IPC: G01R31/18
Filed: 1985-05-27
Abstract: PURPOSE:To elevate the inspection efficiency while conserving labor for changeover of an inspection head, by moving a plurality of inspection heads arranged in a row to switching over the inspection head used. CONSTITUTION:Five head support platforms 2 are arranged in a row and moved with a pulse motor 9 through a timing belt 10. The support platforms 2 are each provided with a head support device 3 in such a manner as to be movable vertically with an air cylinder 4 and an inspection head 7 having the required number of inspection probes 8 is supported downward thereon 3. Then, as a printed circuit board 12 is fed under the support platform 2 on a belt conveyer 11, a sensor 13 detects it and a positioning mechanism 14 is actuated to position the circuit board 12 at the specified position. Then, the support platform 2 is moved with the motor 9 to place a desired inspection head 7 at the inspection position and the inspection head 7 is lowered to contact the circuit board 12 for inspection. In such a manner, the premounting of five types of inspection heads 7 facilitates the changeover of the inspection heads 7 by the operation of the motor 9.

Title: Charging method for storage battery
Inventor: NISHIKAWA KEIZO
IPC: H02J7/10
Filed: 1991-04-18
Abstract: PURPOSE:To prevent a storage battery from being overcharged even when the storage battery does not discharge electricity much. CONSTITUTION:Strong charging control is switched to weak charging control when the terminal voltage V of storage battery reaches a gas generating voltage Ve. The weak charging time Tk is counted until the variation V of the terminal voltage V per unit time becomes lower than a prescribed fully-charged state discriminating value Vs from the start of weak charging and the charging time is changed in accordance with the duration of the weak charging time Tk. Since the weak charging time is changed by utilizing such a characteristic that the weak charging time Tk varies depending on the discharging state of the battery, no overcharging nor insufficient charging occurs and the service life of the battery is not shortened.

Title: Covered electrode for hardening and building-up
Inventor: HATSUTORI NAOJI
IPC: B23K35/365
Filed: 1980-08-20
Abstract: PURPOSE: To suppress the variance in the hardness of deposited metal and improve the quality of a covered electrode for hard facing by controlling ≥50wt% C in a covering material by the combination use of iron alloy powder specified of the content of C and of grain size and metallic carbide or the use of either of these alone.  
     CONSTITUTION: In a covering material to be coated on the outside circumference of a steel core contg. ≤0.15% C by weight, ≤50wt% C in the covering material is controlled by iron alloy powder contg. ≥1.1% C by weight or the iron alloy powder and metallic carbide. At this time, the one of 10W210μ grain size constitution in the 50% value of the cumulative weight grain size distribution curve of the iron alloy powder or metallic carbide is used. The content of the C in the covering material is set at 1.2W15% by weight. If the content of the C in the core is increased, drawing workability degrades and if the content of the C in the covering material is out of the limited range, it is not possible to impart sufficient stregth. The reason for specifying the content of the C in the iron alloy powder lies in that if it is below the limits the hardness will be unstable.
