Title: Normal random number generator
Inventor: SATOU MASAHARU
IPC: G06F7/58
Filed: 1981-07-22
Abstract: PURPOSE:To decrease the time of operation, by writing previously the normal random number data in a memory, having the correspondence between the uniform random number produced from a multiplier and the address of the memory and reading the normal random number data out of the memory. CONSTITUTION:The initial value A is added to a multiplier 1, and the multiplication is carried out to obtain the uniform random number A'. This number A' is fed back to have the multiplication again, and the uniform random number is repetitively producd. This uniform random number produced continuously is fed to a memory control circuit 3. The circuit 3 secures the correspondence between the uniform random number and the address of a memory 2. Then the normal random number data is read out of the memory 2, and the normal random number can be produced. As a result, the normal random number can be obtained within the time of operation during which the uniform random number is produced. Thus the time of operation during which the normal random number is produced can be greatly decreased.

Title: Correlator
Inventor: MIYASHITA ATSUSHI
IPC: H03H17/02
Filed: 1981-07-22
Abstract: PURPOSE:To simplify the constitution of a control signal generating circuit for a correlator which obtains the correlation among plural digital signal groups, by forming the bit number of each shift register so as to have different numbers of bits in a circulation mode. CONSTITUTION:The total number of bits of a shift register 21a forming at least a circulating shift loop is made different from that of a shift register 21b forming another circulating shift loop. At the same time, the circulating shift pulses CLK of the same prescribed number of bits are applied to the registers 21a and 21b to perform a process. In such way, the constitution is greatly simplified for a control signal generating circuit.

Title: End part displacement reducing device for pontoon type buoyant body structure
Inventor: MITAMA ICHIRO
IPC: B63B39/00
Filed: 1999-03-18
Abstract: PROBLEM TO BE SOLVED: To high reducing effect of end part displacement by force-feeding gas by a blower into an area partitioned by specific partition walls around the bottom face of a structure, to form a gas layer, and providing a gas chamber communicating with the partition area, to ensure gas capacity. SOLUTION: Partition walls 2 are mounted double over the whole periphery of the bottom face of a buoyant body structure 1 to constitute a partition area around the bottom face of the buoyant body structure 1. A gas chamber 3 is provided over the whole peripheries of the buoyant structure body 1 and the partition area around the bottom face of the buoyant body structure 1. Gas can be force-fed into the partition area around the bottom face by driving a blower 4 to form a gas layer 7 in the partition area. At this time, the gas is force-fed into the partition area after retaining high pressure gas in the gas chamber 3. Since the gas chamber 3 is provided communicating with the gas layer 7, gas capacity for receiving force caused by waves can be enlarged. Cushioning effect is therefore heightened to increase the displacement reducing degree.
