Title: Photorecording medium
Inventor: AOYAMA AKIRA
IPC: G11B7/24
Filed: 1985-01-24
Abstract: PURPOSE:To try a cost-down and to improve the weather resistance of the title medium by providing two or more layers of dielectric films between a photomagnetic recording layer and a transparent substrate. CONSTITUTION:The film composed of an aluminium nitride, a silicon nitride or a zinc sulfide is at first, formed on a plastic substrate or a glass substrate 8 providing a resin curable by irradiating the UV-ray on the substrate. The thickness of said film is necessary to be <=2,000Angstrom  to prevent the generation of crack. By applying said film, the reliability of the photorecording medium for long period is remarkably increased. As the plastic substrate which is not necessary to directly form a groove can be used, the large cost-down can be accomplished. And as the dielectric film may be prepared without generating the crack, the enhance effect of a kerr turning angle is effectively utilized, thereby obtaining the improvement of C/N ratio.

IPC: B42C1/12
Filed: 1994-02-03
Abstract: PURPOSE:To shorten preliminary movement time for bins as short as possible when stapling is started in a sorter provided with a stapling function. CONSTITUTION:Sort bins 12 (1) to 12 (20) store sheets fed from a sheet delivery position A while moving up or down one bit at a time. Also the stapling position B1 by a stapler 100 is just over the sheet delivery position A. Then, the sheets of odd number pages are sorted while the bins 12 move upward, and when the final sheet is stored, for example, in the bin 12 (10), the bin 12 (10) is set at the delivery position A. When the stapling is started, the bin 12 (10) is set at the stapling position B1 by moving the bin 12 (10) upward by one stage, and the bins over the bin 12 (10) are stapled in order.

IPC: F24S10/70
Filed: 1980-02-01
Abstract: PURPOSE: To improve mass production and durability, by a method wherein a powder-molded glass stem is employed to a vacuum glass tube type solar heat collecting pipe.  
     CONSTITUTION: A cylindrical metallic connector 3, piercing through a powder- molded glass stem 2, and a heat collecting metal pipe 4, being inserted into a glass tube 1 through the cylindrical metallic connector 3 and being seal-welded at the end part of the metallic connector 3, are mounted, and a heat collecting plate 5 is set at the heat collecting metal pipe 4. This permits an easy molding of the glass stem 2 which is hard to mold in case of press-molding. The metallic connector 3 pierces through the glass stem 2 and the pipe is inserted into the glass tube for seal-welding, whereby a seal-welded area between the metallic connector 3 and the glass stem 2 increases, and as a result a mechanical strength increases and durability is improved.

Title: Picking up method for motor
Inventor: YAMADA TETSUO
IPC: B32B15/08
Filed: 1986-01-22
Abstract: PURPOSE:To suppress a rush current of a motor by detecting the residual voltage to detect the rotational speed of the motor, and energizing in advance a transformer to smoothly pick up the motor. CONSTITUTION:A residual voltage VH is input through a zero-cross comparator 31 to the frequency measuring unit 32a of a calculation processor 32 to measure a frequency from the rotational speed of a motor 24. When the rotational speed of the motor 24 becomes equal to the control frequency of an inverter 21, the output voltage VM of an inverter is raised by cushion. The output voltage VM is raised by the cushion to prevent a rush current from flowing in an output transformer 22. When the voltage VM and the voltage VN become equal, a switch 23 is closed. Thereafter, the inverter 21 is controlled to control the motor 24 to the set value at a frequency setter 1.

Title: Solenoid driving device
Inventor: MATSUYAMA KOUZOU
IPC: H01F7/18
Filed: 1982-01-29
Abstract: PURPOSE:To make a titled device adequate for a driving means of a cleaning blade of an image former by driving an actuating member with a latching solenoid and moving the latching solenoid forcibly when an electric power source is interrupted. CONSTITUTION:As far as a latching solenoid 79 is latched in either of stable positions, the state thereof does not change even if an electric power source is interrupted. A solenoid 79 makes attraction or reverse action thereof when its set coil or reset coil is energized only for the time required for its plunger 79b to move but while the coils are de-energized, the solenoid holds the plunger 79b static in either of the stable positions. Thus, when a switch is interrupted or a fuse is blown while the plunger 79b is in the stable position where the same is held attracted, a blade 71 is kept in the press contact with a photoreceptor 61. In this state, the interruption of the power source is detected with a detecting means and the coil is driven forcibly to reset the plunger 79b to the reset position.

Accordingly, an arcing voltage across poles of the breaker 4 is applied to the reactance 6 of the DC circuit, and a reverse voltage applied to the thyristor becomes only a reverse voltage of the AC power source 1 at the time of steady state, thus capable of protecting the thyristor.

Abstract: PURPOSE:To prevent color development of a printing paper and fatigue of heating resistor elements from being generated, by a method wherein a voltage lower than a printing voltage is used as a voltage impressed on the heating element, when discriminating the condition of the heating element. CONSTITUTION:A central processor 26 sets the number (n) of the heating resistor elements 2-1-2-n on an appropriate register X. Then, the first stage of a shift register 6 is made to be H level by a data signal 34, and an output enable signal 36 is mad to be H level. By this, an H-level signal is supplied to the base of a transistor 4-1, and an electric current from a discriminating power source line 20 of a voltage of 5V is passed to the transistor 4-1 and the heating resistor element 2-1. However, since a transistor 12 is in a non-conductive state, an electric current from a printing power source line 14 of a voltage of 10-30V is not passed to the resistance element 2-1 or the transistor 4-1. At this moment, the voltage V28 at a junction point 28 is measured by a voltage-detecting part 30, and is compated with a predetermined upper limit value and a predetermined lower limit value. When the lower limit value <V28< the upper limit value, it is discriminated that the heating element 2-1 is in a normal condition.
