Abstract: PROBLEM TO BE SOLVED: To provide a radio receiver and an automatic tuning method which tunes in to only a broadcast station that has a good receiving quality without adjacent channel interference, etc., at the time of a seek operation. SOLUTION: At the time of a seek operation, an SD signal (station detector signal) detecting part 25 checks an SD signal and when the SD signal is '1', the part 25 executes adjacent channel interference signal detection processing, an SD chattering detection processing and IF count processing (count of an intermediate frequency signal). The adjacent interference signal detection processing is performed when an adjacent interference detecting part 26 detects a 100k beat signal and the SD chattering detection processing is performed when the part 25 checks the state of an SD signal in every prescribed time. Also, the IF count processing is performed when an IF detecting part 24 counts an intermediate frequency signal.  Through these processing, the seek operation is stopped when there is no chattering of the adjacent interference and the SD signal and when it is decided that a prescribed frequency signal is received.

IPC: B61L23/14
Filed: 1978-02-10
Abstract: PURPOSE: To prevent a train from becoming impossible to run though it does not approach other train by displacing the travel instruction signal communicating means from the train position detector in operating regions in a train controller adapted for an in-station carriage or the like.  
     CONSTITUTION: If a following train enters into a section B when a train 23 is located in a section A, a relay 6 for detecting the train 23 in the section A opens a circuit for producing run instruction imparged from a ground controller to run instruction trolley wire 12 in the section B to thereby stop the following train. In a train controller for thus preventing the train from colliding with the other train, the insulator 25 of a train position detecting trolley wire is displaced from the insulator 25 of a run instruction trolley wire at a distance L longer than the interval l between the brushes 21 and 22 of a current collector in the travelling direction of the train. Thus, run signal communicating current collecting brushes 26, 27 make previously contact with next section to thereby prevent the train from becoming impossible to run.

Title: Solar heat collecting device
Inventor: MIYANARI MASAHARU
IPC: F24D11/00
Filed: 1983-01-31
Abstract: PURPOSE:To increase the heat collecting efficiency of the titled device by a method wherein the heat transfer between hot water supplied from a heat collector and a latent heat storage material liquefied at its melting point is made through a watertight shell in a liquid-liquid phase relationship so that the amount of heat transfer is increased as compared to the amount of heat transfer between the two in a solid-liquid phase relationship and water in a heat storage tank is heated by latent heat generating when the phase of the latent heat storage material changes from liquid to solid. CONSTITUTION:The hot water stored in the heat storage tank 2 transfers heat to the latent heat storage material 7 in a heat accumulator 4 comprising the watertight shell 5 having the heat storage material 7 sealed therein and when the melting point of the heat storage material 7 is reached, the phase of the material 7 changes from solid to liquid so that the material 7 is sealed in liquid phase within a hollow section of the watertight shell 5. In this case, when the hot water is collected by a hot water collecting pipe 10 while water is supplied from a water supply pipe 11 to the heat storage tank 2, the supplied low temperature water is heated by the latent heat discharged from the latent heat storage material 7 constituting the heat accumulator 2 when the phase of the material 7 changes from liquid to solid.

Title: Turbine type flowmeter
Inventor: MORITA HIROSHI
IPC: F16C39/00
Filed: 1984-01-30
Abstract: PURPOSE:To expand the measuring range of a flowmeter and to omit maintenance, by supporting a turbine rotor by the different modes at the time of a low flow rate and at the time of a high flow rate. CONSTITUTION:Most of a thrust force, which is received by a rotor 9 from a flow, is received by a dynamic-pressure bearing part 14. Only a force, which merely keeps the rotary axial center of the rotor 9 at the axial center of a pivot shaft 6, acts on the pivot shaft 6. Therefore, friction between an upper end pivot part 6b of the pivot shaft 6 and a pivot bearing 12 of the rotor 9 is small, and abrasion is prevented. At the time of low flow rate, the pivot bearing 12 is supported by the pivot shaft 6 in a one-point supporting mode and the rotary friction is small. Therefore the rotor 9 can be rotated with high sensitivity against the minute amount of the flow. At the time of a high flow rate, the bearing 12 is supported by a dynamic-pressure bearing part 14 effectively without the mechanical friction. Therefore, the rotor can well respond to the large flow rate and can be rotated. Thus the range of the flowmeter can be expanded. The mechanical friction of the pivot bearing part 13 and the dynamic-pressure bearing part 14 is small, and maintenance is hardly necessary.
