Abstract: PROBLEM TO BE SOLVED: To provide an absorption refrigerating plant which has enhanced a result coefficient when viewed as a device on the whole by enriching the refrigerant concentration of a refrigerant vapor to be given to a condensation functional area. SOLUTION: A first heat operation fluid (cooling water) 35a is divided into a pipeline 20A and a pipeline 30B, thereby cooling an absorption function area (an absorber) 1 and a condensation function area (condenser) 11. The first operation fluid 35a after the condensation functional area 11 is cooled, is branched into a pipeline 20C3 and a pipeline 20C4 so that the fluid may be provided to a heat exchanger tube of a reflux area 205F adapted to cool the refrigerant vapor 7a to be given to the condensation function area 11 from a generating functional area (generator) 5.  The flow rate of the first operation fluid 35a, which is given to the reflux area 205F is controlled with a temperature control valve 241 so that the temperature of the refrigerant vapor passing through the pipeline 10 may be turned to a specified value, which makes it possible to enrich the concentration of the refrigerant. Preferably, the reflux area 205F should be formed with a heat exchanger which is different from the generating function area 5. This construction makes it possible to enhance the performance coefficient viewed as the device on the whole without hindering the absorption functional area 1 by the first heat operation fluid 31a.

Title: Agc amplifier circuit
Inventor: AKIMURA HIDEHARU
IPC: H03G3/30
Filed: 1991-05-24
Abstract: PURPOSE:To improve the noise resistance with an AGC amplifier circuit by applying the negative feedback control to the amplification gain and then giving the controlled gain to a bend gap constant voltage circuit so as to set an AGC signal at a fixed reference level. CONSTITUTION:The negative feedback control is applied to the amplification gain through the differential pairs of bipolar transistors Q1-Q2...Q7-Q8 so that an AGC signal is set at e reference level Vref. Thus an AGC amplifier circuit 3 amplifies the read signal Vin which is preliminarily amplified up to a fixed amplitude level set by the level Vref. Therefore a stable gain control operation of the circuit 3 is kept because the level Vref to be set can be kept constant despite the fluctuation of the power voltage Vcc caused by the noises. As a result, the noise resistance of the circuit 3 is improved and especially the interruption of output signals caused by the power noises can be prevented.

Title: Hologram display body
Inventor: USAMI TAMOTSU
IPC: G03H1/26
Filed: 1991-05-24
Abstract: PURPOSE:To obtain the hologram display body which can be observed even in plural directions by setting plural directions of reference light and recording information of images on a hologram, direction by direction. CONSTITUTION:A display part 51 is formed of an assembly of recording bodies 52-55 where pieces of information of images in the directions of the reference light are fractionized and recorded, direction by direction. Consequently, when the display part 51 is irradiated with light, the information corresponding to the light irradiation direction is recorded, the recording bodies 52-55 reproduce the information of the respective images, and the display part 51 as the assembly of the recording bodies 52-55 displays one image. Thus, the directions of the reference light are pluralized and the information of the image in the directions are fractionized and recorded on the hologram in accordance with each directions, so the hologram display body which enables the beautiful hologram to be observed in the directions is obtained. Every time the direction of the reference light is changed, the stereoscopic information of the direction is varied and recorded, so the area (visual area) wherein the reproduced image of the hologram can be observed is not narrowed down in the longitudinal direction.

Title: Reproducing device
Inventor: UEKI KEIJI
IPC: G11B20/14
Filed: 1987-06-16
Abstract: PURPOSE:To selectively eliminate the effect of the distortion included in an input signal by detecting data from in input signal by using the oscillating output of a PLL as a clock signal and subjecting the PLL to a synchronous operation by the input section of the synchronous signal, as well. CONSTITUTION:When a sample-hold circuit 6 is in non-operation state, a PLL 1 compares an input signal Sin with the oscillating output of a VCO 4 by a phase comparator 2, giving the compared output voltage to the VCO 4 as a control voltage via an LPF 3, as well. The VCO 4 thus becomes in a synchronous state of oscillating the clock signal phiS synchronized with the signal Sin. On the other hand, when the circuit 6 becomes in an operation state, the PLL 1 becomes in a self-traveling state of executing an oscillation operation independing on the signal Sin with the control voltage given to the VCO 4 being held by the circuit 6. A data detection means 5 detects the data from the signal Sin by using the signal phiS, outputting a reproducing data Dout. The error of reproducing data is thus reduced by removing the effect of the distortion included in the input signal.
