Title: Gradient magnetic field generating device
Inventor: HIGUCHI KEIICHIRO
IPC: G01R33/12
Filed: 1991-05-16
Abstract: PURPOSE:To provide the gradient magnetic field generating device which can generate a gradient magnetic field of high linearity. CONSTITUTION:Pairs of coils L1a, L1b, L2a, L2b...Lna, Lnb are placed coaxially on the Z axis (static magnetic field direction), and also, in symmetrically different positions by placing an origin O inbetween. To each pair of coils, a current is supplied frown power sources P1a, P1b, P2a, P2b,...Pna, Pnb, respectively. To each power source, a command signal for designating a current supplied to each coil is sent from a central controller 1. In the vicinity of the origin, different gradient magnetic fields are generated by plural pairs of coils placed in different positions, and the gradient magnetic field in the vicinity of the origin becomes that which is obtained synthesizing those gradient magnetic fields. Accordingly, by setting suitably a value (ratio) of a current supplied to each pair of coils a composite gradient magnetic field having an arbitrary gradient and high linearity can be generated.

Title: Column for continuous fluid separator using centrifugal force field
Inventor: TAKEUCHI MAKOTO
IPC: G01N33/48
Filed: 1986-06-17
Abstract: PURPOSE:To easily assure a desired sealing pressure and to prevent liquid leakage even in a static state by sliding a tapered part with a tapered part of a variable diameter ring by the force of a locking flange. CONSTITUTION:A column consists of the locking flange 1, the variable diameter ring 2, a spacer 3, and a column base 4. The ring 2 is expanded and is strongly pressed to the inside wall of the base 4 via the space 3 when the tapered part of the flange 1 is slid with the tapered part of the ring 2 by the force of said flange. The thickness of the spacer 3 held in place between the ring 2 and the base 4 is a channel groove. Since the spacer 3 is fixed to the ring 2, a liquid introducing port is set exactly to the narrowest position of the gap of a blanked part 13. The production and assembly are thus facilitated, and the desired sealing pressure is easily assured. The liquid leakage is thus prevented even in the static state.

IPC: H04N5/46
Filed: 1992-06-02
Abstract: PURPOSE:To display an image in a normal aspect ratio and to prevent doming from occurring when the image by a squeeze mode signal is displayed. CONSTITUTION:A video signal SV is supplied from a terminal 1 to a CRT 3 which performs display of aspect ratio of 4:3 via a processing circuit 2. Horizontal and vertical synchronizing signals from the processing circuit 2 are supplied to a deflection circuit 4, and a deflecting current is supplied to a deflecting coil 3C.

Title: Semiconductor laser element
Inventor: KASHIWADA YASUTOSHI
IPC: H01S5/00
Filed: 1984-07-11
Abstract: PURPOSE:To eliminate the absorption of a laser light at a reflecting surface and the temperature rise occurred by the absorption by bending and providing an active layer near the laser light emitting mirror. CONSTITUTION:An active layer 4 is bent near the reflecting surfaces 10, 11 for emitting laser lights 8, 9. The element is formed by forming Ga1-xAlxAs and GaAs layers 3, 4 on an N type GaAs substrate formed with grooves designated by hatched lines (e), (g) and then performing typical laser element forming steps. Thus, the laser light is not emitted via the active layer from the reflecting surfaces but emitted from a clad layer having wide forbidden band width adjacent to the active layer. Accordingly, the absorption of the laser light at the reflecting surface and the temperature rise by the absorption can be eliminated.
