Abstract: PURPOSE: To raise the geothermal-heat recovering efficiency, by employing an appropriate process through  classification of welling characteristics of a geothermal well into various patterns.   
     CONSTITUTION: A pipe 3 having a small diameter is inserted into a casing 2 of a production well 1 until it  reaches the bottom 4 of the well. The portion between the top end of the pipe 3 and the opening end of the  casing 2 is closed by an annular plate 5, thus forming a cylindrical enclosed space 6. Here, the velocity of steam  and hot water flowing upward in the pipe 3 is controlled by the diameter of pipe 3 (process A). Then, reflux  flow of hot water is poured into the enclosed space 6 from a return pipe 18 (process C). As a process B in  addition to the process A, a pipe 13 formed with many connecting holes 15 in its side wall is inserted into the casing 12 until it reaches the well bottom 14, with its cylindrical space 16 being opened to the atmosphere, and  a reflux well 11 for carrying reflux flow of hot water back to the top of pipe 13 via a return pipe 18 is disposed  on the upstream side of the production well 11. As to the welling characteristics of the well, in case that a two- phase flow of steam and hot water of a consistant dryness is produced from the well, only the process A is  employed. On the other hand, in case that the dryness is increased and the content of steam is increased with  increase of the flow rate, processes A, B, C are employed simultaneously. Further, in case that only steam is  produced, processes B, C are employed.

Title: Wireless security system equipped with supervise function
Inventor: KIKUCHI MASAHIRO
IPC: G08B25/10
Filed: 1990-04-27
Abstract: PURPOSE:To monitor normally a security transmitter in suspension by providing a relay receiver at the keeping place for the security transmitter in suspension and connecting the relay receiver to each monitoring controller. CONSTITUTION:A periodic transmission signal to which a house code and an ID cord are attached is transmitted from a security transmitter 2 as a radio wave signal in each prescribed period. A relay receiver 3 provided at the keeping place receives the periodic transmission signal by an antenna 3a and transmits an amplified high-frequency signal to a signal line (l) if it is needed. A controller 1 receives the high-frequency signal transmitted through the signal line (l), and a receive processing part 16 demodulates the periodic transmission signal and transmits it to a signal processing part 10. The erroneous information from a supervise function is prevented because the periodic transmission signal can be received by the controller 1 only after the security transmitter 2 is moved to a keeping place K when it needs to be suspended.

Title: Light emitting diode device
Inventor: NISHI HIDEO
IPC: H05B45/50
Filed: 1982-06-30
Abstract: PURPOSE:To compensate the inoperative state of a light emitting diode to be emitted by operating instead other light emitting diode rapidly when the diode to be emitted is not operated by connecting light emitting diodes of different rising voltages or a light emitting diode chip electrically in parallel with each other. CONSTITUTION:A light emitting diode 1 fires at a terminal voltage between terminals (a) and (b) connected in parallel with each other normally at a voltage equal to or lower than 1.5 volt, and a forward current is set to a circuit which becomes a forward voltage that does not reach the rising voltage of the other light emitting diode 2 when this one diode 1 fires. When the forward current is set in this manner, a transistor 5 becomes On state by the application of an output signal from a light signal output unit 6 when the diode 1 is normal, and the diode 1 emits a light, while the other diode 2 does not emit a light at all. When the diode 1 becomes impossible to emit a light, the voltage between the terminals (a) and (b) rises, and the diode 2 emits a light thereby compensating the disconnection of the diode 1.
