Title: Purificaition of enzyme
Inventor: OKAMOTO UTAKO
IPC: C12N9/64
Filed: 1982-04-21
Abstract: PURPOSE:In the purification of spleen fibrinolytic enzyme and an elastase-like enzyme in granular leukocytes, the use of a water-insoluble polysaccharide containing a specific synthetic substrate immobilized thereon gives high-purity enzyme in high yield. CONSTITUTION:Succinyl-L-tyrosyl-D-leucyl-D-valine-p-nitroanilide is bonded to a water-insoluble polysaccharide such as cellulose or crosslinked dextrin to prepare a ligand-immobilizing agent. The product is suspended in a buffer solution containing sodium perchlorate and packed in a column. Then, the same kind of buffer solution containing spleen fibrinolytic enzyme or an elastase-like enzyme in granular leukocytes is made to flow down through the column to effect adsorption of the enzyme. The ligand-immobilizing agent is rinsed with the same kind of buffer solution to remove impurities and the enzyme is eluted using a buffer solution containing urea, then the urea is removed and the product is stored.

Title: Black lead for pencil and automatic pencil
Inventor: YOSHIDA MITSURU
IPC: C09D13/00
Filed: 1979-05-26
Abstract: PURPOSE: To provide improved black lead having smooth writing touch and giving dense black trace, by using an esterified product obtained from a polyhydric alcohol having a neopentane skeleton and an aliphatic carboxylic acid, etc., as an imprignating oil.  
     CONSTITUTION: The objective black lead is prepared by impregnating a sintered mixture of graphite and clay with an impregnating oil comprising an esterified product synthesized from (A) a polyhydric alcohol having a neopentane skeleton (e.g. trimethylol propane) and (B) an aliphatic carboxylic acid, an aromatic carboxylic acid or a naphthenic acid (each having pref. 5W20 carbon atoms). The esterified product is pref. a partially esterified product having OH groups, and having a kinetic viscosity of ≤25cst at 100°C.  
     EFFECT: Since the oil has a high heat stability, the impregnation temperature can be raised to reduce the impregnation time. Little thermal deterioration of the oil allows the semipermanent use of the oil.

Filed: 1980-05-19
Abstract: PURPOSE:To determine the existing quantity of an antigen easily with good accuracy by sensitizing a mixture of immunoglobulin F(ab')2 fragments and Fc fragments with latex particles, and allowing the resultant sensitizing latex particles and the antigens in humors to react. CONSTITUTION:A mixture of immunoglobulin F(ab')2 fragments and Fc fragments obtained by enzyme decomposition of immunoglobulin with Pepsin is sensitized with latex particles of 0.1-1mum average grain sizes. Thence, the resultant sensitizing latex particles and humor sample are mixed, and the existing quantity of the antigens is determined by such a method of deciding the degrees of latex flocculation caused by the reaction of the antigens in the sample and the immunoglobulin F(ab')2 sections by naked eyes or irradiating light of 0.3-1.8mum wavelengths  and measuring the absorbancy thereof or the intensity of the scattered light. Thereby, the measurement is made without receiving the interference of RA factors or  the like in spite of their existance in the sample.

Title: Recording and reproducing device for rotary magnetic recording medium
Inventor: MAEDA YUTAKA
IPC: G11B5/09
Filed: 1988-03-22
Abstract: PURPOSE:To use the A/D converting circuit of low accuracy for an envelope detector circuit by making the gain of the envelope detector circuit detecting the envelope of the reading signal of a magnetic head changeable in high and low two steps at least. CONSTITUTION:In a track/serch processing a detected envelope is compared with a specified threshold/level only, so no trouble is caused by raising the gain of an envelope detector circuit 83 even if the detected envelope is saturated. On the contrary whether the detected envelope exceeds the threshold/level or not becomes easier to decide. In the peak position detecting processing of the envelope even the small difference in the envelope/levels is clarified by increasing the gain of the detector circuit 83 by a switching circuit 100 to facilitate the detection of the peak position. In case of the detection envelope being saturated the gain is decreased, hence the envelope/level is made easy to be stored within the range capable of A/D conversion.

Title: Preparation of manganese-aluminum-carbon alloy magnet
Inventor: IBATA AKIHIKO
IPC: B21K23/00
Filed: 1982-04-19
Abstract: PURPOSE:To obtain a magnet having high magnetic characteristics in the diametric direction with small compressive stress by a method wherein a hollow steel piece of magnet made of alloy of polycrystalline Mn-Al-C system that has been made anisotropic is compressed in the axial direction at the preselected temperature in such a manner as to make free at least part of its internal and external peripheries. CONSTITUTION:A known alloy of Mn-Al-C system for preparing a magnet is extrusion-processed at 530-830 deg.C to obtain a uniaxial or facial anisotropic magnet. A hollow steel body 1 of the magnet is compression-processed at the temperature range of 530-830 deg.C in such a state that at least part of the internal and external peripheries thereof is set free. In the case of the uniaxial anisotropic magnet, compressive stress must be 0.05 or more at the logarithmic value. With this construction, the magnets of both the anisotropic types display high magnetic characteristics in the diametric direction and the part locally compression- processed has higher magnetic characteristics in the diametric direction, so that flaws such as uneven transformation or a permanent band can be avoided.

Filed: 1989-03-20
Abstract: PURPOSE:To reduce a circuit scale by revising a bit number to be collated from (n) bits into (n+1) bits after the pulse train of consecutive (n) bits is coincident with any of partial patterns. CONSTITUTION:A pattern collation means 7 collates a pulse train in consecutive (n) bits detected at first base on a reception pulse 6 as to whether or not any of m-set of n-bit partial patterns generated from an m-bit synchronous pattern 8 is coincident with the pulse train. When any coincidence is detected, a synchronization protection means 9 establishes a 1st stage backward protection to allow the pattern collation means 7 to revise a received pulse string into a consecutive (n+1)-bit train, detects all the n-set of consecutive (n+1) bits of reception pulse strings detected continuously with the shift of one multi-frame each coincident with any of the partial patterns and establishes one state of backward protection after the 2nd and subsequent stages of the multi-frame synchronization. Thus, the circuit scale is reduced.

IPC: H01F27/34
Filed: 1984-04-05
Abstract: PURPOSE:To enhance reliability against impulses due to a thunderbolt by providing two insulating angle barriers extended along an end surface of a winding from an end of a static shielding body formed by winding an electrode and insulator of a thin sheet layer alternately one by one turn on the outer side of a basic insulating cylinder disposed contiguous to the winding. CONSTITUTION:An high voltage end shield 34 is provided along the upper end of a winding 10. This end shield 34 is connected with a line terminal and covered with an insulator 35 of large coating thickness. Two L-shaped insulating angle barriers 36 and 37 are provided along the outer surface of the high voltage end shield 34 over the upper end of the winding 10 from both sides of an end 30a of a static shielding body 30. The winding arranged in this way allows its series static cappacitance to be equivalently increased by the static shielding body 30. Since the static shielding body 30 is made integral with a basic insulating cylinder 31, it is made small in size and light in weight, and easy to manufacture. Since an end of an electrode 32 at the end 30a of the static shielding body 30 is, so to speak, sandwiched by both metal shields 38 of the insulating angle barriers 36 and 37, an electric field is by no means concentrated at this end 30a.
