Title: Denitration of organic nitric acid ester
Inventor: SETSUDA TSUTOMU
IPC: C07C29/12
Filed: 1981-06-22
Abstract: PURPOSE: To carry out the denitration reaction of an organic nitric acid ester, without using complicated operations or external energy source, by the hetero- phase treatment of a hydrophobic phase containing said ester with an aqueous liquid phase containing the hydrosulfide, sulfide or polysulfide of ammonium or alkali metal.  
     CONSTITUTION: A hydrophobic liquid phase especially chlorinated hydrocarbon solution containing ≤80wt%, especially ≤60wt% organic nitric acid ester is subjected to the hetero-phase treatment with an aqueous liquid phase (aqueous solution) containing a sulfur compound selected from the hydrosulfide, sulfide and polysulfide of ammonium and alkali metal, especially a sulfide such as sodium sulfide, in the presence of preferably the hydroxide of ammonium or alkali metal and/or a phase-transfer catalyst at preferably 40W100°C. The denitration reaction proceeds quantitatively at the interface of the liquid phases, and the organic component and the inorganic component of the reaction product are essentially completely partitioned between both phases.

Filed: 1987-04-20
Abstract: PURPOSE:To form a multicolor image of high quality by providing a means which delays and adjusts the transmission timing of a horizontal synchronizing signal. CONSTITUTION:A waveform shaping circuit 1 shapes the waveform of the light quantity signal of a laser beam detected by a beam detector 5 and outputs a horizontal synchronizing signal BD1 for determining the image recording start position of a photosensitive drum Dr. A waveform shaping circuit 2 shapes a light quantity signal detected by a beam detector 6 at a position precedent to the detector 5 in the main scanning direction of the Dr and inputs a pulse signal PBD2 for generating a horizontal synchronizing signal DB2 at timing precedent to the signal BD1 to a one-shot circuit 3a and outputs an adjusting pulse 3c to a one-shot circuit 4 in synchronism with the signal PBD2. A pulse width adjusting device 3b adjusts the pulse 3c to adjust the detection time lag of a laser beam scanned in the relative arrangement distance difference area between the detectors 5 and 6 so that the signal PBD2 synchronizes with the leading edge of the signal BD1. Consequently, the multicolor image of high quality is formed.

Title: Flow speed sensor driving system
Inventor: HIKITA TSUTOMU
IPC: G01P5/12
Filed: 1986-04-23
Abstract: PURPOSE:To measure the speed of a fluid under low power consumption, by a method wherein a bridge is constituted of first and second thermometric resistors having the same temp. coefficient and the output thereof is differentially amplified to heat the second thermometric resistor and the power source of the bridge and a differential amplifier is opened and closed. CONSTITUTION:If no heat is generated from RH of a resistor 9, the temp. change of Rf of a thermometric resistor is same to that of RS of a thermometric resistor 7 and voltage v2-v1 does not change. When a flow speed increases and the quantity of heat removed from RS increases, v1 is reduced and v2-v1 increases. Because feedback is applied to the whole of a circuit so as to brought v2-v1 to 0, the heat generated from RH increase by an increase in differential output v0, and RS is heated to increase a resistance value and v2 rises while v1-v2 comes to an equilibrium state and the flow speed can be measured from the output v0 of a differential amplifier 8. If a switch element 2 is closed for a short time only when the flow speed is measured and v0 is read by a sample extraction means, the flow speed is measured with high accuracy and power consumption is also reduced.

Filed: 1988-04-19
Abstract: PURPOSE:To realize stable ink ribbon feed in response to speed regardless of a change in manual sub-scanning speed and thereby make handling easy with features such as compactness, light weight, low cost and high printing quality by providing a structure which allows the rotation of a travelling roller to be friction-transmitted to a winding ink ribbon roll for taking up an ink ribbon through an elastic member. CONSTITUTION:The rotation of a travelling roller which is transmitted to a contact member 3 for a winding ink ribbon roll 1 through a rotation transmitting member 4 for the travelling roller and a coil spring 2, is transmitted to the winding ink ribbon roll 1 by friction force between the contact member 3 for the winding ink ribbon roll and the winding ink ribbon roll 1. The friction force is generated by the elastic force of the coil spring 2 as a resisting force. The used portion of an ink ribbon is taken up uniformly by the winding ink ribbon roll 1 while receiving the twisting moment of the coil spring 2 and friction force. As the ink ribbon is wound, the diameter of the ink ribbon roll 1 becomes gradually large. However, due to the employment of frictional transmission of rotation, the feeding speed of an ink ribbon is not directly affected.

Abstract: PURPOSE:To easily discriminate left and right printed photographs even in the case that the left and right printed photographs ae scattered. CONSTITUTION:As to the stereoscopic camera for photographing an object by a pair of left and right photographic lenses 10L and 10R and simultaneously imprinting respective images on two frames of a film, a character showing the identification of left and right printed photographs is simultaneously imprinted on each frame of the film with the object image.
