Patent JP-H02234495-A (JP)
Title: Manufacture of copper plate-containing multi-layered printed board
Inventor: KODAMA TOSHIRO
IPC: H05K3/46
Filed: 1989-03-07
Abstract: PURPOSE:To prevent the reliability of a printed board from being lowered owing to any crack by applying no oxidization or surface roughness treatment to a release hole circumferential part of a copper plate. CONSTITUTION:An oxidization (black oxide) or surface roughening treatment is applied to the surface of a copper plate 1, and then a release hole 11 is formed. Accordingly, there is applied no oxidization or surface roughening treatment to the internal circumferential surface of the release hole 11, permitting close contact of that portion with resin is weakened and hence any distortion to be concentrated around that portion. Hereby, any crack is formed along the internal circumferential surface of the release hole 11. Even if any through- hole is formed through copper-clad substrate, any produced crack is located far away from the internal wall surface of the through hole. Thus, any lack of plating and deterioration of any insulating property are eliminated to improve the reliability of a printed board.

Abstract: PURPOSE:To shorten the time required for the data saving/restoring processes by adding a data compression/expanding function to a route for data which are saved and restored between a semiconductor storage circuit and a saving storage in a semiconductor electronic disk device. CONSTITUTION:When a data saving action is started with an instruction given from a host device for saving of data, a semiconductor electronic disk control part 11 gives an instruction to a data compressing/expanding part 13 to compress the data and then gives an instruction to a semiconductor storage circuit 12 to read out the data via the part 13. At the same time, the part 11 gives an instruction to a saving storage controller part 14 to write the data into a saving storage 15. The part 13 receives the data from the circuit 12 and compresses the data, and the part 14 receives the compressed data from the part 13 and writes this data into the storage 15. As a result, the time required for data saving/restoring processes can be shortened.

Title: Food materials baking devices
Inventor: NARAMURA NORIYUKI
IPC: A47J37/06
Filed: 1994-03-25
Abstract: PURPOSE:To enable easy taking out of baked food from a heating plate of baking devices, even when its materials are apt to stick on the heating plate, by way of providing enforceable detaching means that can move upward and downward for pushing off baked foods, in a form of projecting hand coming out of a heating plate that may be subject to the stick problem, when the top and bottom heating plates open apart. CONSTITUTION:When baking of a heel H (lower side bread for hamburger) by a pair of heating plates is completed and two of the heating plates 8 come apart, there come out enforceable detaching plates 10, projected from the top heating plate 8, that is apt to lead to stick problems, and the detaching plate, therefore, pushes the heel H off from the heating plate. Thus it can certainly take the heel off even though its materials may be stickable on the heating plate 8. Further, when the top heating plate 8, which may be subject to sticks, is lifted upward, and both plates come wider apart, the heel H, pushed off from the heating plate 8 enforceably, falls upon the bottom heating plate 8. And then, it becomes quite easy to take out the baked heel H by pushing it horizontally with a pushing device or something.
