An exposure control apparatus of a camera includes a first switch which can select a plurality of drive modes including an auto-exposure bracket mode (AEB mode), a second switch which issues signals when operated, a third switch which can modify an exposure correcting value and a memory which stores a plurality of predetermined exposure correcting values. A drive mode selector successively selects the drive modes in response to signals from the second switch when the second switch is actuated during the operation of the first switch. A modifying device successively selects an exposure correcting value to be used to correct the exposure value among those stored in the memory in response to signals issued from the second switch when the latter is actuated during the operation of the third switch. A photographing controller is provided which takes a plurality of pictures at different exposure values in an exposure width correcting values selected by the modifying device when the AEB mode is selected.

A logic circuit having a diagnostic function is disclosed in which each of first latches for applying data to combinational circuits included in the logic circuit and/or receiving data from the combinational circuits is provided with a second latch and a selector for selecting the output of the first latch in a first mode and for selecting the output of the second latch in a second mode. In a regular operation, the output of the first latch is never transferred through the second latch, and the selector is operated in the first mode. Accordingly, the output of the first latch is supplied directly to a succeeding combinational circuit, and thus the delay caused by the second latch in the prior art can be eliminated. Although the delay caused by the selector is unavoidable, this delay can be made far smaller than the delay caused by the second latch. In a diagnostic operation, the output of the first latch is transferred through the second latch, and the selector is operated in the second mode, in order to perform the diagnostic operation stably even when data is transferred between first latches having the same phase, or the logic circuit includes a one-latch loop.

A system for lubricating a 4-cycle engine includes a crank chamber having a crank portion of a crankshaft contained therein and storing a lubricating oil therein, a valve operating chamber having a valve-operating device contained therein, wherein the crank chamber and the valve-operating chamber are provided in an engine body. An oil mist producing means is provided in the crank chamber for producing an oil mist from the lubricating oil. The crank chamber and the valve operating chamber are in communication with each other above an oil level of the lubricating oil in the crank chamber through a control valve which is opened upon rising of the pressure in said crank chamber and closed upon reduction of the pressure in said crank chamber. The valve-operating chamber is substantially in communication at its upper portion with the atmosphere, and in communication at its bottom with the crank chamber through an orifice.

An apparatus for producing test data used for detection of defects which occur in manufacturing functional blocks of a processor LSI is provided with a test pattern producing part for detecting a fault of the functional block at a block edge of the functional block, based on logic data of the functional block, with regard to one operation of the processor LSI which operates the functional block for the test data to be produced, the test pattern at the block edge of the functional block being such as to satisfy the conditions of an input signal to the block edge of the functional block when an instruction on the one operation is executed, and the conditions of an output signal from the block edge of the functional block being observable from the outside of the processor LSI when the instruction is executed. The apparatus also has an instruction sequence producing part for producing an instruction sequence in a machine language for the processor LSI by which an output from the block edge of the functional block becomes detectable at an external terminal of the processor LSI.

An oil reservoir chamber, a crank chamber and a valve-operating chamber are provided in an engine body. The oil reservoir chamber and the crank chamber are in communication with each other through a through-hole, and the crank chamber and the valve-operating chamber are in communication with the each other through a one-way valve which is opened upon rising of the pressure in the crank chamber. The valve-operating chamber and the oil reservoir chamber are in communication with each other through an orifice. By utilizing a pressure pulsation in the crank chamber, an oil mist produced in the oil reservoir chamber is circulated from the oil reservoir chamber to the crank chamber, the valve-operating chamber and the oil reservoir chamber. Thus, in any operational attitude of an engine, the lubricating oil can be circulated without use of special oil pump.

An electronic flash illuminates an object. A first photometric unit measures a visible light component of ambient light of the object. A second photometric unit measures an infrared light component of the ambient light of the object. A determining unit determines the ratio between the visible light component measured by the first photometric unit and the infrared light component measured by the second photometric unit. On the basis of the ratio determined by the determining unit, a light emission determining unit determines whether the electronic flash is to be made emit light.

A shutter speed setting apparatus is provided which is arranged to respond to a main capacitor charge completion signal to judge whether or not the set value of a shutter speed S is higher than a flash synchronization speed S.sub.0. If it is judged that the set value of the shutter speed S is higher than the flash synchronization speed S.sub.0, the set value of the shutter speed S is temporarily stored in the form of a value M and the set value of the shutter speed S is forcibly rewritten with a given speed not higher than the flash synchronization speed S.sub.0. After the main capacitor charge completion signal has disappeared, the set value of the shutter speed S is again rewritten with the temporarily stored value M. If an up/down switch is operated so as to decrease the shutter speed, the set value of the shutter speed S is decreased from the shutter speed which is forcibly rewritten.
