Title: Multicolor thermal recorder
Inventor: NOGUCHI AKIO
IPC: B41J35/16
Filed: 1982-12-21
Abstract: PURPOSE:To enable miniaturization of the equipment by conveying a recording paper between a plurality of thermal heads arranged radially facing one another on one back roll while running an ink doner sheet at the tip of the thermal heads. CONSTITUTION:As a recording paper 3' is conveyed with the rotation of a back roll 104 until the tip thereof arrives near a first thermal head 113 at a first recording section 101, a first doner sheet 112 starts running at the same speed and positioning is done to perform a heat transfer recording of cyan in color. Then, as the tip arrives near a second recording section 102, a heat transfer recording of yellow in color is done with a second thermal head 123 and a second ink doner sheet 122. Subsequently, the paper is circulated to the first recording section 101 to record in magenta and in black at the second recording section 102 thereby enabling a multicolor recording with a heat transfer recording. Thus, the miniaturization of the equipment can be realized thereby allowing reduction in the cost.

Title: Ultraviolet-absorbing colorless transparent glass
Inventor: KOMIYA HIDETOSHI
IPC: C03C3/085
Filed: 1997-08-06
Abstract: PROBLEM TO BE SOLVED: To obtain the subject glass at lower cost more easily and more colorlessly than conventional ones. SOLUTION: This glass is obtained by incorporating 0.02-0.07 wt.% of erbium oxide as color fading agent in a soda-lime glass containing 0.3-0.6 wt.% of cerium oxide and <=0.05 wt.% of iron oxide. Incorporation of the cerium oxide affords this glass with ultraviolet light absorption effect. Yellowish color due to the iron oxide and cerium oxide can be corrected owing to the pale pinky color of the erbium oxide, getting virtually colorless. The color development of the erbium oxide is highly stable, being hard to be influenced by atmospheric change or an oxidizing agent such as the cerium oxide, thereby easily affording desired effects.

Title: Optical information recording carrier
Inventor: MATSUMURA SUSUMU
IPC: G11B7/24012
Filed: 1987-09-08
Abstract: PURPOSE:To simplify constitution and to improve accuracy by integrating a base material which has an optically high reflectivity region in at least a part of the surface and an information carrier which is recorded with information as an optical change in transmittance in correspondence to the read information. CONSTITUTION:This recording carrier is constituted by integrating the base material A which has the optically high reflectivity region in at least a part of the surface and the information carrier B which is recorded with the information as an optical change in transmittance in correspondence to the read information. High-density pit patterns are, therefore, obtd. and the information can be recorded as the optical change in the transmittance in the case of, for example, forming the information to be read to the information carrier B by forming a master mask and developing the same by a photographic reproduction process. Reproduction of the information is executed by reading the information as a difference in the contrast of the light which is transmitted through the information pit pattern part and is reflected by the high reflectivity region 2 of the base material A. The constitution is thereby simplified and the recording of the information pattern with the good accuracy over the entire surface of a card is enabled.

Title: Protective device for feed water pump
Inventor: MATSUDA MASAHIRO
IPC: F04D15/00
Filed: 1982-12-22
Abstract: PURPOSE:To prevent a feed water pump from overheating, by detecting a flow rate and a speed of rotation in the feed water pump, and performing the irreducible minimum of recirculating flow control, while checking a rise in the speed of rotation in time of said recirculating flow control or tripping the pump otherwise. CONSTITUTION:The output of a detector 8 for a speed of rotation in an output shaft of a hydraulic coupling 13 controlling the speed of rotation in a feed water pump 1 is converted into a minimum recirculating flow signal corresponding to the speed of rotation at that time in a flow setter 9 by way of a deviation operator 12 and impressed on a relay 10. On the other hand, as a feedback circuit, a signal out of the relay 10 is converted into the speed of rotation corresponding to a flow rate with a revolution operator 12, comparing it with the output of the detector 8, and when it comes to an expression of actual revolution > operation revolution, this signal is fed to a motor 14 and tripped. Next, when a pump speed is slowed down, a signal out of the deviation operator 12 is inputted into a control commander 16 and at this time the priority order of these signals is determined, transmitting this signal to a control drive 15, then the speed of rotation in the pump is slowed down to some extent whereby overheating and any damage are prevented.
