Title: Induction heater
Inventor: ASADA KAZUHIKO
IPC: H05B6/06
Filed: 1990-02-15
Abstract: PURPOSE:To detect the magnitude of a load on a heating coil in a short time by alternately turning on and off first and second inverse conduction switching elements connected to a DC power source and detecting the attenuation of current amplitude in a load circuit. CONSTITUTION:When heating operation is carried out, a control circuit 15 controls the gate/emitter of elements 6, 7 high alternately thus turning the elements 6, 7 alternately ON/OFF. Voltage VGE2 between the gate and emitter of the element 7 becomes zero at time t1 and thereafter voltage VGE1 between the gate and emitter of the element 6 becomes positive. Then, the element is turned on, and voltage of a DC power source 1 is applied to a load circuit 12 so that resonance current begins to flow. A resonance capacitor 14 at time t2 is charged to lower the voltage VGE1 between the gate and emitter of the element 6 to zero and set the load circuit 12 in a short circuit state. Thus, energy supplied between the time t1 and time t2 causes a damping oscillation in the load circuit 12 under the short-circuited condition. The damping oscillation of the current IL is determined by the condition of the load located on a heating coil 13, so that the magnitude of the load on the heating coil can be detected in a short time.

Filed: 1979-03-29
Abstract: PURPOSE:To realize the signal detection and the like only by the amplitude spectrum, by transmitting the input signal through two linear circuits featuring the different characteristics from each other and then averaging the product of these two outputs. CONSTITUTION:Output y(t) obtained when input signal x(t) is applied to linear circuit 1 such as the filter or the like is turned into the input of multiplier 2. On the other hand, signal x(t) passes through linear circuit 4 of impulse reply h(t), and the output z(t) is turned into the input of multiplier 2 along with output y(t) of circuit 1. Then product y(t)Xz(t) of the output of two linear circuits 1 and 4 undergoes the averaging through averaging circuit 3 (with sufficiently long time constant secured), and thus the real average is obtained in the form of output m of the device. As a result, no output of the device exists substantially in the case of only the noise although the overlapping area may exist in the frequency region for both the signal and the noise, and the output of the finite scale is caused only when the signal to be detected exists.

Title: Mechanism for feeding ink ribbon
Inventor: ISOBE MINORU
IPC: B41J33/388
Filed: 1979-03-29
Abstract: PURPOSE: To feed an ink ribbon without a motor for exclusive use by performing engagement and disengagement of a planet gear with a ribbon-spool driving gear corresponding to the normal and reverse rotation of a spacing motor.  
     CONSTITUTION: A spacing motor 4 is rotated in the direction of an arrow A and by means of a timing belt 5 a driving gear 11 is rotated in the clockwise direction. This rotation is transmitted to a ribbon spool 9a through the intermediary of a planet gear 12, thereby an ink ribbon 10 being sent from spool 9b to spool 9a. And when an eyelet 19 of the end part of the ribbon 10 is caught by the end part 14a of a ribbon-feeding reversely-rotating bar 14, the bar 14 moves to the right until the eyelet 19 is released and rotates the motor 4 in the direction B to rotate further the gear 11 in the anti-clockwise direction. This makes the gear 12 move slightly on a connecting arm 13 biased by a detentespring 15 to release the ribbon 10 from the engagement with the spool 9a and thus stops the same. And then, the arm 13 being changed-over by means of the spring 15 as well we the rotating movement of the gear 12, the gear 12 is engaged with the spool 9b, thereby the ribbon 10 being sent from spool 9a to spool 9b.
