Abstract: PURPOSE: To continuously form a conducting line in such a manner that it can be connected with a constituent element in a crossover region. CONSTITUTION: Thin film structure 34 has conducting lines 12 and 14 which intersect with each other in a crossover region. A first insulating layer 40 covers the first conducting line 12.

IPC: G11B15/087
Filed: 1982-06-02
Abstract: PURPOSE:To attain an excellent still picture, by generating an AND output to a tape only for a reproducing track for stopping the capstan drive driving the tape in a low speed with this output. CONSTITUTION:When a switching signal is changed over to a still mode, a gate 3 is interrupted and gates 6, 12 are conductive. A motor control signal passes through the gates 6, 7 to drive a capstan motor 5 in a low speed until the gate 7 is interrupted via a motor drive circuit 4 and a tape is moved little by little. A head switching pulse (d) passes through monostable multivibrators 8, 9 and becomes a detecting pulse (e). On the other hand, an output voltage (f) from a reproducing head is a signal (g) through a level discriminator 11 and a gate. A monostable multivibrator MM13 is triggered with the signal (g) to form a pulse (h). When the pulses (h) and (e) are coincident, the gate 7 is closed and the motor 5 is stopped.

Title: Irradiation system for electron beam device
Inventor: YANAKA TAKASHI
IPC: H01J37/252
Filed: 1983-05-30
Abstract: PURPOSE:To facilitate adjustment operation and suppress an angle of convergence fully small by setting the reduction ratio of a front objective lens below a specific value and comprising a focusing lens so as to reduce an electric beam high efficiently. CONSTITUTION:A focusing lens system is comprised with focusing lenses C1, C2, and C3 and the reduction ratio by a front objective lens body L1 is set to less than 1/20. The focusing lenses C1 and C2 focuss the pictures P1 and P2 of an electron beam source at two stages and the picture ratio of the electron beam source is reduced high efficiently. The focusing lens C3 varies the focal point distance so that the picture P2 focused by the focusing lens C2 can be focused at the conjugate points with regard to the front objective lens body L1 of a sample Q. A variable diaphragm S that regulates the angle of convergence of an electron beam is provided near the lens surface of the focusing lens C3. As a result, since the reduction ratio of the front objective lens body is set to less than 1/20, an electron probe with extremely small diameter can easily be focused corresponding to the recess and protrusion of a sample and the angle of convergence can be made fully small.

Title: Pellicle
Inventor: HAMADA YUICHI
IPC: G03F1/62
Filed: 1993-04-22
Abstract: PURPOSE:To prevent deposition of foreign matter on a pellicle by using a conductive material as a separator for an adhesive to fix the pellicle on a mask substrate. CONSTITUTION:The separator for an adhesive to fix a pellicle to a mask substrate consists of a conductive material. Any conductive material can be used as far as to prevent generation of electrostatic charge, and for example, plastics compounded with a metal powder or carbon black as an agent to give conductivity are used. It is more preferable to use a metal foil having smooth surface which can be easily cleaned. As for the metal foil, copper foil, aluminum foil, stainless steel foil, etc., are used. By this method, even when the separator is brought into contact with other material and rubbed, no electrostatic charge is produced. Thus, deposition of foreign matter caused by electrostatic force is prevented.

Abstract: PURPOSE: To provide a noise reducing device capable of obtaining a large and stable noise reduction effect and evading enlargement is size and increase in weight of a camcoder. CONSTITUTION: When a sensor 7 detects a signal deeply correlative with the noise of the camcoder main body, an adaptive FIR filter 11 generates a cancel signal becoming a sound of a phase opposite to and the same sound pressure at the noise on the basis of the signal, and an adder 15 synthesizes the cancel signal with a noise signal from an incorporated microphone 2. A coefficient renewal means 16 calculates and updates successively the coefficient of the adaptive FIR filter 11 so that the reducing amount of the noise becomes maximum on a remaining signal caused as the result of the synthesis by the adder 15. By using an active method as the means reducing the noise of the camcoder, the enlargement in size and the increase in weight of the camcoder main body are evaded, and the large noise reduction effect is obtained.  Since the method reducing the noise by adding the noise signal in the stage of an electric signal with the cancel sound signal is used, the stable noise reduction effect is obtained.
