Abstract: A multiple dwelling house interphone system includes a collective entrance machine and dwelling room master devices. When a calling operation section is operated and a dwelling unit number of a calling destination is input, a master device speech control section of the dwelling room master device of the dwelling unit including a plurality of dwelling room master devices performs a calling control of transmitting a call signal to the dwelling room master device of the calling destination having its master device ID, and subsequently forming a speech path when a response operation of the dwelling room master device of the calling destination is performed. The calling and speaking to the other dwelling unit are allowed even in a state where another dwelling room master device of the dwelling unit itself has formed a speech path with the dwelling room master device of the other dwelling unit.

Abstract: A multiple dwelling house interphone system includes a communication management device that controls communication between the collective entrance machine and the mobile phone. The communication management device relays the communication to the mobile phone registered as a calling destination of the collective entrance machine to be linked to the dwelling room master device using a predetermined application based on a VOIP. When a predetermined registration operation to allow communication with the communication management device based on the VOIP is performed to link the mobile phone to the dwelling room master device, information list on mobile phones already registered relative to the dwelling room master device as a link target is transmitted from the communication management device having accepted the registration in addition to an application for a download, and the mobile phone that has downloaded the application displays the information list on a display section of the mobile phone.

Abstract: A multiple dwelling house interphone system includes a collective entrance machine and a dwelling room master device. Each automatic door requires an unlock operation to pass through for proceeding to each area, and a part of the areas are occupied by facilities other than dwelling units. The collective entrance machine includes a card information input section, and the automatic doors each include an unlock operation section for unlocking using the card medium. The collective entrance machine further includes a card authentication section, an unlocking door storage section, and a card information storage section. The card authentication section permits the unlocking by the card medium when the information input to the card information input section matches the information registered in the card information storage section. The permitted card medium enables unlocking the automatic door stored in the unlocking door storage section in association with the information of the card medium.

Abstract: A multiple dwelling house interphone system includes a collective entrance machine, a dwelling room master device, and a management master device. The collective entrance machine is for calling a visit destination by a visitor. The dwelling room master device is for responding to the call by a dweller. The management master device is for speaking with the dweller by a manager. The management master device includes a speech permissibility storage section and a speech control section. The speech permissibility storage section registers a permissibility of calling and speaking to the dwelling room master device for each dwelling unit. The speech control section controls the calling and speaking. The speech control section does not perform the calling control when a calling operation by the management master device is performed towards the dwelling room master device of a dwelling unit registered as “unpermitted” in the speech permissibility storage section.

Abstract: A multiple dwelling house interphone system includes a collective entrance machine and a plurality of dwelling room master devices. The collective entrance machine is for a visitor to call and speak to a dweller. The plurality of dwelling room master devices are for the dweller to respond to the call from the collective entrance machine. The dwelling room master devices each include an unlock button to unlock an entrance door through which the visitor enters the dwelling area from an entrance. Some of the dwelling room master devices have an automatic unlock mode that unlocks the entrance door without waiting for an operation of the unlock button when a call signal is transmitted from the collective entrance machine.

Abstract: A multiple dwelling house interphone system include a collective entrance machine, a dwelling room master device, a management master device, and a sensor. When the sensor detects the occurrence of the abnormality, an abnormality occurrence signal is transmitted from the dwelling room master device to the management master device, and the dwelling room master device and the management master device emit emergency alarms. The management master device includes a display section and a display control section. The display control section displays an alarm stop button to stop an emission operation on the display section when the abnormality occurrence signal is received and the emission is started. When the alarm stop button is operated, the display control section subsequently displays an emission source call button to call the dwelling room master device as a transmission source of the abnormality occurrence signal.

Abstract: A multiple dwelling house interphone system includes a collective entrance machine, a dwelling room master device, and a management master device. The management master device is installed in a manager room to speak with the visitor or the dweller. The multiple dwelling house interphone system has a reception mode in which a call to any dwelling unit from the collective entrance machine is uniformly transmitted to the management master device. The management master device includes a forwarding button and a forwarding control section. The forwarding button re-forwards a call in the reception mode to an original calling destination. The forwarding control section re-forwards the call to the dwelling room master device of a dwelling unit as the original calling destination when the forwarding button is operated when a speech path is formed with the collective entrance machine in response to the call forwarded in the reception mode.

Abstract: An interphone system includes a slave device and a master device. The slave device includes a camera to obtain an image of a visitor. The slave device is for calling a dweller by a visitor. The master device includes a monitor to display a video image obtained by the camera. The master device is for responding by the dweller. The master device includes a video storage section, a mute setting button, and an operation control section. The video storage section records the video image. The mute setting button is for setting a silent mode in which a call sound is not emitted. The operation control section controls a silent mode operation, so as not to emit a call sound in response to a call from the slave device and to activate the camera to store the video image in the video storage section when the silent mode is set.

Abstract: A mat includes inorganic fibrous substances, first and second main faces, first and second side faces and intertwined portions. The intertwined portions respectively extend from needle piercing points of the first main face to needle piercing points of the second main face. A first virtual straight line and each of second virtual straight lines intersect with each other at a first angle of less than about 90° when viewed from the first side face to the second side face. The first virtual straight line and each of third virtual straight lines intersect with each other at a second angle of more than about 90° when viewed from the first side face to the second side face. The second virtual straight lines and the third virtual straight lines intersect with each other at a third angle when viewed from the first side face to the second side face.
