Title: Coplanar patch antenna
Inventor: PIITAA JIYOON GIBUSON
IPC: H01Q9/04
Filed: 1988-12-19
Abstract: PURPOSE: To obtain power feeding point resistance adjacent to the representative system impedance of 50Ω by providing a slot line formed on a ground plane for a means feeding an electric signal to open this slot line to a gap between a ground surface and a patch. CONSTITUTION: The electric signal is fed to an antenna by the slot line 5 formed as the gap at the ground plane 3 and opened to the gap 4 between the plane 3 and the patch 2 at a point A. Electric fields from rims on horizontal upper and lower sides of a slot line ring are mutually added along a normal line with respect to the center of the patch in terms of structure. On the other hand electric fields from two vertical rims passing through points A and B are mutually cancelled. Consequently an electromagnetic field radiated by feeding power to a port 6 is provided with an electric vector vertical to this plane. Thereby the power feeding point impedance of a serial slot line for feeding power is made comparatively approximate to the representative system impedance of 50Ω.

Abstract: PURPOSE: To prevent an occupant from feeling uncomfortable by predicting the vibration input to be transmitted from the unsprung at a rear wheel to a vehicle body to achieve the canceling control of the vibration of the rear wheel and the forward wheel, and changing the control gain of the forward wheel according to the pitching quantity of the low frequency components of the forward wheel to reduce the low frequency pitching. CONSTITUTION: Vertical acceleration of a vehicle body Ga -Gc , the strokes HFL, HFR, and the vehicle speed V are read to obtain the calculated acceleration GFL-GRR and pitch angular acceleration or right and left forward wheels θ''. Then, the speed ZFL, ZFR of the unsprung motion of the forward wheels are estimated to calculate the delay time τ and the correction value Δτ by the time when the rear wheels reach the road surface where the forward wheels pass, and these data are stored in the register. The speed of the unsprung motion of the rear wheels is obtained from the speed of the unspring motion before the time period of τ, and is integrated to calculate the displacement ZRL, ZRR of the unsprung. The predicted control force and the control force of the forward wheels are calculatd from the vibration input from the unsprung of the rear wheel based thereon, and the low frequency pitching is reduced by the control of the forward wheels and the predicted control of the rear wheels.

Title: Ringing choke converter
Inventor: SUGIHARA TOSHIMASA
IPC: H02M3/338
Filed: 1989-12-13
Abstract: PURPOSE:To prevent a transistor from being conducted earlier than resetting of a transformer by additionally providing a diode and a capacitor thereby suppressing base potential rise during OFF interval of a switching transistor without sacrifice of starting characteristic. CONSTITUTION:A diode D3 and a capacitor C3 are additionally provided. Current flowing in from a resistor R1 is shunted to the capacitor C1 side and the capacitor C3 side thus retarding voltage rise of the capacitor C1 correspondingly. Potential rise at the joint of R1 and D3 is also low because the capacitor C3 is charged reversely with the current from the resistor R1 being fed by the voltage of L3 upon turn OFF of a transistor Q1. Since the transistor Q1 is sustained in perfect OFF state for a longer time, the transistor Q1 can be conducted at a time point when the voltages of all windings go to zero after perfect reset of the transformer T.
