Title: Vehicle tread adjusting device
Inventor: IWAMOTO MASATOSHI
IPC: B60B35/18
Filed: 1989-12-13
Abstract: PURPOSE:To provide complete locking for hydraulic cylinders and prevent any accidental tread change by disposing plural double pilot type check valves between the hydraulic cylinders which expand and contract axle cases and plural change-over valves which control the cylinder. CONSTITUTION:For controlling a tread, a right/left change-over valve 78 is changed over to select either of right or left hydraulic cylinder 64, and at the same time, a change-over valve 79 is changed over to a tread adjusting side to connect it to the right/left change-over valve 78. A directional change-over valve 77 is changed over from neutral position to expanding side, for example. The pressurized oil from a hydraulic source 76 is fed to a circuit 80 through the above respective valves 77, 79, 78, and then enters one oil chamber 72 of the hydraulic cylinder 64 through a check valve 83. On the other hand, a check valve 84 on the opposite side opens by the pressurized oil coming to a circuit 81, so that the oil in the other oil chamber 73 is returned. As a result, the hydraulic cylinder 64 expands. Then respective check valves 83, 84 close to shut down pressurized oil in the respective oil chambers 72, 73. It is thus possible to prevent any accidental tread change.

Filed: 1987-12-21
Abstract: PURPOSE:To execute a rational and efficient connecting work by heading and melting each end part of an optical fiber, pushing them in the abutting direction and bringing them to welding connection, and immediately thereafter, measuring the outside diameter of the connecting part and deriving a ratio of the minimum value of its outside diameter and a value of the outside diameter of the optical fiber which is not heated. CONSTITUTION:Each end part of optical fibers 1, 1 is opposed at a prescribed interval and heated and melted, pushed in the abutting direction and brought to welding connection, and immediately thereafter, the outside diameter of the connecting part is measured, the minimum value (d) of the outside diameter is derived, and a ratio d/D of said value and a value D of the outside diameter of the optical fiber which is not heated is derived. Accordingly, as for the optical fiber whose outside diameter ratio d/D is <='1', it can be estimated that its connection loss is large. In such a way, by only measuring the outside diameter ratio immediately after the optical fiber has been pushed in, a connection failure can be estimated, and even in an optical fiber laying job site, the work can be executed efficiently.

Filed: 1989-12-15
Abstract: PURPOSE:To save the number of components of the circuit and to simplify the circuit by driving a switch means switching the gain of a gain correction circuit to a prescribed value with the output of a control means. CONSTITUTION:A circuit 50 detects the output equivalent voltage of picture tube derive circuits 19R, 19G, 19B at a black level reference insertion pulse period and comparators 52R, 52G, 52B go to a high level output when the voltage reaches a prescribed value or over. In this case, the output of hold means 59R, 59G, 59B goes to a high level and switch means S4r, S4g, S4b are respectively switched to select the position of earth and gain correction circuits 181R, 181G, 181B are operated at a minimum gain and the drive voltage of the cathode is minimized. Thus, since one control system is enough to suppress a drive voltage of the picture tube drive circuits 19R, 19G, 19B of black level and white level, an excessively biased picture tube is surely prevented at application of power with the circuit comprising less component number.

Filed: 1990-11-27
Abstract: PURPOSE:To shorten the time when the operation of a CPU is impossible by providing a buffer memory between a DMAC and a 1st memory and performing the burst transfer to the 1st memory. CONSTITUTION:A FIFO (first-in/first-out memory) 04 is provided between a DMAC 02 and a memory 03. At the same time, a burst control 05 is provided between a CPU 01 and the DMAC 02 so that the burst transfer is carried out between the FIFO 04 and the memory 03 under the control of the CPU 01. Then the DMAC 02 performs the DMA transfer of data related to the burst transfer between a transfer partner device 06 of the memory 03 and the FIFO 04 under the control of the circuit 05. As a result, the CPU 10 can be active during the transfer of data requiring a long time carried out between the device 06 and the FIFO 04 under the control of the DMAC 02. Thus the CPU 01 is kept inactive only in the period of the burst transfer and the inactive time of the CPU 10 can be minimized.
