Title: Studless tire and manufacture thereof
Inventor: ODA KEISHIRO
IPC: B60C11/14
Filed: 1989-04-17
Abstract: PURPOSE:To improve the antislipping performance by dispersing powders or short fibers formed into bar-shaped particles into a tread surface layer with the particles oriented in the direction of thickness of the tread. CONSTITUTION:A rubber composite obtained by mixing a rubber composite for use on the tread of a ordinary tire with steel short fibers about 0.1mm long with average gage of about 0.01mm, and further by blending resorsinformaldehyde condensate and methylolmelamine as bonding agents, is extruded by a tread extruder 1 to form a cylindrical body 2. A rotary knife whose blade width is larger than the wall thickness t of the side wall 3 of the cylindrical body 3 is applied to the cylindrical body at about right angles to the body, and cuts off the body into a helical shape with a pitch d smaller than the wall thickness to form a strip 4 while it moves in the direction of length of the cylinder 2. The plural strips 4 are juxtaposed on the upper surface of a base tread 5 to form a trad surface layer 7. The antislipping performance can be improved by this configuration.

Title: Conveyor
Inventor: NAKADA AKIRA
IPC: B65G35/06
Filed: 1988-04-20
Abstract: PURPOSE:To reduce the height of a conveyor and to enable free start/stop of a pallet, in a work carrying conveyor in assembly line, by arranging a screw shaft in parallel between pallet guide rails and fixing a magnetic block to the pallet side through a gap in the radial direction of the screw shaft. CONSTITUTION:When a screw shaft 3 is rotated in the carrying direction, magnetic blocks 9 facing each other through a gap in the radial direction of thread ridge are attracted to the screw shaft 3 and moved in the carrying direction. On the other hand, a stopper cylinder not shown is lifted and contacted with the pin 10 of a pallet 5 thus stopping the pallet 5. At this time, the pin 10 retracts into a cushion 11 to relieve impact. When the screw shaft 3 rotates to separate the thread ridge from the magnetic block 9, magnetic force weakens to stop the block 9 completely. When the stopper is removed, motion is resumed through magnetic force. By such arrangement, the magnetic block can be started and stopped freely.

Title: Transformer for measuring instrument
Inventor: YONEDA MASATO
IPC: H02H7/04
Filed: 1991-04-26
Abstract: PURPOSE:To control a ferroresonance phenomenon without having an effect on error characteristics of a normally-charged transformer for measuring instrument by connecting a resistance burden to the secondary side of the transformer for measuring instrument only for a period while the ferroresonance phenomenon which occurs with the release of a breaker continues. CONSTITUTION:A ferroresonance waveform which occurs when a breaker is released contains a low-frequency rectangular-wave voltage and a capacitor 2 is charged by a certain voltage part of the rectangular-wave voltage. When a charging voltage of the capacitor 2 comes to the one enough to turn on a thyristor 3, the thyristor 3 starts to conduct. When the thyristor 3 conducts, a resistance burden 4 is connected to a secondary circuit of a transformer for measuring instrument 5. Since a reactance value is so selected by the capacitor as to be small enough compared with a resistance, the thyristor never conducts in the normal operation. Therefore, the characteristics of the normally operated transformer for measuring instrument are not adversely affected. Consequently, the ferroresonance phenomenon can be controlled.

Abstract: PURPOSE:To manufacture multi-kind small quantity molded items at a low cost by a method wherein plastic is injected in a mold, in which breakable mold is used for the mold part coming into contact with product and being backed-up by strong mold and, after the solidification of the plastic, the mold is removed through breaking. CONSTITUTION:Slurry, which is prepared by dissolving hot water gypsum breakable with water, is cast round a wax model 1, which is installed at the center of a frame, so as to shape a mold 2a. By heating the whole assembly up to about 100 deg.C under the state that the mold 2a is turned upside down, the wax model 1 is melted away outside the mold 2a. The resultant mold 2a is fixed in support molds 3a, 3b and 3c. The support molds are installed in the cavity of bisected back-up molds 4a and 4b. Under the above-mentioned state, molten plastic 8 is injected from above in the mold. After the solidification of the plastic, the mold 2a is demolded and immersed in hot water 7 so as to instantly break the hot water breakable gypsum. Thus, when the small quantity production of plastic molded item with complicated shape is intended, item can be molded at a low cost without using metal mold.

Abstract: PURPOSE:To increase the compression rate and the expansion rate by controlling the gain of an AGC amplifier depending on the difference between an output of a detector receiving a logarithmic detection output and an AGC amplifier output, and an output of the logarithmic detector receiving the detector output and the AGC output. CONSTITUTION:The amplitude of an input signal VIN1 at the compression is subjected to logarithmic detection and detected by a detector 13 via an AGC amplifier 11. An error amplifier 14 inputs both detection outputs, outputs a difference signal to control the gain of the amplifier 11 so that both the detection outputs are equal. Thus, the output VOUT1 of the amplifier 11 is compressed logarithmically. The amplitude of an input signal VIN2 is detected by a detector 22 at the expansion and the signal is detected by a logarithmic detector 23 via an AGC amplifier 21. An error amplifier 24 inputs both the detection outputs, outputs a difference signal to control the gain of the amplifier 21 so that both the detection outputs are equal. Thus, the output VOUT2 of the amplifier 21 is subjected to logarithmic expansion.
