Title: Magnetic head
Inventor: OKAMURA HIROSHI
IPC: G11B5/265
Filed: 1985-12-27
Abstract: PURPOSE:To improve SN ratio of read out data by forming a non-magnetic part on an erasing gap and making the degree of magnetic coupling between the erasing gap and a magnetic disk smaller than the degree of magnetic coupling between a read/write gap and the magnetic disk. CONSTITUTION:A read/write core 2 and an erasing core 4 are joined to make an erasing gap 2a positioned farther off from a magnetic disk D than a read/ write gap 1a by (d), and a non-magnetic material layer 6 is formed on the erasing gap 2a. When a distance of (d) exists between the gap and magnetic disk, reproduction output is reduced by 55d/lambda (dB) (lambda is wavelength of reading signal). Thus, when the magnetic head caused off track, noise is mixed to reproduced signals from a coil 4. However, the intensity of magnetic field that arrives at the erasing gap lowers and magnetic induction generated in the erasing core 2 also becomes small. Accordingly, noise intermixed in reproduced signals outputted from the coil 4 wound on a read/write core 1 decreases.

Title: Submount for optical semiconductor element
Inventor: ISHII MITSUO
IPC: H01S5/00
Filed: 1987-11-25
Abstract: PURPOSE:To enable a fine control of a superficial solder layer in thickness and obtain a submount stable in mechanical strength by a method wherein barrier layers are provided to both faces of a submount substrate and moreover solder layers are formed thereon. CONSTITUTION:An alloy solder layer 9 of Au80-Sn20 is formed on a barrier layer 30 as a solder layer and a thin Au layer is continuously formed thereon through, for example, evaporation. The alloy solder layer 9 of Au-Sn is formed through evaporation, and moreover the Au layer 10 is thinly formed on the top face of the alloy solder layer 9, so that the alloy solder layer 9 is remarkably decreased in the defective exterior appearance which is caused by the superficial oxidation of the layer 9 even at standard temperature after a die- bonding. As the Au layer 10 is formed on the top surface, the decrease in an adhesive property due to the deviation in composition of Au-Sn due to the ununiformity of a conventional Sn plating in thickness can be remarkably alleviated.

Title: Temperature detecting optical cable
Inventor: OTA JUNICHI
IPC: G01K11/12
Filed: 1989-11-16
Abstract: PURPOSE:To improve the accuracy of temp. measurement by juxtaposing an optical fiber which is doped with a metal element or rare earth element and an optical fiber which is not doped with the element in a part of a part where light propagates. CONSTITUTION:Both of the optical fibers 1, 2 are optical fibers for general communication having 9mum core diameter and 125mum clad diameter and 0.3% difference in refractive index. These fibers are primarily coated with a silicone resin and are juxtaposed in an aluminum pipe 3 via an aluminum spacer 4. The metal element, such as copper, and the rare earth element, such as holmium, are doped in the optical fiber 1. While the fluctuations in the loss based on the coefft. of linear expansion arise similarly with the optical fibers 1, 2, the increase in the loss based on the doping of the elements arises only in the one optical fiber if the fibers are constituted in such a manner and, therefore, the fluctuations in the loss based on the coefft. of linear expansion and the increase in the other losses are offset by comparing both. The measurement accuracy is thus improved.

Filed: 1992-11-09
Abstract: PURPOSE:To powerfully remove various foreign objects on the upper surface of a semiconductor wafer, by including a nozzle angle change means for periodically changing the angle of a spray nozzle with respect to the upper surface of the semiconductor wafer during spraying. CONSTITUTION:After the pure water spraying from a spray nozzle 5 is started, a motor 9 starts to rotate, the power of which is transmitted through a belt 12, an intermediate shaft 11 and a belt 13 to a rotating shaft 10. Then, the spray nozzle 5 fixed to the rotating shaft 10 starts to rotate around the rotating shaft 10. When the anble theta formed by the center line of the spray nozzle 5 and the normal line of the upper surface of a semiconductor wafer 1 becomes a fixed angle plus theta0, the rotation of the motor 9 is reversed to swing the spray nozzle 5 in the opposite direction. By this, the spray angle of a cleaning material with respect to the upper surface of the semiconductor wafer becomes a wide range, whereby various foreign objects on the upper surface of the semiconductor wafer can be powerfully removed.
