Title: Closed loop circuit
Inventor: SHIMA AKIRA
IPC: G05D3/12
Filed: 1987-07-09
Abstract: PURPOSE:To avoid such an accident where the positive feedback is applied by mistake and a motor has the runaway by operating the motor after switching a position loop to a speed loop and deciding whether the feedback caused by a feedback signal received from a detector is positive or negative. CONSTITUTION:A speed command is delivered from a variable resistor 18 after a switch 19 is set at the speed loop side and a motor 7 is driven via a servo amplifier 8. In this case, a major roll 13 is driven when the motor 7 is driven forward and then the A-phase and B-phase signals are fed back from an encoder 10. When the A-phase signal is advanced by 90 deg. compared with the B-phase signal, a forward rotation pulse is outputted from a pulse branching circuit 14 and supplied to the DOWN side of an up-down counter 4. At the same time, a clear signal is supplied to a flip-flop 16. Thus an LED 17 is turned on. In such a constitution, the negative feedback is confirmed so that the runaway accident of the motor 7 can be avoided.

Title: Hdlc transmission system
Inventor: SHINKI TAKASHI
IPC: H04L12/70
Filed: 1979-12-26
Abstract: PURPOSE:To eliminate an influence of variance in processing time due to fluctuations of the load on a processor, by setting a packet end command on the completion of DMA transfer of a packet through hardware without reference to the  processor. CONSTITUTION:Memory 1 is stored with data to be transmitted in a packet and a command indicating the end of the packet. In data transfer, HDLC circuit 5 outputs a transmission request REQ signal to direct memory access (DMA) control circuit 6. Circuit 6, when the data transfer is held in readiness, returns an acknowledge (ACK) signal to the HDLC circuit and reads transmitted data, byte by byte, out of memory 1 in DMA mode to send them to circuit 10 via register 4. Circuit 6 counts the number of bytes of the transmitted data and, when going up to a prescribed number, sends the command signal to timing circuit 8. Consequently, circuit 8 generates an END signal and permits selector 2 to select register 9, transmitting FCS and an end flag from memory 1 via HDLC circuit 5.

Abstract: PURPOSE:To allow high precision focal point detection by setting the spectral characteristics of th dielectric multi layer film provided on a half mirror plane when introducing luminous flux, which passed through the separated plural pupil regions of an objective lens, to a focal point detecting device through the half mirror plane inclined in a prescribed direction. CONSTITUTION:The pupil of the objective lens 1 is separated into the plural regions, for example, two regions and the light quantity distributions regarding two object images are formed by using the luminous flux which passes through each region, and the relative positional relation of the two light quantity distributions are obtained. At the time, the luminous flux from the objective lens 1 is introduced to the optical means through the half mirror plane 9a composed of the dielectric multi layer film positioned with the inclination against the separating direction of the pupil of the objective lens. The dielectric multi layer film is composed so as to pass through the objective lens 1 within the wavelength region which detects focusing condition and to possess almost flat spectral characteristics within the incidence angle to the half mirror plane 9a of the luminous flux introduced to the optical means. Thus, the light quantity distribution regarding the substance image is formed precisely on the plane of a photodetector string, and the focal point detecting precision is improved.
