Abstract: PURPOSE:To provide a paper jam detection circuit which can stop automatically a motor in a case in which a document has been jammed between rollers driven in rotation by means of the motor. CONSTITUTION:At a document sending out device such as an image scanner, a fax machine, the drive output signal 102 of a motor drive circuit 110 and a predetermined threshold signal 104 from a threshold generating circuit 113 are compared with each other by means of a comparator 112, and in the case of the drive output signal 102 being larger than the threshold signal 104, it is decided that the motor is in a paper jam under the condition of overload, and the control of the motor drive circuit 110 is made so as to stop the rotation of the motor 111. Accordingly, the damage of a document owing to paper jam caused by the document having been jammed can be prevented effectively.

Title: Coin packing machine
Inventor: CHITOKU HIDESHI
IPC: G07D9/00
Filed: 1988-09-09
Abstract: PURPOSE:To reduce the load applied to a conveyor belt and at the same time to prevent the working defect of the conveyor belt due to jamming of coins by using a 1st horizontal conveyor belt and a 2nd tilted conveyor belt having a lock part to a conveyor device. CONSTITUTION:A conveyor device M consists of a horizontal (1st) conveyor belt 30 and a tilted (2nd) conveyor belt 31. The coins received from a lower hopper 3 and put on the belt 30 are carried horizontally to the belt 31. These coins are locked by a lock part 31A of the belt 31 and carried upward to a rotary board 4. In this case, the coins are collected by the belt 30 at the joint area between both belts 30 and 31 and carried upward after they are locked by the part 31A. As a result, the coins can be drawn up by a small amount and at the same time coin pressing force applied toward the belt 31 from the belt 30 can be reduced owing to the smooth surface of the belt 30. Thus it is possible to reduce the load applied to both conveyor belts and at the same time to prevent the working defects of the belts due to jamming of coins.

Title: Thermal head drive circuit
Inventor: ITO MASAHITO
IPC: B41J2/365
Filed: 1989-09-01
Abstract: PURPOSE:To make it possible to record data with high print quality over an extensive temperature range by controlling the supply of power to a thermal head and maintaining the temperature of the head within a specified temperature range, if a detected temperature is below a specified level. CONSTITUTION:When a reference temperature Tn at which standard recording is possible is lower than or equal to a detected temperature T, the temperature of a thermal head 14 is high and a standard recording density is obtained, if power is supplied to the head as it is. Thus, temperature sampling is continued. In the meantime, if T<=Tn, time tn is set at a register (t). Next, power is supplied to the thermal head 14 based on the time set at the register (t). As a result, the energization time of the head 14 is determined based on the temperature of the thermal head 14 in the standby mode. If an ambient temperature is low, and the temperature of the thermal head is low, the head 14 is energized for a long time. However, if the temperature of the thermal head 14 is comparatively high, the head 14 is energized for a short time. Thus it is possible to maintain the temperature of the thermal head 14 within a specified temperature range.

Filed: 1984-10-30
Abstract: PURPOSE:To improve the safety of an X-ray tube ramp by installing the second braking plate that is float-supported by a drop braking device of the X-ray tube ramp. CONSTITUTION:On a ramp 12 of an X-ray tube supporter that moves, while maintaining its balance, along a column 11 owing to a rope 16 linked to plural spring balancer equipped with springs, a freely revolvable braking plate 14 is installed with a supporting member at its center. When the rope 16 is cut away, the braking plate revolves through a spring 25 and, while tilting, bites into the column 11, thereby preventing the fall of the ramp 12. And the braking plate 14 float-supports the second braking plate 35, which bites into the column 11 in response to the slight rotating move of the braking plate 14 at the time when the rope 16 is not cut but some of the spring balancers are severed, and tension of the rope 16 changes somewhat, thereby preventing the fall of the ramp 12. Through such a second-stage braking arrangement, safety of the X-ray tube supporter can be further enhanced.

Title: Garbage treatment apparatus
Inventor: SAOTOME KANAME
IPC: F26B17/20
Filed: 1998-08-11
Abstract: PROBLEM TO BE SOLVED: To treat garbage surely to have a desired water content finally. SOLUTION: A controller 15 monitors the temperature of garbage 3 and the temperature of a treatment tank 1 by the first and second detectors 81, 82. When the temperatures reach respectively pre-determined values, since treatment is made to be finished, the temperature of the treatment tank 1 and the water content of the garbage 3 can be made to correspond to each other. Therefore, when the temperature of outside air changes, or even when the volume of the garbage 3 changes, the water content of the garbage 3 in the treatment tank 1 at the point of time of the end of treatment can be made to be a nearly desired value. Accordingly, irrespective of the variation of the temperature of outside air and the quantity of he garbage 3, the end of drying can be judged surely so that stable garbage treatment can be implemented.

Title: Position detecting device for movable member
Inventor: TANAKA YOSHIHIRO
IPC: G03B9/10
Filed: 1988-09-09
Abstract: PURPOSE:To prevent a false detection operation and to detect the correct position of a movable member by stopping a position detecting during a prescribed period immediately after the movable member has started moving. CONSTITUTION:In a shutter constitution using a bimorph Bi which counts the exposure time in response to a prescribed pulse from an opening position detection circuit, when the bimorph Bi is driven, it comes into contact with an engaging pin 12c of an opening/closing lever 12, and for an instant stress is applied to the bimorph Bi in the opposite direction. As a result voltage arises and propagates through the circuit to generate a false pulse from the opening position detection circuit PC and cause malfunction. In order to prevent this, pulse input from the opening position detection circuit is inhibited in a specified time, following which a microcomputer waits for a first opening pulse from an opening 2A to be inputted (this is inputted approximately 40msec after impressing voltage to the bimorph Bi). Thus false detection is prevented and the position of the movable member can be detected correctly.
