Patent JP-H04101869-A (JP)
Title: Printer
Inventor: KARASAWA MITSUNORI
IPC: B41J9/48
Filed: 1990-08-22
Abstract: PURPOSE:To maintain a uniform printing density of a character by a simple structure and by easy control of a motor by a method wherein when the character is printed, rotary speed of a motor corresponding to said character is retrieved, and printing is performed by rotating the motor continuously during one cycle for printing one character at the retrieved rotary speed. CONSTITUTION:A MPU 34 reads one by one a character to be printed from a buffer to select a type 16. When the character is recognized, the MPU 34 judges said character to be which number of a kind of character according to a program, retrieves a memory 42, and reads rotary speed of a DC motor 40 corresponding to the kind of the character. Thereby, the MPU 34 completes driving preparation of the DC motor 40, i.e., printing preparation. At that time a hammer 10 exists at a stand-by position, and the MPU 34 rotates the DC motor 40 during one cycle of printing at the read out rotary speed.

Title: Glide head for magnetic disk
Inventor: DOBASHI MASATO
IPC: G11B5/127
Filed: 1990-08-23
Abstract: PURPOSE:To easily and surely detect the projection existing on the surface by fixing directly an end pat of a detecting member formed by a piezoelectric material whose piezoelectric constant is high so that it projects from an end part of a glide head. CONSTITUTION:A detecting member 4 is formed by PZT whose piezoelectric constant g31 is high, and fixed directly through an adhesive agent so as to project from a free end edge 2a of a glide head 2. In this case, since the detecting member 4 is supported like a cantilever, vibration can be more amplified. Also, since the detecting member 4 is fixed directly onto the upper face of the glide head 2, vibration in the vertical direction of the glide head 2 can be detected directly. In such a way, a projection existing on the surface of a magnetic disk can be detected surely.

Abstract: PURPOSE:To measure of the moving extent of cloth by non-contact, and also, to measure a vibration of a motor, and to obviate an error caused by stretching of cloth, by comparing images obtained by photographing the surface of cloth by an ITV camera. CONSTITUTION:An ITV camera 3 for the upper cloth is installed so as to be opposed to a sewing machine table 2 being in the vicinity of a needle bar of a sewing machine 1, and two images before a movement and after a movement of the cloth from this camera are detected. Output signals of these two images are A/D-converted 4 and stored 5. Also, the signals of these two images are inputted to an arithmetic unit 6, a mutual correlation value of the signals of two images is calculated, and its result is inputted to a CPU 8 and compared with a calcibrated value which has been derived in advance. As a result, the calculated value is corrected, and from the respective corrected values, a moving extent of cloth is calculated exactly, and by an upper feed control motor, an error of a relative feed quantity of the upper cloth and the lower cloth is corrected. Also, since a distance of every stitch is measured successively by non-contact, the slide of the cloth and a measuring instrument, and the vibration from the sewing machine, etc., are reduced, and the moving extent of the cloth can be derived exactly.

Filed: 1997-08-19
Abstract: PROBLEM TO BE SOLVED: To improve the insulation withstand voltage between a positive electrode plate and a negative electrode plate while maintaining high luminance, a high resolution and a high vacuum degree inside a panel by providing a positive electrode plate between a negative electrode plate ad a spacer support member, and passing plural columnar spacers of the support member through plural holes of the positive electrode plate without generating a contact so that the spacers make contact with the negative electrode, and supporting the atmospheric pressure to be applied to the negative electrode plate. SOLUTION: A positive electrode plate 2 contacts with a spacer support plate 3 at the only one part, but it dose not make contact with a spacer 7. A creeping distance from a conductive film of the positive electrode plate 2 to a surface of the negative electrode plate 1 is obtained by adding up a seal member 17, a surface of the spacer support plate 3 and a surface of the spacer 7, and in the case where a space between the negative electrode plate 1 and the positive electrode plate 2 is set at about 200 μm, the described creeping distance can be set at 5 mm or more with respect to the creeping distance at about 0.3 mm, when the spacer 7 is made to make contacts with the positive electrode 2. With this structure, it becomes different for discharging to be generated in a surface of the spacer 7, and the insulation withstand voltage can be improved from approx 400 V to 2 kV.
