Title: Absorption type refrigerating machine
Inventor: MAENO MASASHI
IPC: F25B37/00
Filed: 1996-05-27
Abstract: PROBLEM TO BE SOLVED: To prevent the enlargement of a vessel and a refrigerating machine and secure air-tightness, resistance to pressure or the like by a method wherein any one of an absorber, a reproducer, a condenser and an evaporator is constituted of an independent plate type heat exchanger. SOLUTION: An absorber 1, a preheater 2, a reproducer 3, a condenser 4 and an evaporator 5 are constituted of an independent plate type heat exchanger respectively. Thick solution, extracted from the absorber 1, is preheated in the preheater 2 and, thereafter, is heated in the reproducer 3 to obtain thin solution. Refrigerant gas and the thin solution are sent into a gas/liquid separator 6 and refrigerant gas, separated from the thin solution, is sent into the condenser 4. On the other hand, the thin solution, from which the refrigerant gas is separated in the gas/liquid separator 6, preheats the thin solution in the preheater 2 and, thereafter, is joined with the refrigerant gas, evaporated in the evaporator 5, in a mixing unit 7, then, enters the absorber 1 and is changed into thick solution by absorbing the refrigerant gas.  Thin solution is injected from an injection nozzle 8 in the mixing unit 7 and enters the absorber 1 after being changed into injection stream after being joined with the refrigerant gas, then, is changed into thick solution by effecting heat exchange between cooling water through a plate 1A.

Title: Impatt diode
Inventor: KANDA TAKASHI
IPC: H01L29/864
Filed: 1980-11-05
Abstract: PURPOSE:To raise efficiency of an oscillation output of an element by evaporating gold on the outer periphery and the rear surface of the element part and by metallizing the side surface of the element part. CONSTITUTION:Gold is evaporated on the rear surface and the side surface of a ring type IMPATT diode of P<+>NN<+> having an active layer 9 of P<+>N formed by diffusing P<+> into a semiconductor part 2 having N<+>N, and thereby a metallized part 1 is formed. With the junction part placed down, this is contact-bonded  to a radiating plate. Hereby, since the side surface has been metallized, registance of the side surface is lowered, and dropping of an oscillation output caused  by a skin effect is prevented along with prevention of the invasion of moisture  and impurities from the surface, thus deterioration of the characteristics is improved.

Title: Contact anomaly detection circuit
Inventor: FUKAGAWA HITOSHI
IPC: G05D23/24
Filed: 1978-12-15
Abstract: PURPOSE: To detect immediately anomaly of a relay contact to break a power source and improve safety by operating AND between the signal voltage from a temperature control circuit using a face thermosensitive element and the voltage dependent upon a resistance connected in parallel to the contact relay.  
     CONSTITUTION: The temperature of face heating unit 1 is detected as the impedance of face thermosensitive element 2 having a temperature impedance characteristic such as nylon by signal detection circuit 12. Switching circuit 30 consisting of inverters 26 and 27 and resistance 20 is operated by this output, and transistor Tr17 is turned on and off to control relay coil 4, thereby switching relay contact 5. In case that contact 5 is welded by some cause, the temperature of heating unit 1 rises, and the output of inverter 26 becomes L-level. At this time, the output of inverter 28 becomes H-level to turn on Tr18 because no voltage is generated in resistance 22 connected in parallel to contact 5, and resistance 8 is heated to fuse temperature fuse 9, thereby stopping power supply to heating unit 1.
