Title: Cascade control system
Inventor: INOUE YOSHINORI
IPC: G05B7/02
Filed: 1983-04-27
Abstract: PURPOSE:To perform mode switching in an easy and safe way by controlling a follower controller based on the control deviation between the control output of a main controller and the mean control output value obtained from follower controllers. CONSTITUTION:A follower control loop contains follower controllers 101-10n and intermediate control processes 51-5n. While a main control loop consists of a main controller 3 which obtains the coincidence between the sum of the intermediate control process quantity obtained from the final process 4 and the set value of a setting device 1. The cascade control where the control output given from the controller 3 is defined as the set value of controllers 101-10n is switched to the constant value control using setting devices 61-6n by means of switches 81-8n. The output of the controller 3 is stored in analog memories 71-7n. Then adders 111-11n, a deviation operator 12 and an operator 13 which calculates the mean value of follower controller outputs are added to the constant value control side. Thus the constant value control is smoothly switched to the cascade control.

Title: Rice cooking jar
Inventor: FUKUSHIMA TADASHI
IPC: A47J27/00
Filed: 1993-03-31
Abstract: PURPOSE:To improve efficiency of heating and heat retention and to make a rice cooking jar economical and suitable for mass production by the use of common parts, by constituting the heat insulation wall made of resin molded material in the shape of tube type wall extending in top and bottom directions. CONSTITUTION:A heat insulation resin wall 16 made of non-heat conductive material covers the inside of the outer case. As the result, as the outward transmission of heat is interrupted on the way, deteriorating effect by heat on the part material of the outer case, etc., is eliminated and useless heat radiation is also prevented. A tube- type wall 16b of the coil stand 13 side is extended and formed high. Structurally, the tube-type walls 16a and 16b stand side by side in the horizontal sectional view with their ends dislocated with each other. Further, the walls are structured in such a manner that their ends come parallelly in and out on the same horizontal face. As the upper frame 11 and the coil stand 13 in the same structure are used for various sizes of rice cooking jars, use of common parts for various sizes becomes possible, reducing the number of parts items and making them suitable for mass production. Further, as the tube-type walls 16a and 16b overlap in the small size jars, they work in the complementary manner and maintain high heat insulation and heat retention capacity even though an allowed difference in the measurement of a distance is set roughly.

Abstract: PURPOSE: To attach an electrode without adversely affecting the other already attached electrode when the electrode is to be attached to an electrically conductive rib of a unit electrolysis cell, by spot-welding the electrode with both the welding electrodes arranged from the same direction to the first-mentioned electrorde.  
     CONSTITUTION: To attach the electrode 2 to the electrically conductive rib 5 of the unit electrolytic cell 1, both the welding electrodes 3, 4 are arranged on the electrode 2 as shown.
