Title: Reactor device
Inventor: KISHIMOTO FUKUTAROU
IPC: H01F27/33
Filed: 1978-11-29
Abstract: PURPOSE: To suppress vibration sound from a reactor, in spite of simple construction, by disposing frame members charged with damping material for vibration on peripheral walls of a tank accomodating a reactor to form double walls by use of the frame members and the tank.  
     CONSTITUTION: A reactor is accommodated in a tank formed by an outer wall plate 2 which is reinforced by longitudinal and lateral frames 3a and 3b. Formed on the upper plane of the frames 3a and 3b are pots 5 for pouring a damping material 6 for vibration into spaces formed by the outer wall plate 2 and the frames 3a, 3b. Thus, the vibration generated from the reactor accommodated within the tank is absorbed by the stress of damping material 6 to reduce the expansion and contraction of the reinforcing frames 3a and 3b, and the transmission of vibration sound to the outside of the tank is thereby prevented.

Title: Display controller in graphic display system
Inventor: HIMENO TOMOHISA
IPC: G09G5/36
Filed: 1994-06-07
Abstract: PURPOSE:To plainly display graphic on a display device by switching over first and second modes by a mode switching means to select whether coordinate conversion of attributes should be executed or not. CONSTITUTION:When icon zoom is designated with a mouse 18, coordinate conversion of attributes is not executed and only coordinate points of graphics are expanded by conversion because the conversion mode is initialized to non- conversion at this time. When icon redisplay is designated by the mouse 18, the same graphics are displayed again because the conversion mode is initialized to non-conversion. When icon conversion/non-conversion is designated with the mouse 18 to switch over the conversion mode to conversion execution, graphics obtained by coordinate conversion of attributes are displayed. When icon zoom is designated with the mouse 18, coordinate points of graphics are expanded by conversion and are displayed, and coordinate conversion of even attributes is executed because the conversion mode is set to conversion.

Abstract: PURPOSE: To prevent variation of the element characteristics by oxidizing the boron silicide at 500W800°C after removal of the B 2 O 3  film.  
     CONSTITUTION: B 2 O 2 4, boron silicide 5 and high-density B layer 6 are formed on p-type substrate 1's n-layer 2 through the heat diffusion. Film 4 is removed and the oxidation is given by flowing O 2  with 1W2l/min. for 10W60 min. and at low temperatures of 500W800°C. Then Si oxide film 7 is ethced and heated up to diffuse B in layer 6. Thus, layer 7 is formed, causing SiO 2 8. In this way, the boron silicide, which causes the B desity dispersion in formation of the diffusion layer, is oxidized at the comparatively low temperatures. As a result, the crystal defect, the B diffusion progress of oxidation of layer 6 itself can be prevented, thus causing no deterioration of the element charactristics.

Title: Manufacture of semiconductor device
Inventor: KODAMA KUNIHIKO
IPC: H01L29/812
Filed: 1981-09-22
Abstract: PURPOSE:To prevent the breakdown of an FET which is produced by the breakdown of a boundary between an operating layer and a high resistance layer by doping doner impurity on part of the high resistance layer. CONSTITUTION:Doner impurity is doped in the vicinity 7 of the position corresponding to the gate electrode 2 of a buffer layer or a semi-insulating layer 6. Thereafter, an operating layer 5, a source electrode 1, a gate electrode 3 and a drain electrode 3 are formed. As a result, since the gradient of a depletion layer 4' becomes smooth, the electric field intensity becomes weak in the region A that the electric field is the highest in the operating layer as compared with the conventional device, while the length of the region A becomes long. Accordingly, since the ultrafine current which flows through the layer 6 flows through the region of the layer 6 in the wider range than the conventional device, the resistance in this region increases. Accordingly, the electric field in the boundary B can be reduced.

Abstract: PURPOSE:To always perform optimum communication by providing a means in which communication parameters are stored for each destination, a means which detects and discriminates error at the time of the occurrence of communication abnormality, and a means which sets a communication parameter in accordance with the error detection result. CONSTITUTION:A means 18 in which communication parameters are stored for each destination, a means 17 which detects and discriminates error at the time of the occurrence of communication abnormality, and a means 15 which sets a communication parameter in accordance with the error detection result are provided. When error occurs during transmission, the error detecting part 17 discriminates the classification of error, and the classification of the destination terminal in a destination management file 21 is updated in the communication parameter storage part 18 if error is caused by disaccord of terminals.

An equipment itself automatically performs such control that optimum communication is performed when an operator performs the operation without paying his attention to the function of the destination terminal. Thus, the number of failures in communication is reduced to shorten the unnecessary communication time.
