  • Publication number: 20070204635
    Abstract: By studying or storing refrigerating cycle characteristics of an air conditioning apparatus at the normal time and comparing them with refrigerating cycle characteristics acquired from the air conditioning apparatus at the time of operation, it becomes possible to exactly and accurately diagnose normality or abnormality of the air conditioning apparatus under any installation conditions and environmental conditions, which eliminates operations of inputting a difference between apparatus model names, a piping length, a height difference, etc at the time of apparatus installation. Accordingly, it aims at shortening the time of judging normality or abnormality, and improving the operability.

  • Publication number: 20070204927
    Abstract: [Problems] In a reduction in fluid pressure pulsation, a large space has been required for liquid expansion and a larger pressure loss has been involved. [Solving Means] A pressure pulsation reducing device has a flow path through which pressure pulsation is transmitted, an inner tube placed in the flow path and constructed so that most part of fluid flowing inside the flow path flows around the inner tube, and small holes provided in the inner tube for expelling jet flows into the flow path by a pressure difference between the inside and the outside of the inner tube. The jet flows are expelled from the inner tube to a contracted flow section provided around the outer periphery of the inner tube to reduce pressure pulsation of the contracted flow section.

  • Publication number: 20070052371
    Abstract: A discharge lamp ballast is designed to limit or interrupt its AC output power to the discharge lamp upon occurrence of an abnormal discharge outside of an arc tube. A detector is included to examine a lamp voltage once in each of the positive and negative half-cycles or in each one complete cycle of the AC output power, and identifies the abnormal discharge when there is a particular change in the monitored lamp voltage. The particular change may be defined by a single logic or by combination of several logics each designed to represent specific characteristic for the abnormal discharges of several types.

  • Publication number: 20070031138
    Abstract: Mobile equipment includes LEDs supplied with a current to emit red light, green light and blue light, FETs and a booster circuit for controlling the current supplied. The current supplied is controlled to supply all of the LED with a current of a low level to illuminate an object in a shooting mode with light for illumination. Thus in the shooting mode a white spot light illuminates the object, and the object can clearly be confirmed. At the moment of shooting, a current supplied can be increased at a burst to emit white flashlight to illuminate the object. A satisfactory image can thus be obtained. The source of light for illumination can be formed of miniature, light-weight LED, and does not impair in mobility mobile equipment having the source of light incorporated therein.

  • Publication number: 20050280491
    Abstract: There is provided a joint structure of a wound iron core in which iron core characteristics can be enhanced by improving the distribution of magnetic flux within an iron core. A wound iron core is formed to provide a joining structure or a butt joining structure and a lap joining structure disposed in an appropriate arrangement in which the a margin of overlapping is more increased as being closer to an outer periphery from an inner periphery of the iron core, taking a distribution of magnetic flux density within the iron core into consideration.

  • Patent number: 6330979
    Abstract: In a vehicle air conditioner where a foot mode and a foot/defroster mode can be set, when a target temperature of air blown into a passenger compartment is higher than a predetermined temperature, the foot mode is selected. However, even if the target temperature of air is higher than the predetermined temperature, the foot/defroster mode is selected in place of the foot mode when an outside air temperature is lower than a predetermined temperature and when a vehicle speed is higher than a predetermined speed. In the vehicle air conditioner, because the foot/defroster mode can be suitably automatically selected based on a fog-generation condition of a windshield, both fog-preventing performance of the windshield and heating performance of the passenger compartment are improved during heating operation.

  • Patent number: 6325104
    Abstract: A hydraulic circuit of the present invention comprises a single pump, a precedence valve connected to a discharge pipe of the pump and having a high-pressure side output port and a low-pressure side output port for respectively distributing pressure oil to a high-pressure side circuit and a low-pressure side circuit, a high-pressure specified operation valve connected to one of the output port of the precedence valve, an actuator connected to the high-pressure specified operation valve, a pressure reducing valve connected to the other output port of the precedence valve, low-pressure specified operation valves connected to an output port of the pressure reducing valve, and another actuator connected to the low-pressure specified operation valves. When a load is applied to the actuator connected to the high-pressure specified operation valve, the pressure oil from the pump is supplied to the high-pressure specified operation valve with higher priority.
