Publication number: 20040070342Abstract: A method of manufacturing a plasma display panel, which comprises the steps of filling a barrier rib-forming paste containing glass frit in a barrier ribs-forming intaglio and concurrently forming a paste layer having a constant thickness on the intaglio, superimposing a substrate on the barrier ribs-forming intaglio filled with the barrier rib-forming paste containing glass frit to thereby transfer the barrier rib-forming paste onto the substrate, and heating the barrier rib-forming paste that has been transferred to the substrate, thereby burning out existing organic components and concurrently sintering the glass frit to thereby form the barrier ribs and dielectric layer. The plasma display panel manufactured by this method is featured in that the barrier ribs and the dielectric layer are formed using the same barrier rib-forming material containing a low melting point glass frit.Type: ApplicationFiled: July 31, 2003Publication date: April 15, 2004Applicant: TOPPAN PRINTING CO., LTD.Inventors: Eizaburo Watanabe, Naoto Ohno, Katsumi Ohira, Junichi Arai, Isao Kato, Yasumasa Akimoto, Ikuma Nishimura, Takao Minato, Ryuichi Nakamura

Patent number: 5402681Abstract: An ultrasonic sensor for use in an ultrasonic micro spectrometer includes a concave surface transducer having a concave ultrasonic wave transmitting/receiving surface and a plane transducer having a plane transmitting/receiving surface. The concave surface transducer is capable of transmitting converging ultrasonic waves toward a specimen, wherein the waves are reflected from the surface of the specimen and are received by the plane transducer which outputs electric signals corresponding to the intensity of the reflected ultrasonic waves. Based on a signal output from the ultrasonic sensor, a digital oscilloscope and FFT analyzer forms a distribution of spectral intensity indicating the intensity of the reflected wave as a function of frequency. The digital oscilloscope and FFT analyzer further forms a distribution of spectral phase indicating the spectral phase of the reflected waves as a function of frequency.Type: GrantFiled: July 5, 1994Date of Patent: April 4, 1995Assignee: Toppan Printing Co., Ltd.Inventors: Noritaka Nakaso, Yusuke Tsukahara, Masao Saito, Katsumi Ohira

Patent number: 5060764Abstract: A method for controlling the velocity of an elevator cage by determining the optimum time delay between a velocity command signal for an elevator cage and actual movement of the cage responsive to the velocity command signal. The actual time delay is increased or decreased based on a comparison of the actual time needed for the cage to reach its maximum deceleration and the theoretical time needed for the cage to reach its maximum deceleration. The new time delay is introduced into the velocity command signal to thereby control cage velocity.Type: GrantFiled: February 20, 1990Date of Patent: October 29, 1991Assignee: Mitsubishi Denki Kabushiki KaishaInventor: Katsumi Ohira
