Title: Freeze storage detecting sensor for food or the like
Inventor: KONDO SATORU
IPC: G01K11/00
Filed: 1989-12-13
Abstract: PURPOSE:To easily recognize a state wherein an article is not exposed to above a freeze storage temperature in a distribution stage by adding and using the detecting sensor made of a shape memory alloy, which has a glass dislocation point above the freeze storage temperature and below the room temperature, directly or indirectly for the article. CONSTITUTION:A strip made of the shape memory alloy is heated above its softening temperature and corrugated, and the strip is as shown in (a) in the shape memory state. Then the corrugated strip is heated above the glass dislocation point and cooled below the glass dislocation point while held in a flat plate shape, and its fixed state is as shown in (b). Then when the flat plate strip glass is exposed above the glass dislocation point, the stored corrugation shape is reproduced. Thus, an abnormal shape which is never obtained in the distribution stage is stored previously in the detecting sensor to easily recognize whether or not the article is exposed to temperature above set temperature.

Title: Driving circuit
Inventor: OKUTSU MITSUHIKO
IPC: H03K17/62
Filed: 1987-12-21
Abstract: PURPOSE: To obtain sufficient current driving capability while securing operation in the safe operation area of NPN by providing a resistance between a low- voltage power source terminal and a low-voltage power source wire to a buffer circuit. CONSTITUTION: The base currents of NPN transistor's(TR) SN (SN1 SNn ) are supplied from the low-voltage power source terminal VCC through P-MOSFET MPs (MP1-MPn) in the buffer circuit, and there is a difference in the total of the base currents of elements SN which is an integral multiple of the number of channels of a driving circuit between load driving and load discharging. Therefore, when all the elements SN are on, i.e., in the safe operation area, the voltages between the gates and sources, and drains and sources of the elements MP supplied with the base currents drop because of the voltage drop across the resistance R provided between the terminal VCC and buffer circuit B, so the outputs of the elements MP, i.e., the base currents of the elements SN decrease to suppress sink currents of the elements SN. Therefore, the safe operation area can be protected.
