Title: Light source drive circuit
Inventor: WATANABE HIROYUKI
IPC: G02F1/1335
Filed: 1998-04-16
Abstract: PROBLEM TO BE SOLVED: To provide a light source drive circuit, wherein with dispersion of drive current for an LED(light-emitting diode) suppressed, such brightness as a fluorescent lamp light source is assured at least around normal temperature which is used frequently. SOLUTION: This LED drive circuit, in which LED 1-LED 4 are connected to the collectors of four transistor TR2-TR5 respectively, comprising constant current circuits with a base directly connected, an emitter follower, and a resistive potential dividing circuit. The resistive potential-dividing circuit comprises resistors R1, R2, R3, and a thermistor TH1. By setting each of constants so that the negative temperature characteristics of the thermistor TH1 is more dominant than the positive temperature characteristics of a base-emitter voltage VBE1+VBE2, an LED current gradually decreases as the temperature rises in a temperature zone to a normal temperature (25 deg.C) or above, while the LED current is almost constant in the temperature zone at normal and low temperature zones.

Title: Apparatus of pointing device
Inventor: HOSOKAWA HIROSHI
IPC: G01B11/00
Filed: 1990-04-24
Abstract: PURPOSE:To make it possible to specify space coordinates and to make it possible to specify the coordinates in arbitrary directions by detecting laser light beams which are emitted from a pointing device in the three or more directions which intersected at right angles. CONSTITUTION:The coordinates specified by a pointing device 101 are made to be (X, Y and Z). The coordinates of elements 108, 110 and 109 which have detected laser light beams 103 - 105 emitted from the device 101 are made to be (a1, b1 and c1), (a2, b2 and c2) and (a3, b3 and c3), respectively. Then, the vectors of the laser light beams 103 - 105 are expressed by the expressions I, respectively. Since these vectors are intersected at right angles, the inner products of the vectors become 0. Therefore, the expression II are obtained. In these expressions a1 - a3, b1 - b3 and c1 - c3 are constants. Therefore, the coordinates (X, Y and Z) are obtained by the three simultaneous equations of three variables. The device 101 is used in this way, and the space coordinates of the device 101 are computed based on the three coordinates which are detected by the laser photodetectors. Thus, the space coordinates specified by the device 101 in the arbitrary directions can be detected.
