Title: Electromagnetic actuator
Inventor: YANAGIYA TOMOYUKI
IPC: H01F7/08
Filed: 1990-05-15
Abstract: PURPOSE:To obtain an electromagnetic actuator which is less in energy loss by forming a residual magnetic field having a peak in the axial direction of a cylindrical superconducting body and inserting a needle fitted with a plurality of electromagnets into the superconducting body and then, successively and alternately energizing the electromagnets so as to make the needle perform reciprocating motions. CONSTITUTION:A residual magnetic field is formed by impressing a strong external magnetic field upon a cylindrical superconducting body 1 using a suprconducting material having a large critical current density and pinning effect and needle 2 fitted with a plurality of electromagnets is inserted into the body 1. When an electric current is made to flow to one electromagnet 4 in the direction in which the electromagnet 4 is attracted to the magnetic field in the body 1, the needle 2 floats in a non-contact state and stops at the position where the electromagnet 4 comes to the peak position of the magnetic field. When the current to the electromagnet 4 is turned off and another current is made to flow to the other electromagnet 3 in the direction in which the electromagnet 3 is attracted to the magnetic field, the needle 2 floats in a non-contact state and stops at the position where the electromagnet 3 comes to the peak position of the magnetic field. By alternately turning on/off the electromagnets 3 and 4 in such way, the needle 2 is repeatedly raised and lowered and electric energy can be converted efficiently into kinetic energy.

Title: Nonaqueous secondary battery
Inventor: TOYOSAWA SHINICHI
IPC: H01M10/0569
Filed: 1987-05-21
Abstract: PURPOSE:To improve local discharge and a cycle life by using poly aniline containing BF4 in a specified ratio for an active material of a positive electrode. CONSTITUTION:Poly aniline is used for an active material of a positive electrode. In this case the poly aniline contains BF4 of 15 to 30 wt.%. By using the poly aniline as described above for an active material of a positive electrode, local discharge is repressed and a long lived secondary battery is obtained. When the content of BF4 is less than 15 wt.% or more than 30 wt.%, discharge capacity and capacity retention are lowered, so that the purpose is not attained. As for an active material of a negative electrode a combination of Li-Al containing Li of 25 to 65 atomic % is preferable.

Title: Fluorescent lamp lighting device
Inventor: DEGUCHI HIDEHIKO
IPC: H05B41/24
Filed: 1988-05-23
Abstract: PURPOSE:To intend cost reduction with one output serving the output of an I/O port by turning into 'OFF' the first switching part, switched by the signals from a comparing part and connected to the signal terminals of a preheating circuit and a lighting circuit, after the lapse of a preset time before turning the second switching part into 'ON'. CONSTITUTION:Turning a programmable unijunction transistor 30 into 'ON' turns a transistor 32 into 'ON'. Then, a transistor 43, connected to a preheating signal terminal 19 as well as a transistor 18 and a diode 17, is turned into 'ON' to turn the transistor 18 into 'OFF' with its base in 'low' state for making the preheating signal terminal 19 into 'high' state. At the same time when a preheating circuit 20 is turned into 'OFF', the other transistor 36, connected to the transistor 32, is turned into 'OFF', on account of which a transistor 39, connected to a lighting signal terminal 41, is turned into 'ON'. The output of an I/O port, conventionally requiring two outputs, can thus be served by only one output to permit cost reduction for promoting the shift to the multifunction of low-grade types.
