A car and a counterweight are suspended by a main rope that is wound onto a driving sheave, a car suspending sheave, and a counterweight suspending sheave. A first main rope portion between the driving sheave and the car suspending sheave and a second main rope portion between the car suspending sheave and the car-side rope fastener portion are passed through a common car-side penetrating aperture so as to cross each other when viewed in an axial direction of the driving sheave. A third main rope portion between the driving sheave and the counterweight suspending sheave and a fourth main rope portion the counterweight suspending sheave and the counterweight-side rope fastener portion are passed through a common counterweight-side penetrating aperture that is disposed on the machine room floor so as to cross each other when viewed in the axial direction of the driving sheave.

In a camera system according to the invention, a camera body and an interchangeable lens have respective identification data tables that are congruous with each other. As an appropriate data address is indicated to the interchangeable lens by the camera body, an identification data that is stored in the identification data storage section and corresponds to the indicated address is transmitted from the interchangeable lens to the camera body. The identification data judging section of the camera body compares the identification data transmitted back from the interchangeable lens and the identification data that is stored in the identification data storage section and corresponds to the address. As a result, it is determined if the dedicated accessory device is mounted on the camera body or not.

A seal structure in an engine, including a seal member interposed between a cylinder head having a slanting face portion at least at an intermediate portion of its upper end face to which a valve-operating cam chamber opens, and a head cover coupled to the upper end face of the cylinder head by a bolt to close the valve-operating cam chamber. The head cover has a fit wall portion formed thereon and fitted to an inner peripheral surface of the valve-operating cam chamber, and the seal member is mounted in a seal groove provided in an outer peripheral surface of the fit wall portion to come into close contact with an inner peripheral surface of the cylinder head. Thus, an interference can be provided equally at various portions of the seal member irrespective of the number of bolts used, and the seal member can always exhibit a good seal function.

In a valve-operating mechanism in a 4-cycle engine, a timing transmitting device is disposed on one side of an engine body. A cam device includes a cam coupled to a driven pulley of the timing transmitting device on one side of a cylinder head, intake and exhaust rocker shafts rotatably carried in the cylinder head, intake and exhaust cam followers secured to one ends of the rocker shafts with their tip ends in sliding contact with the cam, and intake and exhaust rocker arms secured to the other ends of the intake and exhaust rocker shafts with their tip ends abutting against the intake and exhaust valves. Thus, the cam of the cam device can be disposed on one side of the cylinder head to effectively reduce the entire height of the engine.

In a handheld type four-cycle engine, the lubricating system includes an oil tank placed outside an engine main body, a through hole providing communication between the oil tank and a crank chamber, an oil feed pipe placed outside the engine main body and providing communication between the crank chamber and a valve operation chamber of a cylinder head, an oil return pipe placed outside the engine main body and providing communication between the valve operation chamber and the oil tank, and a one-way valve for transferring oil from the crank chamber to the valve operation chamber side via the oil feed pipe. The side walls of the engine main body can thus be made thinner and the weight of the engine main body can therefore be reduced regardless of the presence of the oil feed pipe and the oil return pipe.

An apparatus for providing 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 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. The controller also interrupts photographing when a release switch is turned OFF.
摘要:
An electronically controlled camera having a zoom lens has an operational member for driving the zone lens between a tele position and a wide angle position. The zoom lens is moved toward the tele position when the operational member is moved in a normal direction. The zoom lens is moved toward the wide angle position when the operational member is moved in the reverse direction. A taking mode changing mechanism changes taking modes. A display device displays a taking mode. A control mechanism changes the taking mode to another taking mode when the taking mode changing mechanism is operated. A setting time changing device changes the setting time of a manual shutter (or interval) to another setting time under predetermined conditions when the camera is set in a manual shutter mode (or interval) and both the operational member and the taking mode changing mechanism are operated.

An electronically controlled camera having a zoom function for changing a focal length of a taking lens and a manual function which is able to select the shutter speed by the manual operation when the camera is in a manual mode, shutter speed automatic changing apparatus automatically changes the shutter speed in the direction for reducing the changing amount of the Full-open Aperture F-number which is changed in accordance with the change of the focal length so that the exposure value becomes a predetermined value in accordance with the reference shutter speed at a time when said reference shutter speed is selected in the manual mode and said focal length is changed by said zoom function.
