Title: Field-effect transistor
Inventor: KOBAYASHI JUNICHIRO
IPC: H01L29/812
Filed: 1990-10-29
Abstract: PURPOSE:To decrease parasitic capacity, prevent change and decrease in a high-frequency characteristic, and improve the characteristic by forming a connection between a gate electrode and a bonding pad floatedly on a conductive semiconductor region. CONSTITUTION:A connection 8 between the gate electrode 3 and bonding pad 7 of an FET is formed floatedly on a conductive semiconductor region 2. Therefore, the low-dielectric-constant air or insulating layer between the region 2 and the connection 8 decreases the parasitic capacity thereat. Thereby the parasitic capacity is changed less by the change of a mesa etching line to form the region 2, therefore, the characteristic scatters less. A shorter gate improves the high-frequency characteristic of the transistor. A construction that a source electrode 4 communicate with a lower part of the connection 8 prevents decrease in the mutual conductance and improves the characteristic.

Abstract: PURPOSE:To easily set the drop height according to interior angles of a polygonal cylindrical body by longitudinally, continuously and coaxially connecting a plurality of cylindrical bodies whose inside sectional shapes are formed into a polygonal shape in a rotational part of an incinerator, and providing a flat surface part of one mutually adjacent cylindrical body so as to be positioned on the corner part of the other mutually adjacent cylindrical body. CONSTITUTION:The hollow part section is circularly surrounded in an input part 5 by incinerating parts 6, and mud-like undefined refactory material is poured into the enclosure, so as to form a block 7 whose hollow part section is circular. Moreover, the incinerating parts 6 are sectioned into a plurality of parts, so as to hexagonally surround the hollow part section, so as to form a block 8 whose hollow part section is a hexagon. The hollow part section formed in such a way is formed by forming a side part 9 of one of blockes of the mutually adjacent hexagonal blocks and a step 11, so as to be positioned adjacent to the corner part 10 of the other mutually adjacent block. Thereby the drop height can be set according to the interior angles of the polygon, and the amount of articles to be incinerated to be accumulated in a weir part 12 can be suitably set.

Title: Thickness-shear ceramic oscillator substrate
Inventor: MATSUMOTO IKUO
IPC: H03B5/32
Filed: 1996-11-05
Abstract: PROBLEM TO BE SOLVED: To reduce the dispersion in an oscillating frequency of an oscillator, resulting from the presence of a nonvibrating region in the vicinity of a short side of the thickness-shear ceramic oscillator substrate. SOLUTION: Electrodes 12, 13 with a width being about 2/3 of a substrate width are formed from one end of the substrate 11 to the other end, along with a longer side of the substrate 11 not adjacent to each other at both sides of the thin and long rectangular substrate 11 made of a PZT to form a basic building block. A middle part of the width of the substrate on both sides of which electrodes 12, 13 are opposed to each other acts as a vibrating region 14, which is formed along the entire length of the substrate at a prescribed width of nearly 1/3 of the substrate width. The electrodes 12, 13 are formed through vacuum vapor-deposition of a metal by using a mask, and parts of both sides of the substrate 11 masked by the mask are limited to small regions at the four corners of the substrate.  Thus, the parts causing the defective electrodes 12, 13 are limited to the small regions at the corners, to reserve the vibrating region 14 in the vicinity of the short sides of the substrate. For the convenience of electric connection of the oscillator obtained by slitting the substrate, the electrodes on both sides of the substrate are extended up to the side faces.

Title: Automatic channel selection circuit
Inventor: NAKAMURA EIJI
IPC: H04N5/44
Filed: 1992-10-30
Abstract: PURPOSE:To provide an automatic channel selecting circuit capable of surely executing channel selecting operation even in an electric field of low intensity by shifting AFT voltage to a lower direction when AGC voltage is larger than a prescribed value. CONSTITUTION:Since the AGC voltage exceeds a reference value (e.g. 8V) when an input to an antenna is an electric field of low intensity (e.g. <=30dB), a transistor TR1 is turned on and resistors R2, R3 are validated. Thereby AFT voltage outputted from the serial node of a resistor R1 is shifted to the lower direction by the resistors R2, R3. The shifted AFT voltage is inputted to a microcomputer 14, which executes a prescribed operation. Since the AFT voltage is shifted to the lower direction by a shifting circuit 16, its level becomes surely lower than a reference value Vcc/2, so that searching operation can surely by executed.

Abstract: PROBLEM TO BE SOLVED: To make it possible to set a track width of a magnetic gap always with an accuracy with respect to an assembly standard by making it possible to accurately position a 1st core half and a 2nd core half. SOLUTION: A position of a 1st positioning part 15a is set at a predetermined distance with respect to a reference position, and a 2nd positioning part 15b is shifted to the side of the reference position from the positioning part 15a. The side faces (1) of the 1st core halves 2L1 and 2R1 are positioned by the positioning part 15a, and the side faces (2) of the 2nd core halves are shifted to the reference side. Therefore, the end parts (3) of the track widths TwL and TwR are positioned with respect to the above side faces (1). Moreover, if the widths of the 2nd core halves 2L2 and 2R2 are made wider than the 1st core half bodies 2L1 and 2R1, it is also possible to determine the track width.
