Patent JP-H0728534-A (JP)
Title: Controller for power converter
Inventor: KAWAKAMI NORIKO
IPC: H02M7/537
Filed: 1993-07-13
Abstract: PURPOSE:To suppress the biased magnetization of a transformer regardless of the DC component generated from the power system side by taking the difference between the primary winding current and the secondary winding current of the transformer and detecting the DC component included in the difference to correct the output voltage command of a power converter. CONSTITUTION:When the winding ratio of the transformer is set to 1 for simplicity, the exciting current of the transformer is equal to the difference between the primary current and the secondary current. Since the exciting current approximately corresponds to the magnetic flux of the iron core of the transformer, the DC component included in the exciting current is detected to estimate the extent of DC biased magnetization. Therefore, the difference between the primary winding current and the secondary winding current is calculated by a subtractor 12, and the DC component is detected by a DC component detector 8, and the output voltage command value from a control circuit 7 is corrected so as to cancel the biased magnetization, thereby suppressing the biased magnetization of the transformer 2. Since the correction is performed by the exalting current, not only biased magnetization due to the DC component included in the output of a self-excited converter 3 but also that due to the DC component transiently included in a power system 1 is corrected.

Title: Bus control system
Inventor: OKAZAWA KOICHI
IPC: G06F13/36
Filed: 1989-07-07
Abstract: PURPOSE:To transfer data among connection devices having different data bus widths with no mutual consciousness of these data widths by using such a data width designating signal line that has a fixed level in an open state to optionally mix those connection devices. CONSTITUTION:At a bus control part 100, a data width designating signal line DT64 is set at the data width other than that which must be supported by all devices set on a bus. The connection devices 101 - 104 which try to transfer data in such data width output the signals having the levels different from those set in an open state to the line DT64 corresponding to the due data width and designate the data width. The devices 101 - 104 that designate the data width knows that they are not supporting the data width designated by the remote side of transfer based on the level set in an open state and can change the data width. Thus it is possible to perform the transfer of data without knowing previously the data widths with each other nor producing the errors due to the difference of data widths.

Abstract: PURPOSE:To prevent the subsidence of the ground by improving the drainage of void water by combining a draining means by which water-permeable granular drainage plates are buried through a banking material consisting primarily of expanded plastics such as expanded styrol, etc., to minimize the banking load, banking, and soft ground. CONSTITUTION:Water-permeable granule drainage plates 3 formed by solidifying spherical granules of expanded polystyrene 15, etc., by an adhesive 6 into a plate form are buried in the upper layer of soft ground to form a drainage means. Expanded plastic plates 21 consisting of expanded styrol plates 15, etc., are stacked up on the drain means. The granular drain plates are continuously interposed on the boundary between the expanded plastic plates laminate layer end and the side banking to form connected bankings. Surface covering soil 20 is formed on the uppermost position of the plastic plates 21 to construct a pavement structure consisting of the plastic plates 21, sand 22, roadbed soil 23, and the surface layer 24, having a great shearing compressive strength. Since spring water in soft ground including land-slidable portion can be drained, the land sliding and subsidence can thus be prevented.
