Title: Focus servo controller
Inventor: FUKAZAWA TAKASHI
IPC: G11B7/085
Filed: 1989-06-06
Abstract: PURPOSE:To surely focus an objective lens to the recording surface of an information recording medium by providing a blanking pulse generating circuit for generating a blanking pulse synchronizing with a search signal. CONSTITUTION:A blanking pulse generating circuit 12 sends out a blanking pulse to a zero crossing detector 10, while the blanking pulse synchronizing with a search signal, that is, an objective lens is driven in the direction being adjacent to an information recording medium 1. While this blanking pulse is going sent out, an operation of the detector 10 is stopped. Accordingly, the detector 10 is operated in the case the objective lens is driven in the direction going away from the recording medium 1, and also, when a first signal is inputted. This first signal always becomes a focus error signal, therefore, it can be prevented that the objective lens is focused erroneously to the reverse side 3 by a signal being similar to a focus error signal generated by a reflection from the reverse side 3 of the recording medium 1 as in a conventional device.

Title: Time division channel control system for digital exchange
Inventor: IKEMORI KIMIO
IPC: H04Q11/04
Filed: 1985-06-28
Abstract: PURPOSE:To remove the occurrence of singing or interference at a time division path temporarily generated after detecting the interruption of DC loop by sending compulsorily a digital signal corresponding to the zero input value of an analog signal to a corresponding time division channel fro a time until a termination instruction is given to an AD conversion means after the detection of the interruption of the DC loop. CONSTITUTION:A time division channel control circuit 8 is added between an interface part 5 and a time division call equipment 24A. Assuming that each circuit is operated setting 'L' level as active, the status detection signal of the DC loop in a channel corresponding to a communication terminal 2-1 is at 'L' level when the terminal in communication status. Also, the completion of a communication operation at the terminal 2-1 and the interruption of the DC loop are detected with a BORSHT circuit 3-1 and a control signal line 21-1 is immediately inverted to 'H' level. Thus, an exchange control equipment 6 gives the termination instruction to a digital converter 4-1 with setting a control signal line 23-1 at 'H' level, but for the time until the termination instruction is outputted, the output signal of a AND gate 70-1 is kept at 'H'.

Title: Initial program loading control system
Inventor: SERIKAWA HIDEHIKO
IPC: G06F9/445
Filed: 1981-09-11
Abstract: PURPOSE:To allow a channel device to require neither extra circuits nor processing time for initial program loading, by providing a CPU with simple instructions for testing a subchannel state. CONSTITUTION:A subchannel test instruction TSUB consisting of a command code, a channel device number, and an I/O device number is generated by a CPU to check the subchannel state which corresponds to a device number specified by the instruction TSUB without reference to the state of a channel. Once initial program loading IPL is indicated, an SVP6 gives an indication for the IPL to the CPU. The CPU sends an input/output starting intruction SIO to a channel device 3 and an I/O. When a specified channel and the I/O start normally, the instruction TSUB is started for the channel and I/O and a check on input/output interruption holding conditions by the completion of operation is made. When there is no fault after the completion of operation, the contents of an area of channel state words CSW saved right before an input/output test instruction TIO are reloaded to report the normal completion of the IPL to the SVP.

Title: Fault time control system
Inventor: YOSHIMURA JUNICHI
IPC: G05B7/02
Filed: 1988-06-13
Abstract: PURPOSE:To prevent a system under the control of a CPU from being adversely influenced even if an abnormality occurs in CPU itself by switching the system from an automatic control mode to a manual control mode by means of a CPU abnormality detection signal. CONSTITUTION:When a fault time control signal generation part 4 is in the automatic control mode, the fault time control signal is usually outputted to a controlled system 1 under the control of a CPU control circuit 2. When the abnormality of the CPU control circuit is detected by a CPU abnormality supervisory part 3, the fault time control signal generation part 4 is switched from the automatic control mode to the manual control mode by the CPU abnormality detection signal which the abnormality supervisory part 3 outputs. Thus, the fault time control signal is prevented from being transmitted to the controlled system 1 due to the control of the abnormal CPU, and therefore the system under the control of the CPU is prevented from being adversely influenced even if the abnormality occurs in the CPU itself.

Abstract: PURPOSE:To carry out positioning work of an inspection point precisely and efficiently by computing a next image taking position based on the shift distance of the previous image taking position. CONSTITUTION:A programmer and an inspector give various kinds of commands to a control part through keys of an operation part 22. Based on the various kinds of the commands from the operation part 22, a control part 20 controls operation of each part and at the same time carries out computation for repeat operation and equally dividing operation. A memory part 24 stores the inspection point (the image taking position) instructed by the programmer as an inspection program and at the same time stores the image taking position given from the control part 20. A driving part 23 controls the image taking position and the image taking direction of an image taking part 25 based on an instruction from the control part 20. The image taking part 25 takes images of an object to be inspected and gives obtained image data to a monitor apparatus 21. Since the next image taking position is calculated based on the shifted distance of the previous image taking position, the positioning of the next image taking position can be carried out automatically.
