Inventor: SAKURAI JIYUNJI
IPC: H01L21/74
Filed: 1982-01-29
Abstract: PURPOSE:To form the side face part of a selective epitaxial growin region in high density by a  method wherein, after an ion implantation has been performed from an oblique direction on  the surface of the single crystal semiconductor substrate whereon an insulative layer having  an almost vertical end part is selectively coated, and a single crystal semiconductor layer is  grown on the region of the semiconductor substrate surface having no insulative layer coating. CONSTITUTION:A boronic ion is implanted from an oblique direction on the surface of an Si  substrate. By performing the above implantatin, boron ion is implanted not only in the Si substrate, but also on the side face of a silicon dioxide layer as shown in the diagram b. The direction of inclination of the above implantation is omni-directional, and this can be accomplished by rotating the Si substrate. Also, the energy of implantation is selected in such a manner that the implanted ion will have the largest distribution in the vicinity of the surface  of the substrate, and as for the dosage, 10<12>/cm<2> or 10<13>/cm<2> is considered suitable. On the Si substrate whereon the above-mentioned procedures have been performed, a P type Si layer 14  is epitaxially grown as shown in diagram c. At this time, the boronic ion which was implanted  on the side face of the silicon dioxide layer is diffused on the epitaxially grown region, a high density P type region 15 is formed on the side face of the above region, and, at the same time, a low density P type epitaxially grown region is formed by performing an automatic doping.

Title: Pneumatic radial tire
Inventor: MORIKAWA YASUO
IPC: D02G3/48
Filed: 1989-01-24
Abstract: PURPOSE:To improve high-speed durability by providing a carcass auxiliary layer between a carcass layer and a belt layer so as to form a crossed structure between the carcass layer and auxiliary layer, and arranging auxiliary layer cords in parallel as single monofilaments. CONSTITUTION:Between a carcass layer 4 and a belt layer 5d located at the innermost layer is provided a carcass auxiliary layer 7 which is composed of cords arranged in parallel at approximately 0 degree to the tire circumferential direction EE'. Since the cord angle on the carcass layer 4 is 90 degrees, a crossed structure is formed between the carcass auxiliary layer 7 and the carcass layer 4. Thus, the carcass layer 4 and the carcass auxiliary layer 7 have their main elastic axes at right angles to each other which coincide with the tire sectional direction and circumferential direction, respectively. This arrangement prevents cord angle change during vulcanization, thereby ensuring improved durability when running at high speed.

Title: Rolling mill and rolling method
Inventor: OOKI TAKASHI
IPC: B21B1/36
Filed: 1979-02-09
Abstract: PURPOSE: To lighten the rolling load at rolling the strip, by interposing the center work roll between two outer work rolls, by backing up the center work roll with the backup roll, and by independently driving each of outer work rolls.  
     CONSTITUTION: At rolling the metallic strip 9, the peripheral speed of outer work roll 2 is adjusted by the driver 12 so as to be equal to the linear speed of the strip 9 given by the tension roll 8; the peripheral speed of another outer work roll 2' is adjusted by the driver 12' so as to be a value determined from the thickness ratio of strip 9, 9', respectively before and after the rolling work; hereby, the peripheral speed of outer work roll 2' becomes equal to the linear speed of the strip 9' due to the tension roll 8'. Accordingly, the strip 9 winds round outer work rolls 2, 2', without causing slip. The center work roll 1, and backup rolls 3, 3', receive upward reaction through the strip 9', and the center work roll 1 tends to cause bending; however, since the large diameter backup roll 3' of great rigidity supports the center work roll 1 through the small diameter backup roll 3, the rolling load to be impressed on edges of the strip 9, 9', is lightened, and the edge drop is diminished.

IPC: H02K37/14
Filed: 1985-01-28
Abstract: PURPOSE:To enable to convert the rotary motion of a rotor into a linear motion of an output shaft by slidably passing the output shaft to a bearing for rotatably supporting the output shaft for supporting the rotor. CONSTITUTION:A stepping motor is operated by sequentially switching the excitations of salient poles 12-19 of its stator 2 and a layer of windings 20, 21, the poles of a rotor 1 are magnetically attracted to oppose to the excited layer, and the rotor 1 is rotated at a certain step angle. Whenever the rotor 1 is rotated at one step angle by the magnetic attraction simultaneously upon rotating, the rotor 1 is attracted to the outer periphery, and moved in the same amount as a pitch along the axial direction of the rotor shaft between adjacent poles. Thus, since the rotor 1 axially moves upon rotating, the output shaft 5 for supporting the rotor 1 and slidably passing the bearing is linearly moved.

Abstract: PURPOSE:To provide a pulsed laser power supply with a long lifetime by restricting any damage of the device which might be produced upon erroneous operation of the device by providing means for detecting erroneous operation of a thyration and a switch for controlling a charging circuit. CONSTITUTION:An erroneous operation detector 14 includes a current detector 15 such as a current transformer provided in a discharge circuit of a thyratron 10 for detecting erroneous operation of the thyratron 10. Hereby, the erroneous operation detector 14 takes out an erroneous operation signal in combination with a synchronization signal from a synchronization control device 1. More specifically, if it detects a discharge current not corresponding to a trigger signal from the thyratron 10, it issues an erroneous operation signal. Further, when anode voltage of the thyratron 10 is measured by a voltage divider 16 and further a charging current is measured by a current detector 17, as a result of which the anode voltage does not correspond to charging voltage, i.e., when the charging voltage is not raised even if the charging current flows, an erroneous operation signal is issued. These erroneous operation signal opens a vacuum tube 3 provided in series in a DC power supply 8 to stop in the charging operation. Thereafter, the vacuum tube is closed in synchronism with the signal from the synchronization control device 1 to restart the circuit.
