Title: Multiplex data sending device
Inventor: ASHIZAWA YUJI
IPC: G06F13/366
Filed: 1986-09-04
Abstract: PURPOSE:To prevent beforehand the overlapping of a time slot designation by providing a multiplex collision detecting circuit to avoid that transmitting data are set to a multiplex position and a means to transmit the transmitting data at the timing of a multiplex setting circuit. CONSTITUTION:A central processing part sets byte data 10000000 and 10000000 caused by the setting error of a software to the comparator 20a of a multiplex collision detecting circuit. The comparator 20a compares both data and coincidence is informed through a signal line 14 to the central processing part. The central processing part recognizes that the time slot designation is overlapped and the time slot is reset to the correct type data 10000000 and 01000000. Thus, since comparator 20a, 20b...20h are all common and multiplex slot designating circuits 21a, 21b...21h are in all common, detection can be executed even when any time slot is overlapped and set.

Filed: 1993-07-30
Abstract: PURPOSE:To ultraminiaturize a filament element and a layout space and to achieve an accurate detection by welding and joining filament to a lead wire which is plated by a corrosion-resistance metal. CONSTITUTION:A lead wire 4 which is plated by a corrosion-resistant metal and an extremely thin filament 8 of a filament element 1 are spot-welded. In this case, the metal at the plated part melts and covers and bonds the joint part, thus preventing the joined part from being disconnected easily for stabilizing state and hence ultraminiaturizing the element 1. The element 1 is laid out at a space 10a of a metal block 10 individually and a flange part 3b is welded to the block 10 airtightly, thus sealing the element 1 into the block 10. At this time, the electrical output of the filament 8 is connected to a detection circuit. Then, when a reference gas and a sample gas are introduced to one space 10a and the other, respectively, the thermal conductivity differs due to introduction of the sample gas. A compensation current flows for keeping constant temperature and a sample is detected from the value, thus ultraminiaturizing the detector and achieving an accurate detection.

Abstract: PURPOSE:To reduce outside diameter runout of a cutter knife approximately to the extent of the out of roundness of outside diameter caused by means of polishing the cutter knife by performing polish machining of each cutter knife upon securing the sleeve of a cuter unit to a polishing arbor. CONSTITUTION:When a sleeve 50 is fitted to a polishing arbor and an oil 55 interior is machined by means of a piston 58, the expansion/contraction wall 56 of the oil chamber 55 protrudes in the inside circumferential direction by means of oil pressure and causes the sleeve 50 to be secured to a polishing arbor.

Abstract: PURPOSE: To easily and simultaneously perform a connecting work by setting an opening of a ground conductor slot of a connector cover larger than the space between a pair of ground conductors, and making the inclinations of a sector guide surface laterally asymmetric. CONSTITUTION: When a push blade 21 is moved in the direction of a connector cover 102, ground conductors 201c-201d are pressed down toward the opening part 19 of a slot 17a as they are in substantially horizontal state. When the blade 21 is further pressed, the left ground conductor 201c moves ahead of the right ground conductor 201d because of the low inclination of a guide surface 20a, and the horizontal relation between both the conductors 201c-201d starts to break. When the blade 21 is further moved down, the conductor 201c is pressed also by the conductor 201d and moved near the lower end of a left inclined surface 20a. Thereafter, both the conductors 201c-201d are moved in substantially vertical state by the blade 21.  When the blade 21 is further pressed, both the conductors 201c-201d are pressed down within the slot 17a in this vertical relation, moved to the bottom part of the slot 17a, and stopped therein.
