Title: Tableware washer
Inventor: OMACHI MASANORI
IPC: A47L15/46
Filed: 1999-04-16
Abstract: PROBLEM TO BE SOLVED: To accurately display the remaining period of washing even when the washing compartment of a tableware washer has remaining heat after continuous repeated operations. SOLUTION: At the start of the washing operation, a water temperature T0 is measured (S41, S44); after one minute passes, a water temperature T1 is measured (S47, S48); after two minutes pass, a water temperature T2 is measured (S49, S50); then further three minutes pass, a water temperature T3 is measured (S55, S56). Then the temperature difference ΔT=T3-T1 is calculated (S57). The estimated period of time required for the washing operation is found based on the values T2 and ΔT, and the estimated period of time required for the high-temperature rinse operation is found based on the values T0 and ΔT (S58). Then the period of time required for the rinse operation and the dry operation which have no relation to water heating is added to those estimated periods above to find the remaining period (S59).  Even if the washing compartment has remaining heat, as the water temperature is hardly affected by the remaining heat at the start of the washing operation, T0 almost reflects the temperature of fed water. Therefore, the period of time required for the high- temperature rinse can be accurately estimated without affected by the remaining heat, and the remaining period can be accurately displayed.

Title: Micro-capsule ink for pressure sensitive copying paper
Inventor: IGARASHI YURIKO
IPC: C09D11/00
Filed: 1986-05-14
Abstract: PURPOSE:To prevent a paper surface from becoming dirty and a coating surface from being roughened, by a method wherein micro-capsules including a solvent containing no dye are formed in a polynuclear arrangement and to be larger than dye-containing micro-capsules in average particle diameter. CONSTITUTION:A micro-capsule ink contains micro-capsules B having high pressure resistance and a polynuclear form and including a solvent containing no dye. The average particle diameter of the capsules B is made larger than that of compatible micro-capsules A including a dye solution. If a pressure sensitive copying paper coated with the ink is applied with friction in storage, the capsules B are broken first to decrease the friction energy; thus, there is no possibility that the break of the capsules A causes a dirty paper surface. On the other hand, even when being used in a partial coating by a press such as flexographic printing, gravure, and typographic printing press, the ink smoothly transfers onto a roll to keep a coating surface from roughening; thus, the uniform coating surface is obtained.
