Title: Detector for battery state
Inventor: TANAKA AKIFUMI
IPC: G01R31/36
Filed: 1985-04-11
Abstract: PURPOSE:To grasp the accurate state of a storage battery by detecting the capacity of the storage battery from a voltage at the time of cracking, a voltage drop due to the load during a run, or no-load voltage. CONSTITUTION:The voltage when the storage battery is unloaded, the voltage during a run, the voltage at the time of cracking, and the capacity of the storage battery differ in constant of proportion, but has nearly linear proportional relation. The voltage of the storage battery is divided by the series resistance of resistances r1-r4 so that those three voltages become equivalent; and a point (a) is regarded as an in-cracking voltage detection point, a point (b) as a load voltage detection point, and a point (c) as a no-load voltage detection point. Further, a high resistance r6 is interposed between the no-load voltage detection point (c) and the input terminal of a linear IC 2 for turning on an LED and the no-load voltage is applied to the capacitor C at any time. If a voltage drop due to a decrease in the capacity occurs during a no-load state, run, or cracking, the capacitor C decreases the number of LEDs in a on state and the charge state of the storage battery is displayed as the charging voltage during the run rises.

Abstract: PROBLEM TO BE SOLVED: To make it difficult to illegally unlock a lock member by providing the lock member which is locked by providing a member engaged by hooking the loop part of a detection conductive wire while inserted into a case and is moved in an unlocking direction. SOLUTION: A wire is run thorugh a hole, etc., of an article and then the loop part 4a of the wire is passed through a cut engagement part 12 of an engagement member 5. Then the engagement member 5 is twisted downward and pressed in against the spring force of a coil spring 17. The engagement member 5 is slid downward and the loop part 4a in the notch engagement part 12 is moved to the inner side of the cut engagement part 12 since the upper edge of the cut engagement part 12 slants. Consequently, the loop part 4a hardly comes out of the cut engagement part 12 during the downward movement of the engagement member 5 and is securely engaged. Consequently, a contact piece operation part 23 of the engagement member 5 connects an upper contact 24 to a lower contact 25 of a power source switch 8, which is turned on.

Title: Formation of transparent conductive film
IPC: H01B13/00
Filed: 1992-03-31
Abstract: PURPOSE:To avoid difference in thickness by applying ultrasonic vibration to a nozzle to spray and whereby reducing the diameter of an atomized metal compound and homogenizing it for effective adhesion to the surface of a substrate to be adhered. CONSTITUTION:Ultrasonic energy is applied to a liquid metal compound 2 fed from an inlet port 8 to an atomized surface 9 by a piezoelectric device 10 to promote atomization. Effective atomization is achieved by designing the ultrasonic vibration so that the amplitude of the vibration reaches a maximum level at the atomized surface 9, and further grain refining and homogenization are achieved. A transparent conductive film in which difference in the thickness is drastically reduced, is thus formed. Since the grain refining with high atomization efficiency is achieved, the mass is reduced in relation to the momentum of the grain, and recoiling on the surface of a substrate to be adhered is small. Difference in the thickness is reduced thereby.

Abstract: PURPOSE:To reduce oxidation of a molten metal owing to air by inserting the bottom end of a ladle into an injection sleeve, charging a molten metal into the sleeve, and controlling the ladle by a sensor to move upward the ladle intermittently when the surface of the molten metal rises higher than the molten metal port of the ladle. CONSTITUTION:The bottom end of a ladle 18 contg. a prescribed amt. of a molten metal is inserted deeply into an injection sleeve 15 and a valve stem 30 is moved upward to discharge the molten metal through a molten metal port 31 into the sleeve 15. The ladle 18 is held still. When the surface of the molten metal in the sleeve 15 rises higher than the position of the port 31 and contacts a sensor A and contacts further a sensor B upon rising, the ladle 18 is quickly moved upward by a ladle conveyor. When the surface of the molten metal falls lower than the sensor A, the ladle 18 is held still and when the molten metal surface rises again to come into contact with the sensor B, the ladle 18 is moved upward. The ladle 18 is thus moved upward intermittently by the sensors A, B so that the molten metal is successively discharged into the sleeve 15. The contact of the molten metal with air is thus reduced and the intrusion of the air therein is prevented.
