Title: Manufacture of semiconductor device
Inventor: NARUSE KAZUFUMI
IPC: H01L21/331
Filed: 1990-02-02
Abstract: PURPOSE:To enable preventing a defective withstand pressure between collector and emitter, even if a shallow intrinsic base region is formed, by forming a link base region connecting the intrinsic base region and an external base region. CONSTITUTION:Patterning of a base region is conducted, an oxide film 2 is etched, the oxide film 2 is grown in the opening of the base region, a nitride film 3 is deposited continuously to the growth of the oxide film, and thereafter the nitride film 3 and oxide film 2 of the part other than the emitter region are subjected to wet etching by the use of hydrofluoric acid according to an emitter pattern. In this case, the oxide film 2 is subjected to overetching so as to be formed into a shape smaller than that of the nitride film 3 on the top of the oxide film. Then, BF2 is ion-implanted while the two-layer film of the nitride film 3 and oxide film 2 left in the opening is used as a mask so that an external base region 8 is formed. Subsequently, <11>B<+>(boron) is ion- implanted to form a link base region 9. In this case, the impurities pass through the visored part of the nitride film 3 and are introduced into the substrate and not injected into the lower substrate of the left oxide film 2.

Filed: 1989-02-02
Abstract: PURPOSE:To avoid the fluctuation of a composite output voltage by a method wherein comparators which judges whether fuses are cut off or not are provided. CONSTITUTION:A comparator group 9 composed of the same number of comparators as the number of fuses in a fuse group 8 is provided between a switch group 4 and respective points A. The (+) input terminals of the respective comparators in the comparator group 9 are connected to the respective points A. One of resistors in a resistor group 7 is connected to a reference resistor 10 whose one end is grounded and is used as the (-) input terminal of the comparator. The resistance of the fuse before cutting-off in the fuse group 8 is denoted by (r) and the resistance of the fuse after cutting-off is denoted by (r'). Further, the resistance of the reference resistor 10 is denoted by R. R is a little larger than (r) and large enough for the respective comparators in the comparator group 9 to judge IR>Ir for a current I. After the fuse is cut off, as r'>>R, the potential of the point A becomes higher than the potential of the point B, so that the output of the comparator is turned to 'H'.

Filed: 1982-02-18
Abstract: PURPOSE:To perform linear plane scanning of the reconstructed image on an imaging plane by making the incident angle of reference light to a hologram in the stage of recording and the incident angle of reconstruction light according to the rotation of a hologram disc different. CONSTITUTION:Convergent spherical waves are used as object light O and divergent spherical waves are used as reference light R in the stage of recording. Scattering spherical waves of a small luminous flux are irradiated as reconstruction light (r) from the same position as the position of the right R in the stage of reconstruction. When the hologram rotates to the position of a broken line H2 from the position of a solid line H1, the light (r) is irradiated on the area C2 at one end of a hologram 3. The light source 20 for the right (r) is so arranged as to irradiate the hologram from the same position as the position of a light source for the light R which is the recording light. The reconstructed image is formed at the point S2 of an imaging plane 4 by selecting said position in a prescribed position, whereby linear plane scanning is accomplished.

Title: Noise suppressor
Inventor: KIMURA KENJI
IPC: G11B20/02
Filed: 1980-02-29
Abstract: PURPOSE:To ensure a free variation of the suppressing effect of noise, by adding a bias varying means to a transistor circuit for suppression of noise. CONSTITUTION:The input signal is divided into the low-and high-band components through the low-and high-pass filters 12 and 13. The low band component is applied directly to the mixer 14, and the high-band component is applied to the same mixer 14 via the noise suppressing circuit 15. The circuit 15 consists of the bias control circuit comprising the transistors 18 and 19, resistances 20 and 21 plus the variable resistance 23. The base bias voltage of the transistors 18 and 19 is varied by changing the resistance value of the resistance 23. Thus the cut-off region is varied for the transistors 18 and 19. In such way, the noise suppressed region can be varied.

Title: Draft control in draft furnace
Inventor: SHIBUYA TEIJI
IPC: C21B5/00
Filed: 1978-03-08
Abstract: PURPOSE: When blast furnace is changed, separate system bypass pipe branched from the main pipe is used to send compressed air, thereby to effect stabilized blast feed.  
     CONSTITUTION: For blast furnace change, compressed air bypass pipe 3 is branched from the main blast pipe 1 at upstream of gas meter A. When the blast furnace operation is changed from No.1 HS and No.2 HS to No.2 HS and No.3 HS, it is  necessary to preliminarily pressurize No.3 HS before changing operation. To do so,  the pressure valve of the bypass pipe 3 is opened. The required amount of air reduces the flow through the meter A, which is automatically adjusted by the measurement A, adjuster control and subsequent blade regulation of the blower BL.  Soon normal blast resumes. When No.3 HS pressurization is complete, No.1 HS is  stopped, and at the same time No.3 HS is blasted.

Filed: 1982-02-19
Abstract: PURPOSE:To find various types of characteristics values of a piezo-electric vibrator  without intentional changing of frequency, by a method wherein a drive source is  caused to serve as an oscillator brought into a practical use, and a parallel electrostatic capacity and a series resonnance frequency measure an aperation frequency and a vibrator terminal impedance of a piezo-electric vibrator which are preliminarily and separately found, whereafter from said factors a nondimentional frequency and a figure of  merit are measured. CONSTITUTION:Through combination of a known piezo-electric vibrator, a parallel electrostatic capacity and a series resonnance frequency measure an operation frequency and a vibrator terminal impedance. From the obtained factors, a zero-dimentional frequency and a figure of merit are computed to lead out a motional impedance  of a piezo-electric vibrator. As noted, without changing of a frequency, characteristics  value corresponding to a given load condition and amplitude can be found. Meanwhile,  in an ultrasonic welding, a mechanical load changes by heating and deformation as a  preceding one exercises the influence on a following one in terms of a time, and thereby the employment of the methof permits catching of a real phase by carrying out a  real time measurement of a frequency and a vibrator impedance.
