Filed: 1996-03-29
Abstract: PROBLEM TO BE SOLVED: To inform a user of the approach of running down of a battery securely by controlling a controller which opens and closes a solenoid valve provided in a supply pipe of water and hot water to a discharge port in such a manner that it performs the control which is different from ordinary discharge situation when a voltage of the battery drops down to a certain value. SOLUTION: A solenoid valve 3 for water and a solenoid valve 4 for hot water which use a battery 8a as a power source are provided in a water supply pipe 5a and a hot water supply pipe 5b to a discharge port 5, and opening and closing of stop cocks 1a and 2a are controlled by a controller 7. Usually, the controller 7 controls in such a manner that the stop cocks 1a, 2a are opened when a user kicks a foot switch 6 at first to discharge water and the discharge of water is stopped when the user kicks the foot switch 6 next. When a voltage of a battery 8a drops down to a certain value, the controller 7 performs the control which is different from usual water discharge situation in such a manner that only the opening operation is done by the solenoid valves 3, 4 when the user kicks the foot switch and the closing operation is done after a certain period of time elapses. Consequently, the user can recognize that the battery is running down soon securely.

Title: Electronic component
Inventor: KOMORI CHIAKI
IPC: H01L33/62
Filed: 1996-03-29
Abstract: PROBLEM TO BE SOLVED: To prevent contact failure by limiting the movement of a connection part of electronic components. SOLUTION: A pair of leads 80, 82 of a light-emitting diode LED are connected by a wire 84, and this connection part is fixed by a fixed portion 86 made of resin. A stopper substrate 10 for limiting the movement of the leads 80, 82 on the connection part is provided. After the leads 80, 82 are bent, he leads are passed through a heating furnace for hardening an adhesive and then immersed with a molten solder. The movement of the connection part in this case is limited by the stopper substrate 10. That is, a residual stress is caused to act by the bending of the leads 80, 82. When the fixed portion 86 made of resin is heated in this state, the leads 80, 82 are moved in the bending direction by the residual stress and therefore the connection of the connection part might be separated. However, since the movement of the connection part is limited by the stopper substrate 10, contact failure of the connection part is prevented and failure in lighting of the light-emitting diode is reduced.

Abstract: PURPOSE:To increase the inversion speed of a transistor and reduce the switching loss, by forming a trigger signal to turn off the transistor on the basis of the voltage whose phase is behind that of the voltage between the collector and the emitter of a transistor in a blocking oscillating circuit. CONSTITUTION:At the connecting point x between a capacitor 28 and a resistor 29 connected in parallel to the primary winding 22a of a transformer 22, a voltage whose phase is behind that of the voltage between the collector and the emitter of a transistor Tr 23 is generated. Said voltage is inverted, amplified 36 and compared with a reference voltage 37 in a voltage-comparing circuit 35.

Consequently, the base current Ib1 of the transistor Tr 23 flows in the direction opposite to the direction therefore, so that the transistor Tr 23 is turned off in a moment. In addition, when the positive output of the circuir 35 no more exists, the transistor 26 is turned off, and the transistor Tr 23 is turned off. When a capacitor 24 has finished a discharge, the transistor Tr 23 is turned on again.

Title: Abnormality detecting method of temperature controller
Inventor: FURUKAWA NOBORU
IPC: G03G15/20
Filed: 1983-05-04
Abstract: PURPOSE:To judge the abnormality of a temperature controller accurately even when a detecting element having high specific-value temperature dependency is used by judging the abnormality after heating or cooling a body to be detected. CONSTITUTION:A control signal ENPOWER for heating the device 1 to be detected is inputted firstly to heat the device 1 to be detected, and the output of the detecting element 2 enters a linear region. When the device is heated up to a specific temperature, a comparator 5 outputs 0, and a gate 7 outputs 0 and a switch circuit turns off to cut off power supply to the device to be detected. Although the element has high specific-value temperature dependency, the judgement of real abnormality is made as far as an output of high-temperature abnormality or heat breaking down is outputted from comparators 3 and 4 when a signal ENERROR is inputted to a gate 9, thereby outputting a signal ERROR. The judgement is made after the temperature of the device 1 to be detected is raised above the specific value, but may be made after the device is cooled.

Title: Error correction method
Inventor: SAKO YOICHIRO
IPC: H03M13/27
Filed: 1987-03-31
Abstract: PURPOSE:To prevent the deterioration the burst error correction length by expanding the final interleave interval of the P series and reversing the direction of retarding the interleave so as to locate the final word of the Q series after the preceding word. CONSTITUTION:The final interleave interval of the P series is expanded as to the P and Q series with respect to an optional word and the interleaving is applied to restore a word W7 and the Q series in reverse direction so as to locate the final word of the Q series after the recording word. Thus, even if an error exceeding the correctable burst error length takes place, the remaining error is reduced. Moreover, in order to improve the error correction capability at the simultaneous occurrence of a burst error and a random error, it is preferred to take the largest interleave delay quantity (quantity of restoration) in the reverse direction. Thus, the deterioration in the burst error correction capability is prevented and the deterioration in general error correction capability is prevented.
