Abstract: PURPOSE:To facilitate the control of forming a recess of the shape gradually widened in width in depthwise direction and gradually narrowed from the midway without using a sulfuric acid etchant by using an etchant which contains phosphoric acid + hydrogen peroxide + tartaric acid. CONSTITUTION:The recess 4 of a field-effect transistor formed with a gate electrode 5a in the recess 4 formed by digging the surface of a GaAs substrate is formed by etching with an etchant containing phosphoric acid + hydrogen peroxide + tartaric acid. For example, an N<-> type buffer layer 2 and an N-type operation layer 3 are epitaxially grown on a semi-insulating GaAs substrate 1 to form a source electrode 6 and a drain electrode 7. Then, the width of a gate electrode is opened by coating it with a resist 8, and the recess 4 is formed by etching with the etchant containing phosphoric acid + hydrogen peroxide + tartaric acid. Thereafter, Schottky metal 5 such as aluminum is deposited to form a gate electrode 5a in the recess 4, and the resist 8 and an unnecessary metal 5 are removed to complete an FET.

Title: Method and device for reproducing optical information
Inventor: MIYAMOTO JIICHI
IPC: G11B7/24085
Filed: 1989-04-10
Abstract: PURPOSE:To perform the high speed and high density information reproducing without cross talk by containing more than two bits of information in a light spot and utilizing a change of reflecting light in distribution of its spacious strength. CONSTITUTION:The reflecting light of the spot 3 of a laser 2 on a recording medium 1 is converged via a splitter 8 onto a multisected detector 6. When the presence of recording pits 4 in the spot 3 is detected by, for instance, a tetrasected detector to be arithmetically processed, the original recording information is restored. Since bits of information are reproduced from plural recording pits 4 by the spot 3, the high density information can be reproduced without being controlled by the spot in size, and then since it is essentially a multiple text system, an information transfer speed is large, while since surrounding information is simultaneously detected, misread (cross talk) due to adjacent information is essentially not jeopardized, the high densification thus is achieved by arranging the recording information compactly on the medium 1.

IPC: G06F12/08
Filed: 1987-04-10
Abstract: PURPOSE:To minimize adverse influence despite the switching of program modules or operating systems OS in case these modules or OS are run, by dividing an address conversion buffer into plural sections and giving the priority for allocation of these sections. CONSTITUTION:An address conversion buffer 3 is divided into plural areas #0-#n and plural program modules or OS are run. Under such conditions, at least one area is allocated with preference for storage of address conversion information on a specific program module or OS. When write/read operations are carried out with the buffer 3, the section number of the program module or OS which is set under a running state is held and access is given to the corresponding section only so that no disturbance is given to other section. Thus the relevant address conversion information remains on the buffer 3 in case a switched program module or OS is dispatched again to a specific program module or OS.

Title: Expiration/inspiration sensor for human being and animal
Inventor: KATADA HIROYUKI
IPC: A61B5/08
Filed: 1990-04-03
Abstract: PURPOSE:To detect the state of expiration and inspiration in a natural state by converting a physical variation of a temperature difference and a humidity difference of expiration and inspiration at the time when a human being and an animal breathe into an electric signal and outputting it by using an element in which potential is varied due to a variation of a temperature and humidity in an entrance of a nostril. CONSTITUTION:In a sensor 1 installed in a nostril of a human being and an animal, in an expiration state, a temperature of the sensor 1 rises by expiration containing much moisture being near the body temperature and the surface of the sensor 1 is dewed and gets wet. Subsequently, even if breathing is stopped, as for the sensor 1, the temperature does not fall due to the influence of the body temperature. Next, at the time of becoming an inspiration state, the open air which is lower than the body temperature or whose humidity is lower than that of expiration passes through the sensor 1 and heat of vaporization is deprived, the temperature of the sensor 1 falls suddenly and the output potential is varied suddenly. By the variation of this output potential, output signals from an integrator A of an amplifier and a differential amplifier B are amplified and outputted by an amplifier C. Subsequently, when inspiration is executed as it is, the output signal is generated only for a time constant time of an integrator B.
