Title: Liquid level detector
Inventor: ICHIKAWA KOJI
IPC: G01F23/22
Filed: 1986-07-14
Abstract: PURPOSE:To accurately control the extent of insertion of a sucking body to a liquid and accurately detect the position of the liquid surface by oscillating the sample liquid in a sample vessel by an oscillation applying means. CONSTITUTION:The sucking body which is freely vertically moved by a vertical position control means is arranged above a sample vessel 52 where the sample liquid is stored, and the sample liquid can be sucked by a sucking means connected to the sucking body. The oscillation which is applied to the vessel 52 by an oscillation applying means 92 and is transmitted is detected as the voltage output of a piezoelectric element 101 provided in the sucking body or the sucking means. What the lower end of the sucking body is brought into contact with the liquid surface, the oscillation transmitted to the vessel 52 by the means 92 is transmitted to the sucking body through the sample liquid, and therefore, the element 101 receives this oscillation to generate a high output voltage. This voltage is detected to detect contacting between the sucking body and the sample liquid. Thus, between the sucking body and the sample liquid. Thus, contacting with the liquid surface is surely detected because oscillation transmission through bubbles and that through the liquid are greatly different from each other even if bubbles occur on the surface of the sample liquid.

Filed: 1997-06-06
Abstract: PROBLEM TO BE SOLVED: To provide an improved ultrasonic wave swirl flow meter including a housing having a slip on yoke interfit into a bluff body piping connector permanently attached in a fluid piping to be monitored so as to be removable. SOLUTION: An ultrasonic wave transmitter 40 and a receiver 42 are placed in the leg of a yoke so that an ultrasonic wave can run through swirl generated by fluid when the fluid runs around a bluff body 28. The possibility of the interruption of the fluid flow during the maintenance of an instrument and the mixing of an outside pollution with the fluid can be escaped by a slip on yoke. This flow meter uses a simple phase detector formed from an exclusive OR gate by combining it with an optimal phase range detecting means. Thus, the optimal phase range detecting means activates 90 deg. phase shift anytime a phase difference between a transmission wave and a reception ware is close to almost 0 deg. or 180 deg..

Title: Surface-designed metallic plate and production thereof
Inventor: KUBOTA AKIRA
IPC: C23F1/00
Filed: 1989-06-27
Abstract: PURPOSE:To produce a designed metallic plate having a surface pattern enriched in variety by forming the small mirror groups consisting of a flat recessed face on the metallic plate showing mirror face and then chemically etching a required part. CONSTITUTION:The surface of a metallic plate made of stainless steel is mirror- finished. Many small mirror groups consisting of a flat recessed face are formed by press working or a shot blasting method wherein small shperes such as glass bead are utilized as a medium. Then the required part of the surface is chemically etched by utilizing a ferric chloride soln., etc. This metallic plate has both surfaces of optical insensitivity of a satin face which has been formed by chemical etching treatment and optical sensitivity of many small mirror group parts. Therefore a dynamic design which is not heretofore obtained can be created. When the metallic plate is observed while moving it, singular effect is shown wherein the pattern shown by the small mirrors is extinguished or suddenly shown.

Title: Pillar structure of automobile
Inventor: SATO RYOSUKE
IPC: B62D25/04
Filed: 1999-06-11
Abstract: PROBLEM TO BE SOLVED: To efficiently absorb impact energy by piping a high pressure pipe and a low pressure pipe on the front side or the rear side of an inside space in close vicinity of each other, and positioning the high pressure pipe on the longitudinal directional outside of the low pressure pipe. SOLUTION: Since a low pressure pipe A has a large diameter and is positioned on the cabin inside R more than a high pressure pipe B, impact energy F acts on the low pressure pipe A in the first place, so that the low pressure pipe A collapses. The low pressure pipe A is pushed outside a car body to push the high pressure pipe B so as to abut to a vertical wall 11a of a recessed part 11. Since the low pressure pipe A is sandwiched between the vertical wall 11a of the recessed part 11 and the high pressure pipe B, the low pressure pipe A is prevented from longitudinal directional positional dislocation, and surely and sufficiently collapses in the position.  Since the depth W2 of the recessed part 11 almost coincides with a diameter W1 of the high pressure pipe B, contact points of the vertical wall 11a with the high pressure pipe B with respect to the low pressure pipe A become the almost same position in the car width direction, so that the low pressure pipe A can be sufficiently crushed.

Title: Inference system
Inventor: WADA SHINICHI
IPC: G06F9/44
Filed: 1989-06-27
Abstract: PURPOSE:To perform an inference in a short time by nalyzing and recording a selected hypothesis that was valid in an inference process and utilizing the hypothesis with preference for the subsequent executions. CONSTITUTION:At execution of an inference, an inter-hypothesis relation storage part 5 stores a used rule name, a selected hypothesis, a premise hypothesis, and a conclusion hypothesis in a set. A valid hypothesis analyzing part 7 extracts a chain of rules covering the given input and the selected hypothesis through the conclusion based on the relation between hypotheses recorded in the part 5. Thus the part 7 extracts a valid hypothesis and gives it to a hypothesis validity storage part 8. Then the inference is carried out via an input part 1 which inputs the value received from a user, a knowledge base 3 which stores an assembly of rules, and an inference processing part 2 which carries on the extraction of a hypothesis that used with preference the selected hypothesis validated by the part 8. As a result, an inference is carried out at a high speed by applying with preference the hypothesis decided more valid via the part 8.
