Title: Copper pyrophosphate plating bath
Inventor: MINAGAWA TADASHI
IPC: C25D3/38
Filed: 1979-04-13
Abstract: PURPOSE: To form a copper-plated film superior in ductility and smoothness with an excellent uniform electrodeposition at high cathodic current density, by a method wherein potassium phosphate and ammonia in specified concentrations are added in a copper pyrophosphate plating bath.  
     CONSTITUTION: Potassium phosphate in 20W60g/l concentration as orthophosphoric acid ions and ammonia in 1.3W2.5g/l concentration are added in a copper plating bath, whose principal ingredients are copper pyrophosphate and potassium pyrophosphate. A uniform electrodepositing property is improved by the copper pyrophosphate plating bath composition, and through-holes of a substrate for a printed circuit board are excellently plated. A tendency of decrease in glossiness of a plated film taking place in case of plating at a high cathodic current density is compensated by ammonia. At the same time, brittle plating is suppressed by the effect of the orthophosphate buffer, and the plated film with large elongation is obtained.

Title: Burner flame detecting device
Inventor: IKEUCHI TAKAYUKI
IPC: F23N5/12
Filed: 1986-02-28
Abstract: PURPOSE:To make it possible to easily discriminate a cause of flame failure and to carry out repair and adjustment in a short period of time by providing a switching device using an ignition portion as a detecting portion and switching it to a switching device to a flame detector for detecting the presence or absence of flame during combustion. CONSTITUTION:When a flame failure occurs during combustion, restarting of the detecting device is carried out to seek for the cause for the failure. However, when the restarting of the device is carried out, the voltage of an igniter 1 is slowly increased, and an ejected fuel is ignited at the igniting portion 2 of the igniter 1. If the voltage at the time of ignition is less than a predetermined value, the clearance at the igniting portion is normal, and the combustion flame is detected, whereupon it is possible to determine that the failure occurs due to causes other than the fault of the igniter 1, such as an excessive quantity of combustion air and the like. When the voltage value at the time of the failure is more than a predetermined value, it is detected that the clearance at the igniting portion 2 of the igniter 1 is extraordinary. Therefore, it is determined to be a flame failure because the combustion flame is not detected.

Title: Method and device for discriminating disk
Inventor: HASEGAWA YUICHI
IPC: G11B19/12
Filed: 1998-02-10
Abstract: PROBLEM TO BE SOLVED: To discriminate a kind of a disk in a short time without being affected by a scratch and dust on the disk surface, a wobbly surface, reflectance dispersion between disks or fluctuation in an optical light quantity, etc. SOLUTION: This device is constituted so that a state of a light spot on a photodetector is changed according to a relation between a design value of an objective lens and disk thickness. When the disk thickness is different from the design value of the objective lens, a peak level of a focus error signal is reduced compared with the normal case when the disk thickness coincides with the design value of the objective lens (refer to (A) and (D)). On the other hand, the peak level of the sum total signal isn't changed according to the disk thickness (refer to (B) and (E)). Thus, by comparing a ratio between focus error signal amplitude FA and sum total signal amplitude QA with a predetermined threshold value, the disk thickness is discriminated.

On the other hand, when it is detected by the circuit 10 that the voltage value of the battery 6 is returned to the prescribed voltage level or above, the comparator 7 is turned off.
