Title: Horizontal rotary compressor
Inventor: SUGIYAMA MASAHIKO
IPC: F04C29/04
Filed: 1984-07-13
Abstract: PURPOSE:To lead discharge gas into a radiator in case of high temperature, bringing its compressor cooling function into full play, and make a refrigerant dischargeable directly to the inside of a case in case of low temperature, by attaching a bypass valve, consisting of a platelike form memory alloy, to part of a discharge silencer. CONSTITUTION:A discharge silencer 32 and a vent hole 30a to be interconnected to an internal space of a case 1 are installed in a platelike discharge valve cover 30, and a bypass valve 31 formed with a plate material of a reversible form memory alloy in a form capable of closing the hole 30a from one side is engaged there by a bolt 34. At normal temperature or less, as shown in a full line, the bypass valve 31 is of a convex form to the discharge valve cover 30 so that high temperature and high pressure refrigerant gas 20b out of the vent hole 30a is directly discharged to the inside of the case 1, keeping off its overcooling, thus any drop in cooling capacity is preventable from occurring. On the other hand, in time of high temperature, the bypass valve 31 comes to a concave form, closing the vent hole 30a, so that the high temperature and high pressure refrigerant gas 20 is led into a radiator 21 by way of a connecting pipe 18, bringing its compressor cooling function into full play.

Title: Electromagnetic drive valve device
Inventor: NOMURA SHIGEO
IPC: F02D13/06
Filed: 1999-05-26
Abstract: PROBLEM TO BE SOLVED: To make compatible the prevention of a catch error of a valve with the reduction of power consumption in an electromagnetic drive valve device. SOLUTION: In the rest cylinder (fuel injection rest cylinder) at the variable cylinder control time, the inconvenience such as an after fire is not generated even if a catch error of a valve 24 is generated. Therefore, the catch error is generated and its limit electrification condition is learned by lowering the current-carrying amount of close/open side coils 33, 35 gradually while repeating the opening/closing of the valve 24 of the rest cylinder. After learning, the current-carrying amount of the closing/opening side coils 33, 35 is controlled based on the learned value.  Thus, even if the limit electrification condition, in which the catch error is generated by the oil viscosity, the change of the internal pressure of the cylinder and the aging effect of parts, is changed, the current-carrying amount of the closing/opening side coils 33, 35 can be controlled to the necessary minimum current-carrying amount by which the catch error is not generated, responding to the change of the limit electrification condition.

Thus, the effect of phase difference caused between 1st and 2nd detection outputs obtained from 1st and 2nd photodetectors is eliminated and fed to the read information signal forming section or the phase difference caused between the 1st and 2nd detection outputs obtained from the 1st and 2nd photodetectors is neglected substantially. Thus, both the 1st and 2nd output signals are not passed through the phase shift section 34 but fed to the read information signal forming section. Thus, the excellent S/N is obtained.

Abstract: PROBLEM TO BE SOLVED: To easily align a transfer roller, a pressure roller and a transfer roller, and to soften a shock generated when the rollers come into contact with each other by providing a driving means for moving forward and backward the transfer roller which is selectively brought into contact with and separated from a backup roller and the pressure roller. SOLUTION: At the time of printing, a transfer roller 103 moves forward between a backup roller 113 and a pressure roller 102. That is, when a rotary disc 135 is turned at a designated angle by a motor, a crankshaft 133 makes a circular motion, so that a support table 123 advances. Accordingly, the transfer roller 103 advances between the backup roller 113 and the pressure roller 102 to come into contact with the rollers. At this time, it is desirable to suitably control the pressing force of the transfer roller 103 in such a manner that the repulsive force between the pressure roller 102 and the transfer roller 103 is equal to the repulsive force between the transfer roller 103 and the backup roller 113.

Abstract: PURPOSE:To enable to supply a current having the period where a coil current will be brought to zero without imparing low power property by a method wherein a resistor is connected to the end part of a coil and the other end of the resistor is earthed through the intermediary of a switching element. CONSTITUTION:In the coil driving circuit which is used for generation of rotary magnetic field on a magnetic valve memory device, when the voltage drop generating by a resistor 7 when coil current is reduced, the coil current runs to an earthing terminal via the resistor 7 and a Q56. At this time, the charging of electric charge of a Q2 is discharged through the resistor 7 and the Q56. Accordingly, at the point of time when the coil current is turned to zero, the parasitic output capacity of Q2 and Q4 is not charged, and Q1 and Q3 are placed under the condition wherein electricity is charged in unipolarity, i.e., source is in positive and drain is in negative polarity. In this case, the electromotive voltage of the closed circuit formed by the parasitic output capacitor and a coil 5 is turned to zero by being cancelled by the charging electric charge of the parasitic output capacitory, and the electromotive voltage of the closed circuit formed by the parasitic output capacitor and the coil 5 is also turned to zero, because of the zero charging electric charge of the parasitic output capacitor. Accordingly, no resonance voltage is generated on the coil 5, thereby enabling to provide the period where current will be zeroed.
