Title: Manufacture of thin-film circuit
Inventor: MORIJIRI MAKOTO
IPC: H01L21/302
Filed: 1986-07-02
Abstract: PURPOSE:To enable a reattaching layer to be prevented from being produced when a pattern is formed by ion-beam etching method, by using a film, which composes a thin-film circuit, as a mask material and then performing patterning of this film by wet-etching method. CONSTITUTION:A metallic film 4 is coated with a resist 5. A pattern shape to be formed is obtained by using this mask in the processes of exposure and developing. The resist pattern is then used as a mask to etch the metallic-film pattern. Then, the metallic-film pattern with no reattaching layer is used by wet-etching method. This metallic-film pattern is used as a mask when ion-beam etching is performed. The formed resist pattern is then removed to form a new metallic-film pattern so that the mask material pattern for the ion-beam etching process can be formed. Ion beams are then radiated with the metallic- film pattern serving as a mask, to etch the conductive film. Successively the attaching layer is etched to complete the formation of the pattern.

Patent JP-H0320978-A (JP)
Title: Connector
Inventor: ONO MICHIAKI
IPC: H01R13/66
Filed: 1989-06-19
Abstract: PURPOSE:To prevent a surge current with high electric resistance immediately after a connector is connected by providing a metal with a resistor at the front section of the conducting portion of a jack, and providing a metal with no resistor at the rear section. CONSTITUTION:When a plug casing 1 and a jack casing 3 are connected, a plug pin 2 is first brought into contact with a jack 6 added with a resistor 5. If either one is on a hot line, a surge current tends to flow, but the current quantity is limited by the added resistor 5. When the current is returned to the stationary state, the pin plug 2 is brought into contact with a jack 4 with no resistor at the rear section. The resistor 5 is neglected although they are connected as before, and the surge current can be prevented. When the plug casing 1 is connected to the jack 6, the electric resistance of the plug pin 2 is increased. When the jack 6 is first brought into contact, the resistance value of the pin 2 is large, and the resistance value is decreased as it is inserted. The surge current is limited even if the connection portion is in the hot line state.

Title: Production of semiconductor film
Inventor: OOMURA KAZUMICHI
IPC: H01L29/78
Filed: 1981-09-30
Abstract: PURPOSE:To form a highly uniform semiconductor film allowing carriers to readily  move on an insulating substrate by a method wherein a small piece of a thin film is  formed at such temperatures that crystallization will not occur on the surface of an  amorphous semiconductor film and a crystalline nucleus is produced by annealing so as  to uniformly crystallize the amorphous semiconductor film by causing the film to grow  in a solid phase. CONSTITUTION:An amorphous Si film 2 is formed on top of a Si monocrystalline  substrate 1 where a thermo-oxidized film has been formed and small pieces of SiO2  films 3 are formed on top of the amorphous Si film in the form of a grit. If these  small pieces are annealed at relatively low temperatures, a crystalline cleus 4 is produced on the periphery of each small piece of the SiO2 film. Crystalline particles grow  with the crystalline nucleus 4 as the center according to the growth in a solid phase,  so that a polycrystalline Si film 5 having uniform particles in diameter is obtainable  over the whole surface of the wafer. Thus, highly uniform semiconductor films offering  excellent element characteristics can be manufactured. Moreover, since annealing is  conducted at temperatures that are unable to fuse the semiconductor film, this manufacturing method is useful when the elements have already been formed on the substrate integratedly or when three-dimensional IC's are formed.

IPC: F15B13/04
Filed: 1995-05-31
Abstract: PURPOSE: To decrease a volume of a packed material as much as possible for decreasing costs of transportation, storage, and processing of the material. CONSTITUTION: Material 12 such as trash or refuse is packed in a container 10 by an opposed hydraulic packing cylinder 16 and a hydraulic ejecting cylinder 20. Each cylinder is controlled by hydraulic control valves 64 and 66, and the control valve 66 for controlling the ejecting cylinder is, in effect, operated by the control valve 64 for the packing cylinder. This is accomplished by sensing the pressure applied to the packing cylinder, and when this pressure reaches a predetermined level, a pilot damp valve 104 in the ejecting cylinder 20 is opened to allow a piston 42 in the ejecting cylinder to retreat. When the pilot pressure drops below a predetermined level, the pilot damp valve 104 closes, allowing the packing cylinder to exert additional packing force. In this way the piston in the ejecting cylinder inches back and the material is intermittently packed.
