Title: Lens barrel for zoom lens
Inventor: TANAKA HITOSHI
IPC: G03B17/04
Filed: 1988-09-26
Abstract: PURPOSE:To compactly constitute a lens barrel by providing a driving cam for driving to move forward and backward a second lens group supporting frame in the optical axis direction relatively against a first lens group supporting frame so that each lens group can be interlocked and moved, while controlling an interval between each lens group at the time of zooming. CONSTITUTION:By rotating a driving ring 22, a first lens group supporting frame 3 is driven to move forward and backward in the optical axis direction, a first lens group 1 is transferred out or transferred in, and simultaneously, a driving cam fitted and attached to the first lens group supporting frame 3 is driven to rotate by a motion of the driving ring 22. As a result, by interlocking with the movement of the frame 3, a second lens group supporting frame 4 moves forward and backward relatively in the optical axis direction against the frame 3. Accordingly, while zooming is executed, an interval between first and second lens groups 1, 2 is determined by only a rotation angle of a driving cam cylinder 10. Also, a guide pin 13 provided projectingly on the frame 4 is always pressed against the driving cam by an energizing means 14. In such a way, the interval between the lens groups is controlled with high accuracy without being varied.

Title: Magnetic recorder
Inventor: KONDO YOSHIHIRO
IPC: G03G19/00
Filed: 1989-09-19
Abstract: PURPOSE:To prevent a magnetic fluid from attaching to parts other than a magnetic latent image part by bringing the surface of a movable body into contact with that of the magnetic fluid only in the part where a magnetic latent image is formed. CONSTITUTION:A writing head 14 sequentially writes prescribed magnetic patterns on a magnetic layer 11 to form a magnetic latent image. When the magnetic latent image part comes right above the magnetic fluid 21a by turning a movable body 13, the liquid surface of the magnetic fluid 21a is raised due to magnetic force acting between the magnetic layer 11 at the part where the magnetic latent image is formed and the magnetic fluid 21a. Consequently the magnetic fluid is stuck to the surface of the movable body 13 at the part where the magnetic latent image is formed to perform development. Since magnetic force does not act between the part where no magnetic latent image is formed and the magnetic fluid 21a, the fluid is hardly stuck. Thus, recording quality is improved.

Title: Pressure vessel
Inventor: ARISUTEIAA SUKOTSUTO
IPC: B67D1/00
Filed: 1988-09-29
Abstract: PURPOSE: To seal the fluid tightly by providing an outlet from the pressure vessel, a seal member for closing the outlet, and a pressure release device for transferring the force derived from the pressure in the pressure vessel via the seal member, and bursting when pressure is above a given value to release the pressure through the outlet. CONSTITUTION: A bursting disc 7 is accommodated in an enlarged-diameter portion 8 to contact a shoulder 9. A disc-shaped elastomer seal member 10 made of e.g. rubber is clamped by a clamp plug 5 to contact a shoulder 4 to form a fluid-tight seal. Thus the bursting disc 7 is not necessary to have seal function. The dimensions of the bursting disc 7 and the enlarged-diameter portion 8 of the bore are so selected that when the bursting disc 7 is seated on the shoulder 9, a small gap exists between the surface of the bursting disc 7 and the clamp plug 5. Therefore, the clamp pressure which is possible to degrade the strength of the bursting disc 7 is not applied to the bursting disc 7. The fluid pressure in the pressure vessel presses the seal member 10 to the bursting disc 7.

CONSTITUTION:The contribution of noise power to the 2nd-stage sealing cavity pressure P2 is large when the 2nd-stage sealing cavity pressure P2 increases sharply by certain abnormality. Namely, the ratio at which the component of the sealing water quantity Q occupies is increased and this event indicates that the pressure of the sealing water is transmitted by the wear, damage, etc., of the 2nd-stage seal. The contribution from a pump differential pressure DELTAP is large in the contribution of the noise power on the 2nd-stage sealing cavity pressure P2 when the 1st-stage sealing cavity pressure P1 increases sharply by certain abnormality. Namely, the ratio at which the pump differential pressure DELTAP occupies is increased and this event indicates that the pressure of the pump differential pressure is transmitted by the wear, damage, etc., of the 1st-stage seal. The data on the degree of deterioration are obtd. by preserving these sets of the data in a preservation part 16.
