Title: Printing hammer
Inventor: OTA TAKASHI
IPC: B41J2/295
Filed: 1987-08-31
Abstract: PURPOSE:To improve productivity and reduce manufacturing cost by providing the second and the third hinges on the right and left stepped parts of the first hinge, and connecting each hinge, a connecting part and a fixing member together through insertion and brazing of the both ends of each hinge into the grooves of the fixing member. CONSTITUTION:When a voltage is applied to a piezoelectric element 15 of a printing hammer, the piezoelectric element 15 extends in an arrow direction B1 to displace the first hinge 12 to an arrow direction B1. In the meantime, one end of the second and third hinges 13, 14 are fastened to a fixing member 16, while the other ends thereof are fixed to the first connection part 18 of an arm 11. The sheet hinges 12, 13, 14 are bent to an arrow direction C, causing a deformation because of a stepped part existing between the arm 11 and the hinge 12. The arm 11 also rotates to the arrow direction C. As a result, a printing wire 17 of the arm 11 receives the increased and transmitted displacement value of the piezoelectric element 15, moving to an arrow direction D for printing. Each hinge, the arm, the piezoelectric element and the fixing member are connected together by providing grooves on the fixing side and inserting the hinge into the grooves and finally brazing them. Consequently, productivity is improved and manufacturing cost is reduced.

Title: Compact image information processor
Inventor: MURANAGA YOSHINOBU
IPC: H04N1/04
Filed: 1986-09-17
Abstract: PURPOSE:To prevent a useless printing operation in advance by detecting the presence or absence of remaining printed data and informing it to an operator in case of a picture data printing. CONSTITUTION:In printing a picture data, a print signal S2 by the print mode from a control section 51 is sent to a remaining print data detection section 64. Thus, the transistor (TR) of an LED section 50 is operated and a remaining print data LED is subjected to a light control. When a read designation address to a picture data memory 60 is coincident with the write final address and is detected that there are no remaining data to be printed, the remaining print data LED of the LED section 50 is subjected to an extinguishment control. Thus, the presence or absence of printed data in the picture data memory 60 is informed instantly by applying printing while confirming the lighting state of said remaining print data LED.

A power source 8 is connected to the heat generating film 4, feeding a current to the conductive films 6, 7 in series. There is provided another power source 9. A voltage generated at both ends of the superconductive body is amplified by an inverting amplifier 12, and a differential voltage is measured by a voltmeter, so that the position of the liquid surface is detected as the voltage change. Accordingly, since the normal conductive element and superconductive element are arranged side by side and connected in series, when the conductive elements are made conductive, the measuring error of the liquid surface level is negated, and the correct surface level can be measured.

Inventor: KIDA MASASHI
IPC: F02B3/06
Filed: 1993-09-02
Abstract: PURPOSE:To obtain a catalyst with which particulate material in exhaust gas from a diesel engine can be efficiently removed by depositing a catalyst compo nent containing iron, Mn, and refractory inorg. oxide and a catalyst component containing noble metal selected among platinum and Rh and refractory inorg. oxide in one layer on a refractory three-dimensional structural body. CONSTITUTION:This catalyst is obtd. by depositing catalyst components (A) and (B) in one layer on a refractory three-dimensional structural body (e.g. ceramic foam). These components are the first component (A) containing iron, Mn and refractory inorg. oxide (e.g. silica). and the second component (B) containing at least one noble metal selected from Pd, platinum and Rh, and refractory inorg oxide. This catalyst has excellent performance in a low temp. region to remove harmful components such as carbon fine particles, unburnt hydrocarbons, and CO. Further, in a high temp. region, the oxidizability of SO2 is low so that production of sulfate can be suppressed. Thereby, the catalyst is excellent in the reduction of particulate material in exhaust gas from a diesel engine.

IPC: G01N21/90
Filed: 1998-08-03
Abstract: PROBLEM TO BE SOLVED: To detect minute defects such as chips and cracks at the mouth part of a container with accuracy. SOLUTION: The circular image of the mouth part of a container is once stored in image memory 3, and then its part is horizontally or vertically scanned by a scanning means 4 and is binarized by a binarizing means 5. A change point detecting means 6 detects the coordinates of the rising point and falling point of every scanning line, and a width detecting means 7 obtains the difference between both of them as a width. The obtained width is compared with a reference value predetermined by the location of the circular image. Thereby, it becomes possible to detect even a defect in which changes in the local inclination of a visual outline are small.
