Title: Oval flowmeter
Inventor: YAMAMOTO HIROSHI
IPC: G01F3/10
Filed: 1983-05-09
Abstract: PURPOSE:To improve measuring accuracy, by forming the major axis part of an oval gear by a porous plate, such as a honeycomb plate and a metal foam body, providing a porous plate also in both side walls of the gear, thereby providing a labyrinth effect, and reducing the amount of leakage from the gap between the gear and the inner wall of a measuring chamber. CONSTITUTION:A part of the tooth at the major axis part of an oval gear, which is indicated by a hatched part in the Figure and a part of the tooth at the minor axis part, which is intermeshed with said tooth, are cut out. At the cut- out major axis part, a porous plate 30 such as a honeycomb plate, a metal foam body, or resin foam body is provided. In this constitution, a labyrinth effect acts between the major axis part of the oval gear and the inner wall surface of a measuring chamber, and the amount of leakage is reduced. The tooth 10a at the major axis part is cut out with a central part 10' being remained. Conversely, the central part can be cut out and both end parts are made to remain. A porous plate 30' such as the honeycomb plate and the metal foam body described above, which has the labyrinth effect, can be provided on both side surfaces of the gear.

IPC: B23K20/00
Filed: 1987-03-31
Abstract: PURPOSE:To improve yield even of a complicated shape product by manufacturing each part composing a toothed wheel, diffision-joining after assembling each part and thereafter subjecting to refining treatment. CONSTITUTION:Each part of the rim part 3, a plate part 4 and boss part 5, etc., composing a tooth wheel is prepd. by rolling the cut billet 2 after cutting a billet 1 in the necessary dimension.

Title: Optical switch
Inventor: KOMOTO KATSUTOSHI
IPC: G02B26/08
Filed: 1996-03-08
Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of oil leakage during long-term use and the contamination of a case and the parts near the same by keeping the pressure of the oil in the case lower than the atm. pressure outside the case. SOLUTION: Gas 28 (dry air or gaseous nitrogen, etc.) is put into the upper part in the case 10 without completely filling up the inside of the case with the oil 24. For example, the pressure of the gas 28 is equal to the atm. pressure outside the case 10 in the state right after hermetic sealing of the case 10. The gas is, thereupon, partly sucked by connecting a suction device to a nipple 30. Consequently, the pressure of the oil 24 drops. The suction is stopped and the nipple 30 is sealed, when the pressure of the oil 24 near at least an oil seal 26 drops below the pressure outside the case 10. If the pressure of the oil 24 is lower than the pressure outside the case 10, the oil 24 does not leak to the outer side of the case 10 even if the function of the oil seal 26 is insufficient.

Filed: 1989-04-03
Abstract: PURPOSE:To recognize the degree of allowance of the operation of error detection in lapse of time in an identification reproduction circuit by superimposing a low frequency pulse with variable amplitude generated by frequency-dividing the output waveform of a timing circuit on the output waveform of an equalizing amplifier circuit, and checking mutual relation between the amplitude value of the low frequence pulse and an error rate. CONSTITUTION:When the operating state of the identification reproduction circuit 5 is detected, a supervisory controller 8 receiving a control command sets the amplitude of the low frequency pulse at a prescribed value by controlling an amplitude control circuit 10, and also, superimposes the low frequency pulse on an equalizing amplifier signal by turning on a switch 11. The equalizing amplifier signal on which the low frequency pulse is superimposed is identified and reproduced at the identification reproduction circuit 5. When the identification reproduction circuit 5 is operated normally, the error rate is increased, and when the identification reproduction circuit 5 is operated abnormally, the error rate is decreased. Therefore, the degree of allowance of the operation in the lapse of time of the identification reproduction circuit can be detected.
