Filed: 1979-04-10
Abstract: PURPOSE: To remelt excessive solder without damaging a print wiring board plated with solder and a circuit by a method wherein the wiring board is preliminarily heated, steeped in a heating liquid and annealed.  
     CONSTITUTION: A print wiring board manufactured by plating an upper portion of a print circuit with solder is preliminarily heated in order to avoid a sudden temperature change in case of melting. The wiring board is steeped in a liquid with the high boiling point such as silicon oil, etc. to remove excessive whisker-shaped solder. The board is annealed in circulating air at room temperature, further washed by water at the normal temperature to remove the liquid with the high boiling point, which remains and adheres, and lastly heated according to an air circulation system to remove residual moisture. According to this method, all of the failure and abnormality of the print circuit and the discoloration and the abnormality of the external appearance of the print substrate are removed.

Abstract: PURPOSE:To attain stable synchronization even when a frequency divider is operated intermittently by using a means value in response to a leading time difference of an output signal within the operating period of the frequency divider frequency-dividing an output signal of a VCO so as to control the generated frequency from the VCO.

Title: Universal joint
Inventor: UCHIDA SUSUMU
IPC: F16D3/20
Filed: 1987-02-27
Abstract: PURPOSE:To suppress deterioration of grease by filling an enclosed space for encapsulating grease for lubricating a coupling body with nitrogen gas, thereby preventing breakdown of a flexible boot due to deformation of the enclosed space caused through droppage of inner pressure. CONSTITUTION:An enclosed space 7 for encapsulating grease for lubricating a coupling body 5 is filled with nitrogen gas. Consequently, even if a universal joint repeats operation/stoppage and the temperature of the coupling rises/lowers repeatedly, nitrogen gas scarcely escapes from the enclosed space 7 through a flexible boot 6 to the outside as shown by an arrow (a). Furthermore, since nitrogen gas is scarcely absorbed by the material of boot 6, remarkable pressure drop does not occur in the enclosed space 7 nor the bellows section collapses radially inward as shown by a dashed line 6a', thereby damage of the flexible boot 6 due to collapse can be prevented. Furthermore, deterioration of grease due to nitrogen is suppressed.
