Title: Driving mechanism for excavator
Inventor: KISHI MITSUHIRO
IPC: E02F9/12
Filed: 1981-01-31
Abstract: PURPOSE:To narrow an operating range of an excavator by a method wherein one end of a rotary body is pivotably secured in an eccentric manner to an upper surface of a vehicle body of an excavator used with excavation of road or the like a traversing stand, whereto an excavator is secured, is pivotably secured to the other end of the vehicle body, and the rotary body turns in synchronism with the slewing of the traversing stand. CONSTITUTION:One end of a rotary body 5 is pivotably secured in an eccentric position from a vehicle body center in a direction of a lateral width of a moving vehicle body 1 on the vehicle body 1, and traversing stand 6 is slewably secured above the other end of the rotary body 5. An excavating mechanism, such as a backhoe, provided with a bucket 14 is secured to the traversing stand 6. An inner gear wheel 8 in an arc of a circle, coinciding with the turning axial center of the rotary body 5 is fastened to the upper surface of the vehicle body 1, a revolving gear wheel 22, engaging the inner gear wheel 8, is set to the under of the traversing stand 6, and turns of the rotary body 5 and the traversing stand 6 are synchronized with each other through the working of the inner gear wheel 8 and revolving gear wheel 22. When the traversing stand 6 is positioned in a maximum eccentric location at one side of the vehicle body 1, a series of the operations causes positioning of the bucket 14 at the other side of the vehicle body 1, and thereby the bucket 14 is prevented from emerging from the side of the vehicle body 1.

Title: Reader for manuscript
Inventor: OZAWA TAKASHI
IPC: H01L27/146
Filed: 1982-01-29
Abstract: PURPOSE:To increase the sensitivity of an output from an image sensor by making the potential of a substrate a value the same as or less than the potential corresponding to the negative value of bias voltage when bias voltage is applied to one of two electrodes forming an photoelectric transducer and the other is switched by an N channel MOS transistor. CONSTITUTION:Photocurrents Ip flow through a constant-current source 19 by light irradiation under a state in which a gate 15 is brought to the negative potential of bias 10 and the N channel MOS transistor is turned OFF, signal charges are stored into a capacitance 20, and potential at a point A drops in the negative direction, but forward bias is not formed even when potential at the point A shifts because the anode of a diode 21 is connected to the negative pole of a bias electric wire 10, thus storing sufficient signal charges into the capacitance 20. Accordingly, output signals in the case when the gate 15 is brought to ground potential and the MOS transistor 5 is turned ON can be increased, the output is made linear to luminous energy, and the high-sensitivity reader extending over a high dynamic range is manufactured.

Filed: 1979-02-07
Abstract: PURPOSE: To prepare a title polymer without carrying out isolating operation by a method wherein hexachlorocyclotriphosphonitrile or a mixture of this nitrile and octachlorocyclotetraphosphonitrile is heated in paraffin.  
     CONSTITUTION: Hexachlorocyclotriphosphonitrile (3 PNC) or 3 PNC and octachlorocyclotetraphosphonitrile (4 PNC) is polymerized in the presence or absence of a catalyst in a paraffin solvent. The solid paraffin or liquid paraffin used is a good solvent for 3 PNC and 4 PNC, but a poor solvent for obtained phosphazene polymer, and hence said obtained phosphazene polymer is precipitated to a bottom of a reactor during reaction. Therefor, after reaction, polymer isolating operation is not required and this polymer is easily purified by a recrystallization method or the like.

Title: Recording medium
Inventor: KOJIMA AKIO
IPC: G11B7/241
Filed: 1990-01-25
Abstract: PURPOSE:To allow repetitive recording by providing an orientation control layer consisting of a material which is changed in wettability with water by photoirradiation on a substrate and providing a recording layer essentially consisting of a fatty acid or fatty acid deriv. in contact with this layer. CONSTITUTION:The crystal state of the part where heat is impressed changes when the thin film-like crystal of the fatty acid or fatty acid deriv. is used in the recording layer. Further, the orientability of the crystal is controlled by a difference in the wettability of the substrate with water, i.e., hydrophilic and hydrophobic properties. If the substrate is hydrophobic, the interaction with the carboxyl group of the fatty acid or fatty acid deriv. is weak and rotating motion is induced by a temp. rises so that the crystal orients perpendicularly to the substrate. The interaction of the carboxyl group is strong in the case of the hydrophilic substrate. The rotating motion is then regulated and the crystal is eventually oriented horizontally with the substrate. The crystals oriented perpendicularly and horizontally to the substrate vary in optical characteristics and the recording is executed on the basis of this change. The medium is reversibly changed in the crystal state of the material forming the recording layer by the impression of the heat energy in such a manner and, therefore, the repetitive recording is possible.
