IPC: B41J2/44
Filed: 2000-01-31
Abstract: PROBLEM TO BE SOLVED: To effectively and surely prevent the banding by vibration of a return mirror and casing with simple constitution. SOLUTION: This optical scanner 21 has a light source 26, a rotary polygon mirror 28 on which the light emitted by this light source 26 is made incident, a drive means 25 which rotates this rotary polygonal mirror 28, the mirror 31 which introduces the scanning light, i.e., the light scanned by the rotary polygonal mirror 28 to a prescribed direction, the casing 23 which housed the mirror 31 and the rotary polygonal mirror 28 an opening possessed by the casing 23, and a cover member 24 which closes its opening. The mirror 31 is brought into contact with the cover member 24.  Accordingly, even if the vibration emitted from the drive means 25 for rotating the rotary polygonal mirror 28 is transmitted to the respective parts of the optical scanner 21, the vibration of the mirror 31 is suppressed by contact of the mirror with the cover member 24 and therefore adverse effect on the formed image, such as banding, may be lessened.

Title: Electric car controlling device
Inventor: MATSUOKA NARIYASU
IPC: B60L7/22
Filed: 2000-02-17
Abstract: PROBLEM TO BE SOLVED: To increase electric brake force in high speed range in an electric car controlling device for driving an induction motor in which regenerative and dynamic braking systems are utilized together. SOLUTION: When an electric brake is applied in the high speed range, a second unit switch 4 is opened to conduct a first resistor 5 connected parallel to the second unit switch 4 and to actuate a regenerative brake via a pantograph 1. Because a voltage that is determined by the regenerative current flowing in the first resistor 5 and the resistance of the resistor 5 increases the input DC voltage of an inverter circuit 10, the three-phase AC voltage of the induction motor 11 increases. Because of the characteristics of the induction motor, magnetic flux increases proportionally as the voltage does, and the torque of a main motor increases. As a result, electric brake force can be obtained in the high-speed range without increasing braking current.

Title: Optical pickup and optical disk device
Inventor: HINENO SATORU
IPC: G11B7/1381
Filed: 2000-02-14
Abstract: PROBLEM TO BE SOLVED: To prevent characteristics of a focal error signal from deterioration owing to a horizontal deviation with a simple constitution by differentiating the length of the optical pathes of two luminous fluxes into which return light is decomposed and condensing one luminous flux on a light receiving surface with a large beam spot in front of or behind a focus even when the focus is formed on the light receiving surface by the other luminous flux. SOLUTION: Laser beam L1 exited from a semiconductor laser 32 is decomposed into -1st order, zero order and 1st order diffracted light beams by a grating 33, transmits a beam splitter 34 and is condensed on an information surface of an optical disk 5. Return light L2 is reflected by the beam splitter 34, is separated into two luminous fluxes whose exiting directions are different by a Foucault prism 37, and is received by a light receiving element 38. At this time, one of two luminous fluxes transmits an optical path different plate 39, and the length of an optical path up to the light receiving element 38 is set so to differ from the other luminous flux. Thus, condensing of the whole light quantity of the return light L2 into a dead zone of the light receiving element 38 is avoidable.

IPC: B41J19/20
Filed: 2000-02-17
Abstract: PROBLEM TO BE SOLVED: To provide a scanning member supporting mechanism for accurately supporting a scanning member, and an image forming device having a scanning member supporting mechanism. SOLUTION: A plate 100 for placing a scanning head is supported by a shaft 16 via sleeves 102, 104 provided below as well as supported by a shaft 18 via a sleeve 106. The sleeve 16 has a hole part 106 of the same diameter as that of the shaft 18 so as to face-contact with the shaft 18. Therefore, abrasion by scanning can be restrained so that the inclination of the plate 100 can be maintained in a predetermined state. Furthermore, even in the case the shafts 16, 18 are assembled not parallel with each other, since the plate 100 is interlocked with the sleeve 106 relatively movably, the sleeve 106 can move along the shaft 18. Thereby, the scanning rate of the plate 100 can be maintained constantly so that the image irregularity can be restrained.

Title: Image forming system
Inventor: MATSUI NORIAKI
IPC: B41J5/30
Filed: 2000-02-28
Abstract: PROBLEM TO BE SOLVED: To reduce occurrence of 'full memory' state. SOLUTION: Regarding the storage of compressed image data in a memory for compressed image data memory 304, when the 'full memory' state has not occurred and another document needs to be read, the system fetches the memory of near-full size, corresponding to the document size from the RAM 308 table and decides whether the compression data memory 304 still can afford that amount of memory space, that is, whether the 'near-full memory' state occurs. When the 'near-full memory' state occurs, the document will be read after the space in the compression data memory becomes available. On the other hand, when the 'full memory' state has occurred, the volume of the image data that caused this 'full memory' state is regarded as a new 'near-full memory' size and RAM 308 is updated thusly.  When the compressed image data memory 304 has available storage space thereafters, the image data in the reader memory 302 is compressed and stored in the compressed image data memory 304.
