Patent JP-H04286127-A (JP)
Title: Manufacture of insulated-gate field-effect transistor
Inventor: IZAWA TETSUO
IPC: H01L29/78
Filed: 1991-03-15
Abstract: PURPOSE:To eliminate easy arrival of dopant at a gate oxide film through a lower semiconductor layer by forming a gate electrode in a multilayer structure of a semiconductor layer of a lower layer and a semiconductor or metal layer of an upper layer, and interposing a layer insulating film having a diffusion blocking capacity between the layers of the electrode layers. CONSTITUTION:A substrate is heat treated by a RTA(Rapid Thermal Annealing) using a lamp. In this case, an SiO2 film 5 between thin gate layers is melted to disappear in upper first and lower second polycrystalline Si layers 4 and 5. Boron implanted in the layer 4 is diffused at once in the layer 4 to reach a gate oxide film 3, and a p<+> type polycrystalline Si gate electrode 10 is formed. Since the RTA is conducted in an extremely short time, the boron in the layer 4 does not pass through the gate oxide film and arrive at the surface of an n-type Si substrate 1.

Title: Treatment for waste liquid containing mercury by activated copper
Inventor: YAMAMOTO ATSUSHI
IPC: C02F1/62
Filed: 1980-04-15
Abstract: PURPOSE: To remove contained mercury inexpensively in a short time by controlling the liquid component after addition of copper salt and iron powder to waste liquid contg. mercury, and reducing under conditions of an acidic area followed by solid-liquid separation to alkalinity and filtering the same then neutralizing said liquid component.  
     CONSTITUTION: Copper salt is added to the waste liquid contg. mercury to control its pH to about 2W2.8, and after the liquid is agitated, iron powder and granules are added under agitation to allow copper amalgum to form on the surfaces of the iron powder, thence solids are removed by a solid-liquid separation method such as a magnetic separation method and further the liquid is filtered with filter paper No.5A. Thence, NaOH etc. are added to the 1st filtrate (2) to control its pH to about 10W11, after which it is filtered with filter paper No.5C, by which it is separated into the 2nd filtrate (3) and the 2nd residue (4). The 2nd filtrate (3) is  neutralized and is released. The 2nd residue (4) is dry distilled (7) and is fractionated to metal mercury (6) and the 3rd residue (5). The metal mercury (6) is recovered. Since the 3rd residue (5) contains Fe hydroxide, etc., it is preserved.

Abstract: PURPOSE: To find out the dimensions of the appropriate remaining part of a pipe even if the end face of the pipe is irregular, by detecting the rotated position of the pipe while sequentially measuring the inside diameter of the end of the rotating pipe, to control the displacement of an outside cutting tool.  
     CONSTITUTION: The reflected quantity of light emitted from a projector 10 and reflected on the end of a pipe 1 is detected by a photodiode 11 while the pipe 1 is being rotated, so that the inside diameter of the end of the pipe 1 is sequentially measured and the rotated position of the pipe is detected by a pipe's circumferential position measuring unit 5 made of a rotary encoder. The displacement (f) of a tool in each circumferential position of the pipe 1 is determined on the basis of the measured values and an appropriate remaining part dimension b o , a reference inside diameter a o  and a maximum tool displacement fMAX which are previously set by a setting panel 7. The determined displacement f is applied to a tool position controller to regulate a tool driver 9 comprising a rack and a pinion which is actuated by a servomotor.

IPC: A01N25/00
Filed: 1994-03-22
Abstract: PURPOSE:To obtain a herbicide containing, as active ingredient, a mineral oil such as spindle oil or heavy white oil, directly applicable by its dripping onto a paddy field filled with water, little affecting the environment such as water quality and soil, also excellent in terms of the cost. CONSTITUTION:This herbicide contains, as active ingredient, a mineral oil such as spindle oil, heavy white oil, light white oil, mineral spirit, mineral turpentine, naphthenic oil, paraffin oil or machine oil for agrochemicals. This herbicide is effective on all kinds of weeds developed in a paddy field (esp. on rice weeds such as Echinochloa crus-galli), being esp. effective at the initial growing stage of weeds being in a sunk state as a whole. For example, in the case of Echinochloa crus-galli, it is highly effective at the growing stage of two-leaf period or earlier, never affecting the growth of rice as a useful crop. It is preferable that this herbicide be applied esp. after rice transplanting. This herbicide, which floats on water surface, can be excluded by removing the upper surface of a paddy field after weeding.

Title: Closing lock device for fire door
Inventor: MATSUMOTO TAKESHI
IPC: E06B3/38
Filed: 1991-02-22
Abstract: PURPOSE:To ensure a fire door to be properly closed in the construction wherein the fire door holds a fitting energized in an open direction at a close position for preventing the spread of fire and smoke, upon occurrence of a fire. CONSTITUTION:When surrounding temperature rises due to a fire, the shape of an engagement body 10 fixed to a sash (fitting) 2 is restored to such an original memory shape as erects the end 10a at temperature lower than the heat resistance temperature of brackets 5 and 7. The erected end 10a of the engagement body 10 comes to be engaged with an window frame (frame) 1, thereby locking the sash 2 in such state as unable to oscillate in an open direction. The engagement body 10 has higher heat resistant temperature than those of the brackets 5 and 7 and, therefore, an outward open door (fire door) is kept locked in a close state, even if the brackets 5 and 7 deform due to a further temperature rise.

Abstract: PURPOSE:To reduce a generated magnetic flux of a write head by a bias magnetic flux portion, by providing a bias magnetic flux being below anti-magnetic force of a magnetic recording medium, in the direction opposite to the magnetizing direction of an erasing head. CONSTITUTION:When a tape 1 whose magnetizing direction is put in order in the direction as indicated with an arrow B after passing through an erasing head 2 is positioned between a write head 5 and a bias head 8, a bias magnetic field HB in the direction opposite to the direction of an erasing magnetic flux is provided to a gap 9 of the bias head 8. In this state, when a magnetic flux exceeding (anti-magnetic force-bias magnetic field) in the same direction as the magnetic field by the bias head 8 is generated by making a pulse current flow to a coil 7 of the write head 5, as a result, an external magnetic field exceeding anti-magnetic force is applied, the magnetizing direction is reversed,and the magnetization is executed in the direction as indicated with an arrow C. In this way, power saving can be realized by reducing write power, and also the reliability can be raised by reducing the calorific value.

Abstract: PURPOSE:To specify an input state during the conversion and to decrease the input mistakes by displaying both decided and undecided parts of conversion so as to distinguish them from each other for the KANA (Japanese syllabary) input of the Roman character/KANA conversion. CONSTITUTION:When a KANA character 5 is inputted in the Roman character/ KANA conversion with use of a keyboard 1 and a display 9, an input means 2 inputs the Roman character consisting of the alphabet via a keyboard 1 and transfers it to a conversion means 4. The means 4 converts the character string received from the means 2 into the KANA character 5 by reference to a Roman character/KANA conversion table 3. The produced character string of a decided part is displayed on a display 9 via a decided part display means 7 and a display means 8. At the same time, the character string of an undecided part is displayed on the display 9 via an undecided part display means 6 and the means 8. The means 6 displays the character string with inversion in order to distinguish it from the display carried out by the means 7. As a result, an input state is confirmed even in the course of conversion.
