IPC: C25D3/22
Filed: 1983-10-05
Abstract: PURPOSE:To obtain a galvanized steel sheet preventing a blackening phenomenon during storage by adding specified times as much Ni ions as Pb ions contained in a galvanizing bath to the bath, galvanizing a steel sheet in the bath, and chromating it. CONSTITUTION:To a galvanizing bath are added 5-500 times as much Ni ions as Pb ions contained in the bath as an impurity. The amount of Ni ions to be added is <=1/25 time the amount of Zn ions and <=10g/l. A steel sheet is galvanized in the electrolytic bath, and it is chromated in an aqueous soln. contg. Cr<+6> as the principal component. When a galvanized steel sheet obtd. by this method is stored in a piled state in a wet atmosphere at a high temp., the blackening phenomenon of the surface is remarkably reduced.

Title: Detection of off-track amount of magnetic head
Inventor: EZAKI TOMOHIRO
IPC: G11B21/10
Filed: 1984-09-07
Abstract: PURPOSE:To improve the detecting accuracy of the off-track amount and the reliability and the recording density with a magnetic head, by dividing the difference of amplitude between reproduction waveforms of a pair of servo signals by the amplitude value of the reproduction waveform of a signal having an even phase. CONSTITUTION:A synchronizing signal detecting circuit 11 produces pulses for a fixed period when an input signal (a) having a prescribed interval exists. A control signal (c) is produced 12 at the rise of said pulse. A peak holding circuit 13 holds the peak value of the signal (a) while the signal (c) is kept at H. Then the circuit 13 is reset when the signal (c) is changed to L, and the output of the circuit 13 is set at 0. In the same way, the sample holding circuits 14-16 sample the input signals by control signals (e), (f) and (g) and hold them. The difference of voltage is calculated 17 and divided 18 with the outputs of circuit 14-16, and the prescribed gain is added 19 to each of these outputs. Then a desired off-track amount is obtained, and a stepping motor 19 is controlled via a control circuit 20. Thus the position of a magnetic head 9 is corrected.

IPC: H01M50/541
Filed: 1982-10-22
Abstract: PURPOSE:To separate lead oxide from the surface and perform integration by collecting a number of plate lugs, positioning them in a jig, and heating and dissolving the plate lugs and a connecting body positioned in a dam using a gas burner with a large diameter flame hole and a small diameter flame hole for holding frame. CONSTITUTION:The lugs 1a of a number of plates 1 are collected in a body and guided to pass through the notch of a jig 2 for forming a rack and then protrude in a dam 3. A gas burner 10 forms a large diameter flame hole 10a that mainly performs heating fusion at the center of the tip of the burner and provides a number of small diameter flame holes 10a for holding flame at the position on the outside concentric circle. The burner 10 is retained by a burner holding tool 8, and connected to a crank 11 and a rod 12 to make swing motion. While letting the burner 10 fall and swing, the lugs 1a in the dam 3, the base of a connecting body 4, and additional lead pieces 5 are heated and fused by the flame ejected from the flame holes 10a. Such collected lugs 1a and the connecting body 4 can be integrated together by means of a short rack and thus lead oxide is separated. As a result, the rack with excellent mechanical strength and electrical resistance values can be obtained.

Abstract: PURPOSE:To obtain the titled paint which gives a coating film having excellent erosion resistance and gloss retention, by mixing a specified anti-caking agent with an aq. dispersion of a fine acrylic polymer particle, drying the mixture and mixing the resulting powder with a paint stock soln. CONSTITUTION:0.1-50pts.wt. (100pts.wt. particles B described below) anti-caking agent (A) (e.g. vinyltrichlorosilane or fluorododecanoic acid) which is water- soluble or water-dispersible and non-volatile and does not cause the caking of the particles B, is mixed with an aq. dispersion of fine acrylonitrile polymer particles (B) having a particle size of 1mu or below, and the mixture is dried to obtain an acrylonitrile polymer powder. 5-60pts.wt. (per 100pts.wt. non-volatile matter in paint stock soln.) said polymer powder is mixed with a paint stock soln. to produce a clear paint. According to this method, the surface of the particle B is coated with the agent A so that the particle B is not caked, but exists in the form of fine particle as such. Hence, even when the particle is mixed with a clear paint, transparent appearance can be kept and weather resistance can be improved by the particle B.

Title: Power-on system
Inventor: SATO SHINICHI
IPC: G06F1/26
Filed: 1996-07-17
Abstract: PROBLEM TO BE SOLVED: To prevent power supply facilities from being overloaded momentarily owing to the generation of a rush current by simple constitution when respective devices constituting the system are powered on at the same time. SOLUTION: After a main switch 3 is turned on, the devices 4-7 are powered after random times are elapsed. In this case, a timer in each device clocks a random time and a current value is measured after the clocking operation by the timer; if an excessive current flows, the operation for reclocking a random time is repeated to power on the device. Thus, the random time is clocked, so a wait time does not match that of another device and the generation of a rush current can be prevented with the simple constitution.

Title: Inflow level calculation system for dam
Inventor: MASAKA HIROYOSHI
IPC: G01F1/52
Filed: 1981-11-19
Abstract: PURPOSE:To calculate the inflow level at a high accuracy even when water level varies slowly by performing a specified calculation when the water level variation exceeds a specific value. CONSTITUTION:A water level variation detecting section 5 outputs a calculation demanding signal to an inflow level calculating section 2 when detecting the water level variation exceeding a specified value by monitoring the water level from a level gage 3. Then, the inflow level calculating section 2 calcurates the inflow level from the water level obtained from a difference between the current water level obtained from the level gage 3 and that observed when the previous variation occured in the water level and the discharge given by a discharge calculating section 4. In this manner, the calculation of the inflow level for a dam is performed each time the water level varies. This enables the calculation  of the inflow level with a high reliability and a good responsiveness regardless  of the speed of the water level variation.
