Title: Preparation of pheophytin
Inventor: IRIYAMA KEIJI
IPC: C25B3/00
Filed: 1979-02-21
Abstract: PURPOSE: To selectively convert the chlorophyll film on the chlorophyll-coated electrode to pheophytin by performing the electrode reaction of said electrode in an acidic electrolyte.  
     CONSTITUTION: As an electrolytic supporting solution in electrolyte, a 0.2N aqueous potassium chloride solution or the like is used and its pH is controlled to 2.2W6.0 by using a phosphoric acid-citric acid buffer solution or the like. When a potential of about -0.2VW+5V is applied between the chlorophyll-coated electrode and reference electrode in this electrolyte, dark current flows between the both electrodes. When light radiation is further performed, the flow of photo current is observed. At this time, the chlorophyll film on the electrode becomes pheophytin through electrode reaction. The rate of this reaction is accelerated by light radiation. The coated electrode is taken out after the end of the reaction and the film is dissolved in an organic solvent. Thence, the organic solvent is removed and is separated to chlorophyll and pheophytin by a chromatography method, whereby pheophytin is isolated.

Filed: 1994-02-17
Abstract: PURPOSE:To simplify a configuration by employing a high pass filter for a feedback circuit of an integration device and to improve the characteristic of the circuit by connecting a low pass filter in cascade to an output of the integration device. CONSTITUTION:An analog signal received by an input terminal 102 is integrated by an integration device 101 using an n-degree high pass filter for its feedback circuit. An output of the integration device 101 is band-limited by a low pass filter 106. An A/D converter 109 converts an output of the low pass filter 106 into a digital signal, which is outputted to an output terminal 110. Furthermore, a delay device 111 delays the digital signal being an output of the A/D converter 109 by one sampling period. A D/A converter 112 converts an output of the delay device 111 into an analog signal. The analog signal is fed back to an operational amplifier 104 via a feedback resistor 113, and the circuits above form an n-degree noise shaping circuit. A level detector 114 detects whether or not an output of the filter 105 has a level at which the circuit system is unstable or over and a changeover device 115 switches the degree of the high pass filter 105 from the n-degree into the 2nd-degree.

Title: Method for improving fatigue strength of structural stress concentrating part
Inventor: SAKANO KENJI
IPC: B23K9/00
Filed: 1995-02-08
Abstract: PURPOSE: To surely take a measure for improving the fatigue characteristic by developing the residual compressive stress in a stress concd. part with a welded bead formed on the surface of a structure. CONSTITUTION: The welded bead 7 is formed on the surface of the structure (metallic plate) forming the stress concd. part A at the specific position by repeated tensile force 5 to develop the residual compressive stress in the stress concd. part A with this operation. The welded bead 7 is formed with the ordinary welding means by using a welding material having higher strength than the structural material of the structure 1. The welded bead 7 is parallel formed with the tensile stress 6 separating an interval (h) from the stress concd. part A and developed in the stress concd. part A. The interval (h) can be e.g. 1-3 times of the width of the welded bead 7 or 1-3 times of the plate thickness to the structure 1 so as to form the residual compressive stress in the stress concd. part A. The welded bead 7 can be linear state as parallel with the tensile stress 6.  By this method, the fatigue characteristic (strength/service life) from the stress concd. part can be improved.

Title: Device for detecting operation of plunger
Inventor: ARITAKA AKITOSHI
IPC: G06F3/13
Filed: 1983-02-08
Abstract: PURPOSE:To detect the operation of a plunger for a short time by detecting the change of current flowing into the plunger. CONSTITUTION:When a control input is applied to a driving circuit 1, a transistor (TR) starts to operate and current is made flow into the plunger P. The current is converted at its voltage by a resistor R1. The current is delayed by its self-induction. When the internal iron core of the plunger P starts to move, inductance L is increased and the self-induction is also increased, so that current is reduced. When the attraction operation of the plunger P has been completed, the increment of the inductance is stopped and the current is increased again. Thus, the operation of the plunger P can be found by detecting a dip point from the increase/decrease of the current.
