Title: Forming method for circuit
Inventor: TOBA RITSUJI
IPC: C25D7/00
Filed: 1987-07-08
Abstract: PURPOSE:To stick a plating resist fast to a foundation metallic layer sufficiently, to prevent peeling during plating, to obviate an adverse effect on a plating film and to form a fine circuit by shaping a second metallic layer onto the surface of the foundation metallic layer forming the plating resist. CONSTITUTION:A hole 3 is bored at the required position of an insulation plate 1 with a metallic layer 2, and a metallic thin-film 4 is shaped onto the metallic layer 2. A second metallic layer 5 is formed onto the metallic thin-film 4 or the metallic layer 2. A metal having an ionization tendency larger than a metal for pattern plating used in a postprocess or a metal from which an oxide is difficult to be produced is proper to a metal forming the second metallic layer 5. Sections except a desired circuit forming section are masked with a plating resist 6. A circuit is formed through pattern plating 7. Circuits up to the last can be formed through a conventional method. Accordingly, the plating resist is not peeled from a foundation metallic layer on pattern plating, thus acquiring a sufficient effect for shaping a fine circuit.

Title: Beam width variable antenna
Inventor: OGASA MITSUAKI
IPC: H01Q3/00
Filed: 1993-07-08
Abstract: PURPOSE:To operate the pulling-in, capturing, and following-up operation of the other satellite, and to make an antenna compact by switching the switch of a power feeding part for communication between satellites, and changing the antenna aperture area of a radio wave radiated from a primary radiator. CONSTITUTION:A beam radiated from a main primary radiator 1 widely reaches a sub-reflecting mirror 19 as shown by AA', and it is reflected on a main reflecting mirror 18, and finally the radio wave is radiated from a wide antenna aperture face BB'. On the other hand, the beams radiated from a main primary radiator 1 and a sub-primary radiator 2 are made thin, and the radio wave narrowly reaches the sub-reflecting mirror 19 as shown by CC'. Therefore, the radio waves reaches the main reflecting mirror 18 in narrow wide, and an antenna aperture face DD' is made narrow. At the time of pulling-in the radio wave from the other satellite by the capturing operation, a distributor 13 of the power feeding part for communication between the satellites is turned on, and the beam is made thick by using the plural primary radiators in a satellite (a) at a radiation side. Thus, an other satellite (b) can easily pull-in the beam of the satellite (a). At the time of starting communication, the distributor 13 of the power feeding part for communication between the satellites is turned off, the beam is made thin, a gain is increased, and the communication is operated.

Title: Lead frame for semiconductor device
Inventor: HORIUCHI KOJI
IPC: H01L23/50
Filed: 1985-07-31
Abstract: PURPOSE:To prevent moisture resistance from decreasing by reducing the thickness of a boundary between the inner leads of a sealing resin and the outer leads out of the resin thinner than other portion by half etching or coining by pressing. CONSTITUTION:A boundary 4 between the inner lead 2 in a sealing resin 1 and outer leads 3 out of the resin is formed thinner than other portion (the inner leads 2, the outer leads 3). Since the boundary 4 between the inner leads and the outer leads is thinner than the other portion, if the leads are bent, force necessary to bent the leads may be smaller than the conventional lead frame, and since the boundary 4 can be readily bent, the force when the lead is bent is not almost transmitted to the resin. Thus, since no resin crack or gap occurs, it can prevent water from invading through the gap to enhance the reliability.
