Title: Method for working ceramics
Inventor: TAKADA TERUAKI
IPC: C23D7/00
Filed: 1989-03-08
Abstract: PURPOSE:To facilitate finishing by heating the ceramics with which an article is coated at a low temp. to a half-cured state and finishing the ceramics, then heating the ceramics at a high temp. to cure the same. CONSTITUTION:For example, a disk rotor 1 body of a ventilated type is molded by casting of an Al alloy and machining of the casting thereof to an approximately disk shape. After the ceramics 2 is applied on both the side faces of the rotor 1 to serve as braking surfaces, the ceramics is baked at a low temp. of 150 to 200 deg.C to the half-cured state and this surface is subjected to surface finishing by a machining device. Since the ceramics 2 is in the half-cured state and is not completely cured, the easy machining is possible. The surface accuracy is improved by this surface finishing and thereafter, the ceramics 2 is backed at a high temp. of 400 to 500 deg.C and is thereby cured.

Title: Image forming device
Inventor: YAMAGUCHI YASUKI
IPC: B41J2/45
Filed: 1990-03-07
Abstract: PURPOSE:To shorten the length of a paper transportation path by forming an inclined surface which turns toward the shaft center of an image carrier between a developing part and an electrostatic charging part and at the lower edge of a substrate provided on a vertical plane which is offset to the developing part side from the shaft center of the image carrier and arranging many light emitting elements along the longitudinal direction of the image carrier on the inclined surface. CONSTITUTION:In an exposing part 3, the substrate 3a is provided on the vertical plane which is offset to the developing part 4 side from the shaft center of the image carrier 1, and the inclined surface 3b which is inclined at the angle of theta and turns toward the shaft center of the image carrier 1 is formed at the lower edge of the substrate 3a, then many light emitting elements 3c are arranged on the inclined surface 3b along the longitudinal direction of the image carrier 1. Therefore, an electrostatic charging part 2 is opposed to the outer periphery of the upper part of the image carrier 1, so that the substrate 3a is positioned closer to the developing part 4 side than the vertical surface passing the shaft center of the image carrier 1 and the light is emitted from the light emitting element 3c toward the shaft center of the image carrier 1 along the inclined surface 3b even when the posture of the substrate 3a is made vertical. Thus, the mounting space of the substrate 3a between the electric charging part 3 and the developing part 4 is reduced and the length of the paper transportation path is shortened and the device is miniaturized.

Title: Controlling system for page printer
Inventor: SUGIZAKI EIICHI
IPC: G06K15/12
Filed: 1985-03-19
Abstract: PURPOSE:To enable blank pages with arbitrary lengths to be provided on the upstream and downstream sides of a joint position, by a system wherein clock signals are supplied to the first counter set into a counting action by an output from a sensor for detecting a joint position and the second counter set into a counting action by an output from the first counter, and a writing operation is stopped and restarted by outputs from the counters. CONSTITUTION:The counter 31 is supplied with a clock signal from an output- controlling part 34 each time a paper 5 is fed forward by a predetermined length, so that feeding of the paper 5 by an amount equal to the distance between points A and E is detected by counting the clock signals after receiving a signal indicative of detection of a mark 52 from the sensor 4. At this time, a stopping signal is sent to the part 34 to stop writing of data from a page buffer 25. On receiving an output from the counter 31, the counter 32 starts counting, and after counting a number of clock signals corresponding to the process of providing the paper 5 with 4 blank pages, the counter 32 sends a starting signal for restarting the writing operation to the part 34. When the starting signal is received, writing of data from the page buffer at a writing point 8' is restarted. Accordingly, two-page amounts of blank parts can be provided on the upstream and downstream sides of the joint position of the paper 5.

IPC: B22D7/02
Filed: 1985-03-22
Abstract: PURPOSE:To obtain a composite iron or steel ingot having a defectless adhesion boundary by coating a core material with a wooden material and casting a base metal contg. components different from the components of the core material into a casting mold by bottom pouring so that the core material is insert- cast with the base metal. CONSTITUTION:Cardboard 10 is fixed by means of steel wires 11 to the surface of the core material 2 and further the cardboard 10' having the same thickness is superposed and fixed onto the head part side of the material 2 in order to compensate the decrease on combustion by radiation heat. A molten steel 6, when supplied from a ladle 9 into a pouring pipe 8, passes through a runner 7 from the pipe 8 and the molten steel 6 rises upward from below the casting mold 1 to insert-cast the material 2. The material 2 to be insert-cast is coated with the wooden material and therefore the wooden material is gassified and the scum is isolated from the surface of the core material. The composite metallic ingot having the defectless boundary between the core material and the base material is thus obtd.

Title: Preparation of 5-(1-cyanoethyl)-2-phenylthiophenylacetic acid ester
Inventor: ISHIDA RIYOUSUKE
IPC: C07B61/00
Filed: 1981-04-14
Abstract: PURPOSE: To prepare the titled compound useful as an intermediate for the preparation of antiphlogistics, economically, in high yield, without using expensive catalyst, by reacting a specific secondary halide with an alkali cyanide in the presence of a relatively inexpensive polyethylene glycol.  
     CONSTITUTION: The objective compound of formula II (R is alkyl) can be prepared by reacting 1mol of the 5-(1-haloethyl)-2-phenylthiophenylacetic acid ester of formulaI(X is halogen) with 1W3mol of an alkali cyanide in the presence of a polyethylene glycol (a liquid or solid compound having a molecular weight of ≥200, especially preferably 300W1,000, or if necessary, a solution of the compound in its solvent). The reaction proceeds using only a small amount of the alkali cyanide, and the cost for the treatment of the waste water containing cyanide can be saved. Since the relatively inexpensive polyethylene glycol is used as the reaction catalyst, and yet the yield of the process is higher than attained by the use of other expensive catalysts, the process is economical from the industrial view point.

Title: Laser welding method
Inventor: IWASAKI MASAO
IPC: B23K26/21
Filed: 1996-02-19
Abstract: PROBLEM TO BE SOLVED: To obtain a sufficient penetration depth and welding speed while increasing energy efficiency by arranging welding face with a prescribed angle for the laser irradiating direction. SOLUTION: Welding is executed by irradiating a first base metal 1a and second base metal 1b with a laser 3 of a laser beam welding machine having a lens 2. End faces 11a and 11b to be welded are made to tapered face, because the clearance between the first base metal 1a and second base metal 1b is not through along the irradiation direction of laser beam 3 and the laser beam 3 is completely received by the first bade metal 1a and second base metal 1b, there in so energy waste due to passing through of the laser beam 3. Also a welding end of one of base metals at least having difference in step in part is acceptable as well. By this method, passage of laser beam from the clearance between base metals is reduced or eliminated without needing high precision.
