Abstract: PURPOSE: To provide a display panel of a meter with which a bright display of a thin type is obtainable. CONSTITUTION: The radiated light rays from small-sized light source elements L1 to L3 are introduced from the light incident surfaces 181 to 183 of light introducing parts 171 to 173 into a light scattering light transmission body. The light rays introduced into this light scattering light transmission body are guided as a whole toward the central part while these light rays are subjected to the effects, such as scattering in the inside, scattering by the white ink parts 191 to 193 and reflection on the inside surface of the light exit face, in combination.

Abstract: PURPOSE:To improve the convenience and the availability of a facsimile communication system by accepting a polling holding display signal from the corresponding terminal with a facsimile communication request received in a busy state of a store and forward exchange and then receiving the polling from said terminal when a circuit becomes idle. CONSTITUTION:When a call is given to a store and forward exchange 2, an I/F part 21 gives a request to a system control part 24 for connection to a circuit. When the circuit is busy, this information is given to a facsimile terminal I1. Then a tone signal detector of the part 21 detects a polling holding signal within a prescribed time. Thus the part 24 waits for an idle channel. When the exchange 2 has an idle channel, the part 24 gives a request for polling reception to the terminal FI1 of the transmission side registered in a memory 25. Then a facsimile terminal FO1 of the reception side is called and the picture information stored in the memory 25 is transmitted by a normal facsimile transmission procedure.

Title: Smoke detector
Inventor: YAMAMOTO RIYOUICHI
IPC: G08B17/10
Filed: 1978-12-18
Abstract: PURPOSE:To detect mist highly sensitive, by a mechanism wherein a light source, a means for focusing radiant light from the light source and a light receiving portion with a non-sensitive portion to light at a focusing location are mounted and smoke is let flow between the light source and the focusing means. CONSTITUTION:When there is no smoke, a light receiving element 29 does not transmit signals to an alarm circuit 30 because light passing through a small hole 23 is concentrated onto a light shielding portion 28 by means of a focusing lens 25. Meanwhile, when mist enters into beams radiated from the small hole 23, smoke particles 24 disperse light, and the scattered light 27 is not projected to the light shielding portion 28, and is projected to the light receiving element 29, thus forwarding signals, which inform of the existence of smoke, to the alarm circuit 30 by means of the light receiving element 29. Thus, smoke can be detected highly sensitive because not only scattered light in the specific direction but also scattered light over a wide range can be utilized.
