Title: Variable resistor and bath with hot water supplying apparatus using the same
Inventor: KODAMA MASARU
IPC: F24H1/46
Filed: 1994-03-31
Abstract: PURPOSE:To control arbitrary flow by providing means for imparting energizing force against closing movement of a valve disc at the disc. CONSTITUTION:When other hot water supply cock for a shower, a lavatory, etc., is opened during hot water supplying to a bathtub, a variable resistor 30 temporarily reduces a pressure of a valve chamber 33 from a pressure chamber 31 according to a resistance difference between a general-purpose hot water supply passage 13 and a bath hot water supply passage 12, and hence a pressure of a secondary pressure chamber 32 drops from that of the chamber 31. Accordingly, a central movable part of a diaphragm 34 rises against a tension of a coiled spring 36, and stops at a position balanced with the tension. Simultaneously, a disc 42 also rises, an interval between the disc 42 and an opening 40 is reduced as indicated by two-dotted chain lines, and an opening area between the chambers 31 and 33 is narrowed. Thus, a flow rate to the chamber 33 is limited to reduce a flow rate to the passage 12. On the contrary, a reduction in the flow rate to the passage 13 is suppressed, and hot water can be comfortably used for the shower, etc.

Title: Combustor for super sonic air flow
Inventor: SEGAWA KIYOSHI
IPC: F23R3/16
Filed: 1993-03-23
Abstract: PURPOSE:To carry out ignition easily and maintain flame stably. CONSTITUTION:A circulating flow inducer 3 having a sharp top part on the front rim part of a fuel strut 2 is arranged, so that inclined shock wave is generated on the top end thereof, an circulating flow is formed in a range enclosed with three of inclined shock wave, the circulating flow inducer 3, and the front rim part of the fuel strut 2. When fuel 6 is injected into a high temperature circulating flow 8 whose temperature is raised and pressure is boosted after shock wave is passed, self-ignition can be carried out. Since circulating flow is exerted constantly, stable flame can be maintained. Since a shock wave is not stuck on the fuel strut 2 directly, wave making resistance and energy loss can be reduced so as to improve a starting performance as an engine.

Title: Automatic film winder
Inventor: YAMADA MINORU
IPC: G03B1/00
Filed: 1979-05-24
Abstract: PURPOSE: To prevent film from being wound in telescopic form and linear form by making the outside diameter of one end part of a film winding member larger than the outside diameter of the other portion.  
     CONSTITUTION: The film housed in a patrone chamber is unrolled by every fixed length by a sprocket and the leading end small-width part A of the film is wound to a winding member 9 by way of the rubber roller 29 of the 2nd pressure member 11 and the roller 24 of the 1st pressure member 10. Here, the member 9 consists of an inside barrel having a flange 12a and an outside barrel 13 of high friction elastic material making close contact therewith. The outside diameter of the end part 13a closer to the flange 12a is made slightly larger than the outside diameter of the other part 13b. Because of this large-diameter part 13a, the friction force of the film differs and the downward thrust force acts upon the leading end small-width part A, thus the winding is started in the state that it is held pressed to the flange 12a. Thereby, the film is advanced in the linear track and is prevented from being wound in telescopic form or linear form.

Abstract: PURPOSE:To set an objective split ratio by simple operation by making the inlet pressure of a column constant and setting the flow rate of a split outlet to 0 to calculate the flow rate of the split outlet at the time of a set split ratio according to a predetermined formula. CONSTITUTION:A pressure regulator FC1 is controlled by an electric control part 12 to make the secondary pressure P0 of carrier gas constant. When the flow rate U2 of a split outlet 8 is set to 0 by controlling a flow rate controller FC2, since the flow rate U1 of a column 6 becomes equal to the flow rate U0 detected by the regulator FC1, the flow rate U10 of the carrier gas at the time of pressure P0 is cleared. The flow rate of the split outlet ready to set from an objective split ratio S and the flow rate U1 according to formula U2=U10(1-S)/S is calculated by the control part 12. By this method, the split ratio of a gas chromatograph equipped with a column is easily set.
