IPC: C30B1/08
Filed: 1983-03-30
Abstract: PURPOSE:To get rid of a deflection error at a time of annealing and position detecting and to enable annealing at a high precision position by performing position detection of a pattern etc. with scanning an electron beam at the same value as a current value performing annealing. CONSTITUTION:An irradiation position designation of an electron beam is generated from a computer CPU, and is applied to D/A converters 10, 11 respectively through a control device 1. Moreover, they are converted to voltages by D/A converters 10, 11 and are applied to deflecters 8, 9 through amplifiers 12, 13. Accordingly it becomes a condition to irradiate the electron beam to the designated position. Then a signal to make the electron beam ''on'' is generated during specified time interval from the computer CPU, and is applied to amplifiers 12, 13 through the control device 1. And outputs from the amplifiers 12, 13 make the electron beam ''on'' during specified time interval. The specified time interval is the best time interval to perform annealing. As the current value of the electron beam at this time of annealing is equal to the value of the electron beam at the time of a pattern detection, an error at the operation is got rid of.

Title: Magnetic tape traveling device
Inventor: NAKAI TOSHIHARU
IPC: G11B15/61
Filed: 1989-03-07
Abstract: PURPOSE:To suppress the floating of a magnetic tape from a magnetic head by setting up the depth of a dynamic pressure group and a distance between a face opposed to the magnetic tape and the magnetic tape so that the pressure of an air film generated between the magnetic tape and a dynamic pressure generating member is higher than the pressure of an air film generated between the magnetic tape and the magnetic head. CONSTITUTION:The depth of a dynamic pressure group 5b and a distance between a face opposed to the magnetic tape 2 and the magnetic tape 2 is set up so that the pressure of an air film generated between the magnetic tape 2 and a dynamic pressure generating member 5 is higher than the pressure of an air film generated between the magnetic tape 2 and the magnetic head 1 at the time of traveling of the magnetic tape 2. The increased pressure of the air film due to the group 5b acts upon the tape 2 as dynamic pressure in the direction orthogonal to the traveling direction. Consequently, the separation of the magnetic tape 2 from the magnetic tape 1 is suppressed and a contact property between the tape 2 and the head 1 is improved.

Title: Method for limiting exhaust temperature of internal combustion engine operated under heavy load
Inventor: LANG ERNST-WALTER
IPC: F01N9/00
Filed: 1997-03-10
Abstract: PROBLEM TO BE SOLVED: To prevent an internal combustion engine and a catalyst in an exhaust system from being heated, by judging whether a first step for reducing an exhaust temperature during an operation under a heavy load is effective or not and, when the first step is not sufficient, by taking a second step for reducing the exhaust temperature. SOLUTION: When an internal combustion engine is operated under a heavy load, a first step is taken to change a composition of a mixture of fuel and air consumed in the internal combustion engine into a rich composition (S1, S2). When the first step is not effective, a second step is taken to reduce the output of the internal combustion engine (S4). For example, when the internal combustion engine has an electronic accelerator pedal, the maximum opening angle of a throttle valve may be limited and, when the internal combustion engine has a supercharger, an action of the supercharger may be reduced. With both steps, the amount of air taken by the internal combustion engine is reduced, which reduces the amount of supply of mixed fuel and finally reduces the amount of the generated by combustion.
