Title: Automatic gain adjusting circuit
Inventor: MINAMI YOSHIHISA
IPC: H04N5/53
Filed: 1989-04-24
Abstract: PURPOSE:To attain stable gain control against noise by providing an automatic frequency control oscillation circuit. CONSTITUTION:When a video signal (a) is inputted from a terminal 1 to a synchronizing separator circuit 2, a horizontal synchronizing signal (b) is outputted while being separated from the signal (a). The signal (b) is inputted to a phase comparator circuit 22 of an automatic frequency controlled oscillation circuit 24, the circuit 22 compares the phase of the signal (b) with a charge/ discharge voltage signal c' inputted separately and outputs a phase comparison output signal (p) to an LPF 23. The LPF 23 integrates the signal (p) to output a signal (q) controlling the oscillating phase to a horizontal oscillation circuit 21, in which the charge/discharge of a charge/discharge capacitor 4 is controlled so that the phases of the signals b, c' are coincident. Since the signal (p) is integrated by the LPF 23 and the resulting signal is inputted to the circuit 21 even when noise is superimposed on the signal (a), the oscillating phase of the circuit 21 is made constant and the stable signal c' is obtained. Thus, a gain control circuit 3 applies stable gain control.

Title: Clutch drum
Inventor: FUJIOKA KAZUYOSHI
IPC: F16D13/60
Filed: 1982-06-21
Abstract: PURPOSE:To increase the strength of a clutch drum by a method wherein one wall of a snap ring groove provided in the ridge part of the outer periphery of the clutch drum is buckled without breaking a base metal while the other wall is formed by half cutting of the base metal breaking it partially. CONSTITUTION:A clutch drum 21 is provided with a groove 23 formed in a part of the ridge part thereof for fitting a snap ring 24 thereto. One wall 23a of the groove 23 is buckled in the continuous state without breaking the base metal of the clutch drum 21, while the other wall 23b is formed by half cutting whereby the base metal of the clutch drum 21 is broken partially. According to this method, it is unnecessary to break completely the ridge part 22 so as to form the groove 23, while an extruded part 23c, which forms the bottom of the groove 23, acts as a rib so as to improve the rigidity, and thus the strength of the clutch drum 21 can be improved to a great extent.

IPC: B60R25/02
Filed: 1978-08-31
Abstract: PURPOSE: To prevent steering shafts from engaging at random due to incorrect key removal during running by mounting a means to hold the release state of the steering shafts during operation.  
     CONSTITUTION: In the locked steering shaft A whose key is removed, since the hanger 3 and the locking rod 5 are pushed by way of the coil spring 12, it is locked up by the locking rod 5. In the operated steering shaft A whose key is inserted, the hanger 3 and the rod 5 are pulled up by the actuation of the cam 8, it is unlocked. On the other hand, the revolving locking plate 9 starts its revolution by detecting the moving state of wheels as soon as they are ready to move and is pushed in the groove 8a. This permits the release state of the steering shaft to be held during operation.

Title: Autoantibody detecting method by indirect antigen immobilization
Inventor: IGARASHI KOJI
IPC: G01N33/564
Filed: 1998-04-17
Abstract: PROBLEM TO BE SOLVED: To reduce the using quantity of antigen through the use of an antigen coupled with a water-insoluble carrier via an antibody. SOLUTION: An antigen coupled with a water-insoluble carrier through an antibody is used. As the water-insoluble carrier, a one providing a surface for directly or indirectly combining the antibody of various carriers used in immunoassay is used. The size of the water-insoluble carrier is not limited, and particle sizes of, for example, several 100 μm to about 1 cm can be selected arbitrarily. Thus, since the antigen is coupled with the water-insoluble carrier through the antibody, the antigen can be submitted for the immunological reaction with the antibody to be detected in a state in which the directivity of the antigen is controlled.  Consequently, since the epitope of the antigen will not be coupled in a state which in capable of participating in the immunological reaction, the antigen quantity used for the combination matches with the actual antigen quantity participating in the immunological reaction with the antibody, and the use of a large quantity of antigen is not required.

Abstract: PURPOSE:To allow stable slitting by slitting a film after expanding it in the axial direction with an expansion roller. CONSTITUTION:An original film 2 released from a wide original roll 1 is guided to an expansion roller 7 and is expanded in the width direction to remove wrinkles or shrinkage. A nip roller 8 is provided directly behind the expansion roller 7 to pinch the original film directly after it is expanded, the film from which wrinkles or shrinkage are removed is once fixed in this condition, then it is shifted to a slitting unit 9. Narrow films thus slit are individually tension- controlled by winding devices 10 and wound into film rolls. Accordingly, tension mottles in the width direction are eliminated, thus allowing stable slitting of the film.
