Title: Water-cooled jacket for furnace bottom electrode of dc electric furnace
Inventor: KATO TOSHIO
IPC: H05B7/12
Filed: 1994-02-17
Abstract: PURPOSE:To improve a water-cooling effect, and lengthen the service life of an electrode by constituting a water-cooled jacket by dividing it into plural parts in the circumferential direction, arranging a step difference on a contact plane of respective parts, and elastically joining divided parts to each other. CONSTITUTION:A water-cooled jacket 6 is constituted by dividing it, for example, into two parts in the circumferential direction. A step difference is arranged on a contact plane of divided parts. The divided parts are elastically joined to each other by a bolt 13 and a nut 14, for example, through a coil spring 12. In an example of a 100t DC electric furnace for melting production of medium carbon high manganese steel, a furnace bottom electrode 3 composed of round bar steel has an outside diameter of about 300mm, and a height of the water-cooled jacket 6 surrounding this lower end is about 1000mm, and a thickness is about 100mm. Since a step difference of 20mm is arranged on a contact plane, the water-cooled jacket 6 is kept in an excellent contact condition without creating a clearance to expansion and contraction of the round bar steel by a temperature change reaching the normal temperature from a steel melting temperature of 1630 deg.C, and maintains a watercooling effect.

Title: Wheel slip detector for automobile
Inventor: NAGAOKA MITSURU
IPC: B60R16/02
Filed: 1984-02-06
Abstract: PURPOSE:To ensure the detection of slipping, by detecting the correlation of rotary speeds between driving wheels and idler wheels. CONSTITUTION:Rotary speed detecting means 8 and 9 detect the rotary speeds of a driving wheels and idler wheels, respectively. When the driving wheels are slipped on the road, the rotary speed of the idler wheels does not follow the change in rotary speed of the driving wheels, and the correlation of the rotary speeds between both wheels is collapsed. In an electronic judging circuit 11 of a wheel slip detector A, the fact that the correlation of the rotary speeds, which is computed by a comparing means 20, is different from reference correlation by a judging means 21 is detected. A signal indicating the slipping state of the wheels is outputted from the means 21.

Filed: 1986-01-31
Abstract: PURPOSE:To detect the short circuit of an electronic component by applying a DC voltage which is 10-50 times a rated voltage between the lead terminal of the electronic component sandwiched in a laminate material and a metallic conductor which contacts metallic foil of the laminate material. CONSTITUTION:The aluminum foil 3 is provided between a heat sealing resin sheet 1 and a heat-resisting resin sheet 2 to constitute the three-layered laminate material 5. Plural recessed parts 4 which projects toward the sheet 2 are provided, electric components are put in the recessed part 4, and the laminate material 5 is folded at the intermediate part. The metallic conductor 9 is inserted into the laminate material to contact the aluminum foil 3 and the DC voltage which is 10-50 times the rated voltage is applied from a short-circuit detecting device 11 to between the conductor 9 and the connection body 10 of lead terminals 6 and 7 of the electronic components to perform the short-circuit detection of the individual electronic components by the device 11. In this case, the applied voltage can be set high without reference to the rate voltage of the electronic components, so even if either of the aluminum foil 3 and lead terminals 6 and 7 contact the sheet 1 or are in a defective dielectric strength state, the detection is performed completely, so a short circuit of an electric component is detected reliably.

Title: Spark ignition gas internal combustion engine
Inventor: MORI SHUNICHI
IPC: F02B19/08
Filed: 1991-02-14
Abstract: PURPOSE:To enhance the starting characteristics by setting the air-fuel ratio in an aux. chamber to its theoretical value when the engine is to be started under the low temp. condition. CONSTITUTION:When having judged that the engine 12 is going to start, a controller 34 shuts a solenoid-operated shutoff valve 35 to stop supply of gaseous fuel to an aux. chamber 28 from the aux. chamber fuel supplying pipe 30 side. To this aux. chamber 28, only part of the mixture gas situated in a main combustion chamber 18 and set to the theoretical air-fuel ratio is supplied by rotating the crank shaft 13 of the engine 12. Accordingly the mixture gas with good ignitability situated in the aux. chamber 28 and set to the theoretical air-fuel ratio is ignited with spark discharge of an ignition plug 29 occurring before the end of each compression stroke, and the engine is started by propagating the flames to the mixture gas on the main combustion chamber 18 side. Thus good igniting performance is secured even when the engine 12 is to be started under the low temp. condition.

Title: High-speed reel feed device of magnetic recording and reproducing device
Inventor: BAN ITSUKI
IPC: G11B15/44
Filed: 1983-02-14
Abstract: PURPOSE:To realize a shift to a high-speed feed of a reel with no generation of mechanical noise by using a control circuit which reverses a capstan motor as soon as a lock state of a lever is released. CONSTITUTION:A capstan motor 22 which drives a capstan la is controlled for forward/reverse revolutions by a circuit block 21 including a bridge circuit consisting of four transistors TRs. If a control input of a high level is supplied from a terminal 21a, the motor 22 has forward revolutions. While the motor 22 is reversed with a control input of a low level. When a signal of a low level which commands the quick traverce/queue mode is supplied from a terminal 17a, a TR 19a conducts to energize an energizing coil 15a. Thus the lock state of a lever 3a is released, and a reel 5a is driven to set a quick traverse/queue mode. When the input of the terminal 17a is reset to a high level, the TR 19a is nonconductive. Then the lever 3a is sucked and locked to stop the revolution of the reel 5a.

Filed: 1978-02-27
Abstract: PURPOSE: To prevent revolution of an auxiliary threshold in the case of a maintenance operation and so on, by locating a device which releases a functional relation of a door opending motion and the threshold at a given time.  
     CONSTITUTION: A releasing device 17 is located at a rod 8 placed between a sliding mechanism 5 of a door 2 of a cage 1 and an auxiliary threshold 14 which reduces a space between the cage 1 and platfrom in the case of the door 2 opening. A contact 18 and a switch 19 incorporated in an elevator management unit 20 are open, and an electromagnet 17h of the releasing device 17 is deactivated in the event of a usual operation. A male hook part 17f pushed by an activating substance 17i is hooked into a female hook groove 17c, and thus, a upper rod 8b and a lower rod 8a are united in one body. In the case of the door 2 opening, the rod 8 goes up via a link 7 and a lever 6. A transmitting device 13 thus revolves, and the work revolves upward the auxiliary threshold 14. In consequence, a gap between the cage 1 and the platform is reduced. In the case of a maintenance operation, the contact 18 and switch 19 are closed, and the male hook part 17f parts from a movable head 17b. Thus, even if the door 2 opends, the auxiliary threshold 14 can be prevented from revolving upward, and an accient caused by the upward revolution can be protected.

Abstract: PURPOSE:To prevent a disk from being damaged by constituting it so that a magnet is detached/attached in accordance with the vertical movement of a yoke plate and also the yoke plate is stopped at the position being above a prescribed length by a hook. CONSTITUTION:In the opened state of an opening/closing cover 1, the hook 13c at the tip of a chuck disk 13 is engaged with the yoke plate 14, and the lower surface of the magnet 15 is separated off from the chuck disk 13. So that, a magnetic force of the magnet 15 does not reach to the lower surface of the chuck disk 13. Therefor, the foreign matter of an iron piece such as a clip is not attracted on the lower surface of the chuck disk 13. Consequently, the surface of the disk 7 is never damaged even though the opening/closing cover 1 is closed.
