Title: Optical beam scanning device
Inventor: SUMI KATSUTO
IPC: G02B26/10
Filed: 1988-01-07
Abstract: PURPOSE:To adjust the magnification of an image, etc., that is read or recorded by varying the wavelength of an optical beam to use the chromatic aberration and adjusting the scanning range of the optical beam. CONSTITUTION:The temperature (t) of a laser diode 23 constituting a laser emitting part 12 is detected by a temperature sensor, and compared with a prescribed temperature t0 by a comparator 25. The temperature t0 is a temperature to obtain the wavelength lambda of a laser beam L1 for synchronization necessary to scan on grid 36 in a desired scanning range. Then, corresponding to an output from the comparator 25, the temperature (t) of the diode 23 is adjusted to the prescribed temperature t0 by using a temperature adjuster 26 in order to obtain the laser beam L1 for synchronizing having the necessary wavelength lambda. Therefore, the laser beam L1 is adjusted of its scanning range by means of the chromatic aberration of a scanning lens 28, hence scans on the grid 36 in a desired scanning range. As a result, a synchronizing signal having a desired synchronization can be generated from a pulsative optical signal obtained from the laser beam L1 passing through a slit 34. Thus the magnification of an image on a film F can be adjusted.

IPC: G03G15/09
Filed: 1994-01-13
Abstract: PURPOSE:To attain color image printing high in quality by preventing the electrostatic charging amount of a two-component developer from lacking due to the frequent execution of toner replenishing operation by data printing or the like high photographic density. CONSTITUTION:In the case of developing printing data in each toner color, the execution history of toner replenishing operation is stored, a lacking state in the charging amount of the developer is predicted by the frequency of the toner replenishing operation, and the agitation of developers in respective developing units 30Y, 30M, 30C, 30K is added so as not to generate the lack of the charging amount. Even in a compact color electrophotographic device obtained by reducing the size and weight of a developing device, the charging amount of the developer can be prevented from lacking due to toner replenishment at the time of frequently printing out printing data with high photographic density, and while suppressing the reduction of printing speed to its minimum, color image printing with high quality can be attained.

Filed: 1989-01-10
Abstract: PURPOSE: To apply a film without enclosing air by backing a curing film made of a polymer material with a surface to be protected of processed goods and a hard flat member and including it between elastic pads with a free contact surface in specific shape and pressing it. CONSTITUTION: An elastomer pad 50 is in pyramid shape in free state without any mechanical pressure. The pad is backed by an Al plate 52. A top 54 is located at the center of a contact surface 56. When the pad 50 is moved to the surface of a corresponding printed wiring board 58, the top 54 is brought into contact with the surface, the contact surface with the printed wiring board 58 increases at a constant rate, finally the contact surface 56 becomes parallel with the surface of the printed wiring board 58, and air is pushed out of an interface. The similar effect can be obtained by initially bringing a thick edge 66 into contact with a printed wiring board 64 using an wedge pad 60. With this configuration, the curing film of a polymer material can be applied to, for example, a printed wiring board and a wafer without sealing air.

Filed: 1987-01-08
Abstract: PURPOSE:To prevent the retreat of a vehicle and allow a smooth start on a sloping road by judging a start on a steep sloping road based on a gradient detecting means and a state judging means and determining and increasing the control quantity of the engine torque quantity with a control quantity determining means in response to the road surface gradient. CONSTITUTION:The stop state of a vehicle is detected by a stop state detecting means (a), if it is in a stop state, its retreat is blocked by a retreat blocking means (b). If a state judging means (d) judges that a vehicle is transferred from a stop state to as travel state, the control quantity increasing the torque quantity is determined by a control quantity determining means (e) in response to the road surface gradient detected by a gradient detecting means (c).

Abstract: PURPOSE: To control brake torque by applying the wheel slip rate as well as its acceleration and deceleration to control factors so that the wheel slip rate can be within the proper range at braking.  
     CONSTITUTION: When the value of the wheel speed voltage signal Uwi is smaller  than that of the reference wheel speed voltage signal Ur and when the value of the wheel acceleration voltage signal U'wi is smaller than that of the reference wheel deceleration voltage signal -V'wo, the danger of wheel locking is assumed to have occurred.
