Abstract: A liquid ejecting apparatus according to an aspect of the present disclosure has a nozzle configured to eject a liquid, a pressure chamber communicating with the nozzle, a piezoelectric element that varying pressure in the pressure chamber, an endless transport belt transporting a medium, an electrifying section electrifying the transport belt, and a driving circuit that supplying, to the piezoelectric element, a micro-vibration pulse that generates micro-vibration in the liquid in the pressure chamber without causing the liquid to be ejected from the nozzle. The micro-vibration pulse is varied according to first data related to the state of a meniscus in the nozzle in a first state in which the nozzle and the transport belt electrified by the electrifying section face each other.

Abstract: A liquid ejecting apparatus has a liquid-chamber, a fluid-chamber, a flexible member that includes a film and a first-seal-portion and that separates the liquid-chamber and the fluid-chamber, and a pressurizing section which supplies a fluid to the fluid-chamber to pressurize the flexible member toward the liquid-chamber. The fluid-chamber is configured such that a first-seal-portion being provided in the fluid-chamber and the first-seal-portion come into contact with each other to be partitioned into a first-fluid-chamber having an introduction port through which the fluid flows in and a-second-fluid-chamber. The pressurizing section converts, by the supply of the fluid to the fluid-chamber, a state of the fluid-chamber into a first-state in which the first-contact-portion and the first-seal-portion come into contact with each other or a second-state in which the contact between the first-contact portion and the first-seal-portion is released so that the first-fluid-chamber and the second-fluid-chamber communicate with each other.

Abstract: A sales management support system includes a first server, and a second server that is connected to the first server through a network, and installed in a store. When selling a drug/food to a customer, the second server compares contraindication-related ingredient information corresponding to the drug/food that is sold to the customer with the contraindication-related ingredient information corresponding to the drug/food purchased by the customer in another store based on the contraindication-related ingredient information stored in a second server-side storage section, and purchase history information transmitted from the first server in response to request information, and generates contraindication information corresponding to the comparison result, the contraindication information indicating contraindications to the drug/food combination, or precautions against the drug/food combination.

Abstract translation: 销售管理支持系统包括第一服务器和通过网络连接到第一服务器并且安装在商店中的第二服务器。 当向客户出售药物/食品时，第二服务器将与销售给客户的药物/食品相对应的禁忌证相关成分信息与客户购买的与其他药物/食品相对应的禁忌证相关成分信息进行比较 基于存储在第二服务器侧存储部中的与禁忌证相关的成分信息进行存储，并且响应于请求信息购买从第一服务器发送的历史信息，并且生成与比较结果相对应的禁忌信息，禁忌指示信息表示禁忌证 药物/食物组合或对药物/食物组合的预防措施。
