Abstract: An object of the present invention is to provide a conversation support apparatus and a conversation support method that allow users to effectively and smoothly onverse with each other. According to the present invention, since a first display section 22 and a second display section 32 can be placed at different angles, while a first user is watching the second display section 32 and a second user is watching the first display section 22, they can smoothly converse with each other. Since the first display section 22 and the second display section 32 are disposed, for example the second user and the first user can face-to-face converse with each other.

Abstract: An object lens includes a first optical system that obtains a magnified image of an object, a second optical system that guides dark field illumination light to the object, a barrel that contains the first optical system and the second optical system and has an optical path around the first optical system for the dark field illumination light, and a shield mechanism that is disposed on the optical path and that varies the incident area of the dark field illumination light to shield the dark field illumination light.

Abstract: To provide a stethoscope apparatus that can contribute to medical cares that can eliminate anxieties of a patient as much as possible. A stethoscope apparatus 10 according to the embodiment integrally mounts a speaker 9 and a microphone 8; accordingly, the speaker 9 can reproduce sounds obtained with the microphone 8. For instance, when a physician explains the pathology and so on to a patient with the patient allowed hearing sounds from a speaker, the patient can be diagnosed at ease more than ever.

Abstract: An object of the present invention is to provide a technology that improves the safety of a handicapped person when he or she goes out. In addition, another object of the present invention is to provide a technology that generates route information or surrounding information that a handicapped person can easily understand. A mount device 20 mounted to the head of a handicapped user 5 acquires information in the eye level of the user. A portable device 30 that the user 5 holds with his or her hand acquires information in the forward foot level of the user. Thus, since more detailed information can be acquired, the safety of the user 5 who goes out is improved.

Abstract: To provide an object lens and a condenser that allow an observation to be performed more microscopically than dark field observation. A plurality of shield plates 8 are rotatably disposed at a fit portion 3a of an object lens 100 in the vertical direction of an optical axis so that the shield plates 5 can be opened/closed. Thus, dark field illumination light that passes through an optical path 5 can be shielded. In addition, the incident area and incident direction of the dark field illumination light to a ring-shaped lens 6 that emits the dark field illumination light to an object can be varied. As a result, microscopic flaws, unevenness, and foreign matter that cannot be detected by the conventional dark field observation can be observed and directional flaws can be observed.

Abstract: A patient registers his audible sound when he is in good health. When he is not feeling well, and even when he is in good health, he may contact regularly with a medical institution. Once he pronounces words to his mobile phone, the audible sound will be stored in a storing portion for storing audible sound information of the patient and will be processed by a computer that gives diagnosis to the patient and the patient will be informed of the diagnosis through a public line.

Abstract: [OBJECT] To provide a keyboard instrument that is easy for a beginner to use and less in the cost. [MEANS FOR SOLVING] A keyboard instrument 10 includes a keyboard portion 4 constituted only of keyboards 21 in which tone intervals are arranged so as to repeat an arrangement of whole step, whole step, half step, whole step, whole step, whole step and half step. That is, without disposing black keyboards that can alienate a beginner from a keyboard instrument 10, the respective keyboards 21 are arranged. Thereby, while securing the respective keyboards 21 necessary for performing a piece of music, a beginner is allowed lightheartedly addressing a keyboard instrument 10 and playing readily. Since the number of keyboards 21 preparing for manufacturing a keyboard instrument 10 can be reduced, the lower cost can be achieved.

Abstract: When a digital camera is used on the side of a C-mount section of a microscope, the digital camera is attached to the C-mount section of the microscope with a C-mount adapter and an optical adapter between them. When the digital camera is used on the side of an ocular section of the microscope, the digital camera is attached to the ocular section of the microscope with the optical adapter between them.
