Patent number: 11926502Abstract: A transport device transports an individualized sheet-shaped workpiece. The transport device includes: an annular transport belt having a first surface and a second surface opposite to the first surface and having a plurality of suction holes extending between the first surface and the second surface; first and second decompression chambers arranged along a moving direction of the transport belt; and a vacuum degree adjusting mechanism provided in the first decompression chamber and adjusting a vacuum degree in the first decompression chamber. The first and second decompression chambers each abut against the second surface, and each suction the workpiece through at least one of the plurality of suction holes toward the first surface such that the transport belt is capable of transporting the workpiece in the moving direction in a suspended state from the first surface.Type: GrantFiled: July 12, 2021Date of Patent: March 12, 2024Assignee: PANASONIC INTELLECTUAL PROPERTY MANAGEMENT CO., LTD.Inventors: Kentarou Adachi, Takafumi Kaneda, Hayase Minoura, Masaki Takahashi

Patent number: 10717896Abstract: The present invention relates to a curable heat radiation composition which includes two types of fillers with different compressive breaking strengths (except when the two types of fillers are the same substance) and a thermosetting resin, the compressive breaking strength ratio of the two types of fillers [compressive breaking strength of a filler (A) with a higher compressive breaking strength/compressive breaking strength of a filler (B) with a lower compressive breaking strength] being 5 to 1,500, the compressive breaking strength of the filler (A) being 100 to 1,500 MPa, and the compressive breaking strength of the filler (B) being 1.0 to 20 MPa, an adhesive sheet using the composition and a method for producing the same. An aluminum nitride is preferable as the filler (A) and hexagonal boron nitride agglomerated particles are preferable as the filler (B).Type: GrantFiled: June 20, 2017Date of Patent: July 21, 2020Assignee: SHOWA DENKO K.K.Inventors: Yoichiro Sakaguchi, Kentarou Takahashi, Keisuke Mameda
