Title: Antiskid fixture for automobile tire
Inventor: KOTAKE KEISUKE
IPC: B60C27/12
Filed: 1986-12-10
Abstract: PURPOSE:To prevent the falling of an antiskid fixture and the cutting of a tightening band from occurring, by attaching a center locking member to a wheel, while stretching the hooking member attached to this locking member free of rotation, between antiskid fixtures, and making the tightening band so as to be stretched and engaged. CONSTITUTION:A center locking member 1 is attached to a tire wheel with bolt and nut. A hooking member 3 is rotatably fitted in the top of the erect part 1'' installed as stood erect concentrically with the center locking member 1, and a cap 4 is fitted in the outside. And, a hook band 5 consisting of rubber or the like is attached to an outer edge of this hooking member 3, and a hook 6 at the tip is engaged with an antiskid fixture S. With this constitution, even if there is produced slippage between the antiskid fixture and a tire with travel of a car, the hooking member 3 is relatively rotated to the tire together with the antiskid fixture. Therefore, the cutting of the stretching band and the falling of the antiskid fixture are preventable.

Title: Interface circuit using electromagnetic induction coupling
Inventor: KITATSUME MASAHIRO
IPC: H02J50/00
Filed: 1990-10-30
Abstract: PURPOSE:To always hold a period of a binarized output and a duty ratio constant irrespective of whether a magnetic flux is large or small by inputting a coil induced voltage whose level is shifted by a first capacitor to a binarizing circuit part having a threshold voltage of half of a power supply voltage and binarizing it. CONSTITUTION:An induction voltage induced in a coil 10 is subjected to voltage doubler half-wave rectification and a capacitor C2 is charged with a voltage Vcc of two folds of the induction voltage. In this case, since a threshold voltage of a binarizing circuit part 14 is Vcc/2 which becomes half of the power supply voltage Vcc, when an input voltage Vin from a (b) point exceeds, for instance, the threshold voltage Vcc/2, a binarized output Fout becomes an H level, and when the said input voltage is below the threshold Vcc/2, the binarized output Fout becomes an L level, and a binarized square wave output is generated. Accordingly, a zero crossing point in the induction voltage of the coil 10 becomes the same since the frequency is constant, even if amplitude is varied by a magnetic flux and the induction voltage becomes small. In such a way, a binarized output whose period and duty ratio become constant can be obtained irrespective of a variation of the magnetic flux for working on the coil.

Filed: 1995-11-10
Abstract: PROBLEM TO BE SOLVED: To effectively eliminate noise and prevent a risk of electric shock by forming an impedance circuit with a parallel resonance circuit which resonates with the frequency of a commercial power supply. SOLUTION: A grounding line 9 is connected to a grounding point 8 of an electronic apparatus 3 and an intermediate grounding point E of a parallel resonance circuit 5 and a parallel resonance circuit 6, a DC converting circuit 7 inputs a voltage of a commercial power supply 2 and converts it into a DC voltage required by the electronic apparatus 3 and an electronic apparatus 3 operates by receiving a DC power source from the DC converting circuit 7. Moreover, since the parallel circuit 5 and parallel. circuit 6 select capacity of capacitance and coil to realize resonance at the frequency of the AC power supply 2. Therefore, these parallel circuits have a high impedance for the commercial AC power supply 2 but a low impedance for the high-frequency noise superimposed.  As a result, high-frequency noise superimposed on the commercial power supply does not give any influence on the electronic apparatus and never gives any electric shock if a person touches on a part connecting the grounding line.
