Title: Preparation of nitrile
Inventor: FUKUOKA SHINSUKE
IPC: B01J23/18
Filed: 1980-02-18
Abstract: PURPOSE: To obtain a nitrile in high yield and selectivity, by treating an N-monosubstituted formamide in the presence of a catalyst selected from a specific oxide and silica gel and a gas containing oxygen at a specific temperature.  
     CONSTITUTION: An N-monosubstituted formamide, e.g. N-methylformamide, of the formula R-(NHCHO) n  (n is an integer 1W3; R is an n-valent organic residue) is treated in the presence of a catalyst consisting of one or two or more oxides, e.g. molybdenum oxide or tungsten oxide, of a metal selected from Groups V and VI in the periodic table, and a gas containing oxygen, e.g. air, at 300W600°C to give a nitrile. The resultant nitrile is convertible into a primary amine readily by the reduction with hydrogen. Thus, the method used in an intermediate step provides a primary amine having one more carbon atoms that a primary amine readily.

Title: Box clogging detecting device in box transfer device
Inventor: NISHITANI YOSHINOBU
IPC: B65G43/02
Filed: 1989-01-27
Abstract: PURPOSE:To prevent excessive supply of supplies to box bodies in the captioned device for seedling culture boxes, etc., by installing a rotating body which rotates together with the box body transfer, pressed against the box body, and a detector which detects the stopping and slowdown of the rotating body, and stopping the box transfer with detected signals. CONSTITUTION:When a rubber roll 38 is pressed against a seedling culture box 2 which are supplied in succession, the rubber roll 38 rolls in B direction. If the transfer of the seedling culture boxes 2 is suspended due to the clogging of the seedling culture boxes 2, a oneway culture 39 which has been in a free state is engaged to create driving force to rotate the rubber roller 38 toward B direction since a motor 42 continues its rotation in D direction at its specified speed. Since the seedling culture box 2 is then suspended, the motor 42 oscillates around a projected shaft 43 by its reaction to actuate a detection switch 45, which stops respective devices. This constitution prevents excessive supply accompanying the suspension of seedling culture boxes.

Title: Induction motor controller
Inventor: SHIMIZU ICHIROU
IPC: H02P23/07
Filed: 1979-02-20
Abstract: PURPOSE: To reduce the primary terminal voltage rise of an induction motor in a field-weakening control range for controlling the motor in constant output operation by adding a function generator receiving the absolute value of a rotational angle speed as an input to the motor.  
     CONSTITUTION: Instantaneous primary current standard value to be supplied is calculated by the torque instruction value and the magnetic flux instruction value on the basis of the mutual inductance value between primary and secondary windings of a motor IM, self-inductance value of the secondary winding and resistance value of the secondary winding to control the vector of the motor IM with a frequency converter 1. At this time a function generator 22 receiving only the absolute value of the rotational angle speed of the motor as an input is added to the motor. Thus, the magnetic flux is weakened inversely proportionally to the speed of the motor to predetermined speed, and less weakened than the inverse proportion to the speed after the motor is rotated at higher than the predetermined speed. Accordingly, it can reduce the primary terminal voltage rise of the motor IM in all field magnetic flux weakening range to safely insulate the induction motor.

Filed: 1995-02-07
Abstract: PURPOSE: To improve re-startability of an engine especially on warming-up operation by controlling a fuel injection valve so as to supply a prescribed amount of fuel before the engine becomes the same in speed as just before stop after arranged for stopping. CONSTITUTION: When an engine 1, while rotated, is arranged for stopping and turns off an ignition key, ignition by an ignition plug 7 is immediately stopped by an ECU 30. Until engine rotating speed detected by an engine rotating speed detecting sensor 33 is reduced to engine stop just before rotating speed after engine stop operation is carried out, fuel injection is continued by an injector 12, and fuel injection is stopped when engine rotating speed is reduced to engine stop just before rotating speed. When the engine operation is re-started, fuel which is sumped in an intake system is absorbed and led into a combustion chamber, and mixture in the combustion chamber becomes an air-fuel ratio which is immediately enabled ignition after re-starting operation. It is thus possible to improve re-startability of the engine 1.
