    摘要: A flow measurement device is disclosed, in which an accumulation of pollution substance onto a detection element is prevented, and which can measure a reverse flow similarly to a normal flow. On both ends of an outer wall 23 outer peripheral portion of a divided flow pipe 20 having a &OHgr;-shape pipe passage, there are oppositely formed an inlet port 25 and an outlet port 26, which open in faces orthogonal to a flow direction of a main flow M that is a detection object. Within the divided flow pipe 20, by a curved partition 27, plural branch flow passages 28a, 28b mutually branching and joining in the divided flow pipe 20 are formed. Inside both end portions of the outer wall 23, undulation portions 32, 33 are formed so as to clog an inlet and an outlet of the outer peripheral side branch flow passage 28a and, by this, throttles are formed respectively in a flow passage between the inlet port 25 and the inlet of the branch flow passage 28a and a flow passage between the outlet port 26 and the outlet of the branch flow passage 28a. In a bottom portion of the outer wall 23 of the divided flow pipe 20, a detection element 31 is attached so as to be exposed to a flow in the outer peripheral side branch flow passage 28a and, against its detection face, a down flow DW further divided from a divided flow D obliquely impinges.

    摘要: A flow rate and flow velocity measurement device. A part of a flow 10 in a main flow pipe 1, which is a detection object, is introduced into a passage of a divided flow pipe 2 and becomes a flow 11. The divided flow pipe 2 has a curved portion 2c or rather an inverted arc portion in which the flow is abruptly changed in direction or rather inverted by protuberances 2a, 2b formed preferably in symmetry in upstream and downstream sides of the curved portion 2c. Outside the main flow pipe 1, there is disposed on the bottom portion of the curved portion 2c of the divided flow pipe 2 a detection element 5 fixed to a support body 4 while protruding preferably 0.05-0.3 mm from flow passage faces 2e, 2f in the vicinity thereof. An opposed face 2d opposite to the detection element 5 protrudes toward the detection face so as to throttle the passage and to accelerate a flow speed at the element. Thus, in the curved portion 2c from the flow 11, a down flow 12 is constantly formed obliquely impinging against the detection face of the detection element 5, improving flow measurement accuracy within a wide flow speed range.

    摘要: A split-flow-type flowmeter in which an end portion of a flow splitter tube 1 is inserted into a main-flow pipe 10 having a diameter D. A flow splitter tube 1 includes a U-shaped split-flow passage 1a. A detection element is disposed at a bottom portion (not shown) of the U-shaped split-flow passage 1a. The split-flow passage 1a assumes a flow path structure symmetrical with respect to a plane passing through the detection element. A flow inlet 2a and a flow outlet 2b of the split-flow passage 1a face in mutually opposite directions along the flow direction of the main-flow pipe 10 and open symmetrically at the same position on the flow cross section of the main-flow pipe 10. In order to divert into the split-flow passage 1a a portion of relatively high flow rate of flow from the main-flow pipe 10, the center of opening of the flow inlet 2a/flow outlet 2b is positioned between the center of the flow cross section of the main-flow pipe 10 and an average-flow-velocity position at which flow in the main-flow pipe 10 is of an average flow velocity, as observed on the flow cross section of the main-flow pipe 10.

    摘要: A mass flow sensor includes a semiconductor substrate 1, an insulating thin film 2, heaters 311 and 312, temperature measurement resistors 321 and 322, and a protective layer 4. The heaters 311 and 312 are formed on the surface of the insulating thin film 2, and are provided adjacently such that the heater 311 is provided upstream the heater 312 and the heater 312 is provided downstream the heater 311. A cavity 5 is formed below the heaters 311 and 312, and the heaters are thermally insulated from the remaining portion of the semiconductor substrate. The temperature measurement resistors 321 and 322 are formed on the top surface of the insulating thin film 2, and are provided at opposite sides of the heaters 311 and 312, such that the resistors are aligned with respect to the flow passage of a fluid. In the mass flow sensor and the mass flowmeter including the sensor, the flow rate and flow direction of a fluid can be detected by means of merely the heaters 311 and 312, which are active elements. Therefore, the sensor and the flowmeter exhibits high-speed response with respect to change in the flow rate of the fluid.

    摘要: In the vehicle-lamp lighting-on device, a body case has a connection opening formed in the front end thereof. A lighting-on transformer is disposed within the body case. The transformer includes a core housing with an iron core and a coil bobbin with a secondary coil wound thereon. The connection opening of the body case is shielded at the front end of the lighting-on transformer. A socket for receiving a vehicle discharge lamp includes a high-voltage terminal and low-voltage terminals. When the socket is inserted into the connection opening of the body case, the high-voltage terminal of the socket is connected to the high-voltage side terminal of the lighting-on transformer, and the low-voltage terminals are connected to the low-voltage side terminals. The connection opening of the body case is shielded by the front surface (made of insulating material) of the lighting-on transformer. The vehicle-lamp lighting-on device can be completed by merely attaching the socket to the assembly of the lighting-on transformer and the body case. Therefore, the assembly of the device is easy. Further, the height of the vehicle-lamp lighting-on device is reduced overall since there is no need to form a wall corresponding to the shielding member in the body case.

    摘要: In a high-voltage transformer, an insulating ring is placed on and along the inner surface of the core housing, and gaps are formed between the tips of the flange-like plates of the coil bobbin and the inner side of the insulating ring. With such a construction, the gaps and the insulating ring are provided between the coil bobbin and the inner wall of the core housing, so that the flange-like plates of the coil bobbin do not come in contact with the inner surface of cylindrical wall of the core housing. Therefore, a surface distance of the coil bobbin ranges to a contact surface of the coil bobbin where it comes in contact with the front wall of the core housing. The surface distance is elongated. The voltage drop by the creepage discharge does no occur.
