Title: Method for adjusting electroplating bath
Inventor: NONAKA TADASHI
IPC: C25D21/14
Filed: 1989-11-15
Abstract: PURPOSE:To accurately control the Na2SO4 concn. in the electroplating bath at all times and to improve efficiency in using plating power by measuring the metallic ion concn., sulfate ion concn. and pH in the bath acidified with sulfuric acid and obtaining the Na2SO4 concn. in the bath from the values. CONSTITUTION:The surface of a material is electroplated with metal using a metal plating bath acidified with sulfuric acid. In this case, since the electric resistance of the bath is reduced by the Na2SO4 in the bath and hence the consumption of the plating power is reduced, a specified amt. of Na2SO4 is kept in the bath at all times. The concns. of the ions of the metals such as Ni, Zn and Fe in the bath 11 in operation are measured by a fluorescent X-ray analyzer 4, the pH of the bath by a pH meter 12 and the Fe<3+> ion concn. by an absorptiometer 5, the pH is corrected by the temp. of the bath measured by a thermometer 3, and the Na ion concn. in the bath 1 is obtained from the measured values. The Na2SO4 concn. is obtained from the Na ion concn., Na2SO4 is replenished in the amt. corresponding to the consumption to keep the control value, hence the electric resistance of the bath is always kept low, and the plating power is reduced.

IPC: B65B55/06
Filed: 1996-10-18
Abstract: PROBLEM TO BE SOLVED: To keep variation in the temperature of cold heat small, and effectively utilize the heat by a method wherein a discharged hot waste water is utilized as a heat source water for an absorption type or adsorption type refrigerator, and a cooling water which is obtained from the cooling side of the adsorption type refrigerator, etc., is circulated from the downstream side to the upstream side. SOLUTION: The waste heat of a hot drain water which is discharged from an inlet side tank part of a continuous type cooler 10, is introduced to a heat source water side A of an adsorption type refrigerator 11a through a heating unit 12, and drives the adsorption type refrigerator 11a. On the cooling side B of the refrigerator 11a, a cooling water which is temperature-controlled to a specified temperature, is generated, and introduced to the downstream side of the continuous type cooler 10. The upstream side and the downstream side of the continuous type cooler form a thermally closed cycle through the adsorption type refrigerator 11a.  A cooling tower 30a forms an outside circulation passage of the cooling water between a next stage upstream side tank and a downstream side forward tank of the continuous type cooler 10, and decreases the temperature of the cooling water by an atmospheric radiation, and as a result, by making the hot waste water a heat source, required power is reduced, and an effective utilization of heat can be efficiently performed by a cooling water of a high precision.

Title: Device for inserting bare fiber to ferrule
Inventor: HIGUCHI KAZUHIRO
IPC: G02B6/36
Filed: 1987-11-26
Abstract: PURPOSE:To prevent the failure of a bare optical fiber by disposing a sensor which detects the retreat position of a ferrule chuck to the prescribed point behind the ferrule chuck. CONSTITUTION:The limit switch 5 sensor is disposed on a base plate behind the ferrule chuck 3 and further, a stopper 6 is disposed behind the same. The bare optical fiber 1 is inserted into a small-diameter hole 30 of a ferrule 2. The bare optical fiber 1 is forced into said hole while the fiber 1 is kept rotated when the front end of the fiber 1 abuts against the inlet wall 20 of the small- diameter hole; therefore, the ferrule chuck 3 is retreated to trip the limit switch 5. The retreat position is thus detected. The forcing in of the fiber 1 is ceased when the retreat position is detected. The state before the forcing in of the fiber 1 is then restored and the insertion operation is repeated. The forcing in of the fiber into the ferrule beyond the retreat position is thereby prevented and the bare optical fiber is easily inserted with the ferrule without breaking the fiber.

Abstract: PURPOSE:To suppress abnormality of low order higher harmonic by feeding basic wave voltage component in the output voltage from an active filter necessary for system interconnection from the upper system of a bus through a transformer and producing only compensating basic wave voltage and higher harmonic compensated voltage from the active filter. CONSTITUTION:An auxiliary transformer 7 is connected with a power source 4 located in the upstream of a transformer 5 which is located in the upstream of a bus 6, where one end at the secondary of the auxiliary transformer 7 is connected with one side winding of a coupling transformer 8 for an inverter 12 constituting an active filter 3. Basic wave voltage is fed from the power source 4 through the auxiliary transformer 7 then the inverter 12 laps a higher harmonic voltage over the basic wave voltage through the coupling transformer 8 and interconnects the overlapped voltage to the system bus 6. A higher harmonic current detector 10 takes outs a higher harmonic close to secondary higher harmonic, for example, and a control circuit 11 performs conduction control of the inverter 12 element thus producing a higher harmonic compensated voltage. By such arrangement, abnormal low order higher harmonic can be suppressed.
