Title: Constant temperature bath
Inventor: DOUMAE MITSUHIRO
IPC: G05D23/19
Filed: 1983-11-24
Abstract: PURPOSE:To attain low power consumption and high efficiency and also to eliminate the need for heat dissipation of a power transistor (TR) by mounting the power TR controlling a current flowed to a resistor on a heat sink whose temperature is kept constant. CONSTITUTION:The power TR8 condrolling a current flowing to a heat generating resistor 1 is mounted on a heat sink 2 whose temperature is kept constant.

The effect is especially eminent when only the voltage VCD applied to the resistor has a relation of VCD<1/2. VPS, where VPS is a power supply voltage VPS. Through the constitution above, no heat dissipation of the power TR is required, unnecessary heat is not given even if the TR is placed at the same location as that of other devices and the heat amount is controlled with good accuracy.

Title: Adaptive transversal filter
Inventor: KOSHIKAWA MASAMI
IPC: H03H15/00
Filed: 1985-10-07
Abstract: PURPOSE:To revise a stable tap coefficient even when a signal with a high peak level is inputted by continuing the correction control corrected by a correction coefficient in response to the level of the peak by a sample time of tap number of a tap delay line. CONSTITUTION:An instantaneous power obtained by a multiplier 10 and an output of a power calculator 4 are multiplied with CNP/N at a multiplier 11, a peak factor CPK being a ratio of the result to the mean power multiplied with the peak factor CNP of a normal signal is obtained by a divider 13 and the result is inputted to a discrimination/timer section 15 and a storage device 14. When CPK>1, the discrimination/timer section 15 discriminates it as a signal with a high peak, a multiplier 12 multiplies the peak factor CPK stored in the storage device 14 and the total sum of the power of the signals in a tap delay line 1 and outputs the result. The output of the total sum of the corrected power is given by a timer of the discrimination/timer section 15 during the hang-over time of the sample time of the tap number of the tap delay line 1. Thus, even when a signal having a high peak is inputted, the tape coefficient is revised stably.
