Title: Lens barrel
Inventor: TAKEZAWA KAZUMITSU
IPC: G02B7/10
Filed: 1987-02-20
Abstract: PURPOSE:To prevent a manual focusing operation ring from touching a hand which holds a lens barrel and to eliminate hindrance to automatic focusing operation by inhibiting the manual focusing operation ring from rotating together with a focusing operation ring in automatic focusing mode. CONSTITUTION:When a changeover switch 7 is set in the automatic focusing mode, the tip part 9a of a leaf spring 9 exits from a groove 4a, so the manual focusing operation ring 6 and focusing operation ring 4 are disengaged from each other and the manual focusing operation ring 6 becomes free. Namely, only the focusing operation ring 4 rotates by receiving the driving force of a motor. Consequently, a focusing lens group 1 moves in the direction of the optical axis to perform the focusing operation. Consequently, the manual focusing operation ring 6 does not contribute to the focusing operation at all in the automatic focusing mode, so even if the ring is touched by the hand, there is no influence exerted on the focusing operation.

Title: Method and apparatus for absorbing and releasing hydrogen
Inventor: AKIMOTO MASAMICHI
IPC: H01M4/24
Filed: 1986-02-20
Abstract: PURPOSE:To easily and efficiently absorb hydrogen into an oxy acid soln. in such a manner that the hydrogen can be released by isolating the oxy acid soln. which can be reduced and hydrogen-contg. gas with a gas-liquid separating membrane which can allow permeation of proton and dissociating the hydrogen to proton. CONSTITUTION:A switch SW is connected to ab and the hydrogen-contg. gas is introduced from a gas introducing hole 3 into the 2nd vessel 4, where the gaseous hydrogen is dissociated to the proton in an electrode 6a part on the gas-liquid permeable membrane 5 which allows the permeation of the proton. The proton is introduced through the membrane 5 into the 1st vessel 2. On the other hand, the released electrons reduce the oxy acid in the oxy acid soln. 7 of the 1st vessel 2 and form the complex of the oxy acid and proton. The hydrogen in the gas introduced into the 2nd vessel 4 is thus absorbed into the soln. 7. When the switch SW is connected to ac, the complex in the soln. 7 oxidizes to dissociate the proton. The proton passes the members 5 and is released in the form of the gaseous hydrogen in the electrode 6a part. The absorption and release of the hydrogen are thus efficiently executed by the simple operation.

Title: Evaluation method and device for film thickness uniformity and automatic control method and device for film thickness
Inventor: YAMADA YOSUKE
IPC: B65H26/02
Filed: 1988-02-20
Abstract: PURPOSE:To enable the evaluation of film thickness uniformity by projecting light for plural positions in the widthwise direction of a film roll, measuring the quantity of light reflected from the film roll and evaluating a difference in the quantity of light reflected from the plural positions. CONSTITUTION:A film roll 22 upon completion of a winding process, is shifted to a position adjacent to a thickness uniformity detecting device 24, a pneumatic cylinder 34 operates to make a support member 32 come near the film roll 22 and this support member 32 stops moving at the position where a stopper 40 comes in contact with the film roll 22. In this state, a plurality of photoelectric sensors 38 operate to project the predetermined light to the film roll 22 and receive light reflected therefrom. When the thickness of a film taken up with the aforesaid roll 22 is not uniform in a widthwise direction, air is entrapped in the portion of small thickness, thereby generating an emulsive and opaque condition. The quantity of reflected light at the aforesaid portion, therefore, increases and the sensor 38 is turned on, thereby enabling the sensing of a thin film portion. Also, the signal of the sensor 38 is inputted to a controller and the uniformity of film thickness is thereby evaluated.

Title: Chain conveyor for carrying cylindrical container
Inventor: MORI KINTAROU
IPC: B65G23/38
Filed: 1979-03-28
Abstract: PURPOSE: To enable manual carrying of chain, by providing a projection and a cylindrical rear contact section on a carrier cam while providng a cam opening prevention lever having a hole to be engaged with the projection upon rotation of the feed cam.  
     CONSTITUTION: When pushing a chain 3 to the arrow direction, a cylindrical section 3A moves to press a cylindrical rear contact section 26, thereby a feed cam 10 moves clockwise and a projection 25 engages with an engaging hole 24 to disable the movement of chain 3. When the chain isn't pushed to the feeding direction, the feed cam 10 is pressed counter-clockwise by the tension of a spring 11 thereby the projection 25 is disengaged from the engaging hole 24. Consequently when the cylinder is driving, the chain 3 can be moved through a feed cam 10. While when moving a cam opening prevention lever 17 to the direction A, the projection 25 doesn't engage with the engaging hole 24 even if the feed cam 10 is turned thereby the chain 3 can be advanced manually.

Filed: 1990-02-16
Abstract: PURPOSE:To measure a flow rate up to a logical lower measurement limit and to expand a flow rate measurement range by forming at least one set of mutually opposite slots at right angles to the flow direction of fluid. CONSTITUTION:The fluid 100 which flows in a flow passage flows in the jet nozzle 40 of a fluid oscillator 30 and is jetted as a jet flow 200 to a target 42. At this time, vortex flows are formed in the slots 46a and 46a with the jet flow 200 in the nozzle 40. The size of the generated vortex flows is prescribed by the size of the slots and the flow velocity of the part of the jet flow 200 contacting vortex rings is equalized to the flow velocity of the vortex rings. Namely, the slots 46a and 46a are provided to prescribe the flow velocities of the parts of the jet flow 200, which contact the slots 46a and 46b, with the vortex. Thus, the border layer of the jet flow 200 in the nozzle 200 is prevented from being developed and the flow velocity of the vortex peripheries affect the flow velocity distribution nearby the wall surface of the nozzle.

Title: Blade and its manufacture
Inventor: YANAI NORIYUKI
IPC: C08G18/10
Filed: 1988-02-19
Abstract: PURPOSE:To improve durability, lubricity, and cleaning performance by incorporating a low-surface-energy compound in a polymeric elastic body as primary particles of <=1mum in mean particle size or in a compatible state. CONSTITUTION:The low-surface-energy compound is incorporated in the blade as primary particles of <=1mum in mean particle size, preferably, in the compatible state. In this state, the low-surface-energy compound reacts completely on a polymeric elastic body forming material. Namely, the low-surface-energy is present in the polymeric elastic body not in large irregular particles, but in the uniform state while reacting with the polymeric elastic body forming material. Therefore, when residual toner on a photosensitive body is cleaned, particle components of the low-surface-energy compound as an irregular part of the blade are prevented from falling owing to the rubbing between the blade and the surface of the photosensitive body and the edge part wears uniformly at all time. Consequently, cleaning removal ability is improved greatly and invariably excellent cleaning effect is obtained.

Abstract: PURPOSE:To decrease the number of times of switching of a switching means and the generation of heat and electromagnetic noise by synchronizing the rise of a PWM(pulse width modulation) signal with that of ON control signal and by setting the period of said PWM signal as the minimum ON period more than 1. CONSTITUTION:Outputs UL, VL, WL of a coil-ON logical circuit 2 is supplied to a rising pulse generator 11 to generate an output pulse synchronized with the rise of said outputs UL, VL, WL. The output pulse from said rising pulse generator 11A is supplied as reset pulse to a PWM signal generator 10. In this case, a rising pulse is outputted for every period twice as long as the minimum ON period by the output of said coil-ON logical circuit 2 and at every 120 of an electrical angle, and said PWM signal has a period twice as long as the minimum ON period by the output of said coil-ON logical circuit 2. Thus, even if switching characteristics of diodes D1-D3, D11-D13 are poor, it is possible to reduce the number of times of switching, a heat generation because of no through current flowing, and also the generation of electromagnetic noise.
