Title: Method for separating and purifying aromatic component
Inventor: IWANAMI YATSUHIRO
IPC: C07C7/163
Filed: 1986-04-22
Abstract: PURPOSE:To obtain high-purity BTX readily by superfractionation with most inexpensive energy, by obtaining 6-8C fraction obtained by removing cyclopentadiene from a specific hydrocarbon oil, hydrogenating the fraction at two stages and separating an aromatic component. CONSTITUTION:A hydrocarbon oil (e.g. cracked gasoline prepared as a by- product in production of gaseous olefin by thermal cracking of naphtha, etc.) containing 6-8C aromatic components is distilled to give <=5C fraction and >=6C fraction. Then, 6-8C fraction and a cyclopentadiene-containing fraction are distilled and cyclopentadiene is distilled and separated from the fraction. Then, the 6-8C fraction from which cyclopetadiene is removed is obtained as a bottom product, subjected to hydrogenating and purifying treatment at two stages and the aromatic component is separated. EFFECT:Cyclopentadiene can be recovered in high purity.

Abstract: PURPOSE:To enable to cope with the flow rate of gas by changing the number of the self same component parts to be employed by a method wherein a housing body is constituted by combining elementary pieces with basic profile and the resistance at the inlet and outlet of gas can be made variable by changing the combination of the elementary pieces. CONSTITUTION:The elementary piece 1 has a center hole 2 and a corner hole 3 eccentric to the center hole 2 and is provided with a counter-bore 4 at the  upper surface and with packing grooves 5 at the upper and lower surfaces. One  elementary piece 1 is placed upside-down on another adjacent elementary piece 1 so as to form a gas inlet port 11 in the upper part of the housing or a primary chamber 14. The lower part of the housing is piled up in a different way of piling-up from that employed in the upper part in order to form a secondary chamber. A regulating valve 8 is arranged so as to divide the interior of the housing into the primary chamber 14 and the secondary chamber 15. The opening and closing of the valve 8 is performed by means of the difference of the  pressures in both the chambers 14 and 15. The passage leading from the inlet  port 11 to the primary chamber 14 can be made suitable for the flow rate of gas by adjusting the number of the elementary pieces 1 to be piled-up.

IPC: A23L13/60
Filed: 1993-03-30
Abstract: PURPOSE:To obtain the subject food maintaining meat granular and found feel in good workability without altering raw meat flavor and without impairing its gel strength by using specific two kinds of proteins as those in a protein- chitosan binder. CONSTITUTION:This meat product can be obtained by using, as the proteins in a protein-chitosan binder, 0.5-4wt.% of soybean protein and 0.1-5wt.% of whey protein per 100wt.% of the binder. Concretely, for example, as a reconstituted raw meat product for e.g. 'shabu-shabu' (thinly sliced meat boiled shortly), the soybean protein and whey protein at the above proportion are dissolved in water followed by adding chitosan and a dietary acid to the resultant solution to produce a binder, which is then neutralized and mixed with meat, and the resultant mixture is packed in e.g. a resin film and frozen.

Title: Color image forming device
Inventor: UCHIYAMA AKIHIKO
IPC: G03G15/01
Filed: 1994-04-08
Abstract: PURPOSE:To obtain an image whose density is always stable even when generating sudden fluctuation in environment by selecting and using a mode of performing normal image forming and the mode of allowing a transfer material carrier to, carry transfer material before image forming and performing transfer bias control. CONSTITUTION:A CPU 23 calculates the variable of absolute temperature stored in a RAM 24, and compares the absolute value of the variable with a specified variable stored in the ROM 25. It is judged that the sudden fluctuation does not occur in the case that the absolute value of the variable is smaller than the specified variable to perform the normal image forming. On the other hand, in the case that the variable of absolute humidity is equal to or above the specified variable, it is judged that the sudden fluctuation in the environment occurs. In this case, when the transfer material is wound on a transfer drum 5, the image forming in a first color is not performed, and specified constant current bias is impressed from a bias power source 21 by a command from the CPU 23, and voltage at this time is set as the transfer voltage of the first color, and the transfer voltage of the second and succeeding colors is calculated based on this value, and the normal image forming is performed by using the transfer voltage.

Title: Test method of memory device
Inventor: MURAYAMA MASAMI
IPC: G11C29/02
Filed: 1982-06-01
Abstract: PURPOSE:To detect quickly a fault for both address and data system. CONSTITUTION:For instance, it is supposed that the lowest bit of a counter CT1 is stacked to ''1''. Thus an address 1, i.e., address 0001 is read out of a memory MEM1 when an address 0 of a MEM2 is read out. Then the check result of a parity check circuit CH shows an error to detect a fault. Such a stack is equal not only with the lowest bit of the counter CT1 but with any bit position. When a data on the 2nd address (address 1) of the MEM2 is read in case the lowest bit of the CT1 is stacked to ''0'', the data on the 1st address (address 0) is read out of the MEM1. Then a fault is detected by the circuit CH.

Abstract: PURPOSE: To obtain highly tough ceramics, having a high fracture toughness value and excellent in mechanical functional properties, etc., by dispersing and including coarse dendritic Si3 N4 crystal grains in a matrix comprising fine Si3 N4 crystal grains. CONSTITUTION: A growth nucleus is applied to the surface of β-Si3 N4 powder 5 constituting coarse dendritic crystal grains 2 and a material 6 (e.g. Y2 O3 ) capable of providing a crystal grain growth promoter is then fixed to the surface of the β-Si3 N4 powder 5 by calcining. The resultant material is subsequently mixed with α-Si3 N4 powder 3 containing a crystal grain growth retardant 4 (e.g. CaO). The prepared mixed powder is then sintered to afford highly tough ceramics having the constitution of the coarser dendritic Si3 N4 crystal grains 2 than the Si3 N4 crystal grains 7 dispersed in the matrix 1 comprising the fine Si3 N4 crystal grains 7. The resultant highly tough ceramics can be loaded with a high stress and is useful in the field requiring high reliability, e.g. a material for producing engine parts.
