Title: Thermal printer
Inventor: SEO KAORU
IPC: B41J2/365
Filed: 1991-07-02
Abstract: PURPOSE:To protect a thermal head against overheat and to enhance the picture quality by an arrangement wherein printing with next color is started after the thermal head is cooled to a temperature accounting for the temperature rise thereof predicted based on the print rate of previous color. CONSTITUTION:A print rate measuring section 10 calculates the print rate of yellow. Temperature rise of a thermal head 2 is then predicted based on thus calculated print rate thus calculating a print starting temperature TD. A temperature sensor 4 detects the temperature of the thermal head 2 after printing with yellow. A temperature monitoring section 5B monitors the temperature of the thermal head 2 based on the output from the temperature sensor 4 and when the thermal head 2 is cooled to the print starting temperature TD, a print start command is delivered to a head control section 1 and a mechanism control section 6.

IPC: G03G15/01
Filed: 1982-09-16
Abstract: PURPOSE:To convey a transfer material with good accuracy and to improve registration, by disposing electrostatic chargers for transfer and electrostatic chargers for sepn. to supports which support a transfer material between the spacing positions of the respective image carrying bodies which are made shorter than the length of the transfer material. CONSTITUTION:Respective photosensitive drums 1 are disposed at the space between each other shorter than the length in the moving direction of a transfer material P, and supports 21, 22, 23 which support the material P are formed to have smooth surfaces. While the material P fed to the drum 1a is attracted by the drum 1a, an image is transferred thereon with an electrostatic charger 5a for transfer, and the attraction force thereof is weakened by an electrostatic charger 12a for sepn., thus the transfer material is separated over the entire part in the transverse direction and since the resistance on the surfaces of the supports is small, the material is conveyed straightforward along the rotating direction of the drum 1a. The transfer material P across the two drums receives the conveying forces by the two drums. The transfer material is therefore conveyed, transferred and separated successively and is positively conveyed; therefore, the transfer material is obtd. with good registration.

Title: Ultrasonic flaw detector
Inventor: OONO MICHINORI
IPC: G01N29/04
Filed: 1979-12-14
Abstract: PURPOSE: To exclude the pseudo reflected wave and detect an accurate position of the defect, by oscillating the ultrasonic waves in the different two directions and detecting the defect which is equidistant from both directions.  
     CONSTITUTION: The pulse-type high-frequency signals oscillated from the flaw detector main body 1 are turned into the ultrasonic waves of different frequency bands via the probes 3 and 3, and these ultrasnoic waves propagate into the material A the flaws of which are detected. And if the material A has the defect B, each ultrasonic wave is reflected by the effect B. This reflected wave is received at the probes 3 and 3 each and transmitted to the frequency discriminators 4 and 4 after converted into the high-frequency signals. The discriminators 4 and 4 discriminate only the reflected waves of the ultrasonic waves which are oscillated from the corresponding probe, and the high-frequency signal is sent to the simultaneous measuring device 5. And the signal passes through the device 5 only when the signals are transmitted simultaneously from both discriminators 4 and 4 to be displayed at the display part 6 in the form of the defective reflected wave. In such way, the position of the defect can be detected accurately.
