Title: Transfer mask and its production
Inventor: AMAMIYA ISAO
IPC: G03F1/20
Filed: 1995-03-01
Abstract: PURPOSE: To obtain a mask having excellent stability and durability and high aperture accuracy and transfer accuracy without deterioration due to peeling of films or diffusion by forming a supporting frame part, a metal thin film part supported by the supporting frame part, and an aperture formed in the metal thin film part. CONSTITUTION: First, an etching stopper metal layer 2, a thin film metal part 3 and a SiO2 layer 4 are formed on the surface of a substrate 1. Then, the back surface of the substrate 1 is etched to the metal layer 2 while a supporting frame part 11 is left so that a thin film part 12 of the metal layer 2/metal layer 3 structure supported by the supporting frame part 11 is formed. Then, the SiO2 layer is patterned with a resist, and after the resist is removed, the patterned SiO2 layer 4 is used as a mask to perform perpendicular etching of the metal layer 3 to form an aperture pattern 13. By this method, a process to form a conductive layer which is generally used can be eliminated. Since no SiO2 intermediate layer is present, the obtd. mask has excellent heat radiating characteristics and high accuracy for the aperture and transfer can be obtd.

Filed: 1979-06-01
Abstract: PURPOSE:To eliminate malfunctions of the search preset operation just after band switching, by stopping counting of the counter, which controls a pulse width modulator, until the tuning voltage changes from the maximum value to the minimum value and becomes a normal value just after band switching. CONSTITUTION:At a switching time of search preset, the maximum value and the minimum value of the turning voltage are detected from the output of preset counter 7 by turning voltage maximum and minimum deciding circuit 14 for the purpose of changing the tuning voltage from the maximum value to the minimum value.

Filed: 1985-03-29
Abstract: PURPOSE:To avoid generation of ignition spark upon breakage of an engine, by providing first and second sensors generating different crank angle signals and hindering ignition according to generation of a crank angle signal from the second sensor. CONSTITUTION:If a forward end A of a projection of a rotor 1 starts to be reversely rotated from a position opposite to a first pickup 3 before a reverse end B of the projection reaches the first pickup 3 under forward rotation of the rotor 1 after starting, the reverse end B passes before a second pickup 20 upon leaving of the forward end A from the opposite position. At this time, a negative wave is generated from the first pickup 3, and almost simultaneously, a positive wave is generated from the second pickup 20. Then, transistors 22 and 23 are switched on by the positive wave to thereby hold a high level of an output at Q from a flip flop 6. Therefore, a transistor 7 does not go off, and a primary current of an ignition coil 8 is not cut. As a result, a high voltage is not generated in the secondary side of the coil to avoid ignition.
