Title: Semiconductor memory device
Inventor: KOYANAGI MITSUMASA
IPC: H01L27/04
Filed: 1983-12-02
Abstract: PURPOSE:To expand an operating margin, and to improve the degree of integration by forming the storage capacitance of a memory cell by an n<+> layer-an insulating film-a poly Si layer and selecting a material for the insulating film from Si3N4, Al2O3 or Ta2O3. CONSTITUTION:n<+>-Layers 8, 9 are formed to the surface of a p type Si substrate 1 isolated by a field oxide film 2, the layers 8, 9 are coated with the Si3N4 film 3 and an SiO2 film 4, P added poly Si layers 6, 7 are formed selectively through an inter-layer insulating film, the layers 6, 7 are coated with PSG 10, and an Al electrode 11 is attached. Storage capacitance is formed by the poly Si 6-the Si3N4 film 3-the n<+> layer 8 at that time. Consequently, when a film of high permittivity is used as the insulating film 3, the area of a memory can be reduced, and the device can be made difficult to be affected by alpha-rays. The gate electrode 6 can be grounded by changing the surface of the substrate, to which the film 3 is formed, into an n<+> shape, and the instability of the reading and writing of the memory cell due to the interface order of the insulating film and an Si interface and the influence due to a trap can be removed.

Inventor: YAMANE HIROSATO
IPC: B22D11/16
Filed: 1990-08-29
Abstract: PURPOSE:To shorten width changing time for continuously cast slab by keeping deformation of the cast slab in the range of permissible strain while developing no air gap at any position between short side and the cast slab. CONSTITUTION:The width of cast slab 4 is changed by shifting the short side 1a in the mold at the time of continuous casting. Then, at the time of enlarging the casting width, shifting velocity of the short side 1a is made to have interval changing the width with the shifting velocity of meniscus part at the short side and keep the deformation of short side 1a and cast slab 4 in the range of permissible strain. The shifting velocity of short side is made to satisfy the inequality I and the inequality II. In both inequalities, Vu(f): shifting velocity of meniscus part at short side, Vl(f): shifting velocity of lower end of short side, V(c): casting velocity, lm: distance between mold meniscus part and lower end in mold, T(t): tapered rate of short side in mold, theta1: permissible strain, phi: deformation allowance at meniscus part, t: time. By this method, length of the width changing part to the cast slab can be shortened.

Title: Petroleum combustion device
Inventor: TOMITA HIDEO
IPC: F23D11/44
Filed: 1990-08-28
Abstract: PURPOSE:To provide a petroleum combustion device capable of keeping a gasification capability and preventing a thermal strain at a heat accepting part by a method wherein a heat accepting part composed of heat accepting fins is provided to have a wider heat accepting area at an outer wall at a lower part of a gasification chamber and near a striking part to which fuel in the gasification chamber is injected and further to have a narrow heat accepting area other than near the striking part. CONSTITUTION:Near a striking part 10, a large amount of gasification latent heat is removed by keroscene as compared with that 11 other than near the striking part and this part is air cooled with gasified air. In turn, since the part near the striking part 10 stores a close part of a heater 9, an amount of accepted heat from the heater 9 is naturally increased as compared with that 11 other than the striking part storing a rough part of the heater 9. The part near the striking part 10 has a heat accepting part 17 having a wider heat accepting area, so that a heat accepting amount of combustion heat is increased as compared with that 1 other than the striking part having a heat receiving part 17 with a narrow heat accepting area. As a result of this thermal balance, the part near the striking part 10 can accommodate for a large amount of gasification latent amount of heat from a heater 9 and a heat accepting part 17, so that a temperature near the striking part 10 is kept and the gasification capability can be maintained. The heat accepting part 17 near the striking part 10 accepts a large amount of combustion heat. Since a large amount of heat is transferred near the striking part 10, a temperature increasing is restricted. Accordingly, it is possible to prevent a thermal strain at the heat accepting part 17 or the gasification chamber 5.

IPC: B41J2/305
Filed: 1984-10-29
Abstract: PURPOSE:To make possible a stable printing to be carried out by forming an electrode provided oppositely to a needle with a taper being made thinner toward the needle. CONSTITUTION:The electrode 9 provided oppositely to a needle 5 is formed with a sloping surface 10 such that the facing side to the needle 5 is made thinner, and its tip is made as a narrow opposition surface 11. In such a construction, the flying direction of the ink 13 is directed to the opposition surface 11 of the electrode 9, though a relative position between the needle 5 and the electrode 9 is shifted more or less, the displacement of a dot forming position is small, since the lines of electric power are concentrated between the needle 5 and the electrode 9, and to the opposition surface 11 in the electrode 9 section especially. Therefore, an exact printing can be carried out.

Title: Polarization independent type optical isolator
Inventor: FURUKATA YUKIKO
IPC: G02B27/28
Filed: 1994-09-22
Abstract: PURPOSE: To make polarization dispersion zero and to enable optical communication for a long distance at a high-speed and high density without generating the waveform distortions of signal light pulses by disposing double refractive materials such as double refraction plates varying in pass speeds in directions of planes of polarization. CONSTITUTION: The double refraction plate 5 which is the double refractive material compensates the delay time difference generated within this polarization independent optical isolator by setting the pass speed of the signal light pulses which are later incident light higher than the pass speed of previously incident signal light pulses by utilizing the difference in the pass speeds in the directions of the planes of polarization. Parallel flat plates of rutile crystal plates are used as the double refractive plate 5. The rutile crystal plates have the highest double refractiveness and are formed by cutting out the crystal to parallel the incident surface with the c-axis in such a manner that the rays are not separated. The crystal plates are adjusted around the Z-axis to attain such a direction where the light beam f1 is made to an abnormal light component. Since the delay time difference is made zero, the polarization dispersion is made zero. The optical communication at the high speed and high density is thus made possible.
