Title: Synchronizing mechanism
Inventor: INUI MASAKI
IPC: F16H3/12
Filed: 1987-05-22
Abstract: PURPOSE:To prevent the axial regulating force of a synchronizing ring from affecting upon the tolerance or the like of assembly of a synchronizing device by using a plurality of key members and springs for coupling between a gear spline section and the synchronizing ring. CONSTITUTION:A key body 14a has such a width that it is circumferentially positioned and secured when it is fitted in a second groove part in a gear spline section 16. Due to the provision of a spring 15 which abuts against a stepped part between the key body 14a and a leg part 14e, a shifting key 14 is supported movably in radially inward and outward directions. Accordingly, when axial action is exerted to a synchronizing ring 13 overcoming a regulating force, the spring 16 is deflected in the radially inward direction while it is moved through between both bank parts 14b of the shifting key 14, thereby it is possible to prevent the above-mentioned regulating force from affecting the tolerance of assembly of the synchronizing device.

Title: Time axis compensator for reproducing signal
Inventor: OKANO TAKASHI
IPC: H04N9/89
Filed: 1981-08-13
Abstract: PURPOSE:To provide broadband characteristics with a simple constitution and to improve the characteristics with less spurious radiation, by controlling the impedance of a variable impedance element in accordance with the fluctuation of time axis of a reproducing signal. CONSTITUTION:A reproducing signal with time axis fluctuation goes via a resistor R6, and an emitter output of a transistor (TR)Q1 is inputted to a base of a TRQ4 and the phase amplitude characteristics of the emitter output are controlled with a variable impedance of a diode D. The output is inputted to the base of a TRQ3 via a resistor R7 and summed and mixed with the emitter output of a TRQ2. In selecting the resistors R6 and R7 equally, the amplitude  transfer characteristics are constant independently of the impedance of the element D. The phase transfer characteristics are changed depending on the impedance of the element D. Since the capacitance value of the diode D is changed  in accordance with the time axis error of the reproducing signal, the phase of  a reproduced color signal can be controlled.

Abstract: PURPOSE: To hold the resistance and reliability of materials assembled without risk of damaging the materials around a hole by including a tubular washer which has an insertion part and a tail part, a head with a diameter equal to the outside diameter of the insertion part, and a shank placed within the bore of the washer. CONSTITUTION: The extension 2c of a shank 2 is gripped by the jaw of a tool and drive T is imparted to the trunk of the shank 2 while a counter pressure P is imparted to a head 3 preformed by an anvil. The free end of a washer held abutting against the head of the shank by holding devices 6-8 is subjected to a longitudinal force, this force being converted into moments in the portions of two articulation zones 5c, 5a for the structural disposition of a tail portion, thus causing the folding action of the zones. The folding action causes the action of an inclined portion 5b to fold back and urges the inclined portion 5b to abut against materials. A support surface thus formed guarantees that the materials are held while having resistance and reliability without causing damage of the materials at the edge of a hole.

Similarly, the discrimination part 62 discriminates whether the signal M is present at the point of time which is the specific time after the signal L or not. The voltage setting part 7 varies set values on the basis of the outputs of the discrimination parts 61 and 62 and new voltage set values are supplied to the detection parts 51, 52, and 53 through a generating circuit 8. Further, a measurement of time is taken on the basis of the signal M obtained through the detection part 52.
