Title: Production of pyridineborane
Inventor: HORI BUNJI
IPC: C07F5/02
Filed: 1993-07-20
Abstract: PURPOSE:To produce pyridineborane in high yield while suppressing an amount of pyridine used as a solvent to low value. CONSTITUTION:In producing pyridineborane from pyridine, sodium borohydride and a mineral acid, sulfuric acid having >=36wt.% concentration is used as a mineral acid and sodium borohydride and sulfuric acid are added to pyridine little by little and the reaction is carried out at -5 to 50 deg.C, preferably 0-40 deg.C. In the reaction, pyridine as a raw material also plays the role of a solvent in first half of the reaction and pyridineborane of the reactional product mainly plays the role of the solvent in the latter half of the reaction. As a result, pyridine as the solvent can be used in a smaller amount, compared with conventional technique and stirring is readily carried out and efficiency of the reaction can be raised. because the reactional system can be kept as a liquid phase state from the start to the end of the reaction.

Title: Process input gathering device
Inventor: KAMENO OSAMU
IPC: G05B15/02
Filed: 1982-11-19
Abstract: PURPOSE:To gather data in a high speed, by discriminating the threshold value of an input value and holding this value, and adding information by which holding and holding reset are discriminated to data. CONSTITUTION:Transitional data generated from each measuring point of a plant is gathered by each analog input device 2. These analog data are converted to digital quantities by converters 3, and their threshold values are detected by maximum and minimum detecting devices 4. It is discriminated in an extreme value generation detecting device 5 whether these extreme values exceed a limit value or not. When the extreme value exceeding the limit value is detected by the device 5, a signal A is sent from the device 5 to an operating device 7. When receiving the signal A, the device 7 holds threshold values, which are stored in devices 4 beforehand, in a data holding device 6. When the device 7 does not receive the signal A, the device 7 performs another processing and takes in data simultaneously with signal reception. Thus, only normal threshold values are stored in a storage device 8. A reset signal B is sent only to devices 6 where extreme values are held.

Filed: 1988-08-12
Abstract: PURPOSE:To realize correct measurement of temperature, etc. by providing an adjusting means in a driving circuit for adjusting a driving signal such that the amplitude of a vibrating body is restrained from changing in corresponding to the change of an environmental temperature. CONSTITUTION:A diode 50 and a transistor 52 constituting a stabilized power circuit 53 for a driving circuit 41 have a minus temperature between an emitter and a base thereof. Accordingly, an absolute value of an output voltage -Vc volt represents a negative temperature characteristic. In this case, the power circuit 53 together with an infrared detector 1 including vibrating bodies 24, 25 is present within the same casing 42. Therefore, the negative temperature characteristic of the absolute value of the output voltage -Vc volt in the power circuit 53 is substantially corresponding to the same environmental temperature as the vibrating bodies 24, 25. Accordingly, even when the environmental temperature changes and the absolute value of the output voltage -Vc volt changes, a temperature signal outputted from an output terminal 63 is constant. That is, although the amplitude of the vibrating bodies 24, 25 might vary, it is restricted before it happens. Therefore, the temperature measurement does not result in an incorrect value.
