Title: Cutting position deciding method in beveling machine
Inventor: TANAKA TAKESHI
IPC: B23C3/12
Filed: 1993-03-30
Abstract: PURPOSE:To remove the necessity of arrangedly providing the side of a supporting body with a stopper prescribing means composed of a rigid body for reducing the manufacturing cost of a whole device by releasing a clamping means on the side of a supporting body on one side after clamping a work through a supporting body on the other side, and movingly controlling a clamping means on the side of the supporting body on one side in a feed direction or a direction opposite to that. CONSTITUTION:A servomotor 2 is driven in the direction of positive rotation to move a supporting body 1a on one side backward, and when the first detecting switch Sa detects the tip of a flange (a), the servomotor 2 is stopped, and the movement of the supporting body 1a is therefore stopped. Next a clamping means E on one side is actuated to clampedly fix the flange (a) on one side in a work W, and the flange (a) is accurately set up at a cutting position based on a machining means G. Next, a clamping means F on the side of a supporting body on the other side is released, and the servomotor 2 is reversely driven. The work W is thereby advancingly transferred in a clamping state, and during transferring, the tip of a flange (b) on the other side in the work W is detected.

Title: Former for secondarily forming a radial tyre
Inventor: KAWAKAMI MASAAKI
IPC: B29D30/36
Filed: 1981-06-19
Abstract: PURPOSE:To reduce the time required for forming tyres by means of using selectively the device which slides left and right flanges symmetrically at low speed in the tyre-forming period, and the other device which slides either one of the left and right flanges at high speed except the tyre-forming period. CONSTITUTION:When pressurized air is injected into the gap between the end plate 25 of a fluid cylinder 24 and a piston ring 23 through an air path 3a, a right flange 2 is rapidly separated from left flange 1 and slides to the right direction. The right flange 2 stops at a point just before it comes in contact with a right heat portion Gb of a tyre carcass Ga. Next, when the tyre is formed, a screw shaft 9 is regularly rotated, thereby expanding the distance between the right flange 2 and the left flange 1 symmetrically against the center line H at low speed. When pressurized air is injected into a flange cavity 31 through an air pipe 18, the screw shaft 9 is reversely rotated, thereby causing the left and right flanges to approach to a predetermined distance at low speed. The tyre carcass Ga is deformed in a toroidal shape and the green tyre can be formed with the belt, etc. to be adhered thereto.

Filed: 1997-04-14
Abstract: PROBLEM TO BE SOLVED: To obviate the occurrence of a key pad of a non-working state during playing by adopting the constitution to forcibly part a normally open key pad from the seat part of a tone hole via an arm when the control lever of the normally open key pad is pressed. SOLUTION: When the control lever of the normally open key pad is pressed, the normally open key pad is forcibly parted from the seat part of the tone hole via the arm. If, for example, the control lever L1 for G# is pushed down by the fingertip from the state of producing, for example, a G tone, a projecting lever 25 moves upward and the one 24a of the arm 24 is moved upward around a fulcrum S by the upward movement of the projecting lever 25. The other 24b of the arm 24 is, however, placed on the working lever M4 existing in an upper position and, therefore, the arm 24 turns around the contact part T of the other 24b of the arm 24 and the working lever M4 an parts the G# key pad accompanied by a strut 23 from the seat part Oa of the tone hole O, thereby opening the torn hole.

Title: Picture information recorder
Inventor: MURAKAMI HIROYASU
IPC: H04N1/32
Filed: 1983-05-31
Abstract: PURPOSE:To correct phase shift even with a different reproducing signal period by recording a special code added to a prescribed position of a modulation signal of picture information and being a different modulation signal from the former modulating signal onto an information recording medium. CONSTITUTION:A binary-coded picture signal is applied to a shift register 77 and also to a demodulating circuit 79. The shift register 77 stores the binary-coded signal and this storage content is applied to a missing clock detecting circuit 78, where a modulating system different from the modulating system for the picture information is detected. The result of detection is applied to a line synchronizing code detecting circuit 80. When a signal applied from the demodulating circuit 79 is a line synchronizing code (special code) and also a detecting signal is applied from the missing clock detecting circuit 78, the line synchronizing code detecting circuit 38 judges it as a line synchronizing code and outputs the code to a detecting signal control circuit.

Title: Method for preventing corrosion
Inventor: HIROZAWA KAZUO
IPC: C07C67/00
Filed: 1987-04-21
Abstract: PURPOSE:To prevent the corrosion of a metal at a low cost when HF is allowed to react with an org. compd. in the presence of antimony pentahalide, by properly controlling the ratio of the total amt. of water in he HF and the org. compd. to the amt. of the HF fed. CONSTITUTION:HF and an org. compd. are fed into a reactor and allowed to react at about 60-150 deg.C in the presence of antimony pentahalide to produce a fluorinated org. compd. In the reactor, the HF coexisting with the antimony pentahalide exhibits high corrosiveness. When the HF and the org. compd. are fed into the reactor, the amt. of water is restricted so as to satisfy <=4X10<-5> molar ratio of the total amt. (y) of water in the HF and the org. compd. to the amt. (x) of the HF fed (y/x). Thus, the corrosion of a metal coming in contact with the reaction system, e.g., austenitic stainless steel is effectively prevented.

IPC: H04N19/51
Filed: 1992-04-16
Abstract: PURPOSE:To quickly detect a motion vector corresponding to the change of the magnification with a high precision by using plural picture element signals near the minimum value of correlation values to interpolate the motion vector. CONSTITUTION:When a prescribed area is determined in a first field picture by representative point memories 1 and 20, a representative point formed in each block is stored by a correlation detection range setting circuit 31. When a correlation detection range is set in a 2nd filed picture by a parameter setting circuit 10, a parameter T of correlation operation is set. The correlation operation between a prescribed representative point and the picture single of every T-th picture element is performed in accordance with the parameter T, and the minimum value of correlation values is detected by a minimum value detector 6. Plural picture element signals near the minimum value are used to interpolate the motion vector by an interpolating operation device 24, and the interpolated vector is detected. Thus, the motion vector corresponding to the change of the magnification is quickly detected with a high precision.
