IPC: B21C37/20
Filed: 1980-06-18
Abstract: PURPOSE: To easily form longitudinal grooves in the desired positions of a metallic pipe by pressing dies onto the metallic pipe by means of pressing means, and forming grooves in axial direction between the dies and a mandrel.  
     CONSTITUTION: Split dies 4 are opened outward by moving wedges 7 rightward by means of hydraulic cylinders or the like, and a pipe 1 is inserted into the dies 4. At this time, a mandrel 2 fixed at one end is inserted into the pipe 1, and is so adjusted that its creset parts 2a oppose diametrically to the grooves of the dies 4. The wedges 7 are then pushed in leftward to approach the dies 4 slightly inward in a diametral direction, thereafter, a driving ring 10 is rotated. If the abutment points of the rollers 6 with backers 5 are moved from the position of 5a to 5c and further from the position of 5c to 5b, the leading end parts of the dies 4 give impact to the pipe 1, thereby pressing the pipe 1 to the mandrel 2. Since the four dies 4 press the pipe 1 simultaneously at this time, the pipe 1 is formed with longitudinal grooves over the entire circumference thereof.

Title: Production of ring gear by precise press forging
Inventor: OGAWA SUEAKI
IPC: B21K1/30
Filed: 1995-04-07
Abstract: PURPOSE: To simply produce a ring gear having thick thickness in a low cost and high precision with a press by correcting the rollover of a shoulder part and the gradient of a shear cross section developed in a previous process and simultaneously shrinking the outer diameter so as to become a desired finish outer diameter of the ring gear. CONSTITUTION: In a preform 24 formed through a first process and a second process, the rollover 25 is developed at the corner part of peripheral edge on the side surface of a female die 2, and in a shearing cross sectional surface, the preform is formed as the developing state of the gradient 27 in the shearing cross sectional surface. Further, this preform 24 is laid by turning over to the female die 2 of a side set part 1 and a punch 4 is made to descend. Then, since the inner diameter of the female die 2 is formed to the small diameter so as to become the finish outer diameter of the ring gear, at the time of drawing the preform 24 with this female die 2, the drawn excess thickness, etc., is flowed into the rollover 35 part and the gradient 27 part of the shearing part developed in the first process and the second process.  Thus, the precise ring gear having the prescribed size by correcting in the condition of scarcely developing the shoulder rollover 25, surface rollover and gradient 27, is formed.

Title: Illuminator
Inventor: YONEZAWA YASUO
IPC: G02B21/06
Filed: 1995-03-15
Abstract: PURPOSE: To optically improve the contrast of an image even with respect to a sample having low contrast by providing a light splitting means and a projection illuminating optical system. CONSTITUTION: The rest part of transmitted light from the sample 6 on which the unmagnified images of the sample 6 are projected and illuminated in a state where they are superimposed is removed outside the optical path of an observation optical system again through a half mirror 8. The light taken out from the optical path forms the intermediate image of the sample 6 through a first relay optical system constituted of an image-formation lens 11 and a mirror 12. The light from the intermediate image forms the unmagnified image of the sample itself on the sample 6 through a second relay optical system constituted of a mirror 14, a relay lens 15, a half mirror 3 and a condenser lens 5. The feed-back illumination is succeedingly repeated. Thus, the bright part of the sample 6 is brighter illuminated, and the dark part is more darkly illuminated.  As a result, the contrast of the sample image formed on an image surface 10 can be improved even though the contrast of the sample 6 is low.

Title: Fail-safe logic circuit
Inventor: YODA MITSURU
IPC: H03K19/007
Filed: 1978-07-08
Abstract: PURPOSE:To remove operation unstableness at the time of actuation by securing fail and safe completeness by connecting a logic converter circuit, which generates a constant level output by being supplied with a negative polarity voltage or positive polarity voltage excluded from an input, in series to a feedback circuit. CONSTITUTION:NOT circuit T is inserted into the feedback circuit and feeds NOT AS or OS of output AS or CS of basic logic circuits OR back to the input of basic logic circuit A1. Here, inputting a negative-polarity or positive-polarity voltage excluded from an input generates a constant-level output and NOT output -V equivalent to ''0'' is outputted corresponding to the input condition of circuit A1. With an input of direct current voltage -V equivalent to ''0'', oscillations start at a fixed threshold level and NOT output +V is developed. Consequently, the unstableness of starting operation can be removed with assurance of perfect fail and safe.
