Title: Hot water storing electric container
Inventor: SUGIZAKI SHUNEI
IPC: A47J27/21
Filed: 1997-03-31
Abstract: PROBLEM TO BE SOLVED: To prevent abnormal pressure rise in an inner container, and securely close a steam passage when a container main body is fallen. SOLUTION: A pressure space 103 is formed between an upper surface of a valve body 93 and a lower surface of a cover body. As adhesion surface 101 of a valve body 93 and a protruded part 102 gets into an adhesion condition, pressure in an inner container acts on an upper surface of the valve body 93 as well as on a lower surface. The valve body 93 speedily gets off the adhesion surface 101 of the protruded part 102, so abnormal pressure rise in the inner container is avoided. As a container main body is fallen, the upper surface of the valve body 93 tightly gets in contact with the adhesion surface 101. A lower opening of a steam passage is thus completely closed, thereby leak of hot water from the steam passage to the external can surely be prevented.

Abstract: PURPOSE:To offset and correct the inclination of a recorded picture in spiral scanning, by constituting a light sensitive body drum so that it can be moved in the reverse direction with respect to the secondary scanning of an exposure unit, and moving the drum by the same distance as the moving distance of the exposure unit in the axial direction. CONSTITUTION:A slant angle theta of an electrostatic latent image which is exposed on the surface of the light sensitive body drum 1 by the spiral scanning is estimated in advance. For example, the drum 1 can be slowly moved in the reverse direction Y' with respect to the secondary scanning in response to the amount of movement L of the exposure unit per one rotation of the drum 1. In this way, an axial direction moving mechanism is provided. At the time of exposure, the drum 1 is rotated at a constant speed, the exposure unit is moved at an equal speed, and the exposure is performed by the spiral scanning. Then the development of the drum 1 is performed. Thereafter, the drum 1 is slowly moved by a distance L in the reverse direction with respect to the secondary scanning during the one rotation of the drum by the actions of a cam 35, pin 36, and the like, and the transfer is performed. The inclination of the spiral angle theta of the transferred picture is offset and the picture becomes straight.
