Title: Production of polyester-based polymer, polyester-based toner binder and electrophotographic developing agent composition
Inventor: INAGUMA KAZUNARI
IPC: C08G63/78
Filed: 1991-07-11
Abstract: PURPOSE:To obtain a polymer having controlled molecular weight distribution and excellent handling of high-viscosity polymer in high reactivity and in high productivity by a simplified process by using a specific horizontal polymerizer and a forced extrusion reactor in the latter period of polymerization process. CONSTITUTION:In producing a polyester polymer from a di- or polyfunctional acid component and a di- or polyhydric alcohol, the production process is divided into the former period wherein the reaction degree reaches 20-90% given reaction end and the latter period of reaching the reaction end, in the latter period, the polymer is produced by using both a horizontal polymerizer by extrusion flow and a forced extrusion reactor equipped with plural feed openings. Since the distillate of volatile components contributes to polymerization degree in a continuous polymerization reaction, effects can be increased by regulating a flow rate of inner gas and introducing it to the reactor.

Title: Hitting detector
Inventor: TAMURA YUZURU
IPC: A63B71/06
Filed: 1987-07-10
Abstract: PURPOSE: To precisely detect a hitting force in every directions, by incorporating a shock detecting surface which can uniformly detect hitting forces in different directions, in a hitting sensor. CONSTITUTION: When a piezoelectric element 8 receives an abrupt stress by hitting of a Karate player (an empty hand defense art of Ryukyuant), a voltage is produced due to a piezoelectric effect of the piezoelectric element 8. An output voltage is produced only when a hitting is detected. A voltage signal generated from the piezoelectric element 8 is delivered to a comparator 5 whose signal is FM-modulated in a modulating part 6. Thus modulated signal is transmitted from a transmitting part 7, and is received by a receiver 3. Thereafter, an alarm is issued for a predetermined time. At this time, a hitting sensor part 1 receives a shock by hitting in every directions. Since the hitting sensor part 1 has a semispherical shock detecting surface 11, the area of the shock detecting surface 11 which receives a shock in every directions is constant.  Accordingly, even with any hitting force in any direction, the value (detected value) of output/hitting force can be set to be uniform.

Filed: 1989-07-03
Abstract: PURPOSE:To prevent hit of an RF signal at changeover by switching a reed switch, an attenuation circuit and a switch circuit connecting to ground interlockingly and enclosing the reed switch with a conductor. CONSTITUTION:A control circuit 15 causes a current to flow to a coil 11b, a reed switch 11a is closed by the magnetic field and a switch circuit 13 is opened, then the RF signal is not attenuated. The flowing of the current to the coil 11b by the control circuit 15 is stopped to eliminate the magnetic field and the switch 11a is opened and the switch circuit 13 is closed, then the RF signal is optionally attenuated through an attenuation circuit 12.
