Title: Distance calculation device and position calculation device
Inventor: NAKAI SHINJI
IPC: G01C21/00
Filed: 1998-09-14
Abstract: PROBLEM TO BE SOLVED: To reduce a burden in terms of a calculation without increasing a measuring error by a method wherein the length of one minute of a latitude difference on the meridian at a latitude in a certain point in a desired geodesic system and the length of one minute of a longitude difference on a parallel circle at a longitude are calculated in a digital region. SOLUTION: A direction sensor 1 detects the direction in the advance direction of a vehicle at an interval of a unit time so as to be output. A speed sensor 2 detects the speed of the vehicle at an interval of the unit time so as to be output. A microcomputer 3 calculates the present position of the vehicle at a cycle of the unit time on the basis of the output of the direction sensor 1 and on the basis of the output of the speed sensor 2, and a map image provided with an own-vehicle-position mark is plotted in a video RAM 4 by using map data. The image in the video RAM 4 is read out by a display controller so as to be displayed on a screen. When a length is calculated in a digital region, an approximate curve which is polynominal- approximates by the method of least squares is used.  As a result, the computation of a trigonometric function is not required, a burden in terms of a calculation is reduced, and specifications which are required from hardware used to execute a processing operation are relaxed.

Title: Current detecting device
Inventor: HARADA KOSUKE
IPC: G01R19/00
Filed: 1988-10-19
Abstract: PURPOSE:To decrease the number of component parts, and to contrive the miniaturization and the conversion to bipolarity by supplying positive and negative voltages to a secondary winding of a current transformer by a single voltage source through a single field effect transistor. CONSTITUTION:When a field effect transistor FET1 is in an ON-state, a current flows to a primary winding N3 of a transformer T2 from a voltage source +E and energy is stored in the transformer T2. Subsequently, when it is inverted to an OFF-state by a resonance of a saturation inductance of a magnetic core I and a gate - source capacity, a negative voltage obtained by an inversion of a positive voltage generated in a secondary winding N4 by an action of a diode D is supplied to a secondary winding N2 of a transformer T1 by a primary winding N3. When the magnetic core I of the transformer T1 reaches the negative saturation by its negative voltage, the FET1 is converted to an ON-state again and a repeated alternate inversion is executed.

Title: Garbage treatment device
Inventor: SUGIURA SHIGETA
IPC: B65F1/10
Filed: 1995-10-09
Abstract: PROBLEM TO BE SOLVED: To improve garbage agitation efficiency by providing blades in such a way that angular intervals in the circumferential direction of a rotary shaft between respective blades become irregular. SOLUTION: Inclination angles of blades 26a-26d on a rotary shaft 25 to a horizontal plane in a tank 17 are set to be gradually larger as it goes from the first blade 26a at the lowest end to the forth blade at the uppermost end. As viscosity of garbage in the treatment tank 17 becomes higher, spirally linked garbage are pushed up by the respective blades 26a-26d, and the blades 26a-26d get in contact with it at irregular intervals in garbage extended directions. Push-up force by the blades 26a-26d thus operates to plural positions in the garbage at irregular intervals in its extension directions, so the spirally linked garbage are broken. It then drops to a lower part of the treatment tank 17.

Abstract: PURPOSE:To make the construction work of stay anchor easier as well as to obtain strong bearing capacity by a method in which resistor plates are driven into the ground, an upper pulling plate is pressed on the resistor plate side and then moved toward the pulling direction to apply impact to a guide plate, and a stable plate is inserted and coupled with the upper pulling bar. CONSTITUTION:A trench is excavated in the ground, a resistor plate B is driven, and an upper pulling plate 29 is pressed on the resistor plate 20 side by soil pressure to make it closely contact with a reinforcing plate 21 to allow it to reach the bottom of the trench in the closed state. The plate 29 is then moved to the pulling direction, and a guide plate 28 is bent into a fixed angle with a connecting plate 25 to give impact to the plate 28. Whereupon, the plate 28 is exposed to the bottom face of the trench and comes into contact with the tail end of the resistor plate 20. A stable plate 37 is driven along the plate 28, and an upper pulling bar 35 is fitted into a connecting ring 31 and combined. The resistor plate and the stable plate can thus completely resist the soil pressures by their flat faces, enabling strong bearing capacity to exhibit.
