Title: Hard mask for shadow mask and manufacture thereof
Inventor: ISHIKAWA SATOSHI
IPC: H01J9/14
Filed: 1999-05-25
Abstract: PROBLEM TO BE SOLVED: To facilitate size enlargement and to improve quality as a photomask by providing a metal film pattern and an electroless plated film formed to cover the upper face and side faces of the pattern, on a support board transparent for ultraviolet rays. SOLUTION: A metal film pattern can be formed by forming a metal film mainly composed of metal selected out of Cr, Cu, Ni and Fe, in vacuum by a method selected out of sputtering, vapor deposition and ion plating, and etching it. An electroless plated film can be composed of one or more kinds of elements out of Ni, P, Co, Cr, Mn, Zn, W, Mo, Cu and sericite, or a eutectoid with sericite. With this constitution, etching of the metal film formed by electroless plating is dispensed with, so that a mask pattern of high quality can be obtained, and vacuum suction time can be sufficiently shortened because of large unevenness of pattern cross section.

A shift register 42 is stored with comparison results for the compensation period and an AND circuit 43 outputs the compensation start signal 2 when detecting the continuation of silence for the compensation period T. In this constitution, when the nonsound period is as long as the period T, the AND circuit 43 outputs a signal with a level ''1'', which is used as the compensation start signal. The compensation start signal 5 for a sound recording system is obtained associatively with a power source switch, etc.

Abstract: PROBLEM TO BE SOLVED: To easily pull out a lead, and to prevent the sharp increase of manufacturing costs by including a piezoelectric body on whose upper and lower faces electrodes are formed, changing the polarization density of the piezoelectric body, and weighting in a slice direction. SOLUTION: A temporary electrode 12 constituted of plural band-shaped electrode elements extended along an X direction is formed on the upper face and lower face of a plate-shaped piezoelectric body 10 so that electrode density can be gradually decreased from the central part of the piezoelectric body 10 to the right and left edge parts of an Y direction by a spatter method or the like. In this case, the X direction is the longitudinal direction of the piezoelectric body 10, and made equivalent to an electronic scanning direction, and the Y direction is the slice direction of the piezoelectric body 10. Next, a DC voltage is impressed between the two temporarily electrodes 12, and a polarization processing is operated. Afterwards, the two temporarily electrodes 12 are removed by, for example, an etching processing, and a main electrode is formed instead.  Thus, an ultrasonic diaphragm can be assembled by using the piezoelectric body in which the main electrode is formed.

Title: Output offset control circuit for full step direct-coupled amplifier
Inventor: YOKOYAMA KENJI
IPC: H03F1/34
Filed: 1978-11-28
Abstract: PURPOSE: To obtain an output offset control circuit featuring a reduced amount of the gain variation or distortion by giving the control to voltage V gs  between the gate and the source of the amplifier element of the differential amplifier based on the shift of the output offset in the full step direct-coupled amplifier.  
     CONSTITUTION: The input signal to terminal 26 is amplified through the differential amplifier circuit consisting of FET27 and 29 plus amplifier 31 and then delivered through terminal 36. The output voltage is fed back to the gate of FET29 and at the same time monitored by the differential amplifier circuit comprising transistors Tr38 and 41. When some output offset shift occurs at terminal 36, the shift is delivered to comparator 43 in the form of the difference of the collector potential between Tr41 and 38. In response to this, circuit 43 varies the drain current of FET46 and 47 to then vary the junction temperature. Thus voltage V gs  of thermocoupled FET29 and 27. The change of V gs  is cuased by the temperature characteristics of FET29 and 27, and as a result the change is avoided for the occurrence of the distortion or the gain due to the change of the driving current. Thus the output offset shift can be corrected.
