Title: Hot-water heating machine
Inventor: SAKAI KUNIO
IPC: F24H1/24
Filed: 1979-04-25
Abstract: PURPOSE: To stabilize temperature and remove the bubbles of dissolving oxygen completely by a mechanism wherein a hot-water supply pipe, which has an opening portion in a heat exchanger, is disposed just under an air valve mounted to an upper portion of the heat exchanger and hot water to be supplied is flowed out to a lower portion from an upper layer.  
     CONSTITUTION: Bubbles formed in a heat exchanger 2 float to an upper portion by buoyancy and are collected by means of an air vent valve 4; heated hot water to be supplied is downward transferred in a hot-water supply pipe 5. Consequently, the bubbles formed in hot water to be supplied are completely separated while heated hot water to be supplied at an upper layer flows in from an opening portion 5a of the hot-water supply pipe 5. Thus, the hot water to be supplied is held at a fixed temperature. According to such construction, the bubbles in the hot water to be supplied can perfectly be removed while set temperature is raised, and hot water can be stably supplied.

Filed: 1986-03-10
Abstract: PURPOSE:To obtain a sensor which is small in the size of electrodes, and has high selectivity and long life by providing a fixed film formed by dispersing and fixing a nitron nitrate into a resin on the gate of an ion sensitive field effect type transistor (ISFET). CONSTITUTION:The nitrate ion sensor 2 consists of the ISFET fixed with the solid film contg. the nitron nitrate on the gate surface. A silver or silver chloride electrode or caromel electrode is usually used for the reference electrode 1. The measurement output is obtd. by bringing the reference electrode 1 and the ISFET2 for measurement into contact with the sample liquid 3 and measuring the difference between the output voltages. The charge density on the surface of the solid film changes to change the gate voltage of the ISFET2 according to the concn. of the nitrate ion if the nitron nitrate is brought into contact with the sample liquid contg. the nitrate ions and therefore, the quantitative measurement and detection of the concn. of the nitrate ion are made possible by measuring the output of the ISFET2 by the constant current of the drain or the constant bias voltage of the gate.

Abstract: PURPOSE:To decrease the area and the volume of a high-concentration diffused layer and to perform a high speed operation by determining the region of the high- concentration diffused layer which forms the source and the drain of a MOSFET based on the width of an oxidation resisting film which is formed on the side wall part of a gate electrode. CONSTITUTION:A gate electrode 4 is formed on a one-conductivity type semiconductor substrate 1 through a gate insulating film. Thereafter, an oxidation resisting film is formed on the entire surface of the substrate 1. When the oxidation resisting film undergoes anisotropic etching, a side wall 7 of the oxidation resisting film is formed on the side surface part of the gate electrode 4. Then, with the gate electrode 4 and the side wall 7 of the oxidation resisting film as a mask, the semiconductor substrate is oxidized, and an oxide film 8 is formed. Thereafter, the side wall of the oxidation resisting film is removed. With the gate electrode 4 and the oxide film 8 as a mask, reverse-conductivity type impurities are introduced into the semiconductor substrate 1. A source/drain diffused layer 10 is formed. A polycrystalline silicon layer 11 is formed on the entire surface of the substrate 1 including an opening part. The layer 11 is etched back, and the specified shape is formed. Thus the area of the high- concentration diffused area which is the source/drain region is formed in a small area.

Abstract: PURPOSE:To obtain a magnetic recording medium having a magnetic layer of a small coefft. of friction without decrease of S/N and clogging by incorporating a fatty acid into a back layer and transferring the fatty acid to the surface of the magnetic layer. CONSTITUTION:The magnetic recording medium is formed by adding a fatty acid ester to a magnetic coating liquid and adding the fatty acid to a coating liquid for the back layer, by which the deterioration of the magnetic coating liquid with age is prevented. The magnetic layer and the back layer contact each other and the fatty acid in the back layer transfers to the surface of the magnetic layer if the magnetic recording medium obtd. in such a manner is coiled and is preserved. The fatty acid and fatty acid ester exist eventually in the magnetic layer. The good running property of the magnetic recording medium is thus maintained and the increase of a drop-out and the decrease of S/N is prevented.

Title: Orientation regulating type diving instrument
Inventor: TOKUNAGA MITSUGO
IPC: B63G8/14
Filed: 1983-03-29
Abstract: PURPOSE:To enable smooth horizontal movement of a device as well as smooth vertical movement, by a method wherein detachable first and second ballasts are mounted. CONSTITUTION:Under condition in which both first ballast 2 and second ballast 3 are attached to a diving instrument body 1, the body 1 assumes, in water, an inverted orientation with a head down, and it is sunk with the weight of two pieces of the ballasts 2 and 3. When it is sunk to a given depth, operation of a controller causes separation of the ballast 2 from the body. This causes only the ballast 3 to be connected to the head of the body 1, and as a result, the body 1 assumes a horizontal orientation. When a work is completed, the ballast 3 is separated from the body 1. Under this condition, the head of the body 1 is decreased in weight, and thereby the body 1 floats up in an upright orientation with its head up.
