Title: Process for the direct production of captopril
Inventor: ANDERSON NEAL G
IPC: A61P9/00
Filed: 1990-11-05
Abstract: A process is disclosed for direct isolation of captopril from a substrate of the formula <CHEM> wherein R is lower alkyl or lower alkoxy. In this process, the substrate is first treated with an aqueous alkali metal hydroxide capable of forming a water-soluble salt of the substrate, wherein the alkali metal hydroxide has a concentration of 4 M or greater. The substrate is then neutralized, preferably with a mineral acid. By this process, captopril may be directly crystallized from an aqueous solution, avoiding the prior art use of organic solvents and zinc treatment to reduce levels of sulfide and disulfide impurities, respectively. In an alternative embodiment, neutralization is carried out by use of a hydrogen-supplying ion exchange resin.

Inventor: PARKER MICHAEL PATRICK
IPC: B60B37/10
Filed: 1998-12-04
Abstract: A rigid of smoking articles is made to have improved shelf life and to be resealable. A barrier material is sealed around the rigid pack. The rigid pack has a potential or actual access aperture extending from a top face into a major face. The barrier material has a line of severance or weakening defining a flap, which is in register with the potential or actual access aperture. Over the flap is a layer which overlaps it on each severable side with a portion having permanently-tacky adhesive. A non-adhered pull tab is preferably provided on the layer. To open the pack the user lifts the flap and if necessary the access aperture.

Title: Controller of power converter
Inventor: INOUE NAOKI
IPC: H02P27/02
Filed: 1998-01-06
Abstract: PROBLEM TO BE SOLVED: To suppress transient current, by turning a switching element in a conducting state to a non-conducting state when a timing signal is outputted, then intermittently turning a switching element in a non-conducting state to a conducting state until a short-circuit preventive signal is stopped, and then keeping it in a conducting state. SOLUTION: An equipment has a timer 21 which outputs a timing signal having a pulse width corresponding to the set period of time on reception of a control command for snitching elements 3, 4 from a speed controller. When a timing signal is outputted from the timer 21, the switching element 4 in a conducting state is turned to a non-conducting state, and the switching element 3 in a non-conducting state is intermittently turned to a conducting state until a NAND circuit 23 stops the output of a short-circuit preventive signal, and then is kept in a conducting state. By this method, large transient current is prevented from flowing in coils of a three-phase motor when the switching element is turned from a conducting state to a non-conducting state, while shorting of a power supply is being prevented.

Title: Method of producing material for shadow mask
Inventor: KUBOTA MASAROU
IPC: C21D9/46
Filed: 1978-01-10
Abstract: PURPOSE:To provide a material for shadow mask with improved resistance to stretcher stylene and press workability by rolling a hot-rolled low carbon rimmed steel plate containing a specified amount of C and S to a desired thickness through a primary cold rolling, a secondary cold rolling after a decarburization annealing and a rolling after non-decarburization annealing under a prescribed condition. CONSTITUTION:A hot-rolled steel plate made of a low carbon rimmed steel containing 0.03 to 0.10% of C and 0.014% or less of S undergoes a primary cold rolling via the normal process and is subjected to a decarburation annealing in an open coil annealing furnace under a wet hydrogen atmosphere to reduce C to 0.005% or less. Successively, following a secondary rolling, it undergoes non-carburization annealing above the recrystalization temperature but below 600 deg.C and futher is cold-rolled to a desired thickness with a cold rolling rate of over 10 to 25% to produce a steel strip for shadow mask. Providing a photo-etching hole on the steel strip can produce a material ideal for shadow mask with a press forming eliminating annealing and leveller treatment.

Title: Method and device for establishing synchronization
Inventor: TAKAHASHI NAOMICHI
IPC: H04B1/7075
Filed: 1990-01-10
Abstract: PURPOSE:To enable accurate demodulation by observing a correlation peak for N cycles of a code sequence and generating a cycle signal so that the position of the correlation peak whose synchronized state is decided is in the center of a cycle of the code sequence. CONSTITUTION:A detecting circuit 26 detects the correlation peak position of the correlation signal between a reception signal and the code sequence with specific length for N continuous cycles in each cycle of the code sequence. A decision circuit 27 decides which of divided areas the detected peak position belongs to in one cycle and a counting circuit 28 counts detected peaks belonging to each area. Then an m/N decision circuit 29 decides whether or not the detected peak counted value of one of the areas reaches a specific number (m) in N cycles and considers that synchronism is established when the specific number (m) is reached. The cycle signal is so generated that the peak position reaching the specific number (m) is in the center of the cycle of the code sequence. Consequently, the accurate demodulation is performed.

Title: Determination of ammonia in excess mea sample
Inventor: MITSUOKA SHIGEAKI
IPC: G01N30/12
Filed: 1994-01-13
Abstract: PURPOSE:To determine ammonia accurately by distilling a sample containing monoethanol amine excessively, absorbing the evaporated ammonia into a boric acid solution and separating the ammonia by cationic chromatography. CONSTITUTION:When a sample containing monoethanol amine (MEA) excessively is distilled, an alkaline substance, e.g. sodium hydroxide or magnesium oxide, is added in order to prevent decomposition of MBA and ammonia is evaporated thermally. The evaporated ammonia is absorbed into a boric acid solution and an acid solution, e.g. a sulfric acid solution, a hydrochloric acid solution or an organic acid solution, may be used alternatively. The cationic chromatograph uses a sulfonated polystyrene-based cationic exchange column, for example, and the concentration of ammonia is determined by peak area method according to a predetermined working curve.
