IPC: C07C255/54
Filed: 1979-10-19
Abstract: PURPOSE: To obtain a substituted phenol useful as a raw material for an agricultural chemical, etc., in high selectivity and yield, by three stages of reacting a substituted isopropylphenol with an organic halide, oxidizing the resultant product, and decomposing the oxidation product with an acid.  
     CONSTITUTION: A substituted isopropylphenol expressed by formula I (R is H, halogen or lower alkyl) is reacted with an organic halide expressed by formula Ar-X [Ar is formula II or III (X 1  is H, CF 3 , halogen, etc.; X 2  is H, halogen, cyano, etc.), etc.; X is halogen], in the presence of a base, e.g. KOH, preferably in a solvent, to prepare a substituted isopropylbenzene expressed by formula IV (the first stage). The isopropylbenzene thus obtained is then oxidized with O 2 , in the presence of an alkali catalyst and if necessary a radical initiator (the second stage), and the resultant substituted isopropyl peroxide expressed by formula V is decomposed, with an acid to give the aimed compound expressed by formula VI.  
     EFFECT: Even a small amount of an inorganic salt is enough for the reaction.

Title: Switching regulator
Inventor: KITAJIMA TOKIMUNE
IPC: H02M3/28
Filed: 1982-08-02
Abstract: PURPOSE:To reduce the switching loss and the noise of the titled device by a method wherein the currents of switching transistors are made to a sine wave form utilizing resonance action of a coil and a capacitor. CONSTITUTION:When the switching transistor 3 is made to ON, an input voltage is applied to a winding 12, and a voltage is induced in a winding 13. As a result, a resonance curent flows into the capacitor 15 according to resonance action of the coil 14 and the capacitor 15. When the transistor 3 is made to OFF, and the transistor 18 is made to ON next, electric charge of the capacitor 15 is discharged to the capacitor 8 according to resonance action with the coil 17. Because the currents to flow in the respective transistors 3, 18 become to the sine wave type, noise to be generated is limited to a fundamental wave. Moreover the currents of the transistors 3, 18 are zero at turn-ON time and turn-OFF time, no switching loss is generated, and no surge current is generated also.

Filed: 1990-05-28
Abstract: PURPOSE:To make the temperature of a heat-generating resistance body on each of lines of recording paper and the temperature of each of the heat-generating resistance bodies on each of the lines rise to the same level under the same conditions by a method wherein ferroelectric substance coat having positive temperature coefficient is added in specified quantity to a place near the heat-generating resistance body to which the addition is made in each of the heat-generating resistance bodies or in each of electrodes that supply electric current to the heat-generating resistance bodies. CONSTITUTION:As electric current is supplied from electrodes 4a, 4b to a heat-generating resistance body 3 at the time when recording is on a certain line of recording paper, the temperature in a temperature-sensitive variable resistance body 7 rises, together with the rise of the temperature in the heat-generating resistance body 3, heat conducted from the heat-generating resistance body 3. Therefore, with adjustments for positions where the resistance body 7 is added and for quantity and thickness of the addition made based on known data, heat value by electric current in the heat-generating resistance body 3 wherein the heat is accumulated decreases by the heat value equivalent to the heat accumulate. Ferroelectric substance coat in 50-300 deg.C Curie point is used as a material for the temperature- snesitive variable resistance body 7 that suddenly increases its resistivity at certain temperature. Such resistance bodies are formed respectively to specified positions with a manufacturing device.

Title: Heat ray absorbing glass
Inventor: NAKAGUCHI KUNIO
IPC: C03C3/087
Filed: 1989-05-29
Abstract: PURPOSE:To produce the heat ray absorbing glass high in visible ray transmittance, low in solar radiation heat transmittance and appropriate for the building and vehicle by incorporating specified amts. of iron oxide and tin oxide into the heat ray absorbing glass to obtain a specified dominant wavelength. CONSTITUTION:The heat ray absorbing glass contains >=0.1wt.% iron oxide expressed in terms of Fe2O3 and >=0.2wt.% tin oxide expressed in terms of SnO2 and has the dominant wavelength of >=565nm measured by an A light source. FeO in the iron oxide is the heat ray absorbing component. When the content of the iron oxide expressed in terms of Fe2O3 is controlled to <0.1wt.%, the heat ray absorbing effect is reduced, and the visible ray transmittance is unfavorably lowered at >=1wt.%. The tin oxide effectively increases the amt. of FeO among the iron oxides in the glass. When the amts. of the iron oxide and tin oxide in the glass is increased, the amt. of FeO is increased. When the content of tin oxide is controlled at <0.2wt.%, FeO is not increased, and FeO is not increased at >5wt.% tin oxide.

IPC: H01F1/18
Filed: 1996-05-30
Abstract: PROBLEM TO BE SOLVED: To enhance the magnetism shielding efficiency of a magnetic shielding material, to give the beautifulness of a visual appearance and a superior corrosion resistance to the shielding material and to prevent components on the periphery of the shielding material from being contaminated by a method wherein an anti-corrosive film containing an organic resin as its main component is dried on the surface of a forsterite film and thereafter, the anti-corrosive film is formed in a weight in a specified extent and the content of S of a directional electromagnetic steel plate is set at a constant rate or lower including the anti-corrosive film. SOLUTION: The content of S of a directional electromagnetic steel plate is set at 0.005wt.% or lower including an anti-corrosive film. The weight of the anti-corrosive film containing an organic resin as its main component is set in an extent of 2 to 10g/m<2> in the weight subsequent to a drying of the film. When the content of the S of the steel plate formed with a film exceeds 0.005wt.% and the steel plate is used as a magnetism shielding material, a color charge, corrosion or the like of a motor commutator is caused in the case where a member to be shielded, such as a small-sized motor, is magnetically shielded. When the guide amount of the anti-corrosive film is less than 2g/m<2> , the full corrosion resistance of the film is not obtained. Moreover, when the guide amount of the anti-corrosive film exceeds 10g/m<2> , the bending work resistance of the film is deteriorated.

Filed: 1983-07-25
Abstract: PURPOSE:To correct the dispersion of storage batteries, improve the stability and reliability of the performance, and allow a quick charge or a discharge at a heavy duty cycle by using a connector with a current collector having an angle- like cross section arranged in a Y-shape or T-shape. CONSTITUTION:A connector 1 is constituted with a lead section 2 connected to a battery terminal and a current collector 3. The current collector 3 is formed in an angle by press machining. The bend angle forming the angle is made 45 deg.- 90 deg. for the stability of the angle, and widths of two slant faces of the angle are made nearly equal. The current collector 3 of the connector 1 with such a shape is brought into contact with the exposed portion of the core of an electrode plate, the bottom surface of the welded electrode is scraped in a triangle analogous to the rear face of the current collector, it is pressed to the upper face of the current collector 3 and welded by applying the vertical pressure to the electrode. At this time, the slant faces of the current collector receive an outwardly opening stress respectively, but they are blocked at points in contact with the upper end of the exposed portion of the core of the electrode plate, and the biting force is increased. Therefore, the current from a welding electrode is easily concentrated there, and welding can be reliably performed.
