Title: Three-dimensional information recording medium, method for three-dimensionally recording information with the same and device therefor
Inventor: MIYAMOTO JIICHI
IPC: G11B11/105
Filed: 1993-09-16
Abstract: PURPOSE:To three-dimensionally arrange recorded information in a medium, to enable high density recording and to considerably increase the extent of recording by imparting function to magnetically separate and couple a recording layer and a storage layer to a disconnecting layer. CONSTITUTION:In a downward transfer region, each storage layer 7 is formed by laminating a rare earth metal (RE)-rich perpendicularly magnetized layer 3 having an RE-rich compsn., a transition metal(TM)-rich intrasurface- magnetized layer 4 having a TM-rich compsn., a TM-rich perpendicularly magnetized layer 5 and an RE-rich intra-surface-magnetized layer 6 in order from the top and such storage layers 7 are laminated. In an upward transfer region, such layers 2-6 are laminated in the reverse order. When 100 storage layers 7 are formed, 100 times as much information as the conventional information can be stored in one meidum. Since >=1,000 storage layers 7 can be laminated in the case of a disk having the same thickness (1.2mm) as the conventional disk, >=1,000 times as much information as the conventional information can be recorded.

Title: Fixing device
Inventor: MORIGAMI YUSUKE
IPC: G03G15/20
Filed: 1996-08-30
Abstract: PROBLEM TO BE SOLVED: To improve cleaning performance and to conserve energy by allowing a fixing sleeve to have temperature distribution in the circumferential direction thereof and arranging a cleaning roller at the almost highest temperature part of the fixing sleeve other than a nip part. SOLUTION: Magnetic flux density on a circumferential surface becomes maximum at points P and R on the fixing sleeve 2, on the contrary, it becomes minimum at points Q and S. Since induction current density shows the same tendency, the generated heat of the sleeve 2 is not uniform on the circumferential surface, and parts 16a and 16b surrounded by an alternate long and short dash line locally generate heat. Therefore, on the sleeve 2, the nip part N1 and an area N2 opposed to the nip part N1 generate the heat more than a middle point between them. The generated heat of the nip part N1 shows fixing temperature T1, and that of the area N2 opposed to the nip part N1 shows temperature T2 which is lower than the fixing temperature N1 but at which toner is melted. Then, the cleaning roller is arranged in this area where the temperature is equal to or above the toner melting temperature T2.

Title: Protective circuit against instantaneous service interruption
Inventor: IMAHASHI HISASHI
IPC: G05F1/10
Filed: 1985-10-16
Abstract: PURPOSE:To make the capacity of a capacitor for smoothing smaller so as to economize the mounting space of the titled circuit, by providing a driver driving circuit which detects a momentary voltage drop or momentary voltage stop earlier than the reset signal of a microcomputer. CONSTITUTION:When a momentary voltage drop or momentary voltage stop takes place, a smoothing voltage Vun starts to drop and reaches a level, at which to electric current is made to flow to the constant-voltage diode 101 of a driver driving circuit 10. At this time, the transistor 104 of the driver driving circuit 10 is turned off and no electric current is supplied to a driver 8. Therefore, the dropping time of the smoothing voltage Vun suddenly becomes slow since then and, as a result, it takes a long time until the reset signal of a reset signal circuit is inverted. Since the electric current consumed by the driver 8 is eliminated when a momentary voltage drop or momentary voltage stop occurs in such a way, the smoothing capacitor of a smoothing circuit can be made smaller and, accordingly, the control substrate of a microcomputer can also be miniaturized.

Title: Optical recording disk
Inventor: YOSHIDA TOMIO
IPC: G11B7/24073
Filed: 1983-12-06
Abstract: PURPOSE:To obtain an optical recording disk which has little external disturbance to a tracking error signal and can count the number of sectional grooves precisely at the time of retrieval by connecting bits in a format area with each other by fine grooves. CONSTITUTION:A space between a bit a1 and a bit a2 in a format area of an optical recording disk is connected by a groove b1 having width thinner than those of the bits a1 and the a2. A space between the bit a2 and a groove 2 is connected with a fine groove b2. With the constitution, when light beams travel along a guide track, diffraction is generated by the groove b1 between the bits a1 and a2, a tracking error signal is produced, and a large external disturbance will not occur. When the light beams travel between the bits a1 and a2 in an arrow X direction, and pass through between them at the time of retrieval, diffraction is generated by the groove b1, and a signal crossing the groove is produced, thereby making accurate retrieval possible. A width W1 of the bit part and a width W3 of the groove have almost the same value, and a width w2 of the connecting groove is preferably >=1/2 of the width w1 and w3.

Title: Charge input circuit

IPC: H01L21/339
Filed: 1987-09-14
Abstract: PURPOSE:To improve the injection efficiency by a method wherein a source potential is fed back to a substrate potential of a PV device. CONSTITUTION:An output voltage of a voltage source 6 obtained by an input by positively feeding back a source potential Vs of an FET 2a to a substrate potential of a PV device 1 is AVs if the gain of an impedance conversion circuit 5 is designated as A. In addition, formulas I0=I1+I2, Vs=I2/gm and Vs=R0.I1+ A.Vs become valid, and a relationship between 12 and 10 is obtained. A is 1 or less; e.g., if A=1, then I2=I0.I1=0 and the maximum injection efficiency is obtained. If the source potential Vs of the transistor 2a is fed back to the substrate potential of the PV device 1, an operation point is changed in accordance with an input photoelectric current I0 and an operation at a fixed operating point becomes possible. Then, the feedback gain in a high-frequency region is lowered by using a low-pass filter 7; by this operation, the injection efficiency of a high-frequency component is lowered; an S/N ratio is improved. That is to say, an efficient injection operation is executed even against a self-noise as a dominant noise of the ideal PV device 1.

Title: Piston pump
Inventor: MIDORIKAWA MITSUI
IPC: F04B11/00
Filed: 1991-09-10
Abstract: PURPOSE:To obtain a large flow rate with a small-sized pump and substantially equalize two maximum discharge rates to each other even when the discharge rate is lowered by cavitation at a low temperature in a pump by which at least two discharge rates are discharged dividedly by keeping a hydraulic pressure balance so as not to separate a cylinder block from a control plate, while improving suction performance and enabling high-speed operation of the pump. CONSTITUTION:Circular-arc openings having different diameters are formed on an end wall 11 of a rotationally driven cylinder block 6. A width W10 of an opening 13' of a small diameter circular arc along a normal line is larger than a width W9 of an opening 13 of a large diameter circular arc along a normal line. At the time of a maximum discharge rate of a pump, areas of openings on smaller and larger diameter sides are distributed so as to equalize suction performance of the small diameter side opening 13' to that of the large diameter side opening 13. It is thus possible to improve suction performance of the pump, operate the pump with high speed, and obtain substantially the same maximum discharge rate at every opening.

The warm-up waterway 106 and a tank circuit 107 are thereby opened, so that the whole cooling water of high temperature stored in a heat storage tank is circulated in an engine 1 so as to accelerate warm-up of the engine. Immediately after the start of the engine 1, low temperature cooling water discharged from the engine 1 is retained in the heat storage tank 4 so as to be prevented from flowing back to the engine 1. The quantity of harmful matter discharged at the time of warm-up can thereby be reduced, and fuel consumption can be improved.
