Title: Bus control system
Inventor: NOMURA KEIICHI
IPC: G06F13/362
Filed: 1987-05-28
Abstract: PURPOSE:To improve the availability of buses by providing a control line showing the type of a bus access on a common bus and changing the bus priority according to the state of the control line when the bus requests are produced at one time from plural bus masters. CONSTITUTION:A control line showing the type of a bus access is provided on a common bus in addition to the bus request signal received from a bus master. The bus priority is changed according to the state of the control line when the bus requests are produced at one time from plural bus masters. For instance, the bus requests are given at one time from a DMA controller 7 and a CPU 2. In such a case, a bus grant is first given to a memory and then to an I/O after a memory bus cycle is set. Thus an I/O bus cycle is set. A bus arbiter 11 delivers a bus grant to the CPU 2 regardless of the bus request level when the CPU 2 activates a command status simultaneously with a bus request in an emergency state. Thus the system efficiency is improved.

Abstract: PURPOSE:To permit highly accurate positioning control, by a method wherein a positioning control signal is supplied to a fixing unit together with a driving signal while the driving signal is controlled in accordance with induced signal induced by the positioning control signal. CONSTITUTION:A minute AC constant current, having a frequency sufficiently larger than the responsable frequency of a movable piece 4, is superposed from an AC constant current source 6 on a driving current supplied from a stepping motor driving circuit 5 to coils 2, 3. The minute AC constant current does not affect the movement of the movable piece 4 but generates an AC voltage proportional to the inductances of the coils 2, 3. The voltage signals Va, Vb, generated in the coils 2, 3, are compared and operated in an operating circuit 10 to control the balance of the driving current supplied from the stepping motor driving circuit 5 to the coils 2, 3, so as to nullify the difference of the voltages.

Abstract: PROBLEM TO BE SOLVED: To provide a power supply device that achieves AC output regardless of relatively small number of elements, achievers a high input power factor and a low harmonic distortion, and has a high conversion efficiency. SOLUTION: A series circuit of a capacitor C1 and a smoothing capacitor C0 is connected between the output terminals of a rectifier DB for performing the all-wave rectification of an AC power supply AC.

Therefore, by switching a potential V3 at the output terminal of the voltage generation means B an AC current is allowed to flow to the load circuit A.  Also, by regulating the voltage between both terminals of the capacitor C1 by the switching element SW1 , an input current can be controlled to be proportional to the input voltage.

Title: Focus detecting device with auxiliary lighting device
Inventor: ISHIBASHI KENJI
IPC: G03B3/00
Filed: 1986-06-09
Abstract: PURPOSE:To eliminate unnecessary distance measuring operation, inhibit light from being emitted fruitlessly, and to save electric power by inhibiting subsequent searching operation from performed and auxiliary light from being emitted when a search means decides that focus detection is impossible. CONSTITUTION:In case a conversion coefficient K for converting the quantity of defocusing of a zoom lens into the rotating speed of a motor is large, the gradient is small as shown by a straight line A3 and the quantity of focus movement of the lens per time is small, so overlap parts among distance measurement ranges DFE1-DFE3 of distance measurement at points tc1-tc3 of time become large. Namely, the distance measurement range DEF2 is not necessary specially and a object is never missed even when a measurement of distance is not taken at the point tc of time. When the conversion coefficient is large, the focus of the lens is moved by a constant quantity and next distance measuring operation is started. Consequently, the number of times of the emission of the auxiliary light can be decreased without forming any area where the distance measuring operation is impossible, power consumption due to lighting is reduced, and the number of times of giving a person as the object a glare is reduced.
