IPC: B60C15/00
Filed: 1983-08-06
Abstract: PURPOSE:To improve durability in a bead part, by covering a reinforcing layer's rolled-in end with a covering layer from the inner side of a tire section, while constituting the rolled-in end so as to be held in between together with a carcass, in case of a radial tire for heavy-duty use such as a motor bus or the like. CONSTITUTION:A rolled-in end 12 of a reinforcing layer 9 is covered with a covering layer 13 selected from an organic textile cord layer, a rubber sheet layer, a compound layer of these rubber sheets, a short fiber webbing rubber sheet layer, a metallic cord layer, etc., while this rolled-in end part 12 is held between the covering layer 13 and a carcass 6 and solidified in one. With this constitution, generation of separation or cracking in these rubber sheets at the rolled-in end 12 of the reinforcing layer 9 is effectively preventable so that durability in a bead part is thus improvable.

Title: Fluidized bed exhaust gas heat exchanger
Inventor: OKADA MASARU
IPC: F28D13/00
Filed: 1988-06-14
Abstract: PURPOSE:To purify exhaust gas, eliminate the necessity of providing an exhaust gas purifying device separately and retrieve heat energy in the exhaust gas by providing a fluidized bed with the function of catalyst. CONSTITUTION:The main body 1 of a heat exchanger is provided with a dispersing plate 1b, having a multitude of exhaust gas flowing ports 1a, at the bottom thereof while a fluidized bed 2, consisting of the particles of refractory having catalystic function, is received in the main body 1. Exhaust gas, flowing into the fluidized bed 2 of the main body 1, is contacted with the particles of refractory having catalystic function upon flowing through the fluidized bed 2 and poisonous substances in the exhaust gas are removed whereby the exhaust gas, purified by the fluidized bed 2, is discharged into atmosphere through an exhaust gas outflow port 1d opened at the upper part of the main body 1. Accordingly, the exhaust gas may be purified without employing any exhaust gas purifying device. On the other hand, cold water, flowing into water tubes 3, effects heat exchange between the fluidized bed 2 whereby heat energy in the exhaust gas may be retrieved in the state of hot-water or the vapor of water.

Title: Inverter circuit
Inventor: DOI YOSHIAKI
IPC: H02M7/538
Filed: 1992-06-05
Abstract: PURPOSE:To realize a single mode external drive control circuit by providing a circuit for short-circuiting rectified output from a control winding provided on the secondary of a conversion transformer through a single switching element(SW) subjected to external PWM control. CONSTITUTION:During ON interval of a SW9, primary winding of a conversion transformer 5 is short-circuited when viewed from a booster inductor U12 and energy is stored therein. During OFF interval of the SW9, any one of SW3 or 4 is turned ON and the energy stored in the U12 is superposed on an input power supply 1 thus boosting primary voltage to be applied on the conversion transformer 5. Increasing ON duty of the SW9 corresponds to elongating concurrent ON interval through PWM control of the ON duty of SW. Output voltage of a rectifying/smoothing circuit 6 can be stabilized by subjecting only SW9 to PWM control. In other words, drive control circuit 12 for SW9 can be realized as a single mode circuit.

Title: Rubber mixing and device therefor
Inventor: TAKAGI HARUYUKI
IPC: B29K21/00
Filed: 1979-11-09
Abstract: PURPOSE: The motion of the ram in the rubber mixture is continuously detected and when the ram comes to a specific level, an oil is fed or the ram pressure is changed, thus increasing the dispersion and removing the fluctuation among batches.  
     CONSTITUTION: Ram 9 is lifted to the upper dead point and the rubber materials and carbon black are fed from inlets 6 and 7 respectively. After the inlets are closed, the ram 9 is made to go down so that an appropriate pressure is applied to the rubber materials. Under this condition, rotor 3 is made to rotate to effect mixing. The ram 9 is lifted by the appearent volume increase caused by the crush of the starting materials until it balances with the pressure at point P, then it begins to come down as mixing proceeds. This motion of the ram 9 is taken out as an electric signals from sensor 14 generated by the motion of a permanent maget 13 on the tellurium rod 12 and the power from filter 24 is compared with the level set 26 in the comparison part 27. When the power from filter 24 coincides with the ram level H when the oil should be fed, a signal is sent out of the comparison part 27 to feed oil from nozzle 28.

Title: Disk sound recording system
Inventor: POORU KUIN
IPC: G11B27/10
Filed: 1993-05-25
Abstract: PURPOSE:To record voice data having no insufficient section by writing input data to a RAM, reading recorded data after timing, when data reach a fixed value or more, and recording the recorded data on a disc. CONSTITUTION:Input data are written in a RAM 4 by operating a DET/REC button 15. When a signal detector 5 detects timing, when the level of the input data reaches a fixed value or more, data are read through a memory controller 3 from the RAM 4 and data are transmitted over an EFM encoder/decoder 6. Data are written to a disk 13. Consequently, data are not transferred from the RAM 4 to the disc 13 until the detector 5 detects an input voice signal and transmits the signal to a computer 7. Accordingly, data written after timing, when a voice was input from the RAM, are read and recorded, thus recording voice data having no insufficient section.
