Title: Schottky barrier layer type semiconductor device and its preparation
Inventor: OOSAWA SHIGERU
IPC: H01L29/47
Filed: 1978-11-15
Abstract: PURPOSE: To obtain the value of a barrier layer original in platinum silicide in excellent producibility, and to prevent the drop of resisting pressure, by obviating the exposure of an Si substrate by reason of the etching of an impurities film by covering the substrate with a platinum silicide film and an Si 3 N 4  film.  
     CONSTITUTION: An n epitaxial layer 12 is mounted to an n + -type Si substrate 11, SiO 2  13, Si 3 N 4  14 and SiO 2  15 are laminated and the layer 12 is exposed by opening a window. When Pt 16 is formed in a shape that is thicker than the SiO 2  layer 13, and a platinum silicide film 17 is manufactured by sintering the whole in vacuum, an impurities layer 18 is produced on the film 17. The Pt on the SiO 2  film 15 does not change. The Pt, which does not react yet, on the SiO 2  film 15 is selectively removed using the impurities layer 18 as a mask by employing nitrohydrochloric acid, and the layer 18 is eliminated by an HF liquid. The substrate is not exposed by reason of the etching of the impurities layer 18 because the SiO 2  film 13 is coated with the Si 3 N 4  film 14 and the platinum silicide film 17 at that time. Thus, a diode with the height of a Schottky barrier layer original in platinum silicide is obtained even after making up an electrode 19.

Title: High carbon steel excellent in hardenability at low-temperature short-time heating
Inventor: FUJITA TAKESHI
IPC: C21D8/02
Filed: 1997-05-29
Abstract: PROBLEM TO BE SOLVED: To uniformly promote the entering into solid solution of carbides in the course of heating and holding even in the case of heating at extremely low temp. for extremely short time and to obtain a high carbon steel having stable and excellent hardenability by specifying the average grain size and grain size distribution of carbides in a high carbon steel of specific C content, respectively. SOLUTION: In a high carbon steel which has a composition containing, by weight, >=0.2%, preferably <= about 2.0%, of C and preferably containing <= about 2% Mn, <=about 2% Si, <= about 0.03% P, <= about 0.03% S, <= about 0.08% Al, <= about 0.01% N, etc., the average grain size of carbides in its steel structure is regulated to <=0.9 μm and carbides having <=1.1 μm grain size comprise >=80%, and further, the maximum grain size of carbides is regulated to 1.4 μm. This steel structure can be obtained by hot-rolling a slab of prescribed composition at <= about 1200 deg.C, finishing hot rolling at a temp. not lower than the Ar3 point, coiling the resultant rolled steel at <= about 650 deg.C, and performing annealing at <= about Ac3 -30 deg.C.  By this method, the carbides can be allowed to enter into solid solution rapidly and uniformly by means of hardening at <=750 deg.C for about 10 sec, and desired hardness can be stably obtained.

Title: Internal-combustion engine
Inventor: ONDA TAKAMASA
IPC: F02B75/06
Filed: 1984-07-06
Abstract: PURPOSE:To prevent an engine from lowering its output power due to vibration in the X-axis direction and its slide resistance, by providing a pair of connecting rods coupled to a piston and a pair of main and counter crankshafts which are coupled to the pair of connecting rods and the rotating centers of which are arranged symmetrical with the center line of the cylinder. CONSTITUTION:When a piston 21 reciprocates in the axial direction of a cylinder 20 or the Y-axis direction, a main crankshaft 24 and a web 28 rotate counterclockwise while a counter crankshaft 25 and a web 29 rotate clockwise. In this arrangement both crankshafts 24, 25 are synchronized with each other, and their positions become symmetrical with each other with respect to a center axis A-A1 so that connecting rods 22, 23 move symmetrical with the center axis A-A1. As a result, a force acting upon piston 21 is distributed equally to the connecting rods 22, 23 in symmetrical directions so that a load only in the Y-axis direction is exerted to the piston 21 and no side thrust force in the X- axis direction is effected. Accordingly, the slide resistance may be neglected, and vibration in the X-axis direction may be restrained.

Title: Switch device for starter
Inventor: SAKAYANAGI MORIKAZU
IPC: F02N15/00
Filed: 1986-06-17
Abstract: PURPOSE:To make overall size of a magnet switch smaller by transmitting revolution of a rotary shaft of a motor from a rotary body to a groove of a shaft and moving the shaft in the axial direction to move a pinion. CONSTITUTION:With a starter switch turned on, an armature 6 is energized via a brush 9 of a magnet switch 1 and a rotary shaft 5 is turned with a magnet 8 to transmit its rotation to a sun gear 5d, a planetary gear 16 and a rotary body 17. While a shaft 21 engaging with a groove 17a of the rotary body 17 is forced to turn together with the rotary body, the shaft 21 cannot turn as it is stopped with a projection 31a of a bearing 31 and moves in the axial direction. And at the same time with the movement of the shaft 21 to the side of fixed contact points 26 and 27, a pinion engages with a ring gear due to the turn of a lever. And when the engagement becomes deep enough, a movable contact point 24 comes into contact with the fixed contact points 26 and 27 to drive a starter motor to be turned for starting. Thus, since only a length in the direction of the motor shaft is required, an overall size of the magnet switch can be made smaller.

IPC: B21D26/033
Filed: 1984-07-06
Abstract: PURPOSE:To prevent buckling, etc. of a bland pipe at the time of working by inserting a mandrel into the blank pipe, and thereafter, holding the inside of the blank pipe by plural claws, and also presssing an ''O''-ring, and pressure-welding it to the inside surface of the blank pipe. CONSTITUTION:A mandrel body 1 slides in the axial direction by a cylinder A, and a lever 2 is made freely oscillatable by a fluid cylinder 6 through a pin 3 of the outside periphery of a body 1. When the mandrel body 1 is advanced by an operation of the cylinder A, a core shaft 4 is held by a metallic mold C together with a body claw member 7 and inserted into a blank pipe B. Subsequently, when the core shaft 4 is moved backward by the cylinder 6, the claw member 7 holds firmly the blank pipe B from the inside through a tapered diameter expanding part 4b. In this case, an ''O''-ring 10 is deformed in the axial direction by an action of a collar 9, bulged in the diameter direction, abuts on the inside surface of the blank pipe B and seals it. Accordingly, in case of the bulging, the blank pipe B is prevented from contraction and buckling.

Abstract: PURPOSE:To make the outside diameter of the rolled pipe to meet the aimed value uniformly, properly, and quickly, by removing the deviation of the outside diameter of the rolled pipe from the aimed outside diameter, caused by such primary factor as the imperfection of initial set value for the rolling reduction, etc. CONSTITUTION:Assume that the rolling reduction S1-S7 of the stands No. 1-7 in the sizing mill 2 are settled on the relation S1>=S2>=...S6>=S7. Under this condition, under this condition, the outside diameter of the rolled pipe is measured; if there exists some deviation DELTA d between the measured outside diametr and the aimed value, the correction (that is to say-DELTAd) must be given to the rolling reduction in each stand so as to cancel this deviation DELTAd before entering into next rolling pass for the pipe. First of these seven stands, the rolling reduction of the final stand No. 7 is corrected. If the quantity of correction of rolling reduction necessary for correcting the deviation DELTAd of the out- side diameter is taken as DELTAS7, the relation DELTAS7=C- DELTAd must be satisfied, and the rolling-reduction-control-output newly given by the computer/controller 5 must be given by S'7=S7-DELTAS7. After next rolling pass for the pipe under thus correctes conditions, if some deviation is again found, the similar computationis carried out for correcting the rolling reduction in the next pass.
