Abstract: PURPOSE:To make the value of pinch-off voltage uniform by a method wherein a mesa etching is performed as deep as to the transition region located between a working layer and a buffer layer, and after the thickness of said working layer has been adjusted and made uniform, another mesa etching reaching the buffer layer is performed. CONSTITUTION:A mesa pattern 22 is formed on a GaAs wafer 21, an subsequently a mesa isolation process is performed by conducting an etching on a transition region (III) using a phosphate etchant. Then an SiO2 film 24, to be used as a spacer, is deposited on the whole surface. Subsequently, photoresist 25 is applied, a gate aperture part 251 is formed, and a power feeder aperture is provided. Then, an aperture part 241 is formed on the SiO2 film 24 using said photoresist 25 as a mask. Besides, an anodic oxidation is performed while light is being irradiated until the oxide film on the whole surface of the belt- formed part will be removed. Subsequently, an etching is performed on the working layer to the thickness which is good for a pinch-off voltage, and the pinch-off voltage is adjusted. Then, A1 is coated, a gate electrode 26 is formed, a mesa pattern is formed, the SiO2 film is removed, and then a mesa isolation process is conducted by performing an etching to obtain the thickness sufficiently reaching the buffer layer. Then, ohmic electrodes 17 and 18 are formed respectively, and a dig- in structure GaAsFET is obtained. As a result, the irregularity in the pinch-off voltage can be reduced.

IPC: A61G5/02
Filed: 1998-02-09
Abstract: PROBLEM TO BE SOLVED: To provide a wheelchair, which can be adjusted to physical shapes of growing children or users. SOLUTION: A seat rail 20, a seat 1 and a seat back 2 are made freely expandable in lateral and longitudinal directions and legs are made stretchable in the vertical direction. Large wheels 6 are also made detachable as a user is kept sitting on the wheelchair by shifting the load of the large wheels 6 to small wheels 7.

IPC: G02B6/12
Filed: 1989-03-31
Abstract: PURPOSE:To easily obtain the three-dimensional optical waveguides, etc., by adsorbing a dopant in a gaseous phase into the pores in porous glass controlled finely in a diffusion region. CONSTITUTION:The pores in the porous glass are previously positionally selectively closed 4, 5 by the polymer of a photopolymerizable compd. to limit the diffusion in a lateral direction. The porous glass is thereafter subjected to doping 6 by utilizing the multimolecular layer adsorption of the vapor of the dopant material to the pore surface of the porous glass. The porous glass is then rested in the atmosphere of the dopant partial pressure lower than the equil. pressure to partially desorb 7 the dopant. The dopant concn. of only the peripheral part of the glass is lowered to form a dopant concn. distribution 8 having the max. in the glass. The operation to fix the resulted dopant distribution in the form of an oxide into the pores is executed and further, sintering 9, 10 and pore elimination are executed, by which the desired optical waveguide parts 11 are formed in the glass. The three-dimensional (embedded type) optical waveguides are easily obtd. in this way.

Title: Coordinate detector
Inventor: SUZUKI TATEO
IPC: G06F3/041
Filed: 1986-04-07
Abstract: PURPOSE:To omit the double structure of coordinates in terms of a coordinate range and a display range and also to reduce the load of a computer system, by giving previously an optional adjustment to the position of the origin of the display range and performing a coordinate correction. CONSTITUTION:An operation indicates an original point 11 by a finger in the display range 9 of a display device and operates the knobs of the X and Y axis setting parts 12 and 13 to shift the point 11 for control of the point 11 to be coincident with the point indicated by the finger. In other words, the point 11 moved by an amount equivalent to the value controlled and shifted in the X and Y directions by both parts 12 and 13. Then the shift amount of the point 11 is registered to a coordinate correction part 14 and therefore the coincidence is secured between the point 11 of the range 9 and the original point in a coordinate range 7 of a coordinate detecting device. Then the operator indicates an optional point in the range 9 and an indicated point detecting part 4 sends the position data on the indicated point to a coordinate calculating part 5. While the shift amount of the original point set previously is already registered at the part 14 and therefore the part 5 obtains the coordinates of the indicated point. Then the shift amount of the original point is added to said coordinates to obtain the indicated coordinates of an optional point.

IPC: C21B13/02
Filed: 1988-03-31
Abstract: PURPOSE:To reduce unit consumption of carbonic material and production cost by additionally charging raw iron ore corresponding to excess carbonic material in pre- reduced raw material into a smelting reduction furnace at the time of producing molten iron by charging into the smelting reduction furnace after pre-reducing the iron ore by charging the mixed raw material of the iron ore, carbonic material and slag making agent into a pre-reduction furnace. CONSTITUTION:The mixed raw material of the iron ore, carbonic material and slag making agent is charged into the pre-reduction furnace 2, to execute pre-solid phase reduction to Fe2O3 in the iron ore. In this case, the excess carbonic material in the mixed raw material is blended to more than the necessary quantity to reduction in order to prevent sticking of the raw material. The raw iron quantity corresponding to the excess carbonic material in the pre-reduced raw material discharged from the pre-reduction furnace 2 is added and charged into the smelting reduction furnace 4. As the other method, the excess carbon material in the raw material discharged from the pre-reduction furnace 2 is sorted, removed and returned to the pre-reduction furnace 2 and the pre-reduced raw material containing no excess carbonic material is charged into the smelting reduction furnace 4. As the excess carbonic material is effectively utilized, the unit consumption of the carbonic material in this production line can be reduced and the production cost is reduced.

Filed: 1988-03-31
Abstract: PURPOSE:To obtain a high-quality printing, by detecting the lower end position of preceding lines, calculating an error amount of the detected position from the lower end position obtained in a proper paper feeding, and performing a correction paper feeding according to the error amount. CONSTITUTION:A CPU 11 shifts a carriage 31 and conducts a printing for one line on paper 33 by a printing head 21. While the carriage 31 returns to a printing start position, a sensor 22 scans the paper 33, which has been fed to a next line, in a carriage return direction. If the paper 33 is properly fed to the next line, detection signals are outputted from, for example, upper 4 elements 22a of 8 elements 22a forming the sensor 22. On the other hand, if a very little misregistration occurs, detection signals are outputted from the other range of the elements 22a. The CPU 11 calculates the error amount according to the comparison between the output state of the respective elements 22a and that of the respective elements 22a obtained in a proper feeding of the paper 33. Then, on the basis of the error amount the paper 33 is corrected to be fed to a proper printing position, and the printing for the appropriate one line is started.

Title: Protecting circuit for switching transistor
Inventor: ANTONIO BURAIDAA
IPC: H03K17/0812
Filed: 1983-05-04
Abstract: A protective circuit for a switching transistor is disclosed in which the base-emitter voltage of the switching transistor is compared in a comparator with a reference voltage. If the collector current of the switching transistor increases, the base-emitter voltage also increases, with the base current remaining constant. As soon as the base-emitter voltage exceeds the reference voltage, a signal is delivered at the output of the comparator. A switching-off device for switching off the driving pulses of the switching transistor responds to this signal so that a switching-on pulse present at the base of the switching transistor is switched off. The reference voltage is fixed so that the switching transistor is protected against overload by excessively large collector currents.
