Abstract: A grease injection valve 10 is provided having a valve body 16 including a flow path 15 the valve body. A foreign matter intrusion prevention valve 18 is provided at the upstream side of a check valve 17 in the flow path 15 of valve body 16. Grooves 47 are positioned around the periphery of a foreign matter intrusion prevention valve body 44 in the flow path 15 to provide communication between the downstream side and the upstream side of the foreign matter intrusion prevention valve body 44. When the check valve 17 has a functional failure, high-pressure grease escapes through the grooves 47 to bypass the foreign matter intrusion prevention valve body 44 and is discharged to an exterior of the grease injection valve 10. This can avoid excessive pressure caused by the grease backflow from being applied to the foreign matter intrusion prevention valve 18.

A second surface of the vibrating plate includes a plurality of groove regions extending radially, and the depths of the groove regions change in a circumferential direction along a curve obtained by superimposing one or more sine waves on one another. The ultrasonic motor exhibits a sufficient drive speed while suppressing generation of an unnecessary vibration wave.

Abstract: A distribution unit (101) distributes to a customer a coupon for which a valid term is set. Upon receipt of an inquiry about the valid term set for the coupon from the customer to whom the coupon was distributed, an extension unit (102) acquires the valid term set for the coupon from a distributed coupon DB (122). Then, if the acquired valid term has elapsed, the extension unit (102) extends the valid term set for the coupon. In addition, the extension unit (102) determines the period of the extension based on at least a total number or total value of coupons which were distributed to other customers and for which valid terms that have not yet elapsed were set. A reply unit (103) replies to the inquiry with the valid term set for the coupon.
