Filed: 1984-01-23
Abstract: PURPOSE:To carry out efficiently information transmission from a slave station to a master station in terms of remote control system by demanding monitoring information transmission automatically from a master station to the slave station which does not receives monitoring information after exceeding a certain period. CONSTITUTION:When a slave station 2 detects a status change of a monitoring information 3 in a monitoring information status change detection circuit 11, it transmits immediately a station information 4 to a master station 1 from a station information generating circuit 10. When the information 4 is received in a station information receiving circuit 7, a timer 8 is reset, and the slave station 2 starts again. If the information 4 is not received within a period set by the timer 8, a station information transmission demand signal 5 is transmitted from a station information transmission demand signal generator circuit 6 to the slave station concered. When the signal 5 is received in a station information transmission demand signal receiving circuit 9 of the slave station concered, the slave station 2 transmits the informations 4 from the circuit 10 to the master station 1. Thus the slave station 2 can immediately transmit the information 4 to the master station 1 regardless of other slave stations.

IPC: H05K3/34
Filed: 1991-01-31
Abstract: PURPOSE:To prevent the generation of solder bridge satisfactorily when mounting multi-leg electronic components on a wiring board. CONSTITUTION:A plurality of lands, which are designed to connect electrodes 5 of an SOPIC 4, are continuously installed to a wiring board 1. The land 2a located at the farthest rear is selected out of the lands 2 and further extended. There is installed an extension material 6 having a solder-adhered side 6a higher than the land surface on the rear end continuously. This wiring board 1 is dipped into a solder ejection section at a specified slanting angle to be soldered. During this soldering work, the solder adhering side 6a of the extension member 6 is dipped to the end. In other words, the solder is stretched up to the part of the solder adhering side 6a so that the solder may adhere equally and properly between the lands 2, which precede the land 2a at the farthest rear end. It is, therefore, possible to prevent the generation of solder bridge between a plurality of electrodes 5 for multi-leg electronic components 4 which correspond to the proximity of the land 2 at the farthest rear end.

Filed: 1988-01-20
Abstract: PURPOSE:To suppress the progress of wear caused by the drop of sharpness to a possible extent and prevent the loss of seramics tip caused by the collision of chips by changing the chamfering width on the way and also controlling the distance to a changing point and the chamfering width suitably. CONSTITUTION:In a part where the distance from the contact point a of a straight edge 2 for the curved edge 1 of a nose part is apart more than 14% of the length L of the straight edge 2, the chamfering C1 width made on the straight edge part makes bigger than the chamfering C2 width on the other edge part. The chamfering C1 width is set more than 0.20mm in the rake surface 3 side X and more than 0.7mm in the escape surface 4 side Y and the chamfering C2 width is set more than 0.1mm and less than 0.2mm in the dip up surface 3 side Z respectively. Consequently, the loss of the seramics tip caused by the collosion of the chips can be prevented without the acceleration of wear caused by the drop of sharpness. Therefore, the high reliable breakage resistance and wear resistance can be displayed for the high load and high speed cutting and can contribute to the improvement of efficiency for cutting.

Abstract: PURPOSE:To effectively perform the effect of powder particles by covering a core material made of synthetic fiber or the like with synthetic resin heated with powder particles of metallic powder, cutting the surface by wire wheel blasting or sandblasting, and exposing part of the buried particles. CONSTITUTION:A core material 1 is introduced into a die 3 attached to the end of an extruder 2. Resin kneaded with powder particles is introduced to the extruder 2, and the material 1 is covered with it by the die 3. The covered material 1-1 from the died 3 is introduced through an air gap 4 to coolant 5. The material 1-1 cooled by the coolant 5 is grounded partly on the surface by wire wheel blasting 6, 6-1, and part of the buried particles is exposed. In this case, to cut only the resin raised with the particles, it is adjusted by the type, rotating speed and contact pressure, etc. of the blasting. Thus, the long term effect of the kneaded particles can be expected. The kneaded particles have excellent retentivity for the covering resin, which is not exfoliated even under severe available condition.

Abstract: PURPOSE:To realize quick pull-in for the timing phase of sampling and at the same time to reduce the initial shift of said timing phase, by detecting the time point when the electric power is maximum for a complex base band signal obtained by demodulating a received signal and then deciding the rise point of an output waveform of a phase locking oscillator to which the sampling clock phase is fitted on the basis of the above-mentioned time point. CONSTITUTION:A frequency dividing circuit 14 is cleared with the output of a peak detecting circuit 12 in a period during which a signal 18 is set at ''1'' at the beginning part of a received signal. A sampling clock CP has a rise with the fall of the next rectangular wave CK. Thereafter the clock CP has a rise with each 1/2 period of modulation. Therefore the input signal is sampled by a sampling circuit 15 and with the rise of the clock CP. A phase shift calculating circuit 16 completes quickly the pull-in of phase for a phase locking oscillator 17. Furthermore an initial shift can be reduced for the timing phase of sampling.
