IPC: G01L11/00
Filed: 1995-10-12
Abstract: PROBLEM TO BE SOLVED: To make it possible to simply measure the internal pressure of a vessel at a low cost by the previously obtained relationship between the resonance frequency and the internal pressure of the vessel by exciting the vessel and measuring the resonance frequency. SOLUTION: The metal drum, to which a top plate 2 and a base plate 3 are fixed at a step 1, is heated at a step 2, then the outer surface is coated, and heated at 65 deg.C for 15min in a drying furnace. Then, dehumidified air is introduced into the vessel, and a large plug 4 and a small plug 5 are closed. Thereafter, it is naturally cooled to the ambient temperature at a step 3. After cooling, the pressure in the drum becomes lower than the atmospheric pressure. The pressure change in the drum is measured by a vacuum pressure gage. The internal pressure of the drum which cannot hold the airtightness is near the atmospheric pressure as compared with the drum which can hold the airtightness. Since the resonance frequency generated by hitting the cover of the vessel and the internal pressure in the drum have a predetermined correlation, the airtighness of the drum can be inspected.

Title: Automatic white balance correcting device
Inventor: MORIMOTO DAISUKE
IPC: H04N9/04
Filed: 1991-10-14
Abstract: PURPOSE:To always execute optimum white balance correction independently of the quantity of incident light. CONSTITUTION:A noise level detecting circuit 15 detects noise levels included in color difference signals (R-Y signal (g), B-Y signal (f)) from an AGC control voltage (q) outputted from an AGC circuit included in a process circuit 3 and outputs a noise level value (r). AB-Y suppression judging circuit 16 compares the value (r) with a B-Y start value (k), and when the value (r) is larger, outputs a B-Y suppression signal (s). A B-Y signal suppressing circuit 18 reduces the gain of the B-Y signal (f) based upon the signal (s) and reduces a noise component included in the signal (f) so that a noise component included in a B-Y signal integrated value (i) is smaller than the value (k). Similar processing is applied also to the R-Y signal (g) by means of an R-Y suppression judging circuit 17 and an R-Y signal suppressing circuit 19.
