Title: Injectoin mold and injection molding method
Inventor: NISHII KOTA
IPC: B29C37/00
Filed: 1989-10-16
Abstract: PURPOSE:To enhance the productivity by performing coating process by the same mold as used at molding process by a method wherein coating delivery holes are provided so as to direct to the direction, which covers the mold surface corresponding to the surface required to be applied with coating film on a molded body over the region excluding the molding surface, which corresponds to the surface required to be applied with coating film on the molded body, and the region necessary for molding of the opposing mold. CONSTITUTION:A plurality of delivery holes 21b, through which coating 26 such as acrylic resin-based coating supplied from a coating metering and delivering device 25 through a feed hole 21a is delivered, are provided concyclicly so as to be spaced equally outside the region B necessary for molding of a male mold 21. The direction of injection of the coating 26 through the delivery holes 21b is set so as to cover the region C necessary for molding of a female mold 22 corresponding to the region B necessary for molding of the male mold 21. Accordingly, when the predetermined coating 26 is delivered through a plurality of said delivery holes 21b by the actuation of the coating metering and delivering device 25, the coating goes forward along the courses indicated with the arrows F, resulting in allowing to form a film having the required thickness over the whole surface of the region C of the female mold 22.

Title: Control device of variable flywheel in engine
Inventor: YAMASHITA AKINORI
IPC: F16F15/31
Filed: 1984-12-21
Abstract: PURPOSE:To enable a shock to be reduced when a subflywheel is engaged, by engaging the subflywheel separating its engaging speed when it is in a low and a high speed. CONSTITUTION:A control device decides an absolute value of a difference between an engine speed NE and a subflywheel speed NF. When this absolute value is in a value DELTAN or less, a step S6, outputting an engagement signal to a solenoid, engages a subflywheel 7. When the absolute value is decided in a value no less than the value DELTAN, the control device returns to a step S1. That is, the control device, providing an engagement region giving a preset margin of a value + or -DELTAN to the subflywheel speed NF, engages the subflywheel 7 when the engine speed NE reaches said engagement region. Accordingly, a shock is eliminated when the subflywheel is engaged.

IPC: B03C3/34
Filed: 1998-09-22
Abstract: PROBLEM TO BE SOLVED: To reduce dust passing through a device together with air without being stuck to dust collecting pole plates. SOLUTION: Air flow flows into a dust collecting cell 1 from an ionize part 2. At the dust collecting cell 1, an electrical fielded is generated between dust collecting pole plates 11 by the dust collecting pole plates 11 and a magnetic field in horizontal direction to the dust collecting pole plates 11 is generated between the dust collecting pole plates 11 by a coil 12. The charged dust receives the force in the dust collecting pole plates 11 direction by the electrical field and also the Lorenz's force in the dust collecting pole plates 11 direction by the magnetic fields. The charged dust is adsorbed to the dust collecting pole plates 11 by receiving these forces.

IPC: G01N21/35
Filed: 1998-08-19
Abstract: PROBLEM TO BE SOLVED: To provide a method and an implementation apparatus thereof that can determine very accurately road surface condition, especially with respect to the existence of water, ice and/or snow, at relatively low price, independently of road coating. SOLUTION: In a determining method of road surface condition, back-scattered light from road surface is decomposed to spectrum components and a change with respect to intensity of back-scattered light obtained thus is evaluated. Therefore, back-scattered spectrum with respect to a wavelength of a dried road surface is evaluated by mathematics function with free parameters, and the function is multiplied by an exponential function absorption term describing light-transmission of a water layer with a specified thickness. Then, a change of mathematics function with respect to a wavelength of intensity of back-scattered light, which impinges on a receiver 5, is obtained. Based upon actual measurement values, free parameters of function for an approximation as correct as possible is calculated, thereby obtains especially thickness of a water layer.  An implementation apparatus thereof is a spectrometer, which uses an absorption device as a substitute for a dispersion device and is directly installed on a row of CCD 8.
