Patent JP-H0448683-A (JP)
Title: Manufacture of printed circuit board
Inventor: IKEDA YUICHI
IPC: H05K3/42
Filed: 1990-06-14
Abstract: PURPOSE:To completely neutralize acid left in a through hole by using alkali gas for neutralization with alkali after acid washing in a process of activation of the surface of the copper of a printed circuit board. CONSTITUTION:The copper of a substrate is rinsed in a rinsing process 1, pickled in acid liquid such as sulfuric acid and hydrochloric acid in an acid washing process 2, and rinsed in a rinsing process 3. In an alkali neutralization process 4, alkali gas such as ammonia gas is used for neutralization instead of alkali water solution used conventionally. As a result, the alkali gas for neutralization enters a through hole hard to fill with liquid, therefore, acid left is completely neutralized. The copper is rinsed in a rinsing process 5 to complete activating the surface thereof. The substrate having the copper the surface of which is thus activated is post-treated in a post treatment process 6 such as a printing process, a pre-fluxing process, and an etching process.

Title: Vane type compressor
Inventor: TAKAO KUNIHIKO
IPC: F04C29/12
Filed: 1981-10-02
Abstract: PURPOSE:To improve the performance of a vane type compressor, by reducing pressure loss in a low-pressure passage for drawing a coolant gas by forming the low-pressure passage in a front cover attached to a front plate of the compressor helically in the direction of rotation of a rotor. CONSTITUTION:A rotor 6 having a plurality of vanes 5 is disposed in a hollow space defined by a front plate 1, rear plate 2 and cam ring 4. A cooling medium drawn from a coolant inlet port 15 formed in a front cover 10 is introduced into a compression chamber 17 from a suction port 18. Here, since a low-pressure chamber 16 constituting a low-pressure passage is formed in the front cover 10 helically in the direction of rotation of a rotor in the manner that it is connected to the inlet port 15 and no projections or recesses are formed in the low-pressure passage 16, it is enabled to reduce pressure loss by imparting pre-whirl to the coolant.

Title: Document stand
Inventor: OKADA TOMIRO
IPC: A47B65/00
Filed: 1989-06-19
Abstract: PURPOSE:To hold documents having a relatively thin thickness by providing a coupling means for coupling a holding member and a document support member so as to stand the document support member in an inclined posture. CONSTITUTION:A holding plate 24 is rotated about a hinge 22 to a position where it is laid on an extension of a document loading plate 12, and a document support plate 16 is also rotated about a hinge 14 to a position where it is laid substantially in parallel with the document loading plate 12. Accordingly, the overall thickness of the document stand 10 which is in a folded condition becomes thin so that it can be easily handled. Documents P set on a friction member 18 are supported by the document support plate 16 in an inclined posture. Even though the thickness of the documents P is thin, the dead weight of the document P is mainly born by the document support plate 16, and accordingly, the component of the dead weight of the documents P along the surface of the documents P, that is, the force which is given by the dead weight of the documents P at a standing angle is extremely small so that the documents P never buckle. Further, since theses documents P abut against the friction member 18 so as to produce a friction force at the lower end part, the documents P never slip on the friction member 18.
