Title: Method for recycling steel making dusts in electric furnace having scrap preheating furnace
Inventor: MAKINO NOBUYUKI
IPC: C22B1/00
Filed: 1989-07-19
Abstract: PURPOSE:To allow the recycling of CaO-contg. steel making dust without pulverizing the dust by adding water to the dust, curing the dust, and pelletizing the same under addition of water glass thereto, then curing the pellets, heating the pellets together with scrap in a preheating furnace and charging the heated pellets into an electric furnace. CONSTITUTION:Water is added at about 3 to 15wt.% to the CaO-contg. steel making dust under agitation and the dust is cured for about 1 to 2 days to prepare the pelletized raw material having about 2 to 10wt.% moisture content. The water glass is added to the pelletized raw material in such a manner that about 3 to 7wt.% water glass is incorporated therein. The raw material is then humidified, kneaded and pelletized to form the pellets having about 10 to 15wt.% moisture and about 3 to 30mm grain size. The pellets are cured for about >=1 days and are thereby hardened. The pellets are charged into the preheating furnace contg. the scrap and are heated up to the preheating temp. of the scrap; thereafter, the pellets are charged together with the scrap into the electric furnace. The effective recycling of the steel making dust is possible in this way without pulverizing the dust.

Title: Relay transmission result notice system for isdn terminal equipment
Inventor: OZEKI SHINICHIRO
IPC: H04N1/00
Filed: 1991-07-03
Abstract: PURPOSE:To reduce the line occupancy time by informing the result of relay transmission to a request station in terms of user information of a call setup message from a repeater station and allowing the request station to interrupt a call immediately when the request station receives the call setup message. CONSTITUTION:When a call setup message reaches, a repeater station sends a reply message and executes a prescribed transmission control procedure. In this case, the repeater station checks a received session user data SUD to discriminate whether or not the message represents a relay transmission command. When the relay transmission command comes, each information of the SUD is stored in a system memory 3 and the station receives picture information sent succeedingly and stores it to a picture memory 2. Upon the receipt of an interrupt message, the repeater station replies a prescribed message and interrupts the line once. Then the station makes calling sequentially to each reception station receiving the SUD and sends the stored picture to a reception station from which a reply message is returned. Thus, the line occupancy time is reduced to reduce the communication charge.

In addition, a surface, facing the detector 81, of the spherical glass 61 is formed in a concave lens-like shape to act as a condensing lens. The collected light passes through an emission filter 71 and is efficiently converged on an image surface of the detector 81.

Title: Device for signal in voice band
Inventor: KATO JUNYA
IPC: H04M3/02
Filed: 1996-06-27
Abstract: PROBLEM TO BE SOLVED: To provide an in-band ringer in which an error of a ringer is prevented even when a line is interrupted and a pattern of a ringer tone generated by a caller is reproduced with fidelity. SOLUTION: When the partiality of a signal from an exchange is inverted because of call reception and a ringer signal R1 is outputted, a tone generating control means drives 1st and 2nd tone generating means depending on an input of the ringer signal so as to control a ringer control signal of any tone to be active. When a line is interrupted during call reception and no tone is detected, since a tone detection means detects it, an alarm or the like is outputted and a ringer error is stopped.
