Patent number: 7062953Abstract: In a sampling tube-type smoke detector equipped with a smoke detection device detects smoke particles contained in the air suctioned from a monitored area through a sampling tube by an aspirator positioned in the downstream. The smoke detection device the sampling tube forms a lead-in tube and suctions air through the sampling tube in substantially a straight line. The lead-in tube is formed with a smoke sensor unit to detect smoke particles contained in the air. The aspirator comprises a rotating part which forms an actuator mechanism that discharges the air. The central axis of the lead-in tube and the rotational axis of the actuator mechanism of the aspirator are substantially on the same axis. The sampling tube-type smoke detector is provided to reduce pressure loss in the airflow traveling from the smoke detection device to the aspirator and to supply a low cost, compact smoke detection device driven by a small-sized fan.Type: GrantFiled: August 21, 2003Date of Patent: June 20, 2006Assignee: Hochiki CorporationInventors: Naoto Yamano, Yoshitaka Egawa

Patent number: 6960987Abstract: Disclosed herein is a fire alarm system for connecting a plurality of fire sensors to sensor lines, and giving an alarm in response to fire information output from the fire sensor in a line unit. The fire alarm system includes a current modulation section and an address specification section. The current modulation section is used for maintaining a current flowing in the sensor line at a predetermined value for a predetermined time at the time of a fire, and modulating the current in accordance with the inherent address information of the fire sensor. The address specification section is used for sensing fire information by judging whether or not the current has been maintained at the predetermined value for the predetermined time, and also for specifying the inherent address of the fire sensor that issued the fire information, from the modulated state of the current.Type: GrantFiled: September 19, 2002Date of Patent: November 1, 2005Assignee: Hochiki CorporationInventors: Manabu Dohi, Masahiko Nemoto, Naoto Yamano, Hiroshi Shima, Naoya Matsuoka

Patent number: 6522254Abstract: A smoke detector is provided with a light emission section holder having a light-emission element and a light receiving section holder having a light-receiving element. The light emission section holder and the light-receiving element are provided in a smoke detection section constituting a smoke detection space. The light emitted from the light-emission element is scattered by smoke entered the smoke detection space. The thus-scattered light is received by the light-receiving element,thereby detecting occurrence of fire. An insect screen is formed from soft fiber having a mesh pattern and is arranged so as to cover the entirety of the smoke detection section.Type: GrantFiled: October 31, 2000Date of Patent: February 18, 2003Assignee: Hochiki CorporationInventor: Naoto Yamano

Patent number: 6288647Abstract: A photoelectric smoke detector includes a smoke detecting section defining a smoke detecting space, a light emission section holder having a light-emission element disposed in the smoke detecting section, and a light receiving section holder having a light-receiving element disposed in the smoke detecting section. The light-receiving element receives light which has been emitted from the light-emission element and is scattered by smoke flowing in the smoke detecting space. A hybrid circuit board has an integrated circuit mounted thereon and is housed in the light receiving section holder. The integrated circuit including the light-receiving element and at least a received-light signal amplifying circuit. The hybrid circuit board is arranged so that the light-receiving surface of the light-receiving element is directed toward the smoke detecting space.Type: GrantFiled: October 31, 2000Date of Patent: September 11, 2001Assignee: Hochiki CorporationInventor: Naoto Yamano

Patent number: 5729207Abstract: A corrosive gas detecting sensor has a cartridge, a sensor body, and a connecting unit. The cartridge has a sensor element and a memory device. The sensor element changes its characteristic property when the sensor element contacts a corrosive gas, and the memory stores an initial value of the characteristic property of the sensor element. The sensor body has a control unit which detects a change of the characteristic property of the sensor element when the cartridge is connected to the body and outputs an indication of a fire when a rate of the change exceeding a preset reference value, the cartridge is detachably attached to the sensor body. The connecting unit electrically connects the cartridge with the sensor body when the cartridge is attached to the sensor body.Type: GrantFiled: December 23, 1996Date of Patent: March 17, 1998Assignee: Hochiki CorporationInventor: Naoto Yamano
