A heat treatment system disclosed herein may include: one or more saggars, each of which is configured to accommodate powder of a lithium positive electrode material; and a heat treatment furnace configured to heat-treat the powder accommodated in the one or more saggars. Each of the one or more saggars may include a contact surface which is to make contact with the powder, wherein at least the contact surface of each saggar is constituted of a nickel-based alloy. The heat treatment furnace may be configured to heat-treat the powder accommodated in the one or more saggars at a temperature of 300° C. or more and 1000° C. or less for a duration of 10 hours or more and 30 hours or less.

Heat treatment system, saggar and method of heat-treating

An infrared heaterincludes a heating elementthat emits infrared radiation when heated and that is capable of absorbing infrared radiation in a predetermined reflection wavelength range, and a filter unitthat is disposed so as to be separated by a first space, which is open to an outside space, from the heating element. The filter unitincludes one or more transmission layers (a first transmission layer) that transmit at least a part of the infrared radiation from the heating element, and a reflective section (the first transmission layer) that reflects infrared radiation in the reflection wavelength range toward the heating element

Infrared heater and infrared processing device

A low-temperature drying apparatus includes a furnace body, an object holder, an infrared light transmitting plate, a supply device, a discharge device, and infrared heaters. The object holder holds an object to be dried so that the object to be dried is placed in the furnace body. The infrared light transmitting plate is arranged on a surface of the furnace body that faces the object holder. The cooling flow generating device generates a cooling flow in a space between the object to be dried that is held by the object holder and the infrared light transmitting plate. The infrared heater is disposed to face the infrared light transmitting plate in an open space outside the furnace body.

Low-temperature drying apparatus

There is disclosed a method of inspecting the outer wall of a honeycomb structure body which can be performed without relying on human sensory functions and in which a defect detection level and an inspection time per honeycomb structure body are constant, so that stable inspection can be performed. In a method of inspecting the outer wall of a honeycomb structure bodymade of a ceramic material, while rotating the honeycomb structure body, the outer wall of the honeycomb structure bodyis imaged by a line camera, and the thus obtained image is processed to judge whether or not a defect is present in the outer wall of the honeycomb structure body
