Title: Inspection assisting device
IPC: G11B33/00
Filed: 1992-03-25
Abstract: PURPOSE:To enhance the time efficiency of an operator, etc., and to enable smooth adjustment and inspection by providing an inspected tape transferring means and a cassette unloading means and cassette loading means respectively on the upstream side and downstream side thereof and inspecting at intermediate position thereby. CONSTITUTION:The cassette loading means 5 maintains a tape guide plate 13 in the specified position with a VTR 1 according to the position of the VTR 1 by a positioning roller 12. A plate 13 holds guide parts 13a, 13b and the tape cassette for inspection can be surely inserted into a cassette insertion port 1a of the VTR 1 even if the position of the VTR 1 deviates. On the other hand, the cassette unloading means 4 returns the cassette 8 mounted by the means 5 from the VTR 1 transferred after the end of the inspection by an operator to a taking out means 3. The operator makes inspection in the position between the means 5 and 4. The operator is thus able to concentrate upon the inspection without requiring the labor for the operation to insert the cassette 8 and the operation to take out the cassette. Then, the time required for the inspection stage is shortened.

Title: Power system controller
Inventor: KOMATA TAKAO
IPC: G06Q50/06
Filed: 1994-03-10
Abstract: PURPOSE:To provide a power system controller for operating a power system optimally by handling the control operation of a plurality of power systems totally thereby optimizing the power systems for multiple purposes. CONSTITUTION:Status amounts of a power system 12 are inputted through a system status amount collecting means 1 and a system status amount calculating means 3 and the sensitivity of objective expression of each control operation for each machine is determined by a sensitivity calculating means 6. An operating amount determining means 7 decides whether there is an operation for improving all objective expressions based on the sensitivity thus determined. If there is no such operation, the current state represents an optimal solution. If there is such operation, the means 7 determines a final operating amount while considering whether the operational regulations are violated or not by that operation and whether the operation is practical or not. Consequently, a system state where the objective expressions are optimized simultaneously when a plurality of control operations are independent from each other can be realized.

Title: Vapor growth method
Inventor: HABUKA HITOSHI
IPC: C30B33/12
Filed: 1995-03-01
Abstract: PURPOSE: To surely manufacture an epitaxial wafer having a flat surface which is free from micro-roughness by raising the temperature of a single-crystal silicon substrate in an inert gas atmosphere and etching off a natural oxide film formed on the surface of the substrate with a hydrogen gas before starting vapor growth. CONSTITUTION: After a substrate 1 is carried in a reaction vessel 3, the temperature in the vessel 3 is immediately raised in an argon-gas atmosphere until each temperature condition is met. When each temperature condition is met, the atmosphere is replaced with a hydrogen-gas atmosphere. Then, after a natural oxide film formed on the surface of the substrate 1 is completely removed by maintaining the substrate 1 for two minutes at 100 deg.C in the hydrogen- gas atmosphere, a thin film 2 having a thickness of about 6μm is grown on the surface of the substrate 1 within two minutes at a growing temperature of 1,100 deg.C by using trichlorosilan as gaseous material. When the inside of the vessel 3 is changed to the hydrogen-gas atmosphere at 1,000 deg.C and 1,100 deg.C, such a state that the surface of the substrate 1 is etched is hardly observed.

Title: Magnetic head device
Inventor: MURAGATA MASAKI
IPC: G11B20/20
Filed: 1986-03-27
Abstract: PURPOSE:To minimize an azimuth by delaying signals from respective heads so that the phases of signals from plural laminated reproduction heads can be the same. CONSTITUTION:The laminated reproduction heads A-C function as a reproduction head independently and comprise one reproduction head unit. After the read signals available from the heads A-C are delayed by delay circuits 22-24, (fixed delay time 23, variable delay time 22, 24 they are added by an adder circuit 25, and turn out to be reproduction signals through a reproduction amplifier 27. With the signal from the circuit 23 as a reference a delay time control circuit 26 controls the phases of the signals from the circuits 22 and 24. When all the phases of the signals outputted from the circuits 22-24 are the same, a signal obtained by totaling said signal becomes maximum. Therefore the circuit 26 controls a delay time control signal so that a signal passing through the circuit 25 can be maximum. Thus an azimuth can be minimized even if an error between the azimuths of a piece of data recorded on a recording medium is present.
