Title: Vibration welding method
Inventor: SHIMIZU MINORU
IPC: B29C65/08
Filed: 1987-11-30
Abstract: PURPOSE:To prevent burrs from separating and scattering inside and outside a formed item during its use by a method wherein the burrs, which develop by welding two hollow plastic members by vibration, are fixed in a burr reservoir space. CONSTITUTION:The joining wall part 1a of a steering boot 1 and the joining end part 7d of a connector 2 are brought into close contact with each other. Welding is done by heating joining parts and at the same time vibrating (A) a second jig 5. During vibration welding is executed, burrs 8a and 8b develop at the inner and outer peripheral edges of the weld of the connector 2 and the burrs 8a remain in a burr reservoir space 7c''. The burrs 8a, which develop successively, gather in the burr reservoir space 7c'' under the state being compressed, resulting in fixing in the burr reservoir space 7c'' when they cool down and solidify. Since the burrs fix in the burr reservoir space, even when the burrs separate from the space during the use of a formed item, the burrs do not scatter inside and outside the formed item.

Title: Method for controlling meandering of belt in color printer and apparatus therefor
Inventor: IKEDA TERUYUKI
IPC: G03G15/01
Filed: 1998-10-12
Abstract: PROBLEM TO BE SOLVED: To make it possible to minimize the meandering of a belt by controlling the driving of a steering mechanism in accordance with a belt edge learning value and the data on the belt edge position at every measured microsection. SOLUTION: The average position data on the belt edge at every microsection for one circumference of the belt is obtained with the section for detecting a rotation reference point and the rotation reference point as a start point in belt rotation control (S21, S22). A difference between the learning value deviation of the present position and the learning value deviation one point before is calculated in the present position of the belt edge. Decision is made from the change rate between the learning value deviation of the present position and the learning value deviation one point before (s24, 25) relating to the traveling state of the belt.  The changing pulse number of a pulse motor is determined in accordance with the skew correction constant determined when the difference between the steering change offset constant determined by the state of the learning value deviation of the present position and the learning value deviation one point before is off the regulated range. The steering motor is rotated by as much as this value (S26, 27).

Title: Underwater position measuring system using transponder
Inventor: SATO NAOKI
IPC: G01S15/74
Filed: 1994-12-07
Abstract: PURPOSE: To provide an underwater position measuring system which can accurately determine the position of an underwater object without being interrupted by noise. CONSTITUTION: A transponder 60 outputs acoustic waves of a prescribed frequency as a response signal R0 for a prescribed period of time upon receiving a call signal S0 from the transmitter 59 of an underwater position measuring instrument. The signal processing means of the underwater position measuring instrument assumes that the response signal R0 has been received when the response signal from the transponder 60 received by means of a plurality of hydrophones 19, 29, and 39 exceeds a prefixed threshold. At the same time, the signal processing means counts the number of times of reception of the response signal of the hydrophones from the transponder 60 exceeding the threshold.  Only when the count value coincides with the count value previously designated as the count value of the real response signal, the underwater position measuring instrument calculates the position of the underwater object by using the assumed receiving time of the response signal by regarding the response signal received by the hydrophones 19, 29, and 39 as the real resnonse signal.

Title: Power source circuit
Inventor: ASHIKAGA KOICHI
IPC: H04M19/08
Filed: 1987-11-30
Abstract: PURPOSE:To separate a control circuit from a power source at a non-using time and to erase unnecessary energy consumption by giving the output of an integration circuit, which is generated by the turning-on operation of a switch, as the power source and input signal of the control circuit and causing a switching circuit to be turning-on-operated based on the output when the input signal is given to the control circuit. CONSTITUTION:Since the turning-on input of an on-hook dial switch 15 goes to be the input signal of a control circuit 11 after it is converted to the output of an integration circuit 19, a chattering generated in the turning-on input is removed by the integration circuit 19 and abnormal operation caused by the chattering is evacuated without fail. When a line is turned off by the end of a calling, the signal of a low level is outputted from the control circuit 11 in order to turn off a transistor 6 with responding to the end of the calling and a switching circuit 9 goes to be turned off. In such a condition to turn off the line, an input impedance 2, which is observed from a chip terminal 2 and a ring terminal 3, goes to be infinite in principle. Hence, a battery for power source back-up is unnecessarily eliminated.
