IPC: H01T4/12
Filed: 1988-06-29
Abstract: PURPOSE:To minimize the size of an insulative container by forming the container into a specific shape by a mad casting method and making the lengths of inner and outer longitudinal walls longer than the length between metallized layers. CONSTITUTION:Mud of almina is formed, molded with molding and dried. It is then sintered in a high temperature in the air to obtain a container 1. The container 1 is provided with wrinkles 1d2 on inner and outer surfaces thereof. The container 1 is formed in a ceramic cylinder with wrinkles 1d2 whose trough portion 1e has uniform thickness. With this arrangement, outer and inner longitudinal wall lengths l1 and l2 of the container 1 are made longer than the length between a pair of metallized layers 4 and 5 at the end of the container 1. As a result, a surface leak current between the metallized layers 4 and 5 are reduced and a short-circuited creep voltage at the inner and outer surfaces of the container 1 is improved. Furthermore, the thickness of the trough portion 1e of the wrinkle 1d2 is almost uniform. The trough portion 1e thus exhibits insulation proof stress endurable against mechanical strength. The container is therefore constituted in a minimum size.

Title: Anemometer
Inventor: AWANO SEIICHI
IPC: G01P5/07
Filed: 1980-11-14
Abstract: PURPOSE:To improve accuracy by reducing influence of friction of a bearing, in a propeller type anemometer, by utilizing an axial-flow compressor blade which produces a load torque equilibrating a torque produced by a wind force turbine blade. CONSTITUTION:On wind force turbine blades 1 and 1' attached to a boss 3, air is expanded and accelerated to produce an output, whereby the blades 1 and 1' are revolved. On axial-flow compressor blades 2 and 2' which are provided on the other end of a rotary shaft 4 on which the turbine blades 1 and 1' are also provided, air is compressed and energy is absorbed. As the major portion of the output of the turbine blades 1 and 1' is used for driving the compressor blades 2 and 2', revolution of the blades can be maintained low at the time when wind velocity is high. Further, since friction torque of bearing is small, an indication error due to said variation becomes small. Further, rotating signal of the blade is detected by a rotating pulse generating pinion 10 and a magnetic sensor 12.

Filed: 1988-06-27
Abstract: PURPOSE:To shorten the access time for data read and to stabilize the operation by using a current mirror type amplifier and eliminating flowing nodes to quickly amplify a minute signal without having a bad influence upon the bit line potential. CONSTITUTION:When information in a memory cell 1 is read out onto a bit line BL, the change of the bit line potential is quickly amplified by a current mirror type amplifier 30 and is outputted to read data transmission lines OL and the inverse of OL. The potential of the line, the inverse of OL is quickly discharged to the earth potential through transistors TRs Q18 and Q16 by a column decode signal. The potential of the line OL is the precharge potential as it is. Since bit lines and data transmission lines are not directly connected, the load capacity and the potential level of data transmission lines have no influences upon lines BL and the inverse of BL. Consequently, information is accurately and quickly read out.

IPC: G11B5/027
Filed: 1988-06-28
Abstract: PURPOSE:To prevent an unrecorded part from being generated in a recording signal against an input signal by controlling a delay time of a signal delaying means and executing delayed sound recording, when a terminal detecting part has detected a fact that a tape running system inverts the running direction in a terminal of a magnetic tape. CONSTITUTION:When a tape reaches a terminal in the course of sound recording in the regular direction, and a detecting signal from a terminal detecting element 14 is outputted to a running control part 15, the running control part 15 sets immediately the running direction of a tape running system 11 to an inverted sound recording state. The output from the terminal detecting element 14 is outputted to a terminal detecting part 3, as well, therefore, in the tape terminal, a delay time of a signal delaying means 2 is switched by an output of the terminal detecting part 3. Subsequently, by setting the delay time at the time of inverted running to about one second required for switching the running direction by the tape running system 11, delayed sound recording is executed against an input signal at the time of inverted running, therefore, an unrecorded part against the input signal can be eliminated.

Abstract: PURPOSE: To effectively remove nitrogen in simplified operation, by oxidizing nitrogen of nitrogen compounds in waste water by aeration, reducing the nitrogen in the presence of a hydrogen-dontating source, and removing the nitrogen in a gaseous state outside the system.  
     CONSTITUTION: A requeired amont of active sludge is precharged into a vessel which can reserve one or a few day's amount of nitrogen compound-contng. organic waste water. One day's amount of the waste water is reserved in the vessel, while being gradually aerated. Therafter, the waste water is aerated by a sparger at the bottom of the vessel, so that nitrogem of the nitrogen compounds in the waste water is oxidized into a nitric or nitrous state. The waste water is let alone as such for a while, and kept under an anaerobic condition while completely inhibiting oxygen inflow into the system from the outside. To the waste water under this condition is added a required amount of crude water or alcohol to reduce the nitric or nitrous nitrogen, and the waste water is sufficiently agitated under the anaerobic condition. Thus, the nitric or nitrous nitrogen is reduced and discharged in gaseous state outside the lsystem. Thereafter, the waste water is let alone as such, supernatant separated from active sludge is drained, and the same treatment is repeated in succession.
