Title: Contactless displacement sensor
Inventor: UEDA MASANORI
IPC: G01D5/18
Filed: 1990-03-14
Abstract: PURPOSE:To detect the quantity of position displacement and the quantity of angular displacement at the same time by one sensor by modulating magnetic fields which are produced by two magnets with different frequencies, and detecting the resistance variation of a magneto-resistance element as voltage variation. CONSTITUTION:The leak generated when pieces of main magnetic flux from a couple of fixed magnets 51 and 52 pass magnetic metal pieces 53 and 54 intersects a sense current is flowing in an MR element 61 at right angles, and its extent is maximum nearby the magnets 51 and 52 and minimum almost in the middle between the magnets 51 and 52. When a sensor part 55 is moved toward the magnet 51, a 1st magnetic field B51 operating on the element 61 increases, so the resistance value of the element 61 varies. Consequently, the quantity of variation in the relative position between a magnetic circuit 50 and the sensor part 55 is detected as variation in resistance value. When a frequency-modulated exciting current is supplied to electromagnets 57 and 58 on the sensor part 55, the electromagnets 57 and 58 are changed in polarity alternately every second and pieces of magnetic flux which change in direction with frequency are produced from those magnetic poles.

Abstract: PURPOSE:To smoothly perform the change-over from rate control in the injection step to pressure control in the follow-up pressure, by inputting an output signal from a previous amplifier selectively into a torque motor to control the rate of a screw and the pressure of the injection cylinder. CONSTITUTION:In a hydraulic controlling valve a, by driving a power amplifier b, the opening between a port P and a port B, and the port B and a port T, that is, the opening of throttles C3, C4 can be varied, and thus the controlled hydraulic pressure is led from the port B to an injection cylinder g to drive the screw j. When the rate control is required, the control mode change-over switch h has been switched to be connected to the previous amplifier c in advance. The hydraulic oil entered into the port P of a hydraulic controlling valve a from a main hydraulic source i is divided into a hydraulic stream that flows from the port T to a tank m and a hydraulic stream that flows from the port B to the injection cylinder g. Accordingly when the torque motor M of the hydraulic controlling valve a is driven by the power amplifier b, the displacement rate of the screw j connected to the injection cylinder g can be varied.

Title: Log data storage device
Inventor: ICHIKAWA MASAKAZU
IPC: G06F3/06
Filed: 1996-03-21
Abstract: PROBLEM TO BE SOLVED: To surely leave fault information in a log medium by repeating rewrit ing after insertion into a normal log medium even if the storage of fault informa tion into the log medium has failed. SOLUTION: When a diagnosis processor 2 detects the occurrence of the fault of a processor 1, it stores fault information into a self RAM area and writes it into a log medium 8 during mounting. When writing fails, an FD control circuit 3 leaves a 'failed' result in an FD write result storage circuit 6. When an FD write retry control circuit 5 detects 'failure', it issues the exchange request of a log medium 4 and a command for retrying writing to the diagnosis processor 2. The diagnosis processor 2 displays 'log medium exchange' on LED on a control panel 7. When the medium is exchanged into a normal log medium 9, display disappears and the diagnosis processor 2 writes fault information stored in the RAM area into the normal log medium 9 with the matching of the attention of log medium exchange and the write retry command.
