Title: Reel driver for magnetic recording and reproducing device
Inventor: OKUDA YASUHIRO
IPC: G11B15/18
Filed: 1990-03-02
Abstract: PURPOSE:To prevent an excess tension from being exerted to a tape by braking a reel base driven by a motor, absorbing a torque in the inside of the reel base and changing the direction of rotation of a capstan motor after loading. CONSTITUTION:One-way clutches 16, 17 are arranged on the way of delivering a torque from a capstan motor 2a to a reel and a slip mechanism is provided to reel bases 13, 14. Then a brake 18 is applied to either the supply reel base 14 or the winding reel base 13 at loading and unloading and the capstan motor 2a is driven in a direction to drive the reel base 14 or 13 subject to braking (18). Moreover, the torque is absorbed by a slip mechanism to change the drive direction of the capstan motor 2a after loading. Thus, the tape is driven in both the forward/reverse direction and excess tension exerted tot he tape at loading resulting in making a damage at loading is avoided.

Title: Hydraulic controller for automatic transmission
Inventor: NISHIO MOTOHARU
IPC: F16H61/00
Filed: 1995-03-13
Abstract: PURPOSE: To reduce hydraulic pulsation without the reduction of a responding property of command pressure along with the increase of a volume of an output pressure chamber in a solenoid valve and the degradation of an output pressure property of the solenoid valve. CONSTITUTION: A pressure-reducing valve 4 is provided with a spring retainer 12 having an opening 11, a seal material 13 sealing the opening 11 and a plug 14 clamped to shut the seal material 13 off from the whole outside. When control pressure Ps is produced on the average by opening and closing a drain port 7 to generate pressure variation due to the flow variation of oil, the pressure variation is transmitted from the chamber of the pressure-reducing valve 4 to the opening 11. Then, the seal material 13 is subject to the elastic deformation to increase the volume of the chamber in the pressure-reducing valve 4. The pressure variation is absorbed by a damping effect of the seal material so that hydraulic pulsation is reduced.

Title: Local hardening method of cast iron
Inventor: MASUDA KIKUO
IPC: B22D27/04
Filed: 1983-03-30
Abstract: PURPOSE:To harden locally a cast iron without generating chill by casting an oridinary cast iron into a casting mold, admitting air or a fluid mixture of air and water into the casting mold under cooling and increasing the cooling speed of only the required part of the casting. CONSTITUTION:An ordinary cast iron is cast into a casting mold 2 and a casting 1 having a prescribed shape is formed. Then the casting 1 undergoes the process of solidification and cooling and a fluid mixture of air and water is admitted into an air hole 4 provided through a master mold 2 and a core 3 at the point of the time when the temp. of the casting 1 attains 720-1,150 deg.C. The admission is ceased when the temp. of the casting 1 attains 300-700 deg.C. The admission of the refrigerant can be started at the point of the time when the temp. falls to the solidifying temp. of the cast iron or below and said admission is required to be started at the eutectoid transformation point or above. Air or a fluid mixture of air and water is optimum as the refrigerant and the water alone is not preferable as the water penetrates in the casting mold. The cooling speed of the casting varies with the flow rate of the refrigerant and the Brinell hardness and tensile strength thereof vary as well.

Title: Preparation of magnetic coating and production of magnetic recording medium
Inventor: KAWAI KENICHI
IPC: G11B5/842
Filed: 1997-03-07
Abstract: PROBLEM TO BE SOLVED: To provide a magnetic recording medium of excellent quality and the production process for the magnetic coating that gives the above-stated magnetic recording medium. SOLUTION: In this production process for the magnetic coating, the materials for the magnetic coating are mixed with dispersing machines as kneader, roll mill, ball mill, sand mill or the like and the resultant mixture after completion of dispersion is irradiated with ultrasonic waves to effect homogeneous dispersion. The irradiation with ultrasonic waves can be repeated several times. The more repetition, the more improvement in the degree of dispersion and mixing. There is no particular limitation in the frequency of the ultrasonic waves, but 15kHz-20kHz are preferably employed. The materials for magnetic coating are mixed and dispersed and the mixture for the magnetic coating after completion of dispersion is irradiated with ultrasonic waves to disperse the mixture homogeneously.  Then, the resultant homogeneously dispersed magnetic coating 3 is applied immediately after irradiation of the ultrasonic waves onto the nonmagnetic supporter to produce the objective magnetic recording medium. Thus, the magnetic recording medium having the high characteristics with the level the same as that of the produce produced by the high-pressure homogenizer can be produced by using a usual homogenizer. Thus, the time for washing and maintenance is saved and the operability and productivity of this process are improved than those of the conventional technology.

Title: Method for quantitatively determining of solder
Inventor: TAKAGI HIDEO
IPC: G01N21/64
Filed: 1997-03-07
Abstract: PROBLEM TO BE SOLVED: To enable a simple, speedy, and highly accurate quantitative analysis of solder. SOLUTION: This is a quantitative determining method of solder to determine the constituents of solder by irradiating a sample with fluorescent X-rays. A predetermined amount of older fragment is obtained from the solder by cutting (solder fragment sampling processor P1). This fragment is dissolved in a strong acid solution (dissolution process P2). The obtained solder solution is absorbed in a filter paper to form a sample (filtering paper formulating processes P3). The wavelength and intensity of fluorescent X-rays obtained by irradiating the sample with X-rays are measured (fluorescent X-rays analyzing process P4). The categories of metal constituting the solder are specified from the obtained wavelength, and the weight percentage of the metal constituting the solder is obtained on the basis of an analytical curve formulated in advance in the constitution of this method.

IPC: H04R31/00
Filed: 1989-03-07
Abstract: PURPOSE:To lighten weight, to raise Young's modulus, and to give a superior sound speed characteristic by using the compound consisting of SiC or SiC and TiC for a material component. CONSTITUTION:The indispensable constituent component of a speaker diaphragm is the compound material consisting of SiC or SiC and TiC. The mixing ratio of SiC and TiC lies in the range of SiC 70 to 100weight% and TiC 30 to 0weight%. When TiC exceeds 30weight%, since the specific weight of TiC is larger compared with SiC, the weight increases, and a sound characteristic deteriorates. The thickness of the speaker diaphragm needs to be 30 to 100mum in order to lighten the weight of the speaker diaphragm itself and give the superior sound characteristic, and 30 to 50mum is desirable.
