A linear heater is formed of an enamel wire composed of a heating wire and an enamel layer. The heating wire is made of a copper alloy containing silver, for example. The enamel layer is made of polyester imide (PEI), polyimide (PI) or polyamide imide (PAI), for example. The enamel layer is coated with an insulating coating layer. The insulating coating layer is made of fluororesin such as perfluoroalkoxy mixture (PFA), polyimide (PI), or polyamide imide (PAI). The linear heater is bonded to the lower surface of an upper toilet seat casing such that it is sandwiched between a metal foil and a metal foil made of aluminum, for example.

Toilet seat apparatus

Provided are a toilet seat device saving energy and accurately stabilizing the temperature of a seating section at a predetermined level in a short time, and a toilet apparatus having the same. A control section adjusts the temperature of a toilet seat section to 18&#xb0; C. when a heating function is turned on, and during a standby period D, the control section performs low electric power drive of a lamp heater provided at the toilet seat section. The control section starts 600 W drive of the lamp heater at time tafter the control section detects user's entry into a room, and the control section maintains the 600 W drive during an inrush current reduction period D. The control section starts 1200 W drive of the lamp heater at time tand maintains the 1200 W drive during a first temperature rise period D. After the temperature of the seating section reaches limit temperature, the control section starts 600 W drive of the lamp heater at time tand maintains the 600 W drive during a second temperature rise period D. After the temperature of the seating section reaches a temperature higher than a toilet seat set temperature, the control section starts low electric power drive of the lamp heater at time t

Toilet seat device and toilet seat apparatus having the same

A lithium primary battery including a positive electrode, a negative electrode, an organic electrolyte, and a separator interposed between the positive electrode and the negative electrode: the negative electrode including a negative electrode active material; the negative electrode active material being at least one selected from the group consisting of lithium metal and a lithium alloy; at least a surface layer portion of the negative electrode including a composite of amorphous carbon material and the negative electrode active material; and the surface layer portion facing the positive electrode with the separator interposed therebetween.
