Patent JP-H10232002-A (JP)
Title: Boiler
Inventor: MATSUDA JUNICHIRO
IPC: F22D1/02
Filed: 1997-12-17
Abstract: PROBLEM TO BE SOLVED: To provide a boiler unit which restrains an increase in the heat transfer area of a reheater and improves the control response, when arranging the total number of reheaters on the rear heat transfer part in which the quantity of gas distribution is controlled by a means that controls the flow rate of gas distribution such as a gas distributing damper. SOLUTION: This boiler controls a gas flow rate by providing a gas passageway leading to the inlet of a rear heat transfer part with only pendant superheaters 50 and 60, the rear heat transfer part with a horizontal reheater 71, and the outlet side of the divided gas passage of the rear heat transfer part with each damper 90. The heat transfer area of the superheaters 50 and 60 are set to have the exhaust gas temperature at the inlet of the rear heat transfer part of 1,000 deg.C-1,100 deg.C at the maximum load of the boiler, so that the increase in both the heat transfer area of the reheater 71 and the heat capacity can be restrained due to the rise in the temperature of gas and steam which flows inside the reheater 71. Approximately 1,100 deg.C is the minimum temperature at which coal ash starts to soften, and this is cooled down to be solidified, thus preventing the slacking of the reheater 71.

Title: Temperature control method of thermal head
Inventor: KOJIMA TETSUYA
IPC: B41J2/365
Filed: 1996-12-27
Abstract: PROBLEM TO BE SOLVED: To eliminate the abrupt fluctuation of the environmental temperature of the neighborhood of a thermal head before and after the start of recording by a method wherein cooling fans for supplying cooling air to the thermal head are continuously or intermittently driven not only during recording but also except during recording. SOLUTION: A cooling controlling device 86 continuously drives cooling fans 76 at recording and, at a standby, drives the cooling fans 76 similarly as at recording or by a driving method other than that at the recording. Accordingly, the temperature in the neighborhood of a thermal head 66 is kept at a temperature nearly equal to that of the outside air. As a result, the change of the environmental temperature of the thermal head 66, which is too sudden for a thermistor 74 to follow up, can be prevented from occurring, resulting in realizing the detection of a precise temperature by the thermistor 74.  As a result, by assuming the temperature of the cooling air at recording as being nearly equal to the temperature of the air in the neighborhood of the thermal head measured before recording, the error in the density correction can be reduced, resulting in allowing to reduce the error in the density correction or the like.

Title: Cooling air valve for vacuum cleaner
Inventor: SUZUKI MASAKI
IPC: A47L9/10
Filed: 1991-12-13
Abstract: PURPOSE:To prevent the generation of noises without vibration of a valve being opened half by a method wherein a valve closed separates from a valve sheet the moment the valve begins to open receiving a load of air and a valve port is set to open. CONSTITUTION:A valve 17 has a circular permanent magnet 20 which is fixed concentrically on a magnetic body 19 and a magnetic body 19 with a T-shaped section inside and a circular magnetic body 21 is provided on the outside surface of a cap 12. The valve 17 is energized in the direction of closing a valve port 13 by a spring resilience of a spring 18 and a magnetic force of the permanent magnet 20 and the magnetic body 21. The valve 17 will not separate from a valve 14 and is kept from vibrating at an early stage even when a filter 3 is clogged during the use of an electric cleaner 1 to let a negative pressure advance in a suction chamber. As an internal pressure of the suction chamber 5 lowers until it overcomes a combined load, the valve 17 retracts to make the valve port 13 open. Here, an energization load F1 increases proportionally but a magnetic force between the permanent magnet 20 and the magnetic body 21 decreases in inverse proportion to the square of the distance between the both thereby allowing the retraction of the valve 17 sufficiently.

SOLUTION: An energizing sheet 21 is laid on a guide rail 9 along its longitudinal direction, and the other end of a first lead wire 22, one end thereof being connected to a safety switch 4, is slid into contact with the energizing sheet 21. In addition, the other end of a second lead wire 23, one end thereof being connected to the energizing sheet 21, is connected to a tool box 21 on a car. In a car door safety device thus constructed, since the necessity of wiring chain conventionally used for protecting the lead wire following the opening/closing operation of a car door 1 is eliminated, the damaging of the apparatus caused by the interference of the chain is prevented, and the time of laying the lead wire is shortened.
