Title: Current control system for servomotor
Inventor: IWASHITA HEISUKE
IPC: H02P23/04
Filed: 1996-04-05
Abstract: PROBLEM TO BE SOLVED: To decrease a D-phase current generated by an interference item with D-phase voltage by a Q-phase current, so that high speediness of control can be performed, by providing a means correcting interference with the D-phase voltage by the Q-phase current. SOLUTION: DQ control performed of a current control system of a survomotor by a DC system is performed, further, in an interference correction item 17, a Q-phase current command Iq* is input, a value multiplying it by an angular speed ω and inductance L of one phase component is output as correction voltage. When a change of a Q-phase current, such as reapidly decelerating from a high speed rotational condition, is generated, by adding this correction voltage to a D-phase voltage command interference voltage, generated in a D phase side by the Q-phase current, is corrected by an interference item 15, an increase of a D-phase current, which is a reactive current, is suppressed. In this way, even at high speed rotation time, control preventing a reactive current from flowing can be performed, high speediness of motor control can be performed.

Title: Impact printer
Inventor: SAKAI HIROAKI
IPC: B41J2/295
Filed: 1989-04-26
Abstract: PURPOSE:To dispense with the hammering of printing wire with printing paper strongly through an ink ribbon and thereby perform printing at low noise level by providing a drive signal generation device which generates a drive signal to oscillate an actuator with the printing wire pressed against the ink ribbon. CONSTITUTION:If voltage is applied to a piezoelectric element 1, the element 1 becomes curved, and printing wires 2a, 2b move to printing paper 6. If a drive voltage is applied to the element 1 from a control section 8, the element 1 becomes curved and starts oscillating as the high-frequency printing voltages are overlapped. That is, the printing wire 2 oscillates with an inertial plate 3 with the paper 6 pressed through an ink ribbon 7. Consequently, a microoscillation polar pressure generates, and this pressure allows characters to be printed. After this, the drive voltage is switched OFF or a reverse voltage is applied and the element 1 ends printing of a single dot. The low microoscillation polar pressure generates a plurality of times when a single dot is printed. Therefore, the noise can be minimized, if printing is performed because of repeated low-impact pressure.

Title: Structure for connecting slide gate with submerged nozzle
Inventor: NISHIO TAKUMI
IPC: B22D11/10
Filed: 1990-04-26
Abstract: PURPOSE:To set discharging hole in a submerged nozzle to the fixed direction in a mold by fitting and connecting a submerged nozzle and a slide gate used to continuous casting with recessed part and projecting part having non circular cutting plane shape. CONSTITUTION:The recessed part 4b for connecting the submerged nozzle 4 is fitted into the projecting part 3c for connecting the slide gate 3, and the submerged nozzle 4 is fastened with the prescribed member. At this time, as the recessed part 4b in the submerged nozzle 4 and the projecting part 3c in the slide gate 3 have non-circular cutting plane, mutually only in the specific direction can be fitted. Therefore, only by fitting the submerged nozzle 4 into the slide gate 3, the discharging hole 4a of submerged nozzle 4 can be faced to the fixed direction in the mold 5. Further, even if the submerged nozzle 4 is closely fastened, the submerged nozzle 4 is not turned.

Title: Ic socket
Inventor: OKAMURA YOSHITO
IPC: H01R13/633
Filed: 1989-04-28
Abstract: PURPOSE:To provide easy fitting and removal of IC's even in case they are congested on a base board, by preventing slipping-off through retaining of the applicable IC pin when insertion is made from an IC socket case inlet, releasing the fixation when pressing is applied again in the direction of insertion, and thereby pushing out the IC. CONSTITUTION:When an IC pin 2 is depressed and insertion is made from the inlet 3 to a case 4 of an socket 100, component-A 6 moves down and a projection on the inside hitches at the end of the bottom surface of component-B 8. When external force is removed, the component-A 6 and component-B 8 are heaved by spring-A 7 to push wide component-F 15 to the left and right, and a contact 9 is pressed to an IC pin 2 for fixation of the IC concerned 1, and now component-E 13 is drawn inward by spring-C 14. When the IC 1 is depressed again, the component-A 6 widens outward because component-E 13 has shifted inward, and hitch with the component-B 8 is disengaged to release the IC 1 from fixed state. Thus easy removal can be made with IC 1 which has been mounted close to the base board thereon.

Filed: 1990-04-27
Abstract: PURPOSE:To improve the performance of identification by extracting a dictionary data for ID identification from an input picture, registering the extracted dictionary data and reading an ID code by using the registered dictionary data. CONSTITUTION:Just after a character or a code as the object of identification is written into a product 1 or a member, the picture state of the ID code 2 is stored and the pattern of the entire code is set to a dictionary pattern. Otherwise, the feature amount of the written code is evaluated according to a certain fixed rule and only the feature amount is defined as the dictionary data. Then, the dictionary of the ID code 2 is prepared and stored corresponding to the issue information of the product and afterwards, the ID code 2 is identified based on this dictionary. In such a way, the dictionary data is formed not only for the unit of each character in the ID code 2 but the data is collected from the product itself while evaluating the feature amount such as the respective areas, sizes and peripheral lengths or the like of the picture pattern in a code area and a code part. Thus, printing dispersion in the case of writing the ID code and further, the product missing the printing can be prevented in advance from flowing out by the evaluation check of printing quality.

Abstract: PURPOSE: To fix the position of generation of small swirls, by providing a projection in a flow passage to control the direction of an accessory flow when causing the flow to collide against a main swirl.  
     CONSTITUTION: A sucked mixture so introduced into the first passage 11 is divided by a projection 11b into an accessory flow (s) which goes down along the end 11c of the passage and a main swirl S which goes down while revolving around the axis of the first passage 11. The main swirl S is dispersed in a cylinder (c) slightly more than in the first passage 11 so that the main swirl changes into numerous swirls S 1 WS n  . The central one of these swirls S 1 WS n  collides against the accessory flow (s) to that local dispersion is caused. A strong turbulent flow is thus caused. Since the turbulent flow is provided with angular momentum in the same revolving direction as the main swirl S by the swirls around the turbulent flow, this flow becomes local small swirls Sm.
