Title: Device for feeding core wire of electrode
Inventor: KUMADA TADAMORI
IPC: B23K35/40
Filed: 1986-12-20
Abstract: PURPOSE:To prevent the neck generation of an electrode by making the bearing part of a driving roller couple and umbrella type roller couple movable in the direction crossing with the core wire direction respectively and changing the contact position of the umbrella type roller by detecting the vibration of the driving roller as well. CONSTITUTION:At least one part of the bearing part of a driving roller 11 and umbrella type roller 8 is arranged by making it movable in the direction crossing with the progressing direction of a core wire 2. The position detector 58 of a bearing is provided at the vicinity of the end part of the driving roller 11 bearing part to detect the vibration generation of the driving roller and to input a signal to a control part 26 as well. When the feeding of the core wire 2 is delayed with the wear of the roller 8, the roller 11 starts to vibrate.

Title: Fan and casing of compressor
Inventor: CHIBA KAORU
IPC: F02K3/04
Filed: 1994-12-08
Abstract: PURPOSE: To suppress pressure loss and improve compression efficiency by arranging a circulation passage across a front half and rear half in a rotational area of a moving blade inside a casing, and suppressing formation of a peel-off area of a back surface of the moving blade. CONSTITUTION: In the case that a moving blade 10 is rotationally moved and relative flow near the moving blade 10 shows supersonic speed, air between the adjacent moving blades 10 is compressed due to generation of shock wave X and reduction of flow velocity. Air is compressed also by the rotation of the moving blades 10. A part of high pressure flow in a boundary layer behind the shock wave X is supplied to an inner surface of a casing 11 at a front position of the shock wave X. At a position near the leading end of the moving blade 10 where the peripheral speed shows a maximum value, a part of air flow passing a circulation passage 13 is added to its back surface. Peel-off phenomenon is suppressed and air flow is generated at a back surface of the moving blade 10. An inflow direction of air is stabilized accordingly, and pressure loss is reduced.

Title: Controller for air core instrument
Inventor: MOORISU RIDERU DANTSURAA
IPC: G01D13/22
Filed: 1989-11-24
Abstract: PURPOSE: To perform PWM current control of a coil accurately in a computer controlled two coil air-core instrument by an arrangement wherein a control signal determines the range of positive and negative coil current within a predetermined range of duty ratio and then it is further scaled to a specific range. CONSTITUTION: In the computer control of an air-core instrument, a controller processes input information to determine a desired displacement of a pointer and delivers a control signal to a bipolar driver. That signal is generated in the form of duty ratio of bipolar PWM. Positive and negative coil current ranges are determined at a duty ratio in the ranges of 0-50% and 50-100%. In order to eliminate the possibility of discontinuous generation of control signal, the duty ratio is scaled to Δ-(100-Δ)%. Δ is determined according to the input processing time of computer. According to the arrangement, discontinuity of the field vector of instrument is eliminated in zero area and the pointer is shifted by 360 deg. even if the duty ratio is not designated for 0-100%.

Title: Steam convection oven
Inventor: YAMADA YUTAKA
IPC: F24C1/00
Filed: 1995-11-01
Abstract: PROBLEM TO BE SOLVED: To reduce the steam which escapes from a heating chamber to the front when the door is opened during cooking by making a sliding door turn on its lower end, when the door is opened, in a manner of forming a gap for discharging steam between the upper end of the door and the heating chamber. SOLUTION: When the user opens the door 30, which is of the sliding type, a frontward pull at the handle 40 provided above causes the sliding door 30 to turn on a roller 38 at the lower end with the upper end 30A moved in the direction of the arrow (in diagram) and a gap 42 for discharging steam is formed between the door and the heating chamber 1. As a result, when steam is in use, the steam inside the heating chamber 1 is allowed to escape through the gap 42 gradually upward and flows out of the kitchen through a hood. The steam keeps escaping upward and is discharged as the user continues to pull the sliding door 30 upward along guide rails 32 by sliding. Since the sliding door 30 serves as a screen, the steam escaping toward the front of the heating chamber 1 can be reduced to a small amount.

Title: Ejection mechanism for floppy disk device
Inventor: SUZUKI AKIHIKO
IPC: G11B17/04
Filed: 1986-12-25
Abstract: PURPOSE:To protect a disk from being ejected by mistake by locking an ejector means of a ejection mechanism during the read/write operation of a floppy disk drive (FDD). CONSTITUTION:When a READY-signal is outputted from the FDD under the disk loading state, an ejector 18 is locked to be prohibited from moving according to an ejector locking signal I from a CPU 28. That is, when the FDD becomes ready for commencing its drive (under the starting condition for the read/write operation, inclusive of seek operation), the ejector 18 is locked so that the disk can not be ejected, even if an ejection button 13 is pushed. Consequently, the disk is never ejected at the time of read/write operation on this disk, even if the ejection button 13 is actuated by accident.

IPC: G11B5/66
Filed: 1987-12-07
Abstract: PURPOSE:To greatly improve the corrosion resistance and durability of a recording medium by providing a 1st protective layer consisting of B on a magnetic recording surface and providing a 2nd protective layer consisting of a (Co, Ni)1-xFex alloy film further on said layer. CONSTITUTION:The 1st protective layer consisting of the B or the alloy thereof is provided on the magnetic recording surface and the (Co, Ni)1-xFex alloy film (0<=x<=0.4) formed in gaseous oxygen is further formed as the 2nd protective layer thereon. This B film forms the dense film having good continuity even in the thin state and, therefore, the protective layer hardly allows permeation of corrosive gases and has the improved corrosion resistance. Since the (Co, Ni)1-xFex alloy film formed in the gaseous oxygen hardly adheres to metals and ferrite and has high hardness, the recording medium exhibits an excellent traveling property and sliding resistance and is greatly improved in the durability.
