Title: System for testing signal processing lsi
Inventor: YOSHIKI TOSHIJI
IPC: G06F11/267
Filed: 1985-04-02
Abstract: PURPOSE:To make it possible to perform a test by one testing terminal, by providing a testing selector in a signal processing LSI and connecting the same to an external demultiplexer and an external memory. CONSTITUTION:A signal processing LSI2 is tested by selecting the parallel signal issued out from an objective digital signal processing block (DSP1)3 by a selector 9 operated in synchronous relation to an internal clock 8 and sending out said signal from a testing terminal C to accumulate the same in a memory 11 through an external demultiplexer 10. This operation is repeated a number of times corresponding to the number of signal bits. This accumulated memory content is converted by a D/A converter 12 to perform evaluation by a measuring device (M2)13. Therefore, only one terminal C may be used as the testing terminal and it is unnecessary to make a chip size large and the initial evaluation of planning is enabled and a planning time can be shortened.

Title: Power system
Inventor: YAMAMOTO KAZUE
IPC: F03B17/04
Filed: 1987-03-23
Abstract: PURPOSE:To enable taking out the required power simply and positively in utilizing buoyancy in liquid and lever action or the like, by reciprocating a lever member via a motor-driven mechanism with the lifting motion of each float installed in each of plural tanks. CONSTITUTION:When a valve 38 is opened, a liquid in a tank 10 at the left flows into another tank 10 at the right via a liquid pipe 12, If so, a float 11 at the left goes down while another float 11 at the right goes up, whereby each pinion 19 at both symmetrical sides is rotated counterclockwise by each rack 17 at both symmetrical sides. Consequently, each rotating cylinder 21 at both symmetrical sides is rotated counterclockwise via a chain 23, and each pinion 29 at both symmetrical sides is rotated counterclockwise as well via each transmission 25 at both symmetrical sides, thus each moving member 15 at both symmetrical sides is moved to the left. In consequence, a lever member 3 is rotated counterclockwise with a fulcrum body 2 to a machine body 1 as the center.

Title: Control circuit of fan motor energization
Inventor: NUMAKURA MAKOTO
IPC: H02P27/02
Filed: 1986-03-27
Abstract: PURPOSE:To reduce the pulsation of ventilation by dividing an energizing pattern into multiple block periods and setting the ON-OFF period during each block period so as to get a predetermined energizing rate in an energizing pattern. CONSTITUTION:A control circuit 13 answers zero cross signals of an input terminal 16 and changes the output of an output terminal 17 to control a triac 27 through a phototriac-coupler 22. In this control circuit 13 the energizing rate of a fan motor 2 remains the same as before, but the ON-OFF period of a switching element is set up in each block period so that a predetermined energizing rate can be obtained in an energizing pattern. Thus an energized cycle of ON and OFF becomes shorter and the pulsation of ventilation disagreeable to human body can be reduced along with theinfluence of the inertia of the fan motor 2.

Title: Image forming device and method
Inventor: YAMAMOTO TAKESHI
IPC: G03G15/08
Filed: 1994-03-14
Abstract: PURPOSE:To eliminate the fusion of toner at the time of transfer and faulty transfer such as fogging in an image forming device using photoconductive toner. CONSTITUTION:The layer thickness of the photoconductive toner TN applied to a transparent conductive carrier 2 is made to a uniform thin layer with an elastic blade 4, and the thin layer is triboelectrified and electrostatically charged to be negative. A counter electrode 6 is arranged at the position having a specified distance (x) from the carrier 2 and transfer electric field is formed in a transfer area S with a power source 7. When the toner TN is irradiated using an exposing means 5, the resistance of the toner TL which is irradiated is lowered and positive charge is injected from the carrier 2. The toner TN which is electrostatically charged to be positive is transferred to a transfer material P on the counter electrode 6 from the carrier 2 through the transfer electric field. Since the toner layer on the carrier 2 and the recording material P do not come in contact with each other at the time of transfer, the fine adjustment of contact pressure is not necessitated and the toner fusion and the fogging, etc., are eliminated differently from a contact transfer system.

Title: Negative electrode of lithium for secondary battery
Inventor: GOTO FUMIO
IPC: H01M4/13
Filed: 1987-03-24
Abstract: PURPOSE:To obtain a negative electrode of lithium including a lithium active material holding body of a long life which is less likely to be formed into powders and therefore removed by composing a negative electrode of lithium active material and an active material holding body consisting of a core material and coating of aluminum or aluminum alloy provided through a layer of alloy.

Abstract: PURPOSE:To improve safety by connecting a pilot circuit for a pilot selector valve used for a travel to an electric circuit for a flasher via a pressure switch, and lighting a flasher lamp with a signal from the circuits. CONSTITUTION:A pilot circuit 53 for pilot selector valves 39t and 39r used for a travel is connected to an electric circuit 18 for a flasher via a pressure switch 51. In the stop mode of a turning motor 4, no pilot pressure acts on the pilot pressure receiving section 21 of another pressure switch 20 and, therefore, the circuit 18 is not energized electrically. Then, when one or both of travel pedals 34t and 34r are operated, pilot pressure introduced from the shuttle valve 50 of the circuit 53 acts on the pilot pressure receiving section 52 of a switch 51 via an oil passage 54. As a result, the pressure switch 51 is actuated and the circuit 18 becomes live, thereby lighting a flasher lamp 6.
