IPC: H04L12/40
Filed: 1990-05-15
Abstract: PURPOSE:To allow a master station to confirm whether or not a correct data is sent to each slave station by sending a reply to the master station to each slave station receiving a data from the master station after a time proportional to a station address value of its own station when multi-address communication designating all station addresses is implemented. CONSTITUTION:When a transmission end detection section 11 detects an end of a data of multi-address communication, a timer section 12 is started. After a time proportional to a value of a station address section 14, the timer section 12 controls a reply transmission section 13 so as to send the result of CRC check of a data from the master station by a CRC check section 15 and the station address from the master station from the reply transmission section 13 as a reply signal to the master station. Thus, the master station monitors a reply sent sequentially from each slave station with a time difference and detects a negative reply, then the data is sent again to a slave station having the station address. Thus, the master station confirms whether or not a correct data is sent to each slave station.

Abstract: PROBLEM TO BE SOLVED: To enable design of a semiconductor integrated circuit in consideration of a voltage drop by determining a delay time between standard cells and an interconnection therebetween from an estimated supply voltage while referring to a cell library, and subjecting the circuit to a given processing, when the delay time violates a preset timing limitation. SOLUTION: Delay times 15 relative to supply voltages 17 of standard cells are written in a cell library 1 beforehand for estimation of voltages to be supplied with respect to individual standard cells from the once determined arbitrary arrangement of the standard cells and an interconnection therebetween. By referring to the cell library 1, a delay time 15 between the standard cells and the interconnection therebetween obtained from the estimated supply voltage 17. When a preset timing analyzer 5 judges that the delay time 15 violates a timing limitation, a predetermined treatment is performed. In this way malfunctions of a chip caused by the drop in supply voltage can be avoided at a design stage, thereby enobling design of circuits while taking the voltage drop into account.

Abstract: PURPOSE: To increase the space cooling or heating capacity, by employing an arrangement capable of injecting a coolant into a cylinder only at a limited period during compression stroke of a reciprocating compressor.  
     CONSTITUTION: In a compressor shown in the drawing, a valve means consisting of a valve plate 30, spring 31 and portion for guiding the valve plate 30 is place in an injection passage 29 at one end thereof located on the side of a cylinder 3, in the manner that it can open and close the passage 29. That is, the valve means is  opened by a high-pressure or medium-pressure coolant carried to the valve means,  when pressure in the cylinder 3 is raised to a certain level after expansion stoke of  the compressor. Here, the passage 29 is formed at such a position lower than the  level where the valve means is forced to open by pressure in the cylinder 3 during  expansion stroke of the compressor, so that the coolant is not injected into the cylinder during expansion stroke. Since the compressor of this invention is arranged as avobe, high-pressure or medium-pressure coolant can be injected into the cylinder 3 only during compression stroke without lowering the efficiency. At the same time, it is enabled to increase the capacity and efficiency of space cooling or heating by using the compressor of this invention in combination with a multiple effect cycle.
