Title: Jam detector for copier
Inventor: ABE SHIYUNICHI
IPC: B65H7/06
Filed: 1978-05-22
Abstract: PURPOSE: To effect the jam detection with the use of a single timer, even when two sheets of copy paper exist in a conveyor passage, by starting the operations of the timer under the condition having only one sheet of the copy paper in the conveyor passage so that the operating time limit of the timer is set within a preset range.  
     CONSTITUTION: A first sheet of copy paper has its feed started at time t 1  and is discharged out of a copier at time t 2 , thus ending the copying operation. A next sheet of copy paper is fed at time t 3  before the time t 2  and is discharged at t 4  after the time t 2 . In case two or more sheets of copy paper exist in the conveyor passage, the signals at times t s1 , t s2  and so on the condition under which only one sheet of the copy paper exists in the passage are taken out to start the operations of the timer. The time limit of this timer is set more than the time, which is required for the copy paper corresponding to an obstacle to pass over the terminal end portion of the passage, and within a range until the timer starting signal generation corresponding to the accompanying copy paper. When the copy paper is not discharged within that time limit, the condition is detected as the jam of the copy paper.

Title: Drive circuit for dc motor
Inventor: UEMATSU EIJI
IPC: H02P7/288
Filed: 1981-04-22
Abstract: PURPOSE:To prevent the overcurrent damage of a switching element by stopping the supply of a voltage when the level of the current flowing through a series circuit of a DC motor and the switching element becomes higher than the prescibed value. CONSTITUTION:Transistors Q2-Q5 for driving a motor M are controlled by transistors Q1, Q6 which switches On or OFF in accordance with signals supplied to input terminals IN1, IN2. A resistor R9 for detecting a current is connected to the series circuit of the motor M and the transistors Q2-Q5. When an overcurrent flows through the motor M, a voltage across the resistor R9 rises, causing an SCR1 to be conducted ON. Accordingly, the transistor Q7 of a voltage supply circuit 2 is interrupted, thereby stopping the supply of a voltage. In this manner, the overcurrent damage of the transistors can be prevented.

Filed: 1982-04-14
Abstract: PURPOSE:To reduce the effect of a noise source at the middle of a system, by providing a circuit in a front stage of the noise source to rise the frequency characteristics of a high band higher than the flat characteristics and then another circuit at a rear stage of the noise source to lower said frequency characteristics down to the flat characteristics. CONSTITUTION:The signal of an image pickup tube 1 which passed through a preamplifier 2 is applied to a pre-emphasizing circuit 32 from a master gain switch circuit 31. The circuit 32 raises up the frequency of a high band of an input signal and then applies it to a contour compensator 4 via a variable gain circuit 33. The output of the compensator 4 changes the frequency of a high band to the original flat characteristics through a de-emphasizing circuit 34 and applies it to a gamma compensating circuit 35. The gamma-compensated signal is turned into a video output via a black clipping circuit 36 and an output circuit 37. This can reduce the effect of S/N deterioration which is due to the circuit 33 or a delay circuit 42 and turns into a noise source.

Title: Manufacture sealed lead-acid battery
Inventor: YOSHINAKA MINORU
IPC: H01M50/627
Filed: 1986-03-20
Abstract: PURPOSE:To quickly pour a prescribed amount of an electrolytic solution even if an exhaust port is made small, by putting a plurality of sealed lead-acid batteries in a hermetically sealable container, reducing the pressure in the container, and then supplying the electrolytic solution into the container to pour the solution into the batteries.

A valve A for the container 11 is then opened to reduce the pressure therein by a vacuum means 13. After that, the valve A is closed and another valve B is opened to supply an electrolytic solution from a tank 14 into the container 11. Since the pressure in the batteries 12 is also reduced, the electrolytic solution 15 supplied into the container 11 is quickly sucked into the batteries through exhaust ports. The electrolytic solution can thus be quickly poured into the batteries without overflowing through the exhaust ports, even if the exhaust ports are made small.

IPC: G06T7/00
Filed: 1990-03-13
Abstract: PURPOSE:To enable recognition of metal and a transparent object which could not yet be recognized with a TV camera by irradiating an object having a three-dimensional shape with an ultrasonic wave to accomplish identification of the object, estimation of a position and an angle of rotation and reproduction of an image from scattered waves thereof. CONSTITUTION:An object recognition equipment is made up of an ultrasonic transmitter 2, an A/D converter 3, an ultrasonic receiver 4 comprising an nXn receiver array and an amplification/noise elimination filter and a computer 5 to irradiate the object 1 with a burst wave from the transmitter 2. Then, a sound pressure of an ultrasonic wave measured with the receiver is sent to the computer 5 through the converter 3 to cut a waveform thereof in a time phase thereby obtaining information on the depth of the object. Then, an ordinary acoustic holography is used to obtain XY direction information, since the sound pressure measured cut can be considered as continuous sine wave in sections cut. Here, when the number of divisions in the depth-wise direction is (m), (n)X(n)X(m) pieces of information can be obtained.
