Title: Image forming device
Inventor: MATSUTOMO YASUSHI
IPC: G03G21/18
Filed: 1996-05-29
Abstract: PROBLEM TO BE SOLVED: To provide an image forming device capable of surely detecting the mounting condition, without requiring so much positioning accuracy of a member for the mount detection disposed on a replacement cartridge side by detecting a mounting state by replacement of the replacing cartridge in a non-contact state. SOLUTION: The device is provided with a magnet 23 on a tooth lacked gear 30 rotated by a prescribed angle by a transmission gear 29 by which respective constituting inside member of the replacement cartridge 22 is rotated. When the new cartridge is mounted, output of a magnetic sensor 21 becomes large under the influence of the magnetic force by the initial position (a) of the magnet 23, hence an initial state can be detected. Moreover, in connection with the image forming operation, the tooth lack gear 30 is rotated by a given angle, the magnet 23 is moved to the position (b), the magnetic force produced by the magnetic sensor 21 becomes smaller than the initial time, and its output also becomes smaller, however it is larger than the output when the replacement cartridge 22 is not mounted. Therefore, if the replacement cartridge 22 is mounted again, the mounting can be detected, and it is prevented from detecting the cartridge as the new one.

Title: Production of ceramic whisker
Inventor: NAKADA TOSHIO
IPC: C30B25/00
Filed: 1988-05-31
Abstract: PURPOSE:To obtain ceramic whisker having high quality and superior characteristics by causing the growth of the ceramic whisker by heating an SiO2/C compound starting material in nonoxidizing atmosphere. CONSTITUTION:An SiO2/C compound starting material obtd. by dispersing fine C powder in water glass, and treating the product with an acid, is heated in nonoxidizing atmosphere or in N2 stream at 1300-1800 deg.C to obtain thus aimed whisker after causing the growth of SiC whisker or Si3N4 whisker. A transition metal, an alkaline earth metal, or a compd. of the alkaline earth metal may be added as a third component to said SiO2/C compound starting material and may form a compound body at the same time, in order to prompt the generation of the ceramic whisker. The dispersion of fine C powder in the water glass can be performed by stirring and mixing. In this case, if the surface of the particles of the fine C powder is contaminated by oil film, etc., the dispersion may be insufficient due to decrease of the wettability of the C powder with the water glass, so sufficient dispersion may be easily attained if the C powder is wetted with an org. solvent such as alcohol, acetone, etc., before the addition of the C power to the water glass.

Title: Shield machine
Inventor: ABE SHIGEKI
IPC: E21D9/08
Filed: 1996-05-29
Abstract: PROBLEM TO BE SOLVED: To improve operation efficiency by constructing a succeeding tunnel parallelly with a preceding tunnel and disposing a water jet nozzle at a forward end of a skin plate, i.e., a part opposed to the outer wall surface of the preceding tunnel, so as to be oriented forward. SOLUTION: A lining body 21 of a succeeding tunnel 12 is constructed at the rear of a shield machine 13. Excavated earth and sand is discharged to the rear by means of an earth removal device 23. A water jet nozzle 24 is provided on each side of the device 23 so as to be oriented forward.

Filed: 1988-06-03
Abstract: PURPOSE:To reduce constant position deviation by switching a gain corresponding to whether the absolute value of position deviation is set inside or outside the prescribed range of position deviation for a targeted position. CONSTITUTION:When a mobile body 3 is moved linearly on a ball screw 1 by a motor 7, a pulse corresponding to the rotating speed of the motor 7 is outputted from a pulse generator 9 to a reversible counter 11, and is counted, and it is sent to a position control part 5 as the value P1 of the position of the mobile body 3. The position control part 5 fetches the position deviation e=P1-P2 from the value P1 and the fed back value P2 of the position of a following mobile body. A decision part 15 inputs the position deviation (e), and decides whether the absolute value ¦e¦ is inside or outside the prescribed range of the position deviation, and outputs a decided result to a gain switcher 16. The gain switcher 16 switches the gain to a prescribed value corresponding to the decided result.
