Title: Stabilization of mannich reaction product of polyacrylamide
Inventor: IKEDA HIROSHI
IPC: C08F20/00
Filed: 1980-08-05
Abstract: PURPOSE: To stabilize a Mannich reaction product of polyacrylamide in an acidic state, by adjusting the pH of an aqueous solution of the product to a specified range.  
     CONSTITUTION: The pH of an aqueous solution of a Mannich reaction product of polyacrylamide is adjusted to below 2.5. In this way, merely by adjusting the pH in the above range without adding any stabilizer, the product can be prevented from crosslinking, with a consequent increase in the number of days elapsed till gelation, and can remain long in an aqueous solution state. The acids which can be used include mineral acids such as sulfuric acid, hydrogen sulfate salts, sulfamic acids and hydrochloric acid. Organic acids such as acetic acid and lactic acid can not be used. The polyacrylamide concentration of the above aqueous solution is 2W20% and is selected taking account of miscibility, solubility, MW, transportation cost and the like.

IPC: H01L23/12
Filed: 1988-04-30
Abstract: PURPOSE:To make thick a solder-plated film on lead pins and to contrive the improvement of the aging resistance of the lead pins by a method wherein the lead pins are dipped in a molten solder bath in a state that the lead pins are inserted in the through holes of a jig plate and thereafter, a board for mounting electronic components is raised in the almost vertical direction as the jig plate is left on the molten solder bath. CONSTITUTION:In case the periphery of an electronic component mounting part 3 and lead pins 4 are bonded together in solder joint and at the same time, a solder- plated layer is formed on the pins 4, a jig plate 6 having through holes 61, in which the pins 4 are inserted, is used and after the pins 4 and board 1 for mounting electronic components are dipped in a molten solder bath 7, the board 1 only is raised in the almost vertical direction as the plate 6 is left on the bath 7. Accordingly, as a heating of the substrate due to a fused solder is interrupted by the jig plate, heat dissipation from the surfaces of the pins 4 and so on is comparatively quickened after the board 1 is raised from the bath 7 and the film thickness of the solder-plated layer on the pins 4 becomes thick. Thereby, the film thickness of the solder-plated layer on the surfaces of the lead pins is uniform and thick and the aging resistance of the lead pins is improved.

Title: Duty correcting circuit
Inventor: HIROSE KAZUTO
IPC: H03K5/04
Filed: 1981-07-15
Abstract: PURPOSE:To easily reproduce an accurate 50% duty waveform, by using a delay circuit, an FF circuit, and a differentiating circuit in combination. CONSTITUTION:An input signal (a) with a period T supplied from an input terminal 1 has been differentiated of rise by a differentiating circuit 7 to obtain a differential output (b). This differential output (b) sets a D type FF circuit 6 directly. The input signal (a) is further supplied to a delay circuit 3, where it is delayed accurately by T/2 to obtain a delay output (c). Then, a rising edge of this delay output (c) resets the FF circuit 6. Therefore, the circuit 6 is set and reset repeatedly, so that the FF circuit 6 outputs a 50% duty rectangular wave, which has the same frequency with the input signal (a) to an output terminal 5. Thus, the accurate 50% duty waveform is reproduced easily.
