Abstract: PURPOSE:To obtain a color developer sheet for a pressure sensitive paper having excellent performance, coating properties and printability, by incorporating a polyvalent metal compound of a co-condensation resin comprising salicylic acid and an alpha,alpha'- dialkoxy-p-xylene as main monomeric components and a calcium salt of a higher fatty acid. CONSTITUTION:A color developer sheet for a pressure-sensitive paper comprises a polyvalent metal compound of a co-condensation resin comprising salicylic acid and an alpha,alpha'-dialkoxy-p-xylene as main monomers and a calcium salt of a higher fatty acid. The color developer sheet has color developing properties (color developing speed and developed color density) satisfactory for practical use, and developed color images obtained have such resistance as not to be easily faded by water, plasticizers or rays. In addition, resistance to after yellowing upon irradiation with light is markedly enhanced, and a tendency toward after-yellowing of a paper surface in an oxidizing gas atmosphere represented by NOx which is the problem in use of the pressure sensitive paper, is not observed at all. The color developer sheet shows a marked improvement in the tendency toward lowering in color developing performance (particularly, color developing speed) after long-time preservation or after preservation at high temperature.

Title: Bus collision avoiding system
Inventor: TAJIRI YUJI
IPC: H04L12/40
Filed: 1989-01-19
Abstract: PURPOSE:To prevent the collision of a retransmission packet by generating protection time till each communication equipment retransmits a packet based on an address specific to each communication equipment when information sent by plural communication equipments collides on a bus. CONSTITUTION:When a collision detection means 101 detects collision consecutively for a prescribed number of times, an initial setting means 102 sets an address given to its own communication equipment 100 to a random number generating means 103 initially. The random number generating means 103 is activated by initializing the address of the its own communication equipment 100 from the initial setting means 102 and generates a random number. A protection time generating means 104 generates the protect time corresponding to the random number generated by the random number generating means 103. After the protection time generated by a protection time generating means 104 elapses, the communication equipment 100 sends the information representing the detection of collision by the signal detection means 101 to a bus 200 again. Thus, the retransmission period differs from each other and the possibility of the collision of the retransmission packet again is eliminated.
