Title: Method for sputtering thin film
Inventor: NISHIOKA KOICHI
IPC: C23C14/34
Filed: 1988-04-28
Abstract: PURPOSE:To form a film reduced in the variance of composition by regulating the difference in electric potential between a film formed by means of sputtering and a plasma so that it is smaller than the lowest value among threshold voltage at which the sputterings of components are initiated, respectively. CONSTITUTION:A thin alloy film is formed on a substrate by means of sputtering. At this time, when Vs represents the electric potential of a film formed on a substrate by means of sputtering and also Vp means the electric potential of plasma, Vs and Vp are regulated so that they satisfy an inequality Vp-Vs<Vth (where Vth is the lowest value among threshold voltages at which the sputterings of respective elements as simple substances constituting the thin film are initiated). By this method, reverse sputtering can be prevented and the film reduced in the variance of composition can be obtained.

Title: Fuel feeding method in liquefied-petroleum-gas engine
Inventor: INOUE TETSUJI
IPC: F02M21/02
Filed: 1984-05-22
Abstract: PURPOSE:To make improvements in a rate of fuel consumption in time of steadiness as well as to improve accelerating performance, by detecting a variation in a throttle valve, while feeding a rich mixture to an engine in time of acceleration and a lean mixture instead in time of steadiness, respectively, in case of an LPG fuel feeder. CONSTITUTION:Liquefied petroleum gas in a tank 1 is fed to an engine 2 from a carburetor 9 after regulated for its supply by a control valve 8 via a primary decompression chamber 13, and a secondary decompression chamber 5. The control valve 8 is operated by c.w. or c.c.w. rotation of a step motor by means of the output of a controller 23 which inputs suction temperature 17, fuel temperature, opening and throttle variation of a throttle valve 19, inlet suction pressure 21 and engine speed 22. A fact that a variation in the throttle valve 19 in its opening direction is larger than the specified value is detected, thereby discriminating the engine to be in a state of being accelerated, and the valve 8 is opened, feeding a rich mixture. In time of the case other than that, the valve 8 is operated in its closing direction, feeding a lean mixture to the engine.

Title: Electric kettle
Inventor: NAKAZAWA RYOJI
IPC: A47J27/21
Filed: 1996-04-25
Abstract: PROBLEM TO BE SOLVED: To prevent steam and boiling water from flowing out at the time of returning to a normal position by providing a small pore, a very small pore and a valve element for closing the small pore when a main body is turned upside down inside a steam path for leading the steam to an outside and leading the steam inside a container through the very small pore to the outside when the small pore is closed by the valve element. SOLUTION: When the main body 1 is erroneously turned upside down, a water stop valve 18 closes a conducting port 19 and prevents the flow-out of hot water from a water pouring port 17 and the valve element 13 closes the small pore 10 and suppresses the flow-out of the hot water from a steam ejection hole 12. Since the diameter of the very small pore 11 is small, flowing out hot water is little. When the point of time of turning the main body 1 upside down is during boiling or when it is kept upside down for a long time, there is a case that internal pressure rises, and when the main body 1 is returned to the normal position in the state, there is the case that a conducting hole 19 is not opened and the steam path 7 is kept closed.  Since the steam inside the container 2 is released from the very small pore 11 by providing the very small pore 11, the steam inside the container 2 is released from the very small pare 11, the internal pressure inside the container 2 is rapidly lowered and the pouring amount of the hot water from the pouring port 17 is reduced.

Abstract: PURPOSE:To reduce the number of processes of mounting a cable and doing the resultant earthing work by constructing an insulating clamping member or a conductive member which is arranged in the internal circumference of the insulating clamping member in such a manner that the clamping member or the conductive member is elastically deformable in the radial direction thereof. CONSTITUTION:A clamping member 3 or a conductive member 5 is constructed to be elastically deformable in the radial direction thereof. The mutual electric connecting condition of the conductive part 2a of a member 2b being retained and the conductive member 5 is retained by push pressure derived from the clamping member 3 and by urged force derived from elastic deformation if the member 2b being retained is, for example, conductive. Meanwhile, such an external conductor as a conductive lead, or as a foil body or the like is connected to the connector-connecting portion 31 of the conductive member 5 so as to make electric connection of the conductive part 2a of the member 2b being retained to the external conductor. Besides, there may be no short circuit of a conductive body to the conductive part 2a of the member 2b being retained and to the conductive member 5 even if this conductive body contacts the clamping member 3 since the clamping member 3 has its insulating property. This may reduce the number of processes of mounting a cable onto a mounting sheet and doing the resultant earthing work.
