Abstract: PURPOSE:To cause the direction of an article at a rear end to vary at a front end simultaneously with conveyance of the article from the rear end to the front end by providing the given number of wheels around which an endless belt having a rack to the end of which is pivotally mounted thereon through a vertical pin is run. CONSTITUTION:When a horizontal rotary table 8 is moved to a rear end, an article is transferred to the horizontal rotary table 8 by means of a robot. In a state that the horizontal rotary table 8 is moved to a rear end, an endless belt 12 part to which a vertical pin 11 is located is located on the right side. When an article is placed on the horizontal rotary table 8 and an endless belt 12 is driven in the direction of an arrow mark A, a rack 10 and in turn the horizontal rotary table 8 having no play in a longitudinal direction is slid forward. An endless belt 12 part to which the vertical pin 11 is located is separated away from a right wheel 13 at the front end. When the endless belt is brought into a state to move completely in a lateral direction, the forward movement of the horizontal rotary table 8 is stopped. After the article on the horizontal rotary table 8 is carried out, the endless belt 12 is reversed and the horizontal rotary table 8 is returned to a rear end.

Abstract: PURPOSE:To prevent production of vibration of an internal combustion engine and to decrease the size of a device, by a method wherein the one end of a power transmission shaft, provided at both ends with joints allowing relative declination, is connected to the output shaft of the internal combustion engine through the joint, and the other end is connected to a hollow shaft through the joint. CONSTITUTION:Deviation of an internal combustion engine is reduced by means of resilient joints 27 and 28 allowing a relative declination located to both end parts 26a and 26b of a power transmission shaft 26. Vibration of the internal combustion engine is absorbed by setting a power transmission shaft 26 to a relatively high value and by connecting the shaft through the resilient joints 287 and 28 allowing relative declination. A pulley, outputting a rotation force to a generator, is secured to a hollow shaft 21, and is located between the resilient joints 27 and 28 located to both end parts of the power transmission shaft 26. The length in an axial direction of a transmission shaft 11 is decreased by a distance equal to the length by which the pulley is prevented from being extended outwardly of the resilient joint 28. This enables decrease of the size of a device.

Filed: 1988-02-19
Abstract: PURPOSE:To lower a temperature around a gap part and to obtain the magnetic head of a satisfactory high density recording and reproducing characteristic by providing a cooling body, which is composed of a Peltier element, on the both side surfaces of the gap part in a magnetic head core. CONSTITUTION:A coil is wound to a magnetic head core 2, which forms a gap 1, and a cooling body 3 is formed on the both side surfaces of the gap 1. The cooling body 3 is composed of the Peltier element and an endothermic part 4 is joined. Then, a radiating board 6 is provided in a radiating part 5 of the element 3. When a current flows to the element 3, heat around the gap 1 of the core 2 is made endothermic by the endothermic part 4 and the temperature goes to be low. Since the saturation magnetic flux density of magnetic materials is higher at the lower temperature, the high saturation magnetic flux density is held by cooling the surrounding of the gap. Thus, the magnetic head of the satisfactory high density recording and reproducing characteristic can be obtained.

Abstract: PURPOSE:To attain simple temperature compensation by converting a result being the multiplication between an output squaring an analog signal of a temperature detection circuit and the analog signal itself into a voltage change at a voltage extracting point and applying it to a varactor diode of a crystal oscillation circuit. CONSTITUTION:An analog value of a temperature detected by a temperature sensor of a temperature detection circuit 1 is squared by the 1st multiplication circuit 2 to make a quadratic function. Moreover, the output of the temperature detection circuit 1 is multiplied with the quadratic function by the 2nd multiplication circuit 3 to form a cubic function. Then a converting circuit 4 converts the cubic function into a voltage change at a voltage extracting point to form a compensation voltage generating circuit 5. The compensated voltage generated by the compensation voltage generating circuit section 5 is fed to the varactor diode 8 of the crystal oscillation circuit 6. Thus, the temperature characteristic as a cubic function provided substantially to the crystal is compensated and the frequency deviation is kept within + or -2ppm over a wide temperature range.

Title: Rolling method for water cooled unsolidified killed steel ingot
Inventor: NASHIKAZU HAJIME
IPC: B21B1/02
Filed: 1979-03-30
Abstract: PURPOSE:To fill up the cavity with metal, and to improve the yield, by performing the blooming pass on the rapped, unheated ingot whose internals involve still unsolidified parts. CONSTITUTION:Directly following to completion of the pouring, the water is spread to cool the outside surface of the ingot. By this water cooling, the outside surface of the ingot begins to solidify at low speed; at the point when the outside surface is sufficiently solidified, the ingot is rapped out of the mold. This ingot is successively put into the unheating insulation furnace is which the ingot is kept to wait for the restoration of the surface temperature. Through this waiting period, the temperature of outside skin of the ingot is gradually heightened depending on the thermal conduction from the internal unsolidified high temperature zome; when the surface temperature of the ingot becomes the blooming temperature after a specified period of time for restoring the temperature, the ingot is extracted from the insulation furnace, and is fed into the blooming pass. This blooming pass is performed under the condition of the ingot whose internals involve still unsolidified parts. According to this method, the heat capacity of the molten steel itself is utilized effectively to unnecessitate the reheating, and the heat energy is greatly saved.
