Title: Belt type fixing device
Inventor: NAKAMURA TERUO
IPC: G03G15/20
Filed: 1997-09-17
Abstract: PROBLEM TO BE SOLVED: To make the capacity of a heat source small and to shorten the heat-up time by carrying a belt at a speed for making a specific number of rotations of the belt, during the time from the start, of the heating up of the fixing belt before printing is started, to the completion of the heat-up. SOLUTION: When all of the fixing belt 101, a heating roller 103 and a fixing roller 106 have non-stationary electric heat for heating up the surface of the fixing belt 101 from a room temp. to a temp. required for fixing, heating conditions are different by the difference between the moving speeds of the heating roller 103 and the fixing belt 101. When the moving speed of the belt 101 is very slow, the time for one rotation of the belt 1 is longer, so that the heath-up time depends on the time for one rotation of the belt 1. When only four rotations or below of the belt 101 are made until the heating up is completed, the influence of the overshooting of heating by the heating roller 103 is great. In such a case, for heating up for a higher accurate temp., as the number of the rotations of the belt 101, five rotations or more are made.

Title: Driving circuit for sense amplifier
Inventor: ATSUMO TAKAO
IPC: G11C11/419
Filed: 1992-09-22
Abstract: PURPOSE:To enable a transistor to be operated in a saturation region and to easily perform optimum design of a sense amplifier by making an output of a driving circuit as an input of a gate of a transistor for limiting current of a sense amplifier. CONSTITUTION:A p-type, MISFET-P11 and a n-type MISFET-N11 constitute a complementary inverter. Also, p-type MISFET-P10 and a n-type MISFET-N10 are an intermediate potential generating circuit, and constitute a complementary inverter. In this case, when an input signal is L level, the N11 is turned off and the P11 is turned on. Then, when resistance of the P11, P10 and N10 in an ON state are respectively made R11, RP10, RN10, output potential can be made an intermediate potential decided by RN10/(RP11+RP10+RN10)XVcc. Thereby, in a transistor CS for limiting current of a current Miller type sense amplifier, when input signals of driving circuit of all stages are H level, a gate of the transistor CS is not operated at a L level, but when an input signal is a L level, the gate is made an intermediate potential.

Title: Fixed restoring force spring unit with damper
Inventor: SUGANO HIDENORI
IPC: B66D3/18
Filed: 1989-09-29
Abstract: PURPOSE:To absorb a shock, when an object collides against a unit, by providing a one-way clutch provided damper mechanism for giving braking force to the second rewinding drum between the second rewinding drum and its supporting shaft. CONSTITUTION:When a fixed load is given to a wire 9 drawn out by a suitable length, the wire 9 is left as drawn out. On the other hand, when this load is released, a fixed restoring force spring 2 is wound back by its own resetting force to the first rewinding drum 3, and following this action, also the wire 9 is rewound to a wire rewinding drum 7 to pull an object, mounted to a terminal of the wire 9, to a fixed restoring force spring unit 1. Here a one-way clutch-provided damper mechanism acts to give braking force to the second rewinding drum 5 with restoring force of the spring 2 suppressed, and a shock of the object, when it collides against the spring unit 1, is absorbed. In addition, by providing a one-way clutch built in the damper mechanism, no damper resistance acts when the wire 9 is drawn out.

Title: Information recorder
Inventor: YOKOTA MASAFUMI
IPC: G11B19/04
Filed: 1989-09-29
Abstract: PURPOSE:To surely detect all double recording states and to prevent information which is already recorded from being destroyed by detecting the level of reflected light of a recording beam which is reflected by an optical recording medium, and also detecting whether or not there is a recorded pit between a recording light beam and a recording light beam at the same time. CONSTITUTION:The device is provided with a 1st detecting means 27 which detects the reflected light of the recording light beam from the optical recording medium 11 being lower than a specific level and a 2nd detecting means 26 which detects the recorded pit recorded yet with the reflected light of the recording light beam from the optical recording medium 11. Further, the device is provided with a stop control means 33 which stops the emission of the recording light beam by a light output means 6 with a control signal S3 based upon the detection result of the 1st or 2nd detecting means during recording and sends the control signal S3 to a control part 13 for controlling the whole device. Then the optical recording medium 11 decreases in the light reflection rate of its information recording part when information is recorded. Consequently, accidental double recording is surely detected during recording to prevent the information which is already recorded from being destroyed.

Title: Seatbelt
Inventor: HAYASHI SANKAKU
IPC: B60R22/12
Filed: 1985-11-11
Abstract: PURPOSE:To obtain a safe and comfortable seatbelt by connecting a flexible string connected to the opposite ends of a belt to a piston shaft movable freely up and down. CONSTITUTION:A piston 3 is fixed movably up and down to a cylinder 1 secured to the body side and a piston shaft 4 is arranged. Said piston shaft 4 is connected with a flexible string 11 connected to the opposite ends of a belt 7. Since slight motion of a person 13 applied with a seatbelt will never cause tension of the belt 7 because of expansion/contraction of the flexible string 11 and up/down motion of the piston shaft 4, it will never cause discomfort onto the person applied with the seatbelt 13. In case of a collision, the air in the cylinder 1 will provide shock-absorbing function responsive to the strength of impact, thereby it will never cause pain onto the person 13.

Title: Data exchange system
Inventor: CHIGA AKIHIRO
IPC: H04Q11/04
Filed: 1993-10-08
Abstract: PURPOSE:To secure the transmission path of control information and to guarantee appropriate data exchange by switching one data transmission path for control information when transmission abnormality is detected in control information transmitted by time division multiplex. CONSTITUTION:Transmission abnormality monitor means 21 and 61 monitor transmission abnormality through the transmission path 8-11. When abnormality is detected, transmission path switching means 22 and 62 switch one of the transmission paths 8-12 to 8-1n used for data transmission to the transmission/ reception path of control information. After switching, it is detected whether transmission by the switched transmission path is normal or not. When it is not normal, switching is furthermore executed. When the transmission path where transmission is not executed owing to a fault exists, restoration detection means 23 and 63 detect whether transmission is normally executed or not by a frame synchronous word. When it is normally executed, the means 21 and 61 operate so that they return the purpose of the transmission path to an original one.

Title: Dial pulse sending circuit
Inventor: NAKANO YOSHIHARU
IPC: H04Q1/32
Filed: 1988-10-07
Abstract: PURPOSE:To obviate an induction coil, and to miniaturize a dial pulse sending circuit, and to reduce the distortion of a dial pulse by constituting DC loops during sending the dial pulse and during a talk of a transistor(TR), a resistor and a capacitor as the main constituents. CONSTITUTION:At the time of the talk, since a first switch 11 is turned ON, a base current IB is supplied to the TR 13 through the resistor 15. Thus, the TR 13 is turned ON, and a loop current IL flows in a subscribers line 1. On the other hand, a second switch 12 during the talk is ON, and even when a voice signal is superposed on the subscriber's line 1, an AC current to flow in the resistor 15 is bypassed through the second switch and the capacitor 16. Therefore, an interval between the collector and the emitter of the TR 13 becomes of high impedance for the voice signal. Besides, while the dial pulse is sent, since the second switch is OFF, and the capacitor 15 is opened, the dial pulse free from the distortion can be sent.

Title: Unit for compressed gas insulated transmission line
Inventor: FUTAJIMA HIDEAKI
IPC: H01B9/06
Filed: 1998-08-03
Abstract: PROBLEM TO BE SOLVED: To provide a unit capable of being reduced in diameter and easily absorbing thermal expansion and contraction of a conductor. SOLUTION: This unit includes a sheath pipe 1 and a conductor enclosed in the sheath pipe 1, the conductor having a conductor pipe 2 and a stranded conductor 3 enclosed in the conductor pipe 2. A connecting terminal is provided at each end of the conductor. The connecting terminal is preferably a terminal board 8 pressed against the stranded conductor 3. Since the stranded conductor 3 needs only to be drawn into the conductor pipe in advance by unit length and does not need to secure a large gap to the conductor pipe 2, the outside diameter of the conductor pipe 2 can be reduced and the outside diameter of the sheath pipe 1 can also be reduced. The amounts of thermal expansion and contraction can easily be absorbed by meandering the stranded conductor 3.
