Title: Schottky gate field effect transistor and manufacture thereof
Inventor: HAYASHI HIDEKI
IPC: H01L21/265
Filed: 1982-11-30
Abstract: PURPOSE:To reduce leaking currents due to the lateral dispersion of implanted ions and to reduce gate capacity, by performing slant ion implantations at the second time and the third time in order to reduce the resistances between a gate and a source and between the gate and a drain. CONSTITUTION:A first semiconductor crystal operating layer 22 is formed in a semiinsulating semiconductor crystal substrate 20 by selecting carrier concentration. With a stripe shaped mask pattern 21 as a mask, impurity ions, which have the same conductive type as that of the first operating layer, are implanted under the following conditions, at a dose amount of 1X10<13>dose/cm<2>, at implanting energy of 400keV, in a plane perpendicular to the direction of the stripe, and at a desired slant angle. The mask pattern 21 is removed, and a mask pattern 23 is formed. Ion implantation is performed at a desired angle, from the opposite side of the previous slant implanting direction. The pattern 23 is removed. A source 27 and a drain electrode 28 are formed on the slant implanting layer. A Schottky electrode 29 is formed on the conductive crystal so that the part corresponding to only the first semiconductor operating layer is completely coated.

Inventor: OE KENICHI
IPC: B21B37/00
Filed: 1991-08-22
Abstract: PURPOSE:To evaluate the temperature at a necessary position in the direction of a plate thickness by predicting not only an average temperature but also the temperature distribution in the thickness direction of a steel plate through a simple calculation with high accuracy concerning a method for predicting the rolling temperature of a hot rolled stock such as a TMCP steel plate, etc., on line in the rolling process. CONSTITUTION:A 1st temperature distribution in the thickness direction of a steel sheet controlled only by the cooling mode of rolling process and a 2nd temperature distribution in the thickness direction of the steel sheet showing a recuperative behavior of heat in the steel sheet are intended to be obtained respectively as a boundary value problem of an initial value derived of simultaneous partial differential equations based on a heat contuction equation. For that purpose, a weak expression from is used for these simultaneous partial differential equations and these simultaneous partial differential equations results in the simultaneous ordinary differential equation series of time. The simultaneous ordinary differential equations are solved to find the 1st and 2nd temperature distributions, the predictive model of an on-line rolling temperature at a temperature field formed when the steel sheet having a prescribed initial temperature distribution is cooled under a specified cooling mode is created by combining the 1st temperature distribution and the 2nd temperature distribution and the rolling temperature in the thickness direction of the steel sheet in the rolling process is predicted in accordance with this model.

Abstract: PROBLEM TO BE SOLVED: To make it possible to shorten the time required for layout work at the time of reticle formation and to simplify the work by automatically adding or deleting adequate modification patterns to angle parts, thereby forming the patterns of the adequate reticle. SOLUTION: The patterns of the reticle are divided to microdots of a square shape or the rectangular shape conforming thereto at a length of 1/5000 based on design rule in length on one side.

For example, dots D, L and LL exist as the dots adjacent to a dot a1 in question. Here, the modification patterns in the overhanging shape of the rectangular shape of the size up to the dot a1000 of the 1000th order are added along the side of the dot a1 in the case of the size of the dot at 1/5000 of the design rule.

Abstract: PURPOSE:To reduce noise without causing the lowering of storability and handleability owing to the enlargement of a cleaner main body, by providing each wheel, on which rear surface a sound-absorbing material is stuck, provided on the cleaner main body and each exhaust port, which faces the wheel and is on the side wall of the cleaner main body. CONSTITUTION:When a fan motor 6 is started, air containing dust is sucked with a floor nozzle 1, and is sent to a dust-collecting filter 4 in a cleaner main body 3 through a dust-collecting hose 2. After the dust and the air are respectively separated, the dust stays in the dust-collecting filter 4 and the air flows in a suction opening 10 for the fan motor 6 through an air-passing opening formed on a partition plate 15, following which the air cools a driving motor 7 and is exhausted from exhaust ports 9. The air exhausted is led into a pathway formed between the inner wall of the main body 3 and the outer wall of a noise-proof cylinder through the noise-proof cylinder and exhaust ports 35a, 35b, and is exhausted to the outside of the cleaner through exhaust ports 32a, 32b on the main body. After sound in exhaust with noise is absorbed with both a sound-absorbing material 36 and sound filters 37a, 37b, the sound collides with another sound-absorbing material stuck on the rear surface of each wheel, and is absorbed again.

Title: Nonaqueous electrolyte battery
Inventor: KUSUMOTO YASUYUKI
IPC: H01M10/05
Filed: 1997-08-05
Abstract: PROBLEM TO BE SOLVED: To provide an electrolyte which restrains self-discharge when a battery is preserved and whose preserving characteristic is improved by including a specific quantity of dioxolane in an organic solvent containing oxygen acid ester. SOLUTION: At least one kind of oxygen acid ester selected from a group of phosphoric ester, boric acid ester and titanic acid ester is included in an organic solvent containing dioxolane >=10 wt.%. When a nonaqueous electrolyte composed of this organic solvent and a solute is used, the oxygen acid ester reacts with lithium in the presence of dioxolane to form a good quality coating film on a negative electrode. Since this coating film restrains direct contact of lithium with the solvent, the decomposition of the nonaqueous electrolyte is restrained. Trimethyl phosphate is thought to easily form an optimal coating film on the negative electrode or to be easily attracted on the negative electrode in the oxygen acid ester, and a self-discharge rate is further restrained.
