Title: Digital magnetic head
Inventor: NAKAYAMA MASAO
IPC: G11B5/265
Filed: 1986-07-17
Abstract: PURPOSE:To improve S/N by setting the width of a track width adjusting nonmagnetic part to a value wider than the width of a read/write gap to not only extend the distance margin to an adjacent track but also widen the effective recording track width. CONSTITUTION:In a bulk type tunnel erase magnetic head, the width of track width adjusting nonmagnetic parts 16 and 20 provided in the center of an erase core 12 is set to a value wider than the width of a gap 10 of a read/write core 10. The interval in an erase track is slightly wider than the recording track width, and both end parts of the recording track are erased only by the fringe effect of the erase gap. Consequently, the extent of off-track can be increased up to adjacent tracks to maximize the off-track margin on the condition of a certain track pitch when the read operation is performed by the read/write core 10. Since the recording track width can be effectively widened, S/N is improved.

Abstract: PURPOSE:To form a conductor wiring in uniform thickness by making the area of an upper layer larger than that of a lower layer in the area of the opening of the through-hole of an insulating film. CONSTITUTION:An SiO2 film 32 is bored on a P layer 31, the opening is clogged by an Si3N4 film 32', an Si3N4 film 33 is superposed through a CVD method, a resist mask 40 is formed, and the film 33 is bored 38 through plasma etching. The resist mask 40 is formed, and the film 32' is bored by buffer fluoric acid by using an opening 39 smaller than the opening 38.

Inventor: TAKEZAKI YUKIYA
IPC: H01L21/22
Filed: 1979-12-27
Abstract: PURPOSE:To reduce the unevenness of the concentration of impurities in a diffusion layer by etching the diffusion layer on a semiconductor substrate with application of a resist mask and then by covering the diffusion layer and the exposed surface of the substrate with an insulation layer. CONSTITUTION:A P layer 2 is provided on the N type Si substrate 1 and the resist mask 4' is applied thereto. The P layer 2 is etched by a liquid wherein hydrofluoric  acid, nitric acid and acetic acid are mixed and thereby a layer 2' is formed, while  the substrate 1 is slightly removed by etching. Next, the mask is removed and the  layer 2' and the substrate 1 are covered with an SiO2 film 13. By this method, the  resistance of sheet due to the unevenness of the density of the P layer is remarkably  reduced. In addition, heating for forming the SiO2 film is conducted only once,  which is effective for improving the property of the device and for curtailing the  process for manufacturing the same.

Title: Channel device
Inventor: SHIBATA HIDEAKI
IPC: G06F13/42
Filed: 1986-07-21
Abstract: PURPOSE:To prevent the breakage of the data on a memory by reporting the abnormal end of data transfer to a program given from a channel device. CONSTITUTION:A channel device 2 detects the generation of a data overrun while transferring data by a data streaming system and therefore sets an FF at 1, for example, to show the generation of the data overrun. When the transfer of data is through, the device 2 checks the unit check bit of a device status byte reported from an input/output controller 3. Then the device 2 sets abnormally the interface control check bit of the channel status byte as long as the FF is kept at 1 although the corresponding check bit is normal and reports this fact to a program. Thus it is possible to prevent the data breakage of a memory caused by the abnormality of an IO interface cable or the controller 3.

Title: Noncontact polishing device
Inventor: MINAMIYAMA TAKAYUKI
IPC: B24B37/00
Filed: 1983-09-14
Abstract: PURPOSE:To reduce the occurrence of damage and machining irregularities as well as to aim at improvements in quality, by embedding a first magnet in a machining table surface and a second magnet in a holding surface of a work holder, respectively, while polishing a work in a way of floating it off the table top by means of repulsion inherent in each magnet. CONSTITUTION:Removing a work holder 6, a semiconductor wafer is held on a bottom surface part and inserted into a holder 4. Then an electromagnet 7 is excited, and when its exposed side is set down to an S pole, the magnet 7 and the holder 6 are repulsed with each other whereby the holder 6 floats off a machining table 1. Next, the machining table 1 and a spur gear 3 are rotated, and when simultaneously fluid abrasive grains are fed onto the table 1, both holder 4 and 6 rotate each whereby these abrasive grains get in space between the wafer and the table 1 at high speed following rotation in the machining table 1, thus polishing the wafer takes place. Like this, even in time of starting and finishing, the wafer floats off the table without fail and thereby on no consideration should it come into contact with the machining table 1 so that the occurrence of any damage to a clutch or the like is well reduced, improving a yield rate in production and keeping it horizontal, and machining irregularities is thus reduced, besides improvements in quality.

SOLUTION: At the lower side of a cover plate 75, a suction pipe 88 to connect to a suction hole 82 is provided, and a check valve 89 is provided in the suction pipe 88. The suction pipe 88 sucks the lubricating oil OIL stored at the inner bottom part of an enclosed housing 31. The check valve 89 blocks the flow of the oil reverse to the oil flow when an oil pump P is operated in the rotation of the regular direction. That is, the flowing of the lubricating oil OIL inside a cylinder chamber 72 discharged to the inside of the housing 31 passing through the suction pipe 88, operated by the reverse rotation of a driving shaft 35 is blocked. Consequently, the oil pressure in the oil feeding pump P is raised, and the reverse rotation of the oil feeding pump P is suppressed by the raised oil pressure, so as to suppress the reverse rotation of the driving shaft 35.
