Title: Apparatus for biochemical disposal of filthy water
Inventor: KAWADA TEIJI
IPC: C02F3/12
Filed: 1982-08-31
Abstract: PURPOSE:To alleviate reliance on a conventional heating means, by surrounding an aeration tank buried underground with a pipe having one end opened to the atmosphere, and connecting a blower to the other end. CONSTITUTION:Filthy water 14 is reserved in an aeration tank 12 provided in the ground 13 and subjected to aerobic biotreatment. Said aeration tank 12 is surrounded with a pipe 20 buried underground and having one end opened to the atmosphere, and a blower is connected to the other end of the pipe 20. By the operation of said blower, hot air in the daytime is sent into the pipe 20 buried underground and circulated therethrough. Hence, heat retained in the hot air can be supplied to the aeration tank or the ground 13 surrounding the aeration tank and accumulated therein. Thus, the filthy water in the aeration tank can be heated or kept warm in winter or during the night.

IPC: H01J37/21
Filed: 1978-12-06
Abstract: PURPOSE: To compensate the astigmatism of electron beam and to focus by scanning essentially circularly a sample with a pre-determined pattern, detecting the waveform of the information signal and using the waveform.  
     CONSTITUTION: The electron beam 2 passed through the condenser lens 1 and iris 4 of an electron beam scanning device is scanned on a standard sample surface 10 with a pre-determined pattern, informations characterizing the pattern are detected with the detector 5 and introduced to the monitor 9, and signal waveform is observed. If the electron beam operates with astigmatism the width of the signal waveform varies, the astigmatism compensating coil 3 will be controlled, and if the electron beam is out of focus the shape of signal waveform varies, the condenser lens 1 will be controlled. Thus the astigmatism compensation and the focusing can be made easily and accurately without any experience and skill of a man.

Title: Automatic run-out preventive device for furnace
Inventor: NAGANO KAZUSHIGE
IPC: F27D21/00
Filed: 1988-06-17
Abstract: PURPOSE:To prevent accidental run-out by automatically blowing compressed air to forcibly cool the furnace shell when a abnormal overheating of the furnace shell is detected. CONSTITUTION:When there is an anomaly such as bumping of molten metal to such an extent that the temperature of the furnace shell surface with which a fuse element 24 is in contact exceeds the melting point of the fuse element 24, the melting of the fuse element 24 starts from its contact point with the furnace shell. The drops 24a of melted fuse element 24 drips down, and ultimately the compression spring 23 cannot support the weight. The remainder of fuse element 243, compression spring 23, holder 22, plug 21 and packing 20 all drop down to cause the nozzles 10a to eject compressed air to forcibly cool the furnace shell 1. As a result, the interior of the furnace is gradually cooled down and the bumping of molten metal ceases, preventing accidentally run-out to the outside of the furnace. The ejection of compressed air can be monitored by a flow switch 13 to indicator or record the occurrence of the anomaly.

Title: Wire bonding device
Inventor: IWATA MASANARI

Filed: 1983-08-19
Abstract: PURPOSE:To smoothen the movement of an arm and then contrive the reduction of the failure rate by a method wherein the contact of metals with each other is eliminated by insertion of a spacer made of fluorine resin between the arm and a pin. CONSTITUTION:The spacer 13 of fluorine resin is inserted to the bonding arm 1 so that the pin 6 does not come to direct contact with the metallic section of the arm 1. Since fluorine resin has a low coefficient of friction (low coefficient of friction also with metal) and is excellent in wearing resistance, the frictional force imposed on the arm 1 from the pin 6 becomes markedly small, and the variation of frictional force with times becomes equal to nothing. Here, the spacer of fluorine resin is arranged in the arm 1; however, a ring made of similar resin can be also provided on the pin 6 side.
