Title: Electrically driven diaphragm driving device
Inventor: YOSHINO TSUNEMI
IPC: G03B9/02
Filed: 1980-06-17
Abstract: PURPOSE: To provide an electrically driven diaphragm driving device of high reliability and a small size by using an element, such a piezoelectric substance or dielectric, which exhibits electrostrictive characteristics when applied with an electrical signal as driving force for said device.  
     CONSTITUTION: Diaphragm blades 1 and an operating ring 4 are superposed in this order on a stationary ring 3, whereby an iris diaphragm is constituted. When the ring 4 is rotated in an arrow (a) direction, the blades 1 also rotate in the same direction as the arrow (a) while the projections 1a are slipping in guide grooves 5 around the center, thereby assuming a stopped down state covering a disphragm aperture 2. Now, when electric power is supplied only to the 1st piezoelectric substance 10, this substance 10 displaces to move the 1st moving member 12, thereby allowing the same to abut on the inside circumferential surface of a stationary barrel 14. The first movement assisting member 6 is fixed between the stationary ring and a stationary barrel by the frictional force generated by the abutment between the 1st movable member 12 and the barrel 14. When electric power is supplied to the 3rd piezoelectric body 16 in such a state, the 2nd movement assisting member 17 which is not supplied with power and is in a free state is rotated in the arrow (a) direction.

IPC: G06F13/38
Filed: 1985-04-18
Abstract: PURPOSE:To write the control data given from a CPU at an optional time point by providing a buffer memory and a transfer control circuit to the processor of a host containing a CPU and also setting plural registers at an external equipment in response to each address of the buffer memory. CONSTITUTION:When the output data ADB of a counter 30 are turned into the data of three addresses, the output PI of a coincidence detecting circuit 35 is set at a low level. The output of a latch circuit 36 is set at a low level later than the output PI by one cycle of a clock pulse CK. Then the counting action of the counter 30 is stopped by the output PI and the data ADB is kept as it is until it is preset at a start address by the start pulse ST in the next vertical blanking period. This data transfer action is carried out in about 1mu sec from the time point of the front edge of a vertical synchronizing pulse VD and is through while a CPU 10 is detecting the pulse VD. Thus the control data given from the CPU can be written to the equipment to be controlled at an optional time point.
