Title: Magnetic head
Inventor: KITAGAWA HIDEO
IPC: G11B5/127
Filed: 1980-08-11
Abstract: PURPOSE:To obtain a magnetic head that suppresses the demagnetizing effect during the recording and to realize the high density recording, by providing a small iron piece near the gap of a ring-type head. CONSTITUTION:A magnetic head consists of a ring-shaped magnetic material core 1 having a gap 2, a magnetic rectangular parallelepiped bar 3 made of the same material as the core 1 and a magnetism supply coil 4. A magnetic tape 5 is transported so that the gap 2 is set right-angled to the transport direction. Owing to the bar 3 set near the gap 2, the attenuation is made sharp for the distribution of magnetic field intensity in the direction parallel to the gap 2. Thus the recording demagnetization can be suppressed, and the feature of the lateral recording can be derived most effectively.

Title: Telephone set
Inventor: NIWA FUMITO
IPC: H04M1/02
Filed: 1998-04-21
Abstract: PROBLEM TO BE SOLVED: To keep excellent speech quality of the portable telephone set provided with a close-talking type ECM independently of its operating mode and to enhance the operating convenience. SOLUTION: When a flip 3 is turned open with respect to a main body 2, both sound holes of a close-talking type ECM 11 are open and a sound wave acts on a diaphragm in both directions, and in the case of making a speech while approaching the close-talking type ECM 11 to the mouse of the user, a proximity effect is obtained and the excellent speech quality is ensured. On the other hand, when the flip 3 is turned closed with respect to the main body 2, one sound hole of the close-talking type ECM 11 is closed by a packing 24, only the other sound hole is open and the sound wave acts on the diaphragm in one direction only. That is, the close-talking type ECM 11 acts like an omnidirectional ECM virtually and even in the case that a speech is made while the close-talking type ECM 11 is apart from the mouse, the excellent speech quality is ensured.

Title: Hydraulic driving device
Inventor: UEHARA KAZUO
IPC: F16H47/02
Filed: 1982-06-29
Abstract: PURPOSE:To reduce a space, by connecting a fixed displacement motor and a variable displacement motor in parallel to a variable displacement pump and joining together the output side of the fixed displacement motor and the output side of the variable displacement motor to produce an externally fetchable output. CONSTITUTION:A fixed displacement motor 3 and a variable displacement motor 4 are connected in parallel to a variable displacement pump 2, and the output side of the fixed displacement motor 3 and the output side of a variable displacement motor 4 are joined together to produce an externally fetchable output. This permits a device to have a function equivalent to that of the variable displacement motor having a capacity which is the summation of the capacity of the two motors of the fixed displacement and variable displacement motors 3 and 4. As a result, the use of said two motors 3 and 4 enables the required space to be less than that of one motor having a high capacity.

Abstract: PURPOSE:To reduce waveform distortion caused due to fluctuation of base- emitter voltage of a transistor(TR) by connecting a base of a common base stage of a 1st differential amplifier circuit in cascade connection to the collector of a differential amplifier stage of a 2nd differential amplifier circuit. CONSTITUTION:A couple of TRs Q1, Q2 form a differential amplifier using its base as the input terminal and the 1st differential amplifier circuit consists of TRs Q1-Q4, resistors R1, R2, RE and load resistors RL1, RL2. Moreover, the collector of TRs Q5, Q6 is connected to the base of common base TRs Q3, Q4 and connected to a constant voltage power supply VCO via load resistors RL3, RL4.

Title: Bead gimbal assembly and hard disk drive device provided with it
Inventor: SHIRAISHI KAZUMASA
IPC: G11B5/48
Filed: 1996-04-09
Abstract: PROBLEM TO BE SOLVED: To reduce parasitic capacity and to improve dynamic oscillation characteristics in a head gimbal assembly by partially removing the metallic suspension below the lead pattern for magnetic head. SOLUTION: Plural through-holes 38 are formed in a stainless steel plate of the flexure 30 by, e.g. etching. Namely in the section of the flexure 30 which is located below the lead patterns 34a-34b, plural through-holes 38 penetrating the stainless steel plate are bored to reduce the area of the flexture which constitutes the electrode opposing the lead pattern. By this, the parasitic capacity formed between the lead pattern and the flexure is reduced. In actual, the electrode-to-electrode distance of the capacitor is enlarged by using a load beam 32 for the electrode opposing the lead pattern in the part of the holes 38. And because the mass of the suspension itself can be reduced, the mechanical resonance characteristics are improved.

Filed: 1985-05-24
Abstract: PURPOSE:To detect the passage of an original precisely by detecting the passage of the original to the 1st and 2nd discharging parts by a pair of an original detecting means consisting of a detecting lever and a reed switch. CONSTITUTION:In the original detecting means, the original A discharged like U-turn through the 1st original discharge passage 38 is abutted upon the detecting lever 47 and tries to push up the lever 47 and a magnet 46 fitted to the lever 47 is separated from the reed switch 48, so that the reed switch 48 outputs an OFF signal.
