Title: Hot wire type current meter
Inventor: OOYAMA NOBUSHIGE
IPC: G01P5/12
Filed: 1981-04-20
Abstract: PURPOSE: To reduce error in measurement in a hot wire type current meter by installing a shielding member at the supporting member of an electric resistance heat generating body in order to obstruct heat conduction due to change around the shielding member in the speed of a flowing liquid.  
     CONSTITUTION: An electric resistor 1 such as platinum is installed on the surface 2 of an insulating supporter 2 and insulating coating 4 is applied. The supporter 2 is fixed with a supporting member 3. A hot wire type current meter is constituted with a measuring bridge that contains the resistor 1 in its one side. With balancing in the bridge the temperature of the resistor 1 reaches specified temperature. Because each end of the supporting body 2 and a part of the supporting member 3 are covered with a covering body 5 and a guide plate 17, the fluid at the section that is covered is stopped when flow rate is raised, only the fluid at the resistor 1 changes its flow rate. Accordingly change in the power consumption is entirely made to correspond to the change in flow rate, making it possible to measure exactly the flow rate. The temperature of the covered body and the ambient temperature can be made the same by means of a ventilat ing hole 16.

Abstract: PURPOSE:To provide surely a predetermined angle advancing property by means a mechanical control by providing a fuel injection pump having a sleeve control means or the like and a mechanical governor having a second variable means or the like for shifting the position of the control means or a first variable means according to an engine load. CONSTITUTION:When the adjusting screw 71 of the load angle advance adjusting mechanism 71 of a second variable means is operated, an adjusting lever 72 is rotated about a pivot 74. Thus, the cam 65 of the link mechanism 61 of a first variable means is rotated about an eccentric shaft 65c so that a position in which a cam face 65a abuts against a stopper 42 is shifted. However, even if the initial position of the cam 65 is shifted, a pin 65b engages with an engaging groove of a control lever 64. As a result, a shifter 52, a floating lever 62, respective control levers 63, 64 and cam 65 are shifted according to a centrifugal force of a fly weight 51, i.e. the rotational speed change of a fuel injection pump 2, so that positions of a timing control rack 4 and a control sleeve 24 are varied.

Abstract: PURPOSE:To improve the directivity and wavelength selectivity of light and to manufacture a microcavity laser from the above needlelike crystals. CONSTITUTION:Needlelike crystals 2, whose wavelengths are made equal and which respectively have a P-N junction, are arranged on a semiconductor substrate 3 in such a way that the intervals between the crystals 2 is integral multiples of the wavelength, whereby coherent light, whose wavelength and phase are even, is emitted in the left and right directions of the diagram. When this arrangement is expanded two-dimensionally, the coherent light can be emitted in various directions.

By arranging conductive rods at interals of an integral multiples of an oscillation wavelength, a semiconductor laser can be realized and an optical antenna can be manufactured. Moreover, as a microcavity laser, which is extremely small in threshold current, a coherent light-emitting element having not a threshold value and an LED can be manufactured, an optical element is very effective in the field of optical communication.
