Title: Oxygen concentration detector
Inventor: NAKAE MAKOTO
IPC: G01N27/41
Filed: 1992-05-08
Abstract: PURPOSE:To precisely detect a stable oxygen concentration even if sudden fluctuation the pressure of a-measurement gas occurs by specifying the cross section and length of a diffusion hole and the size of chamber part volume. CONSTITUTION:The relation of the cross section S(mm<2>) and its length 1 (mm) of a diffusion hole 25 for limiting the inflow into a chamber part 100 of a measurement gas and the volume V(mm<2>) of the chamber part 100 is constituted so as to be 1<=S/(1.V)<=5. If the cross section S is enlarged, the length 1 is shortened and the volume V of the chamber part 100 is narrowed, the flow of a measurement gas allowed to flow in the chamber part 100 through the diffusion hole 25 is always constant even if the pressure of the measurement gas changes suddenly because a difference between the pressures of the inside and the outside of the chamber part 100 is difficult to produce. Accordingly sensor output can be held stably and precise measurement can be performed without any influence of the fluctuation in a sudden dynamic pressure of the measurement gas.

Title: Signal processing circuit
Inventor: YOSHIOKA TAKASHI
IPC: G01S15/96
Filed: 1999-04-23
Abstract: PROBLEM TO BE SOLVED: To suppress reduction in a S/N ratio of a display signal so as to display a high level signal by mutually comparing an echo stored in a memory with an echo detected in this time on a time base and extracting an echo having a level other than a maximum or minimum level. SOLUTION: A main processor 11 intensively controls an underwater detector. A controller 12 feeds a predetermined control signal to each circuit according to a command from the main processor 11. A transmission pulse oscillation circuit 13 generates a transmission pulse with a period T and modulates a ultrasonic wave signal into a transmission pulse via a transmission signal forming circuit 14 for forming a transmission signal. A signal processing circuit 19 displays an echo of the ultrasonic waves transmitted by a fixed period, stores echoes based on transmitted waves in several times in the past into a memory, and compares the echo stored in the memory with the echo detected in this time mutually on a time base for extracting an echo having a level other than a maximum/minimum level. Because an echo generated irregularly is not used, unnecessary waves can be removed.

Title: Manufacture of cage type rotor
Inventor: OGUSHI TETSURO
IPC: H02K17/16
Filed: 1989-05-09
Abstract: PURPOSE:To prevent the solidification of molten conductive material on the way of inflow into slots by a method wherein a coating material, gasified by the heat of the filled molten conductive material or chemical reaction between the molten conductive material, is applied on the inner surfaces of the slots before filling the molten conductive material. CONSTITUTION:A coating material, gasified at a temperature near the solidifying point of a conductive material 6 such as silicon oil and the like or lower than the same point, is applied on the inner surface of the slot 1b of a rotor core 9 to form a coating film 51. The coating film 51 is gasified instantaneously by coming into contact with the high temperature of the molten conductive material 6 upon the inflow of the same into the slot 1b. As a result, gas film 52 is formed between the conductive material 6 and the inner wall of the slot 1b whereby heat conduction from the conductive material 6 to the inner wall surface of the slot 1b is precluded. Accordingly, the temperature reduction of the conductive material 6 is delayed and the conductive material 6 flows without blockading the slot 1b, then, flows into an upper end ring unit 10b. According to this method, the solidification of the molten conductive material on the way of inflow into the slot may be prevented and a healthy electric conductor having no cavity may be obtained.

Title: Ink jet recorder
Inventor: KAWAMURA KIICHI
IPC: B41J2/175
Filed: 1980-08-25
Abstract: PURPOSE:To enhance resistance to vibration and impact by a method wherein a fluidic diode is placed in a head or in a part of an ink supply pipe in the vicinity of the head in such a direction as to inhibit the flow of an ink toward the head. CONSTITUTION:For example, the fluidic diode 9 analogous in is provided between a tube 7 and the head 1 and it is provided with tunnel-shaped passages 10, 11, 12, 13. A fluid is permitted to flow from the passage 11 to the passage 10 through the passage 13. On the other hand, when the fluid flows from the passage 10 to the passage 11, the fluid is divided into two portions which flow through the passages 12 and 13, respectively, and collide against each other, producing a large resistance to the flow of the fluid. The diode effect is applied to a high-velocity flow or a flow showing a rapid change. Accordingly, even if vibrations are applied to the tube 7 or a tank 8 is vibrated to cause the ink to vibrate, the rapid change in the flow of the ink generated on such occasion is absorbed by the fluidic diode 9 and the effect of the vibration on the head 1 can be alleviated greatly.
