Title: MOSFET and power conversion circuit
Inventor: DAISUKE ARAI
IPC: H01L29/772
Filed: 2017-11-02
Abstract: A MOSFET 100 according to the present invention includes: a semiconductor base substrate 110 having a super junction structure 117; and a gate electrode 12 6 formed on a first main surface side of the semiconductor base substrate 110 by way of a gate insulation film 124. In a graph where a depth x at a predetermined depth position in the super junction structure 117 is taken on an axis of abscissas, and an average positive charge density p (x) at the predetermined depth position in the 10 super junction structure 117 is taken on an axis of ordinates, the average positive charge density p(x) at a predetermined depth position of the super junction structure 117 when the super junction structure 117 is depleted by turning off the MOSFET is expressed by an upward convex curve projecting in a right upward direction. According to MOSFET 100 of the present invention, even when an irregularity exists in a charge balance around a gate, an irregularity in switching characteristics when the MOSFET is turned off can be decreased compared to a prior art.

Title: Sterilising pre-packed foods
IPC: A23L3/00
Filed: 1970-02-27
Abstract: Sterilising or pasteurising apparatus for foods packaged in glass bottles or cans has a treatment space through which passes a transporter provided with swingable carriers each consisting of a number of tubes with one permanently closed end placed in a circle, means for turning over the carriers, and a station for loading and unloading the carriers. Each of the carriers is provided at its non-permanently closed end with a closure plate placed on the carrier for rotation about the carrier axis between two positions, in the each of which the plate closes one of two different groups of containers, the plate closing both groups of containers in an intermediate position. The tubes of the two groups adjoin each other symmetrically in each carrier, and cooperate with a projection on the closure plate whose width corresponds with the radius of the tube. The closure plates prevent can ends from bulging out and becoming damaged during sterilisation. The plates can be easily moved for loading and unloading operations.

Title: Dewatering of slurry - by pressing between converging bands moving rapidly over rollers on a spiral path
IPC: B01D33/04
Filed: 1974-02-28
Abstract: A slurry is separated into two phases by pressing it between two continuous bands which move over rollers so that the liquid passes through the bands. The bands are relatively narrow and thin and move towards each other and are passed rapidly over a number of rollers on a spiral path. Slurry can be dewatered rapidly and continuously. The liquid is removed using centrifugal force and this gives a dryer product than usual. The liquid is not pressed back into the mass by the rollers.

Title: Water system with a pedal powered reciprocating pump
Inventor: ELLER JAMES DAVID
IPC: F04B9/14
Filed: 1999-10-15
Abstract: A water system includes a reciprocating pump operated by pedal power. The pumpstand includes a housing in which a foot pedal and a drive shaft rotate. An eccentric pin, rotating with the drive shaft, moves a connecting rod, which in turn causes a pushrod to oscillate vertically. The pushrod extends into a pressure-tight chamber formed above the rising main (wellpipe). A pumprod connected to the pushrod extends to move a conventional plunger through vertical oscillations. A flywheel is attached to the drive shaft, and a counterweight is mounted on the flywheel diametrically opposite the eccentric pin. The radial distance from the drive shaft to the counterweight can be adjusted. A discharge pipe extends from the pressure-tight chamber to an elevated or pressurized storage tank. A distribution pipe from the storage tank feeds water to a number of distribution points, such as faucets in houses.
Patent PT-80063-A (PT)
Title: Process for realizing energy saving operation in multipurpose agricultural buildings
IPC: A01G/
Filed: 1985-03-06
Abstract: For insulating and controlling the temperature of agricultural or horticulture buildings using thin walls incorporating non-transparent or transparent layers, a system is used which maintains the humidity and cleanliness of the surfaces with minimum heating. The heat content of the insulating space between two layers is increased by using heat radiation in a direction which is coplanar with the layers. Moisture is released in the space using an inside surface and the resulting water vapour absorbs the heat radiation. Energy is extracted from the layer of air by precipitation and drying. (First major country equivalent to PT--80063).
