It is made much smaller than the diameter of the bottom part 11e of the straight advance groove 11a of a fixed barrel 1 forming a cam mechanism being the extending mechanism is made much smaller than and formed large enough to be engaged with the follower. Namely, the holding part 33 is overlapped on a part of the follower in the length in the direction perpendicular to the optical axis, and the barrel 6 can not move in the optical axis direction.  Thus, coupling is prevented from being released by a locking part 32 at the time of bending even in the case external force is exerted on the barrel 6 and the barrel 1 or a rotary barrel 2 is bent.

Title: Magnetic-head actuator
Inventor: HASEGAWA KATSUHIDE
IPC: G11B5/588
Filed: 1992-01-28
Abstract: PURPOSE:To reduce the bad influence of a centrifugal force due to the rotation of a magnetic head when a magnetic-head actuator is built in a rotary magnetic-head device and to stably actuate the actuator by a method wherein the movable part of the magnetichead actuator is supported by using four plate springs which have been arranged and installed nearly symmetrically around the center of gravity of the magnetic-head actuator. CONSTITUTION:Permanent magnets 1a, 1b are fixed and bonded in such a way that N-poles are faced with each other and that an inner yoke 2 is sandwiches between them. Magnetic fluxes from the N-poles of both magnets 1a, 1b are returned, from the inner yoke 2, to S-poles through outer yokes 3b, 3a, 3c via an air-gap part on which a coil 14 is arranged and installed. Consequently, a radial magnetic field toward the inner yoke 2 and the outer yoke 3b is formed. Plate springs 5, 6 which support a bobbin 4 are fixed and bonded to outer circumferential parts 4a, 4b at the upper part and the lower part of the bobbin 4. Thereby, when an electric current is made to flow to the coil 14, an electromagnetic force is generated between the inner yoke 2 and the outer yoke 3b. The bobbin 4 is displaced along an axis 11 until the electromagnetic force and the repulsive force of the plate springs 5, 6 are balanced.

Title: Single shaft planetary rolling mill
Inventor: NAKANO JUNSUKE
IPC: B21B13/20
Filed: 1986-01-24
Abstract: PURPOSE:To simplify the construction and to prevent the fluctuation of a sheet thickness and the formation of wave patterns by forming the inside surface shape in the final rolling part of a stationary late to an arc concentrical with the rotating circumcircle of a work roll and making the space between the arc and the circumcircle equal to a desired sheet thickness. CONSTITUTION:The inside surface 41 of the stationary disk 4 in contact with a rolling material 5 is divided to 4 sections. Rolling is not executed in the section A-B where the rolls function as a guide for the material 5. The thickness of the material 5 decreases considerably and the shape of the inside surface 41 of the stationary disk in the section B-C decreases in the sheet thickness as the material progresses. The section C-D is the arc of a radius R2 concentrical with the rotating circumcircle 23 of the work roll 2 and R2-R1 is made to coincide with the desired sheet thickness so that the length of the arc C-D is made larger than the length of the material 5 on the outlet side. The space between the circumcircle 23 and the inside surface 41 of the plate 4 is constant in the section C-D and therefore, the thickness is adjusted to the specified thickness by light draft rolling in the rolling in the section B-C. The rolls in the final section D-E act as a mere guide for the material 5.

It is exposed to a light image of an original  10 to erase the charge of the toner corresponding to the light part of the original 10 (part  except the hatched part), or the polarity of the toner 9 on the light part is reversed by applying bias voltage reverse in polarity to the toner 9 to the film 4 from a DC power supply 11.  Then, a transfer material (paper or the like) 12 is placed on the toner 9, charge reverse in  polarity to the toner 9 to be transferred is applied to the back side of the material 12 with a  charger 14 to transfer a toner image and fix it, thus permitting a sharp image free from  defects, such as background stains or lack of density to be formed with high sensitivity.

Title: Transistor circuit
Inventor: ABE KOUJI
IPC: H03G3/10
Filed: 1984-01-27
Abstract: PURPOSE:To attain the satisfactory comparison for lower power supply voltage by inserting a DC level shift circuit between the base of an amplifying transistor of the first stage and an input terminal. CONSTITUTION:The collector current of a transistor (TR)42 is foled by a current mirror circuit CM4 and compared with the collector current of a Tr41. This differential current is used as the base current of an output Tr46, and the output of a voltage comparator is obtained from the collector of the Tr46 through a terminal 10. In such a way, the collector currents of both Trs 36 and 38 are supplied as the reference current to give the DC level shifts to input terminals 1 and 2. Thus it is enough to supply the power supply voltage larger than the sum of the base-emitter voltage VBE of npn type Trs 41 and 42 of a differential amplifier DA4 and the saturated collector-emitter voltage of pnp type Trs 44 and 45 of the circuit CM4. Therefore the comparison is possible for lowe power supply voltage of 1V with supply of DC voltage less than the voltage VBE.
