Abstract:
To stabilize the illumination fluctuation rate of a short arc type discharge lamp of the type having a pair of electrodes disposed inside an arc tube in a manner of facing each other and a hydrogen getter, by absorbing hydrogen gas in an arc tube without causing a decline in the performance of the short arc type discharge lamp arising out of a hydrogen getter, the hydrogen getter is formed of a hollow container made of a material that allows the transmission of hydrogen with a getter material sealed tightly inside the hollow container, and a holder for the hydrogen getter is held on the electrode with the hydrogen getter fixed in the holder.
Abstract:
A short arc discharge lamp has improved starting properties in which there is no danger of damaging the arc tube that surrounds a discharge space and in which the radiant light from the arc tube is not adversely shielded. This is achieved by providing the short arc discharge lamp with a first electrode having an electrical potential and to which a high voltage is applied, and a second electrode opposite the first at a in spaced relationship. Additionally, in the discharge space, there is positioned at least one conductive component with a tip projecting into the discharge space. The conductive component has an electrical potential which is identical to the electrical potential of the first electrode and has a tip spaced a distance from the second electrode which is greater than the distance between the first and the second electrode.
Abstract:
It is an object to provide a xenon discharge lamp lighting device with few or no lamp startup lighting failures, even when a xenon discharge lamp is near the end of its useful life. In the xenon discharge lamp, when a lamp voltage increases, from the ending point of the rush current supply time period, occurring upon starting a xenon discharge lamp lighting igniter, for a preset specified time T, the input power is increased in accordance with the lamp voltage increase amount, whereby constant power control is provided thereafter.
Abstract:
An apparatus for controlling the operation of an automobile air conditioner comprises mode switches which permit selection between a manual control mode and an automatic control mode for the control of the flow rate of the conditioned air, and a digital computer incorporating therein a memory which memorizes the selected control mode in accordance with signals received from the mode switches. The digital computer is constituted to give instructions to control members of the air conditioner for controlling in accordance with the values stored in the memory, and to set in the memory a value representing the automatic control mode so as to operate the air conditioner in the automatic control mode when a main switch of the air conditioner is turned on.

The electronic control device includes various sensors, a microcomputer for executing computation processings of output signals from the various sensors in accordance with a predetermined program and producing a first and a second control signal, a drive circuit responsive to the first control signal for changing a temperature adjusting value of the heat exchanger and another drive circuit responsive to the second control signal for changing the cooling power of the cooling device, thereby to control the air temperature within the automotive passenger compartment at a desired value.
Abstract:
For stably supplying an electron emitting substance and preventing illuminance fluctuations, a cathode is provided made from a tungsten material containing an electron emitting substance and having a taper part a diameter of which becomes smaller towards a tip end, a tip end face formed at the tip end side of said taper part, and a fine hole extending from said tip end face in an interior of said cathode, wherein said fine hole is formed at said tip end face such that it extends over at least two tungsten crystal grains. The invention also relates to a short arc type discharge lamp comprising said cathode.
Abstract:
A discharge lamp of the short arc type having a trigger wire which can be installed in a state which is suitable for a directional capacity of the electrode regardless of what type of base the lamp has is achieved by the trigger wire on the outside surface of an arc tube having the following characteristic: an annular area that is formed by a portion of the trigger wire which is looped around the arc tube and elastically held against the outside surface of the arc tube; a first holding part which adjoins a first end of the portion of the trigger wire that forms the annular area and which extends in an axial direction along the arc tube; a second holding part which adjoins a second end of end of the portion of the trigger wire that forms the annular area and which extends in the axial direction along the arc tube.
Abstract:
A vehicle air conditioner control apparatus for supplying into the passenger compartment of a vehicle a flow of air which is temperature controlled in accordance with air conditioner control conditions, automatically controls an air change-over damper in response to a manual setting device for selectively commanding the induction of outside air, the induction of inside air and the induction of outside and inside air into an air duct and in response to a signal indicative of an absolute temperature of air inducted into the air duct, which is computed and generated in accordance with the outputs of a plurality of sensors.
Abstract:
A plurality of control modes set in consideration of the comfortability in a compartment of a vehicle are previously stored in a memory medium, such as a magnetic card, and programs of the compressor control, the recirculation/fresh air change-over control, the blow-out opening change-over control, the air flow rate control, the condensation prevention control and the like which are preset in a central processing unit are performed in accordance with the data of the aforesaid memory medium. Output signals from sensors provided at various portions of the vehicle or instructions by the operator, and various controls concerning the air conditioner are automatically performed without requiring manual operations. The controls can be effected through any one of a speech recognition device, sensors, external components and manual operations.
