  • Patent number: 9608397
    Abstract: Provided is a laser processing device capable of performing high-power laser processing while preventing reduction of life duration of a light source for excitation light. By collecting the light emitted from single emitters of a plurality of single emitter LDs onto one end face of an optical fiber cable, high-power excitation light is transmitted to a marking head through the optical fiber cable. Excitation light emitted from the other end face of the optical fiber cable is separated into first excitation light and second excitation light. The first excitation light excites a first laser medium to generate laser light. The generated laser light enters a second laser medium. The second excitation light enters the second laser medium. With this, the second laser medium is excited, and the laser light that has entered the second laser medium from the first laser medium is amplified.

  • Patent number: 9460699
    Abstract: An electronic percussion instrument includes a head, a frame, and an impact sensor, and a plate serving as a vibration-damping member. The back of the head is divided into a main area (e.g. a main strike area) and an auxiliary area. The plate is ring-shaped sheet, made of a harder material (e.g. a metal) than the head, with an elongated hole and attached to the head to encompass or sandwich the main strike area of the head, thus demonstrating a vibration-damping effect. When the main strike area of the head is being struck with a beater, a vibration is caused to occur in the head and detected by the impact sensor to produce an electric signal which is used to generate an electronic musical sound while the vibration-damping member suppresses vibration being transmitted through the head due to an impact of the beater on the head.

  • Publication number: 20160143331
    Abstract: A liquid food composition that can be conveniently ingested or given by tube feeding, and can prevent gastroesophageal reflux disease, vomiting, esophagitis, pneumonia, asphyxiation, diarrhea, etc., and can increase feeling of fullness through improvement in the solidification ratio of the composition under the endogastric condition is provided. Since the liquid food composition of the present invention shows superior solidification ratio under the endogastric acidic condition, it can more effectively reduce the risks for developing gastroesophageal reflux disease, vomiting, esophagitis, pneumonia, asphyxiation, diarrhea, etc., and it does not require labor for separately adding a gelling agent etc. at the time of ingestion, and since it is liquid, it can be easily ingested by tube feeding.
