Title: Arithmetic system for floating decimal point
Inventor: ASANO SADAJI
IPC: G06F7/00
Filed: 1988-01-13
Abstract: PURPOSE:To avoid the disturbance of pipeline processing by finishing the process of >=3 digits earlier by one cycle in case of the normalization quantity of >=3 digits and then holding a stage preceding a normalization stage in case of the normalization quantity of >=3 digits respectively. CONSTITUTION:An arithmetic system for floating points consists of a 1st normalization shifter means 71 which shifts all digits of an intermediate solution received from an addition/subtraction stage 5, a means 6 which holds data normalized by the means 71 via a normalization stage, a 2nd normalization shifter means 72 which shifts <=21 digits of the intermediate solution, a means 8 which sends the data normalized by the means 72 to the next stage, and a signal production means 1 which produces the signal to select the optimum one of both means 71 and 72 in the timing preceding the stage 5 and based on the data undergone no digit matching. Then a normalizing action is carried out at the normalization stage in accordance with the instruction of the signal produced by the means 1. In such a way, the disturbance of pipeline processing can be avoided.

Title: Electronic device
Inventor: FUJIMOTO YOSHIHIRO
IPC: H05K7/20
Filed: 1989-01-12
Abstract: PURPOSE:To obtain a uniform heat distribution without loss of heat sink effect of a heat sink plate by opening an opening hole of a diameter of thickness or loss of the heat sink plate for dissipating the heat of an electronic component for generating heat. CONSTITUTION:The radius of a substantially regularly circular opening hole 6 formed at a heat sink plate 2 is the size or less of the thickness of the heat sink plate, and one or more holes are opened in the vicinity (laterally or at the top) of an electronic component for generating a heat. Accordingly, the heat of the electronic component 1 for generating heat is thermally conducted via the heat sink plate 1 so that the inner part (c) of a U-shaped inner part becomes hot, but an air flow (d) is formed in the opening hole 6 opened at the heat sink plate 2 so that it is not so hot. Since the radius of the opening hole 6 is the thickness or less of the heat sink plate, the surface area of the heat sink plate 2 is reduced as compared with the state having no opening hole 6. Thus, uniform heat distribution can be formed.

Title: Control method for transversal type equalizer
Inventor: HANEDA SADAYOSHI
IPC: H03H15/00
Filed: 1989-01-17
Abstract: PURPOSE:To prevent a synchronizing step-out from occurring even when a modulating wave is inputted again in a nonmodulation state by providing a demodulating pulse break detector which outputs a control OFF signal in the nonmodulation signal in a demodulator, outputting the control OFF signal to a waveform equalizer control part, and stopping control. CONSTITUTION:The transversal type equalizer TRSV.EQL 10 calculates the correlation between the regenerated data signal of the demodulator DEM 12 and an error signal and controls the in-phase component and orthogonal component in the TRSV.EQL 10 to equalize distortion generated on a propagation line. Then when a nonmodulation wave input state is entered, the demodulating pulse break detector 11 of the DEM 12 detects a demodulating pulse break and sends out a control OFF signal to the waveform equalizer control part 9 of the TRSV.EQL 10. Consequently, the control part 9 stops the control of the waveform equalizer 1 to maintain a last state. Consequently, when the modulating wave is inputted again to the TRSV.EQL 10, no excessive distortion is applied, so the synchronizing step-out of the DEM 12 is eliminated.

Title: High-speed processor
Inventor: ETO MASAYUKI
IPC: G06F12/08
Filed: 1994-01-25
Abstract: PURPOSE:To reduce processing time for read access to a low speed I/0 device and a memory by installing a buffer circuit for looking-ahead read data and making the buffer circuit operate by a proper program. CONSTITUTION:At the time of receiving an instruction including the address of necessary data, a look-ahead control circuit 3a immediately fetches data into a look-ahead dedicated buffer 2. A bus master executes another processing and when data becomes necessary, executes normal read instruction. At the time of receiving the read instruction, the look-ahead control circuit 3a starts a normal read cycle and compares the object address with an address stored in the look-ahead control circuit 3a to stop the normal read cycle when they are equal to deliver data from the look-ahead dedicated buffer 2 to the bus master. Thereby, when the bus master reads data from the low speed device, the processing is not interrupted by the insertion of wait, so that processing speed is improved.
