To provide a well balanced squirrel-cage rotor for an electric motor, quantities of braze used to bond various rotor components are different from each other so as to serve as balance weight in order to improve balance.

Squirrel-cage rotor for an electric motor and its production method

[Theme] To provide a device or a judging method for judging the type of liquid inside a container that can be applied to containers of various shapes and can be applied to cases where the remaining amounts of liquids in containers differ. [Solution Means] This invention's device for judging the type of liquid inside a container is equipped with: a plate capacitor, wherein two plate electrodesandare positioned in opposing manner; a container supporting member, holding, in a region besides the region sandwiched between plate electrodesand, a non-conductive containerthat can contain a liquid in its interior; an oscillation circuit, containing capacitor; and a control part, detecting the oscillation frequency of the oscillation circuit; and container supporting memberis arranged to adjust the distance from plate electrodeto containerin accordance with the size of container. Also, a third electrode, of the same electric potential as plate electrode, is disposed in contact with a bottom part of container

Device for judging types of liquid in container and control method therefor

A technique for quickly determining the type of liquid in a container externally regardless of the material of the container, preferably contactlessly. A halogen heaterand an infrared thermopileare disposed outside an electrically conductive containermade of aluminum, for example. The surface temperature of the containeris measured when the halogen heateris off, followed by the turning-on of the halogen heaterfor two seconds, for example. The surface temperature of the containeris then measured, and a difference from the previous result of measurement is calculated. If the difference is smaller than a threshold value, the liquid in the container is determined to be a safe liquid consisting primarily of water, and a blue lamp is activated. If the difference is greater than the threshold value, the liquid in the container cannot be determined to be a safe liquid consisting primarily of water, and a red lamp is activated, indicating abnormality.

Apparatus for determining type of liquid in a container and method for controlling the apparatus

A fluid pressure sensor () for measuring the pressure of a fluid comprises a diaphragm portion () which is a strain generating body, a silicon oxide film () as an insulating film, and a strain gauge () made of crystalline silicon, and austenitic precipitation hardening type Fe&#x2014;Ni heat-resisting steel excellent in mechanical strength and corrosion resistance is used for the diaphragm portion (). The silicon oxide film () is formed with the internal stress thereof adjusted to the range from &#x2212;150 to 130 MPa. With this feature, the fluid pressure sensor () ensures high precision and reliability, and may be used even for measurement of a highly corrosive fluid.

A memory apparatus for vehicle information is provided in which the image data of the vehicle's condition in a traffic accident, a traffic offense, a drive condition from the occurrence of an accident to the vehicle's stop after the accident, and a sensor data are memorized and held in a flash memory repeatedly. The memory apparatus enables an analysis of an accident with high precision upon the reproduction of the data of the vehicle's condition, and can be used to provide evidence relating to a traffic offense. The image signals from a CCD camera,, a RAM,for memorizing the sensor's information from a vehicle speed sensor,, a steering angle sensor,, a brake pressure sensor,, and an acceleration sensor,, and a flash memory,for permanently memorizing the signals of the RAM,, are controlled through a CPU,. The record information of the RAM,is transferred to the flash memory,based on the operation of a collision sensor,to memorize and hold the information. Moreover, the signal of the flash memory,is converted into a video signal to output the information during a reproduction.

A controlling apparatus controls a suction performance of a blower motor which is installed into a cleaner main body. The controlling apparatus increases the suction performance when a suction nozzle is operated and decreases the suction performance when the suction nozzle is stopped. Corresponding to a floor use suction nozzle and a crevice use suction nozzle, at a predetermined air flow amount range, the most suitable operation control being suited to a discriminated suction nozzle can carried out automatically. Plural kinds of the suction nozzles at an actual use scope are set beforehand. When the suction nozzle is exchanged the flow amount range is changed over and selected with a respective suction nozzle. Plural kinds of the suction nozzles are selected and changed over automatically according to the dimension of a change amount of an operation condition. A brushless direct motor is used as the blower motor and has a domain being operated at a chopper control duty of factor 100%.

In a fluidic flowmeter for measuring the flowrate higher than the preset flowrate by use of a fluidic element and for measuring the flowrate lower than the present flowrate by use of a flow sensor inserted into the nozzle portion, the present invention relates to the fluidic flowmeter that has an abnormality judging circuit for judging an abnormality and issuing a warning signal and also zero point and gain correcting circuits when operating the flowrate on the basis for the signal being output from the flow sensor in the case that the flowrate signal higher than the preset flowrate is to be input only from the flow sensor side and in the case that the flowrate signal higher than the preset flowrate is to be input only from the flow sensor side and in the event that the flowrate signal lower than the preset flowrate is to be input only from the fluidic element side.

In a vacuum cleaner, both static pressure H.sub.data and a variation width .DELTA.H in the static pressure appearing when a suction port is operated are detected from a pressure sensor provided at a rear side of a filter within a main body of the vacuum cleaner; a current variation width .DELTA.pbi appearing when the suction port is operated is detected from a current of a nozzel motor for driving a rotary brush stored in a power brush suction port; an air quantity at the suction port is calculated from the current, rotational speed of a fan motor and static pressure; command values are newly obtained by performing a fuzzy calculation with the variation width .DELTA.pbi, static-pressure command value Hcmd; the variation width .DELTA.H and the static-pressure command value Qcmd; the variation width .DELTA.pbi and static-pressure command value Hcmd; and also the variation width .DELTA.H and static-pressure command value Qcmd as the input thereto; the rotational speeds of the fan motor and nozzel motor are controlled from the result of the command values; and further optimum air suction force is automatically obtained, depending upon the suction port under use and cleaning floor plane.
