Title: Built-in stereo microphone
Inventor: HAMADA ICHIRO
IPC: H04R1/40
Filed: 1992-04-30
Abstract: PURPOSE:To miniaturize a video camera and to reduce weight by electrically processing sound absorbed by a plural microphone capsules and cancelling the vibration sound of an internal mechanism. CONSTITUTION:A microphone unit 7 consists of a substrate 8, two microphone capsules 9/9 for right and left channels (L/R), and a microphone capsule 10 fixed at the center of the unit. Since the output signals received by the microphone capsules 9, 9 and converted into voice signals contain internal vibration sound as well as the external sound of a main body cabinet 2 of a video camera 1, the output signal consisting of the only internal vibration sound of the main body cabinet 2 in the video camera received by the microphone capsule 10 and converted into voice signals are inputted into the 1st adder and L and R channels together with the output signals of the microphone capsules 9, 9 are also inputted to the 1st adder. Then the output signal of the microphone capsule 10 is subtracted from the output signal by the 1st adder.

Title: Ball tap for water tank
Inventor: MINAMIYAMA TAKAYA
IPC: E03D1/32
Filed: 1997-05-26
Abstract: PROBLEM TO BE SOLVED: To change a water stop to a water discharge surely and stably by providing a wall part for making the flow of a sub-flow passage which is a flow of the periphery direction of a main flow water passage to a nearly one direction near the upper end of the main water passage of a main flow water passage. SOLUTION: A wall part 15 is provided near the upper end of the main water passage 14 of a main flow water passage 11. This wall parts 15 achieves the part for making the flow of a bub-flow passage 11B to a nearly one direction for the water flow in the main flow water passage 11 formed by the main flow passage 11A and the sub-flow passage 11B which is a flow to the periphery direction. In other words, the wall part 15 makes the flow of the sub-flow passage 11B to one direction substantially, even if a few disturbance factor is existed. Thereby, as the change of the pressure distribution in the main flow water passage 11 is restrined to minimum, a water pressure can be detected favorally by utilizing a diaphragm hole 22. Therefore, the switch from a water stop to a water discharge can be performed surely and stably.

Abstract: PROBLEM TO BE SOLVED: To effectively prevent the breakage of blades or the like and obtain the long life of the blades by providing buffer members for absorbing impact force due to the collision of sludge lump between the blades and a main shaft. SOLUTION: A main shaft 2 is provided with buffer members 21 made of an elastic material. The buffer member 21 is formed by connecting one end of a cylinder member made of a rubber to the surface of a metallc base. An attaching screw fixed to the back surface of the metallic base is detachably and threadedly attached to a tapped hole provided on the main shaft 2. The other end of the buffer member 21 formed in a gently spherical shape is opposed to the blade 6. The attaching position of the buffer member 21 is set to a position abutting on a position nearer to the end part of the blade 6 than to the center of gravity position of the blade 6. Since the buffer member 21 is soft, the waveform of impact force has a frequency component lower than the natural frequency of the bending of the blade 6. A stress waveform after collision rarely shows a vibration.
