Patent number: 11346859Abstract: A contact probe is conductive and capable of expanding/contracting along an axial line direction. The contact probe includes: a first contact member configured to contact one contact target; a second contact member configured to contact another contact target, and to house at least a portion of the first contact member; and a spring member configured to couple the first contact member and the second contact member in a manner capable of expansion/contraction with both end parts of the spring member. The spring member is wound in a helical shape, and at least a diameter of an outer circumference in one of the end parts held by the second contact member is larger than diameters of other portions. A diameter of an inner circumference of an end part of the second contact member on a side housing the first contact member is equal to or larger than a maximum diameter of the first contact member.Type: GrantFiled: March 29, 2018Date of Patent: May 31, 2022Assignee: NHK Spring Co., Ltd.Inventors: Kazuya Souma, Tsukasa Sakaguchi

Patent number: 7007087Abstract: The service use requirement issue from the user is rejected by holding the threshold value for starting and releasing the service reject in response to the load in the side for providing the information communication service and multicasting the service reject information including the device in the users who do not issue the service requirement using the route with which each user transmits the requirement to the information communication service system when a load in the side for providing the information communication service becomes high and it is determined that the service reject is started. As explained above, when an information service system such as the shopping service system is placed in the overload condition, the service use requirement can be rejected from the user side device to ease the load of the service provision system.Type: GrantFiled: August 24, 2000Date of Patent: February 28, 2006Assignee: Hitachi, Ltd.Inventors: Kazuya Souma, Akira Mineo, Kenji Kimoto
