Title: Coil type passage for heat exchanger and heat exchanging coil unit employing said passage
Inventor: TANAKA BUNKICHI
IPC: F28D1/047
Filed: 1987-03-07
Abstract: PURPOSE:To improve the flow of air through gaps between respective windings of a coil and permit the pitch of one winding of the coil to be reduced, by a method wherein the pipe of the coil is provided with a flat section and the major axis of the section is intersected with the central axis of the coil orthogonally or the same is intersected with an axis orthogonal to the central axis of the coil by an acute angle. CONSTITUTION:The section of a pipe 11 is flat and the major axis of the section is intersected orthogonally to the central axis of a coil 12 or the same is intersected with an axis orthogonal to the same central axis by an acute angle. The section of the pipe 11, forming a flow passage, is flat with respect to the flow direction of air or a direction of intersecting with the central axis of the coil 12, therefore, airflow, shown by arrow signs in a diagram, is smoothened, whereby efficient heat exchange between refrigerant, flowing through the inside of the coil, and air, cooling the outside of the coil, may be effected. On the other hand, the pitch of the coil 12 may be widened by a length corresponding to a difference between the length of the major axis and the same of the minor axis of the section of the pipe 11. In other words, the winding pitch of the coil 12 may be dense when the width of the gap between respective windings is the same.

IPC: G06F1/00
Filed: 1984-03-21
Abstract: PURPOSE:To attain a combination of a memory for development of programs and a microcomputer by adding a battery, i.e., a power supply to a microcomputer for development of programs. CONSTITUTION:A battery 15 serving as a power supply and a battery holder 16 are set at the upper part of the main body 11 of a microcomputer for development of programs. Then the power is supplied to the computer 11 from an external power supply via a power supply line. While the power is supplied to a memory 13 for storage of programs from the battery 15. In such a constitution, it suffices to supply the power only to the computer 11 from a power supply of an applied product using a 1-chip microcomputer. This prevents a malfunction due to the insufficient capacity of a power supply.

Title: Display data control circuit
Inventor: MATSUSHITA AKIRA
IPC: H04N7/03
Filed: 1988-03-08
Abstract: PURPOSE:To shorten the operation time of the title circuit from the data reception starting time to the data display starting time by fetching transmitted signals at high speed by processing the data to be fetched during a non-display period in the form of codes, as it is. CONSTITUTION:In a teletext system, a microprocessor (CPU) 11 decodes transmitted data and discriminates whether the transmitted data are of the pattern form or code form or colored data. When the data are of the code form, the code data are stored in a character code memory 22 as they are through a bus 12 and gate circuit 21. Therefore, it is not required for code-form data especially to write the data in a pattern memory section after converting the data into pattern data at a character memory. Therefore, the display processing time of this circuit can be shortened.

Title: Pressed breed and machine therefor
Inventor: OOSATO AKIRA
IPC: A01F15/04
Filed: 1979-04-29
Abstract: PURPOSE: In title machine, fibrous vegitables such as hay are made entangled with one another on the surfaces, thus preventing the deformation of the pressed products by naturally getting loose.  
     CONSTITUTION: Hays of appropriate length are uniformly packed in press cylinder d. Then, cutter d is forced through slit h on the wall surface of cylinder d to make cut c and then removed. Plunger e is forced into the center of cylinder d. Since a gap f is formed between the above plunger e and the inner wall of cylinder d, the  center part b of the hays in cylinder d is made flatten and entangled in the space between the top surface of the plunger e and the bottom wall of cylinder d to form  tightly pressed hays. Each of hays protruding toward the gap f entangles with other  hays one another on the whole surface a, which protects the inside to prevent the  deformation of the pressed hays.
