Title: Heat collector of water heater that utilizes solar heat
Inventor: NAMIKOSHI TAKESHI
IPC: F24J2/04
Filed: 1980-11-29
Abstract: PURPOSE: To obtain the captioned heat collector wherein the heat collecting plate is divided by a heat transfer partition into an upper shell and a lower shell with one end  having a communicative opening so that with a simple constitution the radiation of  heat can be reduced and the heat collecting efficiency is increased.   
     CONSTITUTION: Water is fed through a water supplying port 1 provided in one end of  the lower shell 6 of the heat collecting plate A that constitutes the heat collector C,  and passes through the communicative opening 12 into the upper shell 13 that is difined by the heat transfer partition 11. Solar heat passed through the transparent plate  B heats an air layer D and the heat collecting plate A to raise the temperature of water in the upper shell 13, and part of the heat is transmitted to the water in the lower  shell 14 through the partition 11. In this latter case, since circulation of water does not  occur between the upper and lower shells 13, 14, heat radiation from the heat collecting  plate A and the transparent plate B is reduced. In the meanwhile, the heated water in  the upper shell 13 is delivered from a hot water delivering port 5 suitably, and as the delivery of the hot water is carried out from the upper shell 13 from the lower shell 14  in the laminer flow state, the hot water has a uniform temperature distribution and is  delivered effectively.

Title: Printing head
Inventor: OGATA HIROYUKI
IPC: B41J2/28
Filed: 1990-06-27
Abstract: PURPOSE:To restrain breadthwise flection, as well as breadthwise oscillation, of an arm and to prevent therewith breakage of the arm by providing an arm guide that guards the arm from the breadthwise force acting on the arm when printing is operated. CONSTITUTION:An armature 8 is normally (when a device is not in operation) attracted by magnetic force of a permanent magnet 1 to one end of a magnetic core 3, and thereby a plate spring 10 is flexed. As a coil 6 is electrified through a relay terminal on a substrate 7, the magnetic force of the permanent magnet 1 is overcome by magnetic flux generated by the coil 6. The armature 8 is then separated from the magnetic core 5 by energy accumulated in the plate spring 10, and move printing wires 4 through arms 5 that are united with the free end of the armature 8. As the electric current to the coil 6 is cut off and the magnetic flux is killed therewith, the armature 8 comes in contact again with the magnetic core 5 by the magnetic force of the permanent magnet 1. The arms 5 transmit energy through themselves to the printing wires 4 for each of printing motions, and the arms 5 oscillate breadthwise (in the direction intersecting the direction of the printing motion) on every printing motion. When the oscillation exceeds a specified amplitude, arm guides 14 start acting to restrain the breadthwise oscillation of the arms 5.
