Title: 6-cycle heat insulating engine and operating method thereof
Inventor: KAWAMURA HIDEO
IPC: F02B75/02
Filed: 1989-04-03
Abstract: PURPOSE:To improve cylinder inner wall surface cooling efficiency in a cold suction stroke and a cold exhaust stroke by providing a compression means to perform compression for a given period by means of a second exhaust stroke starting signal and an exhaust means to perform exhaust after elapse of a given period. CONSTITUTION:When it is detected by a rotation sensor 91 that a control unit 20 completes an exhaust stroke, while a piston 12 positioned in the vicinity of a top dead center is lowered to the vicinity of a bottom dead enter during a cold suction stroke, a suction port is opened by means of a suction valve device 7 to suck cold temperature air through an intake air line 71 to a cylinder 10. Further, after transfer of an engine from a cold suction stroke to a cold exhaust stroke, given suction and exhaust ports are closed to seal air in the cylinder 10. After elapse of a given period, at least the one of the suction and exhaust ports is opened to exhaust internal air. This constitution increases a time of contact between internal air and the inner wall surface of the cylinder 10 to perform transmission of heat, resulting in promotion of cooling of the inner wall surface of the cylinder 10.

Title: Solder dissolving solution
Inventor: YOSHIDA HIROSHI
IPC: B01J23/44
Filed: 1996-04-08
Abstract: PROBLEM TO BE SOLVED: To dissolve only solder, lead, tin and/or their alloys on a substrate without dissolving copper, copper alloy, etc., used as a substrate material by using as the dissolving solution, a hydrochloric acid solution contg. at least one metal selected from nickel, palladium and platinum as an active metal in an amount adequate to use the metal as a catalyst for the dissolution. SOLUTION: Since hydrochloric acid does not dissolve copper used as a substrate material at ordinary temp., the acid is appropriately used as an essential component of this dissolving solution for dissolving solder on a substrate, preferably in an amount sufficient to provide a 10 to 12mol/l concn. in the solution. When the hydrochloric acid concn. is <10mol/l, a long period of time is required to dissolve solder and on the other hand, when the hydrochloric acid concn. is >12mol/l, preparation of the solution becomes difficult. When the concn. of an active metal(s) selected from nickel, palladium and platinum is equivalent to an adequate catalyst amount, solder can be dissolved with the dissolving solution. In order to dissolve solder at a practical dissolution rate, a >2mg/l active metal concn. is preferred.  At this time, the higher the active metal concn. is, the higher the dissolution rate becomes, however, when the concn. is >200mg/l, no incremental effect is recognized and only the cost is increased.
