Title: Method for removing iron ion in plating bath solution
Inventor: SUZUKI TOSHISHIGE
IPC: C25D21/22
Filed: 1991-09-17
Abstract: PURPOSE:To selectively adsorb and remove only iron ion by oxidizing an iron ion in plating bath solution to trivalent by an oxidizing agent, thereafter coming a polystyrene resin base body into contact with a chelate resin having an aminocarboxylic multi-dentate ligand as a chelate ligand. CONSTITUTION:After addition of the oxidizing agent such as a hydroperoxide or ozone into the nickel (alloy) plating bath solution containing iron ion the solution is agitated to oxidizing the iron ion to trivalent. Iron ion is easily removed since bivalent iron ion, which is similar to another bivalent ion such as bivalent nickel ion in chemical property and is difficult to removed with a chelate resine, is oxidized to the trivalent. When the chelate resin having the aminocarboxylic multi-dentate ligand expressed by formula I as the chelate ligand on the polystyrene resin base body is come into contact with the plating solution, only trivalent iron ion is selectively adsobed and removed.

Title: Impact absorption type steering column device with motor-driven power steering device
Inventor: MATSUMOTO SAKAE
IPC: B62D5/04
Filed: 1996-09-06
Abstract: PROBLEM TO BE SOLVED: To prevent raising of a steering wheel and increasing the angle of a steering column along with secondary collision even when an electric motor and a housing are arranged on the upper side of the front end part of a steering column. SOLUTION: A steering shaft 1 and a steering column 22 are reduced in a overall length during secondary collision. A housing 7 fixed at the front end part of the steering column 22 is supported at a car body 26 by an energy absorbing member 11b. During secondary collision, frontward displacement of the steering shaft 1 and the steering column 22 is allowed as the energy absorbing member 11b is plastically deformed. When a distance between first and second universal joints 16 and 20 is decreased along with displacement, the overall length of a transmission shaft 17 is shortened. Approximately at this time, the overall length of the steering shaft 1 and the steering column 22 is shortened.

IPC: H01L21/301
Filed: 1991-09-18
Abstract: PURPOSE:To improve a manufacturing yield in a later step with board chips that are prevented from coming apart, by bonding a first flexible adhesive sheet to one side of the board previously, bonding then a secondary flexible adhesive sheet on the other side, and peeling the flexible adhesive sheet from one side of the substrate after the board is divided into small board chips. CONSTITUTION:An adhesive sheet 11 is bonded to one side of a wiring board 8. The adhesive strength of the sheet 11 is reduced when the sheet is irradiated with an ultra-violet ray. A flexible adhesive sheet 10 is also bonded to the other side of the board so that the wiring board 8 are fastened between two flexible adhesive sheets 10 and 11. At the same time, the adhesive sheet 10 is bonded to a ring 12. Then, the wiring board 8 is put onto a jig 13. A pushing stick 14 is pressed to a groove 9 and is moved smoothly over the face of the board so that the board is divided into small board chips. After this dividing step, the small board chips are still clamped between the flexible sheets 10 and 11, and are carried away with the ring 9 to a die bonding step. In this way, small board chips 15 are prevented from coming apart.

Filed: 1988-09-22
Abstract: PURPOSE:To improve the effective availability of metal hydride by switching the flow directions of a medium in a medium passage, and thereby uniformizing the reversible reaction of the metal hydride. CONSTITUTION:Cooling water is introduced into a working engine E to cool the engine, and the heated cooling water is introduced into a fluid circulating passage 2. When an electromagnetic selector valve 9 is set at position (a), the water flows in direction of the arrow P, branches at point 20 into branch pipelines 2a and 2b, and is introduced into containers 3. Consequently, the metal hydride packed in the container 3 is heated to discharge gaseous H2. Both water flows are joined at point 21, and the water is then allowed to flow in direction of the arrow Q and returned to the engine E as cooling water. Meanwhile, the gaseous H2 generated in the container 3 is stored in a cylinder 8 through pipelines 4 and 6, and then supplied to the engine E via a pressure reducing valve 12 and a regulator 13. When the temp. of hot water is lowered, the valve 9 is set at position (b), and hence the hot water is introduced into the container 3 from a supply line shown by the arrow Pa through point 21 and the branch pipelines 2a and 2b to generate gaseous H2, then sent in direction of the arrow Qa through point 21, and returned to the engine E via the selector valve 9.

Abstract: PURPOSE:To detect the step out, the frequency deviation, the pulse stop, the pulse trouble, or the like between master and slave clock pulses by comparing master and slave clock pulses with each other to detect the phase difference and performing a prescribed processing. CONSTITUTION:In a phase difference detecting means 1, a D-FF circuit 3 from which the master clock pulse is inputted to a terminal CP has the output terminal the inverse of Q directly connected to an input terminal D, and the clock pulse obtained by frequency division of the master clock pulse is outputted from a terminal Q. The output pulse of the terminal Q and the slave clock pulse are inputted to an exclusive OR circuit 4 and are operated, and the operation result is inputted to a shift register SFR 6. An inverter 5 of a phase difference output holding means 2 inverts the master clock pulse to input the negative-logic clock to the SFR 6, and the SFR 6 temporarily holds the output of the circuit 4. The SFR 6 sets all of outputs to code '1' if the slave clock pulse is deviated from the master clock pulse by a 1/2 period or longer, and the SFR 6 sets all of outputs to code '0' if it is deviated by an extent shorter than the 1/2 period, thus detecting the step out.

Title: Production of magnetic recording medium
Inventor: OUCHI TSUTOMU
IPC: G11B5/842
Filed: 1988-09-22
Abstract: PURPOSE:To enable short-time hardening without losing flatness of a substrate even when synthesized resin is used for the substrate by applying a magnetic coating material containing at least magnetic powder and thermo-setting resin on the substrate to form a magnetic coating film and curing the film with FIR. CONSTITUTION:The magnetic powder and binder resin, and for example, a reinforcing agent are mixed with an organic solvent to produce a magnetic coating material and then applied on a substrate by spin coating method to form a magnetic film. This film is oriented in a magnetic field with a permanent magnetic and curved with FIR. By irradiation of FIR, molecular vibration of the binder resin in the magnetic film is excited and the film itself generates heat. This accelerates hardening reaction, so that the film can be hardened at low temp. Therefore, even when a substrate made of synthesic resin is used, the magnetic film is cured in a short time while flatness required as the magnetic recording medium can be maintained.

As a result, the thermal conductibility is improved, the unevenness of the temperature of the cell itself is suppressed, and the efficiency of the cell is improved while the cell is operated smoothly.
