Abstract: A chemical composition for use in the papermaking process to produce a paper having enhanced characteristics of brightness, opaqueness, and sizing is provided. The process using the composition to make the paper and the paper made therefrom are also provided by the present invention. The composition is made by combining an amphoteric softener such as a salt of an amphoteric stearic acid derivative, a cationic softener base, such as the mono- and distearamides of aminoethylethanolamine, an acid, such as acetic acid, a surfactant, such as POE (15) tallow amine, carbamide, and water. In another embodiment, a saccharide may be employed instead of the amphoteric stearic acid derivative, surfactant and carbamide. To speed the production of the composition, a viscosity controlling agent, such as sodium chloride or sodium acetate, may be added thereto. The composition is added to pulp slurry during the papermaking process, and a paper made therefrom exhibits excellent qualities of brightness, opaqueness, water repellency, and dispersibility.

Title: The preparation of penicillin sulfoxide
IPC: C07D499/04
Filed: 1973-08-24
Abstract: 1388979 Preparing penicillin sulphoxides ELI LILLY & CO 21 Aug 1973 [12 Sept 1972] 39603/73 Heading C2C Penicillin sulphoxides are prepared from a penicillin-containing fermentation broth by filtering off the mycelium and adding a miscible organic liquid to the filtrate to precipitate non- penicillin impurities, oxidizing the penicillin in the solution with a per-acid oxidizing agent at -20 to 25 C., to produce the sulphoxide, lowering the pH of the resulting solution and adding water to induce crystallization of the sulphoxide, and separating the crystallized sulphoxide from the supernatant. The filtered broth containing the penicillin (e.g. phenoxymethyl- or benzyl-penicillin), is preferably concentrated to 200-400 mg. solid per ml. before adding the organic liquid, which is preferably acetone in ¢-3 volumes or may be methanol, ethanol, methyl ethyl ketone, acetonitrile, isopropanol, tert.-butanol or propionitrile. The precipitated impurities are usually filtered off, and if desired the organic liquid may then be removed. Oxidation is effected with an at least partially soluble oxidizing agent, in sufficient amount to convert all the penicillin content to the sulphoxide, e.g. 1-3 moles per mole of penicillin; the preferred agents are per-acetic acid, per-propionic acid, per-benzoic acid and per-succinic acid. The pH is then lowered to a crystallization point of the penicillin (i.e. about the iso-electric point), usually about pH 1À5-2À5, preferably with one of the following: methanesulphonic, p-toluenesulphonic, hydrochloric, sulphuric, o-phosphoric or nitric acid, and water is added to assist crystallization. The penicillin oxide crystallizes in pure form and is separated from the supernatant liquid.

Title: Infrared detecting device
Inventor: MATSUDA HIKARI
IPC: G01S3/789
Filed: 1989-01-19
Abstract: PURPOSE:To cover a wide azimuth angle by a small number of cameras by shifting the orientation directions of infrared cameras stepwise almost by a field angle. CONSTITUTION:Incident infrared rays 1 arrives almost horizontally from a distance point and is bent by a mirror 2 almost at right angles to form an image on a two-dimensional photoelectric converting element 4 through an infrared lens 3. Then an element driving circuit 5 controls the element 4 to store a signal in a fixed direction for a specific time and an incident infrared- ray image signal is converted into a serial video signal, which is outputted to an automatic detecting circuit 7 through an amplifying circuit 6. Here, the circuit 7 emphasizes and amplifies a relatively small target in an image plane and detects the target automatically by threshold detection. When an image in a certain direction is extracted, a mirror swivel rotating mechanism 8 directs the camera to a next cover area and swivels the mirror 2 by a specific angle. Thus, the cover areas of a small number of sensors are shifted stepwise to cover the entire direction on a time-division basis to reduce the size of the device.

Title: Pseudo fault generating system for communication controller
Inventor: KATO TAKAO
IPC: H04L69/40
Filed: 1986-01-21
Abstract: PURPOSE:To produce a pseudo fault by a program with no intervention of a manual operation by using a pseudo fault generation indicating register and a coincidence detecting circuit which checks the coincidence between an optional part of the received data and the pseudo fault generation data. CONSTITUTION:The data received by a receiving circuit 201 via a transmission line 702 is sent to a coincidence detecting circuit 202 for pseudo fault generation data. Then an optional part of the received data designated by a pseudo fault generation indicating register 205 is compared with the comparison data designated by the register 205. If no coincidence is obtained between both data or the n-th designation of the register 205 is not available, the circuit 202 gives an indication to a response generating circuit 207 to generate a response. Thus a puseudo fault is produced when (n) times of coincidence are obtained between an optionally designated part of the received data and the pseudo fault generation data.

Title: Manufacturing method for color cathode-ray tube
Inventor: KAKO HIDEKAZU
IPC: H01J9/385
Filed: 1982-01-28
Abstract: PURPOSE:To reduce the incidence of the crack of a glass bulb and improve the electron emission characteristics of an oxide cathode by specifying the maximum heating temperature of the glass bulb that forms an enclosure. CONSTITUTION:In the exhaust process of a cathode-ray tube, the heating temperature of a glass bulb that forms an enclosure is set in 250 to 300 deg.C at a maximum. Since gases such as H2O, CO2, CO, or the like are discharged slowly during exhaust by decreasing the heating temperature of the glass bulb, as compared with the conventional heating temperature, a great amount of gas remains residual in the tube even after exhaust. In such a condition, hydrocarbon is generated on a (Ba) coat by flashing a getter. This hydrocarbon  touches the surface of a heated oxide during cathode aging and carbon is sedimented on the surface of the oxide after it is dissolved. Since the activation of an oxide layer continues for a long period of time like this, emission life can be improved.
