  • RESIST UNDERLAYER FILM FORMATION COMPOSITION
    Publication number: 20240103369
    Abstract: A resist underlayer film-forming composition that exhibits a high etching resistance, a favorable dry etching rate ratio and optical constant, and can form a film exhibiting a good coatability even to a so-called uneven substrate, providing a small difference in film thickness after embedding, and having planarity and a superior hardness; a resist underlayer film formed from the resist underlayer film-forming composition; and a method of producing a semiconductor device.

  • VEHICLE AIR CONDITIONERS
    Publication number: 20220250435
    Abstract: A vehicle air conditioning device is disclosed. The air condition device includes an air conditioning case having a passage in which air flows, a blower connected to the air conditioning case for blowing the air, a cooler and a heater housed in an interior of the air conditioning case, and a duct provided in the air conditioning case for conveying the air that has been temperature controlled by the cooler and the heater. The passage includes a cool air passage in which the cooler is disposed, a warm air passage in which the heater is disposed, and an introduction passage provided between the cool air passage and the warm air. A switching door is provided in the introduction passage for controlling an amount of the air flowing to the cool air passage and the warm air passage.

  • Vehicle lamp with discharge bulb
    Patent number: 5906428
    Abstract: A reflector 11 to which a discharge bulb 16 is attached is made of a conductive material, and a casing (turn-on circuit casing 30) made of a conductor is attached to a rear-side opening portion of a lamp body enclosing the reflector so that the opening is closed. A grounded shielding tube 21 is provided to enclose the discharge bulb 16, and a grounded extension reflector 3B is disposed at the opening of the reflector 11. At least the reflector 11 and the casing 30 are collectively grounded so that it becomes possible to suppress the electromagnetic waves radiated from the discharge bulb 16 to its circumference.
