IPC: B41J33/14
Filed: 1987-02-26
Abstract: PURPOSE:To enable a ribbon take-up quantity to be reduced, by decelerating a carrier movement at the time of an overrun after printing. CONSTITUTION:When an input through a character key 2 is given, a carrier is moved from a position E under acceleration by P1 pulses in the direction opposite to a printing direction. When the carrier reaches a position F under acceleration, it is moved by P2 pulses, and is stopped. Next, the carrier is moved from a position K to a position J by P3 pulses, with an acceleration from A PPS to C PPS. After the carrier reaches the position J, the section from the position J to a position H corresponding to P4 pulses is a section for printing one character, and printing is conducted by a thermal head 10 in this section. Thereafter, a CPU judges that printing of the character is finished, and an overrun to a position G is performed at a velocity of C PPS by P5 pulses. At the position G, a motor 7 is driven to start a thermal head turning-up operation. Simultaneously, deceleration of the carrier movement is started at the position G, and the CPU controls the deceleration from C PPS to A PPS, while the carrier is moved to a position D by pulses P6. The carrier is stopped at the position D. In this case, the ribbon take-up quantity after printing is reduced by an amount corresponding to M-L pulses, as compared with that in a conventional system.

Title: Creep-damage detecting method for high-temperature structure member
Inventor: FUJIYAMA KAZUNARI
IPC: G01N3/60
Filed: 1990-02-27
Abstract: PURPOSE:To improve the reliability in detection of damages by performing transfer of replica and clear image processing, and plotting the diameter of crystal grains deposited on metal texture or the average value of the ratio of the long diameter/short diameter of the deposited material as a master curve. CONSTITUTION:The detecting part of an effective part 1 of each turbine bucket 3 is polished and corroded with organic material. Thereafter a film (h) is stuck, and the metal texture is transferred. The transferred image is treated with vacuum-vapor deposition using amorphous carbon. The image is dried and solidified. Thus, the image with the replica is formed. Then, the transferred image with the replica is observed with a transmission type electron microscope (b). The image is photographed. The observed image is inputted into an image processing device 5, and binary coding is performed (c). Noises such as the deposited material of carbide and the like are removed. Aggregation and coarse enlargement are performed, and only gummer prime (i) having the directivity is made to be the image. In the gummer prime which is undergone image processing, the ratio between the long diameter and the short diameter is automatically computed. The average value is operated and made to be the data. The obtained data are plotted as a creep damage characteristic curve 7 that marks a master curve 6 prepared beforehand. Thus the creep damage value is obtained.

Title: Arc welding machine
Inventor: KASHIMA TAKAYUKI
IPC: B23K9/06
Filed: 1983-03-18
Abstract: PURPOSE:To perform satisfactory arc welding with low noise without arc interruption by providing a time delay circuit for shaping current waveform between a peak-base current changeover circuit and an error amplifier. CONSTITUTION:A time delay circuit 18 for shaping current waveform is inserted between a peak-base changeover circuit 12 which changes over selectively the output from a peak current setter 10 and the output from a base current setter 11 and an error amplifier 14. The response is made slower by a delay circuit 18 than the delay factor of a feedback system by a current detector 7 and therefore the overshoot and undershoot generated in the stage of changing over the peak current and the base current are suppressed and an arc interruption is prevented. Since the current waveform at the rise and fall is suppressed, the arc noise by the pulse current is decreased.
