Title: Thermal fuse
Inventor: OTA NAOKI
IPC: H01H37/76
Filed: 1999-02-10
Abstract: PROBLEM TO BE SOLVED: To surely detect abnormalities when a metallic wire melts and enhance winding with a simple structure by inserting a core wire wound with the metallic wire melted at a predetermined temperature laterally on a core material made by twisting one or a plurality of core materials at a predetermined pitch into a protective tube. SOLUTION: In a core having a structure of a core material 1 wound with a metallic wire 2 laterally, the valley parts of a twist form spaces among the protective tube inner side, the core material 1 and the metallic wire 2. Thereby, when the metallic wire 2 is melted, molten mater flows into the spaces and the fusing of the metallic wire 2 can be detected surely. Spaces are also formed between a core wire and the protective tube so that the fusing of the metallic wire 2 can be detected further surely. As for the metallic wire 2, it can be selected from wires melted at a predetermined temperature required but a solder wire is used because of easy availability and costs, etc. As for the protective tube, a tube of a braised sleeve 3 coated with a silicone rubber is used.

Title: Image forming apparatus
Inventor: FURUKAWA SATOSHI
IPC: B41J2/385
Filed: 1993-02-23
Abstract: PURPOSE:To provide an image forming apparatus that can form an image with high quality at high velocity. CONSTITUTION:The aperture electrode 1 of an image forming apparatus is of the type in which a plurality of apertures 6 having a diameter of 100mum is formed in a row on a polyimide insulation sheet 2 having a thickness of 25mum, and on the opening periphery of each aperture in the upper surface side of the insulation sheet 2, a control electrode 4 is formed with a thickness of 1mum. The control electrode 4 is formed only on the down stream side in the direction of movement of a toner carrier roller from the center of the apertures 6, and it is not disposed on the upper stream side thereof. Accordingly, toner carried on the toner carrier roller does not adhere to the surface at the side of the toner carrier roller of an aperture electrode 1, with result that a large amount of toner is supplied below the apertures 6 of the aperture electrode 1, so that an image with high density can be formed on the carrier.

IPC: B62H1/02
Filed: 1990-02-16
Abstract: PURPOSE:To provide possibility of putting a motorcycle stand at a standstill in the accommodated state without causing damage to the shock absorber mounting part, suppress the costs and reduce the weight by furnishing a stopper at the rear shock absorber mounting part of a swing arm, and allowing the center stand in accommodated state to be in contact with the stopper. CONSTITUTION:When a center stand 41 is put in the accommodated state from upright attitude, its stopper cushion 52 comes in contact with the bottom 54 of a plate 53 to mitigate shock, and the stand 41 comes to a standstill. A mounting boss 36 of this plate 53 is the mounting part of the rear shock absorber 53 where a strong shock load acts on, and is secured fast to a swing arm 26 to provide high rigidity. When the stand 41 is returned from upright to accommodated state, therefore, there is no risk of damaging the plate 53, mounting bass 36, etc. even though an impact force is applied to the bottom of the plate 53 by the cushion 52. To permit the bottom 54 of the plate 53 to function as the stopper for the cushion 52, it is enough to extend the plate 53 a little downward, which allows achieving the device in light weight.

IPC: H04N7/081
Filed: 1986-02-18
Abstract: PURPOSE:To eliminate the need to increase the number of memories and to shorten a wait time by storing data on programs which are not reserved in order in program memories where data on a reserved program is not stored among plural programs memories. CONSTITUTION:Program data are stored in program data areas of respective reversed programs areas of reservation memories 31-3n respectively. A CPU judges whether programs data inputted to a work memory RAM is a reserved program or not and when so, the CPU stores program data in the reservation memories 31-3n and sets a flag indicating that a reservation is made. When the data is not the reserved program, it is further judged whether or not there is a vacant reservation memory, and when there is the vacant reservation memory, unreserved program data are stored in free reserved program areas of the reservation memories in the order of transmission. Therefore, when a viewer selects a program, the reserved program is displayed speedily and the wait time is reduced as much as possible even when the program is not reserved, thus displaying the program.

Filed: 1990-02-15
Abstract: PURPOSE:To improve reliability by generating an alarm signal, being delayed by the time which is set according to the load current value of an AC/DC converting means, after detecting interruption of an AC power supply. CONSTITUTION:When the power stoppage detecting signal based on the break of an AC power supply is input to a transistor TR1 through a resistor R1, the transistor TR1 becomes conductive, and the charge voltage of a capacitor C is discharged through a resistor R2 and the transistor TR1. When the voltage VC of the capacitor C by this discharge has dropped to the level of the threshold voltage VS of a comparator 22, the comparator 22 outputs an ON/OFF inverting signal, and this signal is input to the transistor TR3 through a resistor R10, and is amplified, and then it is output as the ON/OFF signal at the specified level from a reset terminal 19. At this time, when a load current I is large, the delay time before outputting a reset signal 19 is short, whereas when the load current I is small, the delay time becomes long.

Abstract: PURPOSE:To facilitate the exclusive control of access by allowing the access to a shared file only when the use of lock file is permitted. CONSTITUTION:A program A maintains a lock file R in a read mode for the time t0-t1, reads/writes files 1-n, and rewrites the lock file at the time t1 after the final file is updated. During that period, a program B will not receive any read request even if it is issued to any of the files 1-n, maintaining them in a read request wait state. At the time t2 after the program A releases the lock file R, the program B reads the lock file R immediately. Then the program B starts updating the files, reading/writing the file, then file 1, then file 2 and so on. During this period t2-t3, the program A will be waiting for a read request even if a file read request is issued.
