Title: Automatic adjusting circuit of filter
Inventor: HORI KAZUAKI
IPC: H03H11/04
Filed: 1993-06-16
Abstract: PURPOSE:To decrease an adjustment error even when a reference signal containing a higher harmonic component or a crosstalk component is used by eliminating the higher harmonic component contained in the reference signal by an LPF or a BPF, and thereafter, inputting it as a signal source of the automatic adjusting circuit. CONSTITUTION:A signal of a reference signal source 1 is divided into two through a higher harmonic component suppression filter 2, one of them is inputted to a phase comparator 4 through an adjustment filter 3, and the other is inputted directly to the comparator 4. An output of the comparator 4 is smoothed and converted to a cut-off frequency control signal of the filter by a signal converting circuit 5, and negatively fed back to the filter 3 and a filter 6 to be adjusted. As for the filter 3, the cut-off frequency is adjusted so the phase turns by 90 degrees. By controlling the filter 3 or 6 by using the cut-off frequency control signal, automatic adjustment for compensating an element variation in an IC can be realized.

Title: Hermetic sealing method of package for semiconductor devices
Inventor: SUZUKI KATSUHIKO
IPC: B23K11/08
Filed: 1977-12-02
Abstract: PURPOSE: to weld a package which has a seal frame having a protrusion thinner than frame part, in one shot with welding electrodes meeting the seal frame shape.  
     CONSTITUTION: A package 1' for semiconductor is place on a fixed jig 6 and a cap 3 is placed on a seal frame 4'. A welding electrode 7 is lowered to 1et the comb tooth form recesses of the tapered part of the main electrode 8 of Be-Cu make contact to the outside circumferential edge of the cap 3 on the frame 4' simultaneously. At this time, auxiliary electrodes 9 are also contacted to the protruding part 11 of the frame by the spring 12. When in this stage high voltage large current is instantaneously flowed, the Ni plating of the cap and the gold plating of the frame alloy provide hermetic sealing. Since the auxiliary electrodes of the right and left are kept at the same potential, the current does not flow to the center of the cap. If the sectional area of the protrusion is beforehand made large, the generation of heat becomes small, thereby obviating the metallization breakdown of the seal frame part and enabling hermetic sealing to be performed with high reliability.

Title: Device for firing descharge lamp
Inventor: NISHIMURA KOUJI
IPC: H05B41/16
Filed: 1977-11-30
Abstract: PURPOSE: To restrict the affection of power voltage variations and temperature change or the like to a device for firing a discharge lamp by negative-feeding back to compensate the variations of set electric amount in a main circuit to phase control angle variations of a switching element using a trigger element with a control terminal.  
     CONSTITUTION: The conducting time of a trigger element 6 is controlled by the voltage at the connecting point of resistors 16 and 17, i.e., the voltage VG of a control terminal G. That is, if a transisotr 19 is not conducted, it does not conduct until VA-VAXR 17 /(R 16 +R 17 ) becomes higher than approx. 0.7V or the voltage VA reaches breakover voltage. If the transistor 19 is slightly conductied, the trigger element can be conducted when the set value of the connection of the resistors 16, 18 and the transistor 19 having resistive component in parallel is so set as to control the conduction of the element 6. Accordingly, when the output of the current detector 15 becomes large, the resistive component of the transistor 19 becomes small to delay the firing time.

Filed: 1994-06-06
Abstract: PURPOSE:To reduce the deformation of the cut section of a rectangular steel pipe at a low cost by forming a square applying a specific stress in the longitudinal direction to each side part of the square steel pipe. CONSTITUTION:A round steel pipe 1B is formed to a square through a roll group of a sizing roll 16 and reshaving rolls 17A to 17D. By adjusting the number of rotations of the roll drive motors of those stands between at least two continuous roll stands in a square forming process, a speed magnification between those stands is adjusted. Like this, a square is formed by applying a tension stress or a compression stress in the longitudinal direction, which corresponds to 2% or over of the yield stress of a square steel pipe 2, to each side part of the square steel pipe 2 to be formed to a square, passing through those roll stands. Consequently, the deformation of the cut section of the square steel pipe can be reduced without performing hot forming or a heat treatment.

In case the carburized part 18 exists, its magnetic permeability is large, and its sectional area is large and the sectional area is large, therefore, since a line of magnetic force which has been emitted from the N pole of the magnet 12 is attracted strongly to the side of the carburized part 18, a magnetic flux density of the line of magnetic force passing through the Hall element 13 increases. Accordingly, the output which has offset the electromotive voltage of the Hall elements 13, 14 becomes high in the carburized part 18, therefore, existence of the carburized 18 and its range can be decided, and also, depth of the carburized part 18 can be decided from a peak value of its output.

Title: Pattern formation
Inventor: MARUYAMA TAKASHI
IPC: H01L21/027
Filed: 1991-06-18
Abstract: PURPOSE:To increase the resolving power of a pattern by a method wherein, during a partial term of baking step, the wavelength miximizing the difference in the infrared ray transmittivity before and after the exposure of resist is selected so as to irradiate the resist with the infrared ray in this wave length. CONSTITUTION:During at least a partial term of baking step to be performed after the exposure of a resist, the resist is to be irradiated with the infrared ray in the specific wavelength having the characteristics of high absorption level in the region previously exposed but low absorption level in the region not yet exposed so as to perform the baking step. At this time, in the pattern non-formation region at lower absorption level during the exposure time, the temperature rise is low due to the low absorption level of the infrared ray while in the pattern formation region, stronger reaction is to be induced than that in the other region. Resultantly, the remarkable contrast of pattern latent image on the resist film 2 formed on a wafer 1 can be made thereby enabling sharp patterns with high resolution to be formed.
