Title: Method and apparatus for blow injection molding
Inventor: HISAMITSU HIROTOMO
IPC: B29K101/12
Filed: 1997-03-31
Abstract: PROBLEM TO BE SOLVED: To recycle gas without necessitating a recovery surge tank or the like by recovering injected gas through a communication between a vacuum part in which a cylinder chamber is made vacuum in its cylinder mechanism and a hollow part in which a pressurized gas is injected in the inner part of resin within the mold. SOLUTION: By keeping a charge valve 16 and gas bent valve 30 in a closed state, a gas injection valve 26 is changed over from its open state to its closed state and, simultaneously, a gas recovery valve 35 is changed over from its closed state to its open state. At this time, a front cylinder chamber 12 remains in a vacuum state. On the other hand, since the hollow part with filled gas of the mold 4 is in a highly pressurized state, gas in the hollow part moves into the front cylinder chamber 12 passing through a gas recovery passage 32 by the agency of pressure difference between the hollow inner part pressure and the front cylinder chamber 12 pressure, thereby completing gas recovery. After this, the gas vent valve 30 is opened so as to discharge a very small quantity of gas remaining in the passage outward.

Title: Tape recorder
Inventor: NINOMIYA YOSHIHIKO
IPC: G11B5/027
Filed: 1997-03-31
Abstract: PROBLEM TO BE SOLVED: To reduce motor noise and upgrading the sensitivity of a microphone when the tape recorder has a built-in microphone at the time of recording. SOLUTION: A gain difference between sound received by the built-in microphone 6 and sound received by a built-in speaker 7 is corrected by a gain difference correcting amplifier circuit 1 at the time of sound recording operation. Subsequently, only the motor noise is extracted from a signal outputted by the gain difference correcting amplifier circuit 1 by a band pass filter 2. Then, a phase of the motor noise extracted by the band pass filter 2 is reversed by a phase correcting circuit 3. Moreover, a signal outputted from the built-in microphone 6 and a signal outputted by the phase correcting circuit 3 are mixed up by a mixer 4. Since the motor noise is in the opposite phase, these signals are canceled by each other, and no output is sent from the mixer 4 to a recording amplifier 5 in the next stage at all.

Abstract: PROBLEM TO BE SOLVED: To hold a magnetic material inside without using an adhesive by disposing the magnetic material on a sheet base material, laminating a sheet thereon, making it pass a nip part having two rolls with a specific linear pressure, and calendering it to integrate them. SOLUTION: A magnetic material 2 is disposed on a sheet 1 by a magnetic material spreader 6, another sheet 3 is further superposed, passed through a nip part 4 having two rolls by a linear pressure of 500 to 2500 kg/cm, and integrated without using adhesive. Thus, adhesive component is exudated in the steps of printing, punching and cutting, entangling of sheet fibers is further strengthened by applying a high pressure without contaminating an apparatus due to exudating the component. In the case of cutting or punching, fluffing of a cut surface or drop of fiber is reduced to obtain satisfactory cutting characteristics. And, in the case of recycling after use, separation of pulp from magnetic metal can be facilitated.

Title: Record reproducing method
Inventor: MORITA HIROSHI
IPC: G11B5/39
Filed: 1994-04-19
Abstract: PURPOSE:To obtain reproduced output excellent in symmetry by making the magnetic field asymmetric which is caused by input signals arising from the magnetic recording medium when the biasing magnetic field B to be applied to an MR(magnetoresistance effect) element is weak. CONSTITUTION:When the biasing current, i.e., biasing magnetic field is weak due to the variance of film thickness in MR elements and biasing conductor, magnetization of the N-pole and S-pole opposite to the magnetic recording medium is made asymmetric so that this asymmetric magnetic field of input signals and the inappropriate biasing magnetic field combine to compensate asymmetry and give rough symmetry to the output signals. Different values of magnetomotive force are obtained between the N-and S-poles when the number of turns of the magnetic coil of the recording magnetic head is different from each other between these poles.

A constant current of a constant current source 104 is inverted by a constant current circuit consisting of TRs 106, and 108 and supplied to TRs 78, 80, 92 and 94 respectively. The active voltage impressed to the head 2A is increased up to 4.5V although the power supply voltage VCC is lowered down to 5V. This attains the drive at a low level of voltage. Thus it is possible to drive a writing circuit for floppy disk with a portable power supply such as dry cells, etc. Then a portable floppy disk device is obtained.

Title: Stepping motor control method
Inventor: SUGIMOTO YUKIHIKO
IPC: H02P8/14
Filed: 1989-03-30
Abstract: PURPOSE:To reduce the temperature rise of a motor by providing the exciting phase of each step with an OFF section at the time of a low speed rotation, when a stepping motor is rotated by successively switching the driving pulse of a stator coil with plural phases. CONSTITUTION:When a driving pulse 10a is inputted to an excitation control circuit 8a, respective a pair of poles out of poles 11-14 of the stator of a stepping motor 9 are successively excited by exciting waveforms Q11-Q14. When e.g. the poles 11 and 12 become S poles, a rotor R steps to the midway between said poles 11 and 12 and stops as shown in the drawing. Then, when poles 12 and 13 are excited, said rotor R steps 90 deg. and stops at the position indicated by the dotted line. At the time of a low speed rotation, power application to poles to be excited is limited to the beginning and terminal parts of an exciting waveform and no power is applied during the intermediate periods. Thus, it is possible to inhibit the temperature rise of a coil and to reduce the amount of power consumption.

The swelling portions 12 are formed at positions facing four corner portions in the diagonal directions of a panel portion 2 fluorescent screen 6. Thereby, even when the deflection yokes 9 are mounted as shifting to a neck portion 4 side further than usual, clearance between a funnel portion 3 inner face and electron beams can be easily increased without interfering with the deflection yokes 9. Accordingly, the magnetic field energy of the deflection yokes 9 can be lessened so that consumed power can be reduced.

Abstract: PURPOSE:To obtain a dense, high-quality and large-area crystal thin film at the time of forming the thin film on a substrate with a precursor obtained by the reaction of a gaseous raw material with au oxidizing agent as a supply source by changing the magnitude of bias energy to be impressed. CONSTITUTION:A gaseous raw material and a gaseous oxidizing agent are separately introduced into a reaction vessel 103 respectively from inlet pipes 101 and 102, and both materials are allowed to react with each other. Consequently, plural precursors including an excited precursor are formed. The precursors are used as the supply source of the thin film constituting elements. Bias energy such as light energy 110 is then supplied to the substrate 104, and the magnitude of the energy 110 is changed. The flow rate ratio of the oxidizing agent to raw material is reduced in the phase where the substrate temp. is high in synchronization with the magnitude of the energy 110 to be impressed on the substrate 104, and the ratio is increased in the phase where the substrate temp. is low.
