Title: Magneto-optical reproducing device
Inventor: OTSUKA YASUO
IPC: G11B11/105
Filed: 1986-05-16
Abstract: PURPOSE:To prevent the operational frequency component of a double refraction correcting means to be included in a recording signal, or a reproducing signal, to make the recording frequency of a signal into a wide band area, to prevent the lowering of an S/N, and to improve recording density, by operating the double refraction correcting means when a laser beam is projected on an area other than a recording part. CONSTITUTION:In a phase compensation circuit 100, a low-pass frequency component, such as a servo signal, etc., is eliminated from the signal outputted from an adder 22, then only a head signal of high frequency is outputted, and it is amplified by a pre-amplifier 28, and an analog signal is sliced by a regulated value of threshold level by a data slicer 29, and is waveform-arranged, and it is changed to a digital signal. A synchronizing signal detection circuit 31 detects a synchronizing signal recorded in the header signal, and also, outputs a clock pulse outputted from a clock circuit 30 fitting for the synchronizing signal. A counter 32 counts an outputted clock pulse, and performs the recording and the reproduction of a photomagnetic signal, and the output of the ON/OFF of a double refraction correcting circuit system.

Title: Automatic exposing device
Inventor: NAGATA KOICHI
IPC: G03B27/00
Filed: 1991-04-16
Abstract: PURPOSE:To provide an automatic exposing device which obtains an appropriate exposure value regardless of the size of an original. CONSTITUTION:When the original 1 passes an original size detecting sensor 4, the size of the original is detected. A photometric sensor 3 performs photometry for the original 1 fed by a feeding mechanism 5 and a feeding belt 2 at a stopping position 21. When the size of the original 1 is nearly equal to a photometric range 6, output voltage from the sensor 3 is not corrected and the exposure value is decided based on the output voltage. When the size of the original 1 largely differs from the size of the photometric range 6 as the result of comparison, the output voltage is corrected and the exposure value is decided. In order to change the photometric range of the sensor 3, a switching plate 71 is disposed between the sensor 3 and a lens 73 for a photometric sensor and switches windows 8A-8D for detection. The photometric range is changed according to the size of the windows 8A-8D. Furthermore, the switching plate arranged in parallel crosses is moved corresponding to the size of the original to vary the size of the window, and the photometric range of the sensor 3 is changed.

Title: Fixing roller
Inventor: HIBI TAKASHI
IPC: G03G15/20
Filed: 1986-05-15
Abstract: PURPOSE:To obtain a larger quantity of heat with less power consumption, by containing an oxide catalyzer in a hollow roller body and causing a catalytic exothermic reaction by supplying a mixture of an oxidizing gas and combustible gas to the catalyzer. CONSTITUTION:The oxide catalyzer 4 contained in a hollow roller body 3 is heated by a heating electric wire provided in the vicinity of a gas inlet. When a mixed gas of an oxidizing gas and combustible gas is introduced into the hollow space of the roller body 3 through the gas inlet from a mixed gas tube 7, a gaseous catalytic exothermic reaction actively takes place, especially, in the vicinity of the gas inlet and infrared and far-infrared rays are radiated. When the heat is transmitted to the catalyzer 4 at the central part and in the vicinity of the discharge port, the surface of the catalyzer 4 uniformly radiates infrared and far-infrared rays. The heat is transmitted to the roller body 3 and the surface of the roller body 3 reaches the temperature suitable for fusing and fixing toner. Therefore, this fixing roller of a high heat value with less power consumption can be obtained.

Title: Preventing device for flow of oil in scroll compressor
Inventor: NAKANISHI MICHIMASA
IPC: F04C29/02
Filed: 1982-06-30
Abstract: PURPOSE:To enable improved supply of oil when the compressor is started again by providing a non-return valve in the oil supply line to prevent flow of oil from the fuel supply line to the low pressure area when the compressor is stopped. CONSTITUTION:Non-return valve 8 is installed in oil supply line 6. The body of non- return valve 8 is shaped like a ball. As the valve body moves to outer side pocket section 9 from the center of the oil supply line due to cetrifugal force of the driving axis of an electric motor while the compressor is operating, oil line 7 is kept open. When compressor stops, however, said centrifugal force is lost and said valve body returns to the center of said oil supply line closing the line to prevent the flow of oil. Sufficient oil remains in an oil basin 10 assuring adequate oil supply when the compressor is restarted.

Title: Manufacture of lithium secondary battery and manufacture of winding body for lithium secondary battery and manufacture of positive electrode body for lithium secondary battery
Inventor: YAMAMOTO TAMOTSU
IPC: H01M10/0566
Filed: 1998-04-22
Abstract: PROBLEM TO BE SOLVED: To prevent an increase in the battery can volume from that at installation time by the expansion of a negative electrode at charging time, by combining a positive electrode member, coated with an active material capable of storing/releasing lithium ions, whose lithium ions are released by charging operation before being assembled with a negative electrode member capable of storing the lithium ion, with another negative electrode body capable of storing/releasing lithium ions. SOLUTION: A positive electrode member having a positive electrode mix 21 containing a positive electrode active material such as LiCoO2 becomes a lithium ion-released positive electrode body 2 by passing an electric current in a lithium elimination unit between it and a pseudo-negative electrode body such as copper nonreactive with lithium. A spiral electrode wound body 1 with a sperator 4 such as porous polyethylene between this and a negative electrode body 3 of lithium metal and an alloy capable of storing/releasing a lithium ion, is installed in a battery can to be sealed after pouring an electrolyte.  Since the positive electrode body 2 is in a charging state, the volume of the negative electrode body 3 contracts after discharge, and is restored to the former state by the expansion after recharge, so that the respective electrode bodies will not be broken by a mutual pressure so as not to reduce battery capacity.

Filed: 1983-06-23
Abstract: PURPOSE:To enable stepwise selection of image quality from high to low contrast by changing conditions for electrostatically charging a photosensitive body through changeover of switches. CONSTITUTION:A photosensitive layer 2 is formed on a grounded conductive substrate 3 to obtain a photosensitive body 1. Corotron wires 4, 4' kept negative with a power supply 6 are surrounded with a corotron shield 5. The corotron charger uniformly charges the layer 2 by normally grounding the shield 5.

IPC: B65H5/06
Filed: 1990-04-27
Abstract: PURPOSE:To freely change the advancing direction of a sheet in a small space by providing a control means to control transport of the sheet and change of the advancing direction through controlling a first and a second driving means. CONSTITUTION:When a sheet S is inserted between a driving roller 1 and a driven roller 2 in the Y direction, the sheet S is pinchedly held between the two rollers and transported in the Y direction by the driving force of the driving roller 1. When the extreme end of the sheet S is a little transported and reached to a desired position, a lever driving motor 14 is begun to rotate, and a lever 3 is driven to rotate in the G direction. Simultaneously, a roller driving motor 11 is changed in speed so as to conform the rotating angular speed of a gear 7 with the rotating angular speed of the lever 3. Consequently, the driving roller 1 is in the relative stop condition against the lever 3, and the advancing direction of the sheet S is changed in the condition in which the distance from the contact point of the driving roller 1 to the extreme end of the sheet S is not changed.
