Title: Data transfer circuit
Inventor: YAMANE SHINGO
IPC: G06F13/38
Filed: 1982-05-13
Abstract: PURPOSE:To prevent the occurrence of an error, by detecting the source voltage of a device when data in a memory is transferred from the 1st processor to the 2nd processor, and inhibiting the data transfer if the detected voltage is less than a threshold value. CONSTITUTION:Transfer data D is transferred from the memory 5 of the 1st processor 1 to the memory of the 2nd processor 2 through a data line 3 while controlled by a write signal S6. The voltage Va at a terminal A is detected by a detector 10 and when it is less than a rated value, a write inhibiting signal S4 is generated and inverted by a TR11 into a signal S5, which is pulled up by a resistance 12, so that an AND circuit 13 inhibits the transfer of a write signal S3 to an input memory 7 when the level of the inverted signal S5 is L. Consequently, malfunction which occurs when the source voltage is less than the rated value is prevented.

Title: Auxiliary light source in wavelength division multiplex
Inventor: GOTO RYOSUKE
IPC: H04B10/079
Filed: 1999-03-25
Abstract: PROBLEM TO BE SOLVED: To provide an auxiliary light source in wavelength division multiplex for covering many channels with fewer auxiliary light sources at a low cost by combining existing parts without using new devices, and making a restoring time short. SOLUTION: An optical pulse with four or longer wavelengths at intervals of equal wavelength to each other is generated from a WDM light source by using outer modulators EM1 to EM4. When a defective light source is detected, the remaining wavelengths of the normal light sources are combined to generate a four light-wave mixed light beam, that includes the wavelength of the defective light source. The output light equal to the wavelength of the defective light source is extracted from the four light-wave mixed light beam, and the output light is subjected to injection mode locking through a multiple- longitudinal mode oscillation laser to cause the light beam to oscillate in a single mode.

Title: Power generating system
Inventor: IRIE SHIGEO
IPC: F03B13/00
Filed: 1999-02-17
Abstract: PROBLEM TO BE SOLVED: To generate power effectively utilizing water energy with a good efficiency by carrying hydrogen to a high position by a pipe, supplying hydrogen to a fuel battery, reacting hydrogen with oxygen to generate power, and making water generated at this time fall down to generate power. SOLUTION: Hydrogen and oxygen generated between a plurality of electric poles 2, 3 disposed in a water solution tank 1, are supplied to a fuel battery 6 which exists at a high place by a plurality of pipes 4, 5, and they are reacted with each other to generate power. Water generated in this time is supplied to a power generator 8 which exists at a low place bypassing a water feed pipe 7 to generate power. Falling water is returned to a water solution tank again. Since the hydrogen and oxygen are raised in the pipes 4, 5, they are simply supplied to the fuel battery 6. Since head drop is an important element in a hydraulic turbine power generation, power is generated by arranging the fuel battery on the roof of a high-rise building, thereby making it possible to ensure large power generation capacity utilizing a large head drop.

Title: Heat treatment of metallic material
Inventor: IWATA HITOSHI
IPC: C21D1/00
Filed: 1980-06-19
Abstract: PURPOSE: To cool a metallic material at a prescribed rate of cooling by evacuating the space in the upper part of a tightly closed hot water tank, and immersing the high temp. metallic material into the hot water of the temp. close to b.p. under the pressure thereof.  
     CONSTITUTION: Hot water 3 is put into a tightly closed hot water tank 2, and is heated by a heater 8. When the space 4 in the upper part of the tank 2 is evacuated by using an evacuating device 5, the hot water 3 begins to boil at the b.p. corresponding to the temp. in the space 4. A wire material 1 is guided by a guide roller 7 in an arrow direction, is immersed continuously into the hot water 3 and is drawn out. In this case, a pipe made of refractories is used for the inlet 6 of wire material into the tank 2 because the high temp. wire material 1 passes therethrough. According to this method, the hot water 3 boils under reduced pressure, and therefore the volume of vapor increases and produces the thick and stable vapor film on the surface of the material 1, thus resulting in the decreased rate of cooling. Hence, the rate of cooling is controlled easily by regulating the degree of pressure decrease.
