Title: Current comparator
Inventor: OKADA TAKAFUMI
IPC: H03M1/00
Filed: 1977-12-28
Abstract: PURPOSE: To provide a comparator which is advantageous for lower power and lower voltage driving by connecting respective switching elements to the respective reference current source of plural sets and subsequently turning ON the switching elements according to the levels of an input signal current source.  
     CONSTITUTION: When the current i s  increasing with time like A is supplied from an input signal current source 1, the current i s  is sucked into a constant current source 2a when i s <reference current i 1 , where the base potential of Tr2C is zero and Tr2C is OFF. When the current i s  exceeds i 1 , i s -i 1  flows into the source 3a via diode 2b, then the point of connection of the cathode of 2b and the source 3a is kept at zero potential and the base voltage of the Tr2C is kept at VD. As the current i s  increases, the base voltages are respectively kept at 4VD thru VD like Figs. B thru E and Trs2C thru 5e go ON. From the ON-OFF thereof, the magnitude of the current i s  may be known. Dividing of i s  to plural reference currents i 1  thru i 4  necessitates only several VD to obtain i 1  thru i 4 , enabling lower power and lower voltage driving to be achieved.

Abstract: PURPOSE:To prevent the lowering of visibility in a vehicular visual prism for refracting the beam of light incoming from the direction of an object to be visualized and making it go out in the direction of the eye point of a driver. CONSTITUTION:In a vehicular visual prism 10 having the incident plane 1a, the outgoing plane 2a and the bottom face 3a so as to refract the beam of light Ba entering from the direction of an object O to be visualized and to make it go out in the direction of the eye point Q of a driver, the inclination of the incident plane 1a to the horizontal plane is made thetaAa, and the angle of the base angle formed by the incident plane 1a and the bottom face 3a is made thetaCa. thetaCa is so set as to satisfy thetaCa=thetaD+thetaE, where thetaD is the angle of the beam of light. Ba, entering the incident plane 1a from the direction of the object O, to the horizontal plane, and thetaE is the angle of the beam of light Ba, entering at the angle thetaD and outgoing from the outgoing plane 2a after being transmitted through the visual prism, to the horizontal plane. The beam Ba outgoing from the outgoing plane 2a thereby becomes parallel with the bottom face 3a, so that the view of the driver is not intercepted by the bottom face 3a unnecessary for visibility.

Title: Non-contact identification system and data communication method
Inventor: FURUKAWA HIROHISA
IPC: G06K17/00
Filed: 1998-06-09
Abstract: PROBLEM TO BE SOLVED: To improve the safety of data at the time of radio transmission in a non-contact identification system. SOLUTION: A reader/writer 10A outputs an ASK modulation signal with a first modulation degree to the side of a data carrier 11A. The data carrier 11A detects the signal of the first modulation degree, provides reception data and inputs them to a communication logic circuit 24. A transmission signal from the data carrier is sent out by changing the load of a resonance circuit 20 with a second modulation degree shallower than this. By subtracting an ASK modulation output from a signal provided at a coil L1, the reader/writer 10A extracts a load fluctuation component on the side of the data carrier, detects that component and defines it as a reception signal. Thus, fully duplex communication is enabled and data contents are hardly detected by the third person.
