摘要:
In an automatic brake controller having a vehicle velocity detector for detecting vehicle velocity and a wheel velocity detector for detecting wheel velocity, a failure detecting system is provided for the vehicle velocity detector and the wheel velocity detector. A comparator which makes a comparison between the vehicle velocity signal obtained from said vehicle velocity detector and the wheel velocity signal obtained from said wheel velocity detector generates a predetermined output signal when the difference between both the output signals of said detectors exceeds a predetermined value, and a logical circuit is responsive to said output signal from said comparator to provide a failure signal when a signal representative of a normal transit condition is being generated.

Disclosed is a split engine control system wherein the intake manifold is segmented by a shut-off valve into a first chamber portion leading to a first group of cylinders and a second chamber portion leading to a second group of cylinders. During periods of relatively low load, the cylinders of the second group are deactivated and the shut-off valve is closed to isolate the second chamber from the first chamber to cut off air supply to the deactivated cylinders. Exhaust gases are recirculated through the deactivated cylinders so that their pumping loss is minimized. A pressure detector is provided to detect a pressure difference which might develop between the first and second chambers during the partial cylinder operation to control the flow rate of the recirculated gases until the pressure difference reduces substantially to zero.

A printer system containing an elastic endless sheet member which extends between roller members in front of a print head. The roller members are disposed so as to form a flat surface of the elastic endless sheet member in front of the print head in order to ensure clean printing. One of the roller members is connected to a paper feed motor so that a paper sheet is fed in front of the print head in the vertical direction in unison with the rotation of the elastic endless sheet member around the roller members.

Disclosed is a heat-transfer type thermal recording device capable of recording/printing color pictures by heating an ink tape using a thermal line head and transferring ink from the ink film tape to a continuous sheet of recording paper where the ink film tape and recording paper are conveyed simultaneously, consisting of a vertical cassette unit with an ink-tape supply reel and a take-up reel which allows both to freely rotate by suspending them between two side panels of the cassette unit, with such a configuration in which the ink tape from the supply reel is continuously retrieved by the take-up reel through an inferior aperture in the cassette unit after the ink tape is drawn through a superior aperture in the cassette unit. The cassette unit is installed in a designated position inside the thermal recording device to enable easy loading and unloading and to simplify positioning of the ink film tape between the thermal line head of the recording device and the recording paper platen reel.

In a multi-cylinder fuel injection type internal combustion engine, apparatus is provided for successively inactivating one or more cylinders of the engine by inhibiting the injection pulses supplied to the fuel injection units in response to a sensed engine load. The apparatus includes a forward-backward counter which operates in downward count mode to decrease the number of active cylinders when light load is sensed and in forward count mode to increase the number of active cylinders when heavy load is sensed. A ring counter is provided to generate recylically occurring pulses on its output terminals equal in number to said cylinders successively in response to the occurrence of each injection pulse. A logic circuit is connected to the ring counter to generate injection inhibit pulses equal in number to the inactive cylinders.

A control system for a multi-cylinder internal combustion engine comprises a split engine control unit for operating the engine on partial cylinders when reduced engine power can adequately operate the vehicle, and first and second upstream exhaust conduits for directing exhaust gases from first and second group cylinders respectively to a common junction to which a downstream exhaust conduit is connected for emitting the gases to the atmosphere. A first set of an exhaust gas sensor and catalytic converter is disposed in the first conduit to be exposed to the stream of gases exhausted from the second group cylinders which are activated at all times and a second set of an exhaust gas sensor and catalytic converter is disposed in the common downstream conduit to be exposed to the stream of gases exhausted from the first group cylinders directed through the first conduit and to the gases passed through the upstream catalytic converter in the second conduit. A feedback control circuit is responsive selectively to a signal from the first gas sensor during the partial cylinder operation for correcting the mixture ratio to a rich side of stoichiometry to promote reduction of the NOx component in the upstream converter and oxidation of HC and CO components in the downstream converter, and to a signal from the second gas sensor during the full cylinder operation for correcting the mixture ratio to a point at or near stoichiometry to promote simultaneous reduction and oxidation processes in both of the converters.

Disclosed is an image data transmission apparatus which includes an image reading unit for reading the original image, and a transmission apparatus main body. The main body includes a memory for storing the image data read by the image reading unit and transmits the content of the memory. The image reading unit is detachably mounted on the transmission apparatus main body. The transmission apparatus main body is further provided with a conveying device for conveying the original in a state in which the image reading unit is mounted on the transmission apparatus main body to thereby read the original. The image reading unit may also scan the original to read an original image, in a state in which the image reading unit is dismounted from the transmission apparatus main body. Further, a sheet element made of a material of a low coefficient of friction, as opposed to the original, may be disposed at a position corresponding to the mounted state of the image reading unit on the transmission apparatus main body. Further, an image data transmission apparatus is disclosed which possesses the telephone function and copy function, and is also provided with, as desired, a facsimile function by mounting a detachable facsimile processing device in the transmission apparatus main body. Further, the operation panel may be, in order to use it as the original stacker, disposed angularly dislocatably around the axial line crossing with the original inserting direction.
