IPC: B41J2/01
Filed: 1998-04-08
Abstract: PROBLEM TO BE SOLVED: To provide a printing device which performs the optimal time-sharing drive of a thermal head in accordance with the type and the electric power of a power supply. SOLUTION: In the printing device 10, an I/F 12 stores printing data to be entered from a host computer 23 in memory, and a memory unit transfers the printing data to a TH control part. The TH control part prints the data while driving the number (the number of simultaneous power applications) assigned by an MPU 11 of thermal elements of a thermal head (TH) 18 in a time-sharing mode. The output of a cell 21 is converted to a voltage Vh, by a DC/DC converter 22, which is, in turn, entered to the thermal head (TH) 18 and a power measurement part 17. The power measurement part 17 applies the voltage Vh to a simulated load resistance prior to printing to check on a voltage drop V1.  The MPU 11 calculates a currently suppliable power under this voltage drop condition and controls the thermal head (TH) 18 in such a way that when the calculation shows a high power W1, the number of simultaneous power applications is a maximum 12 and when the calculation shows a slightly lower power W2, the number is 10 and further, the calculation shows a critical power W3 for use, the number is 8.

IPC: A62B1/02
Filed: 1999-04-05
Abstract: PROBLEM TO BE SOLVED: To provide an emergency carrier usable for emergency purposes such as rescue work for sick and wounded person, different from ordinary purposes. SOLUTION: A plurality of grooves 21a of almost V-shaped cross section are formed in a position corresponding to a chamfered part 21a and then curved inward. The density of remaining wall thickness after forming a plurality of grooves 21a of almost V-shaped cross section therefore becomes high when plastically deformed, and excessive force is not applied to a plurality of grooves 21a of almost V-shaped cross section when bent, so that internal stress is hardly generated. Even if a large external force is partially applied to the chamfered part 21A, since the density of remaining wall thickness after forming a plurality of grooves 21a of almost V-shaped cross section is high and the thickness can be thickened or thinned in a right-angled direction to the lengthwise direction, the chamfered part 21A can change without being broken by stress and is prevented from being broken by stress.
