Title: Ecl logic circuit
IPC: H03K19/086
Filed: 1991-11-12
Abstract: PURPOSE:To reduce power consumption without sacrificing a switching speed by connecting a P-channel MOS transistor(TR) to a bipolar TR of an ECL logic circuit forming a current switching circuit. CONSTITUTION:A gate of a P-channel MOS TR M1 connects to a base of a bipolar TR Q1 of a current switching circuit 1, its drain connects to a collector of the TR Q1, its source connects to a power supply, and when an input signal S changes to an L level, the TR Q1 is turned off, the TR M1 is turned on, a current ID flows momentarily and a parasitic capacitance of the collector of the TR Q1 is rapidly charged. Thus, even when a load resistance R1 is increased to secure a sufficient logic amplitude when a switching current IE is low, the channel resistor is sufficiently low the moment when the TR M1 is turned on, and the time constant is reduced. Thus, a leading time of an output signal A of the collector of the TR Q1 is reduced, and the power consumption is suppressed without sacrificing the switching speed via a large load resistor.

Title: Polishing pad
Inventor: HIROKAWA RYOICHI
IPC: C08J5/14
Filed: 1997-10-14
Abstract: PROBLEM TO BE SOLVED: To keep the effective area almost constant without nonuniformity of hardness, and efficiently polish a surface and an end surface of a wafer by decomposing a foaming agent of a microcapsule of a shell wall made of a high polymer material by heat of hardening reaction of a raw material of a base material, and forming foam by gas expanded by breaking the shell wall. SOLUTION: A large number of foam 3 is almost uniformly distributed over a base material 1 of a urethane resin selected from a high polymer material, and a part is exposed to a surface 2 of the base material 1, and forms a recess 4. A sub-raw material such as a hardening agent, a microcapsule to make foam and an abrasive material are added to a main raw material of the urethane resin of the base material 1, and are agitated up to being uniformly mixed. The main raw material and the sub-raw material start reaction when being mixed, and generate heat of hardening reaction. Gas by decomposing a foaming agent of the microcapsule by the heat of hardening reaction, expands, and a shell wall is push-expanded.  Since the foam 3 is uniformly distributed in a spherical shape, even if the recess 4 changes according to abrasion, the effective area is kept almost constant, and a surface and an end surface of a wafer can be polished with high efficiency.

Abstract: PURPOSE:To inspect the heat joint part without contacting by picking up an image of temperature variation on the reverse surface side of a substrate by an infrared video device when liquid which has a temperature difference is supplied to a cooling medium flow passage by switching and analyzing data on the picked-up temperature variation by a data processor. CONSTITUTION:Opening/closing valves 24 and 25 on a low temperature water side are opened so as to supply low temperature water of about 20 deg.C to the cooling medium flow passage 12 and opening/closing valves 22 and 23 on a low temperature water side are closed to circulate the low temperature water until thermal balance is kept. Then valves 22 - 25 are switched to supply and circulate high temperature water of about 80 deg.C to the flow passage 12, and the temperature variation on the reverse surface of a substrate 10 at this time is inputted as image information by the infrared video device 17. Then this information is processed by the data processor 18 and analyzed as temperature variation data in each constant section and if there is an area where the temperature rise is slower than in any other area, it is judged that the state of the heat joint part of an IC element 11 corresponding to the area is bad. Here, the circulation order of the high temperature water and low-temperature water is inverted and a judgement can be made from the time required for a temperature drop, thus performing the inspection in an actual state in either case.

Title: Overcurrent detector for power supply for printer
Inventor: WATAMURA HISASHI
IPC: G05F1/00
Filed: 1987-11-25
Abstract: PURPOSE:To eliminate the need for taking measures as to safety specifications on the downstream side of the output of a power supply, by dividing the output into at least two outputs so that the outputs have a fixed current. CONSTITUTION:A current flowing through an output terminal A is proportional to a voltage drop across a resistor 7. The voltage across the resistor 7 is divided by resistors 9, 10 and resistors 11, 12 to be an input to a comparator 5. Therefore, when the current flowing through the output terminal A exceeds a certain value, an output from the comparator 5 becomes zero. Similarly, when a current flowing through an output terminal B exceeds a value set by resistors 8, 9, 10, 13, 14, an output from a comparator 6 becomes zero. The outputs from the comparators 5, 6 are put into wired OR connection, and the resultant signal is inputted to an error amplifier of a PWM controlling IC 4 in a constant- voltage power supply 1. When the outputs from the comparators 5, 6 become 0V, the controlling IC 4 is used in the direction for lowering the output voltage of the power supply 1; with such a construction, an operation of restricting an overcurrent is realized.

Title: Heat insulated box
Inventor: SHINTANI KOSUKE
IPC: F25D23/06
Filed: 1990-10-31
Abstract: PURPOSE:To prevent deterioration of vacuum degree in an outer shell of a box body by removing gas invaded into the shell by an evacuator. CONSTITUTION:When gas is invaded into an outer shell 2 so that vacuum degree in the shell 2 is deteriorated, adiabatic performance of a box body 1 is gradually decreased. In this case, if a temperature difference  t between a detected temperature T1 detected by a first temperature sensor 10 and a detected temperature T2 by a second temperature sensor 11 becomes a predetermined value (t) or less ( t<=t), a controller 12 judges that the adiabatic performance of the body 1 is deteriorated, and operates in this case a vacuum pump 8 for a predetermined time. Since the gas invaded into the shell 2 is removed by the operation of the pump 8 and the vacuum degree in the shell 2 is raised, the decrease in the performance of the body 1 can be prevented and hence the performance can be maintained excellent.
