Title: Burner
Inventor: ONO TADASHI
IPC: F23D14/24
Filed: 1988-06-06
Abstract: PURPOSE:To reduce the pressure loss as much as possible and obtain a specified swirl flow by providing a boss and guide vanes substantially concentrically with a fuel nozzle as the center in a cylindrical and bottomed combustion chamber using the fuel nozzle as a motor shaft to form a centripedal blower. CONSTITUTION:On the back face of the bottom section 2 of a combustion chamber 1 a motor 3 is fixed. One side of a hollow motor shaft of a motor 3 pierces through the bottom section 2 of the combustion chamber to form a nozzle 5 for fuel in the combustion chamber 1. Guide vanes are fixed respectively to the motor shaft 4 through a boss 6. The outer circumference of the guide vanes 7 is located in the vicinity of the side wall 8 in the combustion chamber 1 and adjacent to it substantially concentrically. The side wall 8 is provided with a section port 9. As soon as the motor starts rotating, swirl flows of air between the circle with a diameter equivalent to the boss diameter and the side wall of the combustion chamber is formed in the combustion chamber and they flow to the downstream of the combustion chamber. Simultaneously at the boss section in the center of the combustion chamber a large recirculating area is formed. From a fuel nozzle at the center of the boss fuel is jetted out to be supplied to the center of the recirculating area. As a result diffusion and mixing are carried out sufficiently near the boss and it is made possible to perform a stable and firm flame holding.

Title: Semiconductor storage device nd error correction method therefor
Inventor: NOBUKATA HIROMI
IPC: G11C29/42
Filed: 1997-05-28
Abstract: PROBLEM TO BE SOLVED: To easily and surely perform bit error correction for a multilevel memory without increasing a circuit size and a process time. SOLUTION: In this device, a parity generation and error correction circuit 5 as first and second parity generating circuits generates an error correction code, in a different manner based on whether a memory bit indicating presence of data has an even number or an odd number. A control circuits 6 outputs to the first parity generating circuit a first error detection signal indicating memory bits which are different in a predetermined order between adjacent memory cells, and to the second parity generating circuit a second error detection signal in which only one memory bit is common to the first error detection signal, and changes these error detection signals so that the common memory bit can be determined explicitly in a block.  In addition, the parity generation and error correction circuit 5 determines as an error correction circuit whether the error correction code at readout coincides with that at writing. When they do not coincide, bits for data in the memory cell corresponding to the common memory bit are inverted.

Title: Radio communication device and its method
Inventor: AIKAWA HIDETO
IPC: H04W56/00
Filed: 1998-05-20
Abstract: PROBLEM TO BE SOLVED: To avoid momentary interruption of voice or data in a communication mode by establishing synchronization between a base station under communication and its adjacent base station during transmission or non-transmission of an idle slot of a resident or non-resident carrier and receiving a hand-off command from the base station under communication to start radio communication with the adjacent base station. SOLUTION: When a mobile station 13 gets out of a zone 11a of a base station 11, the receiving level of the station 11 is detected by a resident carrier NSC of a frequency f2. When the receiving level of the station 11 is lowered than its standard level, the receiving level of an adjacent base station 12 is detected in a non- transmission state of an idle slot of the station 11. When the receiving level of the station 12 is lower than its standard level, the station 13 establishes synchronization with the station 12 and switches the communication carrier from the carrier NSC of frequency f4 of the station 12 to a non-resident carrier CC of frequency f2 of the station 11.  Then the station 13 restarts the communication with the station 11, receives a hand-off command from the station 11 and switches the communication carrier from the carrier CC of the station 11 to the carrier NSC of the station 12 to perform an hand-off operation.

Abstract: PURPOSE:To separate a linear polarized component from random polarized light by using a liquid crystal material which is birefringent as a means which converges polarized components. CONSTITUTION:The liquid crystal material which is birefringent is sandwiched in an oriented state between isotropic parts (12 and 14) formed of two optically isotropic transparent materials (with a refractive index ni).
