摘要:
There is provided a ceramic member which is a sintered body containing enstatite and boron nitride as constituents, in which boron nitride is oriented in a single direction, a probe holder formed using the ceramic member, and a manufacturing method of the ceramic member. In the ceramic member, an index of orientation degree is not less than 0.8. In so doing, it is possible to provide a ceramic member which has a free machining property, a coefficient of thermal expansion which is close to that of silicon, and high strength, and a probe holder which is formed using the ceramic member, and a manufacturing method of the ceramic member.

摘要:
An aircraft seat which can receive the load of a sitting person with only a back plate member, using no seat back frame, thus eliminating the need for sacrificing the sitting space, which results from the existence of the seat back frame, and at the same time, allowing the weight of the seat to be reduced, is provided. The aircraft seat (1) on which an aircraft passenger is to sit comprises a seat back (10) made up of a back plate member (11) that a cushion (12) is installed onto a front face (11a) thereof for receiving the back of a sitting person, and a reinforcing member (13) which is disposed on the rear face (11b) of the back plate member (11) for reinforcing the back plate member (11), and said back plate member (11) is formed in the shape of a curved surface which enhances the surface rigidity.
摘要:
A lithium ion secondary battery has an electrode group including: a winding core; and a positive electrode and a negative electrode that are wound around the winding core. This electrode group does not have an independent separator between the positive and negative electrodes. A porous film is integrally formed on both sides of at least one of the positive electrode and the negative electrode. The negative electrode and the positive electrode are connected to the winding core by a negative electrode resin film and a positive electrode resin film, respectively. The use of such resin films makes it possible to reduce the breakage of the porous films and prevent a short-circuit between the positive and negative electrodes.
