IPC: H04M1/00
Filed: 1992-08-24
Abstract: PURPOSE:To improve the packaging density of a printed substrate by converting telephone terminal control data converted as serial data again into parallel data through an insulating means and supplying the parallel data to a telephone terminal equipment. CONSTITUTION:Control data SS in each 8 bits for controlling the telephone terminal equipment 8 are serially outputted from the PO terminal of an output port 1 by an output conversion circuit 2a. The data SS are successively read out from the input terminal D of a shift register 6 through a photocoupler circuit 3 to be the insulating means and converted into parallel data, which are latched by a data latch circuit 7 and supplied to the control input terminals of the equipment 8. Since insulation between the port 1 and the equipment 8 is executed by the circuit converting the data SS into serial data, it is unnecessary to prepare photocouplers corresponding to the number of bits (the number of terminals of the port 1) of the data SS, reducing the number of photocouplers.

IPC: G05D3/00
Filed: 1993-10-05
Abstract: PURPOSE: To permit calibration with high accuracy by including a calibration sequence, a compensation sequence and an operation sequence. CONSTITUTION: In a calibration sequence, a fist temperature, a predefined current, and a known input value of voltage are transmitted to an A/D converter 38. Next, the actual temperature is detected and read. Then correction values are determined for various inputs and stored values and are stored in a memory. In a compensation sequence, the current temperature is detected and read. Next, compensation values for various inputs at the current temperature are determined from a table and active correction values for various inputs are stored. In an operation sequence, the active correction values determined and stored during the compensation sequence with respect to the necessary inputs are read from the memory and applied so that a converter/positioner device is operable using the corrected input values. Therefore, calibration can be performed with high accuracy.

Title: Variable displacement rotary compressor
Inventor: MATSUDA TOSHIO
IPC: F04C18/344
Filed: 1985-11-07
Abstract: PURPOSE:To control delivery volume with no decrease of compression efficiency, by returning refrigerant gas, given compression work, to an expansion stroke before a suction stroke. CONSTITUTION:Refrigerant gas, given compression work in an operative chamber 16, is returned to the second suction port 18, formed in a part with the operative chamber 16 serving for an expansion stroke, through a bypass passage 21. And while a vane 15 reaches the first suction port 17, being a main suction port of the operative chamber 16, the bypass flowing refrigerant gas acts on the vane 15 with the above obtained compression work serving as expansion work. In this way, the compression work, given to the refrigerant gas allowed to bypass flow for controlling delivery volume, can be effectively recovered as driving force, and the delivery volume can be controlled with no decrease of compression efficiency.

Title: Communication control system
Inventor: NAKATANI YASUHIRO
Filed: 1985-11-07
Abstract: PURPOSE:To decrease the crosstalks and to reduce the deterioration of the certainty of communication by setting proviously the number of receiving timings with which a base station receives the discrimination codes and at the same time setting again at random the timing by which each slave station sends back the discrimination code every time a specific code is received. CONSTITUTION:The number of receiving timings with which the discrimination codes sent back after a base station calls an unspecified station (slave station) are received is synchronous with the transmitting timing of the discrimination code of the slave station. However the timing available at the slave station is limited to just one of those receiving timings and this timing is decided at random. In an example shown in the diagram, the discrimination codes of slave stations A and D are coincident with each other by change at the timing '1'. While the discrimination codes of the slave stations B and C are divided at timings '3' and '4' and transmitted. Then no station has transmission at timing '2'. Therefore the discrimination codes of both stations A and D are received with crosstalk at he timing '1'. Then the discrimination codes of both stations B and C are received in a correct way at the timings '3' and '4'.

Abstract: PURPOSE:To reduce deterioration of a particular oxidation catalyzer layer and achieve a longer life by making the volume of a first stage oxidation catalyzer layer smaller than those of the successive oxidation catalyzer layers from the second stage one on, in a plurality of oxidation catalyzer layer stages. CONSTITUTION:The thickness of a first stage oxidation catalyzer layer 3 is made smaller than those of a second and a third stage oxidation catalyzer layers so that the volume of the first stage oxidation catalyzer layer is reduced and the optimum load value is achieved for the exhaust fuel gas amount and the exhaust air ampount at the time when the fuel cell has a low load. In this way, at the time when the fuel cell has a low load, the combustion is effected in the first stage oxidation catalyzer layer 3 at the optimum temperature without generating higher temperature for the exhaust fuel gas amount and the exhaust air ampount, and successively, unburnt exhaust fuel gas maintains the combustion in the oxidation catalyzer layer 4 and undergoes complete combustion in the oxidation catalyzer layer 5. On the other hand, at the time when the fuel cell has a high load, although the ignition temperature is lowered in the first stage oxidation catalyzer layer 3 due to the exhaust fuel gas and the exhaust air from the fuel cell, the combustion is maintained without extinction, and successively, the combustion is matintained in the oxidation catalyzer layer 4, and complete combustion is achieved in the oxidation catalyzer layer 5.
