摘要:
A gas sensor has an elongated planar ceramic substrate carrying a gas-sensitive layer at one end thereof, and a ceramic layer overlaid on the substrate with a setback from the gas-sensitive layer so as to form a staircase-like step on the substrate, the setback edge surface of the ceramic layer being non-linear in the width direction of the substrate but preferably perpendicular to the plane of substrate.

A gas component detecting plug including a gas component-sensitive element, lead wires connected to the gas component-sensitive element, a tubular or board-like insulator which supports both the gas component-sensitive element and the lead wires, and an enclosure, the insulator being sealed to the enclosure so that the gas component-sensitive element is positioned on a leg portion side, characterized in that a spacer is disposed and retained in a gap formed between the insulator and the enclosure, in that a space on a head portion side formed by the insulator, enclosure, spacer and electrode wires is filled with glass and in that a rubbery elastic member having an insulating property is inserted in the head portion side. The gas component detecting plug is superior in water-proofness, gas-tightness, heat insulating property and productivity.

A method of producing a gas sensor is provided. The method includes a disposition step of preparing an elastic seal member having a main body portion and a smaller diameter portion that is smaller in outer diameter than the main body portion, disposing the entire main body portion and a part of the smaller diameter portion inside a tubular metallic member and allowing a remaining part of the smaller diameter portion to protrude outward from a rear end of the tubular metallic member, and a crimping step of crimping at least a portion of the tubular metallic member radially inward and thereby compressively deforming the elastic seal member. A gas sensor is also provided.

An air conditioning apparatus includes a variable frequency power source device for providing an AC electric power with a variable frequency, a variable capacity compressor driven by the AC electric ipower and a starting detector for detecting a starting state of the compressor a predetermined time after the compressor is energized. When the starting detector detects the starting failure of the compressor, the variable frequency power source device feeds the compressor with a starting frequency voltage until the starting detector detects changes in the level of the input current to the compressor within a predetermined time to heat refrigerant in the compressor, and then feeds the compressor with a driving frequency voltage corresponding to the required air conditioning load. When no change in the level of the input current is detected within the predetermined time, the variable frequency power source device supplys the compressor with the driving frequency voltage immediately after the predetermined time elapsed.

A gas sensor including an element 4 for measuring the concentration of a gas to be detected which is contained in a gas under measurement; a protector 2 provided to cover a tip end of the element 4 in the axial direction; and a protection cap 1 removably attached to the gas sensor. The protection cap 1 includes a tubular portion 106 which surrounds a side surface 202 of the protector 2, support portions 102 which project from an inner surface 161 of the tubular portion 106 and reach the side surface 202 of the protector 2 without axially partitioning the space between the inner surface 161 of the tubular portion 106 and the side surface 202 of the protector 2, and an air-outlet hole 103 for establishing communication between the interior and exterior of the protection cap 1.

An object of the present invention is to provide a mobile electronic device and an input method thereof, all of which are capable of canceling a restricting feature for preventing erroneous operations, and capable of quickly executing a desired feature. In a restricted state, in a case in which a control unit determines that a touch detected by a detecting unit is a first touching operation, the control unit cancels the restricted state, and causes a display unit to display a screen that was displayed before the restricted state, and in a case in which the control unit determines that the touch thus detected is a second touching operation, the control unit cancels the restricted state, and executes a predetermined function.

A heat-pump type refrigeration cycle includes at least a compressor capable of switching between cooling and heating modes. A first memory stores first reference temperature data for the cooling mode, and second reference temperature data for the heating mode. A second memory stores first set data for setting a cooling temperature and second set data for setting a heating temperature. A mode selector compares room temperature detection data with the first and second reference temperature data, in accordance with an automatic operation instruction, and outputs a first signal for selecting the cooling mode or a second signal for selecting the heating mode. A controller sets the heat-pump type refrigeration cycle in the cooling or heating mode, in accordance with the first or second signal, and controls the compressor in a drive state or a stop state, so that a comparison difference between the first or second set data and the room temperature detection data becomes zero. A monitor is connected to monitor the stop state of the compressor, and, when the stop state continues for a predetermined period of time or longer, to provide a re-selection instruction equivalent to the automatic operaiton instruction to the mode selector.

摘要:
A refrigeration cycle has a compressor, an outdoor rotary-type heat exchanger, a motor-operated expansion valve, and an indoor rotary-type heat exchanger which are sequentially connected to each other to circulate a refrigerant. A tank is set in a connected state or a non-connected state with respect to a refrigerant discharge side of the compressor. A detector detects at least a pressure at one side of each of the exchangers. A first controller sets the tank in a non-connected state when a normal operation of an air conditioner is to be started, and controls the capacity of the compressor, the rotational speed of the exchangers, and the opening degree of the valve in accordance with an air-conditioning load, thereby performing the normal operation of the air conditioner. A second controller causes the compressor to keep operating at a predetermined capacity until a detection pressure from the detector coincides with a preset value, when the air conditioner is to be stopped, and sets the tank in a connected state while controlling the valve to a predetermined opening degree, thereby recovering a refrigerant in the tank. A third controller rotates the exchangers at a predetermined speed when the air conditioner is to be started, and sets the tank in a connected state while controlling the valve to a predetermined opening degree, thereby filling the refrigerant in the exchangers from the tank.
摘要:
In a heat pump heating apparatus of this invention, a compressor included in a refrigerating cycle is operated at a speed corresponding to a blowoff temperature so that the temperature of air blown off into a room through an indoor fan from a condenser becomes close to a set value when a room temperature is less than its set value. The indoor fan is operated depending upon a room temperature, i.e., is operated under the state of a relatively great airflow when the room temperature is far lower than its set value and is operated under the state of a relatively small airflow when the room temperature is closer to its set value.
