Abstract: Normally a speaker is used by attaching to a sealed or semi-sealed cabinet so that vibration generated at the front and the back of a diaphragm does not mutually interfere. Therefore, a certain depth and a volume are necessary, and in a limited location such as a front panel of a device, there is a case that it cannot be attached to the most suitable position for a listener. As a means to solve that, a method that a speaker sound at a distant position is led to a front panel by a waveguide is practically used. However, still it has limitations in depth and attaching position, and good results cannot be obtained also in efficiency. A speaker is attached so that a sound generated at the front of the speaker attached to a cabinet is led to a plane such as a front panel of a device by a waveguide, and the opening surface of the waveguide is almost perpendicular to the plane.

Abstract: A hand-held massager capable of self-excited, impedance-matched vibration for optimal massaging of each particular body part of each particular individual. The massager includes a hollow, open-ended contact piece to which is coupled a vibrator and which is to be held against a desired body part. A pressure sensor is mounted to the contact piece for sensing pressure variations in the cavity in the contact piece while the open end thereof is held against the body part, in order to ascertain the mechanical impedance of that body part. A closed-loop, electropneumatic vibration control system makes it possible for the mechanical impedance to be fed back to the vibrator, causing the latter to make self-induced vibration. Thus the desired body part is optimally massaged at its resonance frequency.

Abstract: A closed pneumatic sound sensor is incorporated in a driver's seat and catches a signal representative of a movement of the body of the driver, and a continuation time period within which the level of the signal does not reach a fixed level is detected. Simultaneously, a signal which is generated only when the vehicle is running is caught from the vehicle, and the two signals are compared with each other by an arithmetic operation circuit. Only when both of the signals are present and a particular tendency appears in the continuation time period of the signal representative of a movement of the body, an alarm is generated. A less expensive doze-at-the-wheel alarming apparatus which does not require cumbersome mounting and does not operate when the vehicle is not running is provided.

Abstract: A method for diagnosis of components inside a turbine generator includes collecting and measuring organic substances present in a gas inside the turbine generator to obtain data (first data). Before the collecting, organic substances generated from each component inside the turbine generator due to heat, discharge, corrosion, or friction, are measured to compile data (second data). The first data is compared to the second data to determine whether the first data includes the same data as in the second data to detect deterioration of the components inside the turbine generator.

A biasing pressure controlling means controls the biasing force exerted by a biasing means upon the blood flow through the artery and is responsive to the output of the second level detecting means.
