Title: Jam detector of copying machine
Inventor: HIRAIKE SHIZUKA
IPC: B65H7/06
Filed: 1981-02-24
Abstract: PURPOSE:To detect the jam at the position of the 2nd detector, by measuring the time during which the tip of the copy paper arrives and the rear edge of the paper passes and detecting by the 2nd detector that the rear edge of the copy paper does not pass even in the lapse of the above-mentioned time of measurement after the tip of the paper arrives at the 2nd detector. CONSTITUTION:The counting starts when the copy paper 12 reaches the 1st detector 14 and then stops when the rear edge of the paper 12 passes through the detector 14. When the tip of the paper 12 reaches a transfer part detector 15, the subtraction starts from the value of time which is previously counted. Then the jam is decided if the pass of the paper rear edge is not detected although the count value becomes zero. Thus the operation is discontinued for the peripheral devices of a photoreceptor 19 as well as for the feed of the paper 12. In the same way, the operation of a fixing device 16 is discontinued when the jam is detected to a fixing part detector 17.

Filed: 1997-02-12
Abstract: PROBLEM TO BE SOLVED: To suppress crystal defects by using a system equipped with a growing room where the source gas of group III elements and the source gas of group V elements are separately supplied to a substrate and a compd. semiconductor layer is grown on the substrate, and by irradiating the substrate with UV rays in the region where the group III source gas is supplied. SOLUTION: A substrate 8 is placed on a substrate holding face 10 of a substrate holder 9 and the substrate is heated at 400 to 550 deg.C as held. The group III source gas such as trimethylgallium and the group V source gas such as arsine are supplied through source gas supply ports 2, 3 for group III and group V elements, respectively, to the inside of a cylindrical part 1a. The region where the group III source gas is supplied is repeatedly irradiated with light from an ALF excimer laser. The group III and group V source gases and hydrogen gas for acceleration are supplied in each specified flow amt.  The substrate holder 9 is rotated around the center line of the cylindrical part 1a so that the group III source gas and the group V source gas are alternately supplied, while the region where the group III source gas is supplied is irradiated with UV rays 105 to activate the substrate surface. Thus, migration of the group III elements is accelerated to grow single atom layers of a compd. semiconductor such as GaAs.

Title: Filter
Inventor: SHIOZAWA YOSHIHIRO
IPC: G21C19/30
Filed: 1983-02-23
Abstract: PURPOSE:To control easily the supply of feed liquid to be treated to each filter by providing a pipe loss generating device to branch pipes connecting plural filters having different liquid passing times which are installed in parallel between an inlet header and an outlet header with each of above-mentioned header. CONSTITUTION:A flowmeter 14, an inlet valve 16 and an orifice 56 for generating pipe loss are provided to an inlet branch pipe 12 for introducing the feed liquid to be treated flowing in an inlet header 10 into filters 20A, 20B...20N. The operating condition of each filter 20A, 20B...20N is inspected by detecting the differential pressure of each filter obtained from a differential pressure gage 34. Since the feed liquid to be treated passes through the orifice 56 in the flow of each series, the differential pressure caused by piping, valves and orifices is increased as compared with before and the differential pressure in each filter is relatively decreased. In this way, the flow rate to each filter can easily be controlled.

Abstract: PROBLEM TO BE SOLVED: To obtain a detecting apparatus which can correctly detect an abnormality of a temperature change of outer walls of facilities such as a power- generating plant and the like. SOLUTION: An infrared image by a temperature of a facility outside wall is taken by an infrared camera 1 into an image-processing apparatus (step A2). A characteristic point of the taken image is calculated (step A4). A characteristic point of a reference image taken beforehand is calculated (step A6). After characteristic points of both images are registered (step A7), a subtraction between the taken image and reference image is carried out (step A8). A temperature abnormality of the facility outside wall is compared on the basis of the reduction value (step A9). Accordingly, shaking of the infrared camera can be corrected and a correct temperature can be detected.
