Abstract: PROBLEM TO BE SOLVED: To improve music selection efficiency by making selectable from the composition data registered beforehand as personal repertories when KARAOKE (orchestration without lyrics) is enjoyed. SOLUTION: In a KARAOKE terminal device 30, when the ID data are inputted from a controller 32 to be sent to a reproducing device 31, the reproducing device 31 transmits the ID data to a registered data base 10 of a network 40 to request transmission of a music code. Then, the device 31 displays a table of the corresponding music data on a display device 33 based on the received music code. A user specifies a required music referring to the display of the display device 33. Then, when a command specifying the music is inputted from the controller 32, the reproducing device 31 transmits the music code to a host station of the network 50 to request the distribution of the corresponding music data. In such a manner, the received music data are reproduced.

Inventor: ARAKIDA TAKEO
IPC: B44D3/02
Filed: 1995-11-16
Abstract: PROBLEM TO BE SOLVED: To make it possible to effectively and easily prepare colors lightly and to easily release even if solidified colors by coating at least one surface of a plate-like foamed base material with an ionizing radiation curable resin paint, and then emitting ionizing radioactive rays to form a cured film. SOLUTION: After at least one surface of a plate-like foamed base material 1-1 (2-1) is coated with an ionizing radiation curable resin paint, it is emitted with ionizing radioactive rays to form a cured film 6, thereby forming a pallet 1 or 2 for colors. In this case, a hard foamed synthetic resin plate having a skin layer 3 on the surface is cut in a pallet state for the colors, and used as the base material 1-1 (2-1). A carrier 5 of a thin film made of PET is interposed, and laminated with an adhesive or a pressure-adhesive 7. Then, the flatness is further improved. The resin paint is formed of a radical polymerization type paint made of an acrylic oligomer. When a white pigment is filled in the foamed resin base material 1-1 (2-1), it becomes the same white as the color of the picture material, and the color of the paints becomes natural.

Abstract: PROBLEM TO BE SOLVED: To output optical pulse trains with a desired frequency interval, regardless of the band width of optical spectrum of reference light sources and reduce the harmonic order of next stage laser for the reference light source for preventing injection synchronization at an order before and after the target harmonic order. SOLUTION: Optical clock trains from a reference light source 2 are combined two times, through a semiconductor laser 4 via an optical combination circuit 3 and through a semiconductor laser 6 via an optical combination circuit 5, to obtain outputted optical pulse trains from a semiconductor laser 6. The optical clock trains are combined in two stages, so that the bandwidth of inputted optical pulse train is made larger than the frequency interval of the outputted optical pulse train at each stage. Therefore, the bandwidth of optical pulse train in the reference light source 2 need not be made larger than the frequency interval of optical pulse train in the semiconductor laser 6. Furthermore, the harmonic order of the semiconductor laser 6 with respect to the reference light source 2 is divided into two stages, and the harmonic orders at respective steps are reduced.

Abstract: PROBLEM TO BE SOLVED: To prevent the drop of cooling performance of a subcooling zone by the passage of hot air, in a liquid receiver integrated refrigerant condenser which has a supercooling zone. SOLUTION: This refrigerant condenser is equipped with a first condenser 35 arranged above and the second condensers 37 and 38 arranged below, and a supercooling zone 36 is arranged between the first condenser 35 and the second condensers 37 and 38. Accordingly, even if phenomena occur such as that the hot air having passed a refrigerant condenser 2 passes under the refrigerant condenser and is dragged again in the upstream side of the refrigerant condenser at the time of idling for waiting for signal of a vehicle, the hot air ceases to be dragged in the section of installation of the supercooling zone 36 since the supercooling zone 35 is arranged above the second condensers 37 and 38. Also at idling, this can keep the cooling performance of the subcooling zone 36 good.  Besides, this can raise the cooling effect of the supercooling zone 36 by positioning the supercooling zone 36 in the vicinity of the center high in wind velocity distribution of the cooling fan.
