Title: Manufacture of semiconductor device
Inventor: KANAZAWA MASAO
IPC: H01L21/3213
Filed: 1980-12-29
Abstract: PURPOSE:To facilitate the removal of a bridge produced at the gap of a multilayer wiring, by providing a projection between regions where a lower layer wiring crosses two upper layer wirings, and photo-etching the upper layer wiring which remains at the end of projection after the formation of upper layer wiring. CONSTITUTION:For instance, a lower layer wiring 4 is formed on a field film 2 of element-formed substrate 1 in a shape that provides a horizontal projection 11 between regions where the wiring 4 is due to cross two upper layer wiring 8. Next, the upper layer wiring 8 is formed via an interlayer film 5, and a resist film 9 is coated. An opening 12 is provided at the end of a bridge 6 formed along the projection 11. Next, the end of bridge 6' is removed after etching evenly with etching material for the upper layer wiring 8. The resist film 9 is removed and the multilayer wiring structure is made. This facilitates removal of the bridge 6' and prevents the upper layer wiring 8 from over-etching. This also improves the yield and reliability of multilayer wiring.

Title: Filter for separating leucocyte
Inventor: KUROKI HITOSHI
IPC: A61M1/02
Filed: 1991-07-26
Abstract: PURPOSE:To separate leucocytes in blood efficiently and safely by using a porous body of a three-dimensional mesh-shaped continuous structure having continuous open pores as a filter. CONSTITUTION:A filter 1 for separating leucocytes has a construction wherein a porous body 5 formed of polyvinyl formal or polyurethane resin is supported by supporting materials 6a and 6b in a housing 4 having a blood inflow port 2 and a blood outflow port 3. The porous body 5 being the main component of the filter is constructed of a three-dimensional mesh-shaped continuous structure having continuous open pores of most frequent pore diameters 1 to 5mum. The diameters of the continuous open pores are 2 to 4mum desirably in view of clogging and a leucocyte retention rate, and the porosity rate is 75 to 95% desirably in view of the strength of the filter and a speed of separation. Since the flow passage of the filter is formed at the time when the porous body 5 is molded, nonuniformity is little and the possibility of an extraneous substance flowing out at the time of an operation is small. On the occasion of separation of the leucocytes, priming is made by a physiological saline solution and then the leucocytes out of blood constituents are retained by the porous body 5.

Title: Ballast mounting structure for discharge lamp apparatus
Inventor: HORIBE SHUICHIRO
IPC: H01F27/06
Filed: 1987-07-27
Abstract: PURPOSE:To eliminate the need for determining the mounting positions of auxilliary resonators according to places of installation and facilitate layout and execution of work, by providing the auxilliary resonators having resonance frequencies which tune with oscillation frequencies of a ballast to an oscillating system consisting of the ballast and an elastic supporter. CONSTITUTION:An elastic supporter 2 is stiff enough in terms of mechanical strength as an apparatus and supports a ballast 3 elastically. In such a case, as its elastic support is designed with emphasis on the practical strength, vibration transmissibility exceeds 1 with respect to basic frequencies 2fHz in the case of oscillations of its ballast 3. If the above state is left as it is, then vibration transmissiblity does not take reduced effect for the basic frequencies 2fHz. Under this situation, auxilliary resonators 4 which is adjusted to 2fHz is installed in the vicinity of the maximum extent of the amplitude of vibration at the elastic supporter 2. Thus the vibration absorption effect of the auxilliary resonators 4 lessens oscillations of 2fHz as well. This approach eliminates the need for considering the mounting positions of the auxilliary resonators 4 so as to absorb vibrations without lowering the practical supporting strength of the ballast 3.

Also with the rotation of the pulley 1, an envelope face 6 of a tooth part 5 of the toothed belt 2 is drawn, and on the basis of this envelop face 6 as a reference, a tooth profile face 7 of the pulley 1 is formed to keep a gap S on the opposite side of the tooth part 5 against the envelop face 6. The tooth profile face 7 is smoothly continued toward the tooth crest 3 via an escape part 8.

Abstract: PURPOSE:To get rid of influences of a residual impedance and a stray capacitance at a leading part of a coil by forming a capacitor using a electrode plate and an insulator on a part of the coil and connecting them through the coil to obtain a matching of impedance between the coil and an exterior circuit. CONSTITUTION:An RF coil is constituted of a coil 1, an outer cylinder 2, an inner cylinder 3, an electrode plate 4, an insulator 5 and a terminal 6 and the electrode plate is provided between the outer cylinder and the inner cylinder to form a capacitor thereof through the insulator. An impedance between both ends of the coil can be decreased. An exterior circuit is connected through this electrode plate. As the electrode plate connected with a part of the coil member and the exterior circuit is positioned through the insulator, it functions as a capacitor. Therefore, even when the coil is under a resonant condition and the impedance is high, it is divided by the capacitor and an impedance matching with the exterior circuit can be obtained. At the same time, as the capacitor can change the resonant frequency of the coil, tuning can be performed.
