Title: Magnetic disk cartridge
Inventor: OISHI KENGO
IPC: G11B23/03
Filed: 1996-09-30
Abstract: PROBLEM TO BE SOLVED: To prevent a magnetic disk cartridge from being misloaded into a small- capacity type disk driving apparatus, and prevent dust from entering the magnetic disk, by locking a shutter member at a closing position so as to prevent the shutter member from unnecessarily opening, thereby achieving high reliability. SOLUTION: The magnetic disk cartridge can rotatably house a large-capacity disk-shaped magnetic disk medium 6 within a case 2. The case 2 is provided with openings 11 and 12 through which a magnetic head is to be inserted, and a shutter member 13 for opening and closing these openings 11 and 12. The case 2 has a planar shape which is common to a small-capacity magnetic disk cartridge, while a size in the thickness direction of the case 2 is about 1.3 to 2.0 times as thick as the smallcapacity magnetic disk cartridge, thereby preventing misloading. The case 2 has a locking member 4 for locking the shutter member 3 at a closing position, while a recessed portion 25 is formed on a front end face 2c of the case into which a shutter opening and closing pin is to be inserted at the initial period of the opening operation.  A portion of the locking member 4 is exposed in the recessed portion 25. The shutter opening and closing pin is allowed to come into contact with the locking member 4, thereby releasing its locking condition.

Title: Manufacture of semiconductor device
Inventor: TEZUKA TATSURO
IPC: H01L21/76
Filed: 1988-10-14
Abstract: PURPOSE:To manufacture easily a refined semiconductor device with a relatively simple process by forming an insulating film without using thermal oxidation and photo-lithographic techniques. CONSTITUTION:A trench provided in a semiconductor substrate ]is buried with a polycrystalline silicon layer 4 and after that, the polycrystalline silicon layer 4 of a part of the trench is etched with a reactive ion etching process so that the surface of its layer 4 is lower than that of the semiconductor substrate. Then a nitride film 5 grows with a low pressure chemical vapor deposition process and the surface is leveled by spin-coating an applied film 6 and the nitride film 5 is left only on an upper part of the trench after etching the whole face. As the polycrystalline silicon layer 4 in the trench is not thermally oxidized, no intense stress is establishing in the semiconductor substrate 1. Then the distance between the trench and the emitter of a transistor is shortened while making the nitride film 5 thick sufficiently with an insulating film located on the upper part of the trench. The refined device is thus obtained without lowering the reliability of the semiconductor device.

Title: Printed wiring board and its soldering
Inventor: SHIBA JUNYA
IPC: H05K3/24
Filed: 1993-10-15
Abstract: PURPOSE:To inhibit the potential formation of a solder bridge and check the marked drop in mounting efficiency. CONSTITUTION:Diamond-shaped lands 3 and 4 are formed on the surface of a printed wiring board body 2 where the spacing between the lands 3 and 4 along their center line is widened to ward their side edges. A conductor pattern 7 is formed so as to connect the lands 3 and 4 linearly on one side end in the center line of the lands 3 and 4 where a solder resist 8 is coated and formed on the conducting pattern 7. The direction in which the conducting pattern 7 is formed with the lands during flow soldering, is adapted to be an advancing direction of a printed wiring board 1 with a soldering tank. Since the conducting pattern 7 is formed in an area having a wider spacing between the lands 3 and 4, the slightly longer conducting pattern 7 is formed, which makes it possible to lengthen the coated area of the solder resist 8. Furthermore, the occupancy area of the conducting pattern 7 will not be increased dramatically.
