Title: Fuel pump control device for internal-combustion engine
Inventor: YAMAGUCHI HIROSHI
IPC: F02M37/08
Filed: 1981-10-26
Abstract: PURPOSE:To economize the wasteful consumption of electric power and improve the cost of fuel by intercepting the electric source circuit of a fuel pump at the time of fuel cutting. CONSTITUTION:A fuel-cut detector 6 outputs a fuel-cut signal S2 to give a high level for fuel supply and a low level for fuel-cut. Meanwhile, a control circuit 5 is composed of a switch circuit 7 to be on when the fuel-cut signal S2 is in the high level and off when in the low level, a switch circuit 3, and a series circuit of resistances R2 and R3. Consequently, when an engine is off, and when the engine is on but fuel is cut, a switch circuit 3 or 7 is off, and a transistor Q is off. Then, a fuel pump 4 is intercepted from its electric source circuit, and stopped.

Title: Electromagnetic shock tool
Inventor: JIYORUJIYU JIYATSUKUME
IPC: E02D11/00
Filed: 1982-10-01
Abstract: A two-directional percussion implement selectively adaptable both for driving in and for extracting, e.g. piles, from the ground, includes two coaxial electromagnetic coils whose movable armatures are represented by extremities of a reciprocable ram. Opposite anvils, one of which is adapted to be coupled with a driven element, are interlinked by a non-magnetic shaft traversing the ram. When the implement is intended for drilling operations, a rotary drive imparts rotation to one of the anvils via a connection permitting independent rotation and reciprocation. The shaft in this case has a central channel for taking samples or for conducting drilling fluids. When adapted only for axial percussions, the implement is vertically suspended on a cable via a shock absorber.

Abstract: PURPOSE:To restrain wear of refractory and to further improve decarbonizing velocity by forming cross-sectional shape of a reduced pressure cylindrical body to elliptic shape and making eccentrically of setting position for a porous plug arranged at the bottom part of a ladle to major axial direction of the ellipse of reduced pressure cylindrical body. CONSTITUTION:The cross section of reduced pressure-cylindrical body 1a is formed to elliptic shape and the porous plug 13 in the ladle 7 is arranged at the eccentric position as far as possible to the major axial direction of the ellipse in the range of enclosing float-up bubbles 18 from the porous plug in the reduced pressure cylindrical body 1a.

Title: Long life galvani primary battery
Inventor: PAURU RIYUETSUCHI
IPC: H01M6/12
Filed: 1980-12-04
Abstract: Disposed between the positive electrode and the negative electrode in addition to the separator layer is an electrolyte-impermeable inert film or foil about 5 to 50 microns thick. The film or foil includes a very small current-focusing aperture produced by piercing, punching, or melting. The entire electrolytic current is focused through this aperture. The area of the aperture is at least ten times smaller than the surface area of the separator layer. The thickness l of the film or foil and the radius ri of the aperture are governed by the relationship 4l/ri</=10. The electrolyte-impermeable film or foil is sealingly clamped between the positive electrode and a sealing ring at the edge of the cell. The film or foil may be of a synthetic resin polymer material, of nickel, or of a nickel alloy. Self-discharge is decreased by the construction of the cell. The cell may be in a flat form without any appreciable decrease in the energy density taking place. Furthermore, the cell presents advantages when electrolytes having a low freezing point are used. The cell is well suited as a power source for electronic watches, pacemakers, or as a voltage source for electronic memories.

Title: Optical information recording method and information recording medium
Inventor: OBARA SHINICHIRO
IPC: G11B7/243
Filed: 1987-07-10
Abstract: PURPOSE:To enable information reading with a commercially marketed CD player by rotating an information recording medium formed by providing a recording layer which is decreased in transmittivity by projection of light on a substrate and providing a reflecting layer thereon at a specific constant linear speed and projecting light on the recording layer thereby recording a CD format signal thereon. CONSTITUTION:A material which records the information by a change in reflectivity to light and is decreased in the transmittivity by the projection of light, i.e., is decreased in the transmittivity by the heat of photoirradiation is used for the recording layer provided on the substrate of the information recording medium. The reflecting layer is further provided on the recording layer. The CD format signal is concentrically or spirally written on the recording layer when light for recording such as semiconductor laser light is projected on this information recording medium from the substrate side while the medium is rotated at the specified linear speed within a 1.2-1.4m/sec range. Since the recording layer of the information recording medium recorded with the information by the change in the reflectivity is the high reflectivity in such a manner, the recorded signal is readable with the high accuracy with the commercially marketed CD player.

Title: Automatic cartridge ejecting system of roll type multi- item key input device
Inventor: KUMOI SHIGETSUGU
IPC: G06F3/023
Filed: 1983-09-19
Abstract: PURPOSE:To prevent the winding curl of a cartridge which is caused when the cartridge is left in an input device for a long period of time, by giving an automatic cartridge ejection command to eject the cartridge automatically when a power supply is cut off. CONSTITUTION:When the business work is over, a power supply OFF control signal is applied to a monostable multivibrator circuit 24 via a power supply application cut-off control circuit 22. Then this control signal is delayed by a prescribed amount to attain the automatic ejection of a cartridge. At the same time, the power supply OFF control signal is discriminated by an ejection command output part 23. Then an ejection command is delivered to a roll type multi-item key input device 19, and an ejection control circuit 26 of the device 19 disciminates the command. Then a page selection mechanism 28 is controlled exactly in the same way as in the case when an ejection key 27 is pushed. Thus the cartridge is ejected. When this ejection of the cartridge is over, the power supply is cut off. This automatic ejection of a cartridge prevents the winding curl of the cartridge which is produced when it is left in an input device for a long period of time.

Abstract: PURPOSE:To obtain a porous antimicrobial material, by reacting a porous material having the surfaces treated with a silane coupling agent having alkoxy groups with a phenolic derivative having alcoholic hydroxyl group in the presence of a Pd-C catalyst in nitrogen atmosphere. CONSTITUTION:An inorganic porous material (e.g. porous glass, ceramic, zeolite or silas porous glass) is sufficiently brought into contact with a silane coupling agent having alkoxyl groups (preferably gamma-aminopropyltriethoxysilane) in a solvent containing the silane coupling agent dissolved therein while refluxing and heating to carry out surface treatment. The resultant material is then reacted with a phenolic derivative having alcoholic hydroxyl group (e.g. p- hydroxybenzyl alcohol) in an inert gas atmosphere, such as N2, using Pd-C as a catalyst to afford the aimed porous antimicrobial material. This antimicrobial material is capable of reducing residual toxicity as compared with that of gaseous or liquid antimicrobial agents and continuous sterilization and treatment in large amounts can be carried out with simple operation.
