Title: Printing method in thermal printer
Inventor: HISAIE AKIRA
IPC: B41J2/36
Filed: 1983-12-24
Abstract: PURPOSE:To prevent the heat accumulation of a heat generator and to obtain good printing quality while obtaining a long life head, by applying energy corresponding to almost 1/N of printing energy required in printing one line of heads to an N-lines of heat generating element groups and performing overlapped printing to finish one character. CONSTITUTION:A head, wherein N-lines of heat generating element groups each arranged in a linear state are mutually arranged in parallel at dot pitches of characters to be printed, is mounted and printing energy corresponding to almost 1/N of that required in printing one line of the heat generating element group is imparted. In this case, overlapped printing is successively performed by N-lines of the heat generating element group to perform printing corresponding to one character. For example, because one character is finished by performing the printing of one character by overlapped printing due to two front and rear lines of heat generating element groups 21, 22, the printing energy to each heat generator can be brought to almost 1/2 of printing energy E of one line and, because the temp. of each heat generator is suppressed to a fairly low degree and cooled sufficiently, good printing quality is obtained and the life of the head can be also prolonged.

Filed: 1989-09-28
Abstract: PURPOSE:To prevent a shutter from being frozen owing to a back flow of cold air by providing the shutter disposed on a third chamber cold air introdiction passage and a dam part and a floor surface for blocking dew. CONSTITUTION:Cold air cooled by a cooler 6 is blown out by a fan motor 7 to cool freezing chamber 2. Further, the cold air passage through a cold air communication passage 8 and is adjusted in the discharge amount thereof by damper changeover means 9 of temperature regulator means 10, and further enters a refrigerator chamber 3 for its cooling. On the other hand, the cold air adjusted in the discharge amount of the same by the damper changeover means 9 of the temperature regulator means 10 flows out to an cold air discharge passage 11 and passes through the inside of a third chamber cold air intruduction passage 12 provided with the cold air discharge passage 11 and flows out from cold air discharge outlet 14 for cooling the third chamber 5. Thereupon, the cold air guides dew formed by use of a slope part in the third chamber cold air introduction passage to a predetermined location. Hereby, the dew is prevented from flowing by the dam. Thus, there is avoided adhesion of the dew in a gap between a cold air interruption plate on the shutter and the third chamber cold air introduction passage to prevent the shutter from being frozen.

Title: Pulse width modulation circuit
Inventor: OGAWA KIYOTAKA
IPC: H03K7/08
Filed: 1986-10-24
Abstract: PURPOSE:To obtain a stable output characteristic with a simple circuit constitution by connecting a constant voltage diode in series between a voltage source and a triangle wave oscillating circuit in a modulation circuit provided with the triangle wave oscillation circuit and a comparator circuit. CONSTITUTION:Constant voltage diodes 10A, 10B are connected in series between a voltage source and the triangle wave oscillating circuit 1. The other configuration is the same as that of a conventional circuit. So long as the diode 10 is used at the breakdown region, the voltage is held at the breakdown voltage over a wide current range. Thus, even with the voltage of the voltage source fluctuated, the voltage of the voltage source is compensated by the constant voltage diodes at a constant value and since the linearity with the control signal (continuous input signal) is kept in an excellent way, the control accuracy is improved.

Title: Prevention of evaporation in dam
Inventor: TSUKIGATA HIDEJI
IPC: E02B7/00
Filed: 1990-09-20
Abstract: PURPOSE:To prevent water loss due to the evaporation by floating sheets like foamed polyethylene on the surface of the water reservoir of a dam. CONSTITUTION:A large volume of water is evaporated in the outdoor receiving the direct sun light when the air verocity on the water surface is added. On calculating of about 1km<2> in an area as wide as a dam for about 2mm thickness of waterlevel evaporation, the water loss due to evaporation reaches about 2000 tons during 24 hours. In order to prevent this evaporation loss, foamed polyethylene sheets with a high heat-insulating property are directly floated on the water surface. In this way, the evaporating area on the reservoir surface is decreased as well as possible to reduce the evaporating loss.
