Title: Cold and hot heat extracting method and device in ice cold accumulator
Inventor: KAMEDA YOSHIMUNE
IPC: F25D17/02
Filed: 1987-06-30
Abstract: PURPOSE: To take out cold heat efficiently by supplying heat carrier to the panel type ice making coil of an ice cold storage water tank in order to melt ice and then melting ice by supplying cooling water of an air conditioner through the ice cold storage water tank while passing heat carrier to the ice making coil. CONSTITUTION: The panel-type ice making coil 4 of an ice cold storage water tank 3 is formed by bending a heating tube 16 into a plurality of stages and closing the gap between respective stages of heating tube with a heat transfer plate 17. At the time of cold heat take-out operation, an ice making heat pump 1 is switched to heating operation and a refrigerant is heated to produce a heat carrier before stopping the heat pump 1. Three-way valves 5, 6 and 8 are then operated to produce a flow shown by an arrow and when a brine pump 5 is operated, ice is melted from the panel side through circulation of heat carrier in the initial melting stage and, at the same time, ice is melted from the outside of the panel through circulation of air conditioning water through ducts 27, 28.  Since contact area between ice and the air conditioning water increases to increase flow rate of the air conditioning water, ice melting efficiency is enhanced drastically. Operation on the heat carrier is stopped at that moment and ice melting is sustained only through circulation of the air conditioning water thus sustaining high cold heat take-out capacity.

Title: Trouble detector for coil
Inventor: SAITOU SHIGERU
IPC: G01R31/72
Filed: 1981-10-15
Abstract: PURPOSE:To handle the trouble in a coil current control circuit quickly while protecting it by detecting the disconnection and short-circuit of a coil in the circuit having a feedback circuit of a coil current. CONSTITUTION:Disconnections of a coil 3a are possible at points A, B and C, where a short-circuit occurs at the points A and C. When a disconnection occurs, the voltage VD of the resistance RD zeros and the voltage VS rises to let current IF flow. When a short circuit occurs, the VS falls because of VS=VD. But as current fails to flow through the coil 3a, command from a command section 1 increases and the VD itself rises. When higher and lower levels are represented by H and L as compared with the reference value, the voltages of the coil are as shown by the table. This facilitates the determination on whether the coil is normal or in trouble.

Abstract: PURPOSE:To decide an optimum mounting order simply and in a short time and to easily deal with even a change in various mounting conditions by a method wherein, on the basis of a condition which decides a mounting order, a mounting region is divided continuously until an optimum condition becomes self-evident, self-evident mounting orders are joined and the whole mounting order is decided. CONSTITUTION:In order to satisfy a condition to make the total movement distance between mounting points shortest, a mounting region on a printed-circuit board is divided into two region as a region 4 and a region 5 in the X-direction so as to halve the number of mounting points P by a dividing line 1. Then, the divided regions 4, 5 are divided into two each in the same manner, and a division processing operation is repeated until the mounting order which reduces the movement distance between mounting points P, P to a minimum becomes self-evident. As a result, the mounting points P inside each region are reduced to two points or three points, the mounting order becomes a triangle or a line segment, and the mounting order inside each region becomes self-evident. Then, the divided regions are united reversely until the divided regions vanish, the region 4 and the region 5 are united lastly and the mounting order of all the mounting points P is decided.
