Title: Subbase course material and its production
Inventor: TAKAHASHI TATSUTO
IPC: C04B5/06
Filed: 1997-06-30
Abstract: PROBLEM TO BE SOLVED: To obtain a subbase course material capable of being produced even from powdered slag and free from the generation of disintegration, powdering due to free CaO and problems due to the elution of Ca(OH)2 or the like. SOLUTION: A subbase course material uses granular and/or coarse particulate slag as a main row material and CaCO3 or CaCO3 and MgCO3 (where, including the case that MgCO3 exists as a hydrate, a hydroxide or a double salt) in which the slag is generated by a carbonation reaction, is solidified as a binder and agglomerated. The manufacturing method is for forming the pile of the granular and/or coarse slag or the packed layer of the same in an optional space, causing the carbonation reaction in the presence of carbon dioxide in the pile or the packed layer to solidity the slag and to make a stone material where the slag is agglomerated and the stone material is pulverized to make a prescribed subbase course material particle size.

Title: Semiconductor device
Inventor: MATSUOKA TAKASHI
IPC: H01L21/822
Filed: 1987-07-28
Abstract: PURPOSE:To form a wideband amplifying section to a shape closer to a square while reducing the area of a semiconductor chip by dispersing and arranging via holes for a transistor in the two-dimensional direction in the surface of a semiconductor substrate. CONSTITUTION:Source wirings 2a-2e for shaping a source region, drain wirings 4a-4d for forming a drain region and a gate wiring for shaping a gate region are formed onto a semiconductor substrate 1, and transistors Q1-Q8 are composed of these source, drain and gate each region section. Via holes 3a-3e are shaped at approximately the centers of the wirings 2a-2e, and the wirings 2a-2e are connected to a grounding region formed onto the rear of the substrate 1. Since the holes 3a-3e are disposed zigzag at that time, the length of the source region in the direction of arrangement of the transistors Q1-Q8 can be shortened, thus shortening the length of a wideband amplifying section in the direction of arrangement of the transistors Q1-Q8.

Abstract: PURPOSE:To improve the system bus access processing of a CPU and the processing of an input/output controller by allowing a CPU to access a system bus after DMA access if the system bus access request of the CPU and the DMA request of the system bus overlap each other. CONSTITUTION:A bus controller 30 sends A DMA access request signal to the CPU 10 so as to attain DMA access to a storage device 20 and the CPU 10 receives it and sends a DMA access permission signal to the controller 30. Where, when the access signal from the CPU 10 to the system bus 50 and the DMA access request signal from the controller 30 overlap each other, the controller 30 releases a processor bus 40 forcibly to the CPU 10, masks all responses from the device 20, and sends out a forcible DMA execution signal 120 to the CPU 10 so as to accept the DMA access request signal from the controller 30 preferentially. Then the controller 30 starts the DMA access to the device 20. Then the CPU 10 access the system bus 50 after the DMA access is completed.

Title: Surge voltage suppressor
Inventor: MATSUSHITA KUNIO
IPC: H02H9/04
Filed: 1997-07-16
Abstract: PROBLEM TO BE SOLVED: To reduce the size and the cost of a surge voltage suppressor. SOLUTION: A surge absorber AL1 having nonlinear resistance characteristics and a thyristor TH1 are connected in series to the DC side of a three-phase high voltage rectifier circuit DB being connected to the load side (or power supply side) of a high speed semiconductor circuit breaker 1 employing a self- extinguishing element. Resistors R11, R12 sharing the voltage are connected in parallel with the AL1 and TH1 and the series circuit of a resistor R13 and a breakover diode BOD1 is connected between the anode and gate of the thyristor TH1 as the gate control circuit for the thyristor TH1. When the high speed semiconductor circuit breaker 1 functions to generate an overvoltage between the load side lines, a diode BOD 1 is broken at an arbitrary level to turn the thyristor TH1 on and the overvoltage is absorbed and suppressed by means of a surge absorber AL1.  When the DC voltage drops, the TH1 current decreases below a retaining current and the thyristor TH1 is turned off. Since the circuit employs no capacitor for absorbing the surge, the size and the cost can be reduced.
