Abstract: PURPOSE:To make facsimile communication even when a called subscriber is not hooked off at the time of manual receiving by making a measuring device control a manual receiving-automatic receiving switching device basing on a reference value for which a sound signal is set beforehand. CONSTITUTION:When a bell sound signal of 16Hz is received at the time of manual receiving, the incoming is detected by a bell sound signal detecting circuit 24 and sounds the bell of a telephone set 23. Every time incoming is detected once, a pulse signal is outputted to a counter 30, and the counter 30 counts number of times of incoming of the sound signal. A reference number of counts is set to the counter beforehand, and when incoming of bell sound signals is continued without the telephone 23 is hooked off, and the counter 30 counted to the reference count number, a pulse signal is outputted to a signal line 27, and inputted to the main body of a facsimile equipment 26. The main body of the facsimile equipment operates a relay 22 on input of the pulse signal, and switches a telephone circuit from the telephone 23 side to the body 26 of the facsimile equipment side.

Title: Gear line structure of analogue electronic timepiece
Inventor: TAKEDA KIYOTO
IPC: G04B13/02
Filed: 1991-04-16
Abstract: PURPOSE:To prevent rattling of a needle gear in the direction of rotation and also to prevent rattling of the gear in the axial direction while the gear is not driven by providing an elastic portion to a transmission gear by means of integral molding or the like, and providing a needle receiver with a plurality of recessed or projecting portions which mesh with the elastic portion. CONSTITUTION:An axially movable position-regulating elastic portion 8 is provided to the toothed portion of a fourth gear (needle gear) 5. The end portion 8a of the elastic portion 8 meshes with plural (60) recessed portions 9 provided in a needle receiver 2 which holds the fourth gear 5, so that the stopping position of the fourth gear 5 is regulated. The elastic portion 8 is bent at least in the direction of its axis when intermittently moved by a step motor, and also when the rotor 3 of the step motor is in its statically stable position the recessed portions 9 are engaged with the elastic portion and thereby the stopping position of the fourth gear 5 can be regulated regardless of the amount of backlash provided between gears and so the position of the fourth gear can be surely detected per second. When not driven the fourth gear 5 is prevented from rattling in the direction of its axis, thus reducing to a large extent the probability of a clock being stopped by sliding of needles against each other. Concerning disturbance, the danger of the needles being jumped is eliminated.

Filed: 1981-06-02
Abstract: PURPOSE: To set a substrate potential to almost constant value, independently of a power supply voltage, by detecting and comparing the substrate potential and controlling the oscillation of an oscillation circuit from the result.  
     CONSTITUTION: In an oscillation circuit 21, the oscillation is started or stopped with a level of an external oscillation control signal CNT. An output from the circuit 21 is given to an anode of a diode 23 and a cathode of a diode 24 via a capacitor 22 respectively and the anode of the diode 24 is connected to a substrate 25. if a substrate potential VBB does not reach a desired negative potential, the signal CNT is "O". Thus, the circuit 21 is oscillated and the potential VBB is increased negative. When the VBB reaches a desired negative potential, the signal CNT is inverted and the oscillation of the circuit 21 is stopped. When the absolute value of the potential VBB is smaller, the circuit 21 again oscillates.

Abstract: PURPOSE:To reduce the effect of the noise, by slicing the sawtooth wave voltage with the output voltage level and turning on and off the switching element to obtain the coincidence between the phase of the pulse and the off-timing of the switching element. CONSTITUTION:The commercial power supply voltage AC100V is dropped by a power supply transformer 1 and a rectifying circuit 2 and rectified to the DC input voltage Ei to be applied to a choke coil L1 of an output circuit 3. The voltage Ei is then fed to a load circuit 4 to actuate a horizontal oscillating circuit 4a and a horizontal output citcuit 4b. Then the flyback pulse Va is aupplied to the base of a transistor TRQ4 of a sawtooth wave voltage producing circuit 5. In this case, the coincidence is obtained between the phase of the pulse and the off-timing of a switching element. As a result, the noise caused by the OFF of the switching element can be limited within the horizontal blanking period.

When 3 or -3 appears, encoding is executed by 4 bits while switching the code to a code 3 and when 5 or -5 appears, encoding is executed by 5 bits while switching the code to a code 4. Namely, when the transformation coefficient in a range not to be encoded by the code currently under use appears, the code is switched to the code with the wide range and in the other case, the conventional code is used with the small number of required bits. Then, when the code is switched, a switch code is inserted corresponding to the code table so as to know the switch of the code.
