Abstract: PURPOSE:To form a sidewall having enough thickness and length in a side part of a gate electrode and to enable implantation of impurity using the sidewall as a mask by forming an insulating film on a semiconductor substrate from above a resist pattern and a gate electrode and by thereafter removing the insulating film making a part formed in a side part of the resist pattern and the gate electrode remain by dry etching. CONSTITUTION:A metallic layer 11 is selectively removed by reactive ion etching using a resist pattern 15 as a mask to form a gate electrode 16. After an insulating film 17 is formed, the insulating film 17 is removed by reacted ion etching vertically to a surface of a semiconductor substrate 12 making a part formed at a side part of the resist pattern 15 and the gate electrode 16 remain. Through the etching, sidewall which consists of the insulating film 17 is formed at a side part of the resist pattern 15 and the gate electrode 16. A source region 18 and a drain region 20 are formed by implanting impurity ions into a semiconductor substrate 12 using a sidewall as a mask, which is thus formed of the gate electrode 16, the resist pattern 15 and the insulating film 17.

Title: Denitrated combustion device for pulverized coal
Inventor: MORITA SHIGEKI
IPC: F23C99/00
Filed: 1983-03-05
Abstract: PURPOSE:To provide a burner which can reduce the production of nitrogen compound without an increase in production of an unburnt content in combustion ash, by a method wherein fuel, fed to a central part from a main combustion zone, is gradually brought to a combustion condition, and NOX, produced at an external combustion zone, is reduced by combustion gas which includes a reduction active group produced due to air deficiency at the central part. CONSTITUTION:Pulverized coal is shortened in its flame through turbulent diffusion mixture with the air for combustion swirled by a swirling mechanism 35 to form a highly efficient flame which is burnt with high efficiency. High- power swirl is imparted to an entire flame A, and thereby a large amount of a recycling stream is produced in a direction extending toward a central axis from the tip of a burner flame. Thus, a small amount of pulverized coal discharged from the central part forms a jet B having a flow-through force with the aid of exhaust gas for carrying and collides with the recycling stream to form a decomposition range C of NO. In the range and a range C' illustrated, NO decomposition progresses with the aid of carbon hydride volatilized from pulverized coal fed by the jet B and a small amount of O2 fed from the flame range A together with NO.

IPC: H01L21/60
Filed: 1978-03-29
Abstract: PURPOSE: To prevent the probe tip from damaging the pellet and thus to ensure a quick and accurate execution of the test by forming a stage error at the ambient part approximate to the side of the function region of the bonding pad on the pellet.  
     CONSTITUTION: Stage error 3 is formed to function as the obstacle at the ambient part approximate to the side of the function region of bonding pad 2 formed on pellet 1. As a result, the tip of probe 4 has a shift toward the inside of the pellet from pad 2 when probe 4 of the test unit is pressed onto pad 2. Thus, probe 4 is drifted toward the function region to avoid cutting off the wiring. In this way, a quick and accurate test is ensured by fixing probe 4 onto pad 2 in an assured way.

IPC: B60N2/90
Filed: 1986-02-20
Abstract: PURPOSE:To delete the misalignment of right and left division seats by providing a seating detector for each seat and causing the monolithic motion of both seats when only one seat is used for sitting on. CONSTITUTION:When only one 4-division seat 'a' is used for sitting on and a switch for advancing the 4-division seats has been turned 'ON', a rail 7 becomes electrically live and a motor M1-4 turns, thereby advancing the seat 'a'. Consequently, a rail 9 becomes electrically live and a motor M1-6 turns, thereby advancing a 6-division seat 'b' as well. Thus, both seats 'a' and 'b' advance monolithically and stop at an advance end. Therefore, the position of the seat 'b' is always in line with the other seat 'a', thereby ensuring good appearance and eliminating refusing feeling.

Title: Stirling engine
Inventor: HARADA TERUMARU
IPC: F02G1/043
Filed: 1988-02-18
Abstract: PURPOSE:To protect a displacer rod from causing seizure because of the absence of solid lubricant applied to the rod, etc. which happened in the prior art by applying lubricant, such as oil, etc., filled in the space provided separately, to the gap between the displacer rod and a cylinder. CONSTITUTION:Displacer 18 of an engine moves vertically. This causes working fluid to reciprocate between a high temperature space 41 and a low temperature space 40, and to repeat being heated and cooled, and then generates pressure fluctuation, which reciprocates a piston 19, and thus the engine does work to a load 20. When the rod 21 moves vertically in matching relation with the displacer 18, bellows 25, 26, 29, 30 expand and contract so that the total volume of spaces 31, 32 does not change, as the spaces 31, 32 are filled up with oil. A small hole 42 is kept open to offset abnormal imbalance of liquid quantity between the spaces 31, 32. Furthermore, a gas spring space 38 is connected to a low temperature space 40 by high resistant flow passage 39, and this enables the respective mean pressures to be nearly the same.
