IPC: B60J1/17
Filed: 1997-10-21
Abstract: PROBLEM TO BE SOLVED: To facilitate the escape of a driver by providing a submerged sensor, a melting fuse and the like in the control circuit of a window opening/closing motor, and not rotating the window opening/closing motor to a closing side, even if a vehicle submerges and leak current occurs. SOLUTION: When a vehicle falls into water by an accident, current flows in a submerged sensor 6, the fuse 7a of a prohibition part 7 is fused by the current to cut a connection path between the coil 4a of a closing relay and a direct current power source 13. Even if a transistor 4i flows into a base and operation is switched on by leak current, excitation current is prevented from flowing into the coil 4a of the closing relay. Thus, even if a control circuit 4 is submerged and malfunction is performed, a motor 1 is not driven falsely to the closing side. In the prohibition part 7, a coil, a relay, a switch and the like in addition to the fuse may be used. Thereby even if the vehicles submerges, malfunction is prevented, and the life of the drivers can be protected.

Title: Bottle management method for granular chemical of granular chemicals dissolving device
Inventor: ICHIKAWA SHINICHI
IPC: B01F15/02
Filed: 1996-11-15
Abstract: PROBLEM TO BE SOLVED: To surely recognize the time for changing bottles and to improve working efficiency. SOLUTION: The management of the bottles is executed by indicating the state that the bottles are loaded into loading ports in unsealed state by lighting of pilot lamps 148. The state after the bottles are unsealed before a stirring treatment ends is indicated by flickering of these lamps. The state that the stirring treatment ends and that the bottles are empty is indicated by the putting off of the lamps. When the bottles are moved during the lighting or flickering of the pilot lamps 148, a reset is expected for three seconds after the checking of the bottles with the bottle check sensors described above is no longer possible so that the prompt execution of cancellation is averted. As a result, the treatment is continued and the useless consumption of the granular chemicals, etc., is obviated even in case an operator inadvertently touches the bottles.

IPC: G01L11/00
Filed: 1996-10-31
Abstract: PROBLEM TO BE SOLVED: To accurately judge the presence or absence of empty can leakage by a method wherein a gas is introduced into empty cans to be detected, and such a point that the pressure in empty cans is dropped more than a peak value and is mitigated is set as start point, and the change of the pressure of empty cans is measured and a pressure dropping ratio for measurement time is found.

When vapor 61 such as pressurized air is introduced from a vapor passage 6 into the empty can, an inner pressure of the empty can is elevated instantaneously and reaches a peak value, and thereafter the inner pressure is gradually dropped according to uniformity thereof, and a ratio of dropping is mitigated to be in a steady state.  Then, this time is set as a measurement start point, and the inner pressure of the empty can is detected temporally by a pressure detection sensor 7 communicating with a tip of a branch passage 63, and it is decided whether or not the empty cans exist from a tendency of pressure change. Thereby, it is possible to accurately and readily judge in a short time.

Filed: 1986-12-23
Abstract: PURPOSE:To speed up an access time by comparing the contents of a first register with the second register, and selecting the output of a block red buffer when they coincide with each other. CONSTITUTION:A read address from a CPU 200 is set in a first register 3 by a read start signal (b).

Title: Input circuit
Inventor: MURAO FUMIHIDE
IPC: H03F3/343
Filed: 1991-10-24
Abstract: PURPOSE:To make the current of an input and an output constant independently of an input voltage by connecting a 2nd resistor between emitters of two transistors(TRs) and other terminal of a series connection body of diodes, connecting one collector of the two TRs to an input terminal and using the other collector of the two TRs as the output. CONSTITUTION:With an input voltage VIN applied to an input terminal 1, a current flows through a resistor 3 to diodes 4, 5, bases of TRs 6, 8 have a voltage equal to twice the forward voltage VF of the diodes 4, 5, currents IC6, IC8 flowing to the TRs 6, 8 are constant because the forward voltage VF of the diodes and a base-emitter voltage VBE of the TRs are less dependent on the flowing current. Thus, the relation of an input current IIN=IC6 and of an output current IOUT=IC8 is in existence by selecting a current flowing to the diodes 4, 5 to be sufficiently small and selecting the resistance of the resistor R3 to be large and both the input current and the output current are constant. Thus, the input circuit with less dispersion in the current with a small resistance is obtained.
