The present invention determines whether or not a mounted tip and a dispensing amount match with each other in order to prevent contamination in a dispensing device. The present invention is provided with a pipette mechanismthat performs suction and discharge, a motorthat drives the pipette mechanism, and a pressure sensorthat detects a pressure of the pipette mechanism. A dispensing tipis mounted to the pipette mechanism. A control computercontrols the motor, drives the pipette mechanism in a suction or discharge direction, and determines a type of the dispensing tipon the basis of a difference in pressure waveform detected by the pressure sensor

Dispensing device and method

A method of disassembling a steam generator including a body portion, a water chamber, a tube plate and a plurality of heat transfer tubes, the method includes: a step of obtaining a disassembly target including the tube plate and a part of the heat transfer tubes; a step of specifying the heat transfer tube fixed to the tube plate; a step of releasing fixation between the part of the heat transfer tube and the tube plate; and a step of pulling out the part of the heat transfer tube from the through-hole, in the step of releasing the fixation, the TIG heating head is inserted from the primary region side, and in the step of releasing the fixation, the TIG heating head is moved to a plurality of streaks only in a direction from the primary region side to the secondary region side.

Method of disassembling steam generator

In a fixing device in which fixing defects can be suppressed and which can be reduced in size, and an image forming apparatus comprising the fixing device, setting is performed such that the surface temperature of an outer peripheral belt surface serving as a non-heated belt surface of a fixing belt is substantially equal at a heating region inlet at the upstream end of a heating region and a heating region outlet at the downstream end of the heating region such that the temperature difference between the surface temperature of the outer peripheral belt surface at the heating region inlet and the surface temperature of the outer peripheral belt surface at the heating region outlet is no more than 5 [&#xb0; C.].

Fixing device and image forming apparatus comprising same

A cooling device used in an electrophotographic image forming device includes a cooling roller, which is a heat roller, and a backup roller pressed against the cooling roller to form a nip portion therebetween. After being discharged from a fixing device that thermally fixes a toner image onto a recording sheet, the recording sheet passes through the nip portion, whereby the cooling roller cools the recording sheet. The cooling roller is maintained at 100&#xb0; C. or higher.

Cooling device for cooling recording sheet

In the obstruction detection apparatus incorporated in a vehicle (11), ultrasonic wave transmitter/receiver (16 to 19 171) for changing a combination of transmitting of ultrasonic waves and of receiving of reflected ultrasonic waves, a CPU (20) calculates a distance between the vehicle (11) and an obstruction and stores data corresponding to the calculated distance into the distance table (23), and the LC display device (27) displays the obstruction on display bars of a lattice shape corresponding to the data stored in the distance table (23), and a buzzer (26) sounds an alarm for a driver.
