Title: Device and method of converting ecl signal into cmos signal
Inventor: ROBAATO JIEI BOSUNIYATSUKU
IPC: H03K3/356
Filed: 1991-09-20
Abstract: PURPOSE: To improve a time required for conversion by receiving a signal in a first prescribed logical level range, converting it into a second logical level in a converting circuit which is operated by a dynamic reference signal generated in the converting circuit. CONSTITUTION: The high voltage of a node B applied to the gates of transistors M12 and M15 of an ECL/CMOS converter establishes the conduction of a high level, and the low voltage of a node A applied the gates of transistors M13 and M14 relatively establishes a low level. As a result, the voltage is pulled-up to an intermediate voltage, and a reference voltage applied to the gate of a transistor M10 is made larger than a static reference voltage. Thus, when the node A has the low voltage, the transistor M10 is biased so as to be further speedily switched or turned off.

Title: Manufacture of thin film light emitting diode
Inventor: KOBAYASHI SATORU
IPC: H01L33/42
Filed: 1993-09-29
Abstract: PURPOSE:To avoid the mutual diffusion of component elements between laminated layer films in the crystallization process of super-lattice produced layer by crystallizing the quantum well layer and the part near the pole piece thereof by using light. CONSTITUTION:Specific part of a light emitting layer is irradiated with visible rays having photon energy not exceeding the level corresponding to the optical forbidden band width of a quantum well barrier layer but exceeding that of the quantum well layer to be crystallized. Thus, most of the visible rays irradiated on the light emitting layer are absorbed into the quantum well layer but not to be absorbed into the quantum well barrier layer to be transmitted. At this time, a part of photons absorbed into the quantum well layer contributing to the non-radiation transient process of the component atoms generate heat so as to crystallize the quantum well layer by using the generated heat when a lot of photons are incident. Furthermore, the super lattice structure does not reach the thermal equilibrium state causing the thermal diffusion after the local heat generation so that the mutual component elements of the quantum well layer and the quantum well barrier layer may not be diffused at all.

Filed: 1995-09-21
Abstract: PROBLEM TO BE SOLVED: To attempt to improve the heat exchange effectiveness and to reduce the weight of an icemaking panel by laying the panel formed with a flow passage between the connecting parts of a plurality of metal plates on the entire space for forming an ice link, and passing secondary refrigerant through the passage. SOLUTION: The cold heat of secondary refrigerant circulated in icemaking panels 12 is transferred to the water expanded at the upper side to freeze it, thereby forming an ice link. The panels 12 are so formed with flow passages 20 between the connecting parts of upper and lower corrugated steel sheets 16 and 18 as to feed the refrigerant through the passages 20. Thus, since the cold heat of the refrigerant is transferred from the entire surface of the sheet 16 formed in a waveshape to the water of the upper side, the heat exchange effectiveness of the refrigerant with the water is remarkably improved. A reinforcing steel sheet 24 is coupled to the lower side of the lower sheet 18, and flow passages 20a are also formed between the sheet 24 and the sheet 18. Thus, the heat exchange effectiveness is further improved.
