Title: Explosion generator
Inventor: MIYAMOTO MASAHIRO
IPC: H02N11/00
Filed: 1993-05-31
Abstract: PURPOSE:To provide a small explosion generator with a plasma discharge tube made of materials resistant to a plasma flow, in which a generator part amplifies a current in a way that a magnetic field of pulse current in the plasma flow is produced by exploding an explosive and condensed with another explosive force mechanically. CONSTITUTION:A field generated by a pair of electrodes 6A and 6B is applied to a plasma flow 5 produced by exploding an explosive 3 with a triggering device 4 to produce a pulse current. An explosive 30 is exploded with a triggering device 40 so that the field that generates the pulse current is compressed mechanically. Then, the current is amplified by second generator parts 50, each made up of an armature 31 and a stator 32, and the power is supplied to a load 8. These second generator parts 50 are provided radially around a plasma discharge tube 160 of the plasma flow 5. The plasma discharge tube 160 is made of non-magnetic material like stainless steel that is resistant to the plasma flow. Consequently, the second generator part 50 can be put nearer to the discharge tube 160 and the system can be made small.

Title: Simultaneous rotation control device of cooling fan and water supply pump by water temperature response in internal-combustion engine
Inventor: SATOU NAOSHI
IPC: F16D35/02
Filed: 1983-07-15
Abstract: PURPOSE:To decrease the horsepower consumption, and improve the warming up performance of an engine by preventing of suppercooling by a method wherein a temperature sensing body is provided for the simultaneous controlling of the rotary speed of a fan and an impeller with a cooling water temperature response type fluid coupling. CONSTITUTION:At the operation of an engine, a rotor 15 at the driving part side is rotated via a pulley 4. In case of the low temperature of a cooling water, a piston 9a is deviated toward the right direction with a temperature sensing body 9, then a valve 16 closes an inflow adjusting hole 12a with a spring 17. Therefore, an oil in a transferring chamber 14 is flowed through a circulating passage 19 communicated to an oil reservoir chamber 13 side via a dam 18 by the centrifugal force due to the rotation of the rotor 15, thus, the pumping action is generated by the flowing oil. The oil volume in the transferring chamber 14 is decreased, the rotation of a cooling fan 6 at the driven side and an impeller 7 is slowed down. On the other hand, as the cooling water temperature is raised, the rotation of the cooling fan 6 and the impeller 7 is increased due to the inverse action described above, an air flow is made to be blown and the cooling water is made to be circulated satisfactory by the engine.

The loss spectrum of attenuations corresponding to respective wavelengths one by one is set to an optical filter by repeatingly performing the above described operation while varying the wavelength of the probe light.

Title: Positional control device of roll feeder with mark on plate
Inventor: SUZUKI TOSHIHIKO
IPC: B21D43/00
Filed: 1996-04-25
Abstract: PROBLEM TO BE SOLVED: To secure the feeding accuracy of a plate and to enable the feeding of the plate in a short time by directly detecting the position of the plate on the way of feeding with a mark sensor and controlling a servo motor under consideration of slipping to the remained necessary feeding quantity. SOLUTION: The plate 11 is interposed with the rolls 8, 9 in a roll feeder and the roll 8 is driven with the servo motor 7 to feed the plate 11. A control device of the roll feeder 1 drives the servo motor 7 based on a target feeding quantity stored in a storing means at the time of obtaining a feeding start signal from a pressing machine 3. When a first mark sensor 5 detects the mark 11A arranged on the plate 11, a value of the remained target feeding quantity stored in the storing means is inputted into a counter for the servo motor 7 arranged in the control device to drive the servo motor 7. At the time of obtaining the detected signal with the control device by detecting a mark 11A on the plate 11 with a second mark sensor 6, the servo motor 7 is stopped to complete the feeding of the plate 11.

Title: Check control unit of molten metal in electromagnetic pump type automatic pouring machine
Inventor: TAKAKADO YUUZOU
IPC: B22D37/00
Filed: 1978-10-19
Abstract: PURPOSE: To let the thrust force of an electromagnetic pump always balance with the static pressure of molten metal and check the same and make the time required for tapping constant by detecting the molten metal level in a vessel.  
     CONSTITUTION: When the molten metal level in a vessel 1 is maximum, the output of a load cell 4 becomes maximum as well and the output of a check voltage setting function generator 9 becomes maximum as well. As a result, an electromagnetic pump 3 prevents the effluence of molten metal by overcoming the static pressure of the molten metal level owing to the action of an absolute value circuit 11. Next, when the level of the molten metal decreases, the output of the load cell 4 decreases as well and the output of the foregoing function generator 9 decreases as well. The output of the absolute value circuit 11 then decreases, resulting in the decreased check thrust of the electromagnetic pump 3. Hence, the check thrust of the electromagnetic pump 3 is balanced with the static pressure accompanying the molten metal level, whereby reverse flow is prevented. At the same time the prevention of reverse flowing is also accomplished by keeping the molten metal amount in the electromagnetic pump 3 always constant and therefore the time for the molten metal to begin to come out is made always constant at the pouring.

The leg part 3 of the footrest fixture is embedded in the concrete of the manhole, and multiple footrest fixtures provided in the vertical direction of the manhole is utilized for climbing up and down.  Consequently, the feet of a climber hardly slip off the footrest parts at the time of utilizing the footrest fixtures for climbing up and down, and the climber can naturally hold the footrest fixtures upper by several steps in his/her hands to stably climb up and down.

Title: Reaction spike tire
Inventor: TAKAHASHI HIDEO
IPC: B60C11/16
Filed: 1987-05-26
Abstract: PURPOSE:To prevent the road breakage by installing an elastic rubber whose hardness is varied by the temperature variation behind a spike and allowing said spike to appear and disappear by burying said spike onto the outer surface of the tire. CONSTITUTION:A spike 2 is inserted in slidable ways into a guide 3, and the spike 2 fitted with rubber 1 at the innermost part is press-fitted into a tire 4. With such constitution, the spike 2 collapses the rubber 1 with the revolution of the tire and appears and disappears into the tire 4. When the temperature lowers, the deformation of the rubber 1 by the spike 2 through the hardening of the rubber 1 is reduced, and the spike function is developed. When temperature rises, the rubber 1 is softened, and the spike 2 appears and disappears into the tire 4, and a common tire is formed. Therefore, the dust nuisance can be prevented.

IPC: G11B7/24097
Filed: 1993-05-31
Abstract: PURPOSE:To provide a recording and reproducing system with high density recording for a disk by letting the thickness of corresponding to the clamping area on an optical disk substrate be thicker than a clamping area corresponding to an optical recording area. CONSTITUTION:The optical recording area R and the clamping area C are provided, and a recording part 2 in which, for example, a magnetic layer or a magneto-optical recording layer, or a recording area consisting of irregularity in accordance with information is formed at the optical recording area R, and a hub 3 is mounted on the clamping area C. The thickness of a transparent substrate for the optical recording area R transmitted by a laser beam actually when recording/reproduction is performed is formed thinly, and that of the transparent substrate for the clamping area C not transmitted by the laser beam is thickened than the thickness of the optical recording area R. Since the thickness of the transparent substrate for the optical recording area R is thinned in such a way, a ratio to increase aberration due to the inclination of the disk can be reduced, and also, since the thickness of the transparent substrate for the clamping area C is thickened, strength can be added and deformation can be evaded.

Abstract: PURPOSE:To eliminate the influence of a voltage drop across the Shottky barrier diode of a matching part by not outputting a backup voltage directly through the Shottky barrier diode. CONSTITUTION:The voltage of a subordinate battery 3 selected by a connection switching part 7 is inputted to a voltage control circuit 10.
