Title: Reflection type photosensor
Inventor: SUEHIRO YOSHINOBU
IPC: G01S17/02
Filed: 1988-03-23
Abstract: PURPOSE:To effectively radiate light emitted from a light emitting element on a photodetector, by radiating light emitting from a light emitting element by a recessed reflecting surface provided on a light emitting section and by radiating it on a photodetector by a recessed reflecting surface provided on a light receiving section. CONSTITUTION:A recessed reflecting surface 6a is formed in a rotating parabolic shape and a light emitting element 1 is arranged so that the light emitting side is opposite to a focus of the recessed reflecting surface 6a. Therefore, almost all the light emitted from the light emitting element 1 is reflected by the recessed reflecting surface 6a and radiated on a detected object 15 in parallel to the central axis of the recessed reflecting surface 6a. Since the photodetector 2 is arranged so that the light receiving surface is opposite to the focus of the recessed reflecting surface 6b, parallel light reflected by the detected object 15 is reflected again by the recessed reflecting surface 6b of the light receiving section 12 and then converged to the photodetector 2. In this way, light emitted from the light emitting element 1 is converged effectively to the photodetector 2 with approximately no loss.

Title: Radio ic card
Inventor: SATO YASUHIRO
IPC: G06K19/07
Filed: 1993-03-26
Abstract: PURPOSE:To improve reception sensitivity, transmission speed and service life of a battery by changing the bias current value of a bias current circuit and/or the resistance value of a load resistor corresponding to classification between standby time and communication time. CONSTITUTION:A signal inputted from an antenna 11 is passed through a matching circuit and detected by a detection diode 13. At such a time, a voltage at both ends of the diode 13 is drawn out through a terminating resistor 14 as a detection output 17. The bias current to the diode 13 is passed from a bias source 18 through a current limit resistor 19 and passed through a high impedance line 20 so as to eliminate the influence of a high frequency. At the time of communication, the resistance of the terminating resistor 14 is set small by a signal 16 from a control circuit 15 and when the detection output 17 is oppositely turned to zero, namely, at the time of standby, the resistance value of the terminating resistor 14 is set large by the signal 16 from the control circuit 15. Thus, the sensitivity at the time of standby is prevented from being made low so much. Therefore, even when the bias current is small, the sensitivity of demodulation is comparatively improved.
