Inventor: HATA KATSUHIKO
IPC: F16G1/00
Filed: 1989-08-14
Abstract: PURPOSE:To provide an economical thermoplastic elastomer transmission belt which is excellent in an antistatic function and mechanical characteristics by a method wherein the transmission belt is formed by using a tension substance to which an adhesive containing a polyboron compound is adhered and an thermoplastic elastomer. CONSTITUTION:A transmission belt is formed by using a tension substance 1 to which an adhesive containing a polyboron compound is adhered and a thermoplastic elastomer 2, and a nitrogen compound of which a charge moving complex consists is used for a polyboron compound. Since the polyboron compound is contained only in the tension substance 1 of a belt and an adhesive and the polyboron compound is a nitrogen compound of which a charge moving complex consists, nitrogen serves as a doner and boron serves as an acceptor, electron is easily transfered between nitrogen and boron to effect volume continuity, and an antistatic function on a belt surface can be achieved at a low cost.

Title: Disk breakdown preventing device
Inventor: SENTODA JITSUO
IPC: G11B19/00
Filed: 1989-08-17
Abstract: PURPOSE:To eliminate the need of such a work as a periodical replacement of a battery, etc., and also, to manufacture the device at a low cost by executing the backup at the time of abnormality of a power source by a capacitor only during the necessary minimum period without using the battery. CONSTITUTION:When an AC input 25 from an AC power source 23 is stopped by interruption or power failure, etc., abnormality is generated in a DC output 14 of a first power unit 13. A power source abnormality detecting circuit 15 detects it, and sends out a detecting signal 32 of a high level to a stop control circuit 17. In such a case, normally, a DC output 24 of a second power unit 22 also becomes abnormal, but since a capacitor 21 contained in this second power unit 22 executes immediate backup, a normal state can be maintained. As for this capacitor 21, it is required to have minimum capacitance to supply normal DC current only for a write time. In such a way, such a work as a periodical replacement of a battery, etc., becomes unnecessary, and also, the device can be manufactured at a low cost.

Not only the 2nd polarized light is utilized in this way, but also the unmodulated light of the 1st polarized light is utilized. The utilization of the greater part of the light of the light source is thus possible.

Title: Image recording device
Inventor: IJUIN KAZUYA
IPC: B65H16/00
Filed: 1988-08-25
Abstract: PURPOSE:To allow recording sheet to fall below a recording sheet storage section, even if the recording paper almost wound up climbs up the storage section, by arranging a platen roller in an area above the recording sheet storage section. CONSTITUTION:A platen roller 22 is arranged in a position where it does not touch the peripheral surface of a large diameter recording roll paper attached to a storage section 4 and it touches the peripheral surface of a minimum diameter recording roll paper 3 which climbs up the front wall 4a of the storage section 4. In addition, thermosensitive recording paper 3 is wound around a core 3a to become a minimum diameter recording roll paper. The recording roll paper 3 now in contact with the platen roller 2 is separated from the front wall 4a of the recording paper storage section by counter-clockwise rotation of the platen roller 2, and then again is returned to the bottom of the storage section 4. The smooth feeding of the recording paper is ensured by constituting the whole unit or part of the platen roller in an area above the recording paper storage section as described above, if the recording paper becomes small in diameter and unstable in movement. Thus the immobilization of the recording paper due to its stacking in a wedge-like form can be prevented.

Title: Method and apparatus for manufacturing pellet
Inventor: AZUMA KEIJI
IPC: B29B13/10
Filed: 1987-08-26
Abstract: PURPOSE:To reduce the mixing of metal powder in pellets and consequently obtain high quality pellet product by a method wherein material is extruded in the form of a string, cooled and solidified and, after that, the resultant cooled and solidified string-like material is ground by being applied with external force into pellets. CONSTITUTION:Material 50, which hungs down from an extrusion nozzle 12 is accumulated by being successively folding in one direction parallel to a revolving shaft 24 and in opposite direction on an accumulation catch face 25a by reciprocatingly guiding the material 50 on the accumulation catch face 25a through the reciprocating motion of a rocking lever 28.

Title: Motor positioning control method
Inventor: OSHIMA MASAO
IPC: H02P29/00
Filed: 1995-08-21
Abstract: PROBLEM TO BE SOLVED: To provide a motor positioning control method which uses a sliding mode control system to ensure the accurate and stable control despite the variance of load state value of a controlled system. SOLUTION: An observer block 113 estimates the quantity of state of the load or the angle of twist, i.e., the difference between the motor angle and the load angle, etc., based on an acceleration command Uref given to a motor and a motor angle θm showing the output of the motor. A sliding mode control block 115 selects and combines plural quantity of states to set a sliding mode control switching surface based on the estimated quantity of state, the rotational position information θm given from the motor and a motor position command θmref. Then the block 115 changes the sliding mode compensation value according to the positive or negative value that is calculated from those quantity of states. This changed compensation value is added to a feedback control system.  As the quantity of state of the load is restricted by the sliding mode control switching surface, the response of load is coincident with the target one despite the variance of parameter of a controlled system.
