Title: Electroless copper plating method
Inventor: YAMANOI KIYOSHI
IPC: C23C18/40
Filed: 1988-11-22
Abstract: PURPOSE:To prolong the service life of an electroless Cu plating liquid which does not contain CN<-> ions by increasing the concn. of the dissolved oxygen in the plating liquid with an increase in the concn. of the by-product of reaction in the plating liquid at the time of executing Cu plating with the above- mentioned plating liquid. CONSTITUTION:A stainless steel sheet or the like which is subjected to a plating catalyst treatment on the surface is immersed into the electroless Cu plating liquid which does not contain the CN<-> ions and contains alpha,alpha'-dipyridyl and polyoxyethylene ether to electrolytically deposit the Cu on the surface and to form the thin film Cu plating. The accumulation quantity of Ne2SO4, HCOONa, etc., as the by-product by the plating reaction increases to degrade the activity of the electroless Cu plating liquid in this case and, therefore, a gaseous mixture composed of air and oxygen is permeated into the plating liquid to increase the concn. of the dissolved oxygen in the plating liquid, by which the stability of the plating liquid is maintained and the bright Cu electroless plating film is formed over a long period of time.

Title: Display and advertisement device switchable between continuous rotation and intermittent rotation
Inventor: OWADA CHIYOJI
IPC: G09F19/02
Filed: 1998-10-02
Abstract: PROBLEM TO BE SOLVED: To obtain a display and advertisement device adopting such a rotation system that improves a continuously rotating display and advertisement device not to be too simple, makes display contents easily visible and arouses general attention. SOLUTION: At both ends of the continuously or intermittently rotating display and advertisement device where the revolving shaft 2 moves for a prescribed section in the axial direction of rotation, a main spur gear 1 integral with this revolving shaft 2 is meshed with either of a sub-spur gear 4 and tooth lacked gear 5 respectively arranged in juxtaposition integrally on the other revolving shaft. A desired rotating speed is transmitted to the sub-spur gear 4 via a rotating speed adjusting means from a motor 8, by which a rotary disk 7 for display and advertisement matter connection may be connected to the front end of the revolving shaft 2 of the main spur gear 1.  If the revolving shaft 2 of the main spur gear 1 is set in a perpendicular direction, the main spur gear 1 may be moved together with the revolving shaft 2 by the vertical inversion of the main body and, therefore, the changeover of the continuous or intermittent rotation is made easy. Only the intermittent rotation can be obtained if the moving mechanism of the revolving shaft 2 is eliminated and the device is so constituted that the main spur gear 1 meshes with the tooth lacked gear 5 at all times in the constitution described above.

IPC: H04B1/74
Filed: 1985-12-27
Abstract: PURPOSE:To recover a line fault and to improve the reliability by allowing a time division multiplex communication equipment (TDMA equipment) to specify a fault of a low noise amplifier and a frequency converter and outputting a redundancy system changeover execution command from the TDMA equipment to the said equipment. CONSTITUTION:Since all bursts received by the TDMA equipment pass through a single output of a low noise amplifier, when the equipment is faulty, the output signal 7 is all faulty and as to all bursts received by the TDMA equipment, they are reflected as fault reception state (BNP) status. When the active TDMA equipment detects the fault, a redundant system changeover execution command signal 9 is outputted to the low noise amplifier and the redundancy system changeover is executed. After the execution of the changeover, a normal reception state (BP)/BNP status is collected again as to the all bursts and the recovery of the line is confirmed by detecting the state change from the BNP to the BP status. Further, the fault of a frequency converter is specified by the BP/BNP status of the burt received by the active system TDMA equipment.
