Title: Thermal type flowmeter
Inventor: TANIMOTO KOJI
IPC: G01F1/68
Filed: 1986-04-08
Abstract: PURPOSE:To detect an accurate flow rate even when ambient temperature varies by arranging all resistances which constitute a bridge circuit in a fluid flow passage. CONSTITUTION:A heating resistance RH for flow rate detection which is made of a platinum wire and a resistance RK for temperature compensation for fluid temperature detection which has a platinum thin film on the surface of an insulator and is equipped with a trimming groove a coating film constitute a bridge circuit B together with resistances R1-R3 and are arranged in the fluid passage 1. In this case, the resistance RH is so set as to balance the circuit B when the temperature is specific temperature higher than the temperature of fluid and if the flow rate varies, the circuit B becomes unbalanced to cause the output of a differential amplifier circuit 3 to vary the base potential of a power transistor (TR) 4, and a current supplied from the TR 4 to the circuit B varies so that the resistance RH has a specific value. Therefore, when the fluid temperature does not vary, respective resistance values of the circuit do not vary and the relation between an output voltage which is the voltage across the resistance R3 and the flow rate becomes constant. The resistances R2 and R1 also vary with the fluid temperature, but temperature compensation including resistance variations of the R2 and R1 is performed previously to improve measurement accuracy.

Title: Removing method for phosphates in liquid
Inventor: TANAKA TOSHIHIRO
IPC: C02F5/02
Filed: 1979-06-30
Abstract: PURPOSE: To remove phosphates in a liq. stably and efficiently over a long time by allowing the liq. containing phosphates to contact to a composite consisting of cement, an alkali agent and a calcium carbonate-contg. mineral followed by contact dephosphorization.  
     CONSTITUTION: In a method of dephosphorizing a liq. such as sewage or industiral waste water by allowing dissolvable phosphates contained in the liq. to contact to a calcium phosphate-base phosphate mineral, the liq. is allowed to previously contact to a composite consisting of cement, an alkali agent and a calcium carbonate-contg. mineral. Thus, alkalinity constituents in the liq. are converted into calcium carbonate, which crystallizes and sticks to the composite, and then the liq. is softened in a decarboxylation process. Since alkalinity constituents are removed beforehand, phosphates can be removed efficiently and stably over a long term.

Abstract: PURPOSE:To make the oxygen gas absorbable ever so sufficient at the outer side surface of a cathode plate, by disposing a filling plate between the cathode plate located at the end face of a pole group and a battery jar rib, prior to the injection of an electrolyte, while removing the filling plate after the injection. CONSTITUTION:A cathode plate 3a situated at the end face of a pole group 1 consisting of an anode plate 2, a cathode plate 3 and a separator 4 is made to come into contact with a rib 7 installed in a battery jar 6, then a filling plate 8 is disposed in the clearance between 3a and 7, and inserted into th battery jar 6.

Abstract: PURPOSE:To enable the inspection of a noncircular gear, by a method wherein an engaging movement of a gear and a rack tooth-shaped measuring point is compared with a rolling movement, of a template mounted coaxially with the gear, and of a rule, which is conducted without slippage by means of magnets. CONSTITUTION:An engagement movement of a noncircular gear and a measuring point equivalent to a rack tooth shape is compared with a movement in which a pitch curve or basic curve-shaped template, being mounted coaxially with the gear, is caused to roll without slippage by means of a magnet. For example, a noncircular gear 1 and a template 2, having a profile being equal to a pitch circle, are mounted coaxially with a shaft 20. Through the working of a slide 6 and a weight 16, the former engages a rack tooth-shaped measuring point 4, and the latter is caused to roll along a straight rule 3 without slippage through the function of magnets 21 and 19. In case there is an error in the gear shape, a relative movement between slides 10 and 11 is created, and thereby the use of an indicator or the like permits the detection thereof.
