Title: Material for manufacturing fine circuit
Inventor: SANO KOICHI
IPC: H05K3/00
Filed: 1990-02-19
Abstract: PURPOSE:To enhance density by decelerating etching of a second metal layer disposed outside, relatively accelerating an etching speed when etching is advanced to a first metal layer disposed inside, and disposing the etching surface of the first layer of the inside near a base film substantially perpendicularly to the film. CONSTITUTION:A metal layer 11 provided on a base film 10 is formed at least of two types of metal layers 11A, 11B. The layer 11A is provided at the side near the film 10, the layer 11B is disposed thereon, and formed of a material having a slower etching speed than that of the layer 11A. Further, etching resist 12 for forming a predetermined circuit pattern is provided on the layer 11B. Thus, when a board material 13 made of the films 10, the layers 11A, 11B is etched, the layer 11B is initially etched at a slow speed, and when the etching is advanced to the layer 11A, and the speed is decelerated. As a result, an etching surface (a) near perpendicular to the film 10 is generated.

Title: Method for controlling ion-exchange reaction
Inventor: FURUNO NOBUO
IPC: B01J47/14
Filed: 1986-02-21
Abstract: PURPOSE:To use the capacity of an ion exchanger to the maximum by detecting the difference in conductivity between the processing liqs. before and after a reaction tower, and controlling the flow rate of the processing liq. in response to the detected value. CONSTITUTION:A liq. is initially passed at an optional SV value, and the change with time in the conductivity of the processing liq. is observed before and after the reaction tower. When the difference in conductivity is not changed or tends to increase, the SV value is progressively increased, and the SV value is increased immediately before the difference in conductivity begins to decrease. The SV value is decreased in the opposite case. when the liq. is continuously passed at the same SV value, the difference in conductivity decreases as the capacity of the ion exchanger decreases. The SV value is correspondingly reduced, and kept at a new critical SV value at which the maximum efficiency at that time can be obtained. The time necessary for removing the total amt. of ions is reduced to the minimum in this way, and the ion exchanger is used to the maximum of its capacity.

Abstract: PURPOSE:To reduce noise at a time of an idling operation by setting plunger speed for the rotating angle of a cam desk at a high speed range for the first stage, a low and constant speed range for the intermediate stage, and the fastest speed range for the remaining stage. CONSTITUTION:The rotation of a rotating shaft 1 rotates a roller holder 8 which has a roller ball 9. And a plunger 6 having a cam desk 7 reciprocates right and left at a speed corresponding to the surface shape of the cam desk while the ball 9 slides on the cam desk 7. And for the cam rotating angle from 0 to theta1, a plunger speed is set in a high speed range so as to inject fuel quickly. Further, for the cam rotating angle from theta1 to theta2, the plunger speed is set at a constant and low speed range allowing an idling operation to be effected. For the cam rotating angle from theta2 to theta3, the plunger speed is accelerated, but for the cam rotating angle exceeding theta3 upto theta4, the speed is decelerated. From that time on, the speed is accelerated until the cam rotates up to a reference position. Fuel is injected at a high injection rate for the angle range from theta2 to theta4 so as to secure the necessary power. thus, noise at a time of the idling operation is reduced and the fuel injection of a high performance is attained.

Filed: 1978-03-31
Abstract: PURPOSE:To obtain high resolution while maintaining a high reference frequency by changing over outputs of respective stages by using a ring counter for a pre-scaler part in a PLL circuit. CONSTITUTION:For example, the division ratio of variable divider is set to three. The output of voltage control oscillator 1 is divided by pre-scaler 2' of two in division ratio and  inputted to four-stage ring ocunter 7. Signal selector circuit 8 selects signal Q1 of counter 7 and transmits it to divider 3. Divider 3 outputs three pulses Q1 and this output signal is processed by selection control circuit 9 to switch the input of circuit 8 to Q2. By three pulses Q2, Q3 is selected in the same way, and at every time of the execution of divider 3, the output of counter 7 is switched in the order of Q1, Q2, Q3, Q4, Q1... Therefore, the output signal of circuit is shifted by a quarter period at each joint to allow divider 3 to operate as if having a 3+1/4 division ratio. Consequently, high resolution can be obtained without requiring a high-speed circuit while maintaining a high reference frequency.
