Inventor: HAYATA TOMOAKI
IPC: G09F3/10
Filed: 1991-06-06
Abstract: PURPOSE:To efficiently discharge air between a molding and the in-mold label and improve the quality of the molding by forming arc shaped adhesive spots which are sensitive to heat and arcuately sectioned on the rear surface of a label base material in a pattern shape. CONSTITUTION:A plate for photogravure coating is mounted on the surface of a cylinder 1. The plate on the cylinder 1 is dipped in an adhesive solution 2 and the cylinder 1 is rotated, so that dots of the plate contain the adhesive solution. Dry air 7 is blown to the plate 7 and the solid ratio of the adhesive solution 2 in the dots increases. The plate contacts the rear surface of the label base material 6 by the pressure of a pressure barrel 5 and the rotation of the cylinder 1 to transfer the adhesive solution 2 to the rear surface of the label base material 6. The adhesive 10 stuck on the rear surface of the label base material 6 is increased in the solid ratio, so the adhesive is sectioned in almost arcuately arc shape. Consequently, the adhesive dots 10 of photogravure printing are formed in the pattern shape on the reverse surface side of the label base material 6 of the in-mold label 9.

Title: Vehicle height control device
Inventor: MURATA MASAHIRO
IPC: G05B13/02
Filed: 1997-05-26
Abstract: PROBLEM TO BE SOLVED: To always realize desired controllability by completing ascent control or descent control at the lapse time point of a fixed delay time after deviation between the vehicle level on a vehicle position and target vehicle height becomes under a fixed value, and evaluating the fixed delay time based on sprung weight movement. SOLUTION: In vehicle height control, vehicle height control beginning on one wheel position is executed until a fixed delay time elapses after the vehicle height level on the wheel position enters target vehicle height width. Evaluation of this delay time is realized by the process of genetic algorithm in the step 216 as a delay time evaluating means, based on a heap quantity HH, a roll quantity HR, and a pitch quantity HP computed by the steps 210-214 as sprung weight condition detecting means. Hereby, the delay time until completing vehicle height control can be properly renewed according to the condition of a vehicle height control device, and vehicle control can be always executed without spoiling stability of sprung weight movement, regardless of individual difference of systems and aging change.

IPC: F16H9/00
Filed: 1982-08-04
Abstract: PURPOSE:To prevent lowering of the transmission efficiency and deterioration of the durability of a belt, by preventing the speed ratio from increasing or decreasing infinitely. CONSTITUTION:A maximum value -emax and a minimum value -emin of the speed ratio of a CVT are preset. At a step 59, a desired speed ratio e* is calculated from a desired revolutional speed Nin* on the input side and the actual revolutional speed Nout on the output side. At a step 60, comparison is made between e* and -emax. Here, if e* is equal to or greater than -emax, the procss proceeds to a step 70, where -emax is set at the desired speed ratio e*. Further, at a step 64, comparison is made between e* and -emin. Here, if e* is equal to or smaller than -emin, the process proceeds to a step 71 and -emin is set at the desired speed ratio e*. Resultantly, the speed ratio of the CVT is set at a value between -emin and -emax, so that it is enabled to prevent the speed ratio from increasing or decreasing infinitely.

Filed: 1986-06-11
Abstract: PURPOSE:To select plural files by using a means which reads directory information out of an external storage device for display and stores a file name selected by a pointing device. CONSTITUTION:An operator selects the files displayed on a CRT 3 by means of a mouse. File information is copied on a selection file area 8E as long as a selection file counter 8F is not equal to 0. Thus the selected file information is compared by numbers equal to the number of counters 8F. When no coincidence is obtained from said comparison, the selected file information is copied on the area 8E. While the coincident file information if obtained is deleted out of the area 8E. Furthermore, the counter 8F counts up and down by +1 and -1 when the file information is copied on the area 8E and deleted out of the area 8E respectively. Then a file operation program 8C inversely displays the file information on the CRT 3 via an IOC 8A when the corresponding file information is added to the area 8E. Then a normal display mode is reset when the file information is deleted from the area 8E.
