Title: Treatment of copper-containing waste water
Inventor: HINO EIJI
IPC: C02F1/62
Filed: 1983-06-21
Abstract: PURPOSE:To perform the inexpensive and stable treatment of waste water, by adding Ca(OH)2 to copper-containing waste water to precipitate and separate copper hydroxide while adding iron salt to the separated liquid to perform coprecipitation. CONSTITUTION:Ca(OH)2 is added to plating waste water or pickling waste water containing copper to precipitate copper as copper hydroxide and the precipitant is separated by using a high-molecular flocculant such as polyacrylamide. To this separated liquid, iron salt such as iron sulfate (II), iron sulfate (III), iron chloride (II) or iron chloride (III) is added in an amount of about 2mg/l or more as Fe to form iron hydroxide which is, in turn, coprecipitated along with copper hydroxide. By this method, the flocullation and dehydration properties of the precipitant are enhanced and stable copper removal can be performed in high removal efficiency.

Title: Method for rolling shape with flange
Inventor: HIROSE KAZUFUMI
IPC: B21B1/088
Filed: 1995-05-10
Abstract: PURPOSE: To enable a lot of rolling without being affected by roll wear and with the same rolls without changing rolls by taking rolling order in which the flange width of a material to be rolled is changed from a wide size to a narrow size in width and rolling every width with different parts of roll. CONSTITUTION: At the time of succeedingly rolling the narrow size after executing rolling of the material 4 to be rolled whose flange width is the max. size in width, the pass line 10 of a mill determined by the flange width of the material 4 to be rolled is made to approximately coincide with the pass line 12 of the material 4 to be rolled, a Δθ is made zero and rolling is executed so that the parts where the end parts of the flanges of the material 4 to be rolled are brought into contact with the side faces of horizontal rolls 1-1, 1-2 and the peripheral surfaces of vertical rolls 3 differ in every flange width. As the method for making the Δθ zero, the pass line 10 of the mill is vertically moved or the position 11 of the upside of a table is elevated and lowered. In this way, by dispersing the local wear parts of roll, the effect on the quality of a product is eliminated.

Title: Intersection guiding device
Inventor: TANADA SHOICHI
IPC: G06T11/60
Filed: 1996-05-02
Abstract: PROBLEM TO BE SOLVED: To provide an intersection guiding device which, in accordance with driver's familiarity with a to-be-guided intersection, guides a driver to the intersection in easy-understood manner. SOLUTION: While a to-be-guided intersection is related to an entrance rink, an intersection name or street names connected to each intersection and facility names at each intersection are stored in a disc. A rink corresponding to the trace which a car has traveled is stored in a non-volatile memory. When a car comes near a to-be-guided intersection, it is judged whether the entrance rink corresponding to the intersection is included in a travel trace data or not. If it is included, a guide information about the intersection is reported based on the proper name of intersection or the proper name of street connected. If an entrance rink is not included in the travel trace data, a guide information about the intersection is reported based general names of facilities at the intersection or a land marks representing facilities.

Title: Gate circuit for self-arc-extinction type semiconductor element
Inventor: ICHIKAWA KOSAKU
IPC: H03K17/732
Filed: 1994-05-26
Abstract: PURPOSE:To improve the reliability of the circuit by providing plural electrolytic capacitors in parallel with the gate circuit to monitor the discharge current of each capacitor thereby detecting a capacitor whose capacitance is lost indirectly and avoiding a sudden failure in turn-off. CONSTITUTION:In the gate circuit comprising a self-arc-extinction semiconductor element 1, when the gate circuit is in turn-off operation at a current less than a maximum interrupting current and any capacitor 3 whose capacitance is lost or opened is in existence in the capacitor group, a current of the capacitor 3 detected by current transformers 6a-6n is smaller than the current of the other normal capacitors 3. Since no signal is outputted from a comparator 7 receiving the current of the capacitor 3 whose capacitance is lost, a discrimination device 8 discriminates the defective capacitor. The discrimination device 8 makes discrimination while ranking faulty states depending on output states of plural comparators 7. Thus, the processing for issuing alarm and for conducting protection is ensured for the gate circuit in this way.

Title: Wired logic circuit for semiconductor integrated circuit
Inventor: USHIDA TOMIO
IPC: H01L21/822
Filed: 1988-05-11
Abstract: PURPOSE:To prevent the reduction in an input voltage from being caused even with WOR (wired OR) by providing a wire pattern connecting two output terminals or over sequentially in an emitter coupled logic(ECL) circuit and connecting a bias resistor to one terminal of the wire pattern. CONSTITUTION:A wire pattern 10S connecting to output terminals S1, S2, S3 of the ECL circuit is connected sequentially from the terminal S1 to S2 and from the terminal S2 to S3 and no branch point exists at all. A bias resistor TR is connected to one terminal S3 of the wiring pattern 10S and a partial net 3 comprising input terminals K1, K2 of the ECL circuit is connected to the other terminal S1 via a wire pattern 10K. Since the wiring pattern 10K connecting to the input terminals is connected in the vicinity of the output terminal connected finally by the wire pattern 10S when viewed from the bias resistor TR, only when the signal current flows from the output terminal connected finally, the effect of the voltage drop due to the signal current flowing to the wiring pattern between the connecting point and the output terminal is received slightly.

Title: Method and mechanism for operating buffer type gas-blast circuit-breaker
Inventor: TSUCHIKAWA MIYUKI
IPC: H01H33/34
Filed: 1995-05-11
Abstract: PURPOSE: To reduce the minimum quantity of the compressed gas, and to miniaturize a buffer chamber so as to miniaturize a device by temporarily stopping a movable arc contact when a fixed arc contact is drawn out from a nozzle hole of an insulated nozzle at the time of cutoff operation. CONSTITUTION: A truncated conical braking bodies 33, 34 are provided in the tip of a movable piston 32 inside of a hydraulic cylinder 31, and a narrow part 39 a little larger than the outer diameter of the braking bodies 33, 34 is provided inside of an oil pressure chamber 51 of the cylinder 31 so that the braking bodies 33, 34 achieve the narrow part 39 when a fixed arc contact is drawn out from a nozzle hole of an insulated nozzle at the time of cut-off operation. Since a clearance between the braking bodies 33, 34 and the narrow part 39 is narrowed, resistance is generated when the braking bodies 33, 34 passes through the part 39. Consequently, movement of the piston 32 is temporarily delayed and it can be stopped.  A large quantity of the compressed gas is blown out so as to extinguish the arc when the fixed arc contact is drawn out from the nozzle hole of the insulated nozzle, and an arc-extinguishing property is improved, and a necessary quantity of the compressed gas is reduced so as to miniaturize the device.

IPC: F24H1/00
Filed: 1987-05-08
Abstract: PURPOSE:To reduce a frequent ignition and a diminishing of fire of a burner unit by a method wherein a heating calorie of a burner unit is reduced more than that of hot water feeding time when only an additional heating is being performed. CONSTITUTION:A hot water feeder having an additional heating function is operated such that for example, water in a boiler 11 is heated by a burner unit 11 provided with a high combustion burner 12 of Hi and a low combustion burner 13 of Lo and then the heated water is utilized in a hot water feeding operation and at the same time water circulating between the boiler 1 and an external bath tub and the like is heated by the burner unit 11 to perform an additional heating. When only the additional heating is to be performed, only the burner 13 of Lo of the burner unit 11 is ignited and a heating capacity of the burner unit 11 is decreased and then it becomes equal to an additional heating capacity and so a frequent ignition and diminishing operation in the burner unit 11 is reduced.
