Title: Automatic focusing of reading sensor for automatic drawing machine
Inventor: TAKAHASHI YASUSHI
IPC: B43L13/00
Filed: 1989-02-21
Abstract: PURPOSE:To set the focus automatically without an automatic focusing device by providing a mark reading sensor interlocked with a writing utensils holder, allowing the holder to move upward and downward with the help of an actuator, and positioning the holder based on a position signal connected from the sensor when a light intensity integrated over time reaches a maximum level. CONSTITUTION:A drawing head 6 is connected to a mark reading sensor 42 and the mark is read on roll paper. A processor allows a writing instrument holder 22 to move downward to a lower dead point using a lifting member 16. After this, the holder is moved upward to an upper dead point. In this case, a light current output from the mark reading sensor 42 is stored in accordance with a digital value indicated on a position sensor 34. The output light current reaches a maximum level when sensitivity is at a maximum point during the movement of the sensor 42 to a top position. The processor stores the position of the holder 22 in memory based on the position sensor 34 when the light intensity reaches a maximum level. The position of the holder 22 corresponding to the maximum level is stored in memory. This procedure is repeated a specified number of times to calculate the average value of the position of the holder 22 corresponding to the maximum value of each light intensity.

Abstract: PURPOSE: To produce a solid electrolyte having a sufficient strength for a thermal shock by making stabilized zirconia (in cubic phase) and instabilized zirconia (in monoclinic phase) coexist and take preset diameter distribution.  
     CONSTITUTION: Stabilizing material such as yttrium or calsium is mixed with zirconia, and the resultant mixture is sintered and pulverized. Sinter promoting additive (such as kaolin) is mixed with the resultant particles, and the mixture is molded into a preset shape. This molding is then sintered to produce such a solid electrolyte for an oxygen concentration sensor as has both cubic and monoclinic phases and as contain smaller particles having a surface particle diameter of 0.2 to 4 μ and larger particles having a surface particle adimeter of theee times of the former. Incidentally, most of the smaller particles are contained in the nonoclinic phase whereas most of the larger particles are contained in the cubic phase. In order to effect such particle diameter distribution, the blending ratio and of the zirconia and yttrium during production and the sintering temperatures have to be adjusted.

Title: Manufacture of acrylic resin sheet with protective film
Inventor: OGURA KOJI
IPC: B29L9/00
Filed: 1998-02-24
Abstract: PROBLEM TO BE SOLVED: To eliminate the development of dents or scratches due to bubbles at the manufacturing time of a sheet by a method wherein a protective film is placed on at least one side of an acrylic resin sheet and stuck together by being passed between a pair of pressure rolls, the temperature of which on the same side as the protective film is set at a specified value. SOLUTION: By supplying and sticking two sheets of protective films 2 and 2, which are wound about two rolls 22 and 22 so as to be pasted onto both side of an acrylic resin sheet 1 with the predetermined thickness through feed rollers 3 and 3 between a pair of pressure rolls 4 and 4 to the acrylic sheet 1 in order to be stuck the films and the sheet to each other. If the temperatures of the pressure rolls are below 50 deg.C, no effect for suppressing the biting of bubbles between the acrylic resin sheet 1 and the protective film 2 is obtained. As a result, the temperature of the pressure roll is limited to be 50 deg.C or higher.  The resultant assembly stuck together integrally is passed between a pair of second pressure rolls 5 and 5 so as to be fixed by pressure, resulting in allowing to remove bubbles even when they are entrapped between the acrylic resin sheet 1 and the protective films 2 stuck to each other in the previous process and to manufacture the resin sheet without developing dents and scratches due to bubbles.

Abstract: PURPOSE:To reduce the collector loss of a controlling transistor (TR), to improve the efficiency and to facilitate the radiation design, by applying a voltage corresponding to an input voltage as a control input divisionally from a reference power supply element and a resistance. CONSTITUTION:The voltage between input terminals 1 and 1a is denoted as Vin, and the voltage between output terminals 2 and 2a is denoted as Vout, and voltages at points M and N are denoted as Vm and Vn respectively. In respect to the voltage Vin, a normal commercial power is transformed by a power transformer and is converted to a DC by a rectifying circuit and is supplied through a smoothing capacitor. Consequently, this voltage is lowered by a DC resistance or the like of the transformer when the current is increased. TRsQ11 and Q10 are subjected to the Darlington connection for the purpose of increasing the output current of the controlling TRQ10. The control input is supplied to the TRQ10 from the branch point of the voltage due to resistances R10 and R11.
