Abstract: PROBLEM TO BE SOLVED: To provide the generation method of duo binary signals modulatable by binary electric signals and an optical transmitter. SOLUTION: A semiconductor laser 1, a light intensity modulator 2 and a optical phase modulator 3 are cascade-connected. Data signals 6 are branched into two, one is inputted to the light intensity modulator 2 and signal light 4 outputted from the semiconductor laser 1 is intensity-modulated. The other data signal of the ones branched into two is inputted to a precoder 7. The precoder 7 performs code conversion by the logic that output is inverted from '0' to '1' or '1' to '0' when the inputted data signal 6 is '0' and the output is not changed when the inputted data signal 6 is '1'. After the output of the precoder 7 is delayed for 0.5 bit, the intensity-modulated signal light 4 is phase- modulated.  The signal light 4 to which both modulation of the intensity modulation and phase modulation is performed is provided with the feature of light duo binary signal light that 'a phase is inverted at the intermediate point of one time slot when the amplitude of the light is '0''.

Title: Metal plate bending method and bending machine
Inventor: KOYAMA KATSUMI
IPC: B21D5/02
Filed: 1996-01-12
Abstract: PROBLEM TO BE SOLVED: To prevent a metal plate from displacing and to accurately bend it at the time of re-bending after measuring the bending angle. SOLUTION: In a time of separating a punch P and a die D, and generating a spring back, because the pressing force is energized to the mutual approaching direction, the metal plate W is made always in a state of being clamped with the punch P and the die D. Therefore, because the positional relation of the punch P and the die D against the metal plate W is kept definitely in the case of re-bending after correcting the D-value from the result of the angle measurement, the displacement of the bending position can be prevented. For example, in the case of the die D being energized to the punch P side with an elastic member 17, even in the case of separating the punch P and the die D, the metal plate W is clamped with the punch P and the die D. Further, the punch P is made enough being hung with the elastic member.  Further, the punch P is made enough freely attachable and detachable or freely moving up and down by a prescribed amount.

Title: Back projection screen
Inventor: TOSAKA MASATOSHI
IPC: G03B21/62
Filed: 1990-01-12
Abstract: PURPOSE:To reduce the loss of a light beam by combining materials which differ in refractive index so that a low refractive index is obtained on a light source side and a high refractive index is obtained on an observation side and forming a lenticular lens on the observation side. CONSTITUTION:The reflection factor is smaller and smaller and the transmissivity is larger and larger on a border surface 3 between two media as the refractive index difference between the media is smaller and smaller. For the purpose, the light source side where a light beam is made incident is made of a material having a low refractive index and the observation side, i.e., the lenticular lens surface 2 is made of a material which has a high refractive index. Consequently, the ratio of a light beam which is reflected by the entire border surface even including the reflective index of the border surface 3 between the low-refractive-index material and highrefractive-index material and the reflection factor on the incidence surface 1 is smaller than the reflection factor when the light is made incident directly on the high-refractive-index material, so that the loss of the light beam is reduced.

Title: Recovering method of valuable metal from manganese nodule
Inventor: IMAIZUMI YUJI
IPC: C22B5/02
Filed: 1996-01-16
Abstract: PROBLEM TO BE SOLVED: To obtain a valuable metal capable of being utilized as a refining raw material as it is by pulverizing and floating a slag phase separated from a mat phase in the recovery of the valuable metal from a manganese nodule. SOLUTION: The manganese nodule is melted and reduced to be separated into Fe, Mn, Ni, Co and Cu as a metallic phase and a manganese oxide as a slag phase. The mat phase is formed by adding a sulfiding agent to the metallic phase to covert the metal to the sulfide. Next, Fe and Mn in the mat phase is preferentially oxidized to be transferred to the slag phase by adding a flux to the phase and oxidizing. Ni, Co and Cu are recovered by leaching from the mat upgraded in Ni, Co and Cu with an acid In the process, the slag separated from the mat phase is pulverized and the pulverized material is floated to recover the valuable metallic sulfide. As a result, Ni, Co and Cu are recovered from the slag at high yield without necessitating a large scale device.

Abstract: PURPOSE:To prevent smoked roof tiles from causing defects such as sooting, peeling or the like, thus increase the yield of the roof tiles, by using, as a deposition gas, a high-temperature, non-oxidizing, dilute gas, generated from a separately installed dry distillation apparatus. CONSTITUTION:Tile bodies are baked in the oven 1 with burner 3 in an oxidative atmosphere, then the opening of the oven 1 (for example, the valve 12 for exhaustion duct 11) is tightly closed. Then, the materials to be drydistilled (fed from the hopper 6) is dry-distilled in the separated installed dry distillation apparatus 4 in a non-oxidizing atmosphere (generated from the burner 5) and the dry-distillation gas is diluted with the above-stated high-temperature non- oxidizing gas. The diluted gas is used as a deposition gas, as it is maintained at an elevated temperature of 900-1,000 deg.C, to feed from nozzle 10 into the oven 1, as the oven 1 is kept at a positive pressure. This deposition process deposits the carbon in the gas on the baked tile surfaces and crystallizes the carbon into graphite by phase transition.
