Patent JP-S638923-A (JP)
Title: Optical position input device
Inventor: OUCHI JUNICHI
IPC: G06F3/042
Filed: 1986-06-30
Abstract: PURPOSE:To obtain a light signal with a constant light quantity and to prolong the life of a device by providing a driving means which drives a light emitting element with a constant current. CONSTITUTION:The potential difference generated across a resistance R1 with a driving current is supplied to the base of a transistor (TR) Q2 for negative feedback through a variable resistor VR and the impedance of the TR Q3 is adjusted. Consequently, the voltage obtained by dividing the voltage of a driving power source V through resistances R2 and R3 and the TR Q3 for negative feedback is applied to the base of a TR Q2 for control and the impedance of the control TR Q2 is adjusted. When a driving current flowing to one light emitting diode selected among L1-Ln is larger than a specific value, such a negative feedback circuit that the impedance of the control TR Q2 is larger is formed and the driving current becomes constant. Therefore, even if lead wires for flowing driving currents to the light emitting diodes L1-Ln and the pattern of a printed wiring board differ in resistance value, the light emitting diodes L1-Ln are driven with the constant currents and a light signal with a constant light quantity is outputted.

Title: Reflow soldering
Inventor: SAEKI KEIJI
IPC: H05K3/34
Filed: 1990-06-11
Abstract: PURPOSE:To make uniform the heating temperature of the whole printed board by a method wherein an electronic component is placed on the land of the board via a solder, this component is brought into contact to a liquid heated to a desired temperature to be subjected to heating, the solder is made to melt and the component is jointed to the land. CONSTITUTION:A printed board B is put in a state that a cream solder 5 is fed to a solder land 3 provided on a substrate 2 and an electronic component 4 is placed and is prepared for a soldering and is heated to 220 deg.C with a high- temperature liquid A. Accordingly, when the lower surface of the board B is brought into contact to the liquid A, the solder 5 is heated and melted by a heat conduction of the substrate 2 and leads of the component 4 are jointed to the land 3. As the solder 5 is made to melt via the heat conduction of the substrate 2 in such a way, an abrupt thermal shock is not applied to the component 4. As a result, its effect is hardly inflicted on the component 4. Moreover, even in the case there is a warpage in the substrate 2, the liquid A comes into closely contact to the substrate 2 because the heating unit is a liquid and the soldering is executed without generating an unevenness in heating according to a position.
