Title: Rotor of screw pump
Inventor: TAJIMA KATSUNORI
IPC: F04C15/00
Filed: 1991-12-27
Abstract: PURPOSE:To prevent a pin hole from being expanded even if a light material with low strength is used for a rotor body by making a frictional force at the discharge side larger than that at the suction side between the rotor body and shaft and providing a fixing pin nearly in the center of the whole frictional force. CONSTITUTION:Steel shafts 7, 8 are press fitted respectively into center holes of light alloy rotor bodies 5, 6 to be coupled frictionally therewith and further fixing pins 9, 10 extending diametrally through the rotor bodies 5, 6 and shafts 7, 8 are press fitted respectively into rotors 3, 4 of a screw pump. A frictional force between the rotor bodies 5, 6 and shafts 7, 8 at the discharge side of the rotor bodies 5, 6 is made larger than that at the suction side and fixing pins 9, 10 are provided approximately in the center of all frictional forces. As a result, axial frictional resistances in the axial direction of shaft fitting parts opposing to the thermal deformation of the rotor bodies 5, 6 are nearly well-balanced in the position of the fixing pins 9, 10. The axial thermal stress of the rotor bodies 5, 6 acting on the fixing pins 9, 10 planted in the shaft fitting parts is small and surface pressure acting on the pin holes 21, 22 does not exceed an allowable value.

Title: Modem for exchange line
Inventor: AKAGI YOZO
IPC: H04M11/00
Filed: 1991-12-27
Abstract: PURPOSE:To prevent its own station from being resident in the line acquisition state by detecting it when an opposite station interrupts a line due to any cause during the data communication state so as to interrupt the line of its own station. CONSTITUTION:When only an opposite station interrupts its line due to any cause during the data communication state, a telephone exchange sends a busy tone. The busy tone is inputted to the MODEM via a telephone line connection terminal 1 and a line changeover section 2 and it is detected by a busy tone detection section 8. When the busy tone detection section 8 detects the busy tone, a detection signal is outputted to a MODEM control section 7. When the busy tone is consecutive for a preset time, the MODEM control section 7 discriminates that the line of the opposite station is interrupted and outputs a line interrupt signal to the line changeover section 2. The line changeover section 2 receives the line interrupt signal to throw a moving contact 2a to the position of a fixed contact 2c. Thus, the line of its own station is interrupted.

IPC: B62H3/00
Filed: 1998-10-30
Abstract: PROBLEM TO BE SOLVED: To simplify a bicycle parking facility, and to prevent a theft by fixing only a bicycle pedal by a pedal fixing device fixed to a floor surface. SOLUTION: A pedal fixing device is opened at an angle of a certain degree by the action of a support 1, a cover 2 and a coil spring shaft 13 by fixing the support 1 to the ground surface 15 by an anchor bolt 14. A wheel fastening lock 4 for a bicycle is installed on the tip of the cover 2. A pedal 8 of the bicycle is positioned between the support 1 and the cover 2 so that a pedal shaft 10 of the pedal 8 is fitted to a recess 3 of the cover 2, and the cover 2 is put on the pedal 8 to be fitted to the support 1 to be operated so that the lock 4 is fastened. Thus, an acting metal fitting 6 of the lock 4 enters a hole of a plate 7 of a plate-like projection existing on the end of the support 1, and the cover 2 becomes unopenable, so that the pedal 8 is shut up inside. When a key 5 of the lock is pulled out, the prevention of a theft is completed.  Since this device is the size of a degree for covering the pedal of the bicycle, a facility of a bicycle parking device is not difficult, so that a place can be selected in a wide visual field.
