Title: Regenerative injection chamber of pre-combustion chamber type diesel engine
Inventor: ISHII TSUTAE
IPC: F02B19/16
Filed: 1986-08-21
Abstract: PURPOSE:To intensify thermal decomposition and vaporization of an injected fuel by forming a nozzle hole chamber with a material of a high coefficient of thermal conductivity and a large product value of the coefficient of thermal conductivity and heat capacity. CONSTITUTION:A nozzle hole chamber 3 is formed with a material of a high coefficient of thermal conductivity, a large product value of the coefficient of thermal conductivity and heat capacity, and strong heat resistant strength, and its surface is coated with a material of strong heat and chemical resistance. This will increase the amount of heat regenerated in the nozzle hole chamber 3 from a nozzle hole chamber outer wall 5, when the pre-combustion fuel spouted out from a main nozzle hole 4 burns in a main combustion chamber because the coefficient of thermal conductivity and the product value of the coefficient of thermal conductivity and heat capacity of the material are large. Furthermore, the thermal decomposition and the vaporization of the fuel are intensified when the fuel approaches or collides against a nozzle hole chamber inner wall 6 because the amount of heat conducted from the nozzle hole chamber 3 to the fuel is copious. Therefore, the fact that the fuel atomization can be weak when the fuel spouts out from the main nozzle hole 4 allows to make the nozzle hole area large and thereby to improve the engine performance.

Title: Production of light permeable membrane like magnetic material and material prepared
Inventor: DOMINIKU JIYANIO
IPC: C01G49/00
Filed: 1989-07-28
Abstract: PURPOSE: To obtain a material having high electric resistance, saturation magnetization and light transmittance, by annealing the magnetic material of a specified thickness of an alloy contg. iron and metal of ≥1 groups of heavy rare earths at a specified temp. under flow of O 2  of a standard atm. pressure.  
     CONSTITUTION: The magnetic material MMI consisting of the alloy composed of the iron and two kinds of the heavy rare earths (for example, Tb and Gd) is deposited at <1μ thickness on, for example, a substrate SUBSI. This material is put into a furnace OF under the standard atm. pressure and is annealed at 200 to 350°C, or 300 to 330°C, under the flow F of oxygen. In such a case, the change in magnetic, optical and electrical characteristics at 200°C is extremely slow. Light is completely transmitted but the magnetism is lost and the saturation magnetization is extremely weakened at 400°C. Further, the trnasmittability is sufficient but the magnetism is hardly conceived to be sufficient for use as the base material of color magnetic ink at 350°C.

Abstract: PURPOSE: To reduce band width by separating luminance and chrominance components to a discrete frequency band. CONSTITUTION: The band width limitation of a luminance signal Y is operated by the circuit part of a controller 21. A high precise scanning standard input signal is inputted through prefilters 22, 24, and 26 and sub-samplers 30 and 32 to a channel selector 34, and one is selected according to a control signal 36 decided for an encoding path.

Chrominance components U and V are band width-reduced in the same way. U' and V' output of a band width reducer 48 are filtered by band Nyquist filters 50 and 52, added to a normal PAL encoder 54, and encoded for transmission. Thus, band width can be reduced.

Title: Directional electromagnetic steel plate completing magnetic domain control processing and manufacture thereof
Inventor: ICHIJIMA ISAMU
IPC: C22C38/06
Filed: 1984-09-21
Abstract: PURPOSE:To dissolve a problem that iron loss becomes comparatively low in case magnetic indication characteristic of a directional electromagnetic steel plate is high by providing a glass mainly composed of forstelite within holes in the form of almost trigonal pyramids at the train of points bored to the surface of directional electromagnetic steel plate obtained by an ordinary process. CONSTITUTION:The holes 3 in the form of almost trigonal pyramids are bored to the surface of a directional electromagnetic steel plate 1 and the holes 3 are provided with pinhole of forstelite at the interior thereof. Such segmentation of magnetic domain improves iron loss of a directional electromagnetic steel plate having high magnetic flux density and thereby even when the magnetic domain is comparatively large because magnetic flux density is high, a product having excellent iron loss characteristic can be obtained. Since the steel plate is in the deviation condition due to existence of solid material which does not show change of the shape up to temperature as high as 1,200 deg. or higher, the effect does not disappear even after the annealing for eliminating distortion. The most effective boring is almost the trigonal pylamid bored in the string of holes in diameter of 10mum-1mm, depth of 3-100mum and interval of 10mumnu2mm.

Filed: 1990-07-23
Abstract: PURPOSE:To obtain the rotary head assembly of a magnetic recording and reproducing device which can form a prescribed magnetic recording track by forming fin-shaped projections on the outside of yokes of a magnetic head driving part. CONSTITUTION:Fin-shaped projections 15 are formed on the outside of yokes 101, 103, and 105. The area on the outside of yokes 101, 103, and 105 is extended in such a manner to increase the contact area to the outside air. Thus, heat is positively radiated from yokes 101, 103, and 105 to the outside air. Consequently, thermal expansion of a bobbin 113 is prevented, and a magnetic head 7 attached to the bobbin 113 integrally is kept at a prescribed reference height for initial positioning.
