Title: Dot printer
Inventor: IWAKI TAKAHISA
IPC: B41J2/485
Filed: 1995-04-14
Abstract: PURPOSE: To improve print quality by a dot printer wherein a contour highlighting latticed data is created based on a printing data from the outside by a latticed data creating means and a print head is driven based on the contour highlighting latticed data by moving the print head in the horizontal scanning direction so as to output dots. CONSTITUTION: In printing, a CPU 11 creates a contour highlighting latticed data based on a printing data from a host computer 17. In the printing data, when the number of black dots which continue in the horizontal direction is of odd number, they are converted into white dots at every other dot from a next dot in the horizontal scanning direction. Thus, a data as a final data on the contour is left as black dots as it is. On the other hand, when the number of the continuing black dots is of even number, they are converted into white dots at every other dot from a next dot in the horizontal scanning direction. A data on the contour as final dots is left as black dots as it is. Thus, the contour highlighting latticed data wherein all data on the contour arranged in the vertical scanning direction become black dots is created.

Title: Tire puncture detecting device
Inventor: FUKUMOTO YOZO
IPC: B60C23/06
Filed: 1985-04-25
Abstract: PURPOSE:To precisely detect puncture, by deciding the puncture when a ratio of a continuation time of a signal greater than a fundamental level of a tire load signal to a signal greater than a tire inner pressure abnormal level is different from a predetermined reference value. CONSTITUTION:A load signal from a load detector 1 such as a load cell and a pressure sensitive switch for detecting a load to a left or right pneumatic tire is input to first and second trigger circuits 2 and 3. The load signal is divided into a signal greater than a tire load detection level L1 and a signal greater than a tire inner pressure abnormal level L2. Continuation times of both the signals are measured by timers 4 and 5. The measured continuation times t1 and t2 input to an operating section 6 to operate a ratio between the measured times t1 and t2. Then, the ratio (t2/t1) is compared with a predetermined reference value S by a comparator 7. When (t2/t1)<S, a tire inner pressure abnormality signal is input from the comparator 7 to an indicating section 8 to indicate puncture of the tire.
