Patent JP-H06230968-A (JP)
Title: Branching controller
Inventor: KAWAI ATSUSHI
IPC: G06F9/38
Filed: 1993-02-01
Abstract: PURPOSE:To shorten an execution time by performing efficient pipeline processing when a program including a branch instruction based upon conditions is executed. CONSTITUTION:A branch destination instruction code is stored in a branch destination table 6 corresponding to the instruction address of the branch instruction. An instruction code 2A read out of a program memory 2 with an instruction address 1A generated by a program sequencer 1 is temporarily stored in a 2nd instruction register 14 and the branch destination instruction code read out of the branch destination table 6 is temporarily stored in a 1st instruction register 13. A selector 15 selects one of the outputs of the instruction registers 13 and 14 and supplies it to an instruction decoder 4. Consequently, the need for a read phase for reading the branch destination instruction out of the program memory 2 is eliminated and the pipeline processing can be executed without any deviation in timing.

Title: Magnetic disc device
Inventor: KUNO HIROYUKI
IPC: G11B21/02
Filed: 1984-02-29
Abstract: PURPOSE:To attain stable head positioning with high accuracy by increasing the surging frequency of a coil spring of a support supporting a head arm and a voice coil so as to prevent vibration from being delivered to the carriage system. CONSTITUTION:Plural holes 15 to surround a shaft 4 as a ring-form are porivided to the upper end of a thick part 14 of a support 13 supported by a shaft 4 having the head arm 6 and the voice coil 7 at the outer circumference and implanted onto the base 3 and the coil spring 16 is inserted to each hole 15. The diameter and length of the coil spring 16 are designed to small values so that the surging frequency is a frequency far higher than the resonance frequency of the mechanical system such as the carriage or the like. Thus, the vibration of the coil spring 16 does not vibrate the mechanical system such as the carriage or the like. After the coil spring 16 is inserted to each hole 15 of the support 13, the assembly is supported by an upper bearing 10 via a ring washer 17.

Abstract: PURPOSE:The bottom of the extractive distillation column is divided into two sections to send the liquid in one section heated with a reboiler to the other and the hydrocarbon vapor at the top of the solvent recovery column is compressed and sent to the extractive distillation column, thus separating a mixture of C4 and C5 hydrocarbons with energy saved. CONSTITUTION:A hydrocarbon mixture of 4 or 5 carbon atoms is separated by means of an extractive distillation column and a solvent recovery column wherein the bottom of the extractive distillation column A is provided with a section wall G to divide the bottom into two sections. The liquid taken out of the one section (a) is heated with the reboiler E and made to turn back to the other (b) and the liquid from the bottom is fed to the solvent recovery column B. The hydrocarbon vapor from the column top is compressed with compressor C and made to turn back to the extractive distillation column. The installation of the reboiler and the vaporization at the bottom of the distillation column make it possible to minimize the size of the compressor and lower the capacity greatly. Electric energy can be saved by 42%, while the total energy by 6.5%.
