Title: Data transmission method
Inventor: KASHIDA MOTOICHI
IPC: H04B14/06
Filed: 1984-06-28
Abstract: PURPOSE:To prevent transmission of wrong data for a long period in a decoding mode by transmitting the data on the estimated value used for conversion to the head data within a group to a prescribed position of an estimated differential data string. CONSTITUTION:The input information data A is converted into the DPCM data B by a coder 7 and supplied to a selector 8 together with past (t) pieces of data C used for said conversion. Then the data B is outputted selectively and this output is supplied to an error detection/correction code coding circuit 10 and a synchronizing signal generating circuit 11. The output of the circuit 11 converts the data group containing plural pieces of data in a data series where the data at the preceding and next positions have correlation with each other into an estimated differential data string in a format where the data on the estimated value used for conversion is added to a prescribed position of the estimated differential data string against the head data within a group. Then the signals are transmitted via a modulation circuit 12.

Title: Digital demodulator and its demodulation method
Inventor: SUGITA YASUSHI
IPC: H04L27/22
Filed: 1999-05-14
Abstract: PROBLEM TO BE SOLVED: To properly correct even a varying phase jitter and to secure stable demodulation for a long period of time by receiving the output of a phase error detection means and controlling the gain of a loop filter by a phase jitter suppression control signal. SOLUTION: A phase error detection circuit 104 detects the position of a symbol on a complex surface from a complex signal containing two input signals 144a and 144b, i.e., the sin and cos components respectively, decides a phase from the angle of the symbol position to compare this phase with an original reference phase and outputs a phase error signal 146 according to the difference between both phases. The signal 146 is inputted to a code decider 111 of a phase jitter suppression circuit 105, a multiplier 123 and two gain control circuits 131 and 132 of a secondary loop filter 106 respectively. The parts 131 and 132 decide the loop gains of the phase locked loops of a demodulator and can control the phase jitter by adaptively controlling those gains via a phase jitter suppression control signal 151.

Title: Absorptive refrigerator
Inventor: NOMURA KAZUO
IPC: F25B15/00
Filed: 1993-05-13
Abstract: PURPOSE:To improve the heat exchanging efficiency and improve the performance factor of an entire absorprtive refrigerator in the refrigerator having a heat exchanger between an absorber and a generator, i. e., a GAX function. CONSTITUTION:A generator 5 generates refrigerant vapor 7c from concentrated liquid 2b to form dilute liquid 2b. A second absorber 207 auxiliarily applies absorption heat for sbsorbing refrigerant vapor 7b by the liquid 2b to a heat exchanger 62 for cooling/heating only at the time of heating, and applied directly atmospheric heat by a heat exchanger 213 to the liquid 2a. A third absorber 217 cools the absorber 217 and a condenser 61 directly by air cooling at the time of cooling. Since the exchanger 217 directly utilizes the atmospheric heat at the time of heating and directly utilizes air cooling at the time of cooling, the heat exchanging efficiency is improved by an amount not using secondary heat fluid.
