Title: Fixing device
Inventor: TAKEHARA YOSHIFUMI
IPC: G03G15/20
Filed: 1988-11-17
Abstract: PURPOSE:To prevent the wasteful wearing of a cleaning device and a fixing roller by providing even a fixing roll on a side which is not brought into contact with an image not fixed by a transferring material with the cleaning device in such a way that the cleaning device is touchable/detachable to/from a roll surface and operating it as necessary. CONSTITUTION:A cleaning web mechanism 19 is provided on the upper part of a heating roll 11 having a heater 11a inside, and on a pressurizing roll 12 which makes a pair with the heating roll 11, the cleaning device 30 is disposed in such a way that a cleaning blade 32 is touchable/detachable to/from the roll surface. At an ordinary single-side copying time, the cleaning blade 32 is in a separated condition from the pressurizing roll 12, and at a double-sided copying time, a solenoid 33 is turned into ON by a controlling means 34. Then the cleaning blade 32 abuts on the pressurizing roll 12 against the force of a spring member 35 and a cleaning operation is performed. Since the cleaning device 30 is not constantly operated with respect to the fixing roll 12 but operated as necessary, the wasteful wearing of the cleaning device and the fixing roll 12, etc., are prevented.

Title: Comparator hysteresis circuit
Inventor: KIKUYAMA SEIICHIRO
IPC: H03K3/023
Filed: 1989-11-06
Abstract: PURPOSE:To bring an output voltage to an L level even when an input level difference is small by adding a hysteresis circuit in which the emitter of an NPN transistor(TR) is connected to the emitter of other NPN TR to a conventional comparator circuit. CONSTITUTION:A hysteresis circuit realized with simple circuit change such as connection of the emitter of an NPN TR 6 to the emitter of an NPN TR 7 is added to a conventional comparator circuit. Then the emitter of the NPN TR 6 connects to the emitter of the NPN TR 7, then the NPN TR 6 is being conducted while an input voltage 200 gets lower than a voltage 300, the voltage of a resistor 11 rises by increasing the emitter current, then positive feedback is applied and the NPN TR 7 is rapidly interrupted. Thus, the voltage gain is increased while making a common mode input voltage operated up to a ground level 400 and even when an input voltage difference (300-200) is small, the output voltage goes to an L level.

Abstract: PURPOSE:To prevent the feed irregularity of a recording sheet and to correct the curl thereof by providing a feed means for removing the slackening of the recording sheet and bending the recording sheet passing through the feed means in the direction opposite to a curl direction. CONSTITUTION:When a recording sheet 14 is fed in a recording sheet feed direction and a feed roller 23a is rotated with the feed of said sheet, an one-way clutch becomes a lock state with respect to the shaft fixed to a main body.

Title: Game machine
Inventor: NAGANO MITSUYOSHI
IPC: A63F7/02
Filed: 1999-10-13
Abstract: PROBLEM TO BE SOLVED: To prevent the situation that the interest of a player is reduced and to allow the player to play a game for a long period without getting tired by generating a second special game state in succession to a first special game state when the prescribed pattern matches with a specific pattern or when a prescribed mode is displayed on a pattern display section. SOLUTION: When a shot ball enters a pattern start port 4 to win, the pattern of a pattern display section 3 is fluctuation-displayed then stop-displayed. If this stop pattern is a big bonus pattern, a first special game state centered with the intermittent opening of a large winning port 7 occurs. If a specific big bonus pattern is further stop-displayed at this time, or if an aligned mode is displayed in a bingo game as the prescribed mode, a second special game state occurs as a short fluctuation state. The second special game state can be easily understood by a player because marks in the bingo game are gradually reported in an aligned mode in conjunction with the opening actions of the large winning port 7 during the occurrence of the first special game state.
