Title: Humidity measuring apparatus
Inventor: YAMADA KATSU
IPC: G01N27/12
Filed: 1988-06-29
Abstract: PURPOSE:To correct the temperature characteristics of the output of a humidity sensor with relatively few data indicating temperature characteristics by writing relative humidity data at various humidities of the humidity sensor and at various temperatures in a ROM in a matrix pattern beforehand. CONSTITUTION:A ROM 6 has an address corresponding to the intersection of an abscissa where temperature T of a temperature sensor2 is set at a 20 deg.C interval and an ordinate where output voltage H of a humidity sensor 1 is set at a 100mV interval. Relative humidity is written at each address. Namely, the relative humidifies at a plurality of typical points, e.g. points A-D, on the temperature characteristic curves shown in Figure (b) are written in the ROM 6 (Figure b) beforehand. A microcomputer 5 has an address specifying function for reading in the ROM 6. When the detected temperature T and the voltage H agree with the axes, the data of the address of the intersection are read, and the measured value is obtained. When the agreed address is not present, four points comprising the points A-D shown in Figure (b) are sequentially connected with straight lines. The relative humidity F at an actually measured point P included in the region surrounded by the lines is obtained by and determined by the approximation with a straight line.

Abstract: PROBLEM TO BE SOLVED: To prevent tumbling of load and to reduce the time and to save labor required for loading with a mounting table built up in a rotative simple structure by a method wherein load supporting frames each having an upper fitting hole and a lower projecting piece are attached so as to fall toward the inside only to revolving shafts at both ends of a base having fork bases at its underside. SOLUTION: Fork bases 2 are provided at the underside of a base 1. Load supporting frames 3 are attached respectively to revolving shafts 4 so as to fall toward the inside only, turning round each of the revolving shafts 4, and when the frames are raised, the frames are supported with projecting pieces 5 thereof fitted respectively to the fork base 2. A connecting bar 7 is inserted respectively into fitting holes 6 and the load supporting frames 3 are fixed therewith. When used, for instance in the case of conveying lumbers, the load supporting frames 3 are raised and the lumbers are mounted with the connecting bar 7 inserred into each of the fitting holes 6. Since piling-up becomes possible with the load supporting frames 3 folded down toward the inside, housing or storing does not require much space.  In the case of using a crane, loading and unloading can be made in desired directions with hanging made with a crane rope at the upper parts of the load supporting frames 3.

Title: Controller of compressor
Inventor: TAKETA KAZUHIRO
IPC: F04D27/02
Filed: 1990-06-20
Abstract: PURPOSE:To avoid abnormal operation of a compressor and a drive machine by selecting the maximum value of a control signal and an output signal of a flow regulator taking an input signal of a detection value of an entrance flow of a compressor, and regulating a recycle flow of gas provided for preventing the compressor from surging. CONSTITUTION:When a suction pressure is increased largely (point A), a discharge pressure is increased, and an exit flow is also increased, so a rotation number decreasing signal is given (point B) for an output of a regulator. The rotation number of a drive 11 is decreased by this for adjustment, but if it need be less than a limit rotation number (minimum rotation number), the rotation number is set at the minimum rotation number Nmin (point C), and a flow regulating valve 18 is regulated to increase a recycle flow (Q1 Q2) for adjustment (point D). A compressor 12 can thus be operated without exceeding the limit rotation number.

Filed: 1989-06-23
Abstract: PURPOSE:To secure required amount of air-fuel mixture for cooling by a method wherein a second air scavenging passage for communicating between an inlet port and a discharge port respectively formed on a cylinder is formed on a cylinder body while a vent hole is formed on a piston skirt. CONSTITUTION:In a two-cycle engine 1, air-fuel mixture primarily compressed in a crank chamber 2c is fed from an air scavenging port 18b via a first air scavenging passage into a cylinder 18. At this time a second air scavenging passage 3b for communicating between an inlet port 18d and a discharge port 18c formed on the lower and upper sections of the cylinder 18 respectively is formed on a cylinder body 3. A vent hole 17c for communicating with the inlet port 18d at the time of air scavenging is formed on a skirt 17b of a piston 17. Thus a part of air-fuel mixture is forced to pass through inside the piston 17 and then pushed in an upper part of the piston 17 of the cylinder 18. Therefore required flow rate of air-fuel mixture for cooling can be secured while the piston 17 is securely cooled from inside to improve cooling property.
