Title: Magnetic recording and reproducing device
Inventor: YATOMI TOSHIYA
IPC: G11B15/46
Filed: 1990-06-28
Abstract: PURPOSE:To enable the stable traveling of magnetic tape at a prescribed speed and tension at the time of traveling in both foward direction and reverse direction by controlling a driving motor for a take-up side reel with a control signal of a speed detecting means and controlling a driving motor for a feed-out side reel with a control signal of a supply reel side and takep-up side tension detecting means. CONSTITUTION:The driving motor 18 for the take-up side reel T under traveling is controlled with the control signal obtained by comparing a reference value with a speed signal detected by the speed detecting means 7 and 8 by changing a control signal with control signal switches R1 and R2 when the mganetic tape 2 is under traveling in both forward direction and reverse direction, and the driving motor 17 for the feed-out side reel S under traveling is controlled with a control signal obtained by comparing a reference value with such a value that a tension detecting value of the supply reel S side tension detecting means 3 and 6 and a tension detecting value of the take-up reel T side tension detecing means 4 and 5 are multiplied by a coefft. respectively and added up together. Consequently, the prescribed tension is given to the magnetic tape 2, which can be kept in stable contact with a magnetic drum head 1 at the prescribed speed. By this method, the stable magnetic tape traveling is performed.

Title: Rotary machine
Inventor: TAKESHITA JIYUNICHIROU
IPC: F04C2/30
Filed: 1979-12-26
Abstract: PURPOSE: To arrange so that a high pump pressure may be maintained even at time of low rotation by effecting a contact of the external circumferential surface of a cylindrical member provided at the center of a rotor with a sliding member and the pressing of the sliding member against a diametrical direction.  
     CONSTITUTION: If a rotor 22 rotated in an arrow direction, the external circumferential surface of a cylindrical member 34 provided at the center of the rotor 22 shifts in the direction of a discharge port 18, pressing a sliding member 28 against the internal circumferential surface of a cylindrical cavity 14. As a result, the volume of a pump chamber 30 expands, resulting in the suction of a liquid from a suction port 16 and the discharing of the said liquid from a discharge port 18. In addition, if a high-pressure liquid is supplied from the suction port 16 and is discharged from the discharge port 18, the rotor 22 rotates in an arrow direction and functions as a liquid-pressure motor. Under this constitution, the cylindrical member 34 always presses the sliding member 28 against the internal circumferential surface of the cylindrical cavity 14 by mechanical force, so that a pump pressure can be maintained at a high level even at time of low rotation.

Title: Trouble detecting system
Inventor: KURODA YASUO
IPC: B65H7/06
Filed: 1979-12-24
Abstract: PURPOSE: To transport a sheetlike copy automatically by a method wherein the trouble in a detector detecting the presence of the sheet is detected by the pulse counting of a counter.  
     CONSTITUTION: When a start switch 30 is operated to begin the transportation of the copy, and a detector 16 is put in a condition of "ON" in spite of absence of the copy at the detecting position of the first detector 16, a signal is outputted from the detector 16 to open an AND gate A2 if the counted value of a first counter C1 is smaller than a preset value L. A driving roller is stopped by this output signal. On the other hand, a flip flop F3 is set by the output signal of the AND gate A2 and a trouble indicator 33 indicates the trouble. The condition of a trouble in the second detector 17 may be indicated in the same operation.

Inventor: HINO HIROBUMI
IPC: H05G1/34
Filed: 1981-10-23
Abstract: PURPOSE:To permit the voltage applied to an X-ray tube and the current flow to maintain each peak value on starting by detecting the peak value of the bulb current and setting said peak value as a standard signal, and controlling the output voltage of a filament power supply circuit so that the detected value of the bulb current becomes equal to the standard signal. CONSTITUTION:In a set voltage generator 14, the conduction width of a chopper circuit 8 is controlled so that the output voltage may be so set as enabling the filament current corresponding to the bulb current and the bulb voltage which are set in an inverter circuit 11 to be supplied. When an X-ray exposure instruction 60 is given, a high voltage is applied to an X-ray tube 5, and a current begins to flow. A sample holding signal 52 is output until the bulb current wave form 61 is completely erected after turning ON a power supply. A bulb current standard signal generator 17 outputs the max. value of the bulb current signal during the period in which the sample holding signal 52 is input, as a bulb current standard signal 53 into a conduction width controller 13, and said max. value is compared with a bulb current signal 54, and then the conduction width of the chipper circuit 8 is controlled so that the difference in the above comparison disappears.

Filed: 1987-07-07
Abstract: PURPOSE:To improve CN ratio and production efficiency and to reduce cost by molding and storing a resin in an inert gaseous resin, thereby forming a resin substrate. CONSTITUTION:The resin disk substrate with guide grooves is formed by a vent type injection molding machine in an Ar atmosphere chamber. The resin charged into the molding machine is increased in free volume and is compressed and expanded by the screw, by which the resin is efficiently degassed. After the molded substrate is stored for 30hr in the Ar atmosphere, a dielectric layer, recording layer, etc., are formed thereon without exposing the substrate into the atm. The CN ratio is, therefore, increased even by short-time evacuation or long-time evacuation and the production efficiency is improved by the gas substitution during the injection molding, by which the cost is reduced.

Abstract: PURPOSE:To efficiently utilize secondary combustion heat by incorporating Cr2O3 into molten slag to increase the viscosity thereof and injecting gas or powder to bring the slag into contact with the secondary combustion zone at the time of reducing iron ore directly with a reducing agent and producing the molten iron in a smelting and reducing reaction furnace. CONSTITUTION:The Cr2O3 is incorporated at 3-10wt% concn. into the molten slag to decrease the flowability of the molten slag formed simultaneously at the time of charging the iron ore, carbonaceous material as the reducing agent and fuel and slag forming agent into the smelting and reducing reaction furnace and producing the molten iron by melting and reducing the iron ore. The gas and powder are ejected from spiral nozzles shifted from the central longitudinal axis of the reaction furnace on the side of the furnace wall lower than the level of the molten iron into the molten slag to bring the splashes of the slag into contact with the secondary combustion zone. The heat thereof is thereby absorbed and applied to the molten iron. Since the molten slag has a high viscosity, the dissipation of the slag splashes to the outside of the reaction furnace and the consequent decrease of the secondary combustion heat by the slag are prevented.
