Title: Filter material for molten metal
Inventor: OSHIRO TAKESHI
IPC: C22B9/02
Filed: 1998-04-27
Abstract: PROBLEM TO BE SOLVED: To prevent clogging of a filter material which filters a molten metal selected from zinc, aluminum, copper, magnesium and their alloys due to deposition of the molten metal, and to increase the filtering property by subjecting the contact face of the filter with the molten metal to plating with a specified alloy of zinc and aluminum. SOLUTION: This filter material consists of a metal or ceramic material and is suitable to filter inclusions (impurities) in a molten metal selected from zinc, aluminum, copper, magnesium and their alloys. The surface of the filter material to be in contact with the molten metal is plated with an alloy comprising zinc and >=0.1 wt.% aluminum. Since the alloy comprising zinc and >=0.1 wt.% aluminum can form a solid solution with the molten metal, it gives good wettability with the molten metal. Therefore, such a problem that, while filtering a molten metal, the molten metal deposits on the filter to cause clogging can be prevented.

Title: Manufacture of semiconductor film
Inventor: OYOSHI KEIJI
IPC: H01L21/263
Filed: 1990-05-02
Abstract: PURPOSE:To form a polycrystalline semiconductor film having large and uniform grain size or to realize a hetero epitaxial growth at a low temperature by so ion implanting from the surface of an amorphous semiconductor film containing crystal formed on a substrate as to make the projecting distance of the implanted ions longer than the thickness of the amorphous film. CONSTITUTION:An amorphous semiconductor film 2 containing a crystal phase 3 is formed on a substrate 1. For example, the nuclei of the phase 2 is partly formed on the film 2 deposited on the substrate 1 by a plasma CVD, a thermal CVD, etc., by ion implanting. The accelerating energy of the ions to be implanted from the surface of the film 2 is so set that the projecting stroke of the element to be implanted is larger than the thickness of the semiconductor film and the effect of converting to amorphous state due to cascade collision of the implanted ions to the atoms of the semiconductor film and a defect density in a region crystallized in the semiconductor film are reduced. The power density of the ion beam is desirably 0.5-1W/cm<2>. If the power density of the beam is low, the crystal growing speed can be increased by heating the substrate 1(at 50-800 deg.C) when it is ion implanted.

Title: Optical shutter device
Inventor: YUASA KAZUHIRO
IPC: G02B26/02
Filed: 1985-05-31
Abstract: PURPOSE:To control the position of dielectric liquid in a container, to control the transmission state of light and to improve reliability and speed up operation by providing the dielectric liquid in the container movably and controlling an electric field established in the container. CONSTITUTION:When switch contacts 7a and 7c are connected to each other, an electric field is established between a common electrode 3 and an on electrode 5 and the liquid 2 is therefore attracted to an area where the electric field is intense and positioned between the electrodes 3 and 5. In this state, incident light 8 passes through a shutter device and guided out as projection light 9. When switch contacts 7b and 7b are connected to each other, on the other hand, an electric field is produced between an off electrode 4 and the common electrode 3 and the liquid 3 moves to an area where the electric field is intense with its electric strain force and is positioned in the opposite area of the electrodes 3 and 4. At this time, the incident light 8 is cut off by the liquid 2, so the projection light 9 is not guided out. The time required for the movement of the liquid is short, so the light is brought under on/off control at a high speed.

CONSTITUTION:A multilayer interconnection structure consisting of a first insulating layer 34, first electrode patterns 36a, 36b, a second insulating layer 37 and second electrode patterns 39a, 39b is formed to cover the principal face of an N-type substrate 31 including active regions (base and emitter) 32 and 33. The second electrode patterns 30a and 30b have bonding regions 41a and 41b, under which contact regions 35a and 38a are aligned with and abutted against contact regions 35b and 38b, respectively, whereby metallic pillars are formed to extend substantially vertically to the principal face of the substrate. Since most of bonding pressure is exerted to these metallic pillars, an interlayer insulating layer will be subjected to less pressure. Accordingly, the interlayer insulating layer 37 is prevented from being cracked even at stepped parts thereof.

If so, a lamp drive circuit 40 energizes a relay 41, respective contacts 41a and 41b are selected to closure at the normally opened side, thus the circuit polarity is selected as well. With this constitution, sufficient safety is securable irrespective of the polarity of connection to the live line L and neutral line N of the power source.
