Title: Multichannel magnetic head
Inventor: ONO HIROAKI
IPC: G11B5/265
Filed: 1989-07-12
Abstract: PURPOSE:To prevent a tape touch defect, head clogging, etc., by radially disposing plural pieces of head chips formed with roundness equally on the right and left with a gap as a center onto one head base on the basis of a point nearly coinciding with the central point of a rotary drum mounted on the head base. CONSTITUTION:The plural head chips 1a, 1b, 1c are disposed onto one head base 2 radially from the point nearly coinciding with the central point of the rotary drum 9 to be mounted thereon. In addition, the respective heads are so stuck that the distance from the gap positions of the respective heads to the radial center are nearly equal and, therefore, the positions of the gaps 3a, 3b, 3c of the respective heads coincide nearly with the projecting center of the head. Since the round shape equal on the right and left is formed around the gap (there is no eccentric deviation in the roundness), the tape contact marks by long-term running are nearly equally formed on the right and left. The good tape touch is maintained over a long period of time in this way. Since the head chips are stuck to the head base only at the round shapes equal on the right and left with the gap as a center, the generation of a discontinuous surface on the head sliding surface is obviated and the sticking of dust, etc., to the head by such surface is lessened.

Title: Quantitative determination
Inventor: TAMURA MAMORU
IPC: A61B5/145
Filed: 1986-07-29
Abstract: PURPOSE:To enable quantitative measurement even when an object to be measured has a foreign matter possibly absorbing or scattering light beside a substance to be determined, by measuring changes in the absorbance of light with several wavelengths before and after the state of the object to be inspected changes. CONSTITUTION:Light with the intensity I0 is made incident on an object to be inspected such as living thing and the intensity I of the transmission light is measured to calculate absorbance A=logI0/I. Here, when a layer containing no desired substance in the object being inspected is represented by S, the desired substance in a tissue H containing the substance being represented by L and a remaining substrate left after the extraction of the desired substance L from the tissue H being represented by B, only the amount of the desired substance L in the object being inspected is varied to measure the absorbance again and thus, a variation DELTAA in the absorbance before the change is determined. A plurality of changes DELTAA are determined using lights with varying wavelengths to calculate the rate of change in the desired substance thereby enabling the quantitative determining of the desired substance L.

SOLUTION: A sealing cap 13 is mounted at both end parts of a porous pipe 10 in which a specified number of through holes 11 and 12 are arranged and a space is formed at a communication part 14 of the sealing cap 13 so that the plurality of through holes communicate therewith to make a closed space of a heat pipe. The inside of the hollow part thus obtained is evacuated and desired to seal a specified working fluid thereinto and the cross section of the through holes 11 is mostly made roughly multi-angular except for the through holes 12 located on both sides thereof 11 and 12 while being given an acute angle.  As compared with the normal through holes with a nearly rectangular or circular cross section, a clearance area narrow near the apex of the acute angle allows sufficient exertion of a capillary tube action on the working fluid thereby enabling the recirculation of the working fluid even in a top heat mode.

Title: Structure suppressing thermal deformation of structure member due to direct sunshine
Inventor: OGATA DAISUKE
IPC: H01Q1/12
Filed: 1989-07-11
Abstract: PURPOSE:To prevent a cover from flying away with a strong wind and to make the cover hard to be deformed with an external force by providing the cover with support legs as many as the divisions of the cover on the outer periphery of a structure member, tightening and fixing them to the structure member tightly, and providing a rib for reinforcement. CONSTITUTION:Heat radiated from the internal surface of the cover to the air between the azimuth angle AZ rotary structure part 4 and cover is removed by the flow of the air in the gap by a wind or the natural convection of the air in the gap, so the quantity of heat conducted to the AZ rotary structure part by the intervention of the air in the gap is extremely small. Therefore, the thermal deformation is reduced by suppressing the temperature rise of the AZ rotary structure part 4 low, and the adverse influence upon the direction accuracy of an antenna system can be reduced. Further, each cover section 10 has the support legs, contacting the AZ rotary structure part 4, fixed tightly with a bolt 11 and a band 12, so the load of the wind on the cover 10 is placed on the AZ rotary structure part 4, so that the cover never flies away even in the presence of a strong wind.
