Inventor: SATO SHUJI
IPC: A47J27/21
Filed: 1996-10-18
Abstract: PROBLEM TO BE SOLVED: To make constant the quantity of hot water discharged per specified unit time even in case the water quantity in the vessel has lessened by changing the motor drive voltage upon receiving the output of means which senses the water quantity of the liquid in the vessel, and raising the motor drive voltage in such case as the water lessening. SOLUTION: A water heater is composed of temp. sensing means to measure the temp. of a vessel 1, heating means 3 to heat the liquid accommodated in the vessel 1 to bring it to the boil and make warm keeping at the specified level, and a hot water discharge pump 4a to discharge the liquid to outside the vessel 1, wherein the pump 4a is driven when current is fed to a motor 5. The impressed voltage on the motor 5 is changed by voltage changing means 11 upon receiving the output from water quantity sensing means 10 appearing at stages, where the impressed voltage is raised with decreasing water quantity in the vessel 1.

Title: Empty locker guidance
Inventor: YAMAJIYOU KAZUHIRO
IPC: G07F17/12
Filed: 1987-11-02
Abstract: PURPOSE: To improve service for users by saving labor for searching free locker by outputting the position of the closest free locker in voice when the user requests guide. CONSTITUTION: When the guide request of position of the free locker outputted by the user is reported to a controller 9, while receiving information from empty condition detecting means from 5-1 to 5-80 for lockers, the controller 9 finds the position of the free locker closest to the position of the user and dispatches that position information to a voice synthesizing means 8. The voice synthesizing means 8 edits a guide message from the position information and the free locker position closest to the user can be guided through voice output means from 4-1 to 4-5. Thus, since the place of the free locker closest to the position, where the user is located at present, is guided in voice, convenience for the user can be improved.
