Title: Detecting method of slip and sliding of railway rolling stock
Inventor: MORIIZUMI JITSUO
IPC: B60L3/10
Filed: 1995-01-27
Abstract: PURPOSE: To utilize the detecting method of the slip and sliding of a railway rolling stock for controlling subsequent adjustable speed by measuring acoustic waves by means of an acoustic emission sensor through a wheel, an axle and a journal box when slip or sliding occurs and detecting the occurrence of the slip or sliding of the wheel by the difference of obtained frequency and sound pressure level thereof. CONSTITUTION: The sound pressure level 1 of an acoustic emission sensor (an AC sensor) during the stoppage of a car is lower than that 2 when a train travels without slip or sliding. When slip occurs, the sound pressure level 3 of the AE sensor is increased because a wheel accompanies self-excited vibrations. That is, when the normal state 2 is determined previously, slip can be detected easily by the magnitude of the sound pressure level of the AE sensor generated during acceleration from the car. Accordingly, when slip and sliding are controlled surely, the adjustable speed of a railway rolling stock can be made larger than conventional railway rolling stocks.

Title: Circular toothed gear
Inventor: TANAKA NAOYUKI
IPC: F16H55/08
Filed: 1983-01-28
Abstract: PURPOSE:To reduce noise and increase strength by foring tooth form to mountain shape and forming the torsion angle of tooth frace to a specific angle or more, in a circular toothed gear in which the tooth form on the plane perpendicular to axis or the section perpendicular to the tooth is circular form. CONSTITUTION:Since the length of simultaneous contact line does not vary on the tooth surface of a circular toothed gear, the amount of transfer of the center of load weight accompanied by the advance of engagement increases, and the variation of the bearing repulsive force increases. In order to solve this problem, the circular tooth shape is formed into mountain shape to form a double-helical gear. Therefore, each transfer direction of the center of load weight of the right and left double-helical gears becomes opposite each other, and the amount of transfer of the center of load weight of the whole double-helical gear can be reduced to zero theoretically, and noise can be reduced by a large margin. The tooth trace of the circular toothed gear and the number of simultaneous contact areas increase in proportion to the sine sin beta of torsion angle, when module (m) and face width (b) are constant. At the position where the torsion angle beta is large than 30 deg., an optimum value exists with which the load DELTAWn in the direction perpendicular to the tooth trace per contact point in accordance with the ratio of module to face width is reduced to the min.

IPC: C21C7/10
Filed: 1989-01-23
Abstract: PURPOSE:To prevent the deposition of a splash in a vacuum vessel by supplying a gaseous mixture while increasing the ratio of a nonoxidizing dilution gas to oxygen in the progress of decarburization.

Title: Film unit with lens
Inventor: KAMATA KAZUO
IPC: G03C3/00
Filed: 1996-01-26
Abstract: PROBLEM TO BE SOLVED: To prevent the unauthorized refill of photographic film. SOLUTION: Every time photographing is performed, a synchro switch 53 is turned on and an on-signal generation circuit TO generates an on-signal. Every time the on-signal is inputted, a microcomputer 60 updates a counted value Kc written in an EEPROM 72 and counts the number of already exposed frames. When a charging switch 55 is turned on, the microcomputer 60 compares the counted value Kc in the EEPROM 72 with the number of frames to be exposed stored in a ROM 60b. In the case the former is smaller than the latter, the microcomputer 60 transmits a charging start pulse to a charge and light emission part 71 so as to charge a main capacitor.  In the case the former coincides with the latter or the former is larger than the latter, the microcomputer 60 judges that the photographic film housed in its manufacturing process has been already used up, and does not transmit the charging start pulse even when the switch 55 is turned on, so that the main capacitor is not charged. Therefore, it is impossible to use the film unit with a lens in the case the unauthorized refill of the photographic film is done.
