Title: Oil-water separation apparatus utilizing lp gas as absorbent
Inventor: KADOTA MORIYOSHI
IPC: B01D17/02
Filed: 1983-04-06
Abstract: PURPOSE:To recover the oil content in water by utilizing the property of a liquefied petroleum gas which well absorbs oil and has a lighter sp. gr. than water. CONSTITUTION:When a liquefied petroleum gas is introduced into a pressure vessel, a gas part C and a liquid part D are formed, and the pressure of the vessel becomes the saturated vapor pressure of the LP gas. When a mixture of water and oil is forced into the vessel by a pump, a closing valve 1 is opened, and the mixture falls like a shower from a nozzle 5, passes through the liquid D of the liquefied LP gas, and accumulates at the lower part of the LP gas. While passing through the liquid D of the LP gas, the oil content on the surface of the water droplet is absorbed in the liquid of the LP gas. In addition, the oil content in water accumulated at the lower part floats up to the water surface due to the light sp. gr., and is absorbed in the liquid of the LP gas. When the internal pressure is increased due to the increased inflow of the water, a pressure closing valve is opened, and the water is discharged. When the oil concn. in the liquid of the LP gas is increased, the liquid of the LP gas is returned to another vessel after discharging the water.

Title: Switching power source
Inventor: YUGAWA NAOTOSHI
IPC: H02M3/28
Filed: 1998-03-12
Abstract: PROBLEM TO BE SOLVED: To control a switching power source so that its output voltage falls within the allowable error range of its rated output voltage, even when the load of the power source is light. SOLUTION: A switching power source is constituted in such a way that the voltage induced in the secondary winding NS of a choke transformer L for storing electromagnetic energy is always monitored on an average at a capacitor C2 via a diode D3 , by considering that the voltage is proportional to the output current IOUT fed to a load, but, when the output current IOUT is considerably small due to the lightness of the load, an appropriately large load current (i) is forcibly made to flow to a dummy load R2 via a transistor Q2 is a pseudo-executing way, while the smallness of the current IOUT is detected by means of a resistor R1 and the transistor Q2 .

Title: Manufacture of semiconductor device
Inventor: MIKATA YUICHI
IPC: H01L21/316
Filed: 1985-03-26
Abstract: PURPOSE:To reduce a production density of OSF by a method wherein a semiconductor substrate is oxidized in an oxidizing atmosphere containing oxygen to form a thermal oxide film with a thickness of not less than 40nm and then continually oxidized in another oxidizing atmosphere containing vapor to form a thermal oxide film with a thickness of not less than 100nm. CONSTITUTION:A thermal oxide film with a thickness of not less than 40nm is formed by the oxidization in an oxidizing atmosphere containing oxygen in the initial stage of an oxidizing process. If the thickness of the formed thermal oxide film is less than 40nm, a production density of OSF is not so much different from that obtained by the oxidization in an oxidizing atmosphere containing vapor only. As the atmosphere of the initial stage of the oxidizing process is different from that of the latter stage, the production density of OSF is reduced and the thermal oxide film with the thickness of not less than 100nm can be formed without reducing a through-put so much.

Abstract: PURPOSE:To prevent a sheet from being contaminated with an ink, by a construction wherein a recording head is fitted to a head support member oscillated with a vertical shaft provided on a carriage as a center so that an ink ribbon is prevented from slipping when the head is brought into close contact with the sheet. CONSTITUTION:A supporting part R1 of a pulley 21 for an ink ribbon 7 is located on the axes of a head support member 17 and a releasing member 29 (which are coaxial with each other), and a take-up side ribbon core 23 is not moved without being rotated. Therefore, by turning the members 17, 29 together immediately before bringing a recording head 15 into contact with a platen 2, the length of the ink ribbon 7 on the take-up side (the downstream side of the head 15), i.e., the ink ribbon length from the point R1 through a shaft 30 to a point R3 is maintained constant until the head 15 comes into contact with the platen 2. Accordingly, the ribbon 7 and a sheet 1 do not make frictional contact with each other when the head 15 is pressed, and the sheet 1 can be prevented from being contaminated.

Abstract: PURPOSE:To enable reliable catching of a huge boulder, by mounting a fluid cylinder operating mechanism to an opening and shutting mechanism of a weight type clamshell for a title device for drawing up a boulder in an excavation hole. CONSTITUTION:If a Kelly wire, hanging a boulder removing device body 1 through the medium of a Kelly bar 26, is rapidly loosened to drop it, a weight 8 drops downward through an inertia power to feed fluid in a cylinder 6 by pressure to a cylinder 7 and an accumulator 17 through a non-return valve 18. Fluid, fed by pressure to the cylinder 7, raises a rod 7', and as a result, a transmission rod 9, opening and shutting a clamshell 2 pivotably secured to the lower end of the device body 1, is raised to forcibly close a clamshell bucket. This causes exerting of shock of the inertia power of the weight on a boulder, and simultaneously, the inertia power of the weight is converted into the closing force of the clamshell.
