Abstract: A non-transitory computer-readable storage medium storing a program that causes a processor included in an information processing apparatus to execute a process, the process includes storing answer information that is information regarding an answer to a question, and identification information for identifying a user who is permitted to use the answer information, in a case where use of the answer information is requested, determining whether or not identification information of a user who is a requestor is stored, and in a case where the identification information of the user who is the requestor is stored, transmitting the answer information to the requestor.

Abstract: A tip end part of a main arm member of a Scott Russell mechanism is enabled to be brought close to a base end part of a sub arm member. A Scott Russell mechanism device is formed into a boomerang-like shape such that a main arm member coupled to a sub arm member is curved to detour a coupling position. Thus, when the coupling angle is changed so that a base end part of the main arm member and a base end part of the sub arm member are most separated from each other, a tip end part of the main arm member can be moved close to right beside the base end part of the sub arm member. With the Scott Russell mechanism device, a moving range of the tip end side of the main arm member can be enlarged.

Abstract: A joint unit pivotably coupled to a tip end part of a main arm member of a Scott Russell mechanism is pivoted in two ways. A Scott Russell mechanism device pivotably couples a main arm member and a sub arm member to each other, as well as it pivotably couples a joint unit to a tip end part of the main arm member. Moreover, by providing a pivot driving unit to the main arm member, as well as providing a fourth motor and a drive transmission mechanism unit to the sub arm member, the Scott Russell mechanism device can switch between pivoting the joint unit associatively a change of a coupling angle of the arm members and pivoting the joint unit by the drive of the fourth motor.

Abstract: The device has a rotary drum provided with a plurality of guide recesses, an outer cylindrical plate surrounding the rotary drum and a helical bar disposed between the outer peripheral surface of the drum and the plate. Containers are lowered and lifted along the bar while being moved up and down in the respective guide recesses.

Abstract: A device for retrieving data such as individual names, firm names, addresses, telephone numbers, and so forth, which is constructed in a handy and compact type, and which comprises a rotatable data recording member having a plurality of data indicating parts, a plurality of data retrieving members corresponding to the data indicating parts of the rotatable data recording member, a drive mechanism to rotate the data recording member, and a control mechanism to cause the drive mechanism to stop by operating one of the data retrieving members, and to cause the data indicating parts of the data recording member to the data retrieving member to be presented for reading out.
