Title: Controller for stepping motor
Inventor: TAKAHASHI YASUTAKA
IPC: H02P8/22
Filed: 1987-03-16
Abstract: PURPOSE:To smoothly decelerate a device without generating oscillation and noise, by micro-step-driving a magnetic field to be lagging phase to a rotor angle in a short period, in case of stopping. CONSTITUTION:At the time of deceleration, according to a counter value from an interval counter 7, a deceleration displacement from a deceleration displacement table 9 is gradually increased. In the meantime, a deceleration phase difference from a deceleration phase difference table 12 is set to be constant on lagging phase at 90 degrees. The deceleration displacement and deceleration phase difference are added to each other and are added to windings 25, 27 via an electrical angle register 18. As a result, according to the displacement of a rotor angle, phase in a magnetic field is changed in a minute period. Accordingly, the sudden and extreme change of torque applied to a rotor 28 is not generated.

Filed: 1990-03-15
Abstract: PURPOSE:To reduce code quantity by using a signal stored in a frame memory giving a most similar signal among signals in plural frame memories so as to apply coding based on a difference signal of a frame memory to be coded. CONSTITUTION:Plural memories 2-1 to 2-3 storing plural scenes are provided to both a transmission side and a reception side, and a same referenced picture is inputted in advance respectively. Then the transmission side picture discrimination section 14 judges to which scene stored in the frame memories 2-1 to 2-3 an inputted moving picture signal M1 is similar, uses a frame memory giving the similar scene for coding and informs a frame memory section signal S representing which frame memory is selected to the reception side via a frame memory section signal line 15. Thus, when plural scenes are sent alternately, the increase in the coding information quantity when the scene is changed is suppressed.

IPC: H01L23/02
Filed: 1991-03-27
Abstract: PURPOSE:To disperse the concentration of stress and strain caused by thermal expansion of a ceramic substrate into each of the solder connection parts, by dividing a sealing body into the ceiling panel side and the side panel side. CONSTITUTION:A sealing body is divided into a ceiling panel 9 and side panels 10. When an LSI 4 is operated, the generated heat is conducted to a ceramic substrate 1, in which thermal expansion is generated. The stress and strain generated in this case are applied to solder 6, the side panels 10, and the ceiling panel 9. Since a solder connection part is divided into two parts, i.e., substrate 1-side panel 10 and side panel 10-ceiling panel 9, the strain and stress generated in each solder connection part can be dispersed into each solder connection part. By using the solder 6 connecting substrate 1-side panel 10 and side panel 10-ceiling panel 9, a constant connection height is formed, so that the internal stress and strain in each solder 6 can be reduced.

Abstract: PURPOSE:To maintain a uniform flow rate distribution and to cast a thin metallic sheet having good quality without rippled surfaces, etc. by providing a box- shaped gate formed with notches for outflow of a molten metal on one side face between a nozzle and rolls. CONSTITUTION:The space between a pair of the casting rolls 4 is set at a prescribed distance and thereafter the rolls are rotated at a required speed and the molten metal is poured into said space from the nozzle 1. The molten metal 3 received in the gate 2 overflows from notches 7 on both side faces in the form of the broad thin film-like flow along the axial direction of the rolls and flows down toward the surface of the rolls 4. The molten metal 3 in contact with the rolls 4 is immediately cooled and solidified to form shells. The shells move between the rolls and below the same; at the same time, a molten metal pool is formed by the molten metal supplied successively between the shells. The solidified shells are drawn out below the rolls according to the rotating speed of the rolls and a thin billet 6 is thus obtd.

IPC: H02P25/10
Filed: 1988-03-18
Abstract: PURPOSE:To detect a trouble without malfunction by detecting as a trouble only when the output voltage values of at least one or two phases of three phases exhibits abnormality. CONSTITUTION:The voltages of the phases of a 3-phase AC exciter 1 are output by a transformer 6, fed through an arrester 10, a smoothing circuit 11 and an A/D converter 12, and input to a discriminator 7. In order not to operate a detector at the time of normal operation such as start or stop, a trouble signal is not oscillated when the signals transmitted from the phases are all '0' or '1' (i.e., stopping and normal operating states). However, only when at least one of these signals is '0', the detector judges that a trouble occurs in the exciter 1 to generate a trouble signal.
