IPC: H04B1/40
Filed: 1988-05-21
Abstract: PURPOSE:To essentially and remarkably reduce a CPU abnormal operation by intermittently starting a CPU to cooperate with a simplex radio set by utilizing an existing squelch circuit. CONSTITUTION:When a carrier is received, the voltage of a node aNa goes to H. An output voltage V2 of an AVR130 is H. A gate signal to turn on a switch 123 is outputted from a squelch circuit 122 in a delayed state for approximately 1ms by the reception of the carrier. The gate signal of the circuit 122 is inverted at an inverter 126 and impressed to a comparator 203, a node dNd of an output part goes to H with a delay for its operating time, this signal is impressed to a reset terminal 202 of a CPU201, and the mode of the CPU201 is shifted from a sleeve mode to an operation mode. Since the input signal continues for one second, the CPU201 is operated during the time and after that shifted to the sleeve mode again, and the mode is maintained by an AVR204. On the other hand, when the PTT button of the radio set is pressed, the voltage of the AVR130 becomes L, an inverter output also becomes L while the button is pressed, and a comparator output H makes the CPU into the operation mode.

CONSTITUTION:Firstly, the open end of a cylindrical primary stock 9 made of thermoplastic synthetic resin is belled under the state that the end is heated at a temperature higher than the softening point of the resin by 10-20 deg.C into a worked portion 4 so as to leave the remaining portion of the primary stock 9 as a can shell 2. Secondly, the worked portion 4 is pressed so as to form an outer flange 3 curved normal to the can shell 2 under the state that the outer peripheral surface of the worked portion 4 is heated at a temperature lower than the softening point of the resin by 10-20 deg.C and its inner peripheral surface is heated at a temperature higher than the softening point of the resin by about 20 deg.C and at the same time the open peripheral edge of the can shell 2 is cooled. In this case, the radius of curvature ranging from the inner surface of the can shell 2 to the surface of the outer flange 3 is made to lie within the range of 50-100% of the radius of curvature ranging from the outer peripheral surface of the short cylindrical body 6 of a metal top plate 5 to the surface of a flange 8. The outer flange 3 is formed integrally with the can shell 2 by solidifying the outer flange 3 by forced cooling.

IPC: G05F1/56
Filed: 1979-09-26
Abstract: PURPOSE: To prevent a malfunction when the electric power supply is turned on, by separating the control electric supply circuit one by one, and also controlling the making time adequately.  
     CONSTITUTION: When voltage E(v) is applied, a current starts to flow immediately into the light emission diode 621, and a phototransistor 611 conducts, therefore a transistor 31 also conducts, and the output voltage e 1 (v) equal to Zener voltage of a Zener diode 41 is output. On the other hand, a current i 3  flowing in the light emission diode 622 is increased slowly by the influence of a capacitor connected in parallel, therefore the phototransistor 612 does not conduct instantaneously but conducts after a prescribed period of time decided by the capacitor 71 and the resistor 23. Accordingly, the voltage e 2 (v) which is output to the terminal 52 is output, being delayed by a prescribed period of time after the input voltage E(v) has been applied.
