摘要： A torque detector for detecting a torque applied to a torque transmission shaft which is connected to a load such as a wheel of an automobile. A first rotating body is connected to one end of a driving shaft of an engine coaxially, and an annular second rotating body is disposed around a boss which projects from the center of the first rotating body so as to be coaxial and parallel with the first rotating body. An elastic member connects the inner peripheral portion of the second rotating body to the boss in the radial direction. The angular phase difference between the first and the second rotating bodies which occurs due to the deformation of the elastic member is detected, and torque is calculated from the obtained angular phase difference.

摘要： A collision detection device has a weight, which includes an eccentric mass and a metallic plate. The weight is pivoted by a shaft at a position eccentric from the mass barycenter to have a predetermined swing velocity and frequency response. A rotor is fixed to the weight, and contact springs having contacts are provided to exert a resilient force to the weight. When the acceleration caused by the impact of collision acts on the weight, it swings against the spring force, and bounces on a stopper to swing back. The rotor which swings together with the weight causes the contacts on the springs to close at a certain swing angle, producing a collision detection signal. The eccentric mass and the metallic plate may be provided to swing separately from each other depending on the magnitude of acceleration.

摘要： In a smoke sensing apparatus, a light receiving circuit including a light receiving element senses light emitted from a light emitting circuit including a light emitting element and scattered by smoke, and a voltage holding circuit converts the output signal of the light receiving circuit into a d.c. voltage and holds the d.c. voltage. A mean value circuit averages the voltage signal from the voltage holding circuit, and a switching circuit acts to bring the output of the mean value circuit to a level close to that of the output of the voltage holding circuit. A comparison circuit compares the output of the means value circuit with the output of the voltage holding circuit thereby generating a control signal.

摘要： In a housing having a cylindrical bore, an inertia sensing weight is slidably disposed. At one end of said weight, a movable contact is normally carried in complementary engagement thereby separating from a stationary contact.When the weight moves under acceleration or deceleration, the movable contact accompanies the weight until the movable contact abuts the stationary contact. In the illustrated embodiment there is a second stationary contact normally separated from the first one. The movable contact, when closing, abuts both of them, making an electrical circuit therebetween.
