Title: Normal/reverse rotatable fluid machinery
Inventor: IWAHASHI MASAAKI
IPC: F01D7/00
Filed: 1985-04-06
Abstract: PURPOSE:To simplify and make smaller the constitution of fluid machinery by rotatably installing a fitting boss for wings on the driving axis, limiting the range of the angle allowing the relative revolution of the driving axis and the fitting boss with a restrictive mechanism and changing over the orientation of wings through this relative revolution. CONSTITUTION:When a driving axis 1 is made to rotate in the X direction, the revolution of a fitting boss 4 is delayed compared with that of the driving axis 1 since the fitting boss 4, fixed to the driving axis by means of a fixing sleeve 2, tries to maintain its stationary position because of inertia. And in a state in which the convex part 11 of the engagement contacts one of the stoppers 10 at the concave part 9 of the fixed sleeve 2, and the relative revolution of the driving axis 1 and the fitting boss 4 is at a standstill, the fitting boss 4 revolves. As a result, a pinion gear 7 engaging with the bevel gear 8 of the driving axis 1 rotates and the wings 5 attached to the fitting boss 4 through an axis 6 also come to revolve. Accordingly, wings 5 take the optimum orientation for the X-direction rotation of the driving axis 1, which brings about the optimum operational property.

Title: Supporting structure of large-span roof
Inventor: MUKOYAMA YOICHI
IPC: E04B1/36
Filed: 1991-04-05
Abstract: PURPOSE:To obtain supporting structure capable to cope with temperature stress effectively and not against a seismic force, etc. CONSTITUTION:The beams positioned around the periphery of a roof 1 are supported at four center positions and four corners by means of supports 2a and 2b, respectively. The supports 2a and 2b support the roof by means of a roller for movement in the direction of the centroid and by means of a pin in the direction perpendicular to it. Since the movement in the direction of the centroid is supported by the roller, stress on the roof 1 due to temperature variation is relieved by the movement of a supporting point. Also, since the movement in the direction perpendicular to it is supported by means of the pin, the movement of the roof is made symmetrically to maintain a stable supporting structure.

IPC: F23N1/02
Filed: 1991-04-05
Abstract: PURPOSE:To watch a concentration of unburnt substance in ash all the time and efficiently control the operation of a coal combustion furnace by a method wherein the concentration of unburnt substance contained in discharging gas of combustion is calculated in its physical nature with a simple means based on a fuzzy deduction. CONSTITUTION:A fuzzy deduction part 1 takes each of data concerning a temperature TM within a combustion furnace, a load signal QS, a stain coefficient zetaB in the furnace, a double-stage combustion air rate TS, and a coal mixing rate MC and the like. It further estimates each of correction values of a furnace temperature T, a furnace air ratio lambda and a fine powder coal particle diameter Dp and a fuel ratio of coal substance. A reference part 2 prepares a distribution of furnace temperature T, a distribution of a furnace air ratio lambda, a distribution of a particle diameter Dp and a distribution of a reaction speed ratio beta with a coal quality as a reference distribution model. In addition, a correction part 3 corrects each of the reference values got from the reference part 2 in response to the corrected value corresponding to the fuzzy deduction part 1. A calculation part 4 may calculate a concentration C of non- ignited substances in the ash in response to each of the values corrected at the correcting part 3 and a reaction speed ratio outputted from the reference part 2.

Title: Refrigerant condenser
Inventor: YAMAMOTO KEN
IPC: F25B6/02
Filed: 1994-04-11
Abstract: PURPOSE:To provide a refrigerant condenser in which a condensing pressure in the condenser can be held at a predetermined value or more at the time of a low load by varying condensing capacity of the condenser to meet the load. CONSTITUTION:A first tube 17 is connected to an upper layer of an inlet side header 15 of a condenser 2 and has a U-shaped part 17a and a rising part 17b. A second tube is connected to a lower layer of the header 15. Since the speed of flow of refrigerant is high at the time of a high load, lubricant mixed with refrigerant can rise through the part 17, but when the load becomes low and the speed of flow of the refrigerant becomes low, the lubricant cannot rise through the part 17b and stays in the part 17a thereby to shut off the tube 17. Accordingly, the refrigerant flows into the condenser 2 only from the second tube.

Filed: 1978-06-16
Abstract: PURPOSE: To prevent the misdetection of the return signals at the transient time by absorbing the variation of the voltage with which the return signal is converted in case the return signal treated by the current mode of the multiple transmission device lacks for a fixed time.

The control signal given from control signal generation circuit 21 is applied to return signal monitor circuit 27 via the gate, and the output from reference voltage control circuit 28 is applied to return signal detection circuit 26. In case more than two units of the return signal lack, circuit 26 generates the abnormal signal to control circuit 28. Then the gain of the reference voltage generator is increased to well cope with the sudden increment of the return signal input, thus preventing the misdetection of the return signal at the transient time.
