Title: High-speed semiconductor device
Inventor: MUTO SHUNICHI
IPC: H01L21/338
Filed: 1986-06-19
Abstract: PURPOSE:To obtain a transistor at high speed utilizing an electron-hole pair superconducting mechanism by forming selective electrodes for a source and a drain to one of an electron layer and a hole layer adjacent through planar doping and controlling the concentration of carriers in the layer by a control electrode. CONSTITUTION:When an insulating AlAs thin-layer 4 is interposed between GaAs layers 1, 5 and an N-type impurity is introduced to a section 3 in the vicinity of the interface and a P-type impurity to a section 2 in the vicinity of the interface through planar doping respectively to shape an electron layer 3 or a hole layer 2, superconductivity is acquired at a low temperature by an electron-hole pair superconducting mechanism because two layers are separated by non-doped layers 11, 12 and the thin-layer 4. Only currents by electrons are extracted by selective electrodes 9, 10 for a source and a drian in order to obtain transistor operation. When the hole concentration of the hole layer 2 is increased previously, holes in the same number as the number of electrons of the electron layer 3 are brought to a superconductive state, and residual holes flow through paths in the hole layer 3 under a normal conductive state. Accordingly, the local storage of holes is reduced, thus preventing the inhibition of superconductivity.

Patent JP-S6125627-A (JP)
Title: Carbonating device
Inventor: ROBAATO POORU CHIYAIRUDO
IPC: B67D1/00
Filed: 1985-07-02
Abstract: Carbonating apparatus includes a reservoir (1) to be filled with fresh water through an outlet (2). Rotation of a control (9) opens a valve (3), so that water passes from the reservoir (1) into a pressure vessel (4). The control (9) is then depressed to cause pressurised gas to be introduced into the water in the vessel (4), via a nozzle (17), from a gas cylinder, so as to carbonate the water. A slidably-operable control (19) is then moved by an initial amount to cause a venting valve to open, thereby venting excess gas in the vessel (4) to atmosphere. Further sliding movement of the slidably-operable control (19) depresses a lever (35) connected to an outlet valve (24), which permits dispensing of the carbonated water from the vessel (4), via a spout (7).

Title: Gas burner for forced combustion
Inventor: AKAHORI YOSHIHIKO
IPC: F23D14/02
Filed: 1989-06-08
Abstract: PURPOSE:To stabilize the whole frame over the wide range of a load by making a low speed region wherein the flow velocity and flow rate of the air for a forced combustion are restricted adjacent to the flame forming portion of a burner and setting the air led to the low velocity region to the flow velocity and the flow rate at which the flame forming portion forms a diffused flame. CONSTITUTION:In a high load combustion, the air is not mixed with a gas led from a main flame opening 1 until the amount of the air reaches a combustion range even when the gas has been premixed with the air. However, since the air with the flow velocity and the flow rate restricted by restricting holes 5 is supplied to a low flow velocity region 3, part of the gas fed from the restricting holes 5 is burnt with the stable diffused flame in the low flow velocity region 3 to stabilize the flame of the main flame opening 1. In a low load combustion wherein the flame is formed only in the main flame opening 1, since the flow velocity near the main flame opening 1 is restricted, the stable combustion can be obtained, the flame is not sharp because of the mixing ratio of the air to the gas, flame opening portions is prevented from being overheated and a back fire can be prevented from being generated.
