Title: Endless belt deviation preventing mechanism
Inventor: KOGA HIROTO
IPC: B65H5/02
Filed: 1995-06-29
Abstract: PURPOSE: To prevent the generation of waves and wrinkles of an endless belt on a recording material carrying surface during controlling of belt deviation so as to stably carry the recording material by arranging a belt deviation detecting member and a displacing means in a belt hanging and tensioning member other than the recording material carrying surface. CONSTITUTION: An endless belt 1 is wound in a downstream driving roller 2, an upstream deviation correcting roller 3 and a follower roller 4 which constitute a belt hanging and tensioning member and moved in an arrow direction K1. The deviation correcting roller 3 is for such inconveniences as one-side deviation, meandering and the like occurring in the endless belt 1 and this is always pressed by a tension spring 12 in a direction for making the endless belt 1 tense. One end side of the deviation correcting roller 3 is supported on a swing bearing 9 via a detecting ring 8 so as to be swung up and down. Since the detecting ring 8 and the deviation correcting roller 3 are arranged in sides opposite photosensitive drums 5a to 5d as transfer and carrying surfaces, no waves or wrinkles are generated on the transfer and carrying surfaces.

Title: Flat-type speaker
Inventor: MATSUDA JIYUN
IPC: H04R9/04
Filed: 1978-12-26
Abstract: PURPOSE:To suppress the disturbance of the frequency characteristics due to the divided vibrations of the diaphragm by attaching the additional mass to the diaphragm. CONSTITUTION:Drive point P2 of diaphragm 1 due to voice coil 4 is set more inside than logical node P1 of the divided vibrations of diaphgram 1, and additional mass 15 is attached at the four corners each. Thus mass 15 of the proper weight is attached at the proper position of diaphragm to prevent occurrence of the divided vibrations of diaphragm 1 and then to improve the frequency properties. This is due to the fact: in case point P2 is set more inside than point P1, the weight balance of diaphragm 1 is shifted to outside from inside virtually by attaching mass 15 more outside than point P1; and as a result the overall balance can be improved for diaphragm 1.

Filed: 1990-06-22
Abstract: PURPOSE:To allow one terminal equipment to make simultaneous communication with other terminal equipments whose number is logical channel number or over by using part of plural logic channels preserved by a trunk of a packet exchange as a logic channel for fixed connection and using the logic channel so as to set a fixed logic communication line. CONSTITUTION:When a terminal equipment PP1 uses logical channels C1 to be going to send a data to a packet terminal equipment PP2, the terminal equipment PP1 selects one channel among the channels C1, and generates a data packet and sends it to a packet exchange XX. Upon the receipt of the data packet, the exchange XX identifies the called packet terminal equipment PP2 from the data packet and selects one logic channel among logic channels C2 formed fixedly. Then the exchange sends logic channel identification information in the data packet sent from the terminal equipment PP1 to the terminal equipment PP2. Thus, the terminal equipment PP2 sends a reception enable packet to the terminal equipment PP1.

The experimenter can set a parameter without storing a matching property of the parameter value between the wavelength scan parameter and the time scan parameter. In this way, the redundancy of the parameter value can be eliminated, the memory capacity is saved, and the inconsistency between the parameter values is prevented.

IPC: G11B15/03
Filed: 1986-07-14
Abstract: PURPOSE:To ensure measurement of time without providing any timing signal generating circuit by providing a servo circuit to control the revolution of a rotor to an approximately fixed level based on the signal detected from the revolution of the rotor and using the detected signal as a timing signal. CONSTITUTION:A pause signal is sent to an input port 11 from a control circuit 25 with push of a pause button 24 and at the same time an interruption request signal is sent to a terminal 15. Thus a pinch roller is detached from a capstan and the feed of a magnetic tape is stopped. Thus a pause mode is set. In this case, however, motors 20 and 22 continue their revolutions to output an approximately fixed detection signal via a servo action. This detection signal is sent to a CPU 5 via a terminal 14 as a timing signal. The CPU 5 counts these signals to take an 8min pause and sends a control signal to the circuit 25 via an output port 10. The circuit 25 sends a stop signal to a drum servo processing circuit 19 to stop the drive of a drum. Thus the measurement of time is possible without providing any timing generating circuit.

An absorptive material of electrolyte, the absorptive electrolyte quantity of which is increased depending upon the electrolyte concentration variation during the charge and decreased depending upon that during the discharge, is provided in the electrolyte layer or contacted to the electrolyte layer. Then, the absorbed electrolyte quantity by the absorptive material in the electrolyte concentration under the charging condition is increased and the quantity included in electrode plates or separators is decreased. Therefore, the internal pressure rise can be suppressed even when a rapid charge with a large current is carried out. On the other hand, in the electrolyte concentration in the last stage of the discharge, the electrolyte quantity can be increased to prevent the falling off of the cell capacity.
