Title: Tracking ball
Inventor: YOSHIKAWA JUNICHI
IPC: G06F3/0354
Filed: 1994-07-04
Abstract: PURPOSE:To easily integrate the track ball into the supporter of slender struc ture like pen type by reducing the area of projection to the moving plane of a ball by using a specified photosensor for detecting the rotation of the ball. CONSTITUTION:Light emitted from a light source 7 is reflected by a ball 8 and made incident to photosensors 1-4. Four photosensors 1-4 detect the change of reflected light from the freely rotatable ball 8 separately painted in two colors with different values of reflectance. Namely, the rotation of the ball 8 is detected corresponding to a pattern change on the photosensor side surface of the ball 8 with the rotation, and the X and Y direction moving amounts of the ball 8 are detected by changes in the outputs of four photosensors 1-4. Thus, since four photosensors 1-4 are used for detecting the rotation of the ball 8, any roller and rotary encoder are not required like the conventional case, and the area of projection to the moving plane of the ball 8 can be reduced.

Abstract: PURPOSE:To suppress a detection error due to the influence of ambient temperature by providing a feedback circuit which feeds the output of a bridge circuit back to the bridge circuit through a compensating resistance. CONSTITUTION:The resistance value of the temperature measuring resistance 3 at one branch of the bridge circuit 8 is R0 when its temperature is 0 deg.C, and the circuit 8 enters a balanced state to generate an output voltage of 0V at an output terminal 7, but if the temperature rises or falls, the temperature measuring resistance 3 increases or decreases in resistance value and the circuit 8 becomes unbalanced. If this enters the balanced state, the output voltage EOB corresponding to variation in the resistance value of the temperature measuring resistance 3 is developed at the output terminal 7, but when a part of the output EOB is added to the voltage Er of the reference voltage source 6 of the circuit 8 by an adding circuit 12, the voltage of the reference voltage source 6 is elevated equivalently in proportion to the temperature variation and the output EOB of the circiut 8 varies with temperature according to a hyperbolic curve, which is approximated to the temperature characteristics of the thermocouple by selecting the value of each resistance properly.

Title: Recording paper conveying device
Inventor: SUE TAKATSUGU
IPC: G03B27/58
Filed: 1982-08-31
Abstract: PURPOSE:To make it possible to obtain sufficient drive torque with the use of a small capacity pulse motor, by driving the pulse motor with two phase energization after the pulse motor is driven with one or two phase energization by first several hundred pulses, upon the reverse rotation of carrier rollers by the pulse motor under cutting instructions. CONSTITUTION:When a pulley 43 is rotated counterclockwise by a motor 41, a roller 29 rotates counterclockwise to progressively feed a recording paper but a gear 47 does not rotate. Simultaneously, since a gear 61 rotates counterclockwise, a feed roller 35 rotates clockwise to feed the paper. Further, although a gear 67 rotate clockwise, but it idles between itself and a shaft 62 due to an one-way clutch 66 disposed therebetween. Next, when the motor 41 reversely rotates, the roller 29 also reversely rotates to stretch the recording paper and as well to release a cutter cam follower 58 from a cam 49, so that a bracket 57 is rotated until a projection 59 abuts against a stopper 60, and therefore, the recording paper is cut by a movable cutter blade 34. At thist time, the drive of the motor with one or two phase energization offers a feed speed half as high as that with two phase energization, but produces a large torque, thereby the drive may be made with a small capacity motor.
