Title: Thermal transfer heat sensing recorder
Inventor: NAGANO BUNICHI
IPC: B41J2/36
Filed: 1984-05-23
Abstract: PURPOSE:To prevent the resolution from being degraded by increasing/decreasing the print area in one dot in a device possible for recording half tone. CONSTITUTION:The length (b) in the sub scanning direction of a thermal head is designed shorter than the length (a) in the main scanning direction of each heat element TH. The length l in the sub scanning direction of one scanning corresponds to the unit distance of the heat element, is sectioned by the length (a) in the main scanning direction of one heat element and an imaginary rectangular form corresponds to one dot. When M-th scanning - (M+2)-th scanning are executed, printing (21-23) is executed on a photosensitive paper sheet 2. The length in the width scanning direction of the printed part is proportional to the conductive time of a heat current Ir of the heat element TH1. Thus, the area of the printed part in the dot is changed by changing the conducting time to the heat elements TH1-THn in this way.

Title: Optical fiber
Inventor: KOIKE YASUHIRO
IPC: C08F32/02
Filed: 1995-04-28
Abstract: PURPOSE: To prevent leaking of light by using a noncrystalline fluorine-contg. polymer having no C-H bond to constitute a refractive index distribution type optical fiber, and forming an outer layer with a fluorine-contg. polymer having lower refractive index than the inner layer. CONSTITUTION: The refractive index distribution type optical fiber consists of a noncrystalline fluorine-contg. polymer which does not substantially contain C-H bonds as a matrix. The optical fiber consists of concentric two layers of an outer layer and an inner layer having refractive index distribution. The refractive index of the outer layer is made lower by >=0.001 than that of the outermost part of the inner layer. The inner layer shows such refractive index distribution that the refractive index changes from 1.36 to 1.34 in the radial direction from the center and shows an almost parabolic curve. The outer layer in contact with the inner layer can suppress leaking of light by the difference of the refractive index from the outermost part of the inner layer.  The outer layer may be made of two or more layers as far as the refractive index of the outer layer is made lower by >=0.001 than the outermost part of the inner layer.

Title: Quasi-optimum output feedback controller
IPC: G05B13/02
Filed: 1992-03-11
Abstract: PURPOSE:To eliminate a need of an operator and to reduce the labor by developing a general controller capable of automatic design, which has universality of the range of application and has systematicness in the design process including a required numerical calculation method, because of difficulty in eliminating a need of the operator and reducing the labor in design and adjustment processes of a controller conforming to a conventional control method which include artifiial elements which cannot be omitted. CONSTITUTION:Dynamic relations (dynamic characteristics) between input and output of a control object system are expressed by an auto regressive moving average (ARMA) model. The controller is so designed that the response of the system forecasted based on this model traces an optimized finite settling locus determined at each time based on the quadratic-form evaluation function related to output and input while being switched, thus constituting a quasi- optimum output feedback controller.

Title: Thermal head
Inventor: KAKIZAKI YUJI
IPC: B41J2/335
Filed: 1989-04-24
Abstract: PURPOSE:To obtain a thermal head in which the need for a temperature sensor in addition to a heating resistor is eliminated by using a resistor having a temperature coefficient as the heating resistor for omitting a temperature sensor. CONSTITUTION:A heating resistor 11 consists of a resistor having a temperature coefficient which is connected to a power source 12 at one end and to a switch 13 at the other end. The temperature increase of the heating resistor 11 is controlled by changing the resistance value of the resistor 11. The ON/OFF operation of the switch 13 is controlled by a drive circuit 14. The switch 13 is turned ON by the application of a high level signal. By selecting a temperature coefficient A, the resistor reaches the same temperature independently of the temperature of the resistor at the time of a voltage application, and irregularities in temperature can be eliminated. The selective change of the temperature coefficient of the resistor can be realized, e.g. by applying a doping technique to a semiconductor. In this manner, a complicated control circuit is omitted, and printing without irregularities in density can be realized.
