Title: One tip microprocessor
Inventor: MIYAKE TOMU
IPC: G06F15/78
Filed: 1987-10-06
Abstract: PURPOSE:To shorten a testing time by providing a direct-coupling means to directly couple an internal bus and an external bus. CONSTITUTION:When data to instruct the start of a testing mode is added to a CPU 4, the CPU 4 decodes the data, outputs a signal SDBOUT to indicate that the testing mode is in the middle of an execution to a direct-coupling means 14, and the direct-coupling means 14 directly couples an internal bus BUS1 and an external bus BUS2. Thereafter, the CPU 4 executes, for example, an INport instruction, and outputs an instructing signal to load the data stored in a register 7 of a peripheral circuit 6 onto the internal bus BUS1. The data loaded on the internal bus BUS1 is sent through the direct-coupling means 14 which is already direct-coupled to the external bus BUS2, and observed by a tester. Thus, an internal condition can be observed in a short time, and the testing time can be shortened.

IPC: G02F1/1345
Filed: 1994-10-18
Abstract: PURPOSE: To decrease labor for removing an adhesive remaining at a spot where a driving IC is peeled off, and to reduce the wire defective being due to static electricity generated at the time of removing the adhesive. CONSTITUTION: In the case where nonconformity being due to the badness of a driving IC itself or the bad connection of the driving IC or the like occurs to cause the badness of display, the driving IC at a spot where the nonconformity occurs is first peeled off from a IC mounted part 7.

Filed: 1987-10-07
Abstract: PURPOSE:To improve a simultaneous callability by estimating a general intensity (alpha) of an acoustic system echo path between a reception attenuator output and a transmission attenuator input and a line system coupling intensity (beta) between a transmission attenuator output and a reception attenuator input, calculating the attenuating quantities of attenuators, and setting a reception threshold and a transmission threshold. CONSTITUTION:Based on a reception amplitude ratio from a reception amplitude ratio calculating part 9 to subtract a transmission input signal amplitude with a reception output signal, the (alpha) between the output of a reception attenuator 2 and the input of a transmission attenuator 7 is estimated by an (alpha) estimating part 9, and the (beta) is estimated by a (beta) estimating part 12 in the same way. Based on such estimates (alpha) and (beta), the reception threshold and transmission threshold are set by a threshold setting part 14, and a small attenuating quantity is calculating in a range in which howling is not generated by an attenuating quantity setting part 13. Through a transmission/reception deciding part 15, the attenuating quantities of the transmission attenuator 7 and reception attenuator 2 are controlled at the time of receiving and transmitting, respectively. By such constitution, even when the (alpha) and (beta) are changed according to the change of the position of a microphone and a loudspeaker, the reverberation characteristic of a room, etc., the simultaneous callability can be improved without a reception blocking, a transmission blocking, a work head cut, and the howling, etc.

During this refining, CaO, etc., as a slag-making agent is added and the molten slag having 0.8-2.5 basicity is limited to <=50kg/ton of the molten steel.  The molten stainless steel is tapped from the converter and the Cr2 O3 -containing slag is left in the furnace for use in the next decarburize-refining of the Cr-containing molten iron, and the molten slag is reduced into Cr by C in the high carbon and Cr-containing molten iron and recovered as Cr in a high yield.
