Title: Low pass filter
Inventor: ABE TOSHIO
IPC: H03H11/12
Filed: 1985-12-18
Abstract: PURPOSE:To automatically set a high range cut-off frequency to a communication speed, by using an operational amplifier, frequency/voltage converter, and variable resistance element for a low pass filter. CONSTITUTION:An active filter is constituted of an operational amplifier 1 and impedances 2-5 and a variable resistance element whose resistance value can be changed by a voltage from the outside is used for the impedances 2 and 3. The variable resistance element is set in such a way that its resistance value RX can be in inverse proportional to a control voltage Vc from the outside. A frequency/voltage (F/V) converter 6 which input a reference clock fs for communication speed is provided and the resistance values RX of the variable resistance elements 2 and 3 are controlled by the output voltage of the converter 6. Therefore, a high range cut-off frequency fc goes to proportional to the reference clock fs and the input of a voltage/current converter 8 is made constant against the communication speed. As a result, the circuit current IL which is made to flow to a communication circuit, namely, a load resistance RL also becomes constant.

Title: Method for detecting deviation of pattern in printed circuit board
Inventor: SANO MASAO
IPC: H05K3/00
Filed: 1990-10-23
Abstract: PURPOSE:To detect the deviation of a pattern with a high accuracy by the fact that, when there is a deviation above a given magnitude in the pattern applied to the surface side of a printed circuit board, a land for detecting the deviation is brought into contact with an inner wall plating in the other through- hole and communicates with a second reverse side land. CONSTITUTION:When an inner diameter difference between a through-hole 12 and a land 16 for detecting a deviation is set to, for example, 0.1mm, the lands 13, 14, 16 and 18 and inner wall platings 15 and 19 are formed together with wiring patterns practically used when the wiring patterns are printed. When the deviation larger than 0.05mm is generated in this case, the land 16 is brought into contact with the inner wall plating 19 in the through-hole 12 and communicates with the second reverse side land 18 via the inner wall plat ing 19. Therefore, by bringing both the ends of an electric checker with the first and second reverse side lands 14 and 18, respectively, and examining whether both the lands 14 and 18 are short-circuited or opened, the deviation of the pattern can be detected.

Title: Production of dielectric film
Inventor: TOKI KAORU
IPC: H01G9/04
Filed: 1990-10-24
Abstract: PURPOSE:To stably produce the dielectric film of Ta oxide with good reproducibility by presputtering Ta as a target with Ar alone and then with a gaseous mixture of Ar and O2, and then subjecting the target to reactive sputtering with the gaseous mixture of Ar and O2. CONSTITUTION:A Ta target is subjected to reactive sputtering with a gaseous mixture of Ar and O2 as the sputtering gas to form a dielectric layer consisting of Ta oxide on a substrate. In this production of the dielectric film, sputtering is carried out in two stages prior to the normal sputtering. Ar alone is used in the first sputtering as the sputtering gas. Reactive sputtering is carried out as the second sputtering with the gaseous mixture of Ar and O2 as the sputtering gas. A shutter is then opened, and reactive sputtering is performed. Consequently, an abnormal discharge is not generated, and the dielectric layer of Ta oxide is stably obtained with good reproducibility.

Filed: 1987-11-10
Abstract: PURPOSE:To prevent the high voltage of a primary circuit from affecting a control circuit and to facilitate the inspection of each circuit and the connection of electric wires together with an overall compact structure of a controller by attaching the primary circuit for load control and the control circuit for primary circuit to a base and a cover respectively. CONSTITUTION:A primary circuit 3 for load control is attached to a base 1 and a control circuit 4 for the circuit 3 is attached to a cover 2 with a partitioning wall 16 put between both circuits. Thus the circuit 4 is kept away form the circuit 3 of high voltage with safety secured and also the thermal effect reduced. Furthermore the inspection and maintenance are facilitated with both circuits 3 and 4 with removal of the cover 2. Then the function of the circuit 3 can be changed in accordance with various needs with no change of the circuit 4. Thus the attachment/connection jobs are also facilitated since the cover 2 is attached at the front of a controller after the base 1 is attached to a construction material and an electric wire is connected to a terminal board 34. At the same time, the size of the controller is reduced in comparison with a constitution where both circuits 3 and 4 set side by side.
