Title: Transmission reception system for privacy information
Inventor: HIROSE SHINTARO
IPC: H04N7/167
Filed: 1990-03-30
Abstract: PURPOSE:To decode privacy information by reading received revision information even when a contractor uses any storage medium before or after update and selecting automatically a key used for the time. CONSTITUTION:A specific address, a key K1 corresponding thereto, an update number R1, a key K2 and an update number R1+1 are stored in a card (a) distributed to a recipient, and a specific address, a key K2 and the update number R1+1, a key K2 and an update number R1+2 are stored in an update card (b). Even when the cards (a), (c) are used for a period P2, since a receiver reads the update number R1+1 and selects the key K2 corresponding thereto, the transmission information is correctly decoded. Since the information is received even when the recipient uses the card (c) before and after update over a long period, the operability of the recipient is much simplified and the possibility of disabled reception due to erroneous loading of the card around the period of the update is precluded.

Title: Electrode rod lift control device for arc furnace
Inventor: TADA SHIGEHIRO
IPC: F27D11/10
Filed: 1989-04-04
Abstract: PURPOSE:To make it possible to control arc current in a continuous and stabilized manner by providing a level detection means for a speed control signal, a speed compensation means to and a compensation signal to a speed reference output signal, and a control means to control a rise and fall in an electrode in the continuous mode. CONSTITUTION:When a level detection means 14, which detects a level of a speed control signal P, which is an output of an in-furnace resistance calculation means 5, judges whether or not the output P exceeds 5%. For example, when it judges that the output P exceeds 5% as a result of a sudden change in resistance induced by a conditional change or voltage fluctuations in a high voltage initial power receiving system, it outputs an OFF signal and turns off a gate circuit 15. Since it exceeds a dead band in this case, the output of the in-furnace resistance calculation means 5 is gain-controlled and then the controlled value enters an electrode lift control means 9 as it is so that the rise and fall of an electrode rod 18 may be continuously controlled. When it is within the dead band region, it is possible to inhibit fluctuations in extremely slight arc current, control the arc current so that it may be stabilized and obtain products having uniform quality by adding pulses, whose width is inversely proportional to the magnitude of electric current, to a high speed reference output signal.

Title: Production of artificial lightweight aggregate
Inventor: HARADA YOSHIKATSU
IPC: C04B14/02
Filed: 1997-04-03
Abstract: PROBLEM TO BE SOLVED: To obtain an artificial lightweight aggregate having high strength and low water absorptivity without causing melt sticking of a calcined product by subjecting the source granules for the artificial lightweight aggregate to first calcination, heat treating the granules at lower temp. than the first calculation, and then subjecting the granules to second calcination. SOLUTION: An artificial lightweight source material comprising 100 parts by mass of vitreous source material, 0.1 to 2.0 parts by mass of a foaming agent and 0.1 to 10.0 parts by mass of an adhesive is granulated to obtain granules having 5 to 15 mm diameter and 2,000 to 5,000 m<2> /g Blaine value. The granules are introduced through a kiln entrance 1 into an external heating type kiln 2. The granules are heated at 1,000 to 1,300 deg.C in a first heating part 7 for first calcination and then introduced into a second heating part 8 and heat treated for 2 to 10 min at a temp. lower by 50 to 300 deg.C than the first calcination temp. Thus the granules are introduced into a third heating part 8 and again heated to foam for 1 to 5 min at <(T1 +50) deg.C, wherein T1 is the first calcination temp.  Thus, the artificial lightweight aggregate is obtd., and the obtd. aggregate has 0.7 to 1.3 specific gravity in a dried state, <=10% saturation water absorptivity and >=800 N fracture strength.

Title: Machine word instruction translating method
Inventor: FUKUI AKINARI
IPC: G06F9/22
Filed: 1995-04-11
Abstract: PURPOSE: To reduce a capacity of a memory for storing an application program of a computer by decoding a read operation code (OP code) into a microinstruction after converting it into a defined conversion pattern when that OP code can be defined, but decoding that OP code into the microinstruction as it is in the other case. CONSTITUTION: A part in the code arrangement of the OP code is previously reserved as the OP code, that can be defined, and defined in a conversion table inside an OP code length converting circuit 7. Then, an OP code length discrimination circuit 6 discriminates whether the read OP code is the definable OP code defined in that conversion table or not. In the case of definable OP code, it is decoded into the microinstruction after being converted to the conversion pattern while referring to the conversion table, but when it is not the definable OP code, that OP code is decoded into the microinstruction as it is. Thus, the OP code of a machine word instruction having the high frequency of usage in the application program can be mapped into a much shorter definable OP code corresponding to the definition change of the conversion table.

Title: Radiation image detecting method
Inventor: HOSOI YUUICHI
IPC: H01L31/09
Filed: 1983-05-16
Abstract: PURPOSE:To eliminate a problem of adverse influence affected to the quality of a picture occurred in a mechanical carriage of a panel or a detector by photoelectrically reading out an intensity light via a photosensitive element, thereby shortening the detecting time in a radiation image converting method utilizing the intensity fluorescent unit, and simplifying the detection. CONSTITUTION:A photosensitive element 1 is, for example, formed of a photodiode 4 of a photoreceptor, and an MOS5 of a transfer unit. Radiation passed through an object is incident to a fluorescent layer side of a radiation image detector, and an electromagnetic wave of an exciting wavelength range of an intensity fluorescent unit contained in a fluorescent layer 3 is emitted. Then, the accumulated image of the radiation energy formed on the layer 3 is radiated as fluorescent (intensity light emission). This fluorescent light is proportional to the strong and weak radiation energy absorbed to the layer 3. Only the emitted fluorescent light is passed through the layer 2 of the filter to be photosensed by the photodiode 4 of the element 1, thereby generating a signal charge in the photodiode 4.

Abstract: PROBLEM TO BE SOLVED: To prevent an over-reach incoming call between base stations of other routes or other line sectors of the same route by avoiding a voice signal from returning to other command console through another base station. SOLUTION: A calling voice from a command console 1a to a train 5 is sent from a base station 43 to the train 5 and a tone signal is added to a head of a voice modulation signal to be sent in the case of the transmission. When the transmission signal over-reaches a base station 45, the base station 45 detects the tone signal from the received signal and disconnects a signal line 7 connecting to a command control 1b, then the received voice signal is not sent to the command console 1b through a central equipment 3 and a line exchange 2 thereby preventing an over-reach incoming call substantially.
