Patent JP-S6040525-A (JP)
Title: Information signal reproducer
Inventor: YOSHIHIRO MITSUGI
IPC: H04N5/783
Filed: 1983-08-15
Abstract: PURPOSE:To perform the satisfactory tracking by providing a correcting voltage generating circuit which produces the prescribed correcting voltage to a driving circuit for driving bimorph element. CONSTITUTION:A correcting voltage generating circuit K produces the correcting voltage which is similar to the hysteresis characteristics of the drive voltage- displacement amount of a bimorph element 4. The correcting voltage V2 given from the circuit K is supplied to an operational amplifier 3 which constitutes a driving circuit 7 for element 4 and added to the drive voltage given from an LPF2. Thus it is possible to give a displacement to a torary magnetic head 5 in the direction approximately orthogonal to the scan direction of a rotary magnetic head 5 and approximately in proportion to the drive voltage applied to the element 4. This ensures the satisfactory tracking with an information signal reproducer.

Title: Servo control system as well as apparatus and method relatedto it
Inventor: TOOMASU ROBAATO ARUBUREHITO
IPC: G11B5/584
Filed: 1995-06-15
Abstract: PURPOSE: To reduce position signal error and moreover facilitate the detection of the position signal error by executing determination of position with a periodical synchronous feature in the servo pattern detected by servo decoder. CONSTITUTION: A magnetic flux transitional servo pattern is detected by a servo read head 26 and this head 26 generates an analog servo read head signal to be supplied to a signal decoder 36 via a signal line 34. The decoder 36 processes the servo read head signal to generate a positional signal supplied to a servo controller 40 via the signal line 38. The controller 40 generates a servo mechanism control signal then supplies this signal to a head assembly 24 via the control line 24. The servo mechanism of the assembly 24 moves, responsive to the control signal from the controller 40, the head 26 in the moving direction exceeding the width of the servo track 30. The controller 40 monitors the positional signal from the decoder 36 to generate the control signal reaching the desired position. Such signal is equal to the signal appearing when the head has reached the desired position.

Title: Image processing system
Inventor: NOMURA KEIICHI
IPC: G06F3/153
Filed: 1988-06-16
Abstract: PURPOSE:To shorten a processing time by attaching a FIFO, a sub CPU, and an image processor on each of a memory to store a display image and a memory to store an original image, respectively. CONSTITUTION:A main CPU5 writes a processing request content from an operator on FIFOs 9b and 10b, respectively. Subprocessors 9c and 10c read out the contents of the FIFOs 9b and 10b sequentially, and output processing instructions to the image processor. By employing such system, it is not required to monitor the processing states (whether or not a processing is completed) of a display part and an original image part, and it is enough of write the next processing content on the FIFO unilaterally. Waiting is requested only when on vacancy exists in the FIFO. Since not only a display processing and an original image processing can be performed in parallel but the original image processing can be performed at the hidden side of an operating time, it is possible to shorten the processing time to reply to a request from the operator.

Filed: 1988-06-16
Abstract: PURPOSE:To prevent operability from being lowered by a load on a host computer by informing an inputted character code to an application program as it is, and informing a control code to the program after converting to a character code. CONSTITUTION:When an ordinary character string is inputted, a character input request from the application program 32a is accepted by an input control part 33, and a terminal equipment 10 inputs the character string, and waits the transmission of the character code. When the character code is transmitted, it is informed to the program 32a as it is. When the program 32a requests the input of a hidden character string, the transmission of the control code from the equipment 10 is waited similarly. The input of the hidden character string is performed by depressing a function key 12 and depressing a keyboard 11. Thereby, the equipment 10 generates the control code, and transmits the control code to the host computer 30. When the control code is transmitted, the input control part 33 converts the control code to the character code by referring to a conversion table 34a, and informs the character code to the program 32a.

Electrode plates are placed in the electrolytic degreasing liquid in this case and the non-plating surface 3 of the steel sheet 1 is placed to face the positive electrode. The non-plating surface of the plate 1 is maintained at a negative polarity and is electrolytically degreased. Or if the polarity of the steel sheet changes according to the movement of the sheet 1, the surface 3 is electrolytically degreased so as to have the negative polarity in the final. Zn or Zn-Ni alloy is thereafter plated on the surface 4 by which the steel plate which has the non-plating surface having excellent phosphatability and paintability and is galvanized on one surface is thus obtd.

Title: Control of knocking of internal-combustion engine
Inventor: SUEMATSU TOSHIO
IPC: F02P5/153
Filed: 1982-08-31
Abstract: PURPOSE:To prevent erroneous operation by using the first comparison standard value and the fixed second comparison standard value which are based upon background value, as standard value, in the method for detecting knocking by comparing knocking value with the standard value. CONSTITUTION:It is judged in step 701 whether knocking signal value a>K.b or not with respect to the comparison standard value K.b which is varied according to background signal value (b). In case of YES, generation of normal knocking is judged, and step 702 is executed. In step 702, ignition timing is delayed. In step 703, it is judged whether the knocking signal value a >1.5V with respect to a certain comparison standard value corresponding to a knock sensor output of 1.5V. In case where a <=1.5V, it is judged that knocking is not generated, and step 706 is executed. On the contrary, if a >1.5V, generation of knocking is judged, even if a <K.b. Thus, the erroneous operation due to the fact that the background value rises can be prevented.

Title: Cleaning method for embedding hole of after executing anchor
Inventor: KIMURA MICHIO
IPC: B23B47/34
Filed: 1987-06-18
Abstract: PURPOSE:To obtain a simple cleaning method for stabilizing the fixation of an adhesion type anchor and for increasing tensile strength by inserting while rotating a wire brush with spirally arranged wires into a hole to send chips out of the hole while simultaneously forming unevenness on the side face of the hole. CONSTITUTION:As a wire brush with spirally arranged wires having nearly the same diameter as a hole diameter is inserted into a hole while being mechanically rotated, a sand matter 4 and a cement matter 5 on the side face 2 of the hole are scraped off by the wire brush. At the same time, the sand matter 4 and cement matter 5 are sent out of the embedding hole along the spiral rotation of the wire brush to form fine unevenness on the side face 2 of the hole. Then, when the execution of anchoring is carried out, the fixation of an anchor by an adhesive can be stabilized because of hitching due to the unevenness on the hole side face 2 while increasing tensile strength. Further, any of a suction or a blow-out operation is not necessary in cleaning, enabling cleaning simply in a short time.
