Title: Method for inspecting pulse body current
Inventor: SAKAMOTO TAKAHIDE
IPC: G01N27/90
Filed: 1985-09-25
Abstract: PURPOSE:To obtain good quality detection output reduced in wave-form distortion, by storing the output of a detection coil at a flawless time and taking the differential voltage between memory output and the output of a detection coil at the time of actual inspection to amplify the same. CONSTITUTION:In a flawless state, switches 42, 44 are closed to an '1' side and a memory order switch 40 is closed. Subsequently, the differential output of detection coils 14, 16 is applied to an A/D converter 26 which in turn samples differential voltage at every clock input of 1,024kHz to write the same in a memory 28. After the storing of the differential voltage in the memory 28 was finished, the switches 42, 44 are changed over to a '2' side to perform the inspection of an actual object to be inspected. The differential voltage of the coils 14, 16 is applied to one input terminal to a differential amplifier 38 and the output voltage of a D/C converteer 30 read from the memory 28 is applied to the other input terminal of the amplifier 38 to calculates the difference between both of them. This difference is almost zero if the object 10 to be inspected is flawless and, if there is a flaw, comes to differential voltage determined by said flaw and S/N is enhanced to a large extent and good amplification can be performed and good quality detection output free from wave-form distortion is obtained.

Title: Exhausting/collecting device with oil rotation pump using fluorinated type oil
Inventor: OKUTOMI SHOJI
IPC: F04B37/14
Filed: 1990-08-10
Abstract: PURPOSE:To collect exhaust gas without releasing to the atmosphere by using fluorinated type oil, which has a large specific gravity and is inert for exhaust gas such as t-butyl-alcohol, as the oil for an oil rotation pump, separating the exhaust gas according to the difference in the specific gravity from the fluorinated type oil, and thereupon dissolving it in water. CONSTITUTION:The suction hole of an oil rotation pump 10 is connected with a vacuum trough 20 via a suction pipe 22, and an organism specimen 21 to be frozen and dried is accommodated in the vacuum trough 20. Via the exhaust pipe 31, a water tank 30 is connected with the gas exhaust hole of this oil rotation pump 10, which is filled with a fluorinated type oil 11 to the exhaust pipe 31 side. The water contained in the organism specimen 21 is substituted with a component, for example t-butyl-alcohol. To dry the specimen 21, evacuation is made by the oil rotation pump 10 via the suction pipe 22. Now the sublimated t-butyl-alcohol gas is taken in via the suction pipe 22 into the fluorinated type oil 11 in the oil rotation pump 10. Thereby the t-butyl-alcohol can be collected together with water 32 without releasing to the atmosphere.

Title: Optical transmitter
Inventor: MIYAMOTO YUTAKA
IPC: H04B10/2537
Filed: 1999-07-27
Abstract: PROBLEM TO BE SOLVED: To prevent a case where the inter-code interference is easily caused on an optical fiber transmission line and at an optical transmitting/receiving part by modulating the intensity of continuous beams so as to make the phases of optical modulation signals corresponding to the 1st and 3rd levels of a differential signal be different from each other by π. SOLUTION: The precoding circuits 1 and 1' output the value of an exclusive OR between the NRZ(non-return-to-zero) differential signals inputted from the input terminals 14 and 14' and the signals obtained by delaying by one bit the value and the code value of the NRZ differential signals. The band pass filters 2 and 2' serving as the differential coding means generate the differential electric signal pulses of different polarities at the rise and fall points of the said exclusive OR value.  Then a light intensity modulator 4 serving as a light intensity modulating means returns a differential electric pulse waveform around the 2nd level of a ternary differential electric signal in response to the differential electric signal pulses and also modulates the intensity of continuous beams so as to make the optical modulation signals corresponding to the 1st and 3rd levels of the differential signal be different from each other by π.

IPC: H01L21/60
Filed: 1995-07-19
Abstract: PROBLEM TO BE SOLVED: To prevent the generation of heat dissipation in the middle between the inflow of gas and the exhaust of the gas by a method wherein a hot blow heater, which is provided with a metal protecting tube which heats and discharges the gas sent from a high-pressure gas cylinder, a blower or the like, and a box, which has an aperture of an external shape roughly equal with that of a BGA in its bottom and has an exhaust vent in its upper part or side surfaces, are connected directly with each other. SOLUTION: N2 gas sent from a high-pressure gas cylinder, such as an N2 gas cylinder, goes through a hose 1 and a gas inflow vent 2 and comes into contact to a heater 5, whereby the gas is heated up and the heated-up gas flows in a metallic box 20, heats a BGA 30 and is exhausted through an exhaust vent 22. At this time, the temperature of a thermocouple temperature measuring part 4 is measured by a temperature regulating meter 50 via a thermocouple lead wire 3 and moreover, the output of the heater 5 is controlled and a heater discharge gas temperature can be controlled. By using a metal protecting tube 8, the box 20 and an upper heated air heater 10 can be connected directly with each other. Thereby, the distance between the heater 10 and the box 20, which corresponds to a furnace for heating the BGA 30, is shortest as seen in a distance manner and wastage of heat is eliminated.

The laser gas, which is ionized by the discharge at the most upstream side, is made to flow toward the downstream. Thus the discharge at the downstream side is made easy. Therefore, the discharge state is stabilized, and the stability of the laser output becomes excellent.
