Title: Process for depolymerizing polysaccharids having a rod-like helical cenformation
Inventor: KOGIMA DAKEMASHA
IPC: C07H1/00
Filed: 1983-02-02
Granted: 1990-08-25
Abstract: Degradation of polysaccharides of cylindrical helix structure into low mol. wt. cpds. comprises keeping a soln. of the polysaccharides under a condition of high speed shear. Highly viscous polysaccharides useful as food or drugs, partic. immune potentiating antitumour agents (e.g. beta-1,3-glucan), are converted into easily handling less viscous LMC without decreasing their pharmacological activity or changing the toxicity profile. When polysaccharide is used as food additive, it is possible to opt. decrease fluidity which makes filtration ease.

Title: Level indicator
Inventor: BEGAS HENK W A
IPC: G01R19/00
Filed: 1985-09-21
Granted: 1993-07-31
Abstract: For displaying the ratio in decibels between the instantaneous value and the maximum value of a digital signal a rectified digital signal is serially applied to an input (4) of a level indicator. This indicator comprises a shift register (10) which, in the case of an indicator with a resolution of 2 dB, comprises three series-connected flip-flops (11, 12, 13). The input (M) of the first flip-flop (11) is connected to the input (4) of the level indicator. The flip-flops (11, 12, 13) each comprise an output (QA, QB, QC), which like the input (M) of the first flip-flop (11) are connected to the inputs of a combination circuit (20). The output (QC) of the last flip-flop (13) is also connected to the input of a read-enable circuit (15). For each bit of the digital signal which is loaded into the shift register (10) the combination circuit (20) generates a number from the signals on the outputs (QA, QB, QC) and the input (M) of the shift register (10), which number indicates how many times an amount of 2 dB should be subtracted from the said ratio. In an adder (30) this amount is added to the previous amount and the sum is applied to a memory (40) whose contents is transferred to a read-out device (50) at the instant at which the read-enable circuit (15) supplies an output signal.

Title: Fourier transform ion cyclothon resonance mass spectrometer with spatially separated sources and detector
Inventor: MEEK JOHN T
IPC: G01N27/62
Filed: 1985-12-23
Granted: 1994-03-25
Abstract: A Fourier transform ion cyclotron resonance (ICR) mass spectrometer, with a vacuum housing comprising three differentially pumped regions allows spatial separation of the processes for generation, translocation, and detection of the ionic species. The ion source provides inlets for solid, liquid, and gaseous samples,from direct injection or chromo- tagraphic interfaces. Provision is made for ionization by electron impact, chemical ionization, fast atom bombardment, and laser ionization. A sys<sub>'</sub>em of electrostatic lenses accelerates, focusses, and decelerates the ions for transmission to the ion detector. The mass analyzer includes an ion cyclotron resonance cell in which the ionic motions are detected by amplification of a small "image" current induced in the walls of the cell and made to flow through external detection circuitry. The characteristic frequencies of the ionic motions are revealed by Fourier transformation of the digitized image current, and related to the ionic masses by a simple algebraic calibration function. High resolution and accuracy in the measured masses are achieved through the ultra high vacuum in the analyzer region, and the use of very large data tables for the digital representation of the image current. Such large data arrays (typically 512K words) require the use of a high speed array processor for the Fourier transformation and other mathematical processing, and high capacity magnetic storage media for the mass spectral data arrays. Electronic circuitry achieves an extremely large dynamic range in the ICR mass measurement.

Title: Track jump method at data reproducing apparatus
Inventor: DIETOR BAAS
IPC: G11B7/08

Granted: 1996-12-04
Abstract: 2.1 In the case of an apparatus for the reproduction of data, which can be read by means of an optical scanning device from the data tracks of a recording medium by it being possible to guide a light beam on the data tracks by means of a track control circuit, during track jumping the optical scanning device is moved to the desired data track by a jump pulse (SI) and stopped there by a brake pulse. Because the brake pulse is always the same, major deviations from the desired track are possible, requiring subsequent correction. 
<??>2.2 In order to adapt the brake pulse to the respective jumping conditions, when jumping from one track to the next an over-small first brake pulse (B1) is emitted and the time (T) taken to reach a predeterminable point (P) of the next data track is measured. The measured time (T) is taken to determine the amplitude and/or duration of a second brake pulse (B2), which stops the optical scanning device approximately in the middle (M2) of the data track. In the case of a second solution, a test jump is carried out with a subsequent test brake pulse. The transient response of the track error signal is taken to determine the amplitude and/or duration of the brake pulse required for subsequent jumps and is stored.

Abstract: In a manufacturing method for support springs of a video tape cassette, a plate material is passed through a pair of  upper  and lower dies by a pair of upper and  lower  rollers  operated  by  a servo motor intermittently. The upper and lower dies form a series of dies to form support springs progressively. In the  first  step the plate material is punched and cutted at the same time. In  the second step the position of the plate material is set by insertion of pilot pin. The last step is a  bending  process  to  allow  the support spring  a  proper  angle  of  inclination.  This   method minimizes waste of material and shearing  stress  in  the  cutting process.

     그리고, 마주보는 평면벽부는 안쪽으로 돌출한 1개 또는 복수개의 굴곡돌기가 있어, 그 굴곡돌기의 끝부분과 평면벽부의 내면 또는 대응하는 굴곡돌기의 끝부분과 맞닿은 상태에서 접합되어 단일체로 된다. 
     그러므로 극박형이면서도 내압성이 뛰어나고, 또 제조상의 문제점도 없어 생산성이 뛰어나고, 저럼한 비용으로 제작하여 공급할 수 있다.

Title: Method for making binding hole of an insulator
Inventor: SHIN CHANG-HO
IPC: H02G3/30
Filed: 1991-12-14
Granted: 1996-10-14
Abstract: The method is designed to form a bind hole for fixing an incoming wire with a "bind" line. The method includes the steps of forming a direct penetrating hole at the center part of a protrusion formed at ta porcelain insulator and opening and installing more than one guide hole around the protrusion area.
