Inventor: YOKOTA HIDEO
IPC: G02B7/32
Filed: 1984-10-05
Abstract: PURPOSE:To attain highly accurate automatic focus detection by reflecting radiated infrared light flux by the reflecting surface of an optical compensating means, projecting the reflected light to the object side through a reflector and a photographing system, and then detecting the reflected light flux from the object side by a photodetecting means arranged near the photographing system. CONSTITUTION:Light flux passed through the photographing lens 1, reflected by a movable mirror 2 and obtained from the objected side is passed through the optical compensating means 9 for setting the aberration of the input to a value approximately equal to that of a spherical surface of the photographing system which may be generated due to the arrangement of a low-pass filter or the like and then formed on a focal plate 10 arranged on a position optically approximately equal to that of an image pickup surface 7. The object image is turned to an erected positive image by the 1st and 2nd prisms 11, 12 and observed on the position of an observing pupil E by an eyepiece 13. The automatic focus mechanism reflects infrared light flux radiated from a light source 14 on the reflecting surface of the means 9 and the movable mirror 2 and then projects the reflected light to the object side through the lens system 1. Thus, the simple automatic focus means is constituted by utilizing the thickness of the means 9 effectively.

Abstract: PURPOSE:To improve sharpness of injection thus to improve combustion by producing end-of-injection high hydraulic pressure through sub-plunger provided on the upper section of single plunger then applying said hydraulic pressure onto the back face of needle valve thereby increasing the valve-close pressure. CONSTITUTION:Upon lifting of plunger 1' to cover the oil supply/discharge hole 201 by means of a reed 101, fuel is pressurized to open the delivery valve 4 to feed fuel through injection tube 6 and oil path 9 into oil sump 801 and upon reaching of hydraulic pressure to the valve-open pressure of needle valve 10, injection will start. Upon further lifting of plunger 1', the reed 102 will open said hole 201 while at the same time, sub-plunger 103 will penetrate through a barrel 301. Consequently, fuel in barrel 301 is compressed to transmit the pressure through an oil path 105 to an annular groove 104. Since said groove 104 will meet with annular groove 202, hydraulic pressure is further fed through oil paths 203, 302, 502, hydraulic tube 601 and oil path 17 to the hydraulic chamber 16 on the rear face of needle valve 10. Consequently, the needle valve 10 is closed forcefully to complet injection.

Filed: 1986-09-05
Abstract: PURPOSE:To reduce the dispersion of a coil by providing coil grooves on the inner peripheral section of a horn-shaped reel, providing slants on bottom sections of the coil grooves, and alignment-winding the coil for each winding from the low section toward the high section. CONSTITUTION:Bottom sections of coil grooves 2 on the inner peripheral section side of a horn-shaped reel 1 are inclined, a coil lead wire 3 is alignment-wound for each winding from the low section side toward the high section in the coil grooves 2.

IPC: A47K5/12
Filed: 1989-08-16
Abstract: PURPOSE: To prevent fluid from leaking out and dropping down, to enable to positively distribute a measured volume of fluid, by pushing up a plunger to push up a spring means to push out the fluid from the plunger, and moving the plunger downward by the spring means to suck the fluid from a container to the inner part of a cylinder. CONSTITUTION: Fluid is distributed by upward pushing a plunger 32. A dispenser acts as a positive distribution pump. A chamber in a valve cylinder between valves 33, 35 is usually empty, once or twice of priming water strokes are required at the beginning. The fluid is pushed into the chamber to forcibly open a valve and the fluid is pushed out from the chamber to a flow path of the plunger and discharged through an exit opening 47. When a hand is removed form the inner part of the chamber between valves 33, 35 becomes vacuous. As a result, when the fluid flows in the lower direction from the container through the valve 33 by a positive pressure on the valve 33, a flapper 56 is separated from a shoulder part 54 and the chamber is filled with a predetermined volume of the fluid.

Title: Rotary angle pulse generating circuit of rotary body
Inventor: FUJII MASAHIKO
IPC: G01P3/481
Filed: 1981-12-30
Abstract: PURPOSE:To generate the rotary angle pulse having a unit angle smaller than equally spaced angle of rotary angle reference bodies, by detecting the passage of the rotary angle reference bodies equally spaced around the outer surface of the rotary body, counting the number of high speed clock pulses at every period of the generated sensor signal, and generating the rotary angle pulse every time the high speed clock pulses are counted by the number which agrees with the value that is 1/N the counted value. CONSTITUTION:When the rotary body 1 is rotated in association with the rotation of a body whose rotation is to be detected, a sensor 3 detects the passage of tooth parts 2 and generates the output. A counter 7 counts the number of the clock pulse in every period of the sensor signal A and outputs the result. A latch circuit 8 divides the counted value Y of the pulse phi by using an expression 1/2n=1/N and accepts the result. A down counter 9 performs the down cout every time the pulse phi is supplied. When the counted value reaches a preset value, the rotary angle pulse D is generated from an output terminal OUT. The rotary angle pulse D whose frequency is multiplied by N=2n times, is outputted. Therefore the unit angle is made smaller to 1/N=1/2n in comparison with the conventional angle.

Filed: 1985-09-24
Abstract: PURPOSE:To make easy the processing of non-circularity part for ensuring coupling with synthetic resin and ensure working efficiency by making a tool get in contact with the external surface of a workpiece while eccentrically turning the center of a rotary axis, and forming a crescent form recess through cutting a part of the entire periphery. CONSTITUTION:An independent chuck mechanism causes the deep movement of only a claw 11a and the shallow movement of other two claws 11b and 11c, as claws 11a, 11b and 11c supported on a body 10 are able to work independently of each other. As a result, the center C1 of a rotary axis 1 chucked with three claws 11a, 11b and 11c comes to be out of alignment with the center C2 of the chuck body 10. The turning of the chuck device causes the eccentric turn of the rotary axis 1 and makes it possible to form a recess 6 of a crescent. When the external surface of a workpiece is machined as aforementioned, it is possible to carry out a secondary process simply through the eccentric mounting of the axis 1 after a primary process by repeating similar work.

On the other hand, the output of a F/V converter 12 and the phase comparing signal are inputted into an error amplifier 14 while the output of the error amplifier 14 is compared in a comparator 15 with the output of a triangular wave oscillator 16. The output of the comparator 15 is applied on the base of a switching transistor 9 through a pulse transistor 10. According to this method, the improvement of reliability and the reduction of cost may be contrived.
