Title: Production of polycarbonate
Inventor: KANEKO HIROAKI
IPC: B01J14/00
Filed: 1999-09-08
Abstract: PROBLEM TO BE SOLVED: To produce a polycarbonate having an improved hue and a reduced content of foreign matter by using an apparatus at least part of the inside surface of which is previously washed with a washing fluid containing a sulfur compound. SOLUTION: The sulfur compound that is desirably used is a thiol, a thioether, a thiocyanate, an isothiocyanate, a thioester, a thiourea, a thiocarbonate, or a disulfide. Although each of these compounds can fully exhibit its effect by itself, it is desirable in most cases because of easy handleability that each compound is used in the form of a solution or dispersion in a solvent. Although the amount of the sulfur compound used is not particularly limited, it is desirably in a concentration range from 1×10-6 to 30 pts.wt. per pt.wt. solvent. It is desirable that the apparatus is made of a metallic material being stainless steel. The production for producing the polycarbonate consists of transesterifying an aromatic dihydroxy compound with a carbonic diester compound in the presence of a catalyst.

Title: Dry type developing device
Inventor: TAKEDA KENICHI
IPC: G03G15/08
Filed: 1986-10-24
Abstract: PURPOSE:To suppress the dispersion of a developer due to the disturbance of the developer itself and to obtain the stable operation of a device for a long period by elastically contacting a continuous elastic sheet with a developer layer formed on the surface of a developer carrier. CONSTITUTION:When a sleeve 2 is rotated, a developer layer is magnetically restricted and held on the surface of the sleeve 2 and carried to a developing part (a) and a latent image on the surface of a drum B is successively developed with toner. In this case, elastic sheet members 14, 15 respectively corresponding to the upper and lower parts of the sleeve 2 on the left half side of the sleeve 2 which is exposed to the outside of a developer container 1 are softly face- contacted with the outside of a held developer layer. The outside of the held developer layer in an area under the sleeve arranged just before the residual developer layer passed through the developing part (a) enters from a gap part between a magnetic member 5 and the sleeve 2 into the container 1 is covered with a seal member 15. Consequently, the generation of toner dust from the developer layer area can be prevented.

Title: Breaker with protection of neutral wire open phase
Inventor: HOSHIKAWA TAKEYOSHI
IPC: H02H3/32
Filed: 1990-09-25
Abstract: PURPOSE:To provide possibility of checking the open phase protecting motion of a neutral line even under normal operation by connecting an impedance means having different impedance between two voltage lines and the neutral line, and thereby generating an unbalanced voltage state in the same as at the time the neutral line is in open phase. CONSTITUTION:When a neutral line 1c goes into open phase, the loads L1 and L2 become off equilibrium to cause either voltage to boost. This balanced voltage is divided and impressed on a terminal 8 of an integrated circuit IC, and is another terminal 2 generates an operational output. After a capacitor C3 as a timer is charged, a thyristor Th is turned on, and the output resistance value of a rectifier circuit 3 is lessened. A current is supplied to a trip coil Ry of a breaker, and its main contact RyS is opened, and the power to the loads L1, L2 is shut off. In testing, unequilibrium is generated on the voltages of resistances Z1, Z2 by turning on a test switch SW, and the main contact RyS is operated in the same manner as at the time the neutral line goes in open phase.

Title: Pencil for plotter
Inventor: KAMEI SHINYA
IPC: B43K21/033
Filed: 1995-09-06
Abstract: PROBLEM TO BE SOLVED: To prevent abrasion of the tip end of a lead guide by fixing a rigid pipe in an inner hole of the tip end part of a lead guide, and forming the rigid pipe tip end and lead guide tip end in generally the same plane. SOLUTION: A rigid pipe 11 consisting of rigid material such as ceramics is press-insertion fixed in the tip end hole 9A of a lead guide 9. Besides, the tip end of the rigid pipe 11 and tip end of the lead guide 9 are formed on generally the same plane. A spring 12 is spread over between the rear end of the lead guide 9 and the outer step 3B of a coupling piece 3 in order to urge the lead guide 9 in the longitudinal direction. Weaker repulsive forces of the spring 12 than the lead retaining forces of the lead holder 10 may be preferable because they prevent the unnecessary forward of the lead guide 9 as the plotter pencil rises. Although rigid material such as ceramics is employed for material of the rigid pipe 11, ceramics consisting of zirconia or alumina may be preferable in aspects of an abrasion resistive property and productivity.

Title: Method for supplying slurry
Inventor: ODA KAZUO
IPC: H01F41/12
Filed: 1996-09-26
Abstract: PROBLEM TO BE SOLVED: To provide a method for stably supplying slurry into a metallic forming mold by using a fixed delivery pump. SOLUTION: The slurry 1 is charged into a slurry vessel 2, and the top part of suction of a 'Moineau pump(R)' 3 is inserted to near the bottom of the slurry vessel 2. The 'Moineau pump(R)' 3 is rotated, and the production of solvent puddle in the slurry is prevented by exciting the slurry vessel 2 at the same time of supplying. On the other hand, when supplying the slurry with repeated exciting for long time, the concn. of fine powder for magnet at the tip part of suction of the 'Moineau pump(R)' is increased and at the time of executing the supplying at the same number of rotations, the supplying quantity of the fine powder for magnet into the metallic mold is gradually increased.  Then, the change of this supplying quantity is taken as the height change of a formed body, and the number of rotations of the 'Moineau pump(R)' 3 is corrected from a deviation to a target value, thus the formed body having always fixed height is attained.

Abstract: PURPOSE: To eliminate formation of a side wall required for forming an LDD region by providing a resist having a pattern corresponding to the source-drain region and implanting impurities into a source-drain forming region thereby corroding the resist side wall of the pattern through isotropic etching. CONSTITUTION: A gate insulation film 11 and polysilicon 12 are deposited on a semiconductor substrate 10 and a photoresist 13 is formed thereon.

Subsequently, impurity ions are implanted into the source-drain forming region using the resist 13a as a mask thus forming a source-drain diffusion region 20. Finally, side wall of the resist 13a is corroded through isotropic etching and the polysilicon 12 is patterned using a thinned resist 13b as a mask to form a gate electrode 15 before impurity ions are implanted to form an LDD region 21.

SOLUTION: A mixed gas supply system 16 supplies at least three kinds of film-forming gases. A supply source 16A supplies a silicon-based material gas or a silicon-based liquid source (SiCl4), including on hydrogen into a processing chamber 11, a supply source 16B supplies a silicon-based oxidizing material gas (N2O) which does not include hydrogen, and a supply source 16C supplies a nitrogen monooxide gas (NO) to form an oxynitride film by a CVD method. Accordingly, a bond related to hydrogen such as-H group,-OH group or the like or a bond related to hydrogen such as Si-H bond, Si-OH bond, N-H bond or the like is not substantially included by a film. This eliminates heat treatment process to remove a bond group after forming the film and hence enables reducing the number of manufacturing processes and to adopt process for producing low temperature.
