Title: Change-over circuit
Inventor: TAMAI HIDEFUMI
IPC: B60R16/02
Filed: 1985-04-17
Abstract: PURPOSE:To prevent erroneous operation of a change-over circuit which selectively supply power to two systems, in order to enhance the safety of the change-over circuit, by allowing the change-over of power between a main control device and an emergency control device when predetermined terms are satisfied. CONSTITUTION:When a power source switch 2 is closed, a power source 1 energizes a system A (main control device 9) through a contact A in a double throw switch 3 and a normally close contact 7a in a realy 7. At this time, if signals from condition sensors 4 such as a temperature sensor, a pressure sensor, a rotational speed sensor, etc. reach set values in a comparator 5, the latter issues an output to energize a relay 6 whose contact 6a is therefore closed. Thereby, a realy 8 is energizes so that a contact 8a is closed while a contact 8b is opened, and therefore, power supply to a system B (emergency control device 10) is stopped. Even if the double throw switch 3 is turned into the contact B side in this condition, the power supply to the system B is inhibited since the relay contact 8a is opened.

Title: Garbage treatment machine
Inventor: AOKI KAZUAKI
IPC: B02C17/16
Filed: 1995-04-07
Abstract: PURPOSE: To provide a garbage treatment machine not discharging a malodor and acidic air to the outside, efficiently drying and finely grinding garbage and detecting such a state that grinding treatment becomes impossible because a solid is caught in a grinding part to remove matter obstructing rotation. CONSTITUTION: An object to be treated is ground by stirring arms 8 and fixed arms 7 in a treatment tank 2 to be fermented under heating and dried to form compost which is, in turn, discharged to a compost stocker 3. Air in the treatment tank 2 is discharged to the outside through an exhaust passage in which a neutralizing and decodorizing device 4 is arranged. When a solid gets between the stirring arms and the fixed arms and the rotation of the stirring arms becomes impossible (the stirring arms are locked), the rotary direction of the stirring arms is reversed for a definite time by a lock self-releasing mechanism to remove the solid. When obstructing matter is removed (lock is self-released), the stirring arms are returned to normal operation to be rotated forwardly and reversely at every definite time.

Abstract: PURPOSE:To measure the line characteristic of transmission loss, etc., in both directions from one end part of an analogue line by selecting one among a reference signal outputted to the analogue line, a read signal and a signal outputted by means of a data station so as to output it to the analogue line. CONSTITUTION:When a maintainer operates the control panel 21-1 of a network test device 1-1 and inputs a test start command, a call control means 16-1 instructs a call means 10-1 of the connection of a telephone line and the transmission of a test start signal. An exchange network 50 transmits a call signal to a network test device 1-2 and sets the analogue line among the network test device 1-1, the exchange network 50 and the network test device 1-2. A switching means 18-1 selects the output of a signal generation means 12-1 and the signal generation means 12-1 generates the reference signal. The maintainer can obtain the transmission loss of the exchange network 50 by measuring the level of a measurement signal in a measurement unit 53-1.

Title: Detecting apparatus of attitude
Inventor: MATSUO CHIKAO
IPC: G01B11/26
Filed: 1984-04-24
Abstract: PURPOSE:To detect at high speed the attitude of an object to be detected by a simple process wherein a scan signal obtained by digitizing a picture signal of the object to be detected is compared with a scan signal of a standard object, either of the scan signals is shifted, and the number of shifting bits required until the two signals coincide with each other is calculated. CONSTITUTION:A standard object 30 is photographed, and the picture data thereof are stored in a picture memory 26. A picture processing device 27 finds the center 31 of gravity of the object 30 on the basis of the content of the storage, and performs scanning along a scanning route 32 traversing the contour of the image on a circle having the radius of a distance R from the center 31 of gravity, and thereby a scan signal is obtained. On the occasion, a scanning start point A is set beforehand. Next, as for an object 20 to be detected, scanning is also made along a scanning route 34 in the same sequence, with the center 33 and the radius R being set, and thereby a scan signal is obtained. On the occasion, a start point B is made identical with the start point A. Then, the two scan signals are compared with each other and shifting is made so that they coincide with each other. The angle of inclination of the obect to be detected is calculated simply from the number of bits required until the coincidence of the two signals are attained, and from the whole length of the scanning routes 32 and 34, and thus the attitude of the object to be detected in relation to the standard object can be detected at high speed.

Title: Production of porous separating membrane
Inventor: KARASAWA KICHIJI
IPC: B01D67/00
Filed: 1979-07-02
Abstract: PURPOSE:To shorten drying time and make the resulted dry membrane at least equal to or better than freeze-dried products by allowing the wet membrane to contact with an inert and water-soluble organic solvent to dehydrate and immersing the membrane in migratory liquid to substitute the solvent with the migratory liquid then drying it to a critical point. CONSTITUTION:In the production of a rewettable porous dry separating membrane of superior permeability performance, a membrane of acetyl cellulose or the like is used. The above-mentioned porous separating membrane having been wetted by being produced by a wet method is contacted with an inert and water-soluble organic solvent (e.g. acetone), by which it is dehydrated and the water is substituted with the solvent. It is then immersed in migratory liquid for performing drying to a critical point (e.g. liquefied carbon dioxide) and is left standing for 10- 30min to substitute the solvent with the migratory liquid. Next, it is dried by setting the temperature of the migratory liquid higher by 10-20 deg.C than the critical temperature and allowing the migratory liquid to evaporate gradually. As compared to a freeze-drying method, this method permits drying in a shorter time and nevertheless the dry membrane obtained is equivalent to that obtained by freeze drying and is much superior to that by an organic solvent substitution method.
