IPC: H01M8/04
Filed: 1983-05-18
Abstract: PURPOSE:To prevent any freezing of phophoric acid without using an installation box by installing a heater for heating a phosphoric acid-type fuel cell outside the fuel cell. CONSTITUTION:An electric heater 6 is installed adjacent to a fuel cell 5 and under the internal area of a sealed case 1.

Title: Detecting method for position of moving body on inductive radio system
Inventor: ARAI KIYOUICHI
IPC: G01D5/243
Filed: 1978-07-17
Abstract: PURPOSE: To make accurate position detection possible by shifting the intersection of main cross parallel lines from that of position correcting cross parallel lines at different angles when detecting the relative position of a moving body by a relative address system.  
     CONSTITUTION: Main cross parallel lines 10 and position correcting cross parallel lines 12 excited at different frequencies are provided on the track of a moving body. Lines 10 have intersections 10a at intervals of short period P and lines 12 have intersections 12a of long period P' shifting from intersections 10a by interval (α). Antennas 14 and 15 on the moving body receive 90°-out-of-position signals 16a and 18a from lines 10 and out-of-phase signals 16b and 18b from lines 12 at an extremely-small angle, and those received signals are processed to make position detection. In this way, since intersection 12a of lines 12 shifts in angle from intersection 10a of lines 10 at every correction point, detector 32 detects the angle of a position-detecting angle signal when the angle of the position-correcting angle signal is zero, i.e. the correction point.

Title: Combustion device
Inventor: ASANO YOSHIO
IPC: F23N5/20
Filed: 1981-06-03
Abstract: PURPOSE:To secure safety as well as to adjust temperature in the titled device by a method wherein abnormal states in combustion such as shortage of oxygen or the like are detected by a temperature detecting element installed for adjusting the temperature in a chamber through the output difference between said element and a blowoff side temperature element. CONSTITUTION:When the temperature difference between two temperature detecting elements 25, 26 does not exceed the designated value before a given period of time passes in a timer circuit, the solenoid is turned OFF and the fire is put out or non-firing can be detected because the output of a comparator 40 is high. When the temperature difference exceeds the designated value before a given period of time passes in a timer circuit, combustion continues because the output of the comparator 40 is low. The output of the comparator 40 becomes high also when the temperature difference does not exceed the designated value on account of incomplete combustion or the like during combustion and therefore the solenoid 6 can be turned OFF to put out the fire. Accordingly not only the temperature can be adjusted but safety also can be secured. This device is economically profitable and improved in reliability.

Filed: 1998-03-31
Abstract: PROBLEM TO BE SOLVED: To provide a circular fluorescent lamp having stem structure for preventing the contact of a mercury releasing alloy with an electrode part and capable of preventing damages of the outer appearance of a lamp, such as color change of a bulb in the circular fluorescent lamp into which a pellet-shaped mercury releasing allow is sealed, and provide a luminaire using this circular fluorescent lamp. SOLUTION: A flare stem 2 having lead wires 4, 4, an electrode 5, and an vacuum pipe 3 is sealed to both ends of an annular glass tube bulb 1 on inner surface of which a phosphor film is formed, a discharge medium containing a pellet-shaped mercury releasing alloy 7 is sealed inside, and an vacuum pipe opening part 3A of the flare stem 2 is directed toward the annular inward side of the glass tuber bulb 1. The pellet-shaped mercury releasing alloy released from the vacuum pipe opening part drops in a part not exceeding the electrode without colliding against the electrode and bulb inner wall (the phosphor film) since the distance between the bulb inner wall and the opening part is widened, and reaches the lower part far from the electrode. Since the collision of the mercury releasing alloy against the electrode is prevented, color changes clue to the vaporization of base body metal is not generated in the bulb inner wall (the phosphor film).
