Title: Thin film magnetic head
Inventor: TERUNUMA KOICHI
IPC: G11B5/39
Filed: 1997-05-16
Abstract: PROBLEM TO BE SOLVED: To provide a thin film magnetic head capable of displaying stable recording performance even when a recording track width is extremely narrow by making a crystal mean particle size in the vicinity of at least a recording gap layer of an upper part magnetic pole layer and the recording track width a specified quantitative relation. SOLUTION: A polycrystalline mean particle size of a part in contact with the recording gap layer 14 and the part placing in its vicinity among magnetic bodies constituting the upper part magnetic pole layer 15 is set equal to 1/20 or 1/20 or below of this magnetic head recording track width. Thus, the recording track width becomes extremely narrow, and even if it is a submicron order, dispersion in an overwrite characteristic, then, the dispersion in recording ability is reduced, and the stable recording performance is obtained. Although only the mean particle size of an upper part magnetic pole layer 15 side magnetic body polycrystal is considered now, it is a reason since a recording pattern on a magnetic medium is decided by the characteristic of the upper part magnetic pole layer 15, and particularly, since a composite type magnetic head is provided with a wide lower part magnetic pole layer 13 side width, isn't affected by a large particle size.

CONSTITUTION:A CVD gas supply system 9 supplies a mixed gas of SiH2Cl2, N2, and N2O gasses to a CVD cell 8 and an etching gas supply system 10 supplies a C2gas for etching, when these are applied to CVD of SiO2. A first pulse laser beam source 1 composed of an ArF excimer laser is used for exciting a CVD gas and a second pulse laser beam source 2 composed of an XeCl excimer laser is used for exciting Cl2 of the etching gas. Namely, a beam pulse for exciting the etching gas is projected by a shorter period than the time required for increasing the thickness of an thin film corresponding to one molecular layer. Consequently, impurities can be removed by an etching reaction before the impurities are taken into a CVD film.

Title: Dry etching method
Inventor: KADOMURA SHINGO
IPC: C23F4/00
Filed: 1986-06-19
Abstract: PURPOSE:To permit the shaping of the notched part of a groove bottom generated during the formation of a groove by adding a gas to generate a polymer to gaseous chlorine in a secondary stage at the time of etching a silicon substrate by gaseous chlorine. CONSTITUTION:The part of the substrate 1 which is not coated by a mask layer 2 is selectively etched by using the gaseous chlorine, for example, gaseous Cl2 at the time of etching the silicon substrate 1 formed with the mask layer 2. The deep groove 3 is thereby dug. The shape of the groove 3 formed in the above-mentioned manner generates the notched part 4 in the groove bottom 3a. The etching gas is then exchanged with the gaseous Cl2+CH2F2 contg. CH2F2 as the gas which can form the polymer to generate the polymer 5 in the groove 3. The polymer 5 sticks and deposits into the notched part 4. The etching progresses as the polymer 5 is sputtered out by the gaseous Cl2 at the flat surface of the groove bottom 3a, by which the groove bottom 3a is shaped.

Abstract: PURPOSE:To prevent the overheating within the dehumidifier so as to evade the rapture of a coolant pipe of a heat pump by providing thermally expansive expansion and contraction members which thermally expand under a high-temperature atmosphere to block an opening and contract under a low-temperature atmosphere to allow air passing through an opening to circulate. CONSTITUTION:A substance 11 (such as flon R113 or the like) which is in the form of a liquid at an ordinary temperature, is sealed in expansion and contraction members 8 and 9. During the operation of a dehumidifier utilizing a sauna chamber as a drying chamber, the ambient temperature of the dehumidifier A is a relatively low temperature close to the room temperature, and hence the substance 11 is a liquid as it is. During the operation of the sauna (the operation stop time of the dehumidifier A), the sub stance 11 contained in the expansion and contraction member 9 begins to evaporate in accordance with the rise in the temperature within the sauna chamber B, the pres sure within the expansion and contraction members 8 and 9 to expand to same, and adjacent members 8 and 9 are closely connected to each other to isolate the dehumidi fier A from the sauna chamber B to prevent high-temperature air within the sauna chamber B from flowing into the dehumidifier A. Thus, the coolant pipe of the heat pump within the dehumidifier A can be prevented from rupture.

IPC: H01L23/02
Filed: 1986-06-18
Abstract: PURPOSE:To realize an excellent finish plating on the surface of a metal shell, by a method wherein a cap is subjected to acid pickling with acid solution substantially of sulfuric acid and the finish plating is performed by applying a voltage on a metal shell. CONSTITUTION:A cap 1 is subjected to acid pickling in an acid solution substantially of sulfuric acid. This is based on that the low melting point glass 5 to fix a glass plate 4 on a metal shell 2 can hardly react chemically with a sulfuric acid, and the elution of lead component of the low melting point glass 5 hardly happens at the time of acid pickling. Applying a voltage on the metal shell 2 of the cap 1, nonelectrolytic plating is performed in order to make the nonelectrolytic plating on the surface of the metal shell 2 start, before the elution of the low melting point glass 5 into plating solution begins. As a result, finish plating on the surface of the metal shell of the cop can be uniformly performed with excellent quality.
