CONSTITUTION:A jointing device for tube comprises a joint main body 1 which is provided therein with a hole part 2 passing it in its axial direction and in which a flexible tube connecting hole part 9 provided with a step part formed in the middle position of the hole part 2, a locking ring 11 which is formed to wrap and engage with the top end of a flexible tube 10 and engage with the internal surface of the connecting hole part 9, and a tightening member 15 which is screwed into the joint main body 1 and presses the locking ring 11 to the inside of the connecting hole part 9. Also a groove part 5a into which the maximum diameter part of the locking ring 11 is fitted is formed in its axial direction in a female thread part which is extended to the outer end side in conjunction with the connecting hole part 9 and into which the tightening member 15 is screwed. Since the locking ring 11 is engaged with the internal surface of the connecting hole part 9 of the joint main body 1 when the tightening member 15 tightens by rotation, the locking ring makes no rotation following the process of tightening. Thus the flexible tube is prevented from being twisted.

Abstract: PURPOSE:To detect the rotation speed and the rotation angle with a high precision without the influence of the fitting precision, by writing the signal of a fixed frequency onto the magnetic disc, which is rotating in a constant speed, and by reading this signal, in the rotation speed detector. CONSTITUTION:Magnetic disc 3 connected to rotation axis 2 of motor 1 to be measured is rotated in a constant speed accurately by flywheel 5 driven by auxiliary motor 6, and the signal of a fixed frequency is written from oscillator 8 through amplifier 10 and switch 11 by magnetic head 4. Next, wheel 5 is disconnected, and the signal on disc 3 driven by motor 1 is read to obtain the DC voltage corresponding to the speed through amplifier 12 and F-V converter 9, thereby analyzing speed pulsation of motor 1 and correcting the speed detector. Reference position signal S2 is obtained by hole 14 and light receiver and transmitters 10 and 13 to detect the rotation angle.

Title: Motor-driven camera
Inventor: HARAGUCHI SHOSUKE
IPC: G03B17/00
Filed: 1988-02-08
Abstract: PURPOSE:To reduce cost and to employ a small-sized motor by transmitting an output to a preparating mechanism by a motor's rotation in a 1st direction and an output to a film winding/rewinding drive mechanism by the rotation in a 2nd direction and limiting an output to one direction by the rotation in the 2nd direction. CONSTITUTION:Owing to the clockwise operation of a motor M1, a planetary gear 28 is permitted to revolve in the direction in which it meshes with a transmission gear 32, and film is wound. On the other hand, a 1st regulating part 170b inhibits a planetary gear 106 from revolving in the direction in which it meshes with a rewinding gear 110 (the center axis 106a of the planetary gear 106 abuts on the 1st regulating part 170b in the middle of revolution), whereby film rewinding is inhibited. However, the planetary gear 106 is not influenced by the 1st regulating part 170b when the motor M1 rotates counterclockwise; therefore the gear 106 can revolve in the direction in which it meshes with a transmission gear 120, and consequently a mirror is driven and charged. Since one motor can drive three mechanisms in such a way, its cost is reduced, and the title camera can employ a small-sized motor.
