Title: Recovery of metal component from catalyst and production of alkali metal oxalate
Inventor: TANIGAWA HIROTO
IPC: C07C68/00
Filed: 1991-12-10
Abstract: PURPOSE:To convert copper oxalate or an alkaline earth metal oxalate insolubilized and deposited in a reaction solution system into its alkali metal oxalate and to efficiently separate the alkali metal oxalate without using a special apparatus in a process for producing a carbonic acid ester without using phosgene. CONSTITUTION:Alcohol is reacted with carbon monoxide and oxygen in the presence of a catalyst composed of copper and/or an alkaline earth metal to obtain a carbonic acid ester. In this process, an alkaline metal hydroxide is reacted with copper oxalate or an alkaline earth metal oxalate respectively insolubilized and deposited in the reaction solution to convert the oxalic acid residue as the by-product into its alkali metal oxalate and to remove it out of the reactional system. The alkali metal oxalate generated in this method is soluble in a solvent such as water or alcohol. On the other hand, by-products such as copper oxide copper hydroxide, an alkali hydroxide and an alkaline earth hydroxide are sparlingly soluble in the same solvent, and therefore, solidliquid separation can readily be carried out. By this method, oxalic acid residue can be efficiently removed and the metal component in the catalyst can be recovered. This invention is also an effective method for producing an alkali metal oxalate.

Filed: 1998-10-12
Abstract: PROBLEM TO BE SOLVED: To permit a person who reads a written oracle to enable tearing off a color seal and adhering it to his or her belongings such as a bag by normally designating a lucky color in the written oracle, making the color seal being freely attachable/detachable with the designated color and adhering or fitting it to the shrine lot. SOLUTION: A lucky color 3 is normally designated in the written oracle 2. When the color is red, the red heart-shaped paper-made lucky color seal 1 being freely attachable/detachable is adhered to the right corner of the written oracle 2. Then the person who reads the written oracle 2 tears off the heart- shaped lucky color seal 1 drawing luck after reading the written oracle 2 and can adhere it to one's own bag and purse or the like. It can be adhered to any position on the surface of the lot 2 at the time of adhesion and, besides, it is adequate that the lucky color seal 1 is attached to the written oracle 2 without adhesion. Therefore, a pleasant feeling and interest are doubled.

IPC: H01G13/00
Filed: 1998-11-17
Abstract: PROBLEM TO BE SOLVED: To discriminate and remove a product with probable defect of internal structure or degradation due to aging in more perfect manner in short time, by applying a pulse voltage tens of times higher than a nominal voltage, and applying a DC voltage several times higher than a nominal voltage, for confirming an insulation resistance with a leakage current. SOLUTION: Related to a screening method for a laminating ceramic capacitor, a pulse voltage tens of times higher than a nominal voltage is applied before a DC current several times higher than the nominal voltage is applied, so that an insulation resistance is confirmed from a following leakage current, thus a product with possible defect of internal structure or degradation due to aging is discriminated and removed. Here, as the DC current several times of the nominal voltage, it may be 5-6 times of what is normally applied. As the pulse voltage tens of times of the nominal voltage, the one of 10-20 times is preferred. When that pulse voltage is applied, a product with possible degradation in internal structure or that due to aging is perfectly made into dielectric breakdown state.

IPC: B60R21/16
Filed: 1995-12-15
Abstract: PROBLEM TO BE SOLVED: To prevent atmospheric pressure in a cabin during working of an air bag from exceeding the pressure safe to a passenger's ear. SOLUTION: A solenoid valve 8 is connected to a control circuit 9, and valve-opening is controlled by applying a control current from the control circuit 9. When an automobile comes into collision with another car, and an air bag actuating signal outputted from an air bag control device is inputted into the control circuit 9, which applys the control current to the solenoid valve 8 to open it. Since high pressure air in a high pressure air tank 10 therefore passes through the solenoid valve 8, and applied to an air cylinder 7, the rod 7A of the air cylinder 7 is protruded by the pressure of the high pressure air to stamp a stamped part 4A.  Since the inside of the cabin and atmosphere are thereby mutually communicated, and the rising of pressure in the cabin caused by the expansion of the air bag is prevented, the pressure in the cabin does not exceed a value safe to the passenger's ear(hearing organ such as the tymponic membrane or the like).

Abstract: PURPOSE:To reduce the quantity of crosstalk noise by setting the depth of the read/write gap of a magnetic head device to <=20mum. CONSTITUTION:Dimensions d2 of depth 1b of a read/write gap 1a is set to <=20mum. Since the magnetic resistance of a read/write core 1 is increased to reduce the magnetic flux leaked from an erase gap 2a to the read/write core 1 according as the gap depth 1b is reduced, the erase crosstalk is reduced by the reduction of this depth. The crosstalk is considerably reduced when the depth 1b of the read/write gap is <=20mum, and S/N is considerably improved to reduce the read error without providing a center core 3 with a nonmagnetic body layer.
