Title: Method for controlling track access of optical disk device
Inventor: YANAGI SHIGETOMO
IPC: G11B7/085
Filed: 1988-11-30
Abstract: PURPOSE:To prevent excessive coarse seeking and fine seeking by detecting an optical beam position from the center of an optical head, correcting a moving distance obtained from a difference between an objective track and a present track by means of the detected position. CONSTITUTION:For performing coarse seeking which is to position the optical head 2 in the objective position by a motor 6 and fine seeking which is to position the optical beam of the optical head 2 in the objective track by a servo control part 3, the position of the optical beam from the center of the optical head 2 is detected, the moving distance is calculated from the objective track, the present track and the detected position, whether to perform coarse seeking or fine seeking is decided by the moving distance and the moving quantity of coarse seeking is calculated from the moving distance. Namely, the retry of coarse seeking and excessive fine seeking can be prevented and a track access time can be shortened by detecting the position of the optical beam from the center of the optical head 2 and using the detection position for the calculation of the moving distance.

Title: Image forming device
Inventor: TSUKADA SHIGERU
IPC: H04N1/407
Filed: 1996-11-14
Abstract: PROBLEM TO BE SOLVED: To keep an image forming device in a state where the consumption of toner and the fluctuation of an image density are free from problems and to minimize the decrease of productivity in copying for a customer, even if it is necessary that the formation of an image is temporarily interrupted and a dummy cycle for forming a reference patch is executed. SOLUTION: In the case copying is unfinished in a mode requiring the dummy cycle and the number of image forming times CNT from the formation of the reference patch at the previous time becomes >=20 (YES in 192), only when the remaining number of consecutive image forming times at the this time exceeds five (YES in 194), the dummy cycle is executed to form the reference patch (196). In other words, when the remaining number is five or less (NO in 194), the formation of the reference patch is inhibited because the stability of the density of a copied image does not have any problem, even if the formation of the reference patch and the control of the image density are not attained up to the completion of copying.

The temperature of the catalyst layer 7 is sufficiently raised and the premixture gas generates catalyst combustion mainly on the surface on the upstream side (front face) and flows through a honeycomb-shaped through-holes 7a to the downstream side. At the same time, the premixture gas tries to pass the circumferential section of the catalyst layer 7, too. Furthermore, the premixture gas that enters the circumferential section is obstructed by the projections 11 of the support frame body that is provided to fit in the groove of the catalyst layer 7. Further, the premixture gas that tries to pass the circumferential section of the projections 11 is subjected to oxidation reaction in the side groove of the catalyst layer 7.
