Title: Drainage system
Inventor: OHASHI SHOICHI
IPC: E03F5/22
Filed: 1994-07-27
Abstract: PURPOSE:To prevent the generation of a water-hammer phenomenon by providing a by-pass circuit at the intermediate part of longitudinal pipelines while providing a drain means at the intermediate part of horizontal pipelines, and closing switching valves only at the operating time of a drainage pump. CONSTITUTION:A check valve 5, and a drain means D formed of a switching valve 10 and a drain pipe 11 are provided at the intermediate part of horizontal pipelines K1, K1 in a drain pipeline K. A check valve 6, and a by-pass circuit B formed of a switching valve 20 and a by-pass pipe 21 are provided at the intermediate part of vertical pipelines K2, K2. Both switching valves 10, 20 are closed by a control device 30 only at the operating time of a drainage pump P. Water conveyed from the drainage pump P is therefore drained outside of a vertical shaft 1 directly through both check valves 5, 6. When the operation of the drainage pump P is stopped, both switching valves 10, 20 are opened, and the drain means D and the by-pass circuit B are opened, so that residual water in the pipelines between both check valves 5, 6 and in the position higher than the check valve 6 is drained from the drain means D. A water-hammer phenomenon is not therefore generated at the time of restarting the drainage pump P.

Title: Magnetic bubble memory element
Inventor: KONDOU HIRONORI
IPC: G11C19/08
Filed: 1982-11-10
Abstract: PURPOSE:To enlarge a bias magnetic field margin when a magnetic bubble goes across transfer patterns by specifying ratio of length of a magnetic bubble transfer pattern in the direction that intersects the direction of transfer to the length of leg. CONSTITUTION:A magnetic bubble transfer pattern 10 formed on a magnetic film that allows existence of magnetic bubble and made up of soft and strong magnetic bodies that transfer the magnetic bubble is formed to satisfy the relation l>=0.4h where (h) is the length of pattern in the direction that intersects the direction of magnetic bubble transfer, and (l) is the inner length of a leg pattern 10a. By this constitution, minimum value GAMMAHB2 of magnetic field margin near 180 deg. of rotating magnetic field direction in which upper limit value of bias magnetic field is lowered becomes gradually greater. By forming the shape of transfer pattern 10 to make the inner length (l) of the leg pattern 10a greater than 0.5h, magnetic field margin near 180 deg. of the direction of rotating magnetic field can be enlarged to nearly maximum value GAMMAHB1.

Title: Magnetic recording medium
Inventor: IKUYAMA SEIICHI
IPC: G11B5/708
Filed: 1988-08-08
Abstract: PURPOSE:To improve durability of the magnetic layer without degrading the electromagnetic conversion characteristic as small as possible by incorporating a powder of tungsten compound as an additive into the magnetic layer. CONSTITUTION:The powder of tungsten compound with specific gravity between >=15 and <=18 is incorporated into the magnetic layer at the proportion of 20-80 pts.wt. of tungsten compound to 100 pts.wt. of magnetic powder. As the tungsten compound used as the additive has a specific gravity as large as 15 to 18, the volume fraction of the additive in the magnetic layer is small, which gives little influence to reduce the saturated magnetic flux density (Bm). Therefore, the tungsten compound powder can be incorporated as much as 20-80 pts.wt. into 100 pts.wt. of magnetic powder of the magnetic layer. Hardness of the tungsten compound is about 9 of Mohs hardness. It is hard enough that a proper polishing property can be obtained by selecting the mean particle size of the powder between 0.05-1.0mum, which can maintain a clean surface of a magnetic head. Thus, durability of the magnetic layer can be improved without degrading the electromagnetic conversion characteristics as small as possible.

Title: Semiconductor device and tape carrier
Inventor: ARAKI ISAO
IPC: H01L21/60
Filed: 1987-08-07
Abstract: PURPOSE:To prevent misregistration of an inner lead and an electrode and to improve bonding yield by applying a reinforcing tape to the rear of a junction of an inner lead connected to a chip electrode to reinforce the inner lead. CONSTITUTION:In an inner lead 2 of a tape carrier 10 for tape automation bonding, a reinforcing tape 3 for each inner lead is applied to the rear of a junction 4 of the inner lead 2 connected to an electrode of a chip 5. The inner lead tip is thus reinforced and does not break or bend even if external force is applied. Misregistration of the inner lead 2 and the electrode is thereby prevented and bonding yield is improved. Moreover, because the reinforcing tape absorbs external force at bonding, unsymmetrical working is also avoided.

Title: Heat collecting device with flexible bag
Inventor: TAKAHASHI TAKASHI
IPC: F24J2/04
Filed: 1991-05-01
Abstract: PURPOSE:To prevent a residual liquid from being remained at a bottom part of a bag by a method wherein a bag wall is closely fixed to a surface of a rear side of a thermal collecting member, thermal medium liquid is discharged to the thermal medium liquid receiving surface at an upper end of the bag and the bag bottom part of the thermal collecting device for flowing down the liquid at the surface of the rear side of the bag wall is inclined. CONSTITUTION:An upper end of a bag wall 11 of a bag 10 contacted in its surface with a thermal collecting member 1 is bent and deformed upwardly. Its rear surface forms an inlined surface fir receiving thermal medium liquid. The thermal medium liquid discharged from a thermal medium liquid supplying means 4 is dispersed while being flowed down along a thermal medium liquid receiving surface 3 and flows down to the rear surface of the bag wall 11 from a curved surface 4. A lower end of a bag 10 receives the thermal medium liquid flowing down and feeds it back to a heat accumulative tank. With such an arrangement, the thermal medium liquid is enclosed within a closed spacing and no leakage of vapor is found, a positive thermal collection can be carried out. Since the bag bottom part is inclined, the liquid does not drip from the bag wall or the thermal medium liquid dew formed at the bag bottom part is not remained in the midway part of the bag bottom part.

Title: Method and apparatus for controlling life time of minority carrier in semiconductor device
Inventor: NEILSON JOHN MANNING SAVIDGE
IPC: H01L21/332
Filed: 1998-06-29
Abstract: PROBLEM TO BE SOLVED: To make the density of recombination centers in a buffer layer in the vicinity of the blocking layer of a semiconductor device higher than the blocking layer, by joining two wafers so that their junction planes may not align, and that strains to form recombination centers may be formed in the junction interface. SOLUTION: Junction planes are misalined intentionally and treated according to the properties of the junction surfaces 30, so that strains may be generated, at the time of joining two wafers 32, in the junction interface between the wafers by misalignment of their properties. For example, one wafer 32 is rotated against the other, and the crystal axes of the two wafers 32 are caused to differ. Strains are generated in the Junction interface between wafers of both junction planes 30, and a buffer layer is formed here, and the density of recombination centers becomes fairly higher than a blocking layer. Consequently, it becomes possible to control the life time of minority carriers.
