Title: Magneto-optical recording medium
Inventor: NISHIKAWA KOICHIRO
IPC: G11B11/105
Filed: 1995-08-16
Abstract: PROBLEM TO BE SOLVED: To decrease the crosstalks at the time of signal reproduction with a land-and-groove magneto-optical recording medium for recording information on both of lands and grooves. SOLUTION: The ratio of a land width and groove width is deviated from 1:1. The magnitude of the deviation is set within the range meeting the phase difference tan<-1> (εk /θk ) which occurs on the light with a Kerr effect, where the Kerr ellipticity in the Kerr effect generated by photoirradiation is defined as εk and a Kerr rotating agle as θk . More particularly, the magnitude of the deviation described above is so set as to satisfy [ tan<-1> (εk /θk )}/2π].3.10<2> <=|R-50|<=[ tan<-1> (εk /θk )}/2π.6.10<2> , where [land width/(groove width + land width)].100 is defined as R. The magnitude is also so set as to satisfy |R-50|<=10 more preferably in terms of the level of reproduced signals.

Title: Airtightness tester for instrument fitted to wall surface
Inventor: NAKADA YAICHI
IPC: G01M3/26
Filed: 1985-09-24
Abstract: PURPOSE:To test simply airtightness of an instrument fitted to the wall surface by pressing a box body against the wall surface holding the instrument to be tested via an elastic airtight packing and detecting a rise of the inside pressure of the box body by a reduction of space of the inside of the box body. CONSTITUTION:An airtightness tester 10 has the box body 11 at one end of which an opening having a closed annular flange surrounding the instrument 2 fitted to the wall surface is formed and the elastic airtight packing 15 is fixed on the outside of the box body 11 of the annular flange. Further, a differential pressure gage 19 detecting the pressure difference between the inside and the outside of the box body 11 is fitted to the box body 11. Then, when the box body 11 is pressed against a wall 1, in a state that the packing 15 is brought into contact with the wall surface so as to surround the instrument 2, the packing 15 is contracted to the height S after the box body 11 is pressed from the height L before the box body 11 is pressed. Accordingly, the volume of inside space I of the box body 11 is reduced at a ratio of S/L. At this time, on condition that the contact between the wall surface and the packing 15 is airtight and the instrument 2 is airtight, a reduction of the volume brings about the rise of the inside pressure of the space I and as a result of the reduction ratio S/L of the volume, the rising ratio L/S of the pressure is obtained by the differential pressure gage 19.

Title: Flying erase head device
Inventor: TSUNODA KENJI
IPC: G11B5/53
Filed: 1985-09-24
Abstract: PURPOSE:To completely erase signals of all channels, by providing two flying erase heads at locations which are separated from each other with almost the same interval as that between the front head and rear head fitting locations. CONSTITUTION:Erase heads 30 and 32 respectively have such track widths that they can cover recording tracks of four channels and the interval between them is set equally to the interval between those at both sides of magnetic recording heads for four channels, namely, the interval A between the magnetic recording heads of the 1st and 4th channels. The erase head 30 is relatively moved across points (a) and (a') of a magnetic tape 10 and the other erase head 32 is moved across points (b) and (b') of the tape 10 and both of them erase signals. While each of the erase heads 30 and 32 can erase a half of the four channel area, the whole area of four channels can be erased, because each of them erases a different half area under an overlapped condition.

IPC: B23D36/00
Filed: 1987-08-25
Abstract: PURPOSE:To secure a constant length in cutting and improve yield and reduce troubles by installing a means for controlling the drive of a rotary cutting tool on the basis of the difference between a set length and a length measured by a length measuring means for a short material simultaneously with the cut of a long material. CONSTITUTION:In a cutting process, a calculation control part 10 detects that the top edge of a rod steel 1 passes through directly under the rotary cutting tools 4 and 5 and reaches a position S1 on the little passing side by a passing- side HMD 8, and a gate 11 is opened, and the pulse of a pulse generator 7 is counted by a counter 12 from the opening time, and it is detected from the marker signal of the generator 7 that the cutting tools 4 and 5 are set at the opposed positions.

Title: Preload variable spindle
Inventor: YONEYAMA HIROKI
IPC: B23B19/02
Filed: 1989-08-11
Abstract: PURPOSE:To uniformly provide a preload to bearings in accordance with the temperature change of a main spindle housing by circulating cooling fluid, whose temperature and flow rate have been controlled in accordance with the rotating speed, to the outer circumference of an outer-ring spacer, and also by circulating cooling fluid of room temperature to the outer circumference of a main shaft housing. CONSTITUTION:Cooling fluid of room temperature is circulated to outer cylinder cooling grooves 20 in the operating condition to restrain the thermal displacement of an outer cylinder 2. The distance L2 between the outer rings of bearings 3, 4 depends on the length of an outer-ring spacer 6, and cooling fluid is circulated to outer-ring spacer cooling grooves 15 by setting the temperature and flow rate in such a way that the outer-ring spacer 6 can be maintained at room temperature at the time of low-speed heavy-cutting, so that the temperature rise of the outer-ring spacer 6 due to heat generation can be prevented. When it is changed over to light-cutting high-speed rotation, the temperature and flow rate of the cooling fluid to be supplied to the outer-ring spacer cooling grooves 15 are changed over to the values which have been previously obtained on experiment in accordance with the rotating speed detecting signal of a spindle shaft 1 for preventing the increase in preload caused by the thermal expansion of the outer-ring spacer 6 due to high-speed rotation. When the length of the outer-ring spacer 6 is shortened than an initially set length by the intensified cooling of the outer-ring spacer 6 to produce a clearance between the spacer and the outer ring 3B, the outer ring 3B is elastically pressed by the energizing force of a spring 11 of a bolt 12 for fitting a front cover 8.

     CONSTITUTION: A surfactant and water are charged into a reactor, and an ethylenically unsatd. monomer [e.g. methyl (meth)acrylate or (meth)acrylic acid] and a polymn. initiator are slowly added to the reactor so that the ionic character in the reactor is kept constant. Thus, a free radical concn. in a stationary state can be obtd. during the monomer addition, enabling the particle formation to be completed and the monodispersity of the latex to be greately improved. Acrylic-based acids and esters are the most favorable, and copolymers contg. acids such as methacrylic acid are effective for producing latices for fibers. The surfactant is present pref. in an amt. of about 0.5-3 wt.% of the total amt. of monomers. The average particle size of the resultant polymer can be made to be 100 nm or lower, most favorably 10-20 nm.

Title: Heating device
Inventor: NAKAGAWA NAOHARU
IPC: F24H3/00
Filed: 1984-10-05
Abstract: PURPOSE:To improve the thermal efficiency by a method wherein a panel heater is arranged in a manner that the space between the panel heater and a wall is provided to be wide at the upper part and narrow at the lower part in a heating device provided with the panel heater. CONSTITUTION:A panel heater 5 is mounted on a wall 1 in inclined manner that the space at the upper part 6a between the panel heater 5 and the wall 1 is larger than that at the lower part 6b. By such a structure, an air moved upward due to the heating between the panel heater 5 and the wall 1 is contacted with a relatively lower temperature air located at the side part of the upper part 6a having a large space, then the temperature of the air moved upward is decreased. Meantime, the temperature dropping at the lower part is decreased due to the narrow space at the lower part 6b, accordingly, the temperature difference between the upper part and the lower part in the space formed by the panel heater 5 and the wall 1 can be decreased. Therefore, the power-OFF can be prevented in case that the temperature rising exceeds the limit of heat resistant temperature at the upper part in spite of the low temperature at the lower part of the panel heater 5. Thereby, the improvement of thermal efficiency can be contrived.
