Title: Thermal printer and method of controlling printing
Inventor: UENO ASAO
IPC: B41J2/365
Filed: 2000-05-10
Abstract: PROBLEM TO BE SOLVED: To obtain a temperature which is detected as an ambient temperature instead of a temperature of a paper so as to be near the actual temperature in order to achieve stable printing quality. SOLUTION: There is disclosed a method of controlling printing for a thermal printer wherein the ambient temperature is detected by a temperature sensor provided in a body case and energy to be applied to a heating resistor mounted on the thermal head is controlled by referencing the ambient temperature and the temperature of the thermal head at a time when the printing is started. The sensor for detecting the ambient temperature is provided in the body case of the thermal printer.

Title: Semiconductor device and manufacturing method therefor
Inventor: OKADA TETSUYA
IPC: H01L29/73
Filed: 2000-05-10
Abstract: PROBLEM TO BE SOLVED: To solve a problem that electric field is concentrated on a depletion layer at the periphery of a guard ring and there is a limit in high breakdown voltage since a problem that the PN junction of a base area and a collector area makes almost a right angle, that the electric field is concentrated on the depletion layer at the periphery of the base area and a system breaks down, and that the depletion layer at the periphery of the guard ring for preventing the concentration still concentrates the electric field. SOLUTION: A recessed part is formed in an N-layer semiconductor substrate 2 and the base area 8 of a recessed type is formed along the recessed part. Since the side inclines, the angle of PN junction becomes large and a curvature at the periphery of the base area can be relieved. Since the recessed part is also installed in a guard ring 9 in an innermost periphery, the curvature of the guard ring can be relieved. Then, the base area having a leg can be formed without using a mask process. Thus, breakdown voltage is made high and the process can be simplified.
