Title: Detecting apparatus of physical moving amount of relatively moving body
Inventor: HIRANO MASAO
IPC: G01P3/481
Filed: 1991-06-28
Abstract: PURPOSE:To obtain a detecting apparatus to detect the physical moving amournt of relatively moving bodies which can sufficiently enhance the reliability and the measuring accuracy. CONSTITUTION:Magnetic field generating means 6a, 6b are mounted to a rotor 5. A stator 3 is provided with optical fiber fluxes 4a, 4b, 4c, 4d which rotate the plane of polarization of the penetrating light because of the Faraday effect, by the magnetic field formed by the magnetic field generating means. As the physical amount depending on the rotating angle of the plane of polarization of the light passing through the optical fibers is observed, the physical relative moving amount of both objects can be obtained. Accordingly, it is sufficient only to transmit the light for measurement in the optical fibers, and not necessary to transmit the light through an optical member disposed in the predetermined spatial positional relations}rip to a moving part or a fixing part. As a result of this, factors causing the measuring errors, for example, the change of the positional relationship of the optical member or the change of the condition of the transmission line, etc., are eliminated, and the reliability and the measuring accuracy can be remarkably improved.

Title: Microwave integrated circuit
Inventor: IIDA AKIO
IPC: H01P1/16
Filed: 1982-09-13
Abstract: PURPOSE:To obtain a microwave integrated circuit which excels in the reproducibility with a low cost and also can apply the bias voltage to a semiconductor element, by setting vertically two metallic strips which are connected at the center part with a small resistance and has a total length of about half wavelength including a resistor to the rear side of a substrate having two slits parallel to each other and therefore suppressing transmission of an odd mode. CONSTITUTION:The length of a metallic strip 7 is set at about 1/4 wavelength with a frequency with which the suppression of an odd mode is desired, and the total length of the strip including a resistor 8 is set at about half wavelength. An even mode TEM is applied from the left side and not connected to the strip 7 to be transmitted to the right side if the width is reduced for the strip 7 which is vertical to the mode traveling direction. However an odd mode applied from the left side has a magnetic field component in its traveling direction. Therefore the radio wave is connected to the strip 7, and the electric power is consumed by the resistor 8. Thus the odd mode does not substantially propagate to the right side. The connection between the odd mode and the strip 7 is maximum if the total length of the strip 7 including the resistor 8 is set at about half wave. The parallel slits 6a and 6b are shown in the figure.

Filed: 1999-06-07
Abstract: PROBLEM TO BE SOLVED: To secure both high ventilation properties and anti-liquid spill properties with its structure simplified. SOLUTION: A kerf 32 is formed up in a packing 3 assembled with the inner side of a cap 2 having a vent hole 23. Paired pedestal parts 24 are formed at both the sides of a groove 25 communicating the kerf 32 with the vent hole 23 in the inner surface of the cap 2. When the inside of a washer tank 1 is negative in pressure, the packing 3 is inwardly deformed, and since there is a gap in the kerf 32, the inside of the washer tank 1 can be kept at atmospheric pressure. When the packing 3 is subjected to positive pressure by means of washing in the washer tank 1, since the packing 3 will never be deformed even if it is hit against the pedestal 24, there will never be any gap in the kerf 32, and washing is hardly spilled out.
