Title: Vacuum deposition device
Inventor: TANIMOTO SATOSHI
IPC: C23C14/24
Filed: 1985-04-25
Abstract: PURPOSE:To eliminate the clogging of a mesh and to obtain a uniform film deposited by evaporation in a device for depositing the vapor from a vapor source by evaporation onto a base body for deposition via mesh in a vacuum vessel by making heatable the above-mentioned mesh. CONSTITUTION:The base body 3 is disposed in the vacuum vessel 1 and the vapor source 5 for contg. a base material 4 is disposed below the body 3. The mesh 8 to be heated by a heating means 10 is disposed between the body 3 and the vapor source 5. The vapor is generated when the energy from an electron beam generating source 6 is supplied to the source 5.

Title: Single-lens reflex camera
Inventor: TERADA KATSUMI
IPC: G03B9/02
Filed: 1979-07-11
Abstract: PURPOSE: To perform program system automatic exposure controlling with simple construction by  magnetizing an electromagnet according to the brightness of the subject, and controlling the  extent of operation of an aperture lever by the magnetic force of a permanent magnet opposing  thereto.  
     CONSTITUTION: According to the brightness of the subject, a control circuit controls the electric  current supplying of the electromagnet 17 of an aperture control mechanism. When the subject is  bright, electric current is flowed to the electromagnet 17 which in turn causes a suction piece 21 to  be sucked to the electromagnet 17 and a suction piece 23 to be repulsed. A detaining lever 16 is  turned around a stationary pin 24. Consequently, when an aperture ring 13 is turned, the end of  the detaining lever 16 contactually touches the step part on the inner side of a staircase part 13  and does not open the aperture too much because of the small extent of movement of the aperture  ring 13. When the subject is of ordinary brightness, no electric current is supplied to the electromagnet 17. The detaining lever 16 is then maintained in an equilibrium state and the extent of the  movement of the aperture ring 13 becomes of a medium degree. When it is dark, electric current  is supplied in the reverse direction and the aperture ring 13 moves in a large extent, thereby opening the aperture fully. Thus, the exposure may be automatically controlled with the simple construction.

Title: Tension controller for cold rolling mill
Inventor: MORI MASATSUGU
IPC: B21B37/54
Filed: 1997-04-07
Abstract: PROBLEM TO BE SOLVED: To correct a tension disturbance received at the time of a rolling start and at the time of acceleration and the deceleration of a line by interfacing the estimated value of a motor field from the motor variable speed controller of unwinder and take-up machine, providing a field correcting circuit correcting a field shift occurring in terms of a vector control, and inputting a corrected value obtained by the field collecting circuit to a motor torque current output calculating circuit. SOLUTION: A motor field estimated value 16 required in terms of the vector control is interfaced from the motor variable speed controller. By using the value, the field shift is corrected by adding a field correcting circuit 17, and the precision of the motor torque current output calculating circuit 11 is enhanced. That is, the motor field is changed by the number of rotations of a motor, and its change is changed further by the acceleration and the deceleration ratio of the motor. Also, a deviation occurs in between the estimated value of the field and an actual motor field by the design error of a motor secondary time constant and the field shaft. Therefore, the field correcting circuit 17 is provided so that this deviation is eliminated.

Title: Contact lens for laser operation
Inventor: EMU BURUUSU SHIIRUZU
IPC: A61B19/00
Filed: 1990-04-02
Abstract: PURPOSE: To make it possible to reduce burning that may be caused outside eyes by making a surface dent inward recessed from the light-emitting surface, which is formed to have a slightly larger radius of curvature than that of average human cornea, and by protecting out this dent, as a spacing from the cornea epithelium is kept remained at a state of making a jet-out surface contact with the sclera. CONSTITUTION: The incident surface 12 of lens is flat, and has a relation of right-angle to the optical axis of the lens that agrees with the optical axis of eyes. The light- emitting surface 26 gets a contact with the sclera 27 connected adjacently to the cornea 42 and surrounding it. A dent 28 with a slightly larger diameter than that of the cornea 42 protects the cornea 42, as a spacing from the cornea 42 is kept remained in such a state that it does not touch the cornea epithelium. An opaque button 32 at the lens center prevents the light from entering into eyes 25 along the optical axis throughout a fairly-long distance at both sides of the optical axis. Neither the scattering light nor laser light from the light source of a microscope can, therefore, enter into the optical part of the eyes. Since this reduces the hyperemia of conjunctive, absorption of the laser energy at this level is suppressed as much as possibly to reduce a frequency of burning the conjunctiva.
