An apparatus and method for forming an integrally-shaped brake disk for a vehicle. The method comprises heating the brake disk material, and maintaining the material heated while it is inserted between upper and lower dies of the apparatus. The central and outer peripheral portions of the material are pressed and held. The intermediate portion between the central and outer peripheral portions is drawn and shaped by relative motion between the dies. The material is continuously quenched while it is maintained pressed and held.

In an optical head moving device, there is provided a pair of parallel, spaced apart guide members having the axes thereof lying on a common plane. A movable member having engaging portions engaged with the pair of guide members and a connecting portion connecting together the engaging portions is provided on the guide members. An optical head for focusing a light beam introduced thereinto is securely mounted on the movable member in such a manner that the emergence-side principal point of the optical head lies on the plane containing the axes of the pair of guide members. Means is provided for introducing a light beam into the optical head. Mover means is provided for moving the movable means with the engaging portions thereof in engagement with the guide members, to thereby move the optical head.

A particle level varied depending on a drying processing condition can be suppressed to be stably lowered. A batch type substrate processing apparatus include a cleaning processing unit 62 having a cleaning tank 69 that stores therein a cleaning solution for cleaning a substrate, and a drying processing unit 61 disposed above the cleaning tank 69 and having a drying chamber 65 configured to perform therein a drying process on the substrate. Based on a previously investigated relationship, an internal temperature of the drying chamber is set as an internal temperature of the drying chamber when loading the substrate thereinto corresponding to the batch size of a next batch process performed in the drying chamber, and the internal temperature of the drying chamber is adjusted to be identical to the set internal temperature of the drying chamber before loading the substrate into the drying chamber.

A substrate processing apparatus that performs processing by immersing a substrate into a processing liquid obtained by mixing phosphoric acid with a diluent includes a concentration sensing means for sensing the concentration of the processing liquid by measuring the absorbance characteristics of the processing liquid. The concentration sensing means includes a light-transmitting section that introduces the processing liquid into the inside to let the processing liquid pass therethrough, a light-emitting section that radiates light having a predetermined wavelength to the light-transmitting section, a light-receiving section that receives the light therefrom via the light-transmitting section, a first lens that condenses the light emitted from the light-emitting section to the light-transmitting section, a second lens that condenses the light that has passed through the light-transmitting section to the light-receiving section, and a cooling mechanism that cools at least one of these.

An evaporator unit includes an evaporator configured to evaporate a refrigerant, and a capillary tube configured to decompress the refrigerant. The capillary tube has two longitudinal ends bonded to the evaporator. At least one position of a middle portion between the two longitudinal ends of the capillary tube is fixed to the evaporator by press-contacting the evaporator. Therefore, it can prevent a crack from being caused at the bonding portions of the two longitudinal ends of the capillary tube.

A common electrode plate formed on a common electrode base attached to the lower surface of the movable stage faces a split electrode plate formed on a split electrode base attached to the upper surface of a main base, which are apart from each other at a predetermined interval. A support mechanism formed of ball bearings, ball stoppers at the movable side, steel balls, ball stoppers at the fixed side, and ball bearings allows the movable stage to move in directions of the X-axis, Y-axis and turning. A linear actuator 19 is driven to move the movable stage in the directions of X-axis, Y-axis, and turning.
