Title: Link control state machine
Inventor: MCLAUGHLIN ERIC
IPC: H04L29/08
Filed: 1999-04-21
Abstract: PROBLEM TO BE SOLVED: To transfer the desired data in a network by separating a serial physical layer(PHY) from an MAC to select an MII-PHY and attaining the automatic negotiation when a link control state machine is kept in its 1st state. SOLUTION: In a 1st state 81, the link state is checked for a medium independent interface physical layer (MII-PHY). In a 2nd state 82, a medium access controller(MAC) transfers the data via the MII-PHY and a serial PHY is separated from the MAC. When the link state shows the establishment of a link, the state 81 is shifted to the state 82. In a 3rd state 83 where the MII-PHY is separated from the MAC and a test frame is sent via the serial PHY, the state 81 is shifted in a link time-out mode. Then the state 83 is shifted to a 4th state 84 where the data are transferred after the sending of the test frame has succeeded.

IPC: G05F1/12
Filed: 1980-08-19
Abstract: PURPOSE:To improve the efficiency of a device, and also to make it light, by alternately inverting an output of an electric power generating circuit. CONSTITUTION:A DC output from an electric power generating circuit 1 is supplied to a switching circuit 8, and is inverted alternately to plus and minus. That is to say, the switch is operated up and down by an output of an oscillator 7, and DC output voltage of the electric power generating circuit 1 is inverted alterately to the polarity of plus and minus. When the polarity of the switching circuit 8 is set to one side, the output voltage passes through as it is and is supplied to a load 6. On the other hand, when the polarity of the switching circuit 8 is reversed, the output voltage is applied to the load 6 in the opposite direction. When both the opertions are added, voltage of two times the output voltage of the electric power generating circuit 1 develops across the load 6.

Title: Linear actuator
Inventor: YOSHIDA HIROO
IPC: H02K33/18
Filed: 1992-04-07
Abstract: PURPOSE:To avoid a decrease in a control accuracy of an operating force of a linear actuator. CONSTITUTION:Propulsion forces responsive to amplitudes of currents supplied to coils 62, 64 are generated in the coils 62, 64, and a shaft 32 is moved by a resultant force of these repulsion forces. In a conventional linear actuator, an axial hole is not formed at the shaft 32, and hence it is necessary to extend leads 116, 112 for connecting the coils 62, 64 externally from a peripheral wall of a housing 10, but in this actuator, an axial hole 100 is formed at the shaft 32, and hence leads 112, 116 are inserted into the hole 100 and can be extended externally from an end wall 122. Thus, an installing predetermined space of the actuator in a radial direction can be reduced. Further, the leads 112, 116 do not apply radial forces to the shaft 32, and a decrease in a control accuracy of the operating force is avoided.

Title: Thermal transfer type electronic typewriter
Inventor: HIROTA KATSUTOSHI
IPC: B41J2/355
Filed: 1986-05-19
Abstract: PURPOSE:To obtain a thermal transfer type electronic typewriter capable of performing erasure under low current consumption, by mounting a second drive means stopping the supply of a current to a stepping motor during a time when a current is made to flow to a head by a second heating means heating the head for the second time in order to erase a horizontal one dot. CONSTITUTION:After the elapse of a definite time by a timer 13, the voltage applied to a stepping motor 4 is turned OFF by a second drive means 9. That is, if a value turning all of transistors OFF is outputted, a current ceases to flow to the stepping motor. At this time, if voltage is applied to a head 2 by a second heating means 8, a head current flows but an entire current gets off with small quantity and a peak current necessary for erasure can be reduced. Next, after the elapse of a definite time by a timer 14, if the voltage applied to the head 2 is turned OFF by a second cooling means 10, a current ceases to flow. As mentioned above, by dividing a time applying voltage to the head 2 into two, the head 2 can sufficiently discharge heat energy and high quality erasure is possible and the life of the head can be extended.

Abstract: PURPOSE:To prevent the occurrence of corona discharge in an oscillation capacitor due to voltage application and enhance safety by establishing a ratio equal to or less than the specified value between the inductance of the primary winding of a step-up transformer forming an oscillation circuit, and the capacity of the oscillation capacitor. CONSTITUTION:A commercial AC power supply 1 feeds DC power to an inverter circuit 14 after rectification through a rectification circuit 2, and a control section 10 turns on and off semiconductor switching elements 8 and 9. As a result, an oscillation circuit formed out of oscillation capacitors 3 and 4, and the primary winding of a step-up transformer 5 is excited, and the secondary winding of the transformer 5 and heater winding generate high frequency AC power. The high voltage AC current of the secondary winding is rectified with a high voltage rectification circuit 11 and a magnetron 12 outputs a microwave, upon receipt of high DC voltage from the circuit 11 and power from the heater winding. In this case, a ratio is set at 8 or smaller between the inductance of the primary winding of the transformer 5 and the capacity of the capacitors 3 and 4, thereby reducing voltage applicable to the capacitors 3 and 4, to a value equal to or less than 1,000V. According to this construction, no corona discharge is generated, and safety and reliability are enhanced.
