    • In an electronic flash unit capable of being coupled to a camera body including a mounting section and an operating dial which can be rotatively operated to a predetermined position to set information regarding exposure factors and can be fixed at the predetermined position, the electronic flash unit including a support member having a mounting section engageable with the mounting section of the camera body, a transmitting member displaceable to a position responding to the predetermined position of the operating dial depending upon the engagement of the two mounting sections, and an electric circuit for controlling flash light emission, there is provided converting means for converting the information into electrical signals and introducing the same into the electric circuit. The converting means includes contact sections capable of contacting each other and secured to at least two spatially different regions relatively variable in position by the displacement of the transmitting member.

    • A semiconductor device includes a first latch unit that latches write data based on a strobe signal, a second latch unit that receives the write data latched in the first latch unit based on a first clock signal, and a strobe generation unit that generates the strobe signal and supplies it to the first latch unit. The strobe generation unit includes a bit shift counter, which receives a second clock signal and outputs a bit shift signal having a logic level that is inverted every plural clock cycles of the second clock signal, and a logic gate that outputs the second clock signal as the strobe signal according to the bit shift signal. The latch period of the write data in the first latch part is determined by the period of the strobe signal and also the period of the bit shift signal.
    • 半导体器件包括:第一锁存单元,其基于选通信号锁存写入数据;第二锁存单元,其基于第一时钟信号接收锁存在第一锁存单元中的写入数据;以及选通产生单元,其生成选通信号 并将其提供给第一锁存单元。 选通产生单元包括位移计数器,其接收第二时钟信号并输出​​具有在第二时钟信号的每多个时钟周期被反相的逻辑电平的位移信号,以及输出第二时钟信号的逻辑门作为 根据位移信号的选通信号。 第一锁存部分中写入数据的锁存周期由选通信号的周期以及位移信号的周期确定。
