Title: Cooling vessel for infrared detector
Inventor: HAMASHIMA SHIGEKI
IPC: G01J5/02
Filed: 1990-08-21
Abstract: PURPOSE:To prevent deviation of an optical axis substantially by providing a means of fixing the part of an inner tank near an infrared-ray detecting element to an outer tank and by constructing the outer tank, the inner tank or a cylindrical member so that it can be extended and contracted partially. CONSTITUTION:An inner tank 8 is formed by putting in one body the main body 8a of the inner tank filled up with a refrigerant inside and an element mounting part 8b provided in the part of the main body 8a facing an infrared- ray transmitting window 2, and an infrared-ray detecting element 6 is fixed on the mounting part 8b. The mounting part 8b has an external shape like a bellows, and a means 12 of fixing the part of the inner tank 8 near the element 6 to an outer tank 4 is a fixing rod 14 of which the upper and lower ends are fixed to the mounting part 8b and the bottom part of the outer tank 4 respectively. The element 6 is not displaced when the inner tank 8 is displaced relatively in relation to the outer tank 4, since the mounting part 8b changes in shape. Accordingly, there is no possibility of occurrence of deviation of the optical axis of an infrared detector, and the necessary optical characteristics of the detector can be obtained.

Title: Signal inversion detecting circuit
Inventor: KASHIMURA MASAHIKO
IPC: H03K5/00
Filed: 1985-09-30
Abstract: PURPOSE:To decrease number of transistors (TRs) constituting the titled circuit by turning on a couple of TRs constituting an inverter simultaneously while a signal to be detected is inverted and turning on teh one TR and turning off the other afterward. CONSTITUTION:A current through circuit comprising series connection of TRs P0, N0 and a circuit B sensing and amplifying the current are connected by a terminal (a). When the input A0 is logical '1', since the TR N0 is turned on and the TR P0 is turned off, the current I is zero and no current flows to a TR PY and an output (b) goes to a low level. When the input A0 is inverted from logical '1' to logical '0', a time when both the TRs N0, P0 are turned on exists, the level of the terminal (a) is decreased by the current I, the TR PY is turned on and the output (b) goes to a high level. The current I is temporary, the TR PY is turned off and the output (b) goes to a low level by a resistor R. Thus, the signal inversion is detected by a couple of TRs and the number of the TRs is decreased.
