Title: Drying furnace for coating and method of drying object to be coated
Inventor: KAZAMA SHIGENORI
IPC: B05D3/02
Filed: 1995-10-06
Abstract: PROBLEM TO BE SOLVED: To shorten the time required for hardening a coating film by inserting an infrared ray transmitting insulating material between an infrared ray radiation source and an object to be coated in a radiation heating zone. SOLUTION: A drying furnace for coating 100 is formed into a chevron furnace and is provided with a radiation heating zone 1 on the inlet side. In the radiation heating zone 1, an infrared transmitting insulating plate 30 is inserted between a heat radiating duct 20 into which a high temperature hot air is introduced to generate far infrared rays and a body W. The infrared transmitting insulating plate 30 is constituted of a material such as quartz glass or ceramic glass which transmits infrared rays IR and also excellent in heat insulating property. On the outlet side of the drying furnace for coating 10, a convection heating zone 2 in which a hot wind W is blown out to heat the body W having passed through the radiation heating zone 1 is installed.  In this way, energy of the infrared rays IR of a radiation source is increased to raise the temperature rise speed in the radiation heating zone 1, thus attaining the shortening of initial heating time.

Abstract: PROBLEM TO BE SOLVED: To precisely absorb and purify NOx calculating a NOx adsorption amount absorbed in a NOx absorbing and storage type catalyst, and converting an air-fuel ratio of mixture supplied to an engine into a prescribed rich air-fuel ratio at the time of exceeding a judging value in which an accelerating condition is set according to the calculated NOx adsorption amount. SOLUTION: When an operation is carried out with a rich air-fuel ratio having a stoichiometric air-fuel ratio or more, absorbed NOx is released, and a NOx absorbing and storage type catalyst 15 arranged in an exhaust passage 12 is reduced by an operation of HC, CO in exhaust gas. In this case, air-fuel ratio sensors 16, 17 are arranged on an upstream side and a downstream side of the catalyst 15 in the exhaust passage 12, a catalyst temperature sensor 18 is arranged on the catalyst 15, and those outputs are inputted into an ECM 20. When it is detected that the present catalyst 15 is in an accelerating condition such that NOx is not absorbed sufficiently, an air-fuel ratio of mixture supplied to an engine is converted into a prescribed rich air-fuel ratio. It is thus possible to recover an absorbed efficiency of NOx in the catalyst 15 as well as releasing and purifying NOx.

Filed: 1989-11-02
Abstract: PURPOSE:To effectively remove a noise while preserving the outline of a character area by changing the characteristic of a filter for the case the character area is filtering-processed and the case a non-character area is filtering- processed. CONSTITUTION:An area deciding part 1 obtains the difference (maximum luminance difference) of the maximum value and the minimum value of a luminance signal among picture signals in a block, and compares this result with a threshold S determined beforehand. Then, the block whose maximum luminance difference is below the threshold S is decided to be the non-character area, and the block over the threshold S is decided to be the character area. When the area deciding part 1 decides the block to be the non-character area, it connects the contacts of switches 5, 6 so that the picture signal read out of a buffer memory 2 is processed by a first low pass filter 3 and is outputted. When it decides the block to be the character area, it connects the contacts so that the picture signal is processed by a second low pass filter 4 and is outputted.

CONSTITUTION:At the time of performing development by applying a rectangular pulse electric field of a variable duty ratio as developing bias between an electrostatic latent image carrier 1 and a developer carrier 5 opposedly provided through a minute gap, each positive-negative polarity rectangular waveform of the pulse electric field is made independently variable to make the duty ratio variable. Fixing is made with VPP=2KV, each positive-negative peak value Va=1.0KV, Vb=1.0KV, and frequency 500Hz, for instance. With the positive-negative electrode pulse width (a) and (b) as a pair, change is performed to obtain a+b=T. The Va element and Vb element of the duty ratio are thereby made a/T, b/T respectively, and the effective direct current element volatge of the bias is made ava+bVb/T. Acccordingly, direct current power is not required as developing bias supply, and the direct element can be controlled effectively. This results in improving image graduation reproducibility and controllability.
