Abstract: PURPOSE:To obtain the titled compound useful as a surface active agent, etc. in high yield, by reacting an N<omega>- or N<alpha>-acyldiaminomonocarboxylic acid with formic acid or a formaldehyde in the presence of a specific amount of an alkali substance. CONSTITUTION:An N<omega>- or N<alpha>-acyldiaminomonocarboxylic acid shown by the formula I or formula II (RCO is 8-22C aliphatic acyl; n is 2-4) is reacted with formic acid and formaldehyde and/or paraformaldehyde in the presence of 0.1- 1.0mol equivalent of alkali substance (e.g., NaOH) based on 1mol formic acid to give the desired substance shown by the formula III or formula IV. In the reaction, side reactions are suppressed to the utmost by using a mixed solvent of water and a hydrophilic organic solvent (e.g., N,N-dimethylformamide), and the reaction is advanced smoothly by the existence of the alkali substance. An alkali formate in a given ratio may be used instead of formic acid and the alkali substance.

Title: Inspecting and calibrating method of fluid pressure sensor
Inventor: AKAISHI NORIO
IPC: G01L27/00
Filed: 1988-08-31
Abstract: PURPOSE:To dispense with special equipment such as a pressure regulating chamber or the like and to enable easy execution of detection and calibration by a method wherein a weight giving an amount of deformation being equal to the one caused by a fluid pressure being used is made to act on a deformation output element of an atmospheric pressure detecting means. CONSTITUTION:In an atmospheric pressure sensor 1, an output circuit is constructed so that an output voltage varies linearly in relation to a change in an atmospheric pressure. While a reference output curve of the sensor 1 is shown by a curve C, it is indefinite actually as shown by curves A and B. After assembling, therefore, an adjusting screw 24 is adjusted under a standard pressure to shift the curves A and B in the direction of a longitudinal axis and thereby to output an initial output V0. Accordingly, the curves A and B turn to be A' and B' respectively. In order to make the curves A' and B' coincide with the curve C, subsequently, a weight 34 weighing corresponding to a barometric pressure 500mB equals to 5,000m above sea level, for instance, is given to the sensor 1, and an output voltage is made to coincide by adjusting a variable resistor 33. Thereby an output curve can be made to coincide with the curve C irrespective of nonuniformity of a spring constant of an atmospheric pressure detecting means 2. Berside, an auxiliary weight 48 is used for correcting the gravity of the weight.

Filed: 1982-12-09
Abstract: PURPOSE:To eliminate substantially the level variance of an output terminal within the switching transient time of a switch of a synthesizing circuit, by setting the resistance value of a resistor connected in series to the switch at a level sufficiently larger than the impedance of an input terminal and sufficiently smaller than the impedance of an output terminal, respectively. CONSTITUTION:When the input level difference is approximately zero, switches 11 and 13 are turned on. An equivalent circuit of this case is shown in a diagram (a), where V1 and V2 show the output voltage of amplifiers 20 and 21, respectively, r1 is the input impedance of an amplifier 22, r2 is the output impedance of amplifiers 20 and 21 and Vout shows the voltage that is applied to the input of the amplifier 22. If r1>R>r2 is satisfied, Vout (v1+v2)/2 is obtained. Then the switch 11 is turned off when the input level of a receiver is greatly reduced and the S/N improvement quantity is negative. In this case, the output levels have coincidence like the case of the diagram (a). The transient level variance due to the characteristics of the switch 11 is not generated also within the transient time from the diagram (a) to (b).

Abstract: PROBLEM TO BE SOLVED: To prevent breakage of a device and another sheet clogging due to a torn sheet piece following occurrence of sheet clogging in a route to carry a sheet. SOLUTION: Supply of a sheet 3 to a sheet cassette 4 is under a front loading method. A switch-back route 17 is branched on a carrier route 16 to carry the sheet 3 to a picture image forming part 2 from the sheet cassette 4.

A fixing sensor 35 detects occurrence of sheet clogging on a fixing device 12. Driving of a picture image formation device 1 is stopped at the time when sheet clogging occurs. However, the sheet 3 being carried in a carrier route 18 connecting the sheet cassette 4 and the switchback route 17 to each other is stored in the switchback route 17 by maintaining sheet carriage.

Abstract: PURPOSE:To save the power consumption by providing a resistor connected in parallel with a detection diode inserted into a return current path in the forward polarity and a bias current source supplying a backward current of the detection diode to the parallel circuit comprising the resistor and the detection diode. CONSTITUTION:A DC return current IR of PIN diodes 31, 32 flows to a DC return current path 33 comprising a detection diode 30 and an RF coil 25 and does not almost flow to the 2nd resistor 27.

Thus, the power consumption of the bias current source 34 is improved.
