Title: Ultrasonic sensor
Inventor: TOYODA JUNICHI
IPC: G01B17/00
Filed: 1998-07-16
Abstract: PROBLEM TO BE SOLVED: To provide an ultrasonic sensor capable of spreading detection region by adding a negative capacitance circuit, suppressing the oscillation due to the addition of the negative capacitance circuit and increasing the detection voltage. SOLUTION: When the ratio of the resistance 30 and the resistance 32 of negative capacitance circuit 18 is let N, the amplification degree observed from the nonreversible input terminal of an operation amplifier becomes N+1. Thus, after the voltage between both ends of piezoelectric oscillator 16 is multiplied N+1 time, it is normally fed back to the piezoelectric oscillator 16 through a capacitor 26. As a result, a current corresponding to the loss current flowing through damping capacitance Cd is supplied through the capacitor 26, the damping capacitance Cd is cancelled and the output voltage of an ultrasonic sensor 14 improves.  Also by the resistance 40 inserted between the output terminal of the operation amplifier 20 and the capacitor 26, the oscillation condition of the Wien bridge oscillation circuit constituted of an ultrasonic sensor 14 and a negative capacitance circuit 18 can be shifted. Therefore, the capacitance of the capacitor 26 can be increased and the output voltage of the ultrasonic sensor 14 can be improved. Thus, the reception sensitivity of the ultrasonic sensor 14 can be improved.

Title: Interphone set
Inventor: MATSUDA MITSUHIRO
IPC: H04B3/20
Filed: 1986-08-29
Abstract: PURPOSE:To improve talking quality by inserting a variable frequency filter to one transmission line so as to prevent suitably the effect of an unpleasant side tone. CONSTITUTION:A sound outputted from a speaker 9 of a handset unit 2 is inputted to a microphone 7 of the same unit 2 and fed back to a receiver 5 of a unit 1 to give a possibility of causing an unpleasant side tone. In this case, a filter 12 is inserted in a talking circuit reaching the receiver 5 of the unit 1 and since the high frequency attenuation of the filter 12 is larger as the signal level on the line 11 is larger, then the effect of the side tone due to acoustic coupling from the speaker 9 of the unit 2 to the microphone 7 is very small.

Title: Production and storage method of check data
Inventor: AIHARA MASAYOSHI
IPC: G06F12/16
Filed: 1984-09-28
Abstract: PURPOSE:To facilitate an easy change of the check data due to a data change by producing the check data from the data on an ROM through a prescribed calculation, and storing the check data to a memory means different from the ROM. CONSTITUTION:A control part 1 reads data out of an ROM2 and adds them to the contents of a buffer register. When all data are read out of the ROM2 together with addition of values of these data, the contents of the buffer register, i.e., the check data are stored in a memory means 4. When this storage is over, the working of the part 1 is rest to an original main routine for execution of a prescribed function. Thus the total value of the data stored in the ROM2 is obtained when necessary, and compared with the check stored in the means 4. Thus it is possible to check whether the contents of the data in the ROM2 are changed or not.

Abstract: PROBLEM TO BE SOLVED: To detect a remaining amount of paper at various steps by a large quantity paper supply unit when power supply of an image formation device is turned on and a paper supply cassette is set again. SOLUTION: This image formation device is provided with a bottom plate detection switch 4 detecting whether a bottom plate 1 in a paper supply cassette is between a lower limit position and an upper limit position or not. When it is detected that power supply of a device main body is turned on, the paper supply cassette is set again, and the bottom plate 1 is at a predetermined position by the bottom plate detection switch 4, the bottom plate 1 is lifted while detecting a remaining amount of paper 3. When the bottom plate detection switch 4 is not turned off during lifting and an uppermost surface of the paper 3 is detected by a paper surface detection sensor 6, lifting of the bottom plate 1 is stopped, and operation moves to a printing wait condition and printing operation.  If the bottom plate detection switch 4 is turned off during printing, the number of supply papers is counted per supply of paper. When the count value reaches the value set in advance, a remaining amount of the papers is estimated. The remaining amount of the papers is detected at many steps by preparing several kinds of set values.

Inventor: OTANI TATSUO
IPC: B05C15/00
Filed: 1994-08-04
Abstract: PURPOSE:To easily clean a booth for continuous powder coating to change colors in a short time without worsening the working environment by manual operation or an automatic device, by cleaning the inner surface of the booth to change colors with a cleaner by manual operation or by an automatic cleaning device while the booth is rotated. CONSTITUTION:A tube 16 is connected to a handle of a cleaner 15 and the tube 16 is taken out outside the booth and connected to a vacuum filter or a powder separating device installed in a factory. While rotation of the booth is temporarily stopped, the region (h) on the inner wall of the booth where an operator in the booth can most easily work is cleaned. The operator moves in the horizontal direction in the region (h) and cleans the booth in the horizontal direction. After this process is completed, the booth is slowly rotated so that the upper area not cleaned is lowered. When the area not cleaned is in the position of the region (h), the booth is stopped and cleaned again in the horizontal direction. This operation is repeated to wholly clean the inner wall of the booth.

Abstract: PROBLEM TO BE SOLVED: To generate a maximum torque corresponding to the magnetomotive force by inclining the radially outer end face of tooth such that the gap, between the tooth and a field pole, is spread forward in the rotational direction by an angle corresponding to the flux density in the gap. SOLUTION: A plurality of teeth 9 are provided on the outer circumference of an armature 3 and an armature winding 4 is set in a slot 10 made between adjacent teeth 9, 9. A pair of flanges 11a, 11b are extended, in the rotational direction, from the radially outer end face of each tooth 9 inclining linearly such that the gap 5 is spread forward in the rotational direction. Consequently, the component in the rotational direction of flux acting on the end face of each tooth 9 is increased thus generating a sufficiently large torque. Furthermore, since the inclination angle of end face of each tooth 9 is set at a value corresponding to the flux density in the gap 5, a maximum torque corresponding to the magnetomotive force of motor can be generated.

Abstract: PROBLEM TO BE SOLVED: To simplify the constitution of a circuit by detecting both of reduced voltage and excess voltage of each of plural DC power supplies (hereinafter referred to as +B power supplies) having respectively different voltage levels by one switching circuit. SOLUTION: When the voltage of any one of plural +B power supplies 1 is dropped to a low voltage, diodes 4, 5 connected to the +B power supply 1 are turned on and a transistor(TR) 3 is turned on, so that the output 12 is turned to high voltage. When the voltage of any one of the +B power supplies 1 exceeds required voltage, the emitter voltage of the TR 3 is boosted, so that the TR 3 is turned on and the output 12 is turned to high voltage. Since the reduced voltage state and excess voltage state of any one of the +B power supplies l can be detected by one switching circuit, the constitution of the circuit can be simplified.
