This paper proposes a novel approach to train word embeddings to capture antonyms. Word embeddings have shown to capture synonyms and analogies. Such word embeddings, however, cannot capture antonyms since they depend on the distributional hypothesis. Our approach utilizes supervised synonym and antonym information from thesauri, as well as distributional(More)
A noncontact transfer device using a combination of ultrasonic levitation with flexure traveling wave has some advantage in clean environment and simple device configuration. This paper deals with the concept of a two-dimensional transfer device using ultrasonic levitation, and fundamental experiments. A prototype of a one-dimensional transfer device was(More)
INTRODUCTION Noncontact transfer devices are demanded when silicon wafers or glass plates are carried in clean environment. Because contact of such products with a conveyer belt damaged their surface, non-contact transfer devices are needed for the use in clean environment. Many transfer devices using ultrasonic, electromagnetic or electrostatic levitation(More)
