Title: Alkaline zinc storage electrode
Inventor: FUJIWARA YOSHIKI
IPC: H01M10/28
Filed: 1987-09-19
Abstract: PURPOSE:To increase electrolyte retention capability by adding a porous SiO2 powder having small particle size compared with zinc active material as a wetting agent to a zinc electrode mainly comprising zinc oxide and metallic zinc. CONSTITUTION:A stacked body is mound and covered with a heat shrinkable tube 4, then inserted into an outer jacket can 5. A sealing body 6 is fitted to the opening of the outer jacket can 5 through an insulating gasket 7, a negative conductive tab 8 is connected to a zinc electrode 1 and the outer jacket can 5, and a positive conductive tab 9 is connected to a nickel electrode 2 and the sealing body. Silica is uniformly distributed as a wetting agent in the zinc electrode 1. Since the silica has sufficiently small particle size and is porous, it uniformly distributes in the zinc electrode and exists in the charge-discharge reaction site in a particle level, and has high electrolyte-retention capability. The silica serves as a wetting agent during charge-discharge cycle and retards the passivation of zinc active material, and increases the electrolyte retention capability.

Title: Cathode structure for magnetron
Inventor: KIN KENSHITSU
IPC: H01J23/05
Filed: 1996-09-05
Abstract: PROBLEM TO BE SOLVED: To provide efficiency as high as predetermined percentage even at an anode voltage lower than a given value by adjusting an interval between filaments in a spiral cathode. SOLUTION: A relational coefficient K of a magnetron is given by the following expression: K=(da-dc) /S, wherein dc represents a cathode diameter of a cathode 17; S, a cathode stem; and da, an anode diameter. The cathode stem S of a filament wound spirally and adjacent to a cathode is adjusted in such a manner that the relational, coefficient K is equal to or smaller than 3.7. At this time, an electron efficiency ηe of the magnetron is determined by a given equation based on a charge quantity (e) and a mass (m) of an electron, an operating frequency (f), a reference voltage V0 between vane walls, the vane number N and an anode voltage Va . Consequently, the efficiency of the magnetron is increased by taking advantage of dependency on a da/dc value without any increase in oscillation starting voltage.  The magnetron having the cathode 17 can be operated with a high efficiency of 70% even at the low anode voltage by adjusting the cathode stem S.

IPC: H04W84/02
Filed: 1987-09-19
Abstract: PURPOSE:To suitably control the sound volume of ringing automatically by setting the sound volume of ringing corresponding to the result of comparison between a set noise and a collected noise. CONSTITUTION:In each slave station, encironmental noises are collected by a sound collecting means 1 provided with a microphone 11 and a filter circuit 12. The level of thus collected noise and that of a set noise are compared with each other in the comparison circuit 21 of a comparison means 2, and the results of comparison undergo an A/D converter 22, then sequentially stored in a memory 23, so that a comparison-result average value is outputted from an average value output circuit 24. Then, the sound volume of ringing is automatically and suitably control led by a setting means 3 comprising a sound volume selection circuit 31 and a sound volume setting circuit 32. As a result, that ringing can not be heard because of its too low noise or that the sound volume of the ringing comes too much higher than that of environmental noises, can be prevented.

Title: Remote starting method and device for vehicular engine
Inventor: OKISHIMA KIYOSHI
IPC: F02N11/08
Filed: 1996-08-19
Abstract: PROBLEM TO BE SOLVED: To provide a method and a device for accurately detecting start-up of an engine with minimum connecting wiring when the engine of an automobile is started by the remote control. SOLUTION: When a starter motor is operated to start engine of an automobile, power supply voltage from a battery is fulctuated by the fluctuation of rotational torque of cranking. If this is detected by a cranking detecting circuit 47, the engine is not started, and it is found that cranking is now performed by the starter motor. When any cranking pulse is not detected, it is judged that the engine started, and the operation of the starter motor is stopped. When the engine starts to rotate at the certain engine speed or more, an alternator starts to generate power, however, pulsating waves are always superimposed on the output voltage. If this is detected by an alternator noise detecting circuit 49, it is found that the engine is continuously rotated. When these detections are not performed, a CPU 18 turns off all relays to return them into the initial state.

Title: Method of reducing nitrogen oxides
Inventor: ONO SHOICHI
IPC: F23C99/00
Filed: 1999-08-23
Abstract: PROBLEM TO BE SOLVED: To promptly and efficiently decompose nitrogen oxides by permitting nitrogen oxides in an exhaust gas which was generated by main fuel combustion to be reduced by a reducing gas which was generated by simultaneous combustion of solid combustibles as an secondary fuel. SOLUTION: Combustion in a combustion device consists of mixed combustion of main fuel combustion and combustion using solid combustibles, i.e., combustible solid as an secondary fuel. The amount of the secondary fuel fed to the combustion device is determined relatively to the quantity of heat from the fed main fuel. The amount of the fed secondary fuel is equivalent to the amount by which the heat quantity ratio of the secondary fuel occupies 5-50% of the total heat quantity brought to the combustion device by the main fuel and the secondary fuel. Further, injection is conducted in a burning device by an exclusive nozzle for the secondary fuel at a speed lower than the injection speed of the main fuel in order to allow produced reducing gas to reductively react, neither too much nor too less, on nitrogen oxides in the exhaust gas of the main fuel combustion.  Thus, by conducting injection at such a speed and forming a reducing flame, nitrogen oxides in the main fuel combustion exhaust gas can be sufficiently reduced.

Title: Burnishing tool for roller
Inventor: MIYAMOTO TAISUKE
IPC: B24B39/04
Filed: 1990-09-06
Abstract: PURPOSE:To shorten the partcontacted with the face to be worked even in case of its shape being in a roller shape as the whole, by forming plural projection bars on the outer surface of the shaft like tool substrate in a circular section, and facing the side edge of at least one projection bar of those projection bars in the direction crossed with the bus along the circumferential direction of the tool substrate. CONSTITUTION:A high bearing is obtained, by contacting with the face to be worked with the projection bar 3 formed on the outer surface of a tool substrate 1, and the contact length becoming short with its being limited. When this tool substrate is rolled along the face to be worked in the radial direction, the projection bar causes a plastic deformation with its pressurizing the face to be worked, and burnishing finish is performed. In that case, either one projection bar is faced to the direction crossed with the bus along the circumferential direction of the tool substrate at its side edge part, so the part receiving a plastic deformation in the face to be worked is moved in the axial direction of the tool substrate, therefore the burnishing finish is performed, by rotating the tool substrate so that the rotation phase of the tool at the same place differs on each rolling of the tool repeatedly.

Title: Chassis, body or parts and manufacture thereof
Inventor: YAMAZAKI SHUNPEI
IPC: B63B59/04
Filed: 1989-09-12
Abstract: PURPOSE:To enhance wear resistance of the surface of a base body having an unevenness or a large-sized base body and to prevent sticking of dirt and generation of static electricity by forming a film wherein carbon contg. halogen element such as fluorine is incorporated as a main component on organic substance. CONSTITUTION:Coating of organic substance is performed on a chassis, a body, a bumper and the other parts of an automobile, a ship and an airoplane wherein wind shield is performed thereby. As a protective film of the coated face, a film is provided wherein carbon containing halogen element such as fluorine is incorporated as a main component. This film prevents generation of static electricity which is easily generated by wind shield accompanied with dirt. In its turn, this film prevents turbidity resulting from sticking of dirt and wear of the coated face and thereby the clear face in the initial stage of coating is always held. It is more desirable that static electricity is more prevented by closely sticking a plasma-polymerized film having comparatively low resistance value of 1X10<7> - 5X10<13>OMEGAcm resistivity as the protective film.
