Title: Manufacture of semiconductor device
Inventor: SUZUKI WAN
IPC: H01L29/73
Filed: 1989-05-23
Abstract: PURPOSE:To finish an ion-implantation at one time and to simplify the manufacture of a semiconductor device by a method wherein when the collector and the collector lead-out part of a bipolar transistor are simultaneously formed, a mask, which is a CCD oxide film at least partly tapered in its inner edge parts to border on the exposed part of a substrate, is used as a mask in an ion-implantation method. CONSTITUTION:A CVD oxide film 7 is deposited on an Si substrate 1 and P ions are implanted in the whole surface to form a P diffused layer in the film 7. Then, a resist 3 is applied on the peripheral edge part of the film 7 and a wet etching is performed to form an opening in the resist 3. At this time, as an etching rate is high in the vicinity of the surface, which has a high P concentration, of the film 7 as shown by arrows, the lateral etching makes rapid progress, creeps under the resist 3 in the surface of the film 7 and a spherical recessed part is generated. After that, the resist 3 which becomes useless is removed, ions are implanted using the remaining film 7 as a mask to generate isolation regions 8 respectively in the vicinity of the tapered part of the film 7 and in the vicinity of the non-tapered part to oppose to this tapered part and ions are again implanted to form a collector 9 and a collector lead-out part 9'.

Title: Positioning method for glass tube and electrolytic drilling machine
Inventor: KOBORI GIICHI
IPC: B23H3/00
Filed: 1993-05-31
Abstract: PURPOSE:To simply perform positioning of a glass tube with high precision and accuracy by emitting the light from the top end of the glass tube, and adjusting an interval between the top end of the glass tube and an object to be positioned based on the size of an irradiating range in the object to be positioned. CONSTITUTION:The light emitted from the top end of an optical fiber 6 is difficult to disperse because it is not emitted outward by the existence of a light shield membrane 4c. In a spotlight S, the distortion of its shape becomes little because the size of an irradiation range changes with a distance from the glass tube 4. The top end position of a small-diameter part 4b is set by monitoring the size of the spotlight S. The vertical position of the glass tube 4 is fine-adjusted through a lifting arm 8a by the operation of a feed amount fine-adjusting means 8, so it is possible to set a distance between the surface of a material 1 to be processed and the top end of the glass tube 4.

Title: Lateral bend measuring method for steel plate under carriage
Inventor: KOBAYASHI YOSHIHEI
IPC: G01B5/20
Filed: 1978-10-21
Abstract: PURPOSE: To realize the on-line measurement of the lateral bend of the steel plate by measuring the angle formed by the shift amount in both the carriage line direction of the steel plate and its right- angled direction and the straight carriage line connecting the measuring points and then calculating the bend amount.  
     CONSTITUTION: When measuring the bend from point A on side edge 5 of the steel plate to point B, E 1  is set for the point of the side edge where point A passes through point K in lapse of time t 1  after passing installation position K of measuring roller 6. And thus shift amount l 1  of the steel plate in the carriage direction is measured by calculator 16 and based on velocity v of the steel plate and passing time t 1 ; while shift amount w 1  vertical to the carriage direction is measured by calculator 15 respectively. At the same time, angle α formed by the straight line connecting points A and B and the line of the carriage direction can be calculated by obtaining BC of triangle ABC. Accordingly, distance m 1  orthogonal to straight line AB from point E 1  can be calculated by Eq. 1, and the miximum value between A and B of the distance means the bend amount between A and B. In such way, the bend amount of the steel plate can be measured by the on-line method.

Then, all output ports are turned to L, information required for hit recovery is saved in an internal RAM and a standby mode is started. When reset is not attained in the case of hit recovery, the voltage at the point (e) detected by the detector 3 is turned to H and corresponding to the signal NMI, the CPU 8 is recovered from the standby mode to an ordinary operating mode and restarts operation based on the information in the RAM.  When the reset is attained, the CPU 8 detects the voltage of an A/D input port (b) and when it is higher than a threshold value, the CPU judges the hit and restarts the operation based on the information in the RAM.

Filed: 1988-05-26
Abstract: PURPOSE:To increase the attraction force of an armature at the time of excitation and to improve magnetic efficiency by forming a protrusion to be engaged with a recess on one pieces and a connecting piece, and making the inner periphery of the recess approach to the outer periphery of the protrusion so that a magnetic flux produced by the excitation of a coil is made to pass between the inner periphery of the recess and the outer periphery of the protrusion. CONSTITUTION:A recess 12 is formed on one side face 1a of one piece 1, and a protrusion 7b to be engaged with the recess 12 is formed on a connecting piece 7. A magnetic flux flowing at the pieces 1, 7 at the time of the excitation of a coil 5 is branched to the inner periphery 12a of the recess 12 and the outer periphery 7 of the protrusion 7b, and the magnetic flux flowing between the side face 1a of the piece 1 and the side face 7a of the piece 7 is reduced. Since an attraction force between the recess 12 and the protrusion 7b does not affect the influence to the rotation of an armature 9, the reverse rotary force of the armature 9 due to the attraction force between the side face 1a of the piece 1 and the side face 7a of the piece 7 is reduced. Accordingly, the rotary force of the armature 9 due to the composite force of the attraction force operating between the other piece 2 of a yoke 3 and the operation piece 8 of the armature 9 and the attraction force of the piece 7 is increased, and its magnetic efficiency is improved.
