摘要： A smoke sensing device of the type having a single ionization chamber wherein stability and reliability are increased by driving the ionization chamber from a square wave oscillator, and utilizing an A.C. amplifier responsive to the ionization current within the chamber. The A.C. amplifier serves to amplify the current through the ionization chamber and couple the amplified current to a rectifier and detector adapted to respond to decreases in current, such as caused by smoke particles within the ionization chamber, to activate an alarm device.

摘要： An ionization type smoke sensing device includes a printed board. An inner electrode made of heat-resistant metal is attached to the printed board and a radioactive source is fixed to the inner electrode. An outer electrode in the form of a bottomed cylinder made of heat-resistant metal and adapted to cover the inner electrode extends through the printed board and is integrally joined to a protective lid member made of heat-resistant metal at the back of the printed board. Therefore, the outer electrode and the lid member cooperate with each other to define an ionization chamber. The outer electrode is formed with smoke inlet ports for introducing smoke into the ionization chamber. The electric circuit serves to give pulse signals of a relatively high voltage to the outer electrode and to detect the presence of smoke on the basis of the amount of a current flowing through the inner electrode.

摘要： A light scattering type smoke detector minimized in size and protected from erroneous operation and from internal accumulation of water drops is provided. The optical comprises light emitting and receiving elements and light shielding means which are compactly mounted on a base plate at different heights so as normally to prevent light from the emitting element to reach the receiving element. A power source part for the light emitting element disposed at one side of the optical system and an amplifying part for the light receiving element disposed at the other side of the system are housed in an upper lid having drain means, and a lower lid having many small holes for smoke lead-in is attached to the upper lid.

摘要： An object detecting apparatus has a plurality of light emitters which are sequentially actuated for projecting sequential light beams. A first structure is provided for receiving beams not reflected off any external body. A second structure is provided for receiving any part of the light beams reflected from an object in the area. A reference phase signal corresponding to the projected light beams is generated. A detection phase signal corresponding to the received reflected beam is also generated. The light emitters corresponding to the reflected light beams are continuously activated. The detection area is restricted by inhibition of output from an alarm phase difference discriminating circuit to a circuit when a difference between the reference and detection phases is not within a predetermined range. Consequently, the detection area can be restricted to a desired range, and the alarm circuit can be retained non-operative unless the object remains continuously in the area. This avoids any malfunction produced by any transitory object, while the actuation of the light projecting means in a very short time sequence accelerates the detecting operation with minimized power consumption.
