Abstract: PURPOSE:To prevent an abnormal condition such as incomplete combustion, etc., from happening by a method wherein at a part or the whole area of the air inlet out of an air port for combustion and air inlet for air suction, a lint filter is provided, and a filter is not provided at the air port for combustion as the constitution of the clothes dryer. CONSTITUTION:The air port for a heating chamber 41 consists of a first opening 61 on the rear end surface of the heating chamber 41, a second opening 62 which is located above the first opening 61, a plurality of third openings 63 in the vicinity of the lower end of a tilted surface 41a at the downstream side of the heating chamber 41, a fourth opening on the wall surface which is confronted with the third openings 63, and a plurality of fifth openings 65 on a connecting part 43, which are located in the vicinity of the connecting part to the heating chamber 41 and between the heating chamber 41 and a discharge chamber part 42. The combustion exhaust air from a gas burner unit 31 is mixed with cold air from an air inlet by a fan device, and hot air is made. Since there is no lint filter at an air port for combustion 3a, dust and dirt, etc., in the air are hard to adhere, and dust and dirt, etc., always adhere to a lint filter L which is provided, e.g. at the second opening 62, and when the dust and dirt, etc., reach a specified quantity, the quantity of the cold air becomes relatively smaller to the combustion exhaust air quantity, and the temperature of the hot air ascends, and the abnormal condition is prevented from happening by detecting the ascent by a fed air temperature sensor.

Title: Motion detection circuit for television display screen
Inventor: FUJITA SATOSHI
IPC: H04N9/77
Filed: 1988-12-30
Abstract: PURPOSE:To avoid the erroneous detection of nonexistent motion attending with the leaking-in of a chrominance signal by providing an inter-adjacent line correlation detection part to detect the degree of correlation between the adjacent lines of a video signal and to supply a control signal, which lowers the synthesizing ratio of the chrominance signal to a motion detection signal, to a final synthesizing part. CONSTITUTION:A first motion detection signal is generated by respective comb-line filters 3 and 4 based on the inter-adjacent frame differential of a luminance signal, for which it is completed to remove the chrominance signal. To this first motion detection signal, since a second motion detection signal is generated based on the inter-frame differential of the video signal before Y/C separation, interference by the leaking-in of the chrominance signal is easily generated in comparison with the first motion detection signal. Thus, concerning the inter-frame differential, coring processing is executed so that a signal can be regarded as zero level as long as the signal does not exceed a prescribed level. After that, the signal is supplied to a maximum value selection circuit 11. Accordingly, the first motion detection signal is normally larger than the second motion detection signal and the first motion detection signal selected by the maximum value selection circuit 11 is defined as the motion detection signal of the luminance signal.

IPC: G01N15/00
Filed: 1993-12-28
Abstract: PURPOSE:To provide a particle measuring apparatus which enables accurate measurement of scattered condition of particles scattered on a substrate. CONSTITUTION:An array substrate 15 is placed on the top surface of a substrate holding base with the surface thereof of spacer particles scattering upward. The top surface of the array substrate 15 is lighted from a ring illumination 56 through a light guide 57 and the reflected light is received by a CCD camera 50 through a zoom lens 55. A horizontal angle table 49 is turned with a horizontal angle handle 53 so that the regular reflection does not enter from a liquid crystal drive electrode of the array substrate 15 to adjust a horizontal angle and an arm 43 is turned with an elevation handle 44 to adjust the elevation theta2. Hence, the scattered condition of the spacer particles can be measured even when the array substrate 15 has no light transmitting property. This enables the setting of the CCD camera 50 and the ring illumination 56 to make an arbitrary angle therebetween and prevents the entry of the regularly reflected light into the CCD camera 50 from the array substrate 15 thereby enabling accurate determination of the scattered condition of the particles with the lowering of noises.
