Patent JP-H09105567-A (JP)
Title: Freezer
Inventor: NAKABO TADASHI
IPC: F25B49/02
Filed: 1995-10-06
Abstract: PROBLEM TO BE SOLVED: To accurately and properly detect refrigerant leakage. SOLUTION: A freezer having a supercooler 4 detects inlet refrigerant temperature T1 thereof and outlet refrigerant temperature T2 thereof noticing that a saturated liquid refrigerant stored in a receiver 3 flows into an inlet of the supercooler 4 at all times provided a refrigerant amount encapsulated in a cycle is normal one irrespective of variations of operation conditions. The apparatus further estimates the degree of refrigerant supercooling based upon a difference between the detected refrigerant temperatures (T1-T2), and if the degree of refrigerant supercooling is reduced to a set value or lower, it judges that there is existent refrigerant leakage.

IPC: H01L29/80
Filed: 1985-11-20
Abstract: PURPOSE:To decrease the deterioration in noise figure and to enable the dielectric strength to be lowered to a value close to the value of a gate bias applied typically, by utilizing an aperture used for forming a P<+> type second diffusion, for the purpose of forming a depletion layer region so as to have a lower concentration of impurity during operation and to have a high concentration during a breakdown. CONSTITUTION:A diffusion region 5 is formed under a region where a diffusion region 3 having one type of conductivity overlaps with a second diffusion region 4 having the opposite type of conductivity, and the diffusion region 5 has a lower concentration of impurity than that of the region 3. Thus, an N<+> type section having a higher concentration and an N-type section having a lower concentration are provided. A part of the higher-concentration section provides a region where a depletion layer is extended when a breakdown occurs. The N-type lower-concentration region 5 is located between the P<+> type diffusion region 4 and the N<+> type higher-concentration region, and an impurity concentration of the whole depletion layer is lowered equivalently thereto during operation. Further, a P-type diffusion region 7 is provided between the regions 5 and 5. Thus, two diodes 21 connected to a gate 1 (G1) through the two N<+> type first diffusion regions 3 and the P<+> type second diffusion region 4 are formed in an N<+>-P<+>-N<+> type as a gate protecting diode 1.

Title: Semiconductor integrated circuit
Inventor: TAKAHASHI KATSUYUKI
IPC: G01R31/28
Filed: 1993-10-19
Abstract: PURPOSE:To allow inspection even of a large scale integrated circuit by inserting a pull-up or a pull-down resistor having error within a specified ranged between an I/O pin and an internal circuit. CONSTITUTION:The semiconductor integrated circuit comprises a package 1, an internal circuit 2, input pins 3, output pins 4, a power supply pin 5, a ground pin 6, and a pull-up resistor 7 having a known resistance with error within about 33%. At the time of inspection, power is not fed to the pin 5 but an inspection signal is fed only to the input pin 3 and thereby the current flowing through the circuit 2 is negligible. Consequently, the integrated circuit can be regarded as a simple combination circuit of resistors. The resistance is measured by comparing with a reference resistance through a high accuracy operational amplifier. Assuming all resistors 7 have a resistance (r) and the measured resistance is R, the input pin 3 is decided normal if R=r is satisfied when the resistance is measured between the points (a) and (c). The output pin 4 and the input pin 3' are decided normal if R=r/2 is satisfied when the resistance is measured between the points (a) and (b) Consequently, insufficient open circuit can be inspected easily even for a large scale circuit 2.
