Title: Thin film etching method and laminated thin film etching method
Inventor: MUKAI YUJI
IPC: H01L29/78
Filed: 1992-01-14
Abstract: PURPOSE:To form the cross section of a thin film into stepped form by a method wherein, after the thin film has been etched in the direction of film thickness using a resist film as mask material, the resist film is exposed to oxygen plasma and the like, and an etching treatment is conducted in film- thickness direction. CONSTITUTION:A resist film 16 is patterned on the thin film 4' formed on a substrate 1. Then, about half of the thin film 4, on the part which is not covered by the resist film 16, is etched in film thickness direction by wet etching. Then, the resist film 16 is exposed to oxygen plasma, the surface of the resist film 16 is removed by ashing, and the cross section is made small analogously. Further, the remaining part and the newly exposed thin film 4 is wet- etched. Subsequently, the resist film 16 is removed. As a result, the thin film 4 having step-like cross section can easily be obtained.

IPC: G06F12/08
Filed: 1984-01-13
Abstract: PURPOSE:To shorten the transfer time of track data and to improve the response performance of a rotary magnetic memory driver, by fetching data to a track buffer memory at and after the data on the sector which is detected first after the sector scan is started. CONSTITUTION:A buffer memory (track buffer memory 22) is provided for each track within a rotary memory controller 2, and each track of the memory 22 consists of plural sectors. In case a track 4i, for example, containing a sector which delivered a reading request to the controller 2 from a CPU does not exist in the memory 22, the data is transferred to the controller 2 from the track 4i of a rotary magnetic driver 3. In this case, the sectors are fetched successively to the address part of the memory 22 at and after a sector 5 which is detected first in the sector scan on the track 4i. Thus the revolving time of the driver 3 is set approximately at 0. This controller shortens the transfer time of track data and improves the response performance of the driver 3.

Title: Temperature detector
Inventor: KAWAMURA YOSHIHIRO
IPC: G01K11/12
Filed: 1980-01-23
Abstract: PURPOSE:To obtain a temperature detector having excellent insulation and tolerant to vibration while never affected by an electromagnetic field, by performing temperature detection by interrupting light led via an optical fiber by making use of the expansion and contraction of a fluid depending upon fluctuations of temperature. CONSTITUTION:Light from light source 1 is incident to one end of optical fiber 2 and led to temperature sensor 7. When the ambient temperature of temperature sensor 7 is low, the liquid level in temperature sensor 7 is lower than the position of optical fiber 2, allowing light to pass. Consequently, light emitted from the other end of optical fiber 2 is transmitted in transparent container 7b to strike one end of optical fiber 5, so that it will reach photodetector 6. Therefore, arrival of the light can be detected as an electric signal by the output of photodetector 6. When the ambinet temperature rises above a set temperature, liquid 7a in temperature sensor 7 expands to raise its liquid level and occlude the light from optical fiber 2, and consequently the light signal to photodetector 6 is cased and no output appears, so that the rise in temperature can be detected. Thus, the temperature detector or high performance can be obtained.
