Title: Thermal flowmeter
Inventor: UENO SADAYASU
IPC: F02D41/18
Filed: 1982-08-23
Abstract: PURPOSE:To improve the accuracy of measurement by providing a return line for making a current flow back from a temperature-sensitive element to a power source and a ground potential line of an amplifier conneced to the temperature-sensitive element, an by grounding said ground potential line within a signaling element. CONSTITUTION:A current is supplied from a battery 40 via a signaling line 50 to a sensor driving circuit 12 containing a temperature-sensitive element, a temperature compensation element and a control circuit, etc., and returns to the battery 40 via a return line 52. An air flow rate signal detected by the circuit 12 is sent to the positive input terminal of a differential amplifier from the return line 52 via a resistance line 15, and voltages at the opposite ends of a resistor detecting a heat current of the temperature-sensitive element from the return line 52 via resistance line 15 are given to the negative input terminal of said amplifier. In the differential amplifier 16, zero span adjustment is performed with a reference voltage from a constant-voltage circuit 18 via a feedback resistance 17. A difference output from the differential amplifier 16 is taken in CPU via a flow rate signal line 54 and an AD converter 32. A grounding line 56 is led from a sensor element 10 to a signal processing element 30 and grounded. The accuracy of measurement is improved, since the grounding line 56 and the return line 52 are separated from each other.

Title: Check valve
Inventor: TAMURA KOUZOU
IPC: F04D13/12
Filed: 1977-12-05
Abstract: PURPOSE: To make unnecessary the cutting work finishing of valve guide part by forming a relief part which is free from the contact with a circular valve at a prescribed position of the valve guide part and positioning the metal mold parting part at said relief part.  
     CONSTITUTION: The relief part 16 free from the contact with the inner peripheral surface of an annular valve 8 is formed by cutting in parallel the opposite side surfaces of the cylindrical body of the valve guide part 7 of a check valve body 2, and a metal mold parting part 9 is positioned at said relief part 16. Consequently, when the valve body 2 is formed from a pair of split molds having parting part 9 parallel to the axis center of the valve body 2 and a snap mold which forms a path 4 with the inner wall of a fluid passage 5 and slides in the axial direction of the valve body 2, the burr formed at parting part is positioned at the relief part 16 and does not contact the inner peripheral surface of the annular valve 8. Thus, without finishing the valve guide part 7 with cutting works, the abrasion of the annular valve 8 is prevented.

Title: Supporting structure for reactor pressure vessel
Inventor: KOBAYASHI KAZUHARU
IPC: G21C13/02
Filed: 1987-06-12
Abstract: PURPOSE:To save steel products by introducing high-temp. high-pressure steam into the water in a reduced pressure chamber by utilizing hollow columns to reduce the pressure in said chamber when a predicted accident arises. CONSTITUTION:The supporting structure for a reactor pressure vessel consists of the hollow columns 2 and pressure resistant plates 16 which segment the reduced pressure chamber 7 and an internal space 17. The high-temp. high- pressure steam filled in the upper space 5 of a partition floor 14 is released from column head apertures 4 at the top ends of the columns 2 through the columns 2 and vent holes 6 to the water 19 in the reduced pressure chamber 7 and is thereby volumetrically reduced when it is assumed that the piping of the vessel 3 is ruptured by the outbreak of the predicted accident. The generation of a high pressure over the entire part in the reduced pressure chamber 13 is, therefore, obviated and the steam is safely confined therein. The need for using thick steel plates is thereby eliminated and the saving of the steel plates is enabled.
