Title: Led driver circuit
Inventor: MIZOGUCHI TADASHI
IPC: B41J2/44
Filed: 1987-12-17
Abstract: PURPOSE:To always fix the quantity of light emission of an LED in spite of a temperature variation and a change with the passage of time by changing a current value to be supplied to the LED in accordance with the quantity of electricity proportional to a difference between the quantity of electricity proportional to the quantity of light emission of the LED and a reference value of the light emission quantity. CONSTITUTION:When temperature rises higher than a set value for instance, the output of an operational amplifier 5 is increased due to the reduction of the quantity of light emission of the LED 1 and a decoder 7 selects a resistor 18. Thereby, the current value I supplied to the LED 1 is increased and the quantity of light emission is increased. When the temperature rises furthermore, a resistor 19 is selected and the quantity of light emission is increased, and when the temperature falls, a resistor 16 is selected and the quantity of light emission is reduced. Consequently, the fixed quantity of light emission can be always obtained from the LED 1 in spite of a temperature variation and a change with the passage of time.

Title: Optical receiver
Inventor: AGAWA KEIGO
IPC: H04B10/564
Filed: 1988-12-20
Abstract: PURPOSE:To obtain an output signal corresponding linearly to an input signal by providing a capacitor to cut off the DC component of a light signal and a coil to ground the DC component of the light signal. CONSTITUTION:The light signal is detected by a photodiode PD, and is outputted to an amplifier AP through a capacitor C. In the case where the light signal whose DC component is large is detected by the diode PD, the DC component is cut off by the capacitor C, and only a signal component as essential information is inputted to the amplifier AP, and is amplified, and is supplied to prescribed processing. The cut off DC component of the light signal is grounded through the coil L. Thus, since the DC component of the input signal is cut off by the capacitor C, the DC bias point of the amplifier AP, that is, the reference voltage of the amplification of the input signal comes not to vary. Accordingly, the output signal whose input/output characteristic corresponds linearly to the input signal can be obtained.

Filed: 1991-11-11
Abstract: PURPOSE:To make large resisting force act in response to a stroke of the rod of a friction damper when it exceeds a fixed distance. CONSTITUTION:A friction member 15 is fitted to a cylinder 14 capable of sliding, and the friction member 15 is connected to a rod 16. A compression spring 17 is wound to the small diameter part 16a at the top end of the rod 16, and held by a spring sheet 19 in a state wherein it is compressed with a specified set load. A compression spring 22 is wound to the rod 16, and held by a spring sheet 24 supported by a snap ring 23 in a state wherein it is compressed by the specified set load. Annular projection parts 28, 29 are respectively formed on the internal circumferential surface near to the both end parts of the cylinder 14. With these means, this friction damper normally produces relatively small damping force by the friction force of the friction member 15. When the rod 16 performs a stroke that exceeds a fixed distance, the spring sheet 19 or 24 abuts on the projection part 28 or 29, and the compression spring 17 or 22 is compressed, thereby large resisting force acts for the expansion of the rod 16 by its elastic force.
