Title: Three-dimensional accurate locating system for observation point or satellite through relative measurement
Inventor: KAWAMATA KENICHI
IPC: G01S3/02
Filed: 1992-02-08
Abstract: PURPOSE:To measure three-dimensional positions at high accuracy kinematically by dividing a specific sky area above observation points into plane layers each of which is parallel to a plane passing the observation points, and calculating the radio refractive index of each parallel plane layer. CONSTITUTION:The time required for an electric wave to propagate between a satellite and an observation point is measured and the vertical distance between the satellite and the observation point is measured. The cosine of the angle at which the electric wave reflected from the satellite at that time impinges on the boundary between the layer through which radio waves rectilinearly propagate and the ionosphere is calculated at desired accuracy. Such a set of data are synchronized with orbit information transmitted via geostationary satellites and for each satellite 1000 sets of the region going up to 1000 km from each observation point are calculated to correspond to the observation points. Simultaneous linear equations of 100 degrees are thus provided at each satellite and solved to calculate at desired accuracy the radio refractive index of each of parallel plane layers near which radio waves connecting the satellites to the observation points are transmitted. The position of each observation point relative to the satellites is thus determined. Since the position of each satellite at a given time is determined, the three-dimensional position of each observation point is determined.

IPC: H02H3/16
Filed: 1992-03-26
Abstract: PURPOSE:To detect occurrence of ground fault on the neutral line side or a converter located at isolated neutral end by comparing the output from a neutral line current detector with the output from a current detector on the neutral line side of the converter located at the isolated neutral end, in a bipolar DC transmission system having neutral line grounded at one end while isolated at the other end.

IPC: G06F17/21
Filed: 1994-03-14
Abstract: PURPOSE:To designate the input range of inputted character strings with ruled lines and to output data while excluding any specified ruled lines when outputting the data. CONSTITUTION:When character data are inputted, inside a document memory 22-1, it is discriminated whether a ruled line code showing a virtual line at a present line is stored or not. When the ruled line code of the virtual line is stored, an inputted character code is written inside a range up to the ruled line position in the document memory 22-1 designated by the ruled line code of the virtual line. When document printing is designated, the data of a printing target are read from the document memory 22-1, and it is investigated whether those data are ruled line data or not. When they are the ruled line data, it is judged whether these ruled line data are virtual lines or not based on attribute data contained in these ruled line and when they are normal ruled line data, the ruled line data are transferred to a printer control part 20 and printed out of a printer 16 but when they are the ruled line data of the virtual lines, those ruled line data are not transferred to the printer control part 20 but the printing is inhibited.

IPC: B41J2/345
Filed: 1987-03-24
Abstract: PURPOSE:To prevent shortcircuit between electrodes through abraded powder by arranging two rows of electrodes in parallel and switching the first row electrode and second row electrode properly between a common electrode or a recording electrode according to the printing direction. CONSTITUTION:When a recording head is moved in the direction of an arrow A, an electrode 1 in first row is employed as a common electrode while an electrode 2 in second low is employed as a recording electrode and potential is applied selectively onto electrodes 2a-2c according to print patterns so as to supply power. When a recording paper is fed by single line after printing of single line, then the recording head is moved in reverse direction from the arrow A so as to make a print, the electrode 2 in second row is employed as a common electrode while the electrode in first row is employed as a recording electrode, then potential is applied to supply power. At this time, abrasion powder 10 adheres to the electrode 1 in first line. But abraded powder 9 adhered to the electrode 2 when printing is made in the direction of an arrow A is scratched off through the friction against a sheet member 6. When printing is performed again in the direction of an arrow A, abraded powder 9 adheres to the electrode 2 but abraded powder 10 adhered to the electrode 1 is scratched off. Consequently, shortcircuit between electrodes 1 and 2 through abraded powder can be prevented.
