Title: Temperature detecting circuit
Inventor: KARASAWA KUNIHIKO
IPC: G01K7/00
Filed: 1990-11-15
Abstract: PURPOSE:To linearize a change in output voltage with respect to temperature to improve accuracy in temperature detection by making constant current flow to a transistor and outputting differential voltage between a base and an emitter by an operational amplifier. CONSTITUTION:When reference voltage obtained by dividing voltage Vcc by resistors 6, 7 is assumed to be Vref, output voltage Vout1 of an operational amplifier 1 is Vref+kT/qX1n(mXn) where (q) is a charge amount, (k) is Boltzmann's constant, T is absolute temperature Kelvin, (m) is a ratio of a current value of a constant current source 5 to a current value of a constant current source, and (n) is a ratio in area of an NPN transistor 3 to an NPN transistor 2. Thus reversed saturated current and temperature characteristics of a current value I1 of the constant current source 4 are canceled so that the voltage Vout1 is completely proportional to the absolute temperature T. An amount in change of the voltage Vout1 with respect to temperature can be set as desired by changing a ratio (m) in current values of the constant current sources 4, 5 and a ratio (n) in area of the transistors 2, 3.

Abstract: PURPOSE:To enable a simple recording with a small and light-weight device, by a method wherein a thermal color-forming sheet is so set as to abut against an original at the thermal color-forming side thereof and the original and the thermal color-forming sheet are relatively scanned due to the intermittent emission of a flashing light source from the reverse side thereof and, thereby, the light is absorbed in the image area of the original to generate heat in the image area. CONSTITUTION:A sheet 4 is passed through a lower surface 9a of a presser means 9 so as to abut on an original 2 at the side of a thermal color-forming layer 4b, and a body 1 is traveled and made to scan in a direction of arrow A while the thermal color-forming sheet 4 is brought into close contact with the original 2. At this time, a control means 10 lights a light source 7 in a moment by every travel unit of the thermal color-forming sheet 4, which is slightly smaller in length than the irradiation range width of the flashing light source 7, to irradiate the original 2 from the reverse to the thermal color-forming side of the sheet 4. The light transmitted through the sheet 4 is absorbed in the image area of the original 2 to generate heat. Therefore, the area of the thermal color-forming layer 4b corresponding to the image area is subjected to heat to form color, and images are successively recorded on the sheet 4. In this manner, a sharp and high quality analog recording can be realized with a simple, small, and light-weight device.
