Title: Manufacture of diluted gas
Inventor: OKA SHIYOUTAROU
IPC: G01N1/22
Filed: 1983-12-29
Abstract: PURPOSE:To make it possible to set a diluting rate, whose dynamic range is wide of selected value, by keeping the pressures of a raw gas and a diluting gas at constant levels, mixing both gases alternately at a specified switching period many times through selector valves, and obtaining a diluted gas having a desired concentration. CONSTITUTION:The pressures of a raw gas 2 and a diluting gas are kept at constant levels by back pressure regulating valves 3 and 3'. A three-way solenoid valve 5 alternately supplies the gas 2 and the gas 1 to a diluted gas path at a preset period. A solenoid valve 17 is opened only when the gas 1 flows and exhausts the gas 2, whose flow rate is controlled by a needle valve 18. Back pressure regulating valves 6 and 6' regulate the pressures of the mixed gas and the gas 1 to the specified values, respectively. The mixed gas is more uniformly mixed in a buffer tank 9. The diluted gas is alternately mixed with the gas 1 at another specified period by a three-way solenoid valve 10 and supplied to a buffer tank 14.

Abstract: PURPOSE:To obtain an exhibition board for a number of jewels which improves the image of a shop by forming the upper part side of an exhibition plane nearly vertical, and forming the lower part side of the exhibition plane in curved form forward on the upper part side of the exhibition plane. CONSTITUTION:Since an exhibition plane 14 is formed vertical on the upper part 43 in comparison with the near center part and formed in curved form on the lower part 44 in comparison with the center part, a number of rings 5 can be exhibited, even if the exhibition plane 14 is formed wide, at a narrow place, because the inner depth is narrow. Since the inner depth of the exhibition plane 14 is narrow and the lower part is curved upwardly, all the rings on the exhibition plane 14 can be seen easily without directing the face downward. Further, the rings 5 are held so as to be erected on the exhibition plane 14 and in three-dimensional form, and the reflection parts utilizing illumination is made wide, the exhibition effect is improved, and protection by window glass on the front surface is eliminated, thus the opened effect can be achieved.

Title: Flow rate sensor
Inventor: TAKESHITA SHIRO
IPC: G01F1/32
Filed: 1985-11-08
Abstract: PURPOSE:To make it possible to select detection sensitivity, by using a photosensor in a signal detection means and utilizing the change in the transmission quantity of light due to the vibration of a movable plate as a signal source. CONSTITUTION:A flow rate sensor is integrally constituted of a vortex generating column 1 and a detector 2 and a flow passage 3 through which fluid flows from the direction shown by an arrow is provided. When the fluid flows through the flow passage 3, a cyclic Karman vortex 9 is generated behind the detector 2 in the downstream side of the vortex generating column 1 and the movable plate 6 faced to the outer flow passage 3 of the detector 2 vibrates around a support 7 being a fulcrum at vortex frequency proportional to a flow speed. Because the vortex generating column 1 and the detector 2 are integrated as mentioned above, the space for the flow rate sensor is small and said sensor can be arranged in an arbitrary flow passage. Because said detection method employs the counting of the intensity of the light from a photosensor 4 changing in accordance with the movement of a through-hole 5 as an input signal, sensitivity can be selected by properly selecting the length, thickness and material quality of the movable plate 6 and the diameter of the through-hole 5.
