Title: Exposure and device
Inventor: ONO KAZUHIRO
IPC: H01L21/027
Filed: 1996-05-02
Abstract: PROBLEM TO BE SOLVED: To suppress a change in the optical characteristics of a projection optical system and to make the throughput of an exposure treatment enhance by a method wherein the storage amount of heat, which is generated in the projection optical system by the incidence of illuminating light which is emitted from a light source, is monitored and the storage amount of heat is controlled so as to prevent the storage amount of heat from exceeding a previously set reference storage amount of heat. SOLUTION: As a thermal energy due to illuminating light 4 incident upon a projection optical system 6 is stored in the system 6, a reference storage amount of heat is previously set in a storage-amount-of heat control part 10 and the storage amount of heat in the system 6 is monitored at any time so as to prevent the storage amount of heat from exceeding the reference storage amount of heat, that is, the part 10 controls a illuminating light intensity control part 11 to adjust the intensity of the light 4, whereby the storage amount of heat in the system 6 is controlled. Therefore, a change in the optical characteristics of the system 6 can be suppressed. Accordingly, as the change in the optical characteristics is made fine, the optical characteristics, which are difficult in correction like a spherical aberration, a curvature of field and the like, are controlled and the optical characteristics can be maintained with high accuracy.

Title: Magnetic recording circuit device

IPC: G11B5/027
Filed: 1979-08-31
Abstract: PURPOSE: To facilitate variable bias control and variable frequency compensation by connecting a variable impedance circuit in parallel to a magnetic recording head at the output stage of a bias trapping circuit.  
     CONSTITUTION: Variable impedance circuit 44 consists of primary winding 48 connected in parapllel to head 31, secondary windings 49 and 50 transformer- connected to primary winding 48, and transistor TRs 51 and 52 connected in parallel to the secondary windings. Both TRs 51 and 52 are so driven that they will operate as variable impedance elements and, when a high-frequency signal is to be recorded, driven at a high voltage. As a result, each resistance value decreases and the impedance of primary winding 48 of transformer 46 also decreases. In consequence, a shunted current determined at the division ratio of both impedance values of winding 48 and head 31 is generated and as the mount of the shunted current to winding 48 increases, the bias current supplied to head 31 decreases to the contrary, thereby obtaining a bias current value suitable to the high-frequency signal. Consequently, the variable bias control and variable frequency compensation can be carried out easily.
