Title: Rear focus type zoom lens
Inventor: HAMANO HIROYUKI
IPC: G02B15/20
Filed: 1989-06-09
Abstract: PURPOSE:To obtain excellent optical performance over the entire power variation range from a wide-angle end to a telephoto end while preventing the zoom lens from increasing in size by moving a 1st group to the object side and a 2nd group to the image plane side for power variation from the wide-angle end to the telephoto end, and moving a 4th group for the correction of image plane variation pertaining to the power variation and focusing it. CONSTITUTION:The power is varied from the wide-angle end to the telephoto end by moving the 1st group to the object side and the 2nd group with negative refracting power to the image plane side, and the 4th group with positive refracting power is moved to correct the image plane variation pertaining to the power variation and also perform focusing. Then, expression I - V is held for the focal length fi of an i-th group, the focal length fw of the whole system at the wide-angle end, the zoom ratio (z), the image formation power beta2T of the 2nd group at the telephoto end, and the movement quantities V1 and V2 of the 1st and 2nd groups at the time of the power variation from the wide-angle end to the telephoto end. Consequently, the whole lens system is reducible in size, excellent aberration compensation is attained over the entire power variation range, and the optical performance with small aberration variation is obtained.

Title: Process controller
Inventor: HATAKEYAMA MASAHIRO
IPC: G05B11/32
Filed: 1989-06-09
Abstract: PURPOSE:To prevent the occurrence of a change which causes a change of the controlled variable and to improve the controllability by obtaining the change value of the controlled variable caused by a 1st manipulated variable from a simulation arithmetic operation and then obtaining a 3rd manipulated variable corresponding to the obtained change value to subtract the obtained manipulated variable from the 1st manipulated variable. CONSTITUTION:A control change value arithmetic part 42 applies the correction to a detected disturbance signal Dn in consideration of the delayed time together with the correction of coefficient with use of a coefficient K2. Then the change value K2.Dn* is obtained for the controlled variable produced by a 1st manipulated variable via a simulation arithmetic operation and applied to a pressure change value detecting part 43. A PID arithmetic part 44 uses the value K2.Dn* as the control value to perform a PID arithmetic with the prescribed value defined as the target value SV. Thus a 3rd manipulated variable DELTAMVn* is obtained in response to the value K2.Dn*. Then the part 44 subtracts the variable DELTAMVn* from a 1st manipulated variable K1.DELTADn+En obtained by a feedforward control part. In addition, a 2nd manipulated variable En is added to the result of said subtraction. Thus it is possible to cope with occurrence of the disturbance via the feedback control.

Filed: 1990-06-06
Abstract: PURPOSE:To thin an optical disk element by combining plural thin planar members where a twisting part and a bending part are positioned on a plane including the rotational center of a movable part. CONSTITUTION:A supporting spring 2 is constituted of positioning the twisting parts 2A and bending parts 2B on the plane including the rotational center K and external force to respective parts can be simultaneously applied. Thereby, twisting deformation caused by couple of forces occurs on the twisting parts 2A of the spring 2 and bending deformation regarding the twisting parts 2A as action points occurs in the bending parts B based upon the twisting deformation. When the couple of forces occurs in the bending part 2B, the twisting part 2A acts as a twisting spring and the bending part 2B acts as a bending spring, so that the movable part can be obliquely rotated by generating twisting deformation in the twisting part 2A. Consequently, the device can be thinned.

Title: Precision positioning device
Inventor: KUWATA TORU
IPC: F16H25/20
Filed: 1987-06-15
Abstract: PURPOSE:To make it possible to perform precision positioning with high speed by providing a connecting member for connecting both ends thereof with a removal body and a slide table through respective universal joints and clamping the movable body and slide table via a spherical body. CONSTITUTION:A spring arm 12 is made flexible by the adjustment of a connecting rod in length so that a movable body 2 and a slide table 1, which are clamped by a spherical body 3 and arms 11, 21, are attracted to each other. This forms a pre-load condition for bringing the spherical body 3 into contact with the arms 11, 21 in the load as desired in the sliding direction. When the movable body 2 is made in a linear motion by a linear driving device 5, the movable body 2 pushes the table 1 and the spherical body 3 while pulling them through the connecting rod 4 so as to move the table 1. In this case, even if motion occurs to the movable body 2 in the radial direction and the motion around the shaft crosses orthogonally with the linear motion direction, they are absorbed by the rolling of the spherical body 3 and the universal joint 40 for preventing the motion around the shaft from transmitting to the table 1.

IPC: B63H19/00
Filed: 1988-06-16
Abstract: PURPOSE:To eliminate trouble such as production of gas, corrosion of electrode or water leakage by rotating a tubular electrode through thrust produced in the liquid contained in an outer tube then feeding current having different polarity from the electrode to a power supply converting mechanism in synchronization with the rotation. CONSTITUTION:Flux and current cross approximately in perpendicular to produce electromagnetic force in the axial direction of an electrode tube 11 thus thrusting while delivering liquid. Thrust of the liquid is received by the blade body 21 at a rotary bearing section 20 and the electrode tube 11 is rotated to contact the terminalboards of an integrally rotating power supply converting mechanism 51 alternately with a brush thus feeding positive and negative poles alternately to the electrode boards 13-16 of a pair of electrodes 17, 18. In other words, production of gas and corrosion of the electrode boards 13-16 can be prevented by feeding AC current. When the electrode tube 11 arranged rotatably in the outer tube 6 is rotated automatically with the thrust of liquid filled in the outer tube 6, water does not leak and no power is required for rotating the electrode tube 11 thus enabling supply of AC current to the pair of electrodes 17, 18.
