Title: Optical receiver
Inventor: OIMURA KATSUHIKO
IPC: H04B17/00
Filed: 1986-05-26
Abstract: PURPOSE:To obtain an optical receiver detecting the generation of an abnormal signal at the transient state caused in quickly attaching/detaching an optical transmission line by counting a pulse signal outputted from a photodetector and outputting a detection signal when the count reaches a predetermined value. CONSTITUTION:A photo diode 1 as a photodetector is connected to an optical fiber by an optical connector. The photodetector 1 converts an optical signal sent through the optical fiber into an electric signal, which is fed to an amplifier 2, which amplifies the signal and supplies the result to a comparator circuit 3. The comparator circuit 3 compares the output of the amplifier 2 with a predetermined threshold voltage to apply the threshold discrimination. In attaching/detaching an optical transmission line, the pulse signal outputted from the photodetector 1 is counted and when the count reaches a predetermined value, an attaching/detaching detection means 7 outputs a detection signal. Thus, the attachment/detachment of the optical coupling is momentarily sensed and the occurrence of an accident resulting in injury or death due to malfunction is evaded.

Title: Automatic arc welding method
Inventor: NOHARA KAZUHIRO
IPC: B23K9/028
Filed: 1990-05-12
Abstract: PURPOSE:To automatically decide welding conditions of automatic arc welding and to obtain satisfactory weld without defects by measuring the distance between a corner part of long size metal having circulararcuate corner parts and a square cross section and a pedestal. CONSTITUTION:Square barrel-shaped steel 1 is placed on a V block and moved to automatic arc welding equipment. On the way of reach the welding equipment, the steel 1 passes the inside of a height measuring instrument consisting of a laser beam transmitter and a laser beam receiver. Here, the distance (h) from the base of the V block 3 to the corner part 11 of the square barrel-shaped steel 1 is measured and the radius R of curvature of the corner part 11 to be welded is estimated from this result. The gap between the corner part 11 of the square barrel-shaped die steel 1 and a steel plate 2 is calculated from this radius R of curvature and the welding conditions are determined. When the square barrel-shaped die steel 1 reaches the welding equipment, a welding robot automatically performs automatic arc welding on the corner part 11 of the square barrel-shaped steel 1 and the steel plate 2 under the welding conditions which are already instructed.

Title: Automatic water extractor for oil cleaner
Inventor: KOUNO TSUTOMU
IPC: B01D17/12
Filed: 1978-10-05
Abstract: PURPOSE: To continuously and stably discharge the water content separated from oil in an oil cleaner by constiting the captioned oil extractor with a hermetic vessel, communicating the inside of the hermetic vessel and that of the oil cleaner through a balance pipe and connecting a U-seal piping to the hermetic vessel.  
     CONSTITUTION: During operation of an oil cleaner 2, a solenoid valve 31 is opened by the oil circulating pump run signal and normal run detection signal. On the other hand, when the cleaner 2 stops or turbine lubricating oil becomes low in temperature, the valve 31 is closed by the oil circulating pump stop signal and the output signal of a temperature switch 33. While an automatic water extractor stop valve 16 and valve 31 are open, the inside of the cleaner is put under negative pressure by running of a vent fan 17 mounted to the cleaner 2 but the inside of the cleaner and the inside of the water extractor 9 are communicated by a balance pipe 36 and therefore the inside of the water extractor 9 also becomes the same pressure as that in the cleaner and the water level of a slide nipple 15 will not lower. Here, a U-seal pipe 35 prevents the entry of the atmospheric air into the water extractor 9 owing to movement of the water contained therein. Hence, the water level of the nipple 15 is not affected by the negative pressure of the fan 17 and said water level may be maintained constant.

IPC: H01L21/208
Filed: 1991-04-25
Abstract: PURPOSE:To obtain a compd. semiconductor single crystal while controlling the shape of the pulled up crystal with high precision and good reproducibility by preparing a physical model with the lumped constant approximating that of the pulling up process and estimating a heater temp. pattern from the model. CONSTITUTION:When a compd. semiconductor single crystal is grown by the liq. encapsulation Czochralski method, the weight of the solidified compd. semiconductor is detected. The output of a heater is then controlled to a preset value from the weight. The heat energy balance at the solid-liq. interface in single crystal growth is estimated by using a physical model with the lumped constant approximating that of the pulling up process in this method, and the output of a heating element is controlled. The error in setting the temp. conditions on the actual grown crystal is minimized by this method regardless of the growth conditions such as the diameter and length of the crystal, device, etc. Besides, the heater temp. pattern is immediately determined from about one growth datum, which has been determined from many growth data, when the crystal growth condition is changed.

Filed: 1988-05-19
Abstract: PURPOSE:To improve the traveling stability of a magnetic tape by making the upper half and/or the lower half of a cassette of polystyrene resin, and simultaneously, making the moisture content of the upper half and/or the lower half to be over prescribed ppm. CONSTITUTION:One of the upper half 1 and the lower half 3 can be made of polystyrene resin, or both the upper half 1 and the lower half 3 can be made of polystyrene resin. Then, the moisture content of the upper half 1 and/or the lower half 3 is made over 240ppm when it is measured by a measuring method using, for instance, a Karl Fischer's measuring instrument.

Title: Gear change control device for sub-transmission
Inventor: OKAHARA HIROBUMI
IPC: F16H63/44
Filed: 1989-05-18
Abstract: PURPOSE:To eliminate the delay of engine brake operation by so providing a bypass circuit opening in an engine brake range or a backward travel range as to be in parallel to an orifice for limiting the fluid oil pressure rise rate of a low-speed select friction element. CONSTITUTION:In shifting a sub-transmission via the coupling of a low-speed select friction element RD/B so provided as to be in parallel to a one-way clutch, the coupling pressure is gradually raised for normal drive and quickly raised for reverse drive or reverse rotation output via the interruption and continuity of a bypass valve 163 with a reduction timing valve 66. In the ordinary drive, therefore, the RD/B is coupled without any shock after releasing a high-speed select friction element D/C and then the engagement of the one-way clutch. On the other hand, during the reverse drive (engine brake) or reverse rotation output (backward travel), the operation of RD/B is synchronized with the releasing of D/C and quickly coupled. According to the aforesaid construction, a delay in the effectiveness of the engine brake can be prevented.
