Title: Manufacture of printed wiring board
Inventor: KOMATSU TAKATSUGU
IPC: H05K3/34
Filed: 1989-04-08
Abstract: PURPOSE:To perform highly reliable plating by providing a hole with a stepped part forming a large diameter and a small one in a substrate material and after that, providing a through-hole with a stepped part. CONSTITUTION:A hole is made on the halfway of depth of a substrate 2 consisting of a laminated plate where copper is placed on both faces of its plate with a large-diameter drill and after that, the hole is made from the rear side of the plate with a small-diameter drill. Then the hole equipped with a stepped part is made. Then, if a circuit is formed by performing plating 3 at a thorough-hole, a through-hole substrate 2 equipped with the stepped part is manufactured. In this way, as a large-diameter hole 6 is made on the halfway and a small-diameter hole is made at a remainder of the board having a thin material, it is easy to make the small-diameter hole. Since the small- diameter hole has a small aspect ratio and the hole is opened, highly reliable plating is thus performed.

IPC: H05K3/00
Filed: 1994-04-27
Abstract: PURPOSE:To manufacture the ceramics substrate for a thermal head in a short period of time by a method wherein ceramics green sheet, on which V-grooves are formed by extrusion at equal space intervals with pointed blades provided at the lip of the die of an extruder, is burnt. CONSTITUTION:Ceramics green sheet 1 is formed by extruding molding material made of ceramics powder with an extruder 5. On the lip 4 of the die of the extruder 5, pointed blades 3 are arranged. Thus, on the extruded green sheet 1, V-grooves 2 are engraved to its flowing direction. After that, the green sheet 1 is burnt and divided at the grooves 2 so as to produce ceramics boards. After that, breaking lines are formed with laser on the ceramics board to the direction crossing to its extrusion direction. By dividing the ceramics board at the breaking lines, a large number of printed wiring boards are obtained. Accordingly, since only breaking line to the crossing direction are necessary, the time of a laser consumed can be shortened and the production efficiency of the ceramic board can be improved.

Abstract: PROBLEM TO BE SOLVED: To facilitate filling of lubricating oil by forming an oil filling port for lubricating oil on an upper surface of a cylinder head. SOLUTION: Lubricating oil reserved in an oil pan is filled from an oil-filling port 50 formed on an upper surface of a cylinder head 8 and is closed by an oil cap 51. The oil-filling port 50 is disposed upward of a valve end part 52, preferably disposed directly above it. The oil-filling port 50 for filling lubricating oil is formed on the upper surface of the cylinder head 8, and thereby the oil- filling port 50 approaches a ship body side, and lubricating oil is easily filled. If the oil-filling port 50 is to be arranged upward of a valve system 20 such as a valve end part 52, preferably directly above it, lubricating oil filled from the oil-filling port 50 flows down from each member of the valve system 20. Since mechanical loss is reduced when an engine is started immediately after the lubricating oil is filled, startability of the engine is improved.

Abstract: PURPOSE:To economically and evenly cool bearing portions by connecting two heat receivers with a single condenser through each vapor line and further communicating the condenser with the two heat receivers through each liquid line. CONSTITUTION:When temperature rise of a bearing portion on a heat receiver 1 side becomes greater than that of a bearing portion on the other heat receiver 11 side, working liquid in the heat receiver 1 upon vaporizing generates vapor quantity, vapor pressure and vapor temperature which are greater than those of working liquid in the heat receiver 11 to be derived of greater latent heat of vaporization and thereby to cool the bearing portion on the heat receiver 1 side, namely to hold the temperature rise of the bearing portion on the heat receiver 1 side at a lower level than that of the bearing portion on the heat receiver 11 side. Then, hot vapor vaporized in the heat receiver 1 and cool vapor vaporized in the heat receiver 11 are introduced through vapor lines 1 and 31, respectively to a condenser 5 to be cooled. Liquid condensed in the condenser 5 is divided and returned through liquid lines 4 and 41 to the heat receivers 1 and 11, respectively. Accordingly, temperature of the liquid to be returned to the heat receiver 1 becomes higher and temperature as to the heat receiver 11 becomes lower, thereby increasing the temperature rise of the bearing portion on the heat receiver 11 side and as a result, holding the difference of temperature rise between both bearing portions at a minimum level.
