Title: Manufacture of semiconductor storage device
Inventor: OGAWA HISASHI
IPC: H01L27/10
Filed: 1991-09-13
Abstract: PURPOSE:To secure the electrical insulation between a bit line and an electric charge storage electrode even though the bit line is significantly exposed during the opening of a contact of the electric charge storage electrode due to a deviation in a lithography process. CONSTITUTION:An SiO2 film 2 is first formed on a p-type semiconductor substrate 1 by a LOCOS method. Thereafter, a switching transistor and a bit line 6 are formed. Then, for connecting an electric charge storage electrode 9 to a diffusion layer 7, anisotropic etching is performed using a resist pattern 7 as mask until part of the bit line is exposed from the first insulation film 3. Then, the resist pattern 7 is removed, the second insulation film 8 made of a high temperature oxide silicon film is deposited to 150nm, a side wall is formed by etching back the second insulation film 8 by the 30% over-etching relative to deposition film thickness, and then the bit line 6 can be electrically insulated from the electric charge storage electrode 9 with the sidewall of the second insulation film 8.

Title: Electroh beam lithography equipment
Inventor: KAGA HIROYASU
IPC: H01L21/30
Filed: 1986-10-03
Abstract: PURPOSE:To improve the accuracy of lithography by a method wherein an electrode pin and a grounding pin, which are arranged close to each other, are pressed against an insulating film on the surface of a wafer by means of an elastic material, the elastic material for the electrode pin is irradiated by a charged particle beam and the insulating film is destroyed by a point discharge so that the wafer and a cassette can be kept at the same potential. CONSTITUTION:An electrode pin 5 and a grounding pin 6, which are arranged close to each other at an insulating cup 4, are brought into contact with an oxide film 2 of a wafer 3 and are pressed against the oxide film 2 by means of springs 7, 8. If the spring 7 is irradiated by an electron beam 9, a high electric-field is generated at the tip due to an accumulated electric charge and this electric charge is discharged from the tip of the pin 5 to the tip of the pin 6. The oxide film 2 at the part between both tips is destroyed and, at the same time, the tips of the pins 5, 6 penetrate into the substrate of the wafer so that they can be brought into contact with the wafer surely. It is, therefore, possible to perfectly ground the wafer 3 where the insulating film 2 is formed on its surface. lt does not occur that the potential is changed due to the storage of incidence electrons inside the wafer 3. The accuracy for electron beam lithography, therefore, can be improved.

Filed: 1997-08-29
Abstract: PROBLEM TO BE SOLVED: To stably eject ink droplets regardless of a change in use environmental temp. by regulating the liquid level of the ink in an ink holding chamber so as to compensate the converging position of ultrasonic waves fluctuated by a change in peripheral temp. SOLUTION: A lid plate 18 provided with a circular opening part 19 is constituted of bimetals (metals 181, 182). That is, the bimetals (metals 181, 182) are constituted so that the lid plate is curved inside when temp. rises and curved outside when temp. drops. Now, the liquid level of ink can be moved by utilizing that the liquid level of the ink by the surface tension at the opening part 19 is held to move the lid plate 18 up and down in the periphery of the opening part 19. Therefore, by the above mentioned constitution, an ink jet recording apparatus 10 can regulate the liquid surface of the ink so as to compensate the fluctuations of the focal distance of a Flesnel acoustic lens 141 by the change of the peripheral temp. (the temp. change of an ink liquid 15).

Abstract: PURPOSE:To reduce the quantity of waste which is formed into a solid in a waste disposal process, by a method wherein a nitric acid collected from a nuclear fuel reprocessing process is led to an electrolytic cell and electrolysis is executed under the condition that the concentration of HNO3 in an electrolytic solution is not below 5M. CONSTITUTION:A direct current is supplied to an electrolytic cell 1 from a constant- current constant-volage device 2 and electrolysis is executed with platinum used as the material of an anode 11 and graphite as the material of a cathode 12. An electrolytic solution is made to circulate between the cell and a tank 4 by a circulation pump 3. A gas produced from the anode 11 is released in the tank 4, an N2 gas is supplied to the tank 4 and the produced gas is taken out. While the flow rate of the gas is measured by a flowmeter 5, the gas is diluted with the N2 gas and the composition and concentration of the gas are measured by an NOx meter 6. In order to produce an NOx gas selectively, the concentration of a nitric acid being an object of electrolysis needs to be selected at a high value of about 5 to 6 M or above. A scrubber 7 is provided in the preceding stage of release of the gas into the outdoor air and a water solution of Na2CO3 is stored therein.

Abstract: PURPOSE:To contrive miniaturization, reduction of cost, increase of reliability and obtaining of a high efficiency by a method wherein the increase of a drain voltage or the change of the voltage of a second secondary winding is given to a base, connected between gate sources through the series element of a capacitor and a resistor. CONSTITUTION:A differential circuit is constituted of a resistor 25 and a capacitor 26 and only the change of the drain voltage of a transistor 13 is applied on the base of another transistor 24. The transistor 24 absorbs a current, flowing through a parasitic capacitor 27, to suppress the increase of a voltage between gate sources. As a result, the transistor 13 continues the condition of OFF and a current flowing through the capacitor 26 and the resistor 25 is also blocked after the voltage of secondary winding 12 is stabilized whereby the transistor 24 is put OFF. When the polarity of the voltage of the secondary winding 12 is converted after a predetermined time has elapsed, the transistor 24 is put OFF by a reverse operation and energy is discharged to a smoothing capacitor 15 through a diode 14 parasitic on the secondary winding 12.

Title: Magnetic head
Inventor: HIMESHIMA KATSUYUKI
IPC: G11B5/127
Filed: 1987-09-18
Abstract: PURPOSE:To improve efficiency by giving two cores which face each other through a gap and setting the sectional areas of parts where magnetic fluxes crossing perpendicular to the coils of respective coils pass to equal. CONSTITUTION:When a=1.3mm and b=0.2-0.1mm in a present combination head, efficiency deteriorates by 10-15% compared to a head when a=b=1.6mm. For enlarging S2 for the prevention of the deterioration of efficiency, it is preferable to enlarge (b). But, it is impossible to enlarge (b) on the constructure of the combination head. When the thickness of the core is set to t1, and the thickness of the core 3 to t2, it comes to be S1=S2 even if a>b and it is set to t1/t2=b/a. Since the sectional areas of both cores become equal, the number of turns can be set to identical, and balanced turn can be executed, the quantity of the magnetic fluxes crossing with the coils of external conductive noise becomes same, and efficiency eta is improved, whereby an output is increased in a reproduction process.

Title: Transistor drive circuit of inverter
Inventor: HIRAMATSU AKINORI
IPC: H02M7/537
Filed: 1983-12-14
Abstract: PURPOSE:To quickly discharge stored carrier at ON time by inserting a reverse bias inductive impedance element between the base and the emitter of a transistor when the transistor is OFF. CONSTITUTION:When a transistor Tr3 is conducted ON, a current I is flowed to an inductive impedance element L1, a voltage V1 is applied between the terminals of the element L1, and electric energy is stored. When the transistor Tr3 is then turned OFF, an electromotive force to continue flowing a current I is generated in the element L1, and stored energy is discharged as a reverse bias current through between the base and the emitter of a main transistor TR1. Accordingly, the carrier stored in the base of the transistor at the ON time is forcibly discharged by the reverse bias current, and the storage time is shortened.
