Title: Production of smashed blast furnace slag sand
Inventor: IIZUKA MOTOHIKO
IPC: C22B7/04
Filed: 1977-12-22
Abstract: PURPOSE: To continuously produce smashed blast furnace slag sand contg. little granular pig iron and little water at a low cost in a simple and rapid manner by screening blast furnace slag and carrying out drying and grain size regulation of the slag at the same time, followed by magnetic separation.  
     CONSTITUTION: Granular blast furnace slag charged into a raw slag hopper from a cart is screened to remove coarse granules. The slag of below a predetermined diameter is charged into rotary drum 10 through slag introduction hopper 18 provided to height side hood 15. The charged slag is housed between ribs 17 at the lower position, carried to the upper position by rotation of drum 10, dropped, hit against heating dryer 11, and housed between ribs 17 again. By repeating the motion the grain size of the slag is regulated by collisions, friction, etc. at the time of dropping until discharge from the system, and the slag is dried at the same time. After discharge, granular pig iron is removed by a magnetic separator to obtain a product.

Title: Receiver
Inventor: MIYOSHI SADAHIRO
IPC: H03J5/02
Filed: 1994-07-05
Abstract: PURPOSE:To facilitate preset by providing a means for erasing a frequency stored in a preset memory from the memory and an invalid frequency setting means for preventing the erased frequency from being stored even when autopreset is executed. CONSTITUTION:When an autopreset switch 20 is operated, autopreset processing is started. The levels of received signals from a tuner part 12 are compared with a previously set reference signal level, and reception frequencies are stored in a preset memory 22 in order from the highest received signal level corresponding to a preset switch 21. Next, overlapped broadcast stations and unwanted broadcasting stations caused by noise or the like are erased by operating an erasing switch 23. A microcomputer 2 moves the erased reception frequency to the other memory and sets it as an invalid frequency. Therefore, even when the autopreset is executed again, the broadcast station at that frequency is not preset. Further, a preferential storage means for preferentially storing the frequency in the preset memory and a canceling means for an invalid station are provided at a priority station.

Title: Valve pin working mechanism for injection molding
Inventor: JIYOBUSUTO URURITSUHI GERAATO
IPC: B29C45/76
Filed: 1981-09-30
Abstract: This invention relates to mechanical double acting mechanism for actuating valve pins in a valve gated injection molding system. A number of valve gate units are aligned with a pneumatically driven toothed rack member. The rack member engages a hollow rotatable pinion member which is secured in each unit against transverse movement. The driven end of the valve pin is fixed in a bushing which extends through the pinion member and threadably engages it. The valve pin is actuated between the open and closed positions by longitudinally driving the rack member which rotates the pinion member and the bushing. In addition to providing a reliable and relatively inexpensive actuating mechanism, provision is made for relative axial adjustment of the valve pins prior to the commencement of operation which provides accurate valve seating without unduly high manufacturing tolerances.

Title: Arm driving device
Inventor: MAEDA TETSUO
IPC: G11B3/36
Filed: 1981-09-28
Abstract: PURPOSE:To realize the complicated transmission function including the nonlinear element in a simple way, and to obtain the stable servo characteristics, by detecting a tracking error angle to feed it to a microcomputer, and then making use of various functions of the microcomputer. CONSTITUTION:A collector current I1 of a transistor TRQ2 of an A/D converter 12 is varied by the voltage generated from a tracking error angle detector 7. A TRQ1 is turned on and off by the pulse signal of a microcomputer 13, and the charging/discharging is repeated for a capacitor C1. As a result, the tracking error angle is produced in the form of the time suring which the collector potential of the TRQ2 reaches the reference voltage. That is, a pulse signal having its pulse duration varied in accordance with the error angle is obtained at the collector of the TRQ2. This pulse signal is fed to the computer 13, and a servo output is obtained to eliminate the error angle. A motor 11 is turned by driving signals 14 and 10 to shift an arm base 4. Then the tracking error is eliminated.
