Title: Construction of outer cylindrical shell of heater
IPC: A47J36/26
Filed: 1992-03-27
Abstract: PURPOSE:To restrain a temperature rise at the periphery of a cylindrical shell main body consisting of a cylindrical thin metal plate by heat distribution through the metal cylindrical shell main body, increase the thermal efficiency for reducing fuel consumption, and improve the heat-insulating property by a method wherein heat- insulating material is applied on at least inner surface of the cylindrical shell. CONSTITUTION:During heating, a burner 10 is ignited to directly heat a can main body 6c from the bottom by a flame spouted from the burner 10. As the lower end of a partition plate 9 is lower than the bottom of the can main body 6c, hot-air produced by the flame of the burner 10 rises through only an inner space which faces the outer face of the can main body 6c, so that a canned food 6 can be efficiently heated and the heat amount which passes along an outer cylindrical shell 2 is reduce. During heating, the partition plate 9 directly contacts with combustion gas and is heated to high temperatures and the heat is transferred from the partition plate 9 to a heat-insulating material 21 through the joint part on the periphery side. Since the heat-insulating material 21 has a heat-insulating and heat-storing properties, heat is gradually transferred to an outer cylindrical shell main body 22 at a reduced heat transfer rate.

Title: Head position control circuit of magnetic recording and reproducing device
Inventor: ITOU TAKAYASU
IPC: G11B5/588
Filed: 1984-04-11
Abstract: PURPOSE:To attain accurate tracking and also to increase the level of a reproduced output signal by comparing a sample-and-hold value of the same rotary head different from the 2-rotating scanning period and applying tracking control so as to attain accurate tracking. CONSTITUTION:When the 1st displacing direction deciding circuit 37 decides that the step displacing direction of this time is reversed from that of the preceding time, a discrimination circuit 39 decides the 1st phase correction signal to an impression signal generating circuit 7. When the 1st displacing direction deciding circuit 37 decides that the step displacing direction of this time is identical to that of the preceding time conversely, the discrimination circuit 39 outputs the 2nd phase correction signal to the impression signal generating circuit 7 in place of the 1st phase correction signal. Thus, since the phase difference of the same rotary head different from two-rotating scanning periods in the recording track width direction is 2.DELTAl or 0, where DELTAl is the displacement of one step correcting the phase of the head position, the comparison of the level is attained easily more than the case that the phase difference of the same rotary head different by one-rotating scanning period is compared.
