Abstract: PURPOSE:To extremely improve dehumidifying ability by making the maintenance easy and sufficiently utilizing the hygroscopicity of moisture absorbent. CONSTITUTION:The number of revolution of a fan motor 7 at the time of moisture absorbing is set smaller than that at the time of regenerating so as to make an air blowing quantity per hour to the moisture absorbent 9 at the time of moisture absorbing smaller than that at the time of regenerating. At 442 the time of regenerating, regeneration time and heat radiating time are minimized by making the air blowing quantity to the moisture absorbent 9 larger and, at the time of moisture absorbing, the moisture absorbing quantity per hour is increased by making the air blowing quantity at the time of moisture absorbing smaller than that at the time of regenerating.

Title: Synchronizing separator circuit
Inventor: AOKI MUNEO
IPC: H04N1/08
Filed: 1987-08-12
Abstract: PURPOSE:To make the width of a synchronizing pulse constant with a small sized circuit by using a diode provided to a base circuit of an inverting amplifier transistor(TR) circuit so as to pass a small amplitude composite video signal as it is and block an external synchronizing signal with a large amplitude. CONSTITUTION:A composite video signal or an external synchronizing signal V1 outputted from an emitter of a TR Q1 is inputted to a cathode of a diode D4 through a resistor R2 and a capacitor C1, led to ground via a resistor R3 and connected to a cathode of a diode D3. The anode of a diode D4 is connected to a power supply via a base of a TR Q2 and a resistor R9 and a minute current flows through the diode D4. If an excess synchronizing signal is given to the input, a prescribed amplitude portion passes through the diode D4 and inputted to a base of the TR Q2 and the level in excess thereof is cut off with the reverse-biased diode D4. Thus, the synchronizing signal with a small amplitude is detected surely and an external synchronizing signal with a large level is sliced to make the width of the synchronizing signal constant thereby preventing the positional change in the picture.

Title: Driving device for multi-bit heat generating circuit
Inventor: YOSHIDA YUTAKA
IPC: H03K17/693
Filed: 1989-08-04
Abstract: PURPOSE:To unify the calorific value of respective heat generating resistors by providing a feedback means, regulating the ON-times of respective switching means in accordance with the values of ON-resistances. CONSTITUTION:A drive control signal (a1), having a pulse width ta, is inputted into one terminal of a NOR gate 36i from a logic unit while a feedback signal (g1) is inputted into the other terminal of the same. Here, all of the gate delay times of logical operation circuits 31i, 32i, 36i, 37i are deemed equal to a value (tr). A delay signal (b1) is converted by an inverter 37i into a gate signal Ci. A transistor Ti becomes ON-state while synchronizing with the 'H' level of the gate signal Ci by the delay of a turn-ON period of time (tPHL) and becomes OFF-state by the delay of a turn-OFF period of time (tPLH). A delay time from the rise-up of the drive control signal (ai) until the transistor Ti becomes ON-state is 2tp+tPHL while the delay time from the breaking of the drive control signal (ai) until it becomes OFF-state is 4tp+tPLH+tp. Accordingly, a difference between TON and Ta becomes tp+tPLH-tPHL+2tp. According to this method, the ON-time is regulated automatically even when a variability exists in the ON-resistances, whereby valiability in concentration may be eliminated.
