 201 and the storage time measured by a timer 202, the dark current level of CCD 104 is detected. The more a dark current generation level is increased, the less power consumption for a liquid crystal display part 131 is decreased, and a heating value is decreased. Otherwise, the clock of a clock generator is decreased (a frequency is decreased, while fixing the width of drive pulse or the drive pulse is decreased while fixing the frequency) and the control program of the main CPU 110 is set so as to reduce power consumption in the whole circuit. Since the power consumption on the liquid crystal display part 131 is relatively large, the control of this power consumption is effective for decreasing the dark current.

Title: Water level sensor
Inventor: MURAKAMI KOJI
IPC: G01F23/26
Filed: 1989-03-27
Abstract: PURPOSE:To make it possible to detect a water level simply and highly accurately at a low cost by sealing a conductor film with sheet shaped waterproof film, and winding the film around the outer surface of a pipe body. CONSTITUTION:A pair of conductor films 11 which are sealed with a waterproof film 9 are wound and fixed around the outer surface of a pipe 7. A pair of conductor films 11 are provided so as to face each other. When liquid in a water tank 1 is intruded into the pipe 7, air or the intruded liquid is present between the pair of the facing conductor films 11 in addition to the waterproof film 9 and the insulating pipe 7. Since the dielectric constants of the air and the water are different, the capacitance between the par of the facing conductor films 11 is changed when the water level between the pair of the conductor films 11 is changed. When the change in capacitance is converted into, e.g. a voltage or frequency, the water level can be detected. Thus, the water level can be detected simply and highly accurately at a low cost.
