Title: Water heater
Inventor: TAKASHIMA KATSUTOSHI
IPC: F23N1/02
Filed: 1999-08-23
Abstract: PROBLEM TO BE SOLVED: To reduce an undershoot when switching a combustion stage. SOLUTION: The water heater is operated by the steps of starting supplying of hot water (S1), and deciding whether a required input amount is an input amount necessary to switch to a combustion stage of a large capability side or not (S2). Here, when the required amount is the amount necessary to switch to the stage, the amount is switched to the stage of the large capability side, burned at the maximum combustion amount at this stage, and a flame carry- over is conducted (S3), and the amount is burned at the required input amount (S5). Meanwhile, when the decision results in no input amount necessary to switch to the stage of the large capability, the flame carry-over is conducted by a preset slow ignition combustion amount (S4), and the required amount is burned (S5).

Abstract: PURPOSE:To completely prevent information recorded inside an identification card (IC card) from being read out wrongly and also to improve the security, by providing a means to set a flag when a test is through and a data line cut-off means. CONSTITUTION:When various types of tests are carried out with a data memory 26 of an IC card 10, the reading signal to read the output of an inverter 183 into an address line 321 of a 1-bit memory 32 is applied. Thus the single output is read into the memory 32 and a flag is set and then the output of the inverter 183 is inverted to '0'. Thus a data line 182 is cut to prevent the contents of the memory 26 from being read out wrongly via the line 182. Furthermore the address supplied from a system bus 11 is compared with a specific address of a fixed address part 30 through a comparator 29. When the coincidence is obtained between both addresses, all memory area of the memory 26 are cleared via a read/write controller 18.

Title: Snow melting device
Inventor: INOUE HITOSHI
IPC: E01C11/26
Filed: 1989-09-13
Abstract: PURPOSE:To improve the snow melting faculty by installing a heat radiation panel which is thermally attached with one side of a heat pipe arranged in a snow storage groove and installing a heat insulating body for suppressing the useless heat radiation of the heat radiation panel onto the undersurface of the heat radiation panel. CONSTITUTION:One edge side 9a of a heat pipe 9 is heated by the heat in the soil 2, and the working fluid in the heat pipe 9 is vaporized, and transferred to the other side 9b of the heat pipe 9 arranged in a snow storage groove 7 through the inside of the heat pipe 9. Since the temperature of a heat radiation panel 10 arranged in the snow storage groove 7 is lower than that of the soil 2, the vapor of the working fluid is condensed and liquefied, and liberates the condensation latent heat into the heat radiation panel 10 arranged in the snow storage groove 7. Further, the useless heat radiation under the heat radiation panel 10 is suppressed by installing a heat insulating body 11 onto the undersurface of the heat radiation panel 10. Further, the liquefied working fluid is returned to one side 9a of the heat pipe 9, and the heat radiation panel is heated by the repetition of the above-described operations, and snow can be effectively molten.
