IPC: F16C11/06
Filed: 1982-09-28
Abstract: PURPOSE:To provide predetermined retaining force in the ball joint even if the metal ring is fabricated with some tolerances, by allowing the extension of the cap to push down the metal ring along the tapered surface of the ball receiving portion, so that the diameter of the metal ring is reduced. CONSTITUTION:The ball 2 is put into the ball receiving portion 4 of the socket 3 made of plastic and the metal ring 12 is slipped on the ball 2 from above to pass its equator line 2'. Then, the cap 5 made of plastic is screwed into the ball receiving portion 4, whereby the metal ring 12 is pushed down by the bottom face of the cap 5 and, as the metal ring 12 moves downward along the tapered surface 7 of the ball receiving portion 4, cuts therein are narrowed to make its inside diameter smaller than the equator and it is also pressed against the lower end of the tapered surface 7. The retaining force for preventing the ball stud 1 from slipping off the socket 3 is thus provided at desired strength according to the resilience of the ring 12 and the pressure exerted by the cap 5.

Filed: 1988-07-06
Abstract: PURPOSE:To enable detection of the intensity of a magnetic field by impressing a signal of resonant frequency on a parallel resonant circuit of a superconductor inductance and a capacitor and by detecting a change in the impedance of the resonant circuit at the time when a magnetic field acts. CONSTITUTION:An inductance 11 formed of a superconductor and a capacitor 12 are connected in parallel to form a parallel resonant circuit, whereon a direct current I is impressed from as oscillator 14 through a resistance 15 and an alternating current i(t) of resonant frequency therefrom through a capacitor 18. When a magnetic field H acts on the inductance 11 in this state, a resistance value of the superconductor in an equivalent circuit of the inductance 11 is varied in accordance with the intensity of the magnetic field H and so the impedance of the parallel resonant circuit is varied. When an output voltage of a coil 13 coupled electromagnetically to the inductance 11 is subjected to a digitizing processing by a circuit 16, according to this constitution, a change in the impedance corresponding to the intensity of the magnetic field H is outputted as a detection signal from an output terminal 17. Therefore the intensity of the magnetic field H can be detected in the form of an amplitude- modulated high-frequency signal.

Filed: 1988-07-06
Abstract: PURPOSE:To save energy and enhance the safety by furnishing a timer which is operated by a warm keeping switch, and by holding the temp. at the set value or an even lower warm keeping temp according to necessity. CONSTITUTION:When power supply 1 is turned on and the temp. is set, the sensing signal from the temp. around a heater 3 given by a temp. sensor 13 is fed into a temp. sensing means 9. This means 9 converts the input into a comparable signal, while a comparison control means 6 compares the result with the set temp. A control signal is given to a heater control circuit 7 so that temp. around the heater 3 is held at the set temp. When a warm keeping switch 11 is pushed, the mean 6 performs controls with the warm keeping temp., and it is sent to a timer means 8 and a display means 12. The timer means 8 emits a signal to stop current supply at counting-up. When a switch 11 is pushed again during counting, the means 8 is reset, and control is made with normal setting. This permits controls at the set or warm-keeping temp. to enable energy saving. The controlled condition is displayed on the display means 12 to contribute to prevention of malfunction, and thereby the safety is enhanced.

Title: Thermal transfer recording method
Inventor: TAKEDA HIDEICHIRO
IPC: B41F16/00
Filed: 1987-07-08
Abstract: PURPOSE:To record a high quality image, by detecting the temp. of the part where a recording sheet is overlapped with a transfer film and controlling the quantity of heat rays allowed to irradiate according to the detected temp. CONSTITUTION:In recording an image, a temp. sensor 7 measures the temp. of the recording sheet 5 closely adhered to a transfer film 4 or the temp. in the vicinity thereof. This measured temp. is substantially the temp. of the transfer film 4 and, therefore, the temp. sensor 7 measures the temp. of the transfer film 4. When this measured temp. is higher than standard temp., the intensity of the laser beam 9 from a laser beam source 1 is weakened by a moving circuit 8 and a modulator 2. When the measured temp. is low, the intensity of the laser beam 9 is increased. By this method, corresponding to the temp. of the transfer film 4, the quantity of heat necessary for the transfer of the transfer film 4 of that temp. is given by laser beam and a high quality image having definite density is recorded.
