Title: Ceramic moisture sensor
Inventor: YOSHIKADO SHINZO
IPC: G01N27/12
Filed: 1987-03-12
Abstract: PURPOSE:To heighten the rate of adsorption and desorption of moisture components and the conductivity of protons, by forming a thin film layer of hygroscopic amorphous ceramics on the surface of a conductive layer by sputtering while a moisture permeating conductive thin film layer is formed outside the ceramic layer. CONSTITUTION:An aluminum vacuum deposited film 2 is formed on a glass substrate 1 beforehand. Prederrite is mixed with a potassium oxide or potassium hydroxide at a proper weight ratio and melted by heat up to 800 deg.C-1,400 deg.C to react with potassium oxide. After cooled spontaneously, the product is melted into pure water, a sediment thus obtained is molded under pressure to be used as a target for sputtering. By sputtering, an amorphous ceramic layer 3 is formed as film on a deposited film thus obtained, and moreover, gold is vacuum evaporated thereon to obtain a sensor by forming an electrode 4. A logarithmic resistance value in resistance-absolute moisture characteristic of the sensor changes linearly in a wide range, as much as 1,000 times. Within the range, the sensor is easy to handle practically with a higher sensitivity.

Title: Wheel supporting structure of four-wheel working vehicle
Inventor: TANAKA MASAICHI
IPC: B60G17/005
Filed: 1985-03-20
Abstract: PURPOSE:To improve safety of a four-wheel working vehicle for farming use, etc. by constituting its wheel supporting structure in such a way that two oil chambers of a supporting mechanism for vertically movable wheels are communicated with each other when pressure in one of the oil chambers is above a specified value and are cut off when the oil pressure declines below the specified value. CONSTITUTION:Vertically movable wheels 1 are supported with 4-serial linking- type suspension linkage mechanisms 16a, 16b, which are in turn supported with oil pressure cylinders 17a, 17b. And oil chambers a, a of the two oil pressure cylinders 17a, 17b are connected with oil passages 19a, 19b equipped with relief valves 20a, 20b, which are opened with the oil pressure of a specified value, in reverse directions. Due to such constitution, if pressure in one of the oil chambers (a), (a) surpasses the specified value, the corresponding relief valve 20a or 20b is opened, resulting in the transfer of pressure oil. And if the pressure declines below the specified value, the opened relief valve comes to be closed. Accordingly, the vehicle can run safely even on unprepared or slanting grounds.

This is bisected along the cutting line (e) to obtain circular truncated-cone-form members 10a, 10b. A circular stock 10c is press-formed in the arrow direction. The portions extended outward become thinner as they go furhter from the axial center and the portions formed at the axial center become thicker as they go closer to the axial center, whereby a truncated-cone-form part 10d is obtained. These truncated-cone- form members and hub mounting flat flate are coupled to constitute the disc.

Abstract: PROBLEM TO BE SOLVED: To monitor a person who is taking a bath so as not to fall down and sink in a bathtub during bathing by detecting light from a light emitter to be received by a light receiver, monitoring whether the person keeps his/her consciousness during bathing on the basis of a detected light signal and outputting a warning signal when the person is judged to have last his/her consciousness. SOLUTION: When the person enters a bathtub 103, part of his/her body is located higher than the level of the water filled in the bathtub 103 when the normal position of the person is held in the bathtub. An optical path of a beam 11 emitted from the light emitter 1 is formed at a position of the height of the person's body. When the person in the bathtub 103 loses his/her consciousness for some reasons and sinks in the bathtub 103, an object to shield the light 11 from the light emitter 1 disappears, and the intensity of the light to be received by the light receiver 2 becomes larger.  The signal obtained from the light receiver 2 is monitored for a specified period, and when the light intensity does not become equal to or less than a specified value, it is judged that the person has sunk in the bathtub 103 and an alarm raising signal and a control signal are transmitted to an alarm raising means 4 and a hot water draining means 5.
