Title: Variable frequency division circuit
Inventor: ISHIKAWA TOMOYOSHI
IPC: H03K23/64
Filed: 1989-01-10
Abstract: PURPOSE:To obtain a variable frequency divider circuit whose frequency division value changes continuously in a range of total frequency division value NP+ A>=P<2>-P by devising a circuit such that a frequency division value varied continuously is obtained with respect to a frequency division value larger than total frequency division value = NP+A=P(P-1) in the case of total frequency division value = NP+A<P<2>. CONSTITUTION:For example, a switch 7 receives both an output signal of a variable frequency divider 3 and a signal inverting the output signal by an inverting circuit 6. Which of the output signal of the variable frequency divider 3 and the signal inverting the output signal is allowed to pass through is switched by using a control signal from a logic circuit 2 and the output signal of the switch 7 is supplied as the control signal of the 1/2 frequency divider circuit 5. Thus, in the case of total frequency division value = NP+A<P<2>, a frequency division value varying continuously with respect to the frequency division value larger than total frequency division value = NP+A=P(P-1) is obtained. Thus, the variable frequency divider circuit whose frequency division value varies continuously is obtained in the range of MP+A>=P<2>-P.

Title: Production of electrode for liquid crystal display panel
Inventor: NAGASAKI HITOSHI
IPC: G02F1/1333
Filed: 1981-01-14
Abstract: PURPOSE:To keep the voltage applied to each electrode of a panel at a certain level, by providing a metallic lead wire having a small width and a low resistance value on a transparent conductive film and thus avoiding the voltage drop caused by the resistance of the electrode film. CONSTITUTION:An Ni-P group bath of hypophosphite salt is preferably used for the electroless nickel plating both used at a lead wire part of a matrix panel in terms of the high adhesive strength to a transparent electrode film on a substrate and a low level of electric resistance. The thickness of the metallic skin requires 4,000Angstrom for the electrode at the data side and 1.6mu for the electrode at the driving side respectively. The heat treatment is preferably carried out for an hour at 200-400 deg.C in the air or in the N2 atmosphere in terms of the adhesive strength and the resistance value. It is possible to apply the nickel plating after a preprocess by which only the area on the transparent conductive film is selectively plated. This method can reduce the cost and increase the production efficiency in comparison with the vapor deposition method since no Au is used.

Abstract: PURPOSE: To keep the sealability excellent by demarcating the space in a fixed ring rearward of a circumferential groove in the fixed ring cut on the opposite side of a rotary ring, stretching an elastic film between the circumferential groove and the space, and exciting the elastic film to prevent the seizure. CONSTITUTION: An exciter 12 provided on a fixed ring 3 is energized and an elastic film before a movable part is excited to change the volume in a circumferential groove 10 communicated with a seal surface 14 of the fixed ring 3, and to push out the fluid into the clearance in the axial direction of the seal surface 14 or suck the fluid in the clearance. In the pushing stroke, the pressure in the circumferential groove 10 part is increased, the force to push the fixed ring 3 in the axial direction is increased, and the fixed ring 3 is detached from a rotary ring 2 to prevent the contact. In the sucking stroke, the pressure of the circumferential groove 10 part is decreased, and the clearance in the axial direction in the seal surface 14 is decreased by a spring 8 to bring the fixed ring 3 close to the rotary ring 2.  Thus, the clearance in the axial direction in the seal surface 14 can be changed, and the contact is prevented to obtain the stable sealability.
