Title: Electric water heater
Inventor: SHIMADA KAZUYUKI
IPC: A47J27/21
Filed: 1992-09-16
Abstract: PURPOSE:To prevent a vessel and a thermal sensor element from deforming or changing the color with heat, by decreasing the rising temperature in the vessel without reheating until water is added in the vessel when once heated without water in the vessel. CONSTITUTION:An electric water heater is provided with a heater 2 to heat the liquid in a vessel, a thermal detector 3 to check the temperature of the liquid in the vessel, a current conduction means 4 for the heater, a driving means 5 actuating the current conduction means, and a starting means 9 of heating for the driving means. When the current conduction means 4 is actuated, a disconnecting means 6 stops the current conduction means 4 if the rising time of the temperature measured by a measuring means 7 is shorter than a specified interval and the driving means 5 is continuously prohibited to work. When the disconnecting means 6 is once actuated, the disconnecting means 6 keeps to work until the controller 8 detects the decrease of temperature. When the controller detects the decrease of temperature, the disconnecting means 6 ceases to work.

Title: Record retrieving mechanism in network type data base
Inventor: KIKUCHI TETSUO
IPC: G06F17/30
Filed: 1988-09-30
Abstract: PURPOSE:To prevent idle reading and to improve access efficiency by preparing a record type referring file from a real data base, referring this file and reading the realizing value of a designated master record type. CONSTITUTION:A record type referring file preparing mechanism 2 once reads the real data base of a network type data base 1 and prepares a record type referring file 3. When the designating information of a retrieving subject record type and the request information of a master record position are received from a record taking-out mechanism 6, a master record position returning mechanism 4 successively reads the position of the real data base for the realizing value of the designated master record type from a head according to a request and returns the position to the master record taking-out mechanism 6. Thus, even when the real data base is accessed and a master record is successively taken out, idle reading is not generated to the real data base since the record realizing value to be next accessed is speedily known. Then, the access efficiency is improved.

Title: Contamination preventing ozone injection in marine temperature difference power generation plant
Inventor: SUMITOMO HIROYUKI
IPC: F03G7/05
Filed: 1989-09-22
Abstract: PURPOSE:To obtain an intial contamination preventing effect efficiently with a small quantity of ozone by dissolving ozone in lower layer brine primarily to obtain high density ozone brine, and injecting it to an upper layer brine line. CONSTITUTION:In supplying lower layer brine to a condenser as a cooling source, a part of it is branched to be injected to a predetermined position of an upper layer brine line through an ejector 22. At that time, the lower layer brine passing the ejector 22 sucks ozone from an ozone generator 20 as drive water. The lower layer brine coming out of the ejector 22 is high density ozone brine in which ozone is primarily dissolved to be injected to the predetermined position of the upper layer brine line. An initial contamination preventing effect can thus be obtained efficiently using only a small quantity of ozone.
