Title: Bias magnetic field impressing device
Inventor: TERASAWA TAKESHI
IPC: G11B11/105
Filed: 1988-08-17
Abstract: PURPOSE:To uniform the distribution of the diameter directional magnetic field intensity of a disk medium by making the shapes of both edges of the cross stroke part of a T-shaped core into tapering shapes. CONSTITUTION:On the upper surface of a disk medium 3, a core 2 is provided, and the core 2 has a T-shaped side surface with a cross stroke part having a direction equivalent to the diameter direction of the disk medium 3 and is faced on the disk medium 3. The core 2 is fixed to the frame of a disk medium driver, the shapes of both the edges of the cross stroke part of the core 2 are made into the tapering shapes, and a coil 2 is wound around the vertical part and the tapering parts of the core 2. Thus, since both the edges of the core 2 goes to thin, magnetic reluctance at the parts becomes large, and it becomes difficult for magnetic flux to pass through the parts, the magnetic flux never concentrates on the parts, and the distribution of the magnetic field can be uniformed. Further, since the coil 1 is wound around the tapering parts, coil cross sections in the parts increase, coil resistance in the parts becomes smaller for that amount, and power consumption can be reduced.

Title: Polygon scanner
Inventor: KOIZUMI HIROSHI
IPC: G02B26/12
Filed: 1999-07-19
Abstract: PROBLEM TO BE SOLVED: To provide a polygon scanner capable of smoothly attaching/detaching a rotary polygon mirror without exerting excessive force at the time of attaching/detaching the rotary polygon mirror in order to easily and effectively reutilize it. SOLUTION: Surface treatment for enhancing hardness and imparting lubricity is applied to an inner peripheral part 10b of the rotary polygon mirror 10 directly attached to a rotary shaft, that is, the inner peripheral part 10b is coated with a ceramic coating film by vapor deposition or the like, for instance. Therefore, by preventing the inner peripheral part 10b of the mirror 10 from being deformed and damaged in the case of attaching/detaching the mirror 10, attaching accuracy at the time of reattaching the mirror 10 is enhanced and the excessive force need not be exerted at the time of detaching it, whereby lowering of the accuracy of a mirror surface 10a by unequal stress is prevented. Therefore, repeated reutilization of the mirror 10 is easily realized.

Title: Overheat detecting/alarming method at conductive part
Inventor: TAKADA KEIICHIRO
IPC: H02H6/00
Filed: 1991-07-19
Abstract: PURPOSE:To notify occurrence of abnormal state and the time arriving at a dangerous amount automatically by periodically detecting the temperature at a conductive part and the temperature and the pressure of ambient gas thereby calculating the time at which an abnormal state occurs and then substituting the immediately preceding time and detected amount for a time function thereby determining the saturation value of variation. CONSTITUTION:A noncontact conductive part temperature sensor 5 detects the temperature or the pressure of ambient gas in the place where a conductive part 3 connecting main circuit conductors 1, 2 is located, and thus detected temperature or pressure is then fed to the input section 8 of a conductive part overheat detector 7. The input section 8 performs A/D conversion at a predetermined period and delivers the output to a processing section 10. The processing section 10 determines a time function from the temperature/pressure which increases with time and detects the time at which the temperature/pressure reaches a dangerous state. Immediately preceding time and temperature/pressure are then substituted for the time function to calculate a saturation value of the temperature/pressure which is then substituted for the time function. According to the invention, the time at which the temperature/pressure to be detected reaches a dangerous state is detected easily and an alarm is outputted automatically from an overheat detecting/outputting section 11.

Title: Output controller for consumable electrode type arc welding power source
Inventor: MARUYAMA TOKUJI
IPC: B23K9/073
Filed: 1993-08-19
Abstract: PURPOSE:To provide an output controller for the consumable electrode type arc welding power source which does not instabilize an arc and does not uniformalize the depth of penetration to a base metal in spite of generation of disturbance, such as hand shaking and change in the shape of the base metal. CONSTITUTION:The welding current set value IR from a welding current setter 9 and the welding current detection value IF from a welding current detector 5 are inputted to an error amplifier 10. This error amplifier 10 integrates a difference between the IR and the IF, amplifies the integrated value and outputs this value as a wire feed speed command value F to a motor driver 8, thereby adjusting the wire feed speed in order to make the IR and the IF coincide. As a result, the welding current and the welding voltage are held constant even if the disturbance, such as hand shaking, is generated. A switching signal generator 11 outputs a switching output to the error amplifier 10 and the amplification degree thereof is set at the adequate amplification degree determined by a wire diameter and wire material, etc., in such a case. The arc is, therefore, stabilized and the nonuniformalization of penetration in the base metal is prevented.

Title: Hydraulic control device for air over hydraulic brake
Inventor: NAKAMURA HIROTAKA
IPC: B60T13/40
Filed: 1990-08-02
Abstract: PURPOSE:To improve the control characteristics of antilock control by switching communication of a back pressure chamber to a back pressure feedback passage or a back pressure exhaust passage by means of a pressure difference between the back pressure feedback passage of a control piston and a back pressure chamber. CONSTITUTION:When there is a possibility of a wheel lock occurring during brake, a control part closes a hold valve 21 and opens a decay valve 22. As a result, a control piston 14 is moved to the air pressure side and a cut valve 10 is closed through the force of a cut spring 15 to close a brake liquid passage 5. With the decay valve 22 opened, exhaust gas from a positive pressure chamber 20 is exerted on a valve body 34 of a switch valve 27 through an exhaust gas passage 23 and a back pressure feedback passage 26. In which case, According to relations in magnitude between an exhaust gas pressure and a sum of the pressure of a back pressure chamber 28 and the spring force of a spring 33, a valve body 34 switches a passage. This constitution prevents brake control from being brought into an unstable state due to abnormal pressurization in the back pressure chamber.
