On the surface of the surface protective layer, required picture patterns, graphics, symbols, or the like are formed by using a vehicle of a water-insoluble resin as a printing layer. This transfer sheet is floated on a liquid surface. The printing layer and the surface protective layer in the transfer sheet are activated by an activator. A transfer medium is pressed down on the transfer sheet from above the liquid surface to be pressed against the transfer sheet. In this manner, the printing layer and the surface protective layer in the transfer sheet are transferred to the transfer medium. Thus, simultaneously with the transfer of the printing layer, the surface protective layer can be formed to protect the transferred printing layer.

Title: Motor speed controller
Inventor: YANO KOJI
IPC: H02P29/00
Filed: 1989-12-19
Abstract: PURPOSE:To increase speed quickly at start by regulating the speed through regulation of an output value from an acceleration/deceleration operating unit and detected rotational speed and motor current, while furthermore providing an observer and regulating the starting static frictional torque and starting current. CONSTITUTION:A speed set at a speed setter 11 is converted through an acceleration/deceleration operating unit 12 into a speed command value, and a speed detected through a speed detector 13 is regulated and inputted to a speed regulator 14. A current signal detected through a current detector 15 is added or subtracted to/from the output of the speed regulator 14, while furthermore output from an observer 21 is added thereto. The observer 21 receives static frictional torque of a motor 4, preset through a torque setter 22, a speed signal from the speed setter 13 and a signal from the current detector 15, and operates an estimated value of load torque. The observer 21 performs operation with a time constant set considerably lower than that of the speed regulator 14. By such arrangement, motor speed increases smoothly and quickly and reaches a predetermined speed in a short time.

Title: Rear surface projection type display device
Inventor: TERADA KATSUMI
IPC: G03B21/62
Filed: 1996-12-10
Abstract: PROBLEM TO BE SOLVED: To enable an observer to obtain more presence by forming a screen to be a concave surface with respect to the observer. SOLUTION: The diffusion screen 2 of the rear surface projection type display device is provided with a diffusion layer 3a formed to be a concave surface with respect to an observer A. The layer 2a can be formed by ruggedly embossing a transparent plate formed to be the concave surface or sticking a diffusion sheet to the concave surface of the transparent plate. When the screen 2 is constituted for the 45-inch screen, for example, the curvature of the concave surface of the layer 2a is set so that a gap L between a virtual plane surface X brought into contact with the central part of the layer 2a and the circumferential edges of the layer 2a in a left and a right directions becomes about 30mm.  Thus, since the layer 2a of the screen 2 is formed to be the concave surface with respect to the observer A, the observer A receives such feeling that he/she is surrounded by a video formed in a concave surface state and the presence is enhanced.
