Title: Bucket for centrifugal pipe of centrifugal separator
Inventor: SHIRAISHI DAIJIROU
IPC: B04B5/02
Filed: 1979-03-30
Abstract: PURPOSE: To provide high strength to the bucket and let the same withstand high centrifugal force by forming the shape from the hook part of the large-diameter part of the bucket for the centrifugal pipe of the centrifugal separator up to its opening to the same diameter.  
     CONSTITUTION: The bucket 2 for this centrifugal pipe is worked in the order of the 1st drawing of (b), the 2nd drawing of (c) and the 3rd drawing of (d) as shown in the arrows from the round plate material 8 of (a). In the 3rd drawing, the opening end 11 is made the same outside diameter B of the outside diameter B after the 2nd drawing of (c) and the bottomed side of the other end is formed to the outside diameter A that can be fitted into the carrier of the centrifugal separator. Namely, the portion from the hook part 9 at the boundary of the portion of the outside diameter A and the portion of the outside diameter B up to the opening end 11 is formed to B of the same diameter. It is so formed that it is detained by the carrier at the hook part 9 and even if centrifugal force of high speed is applied, the large diameter part of the outside diameter B from the hook part 9 is formed thick and large in diameter and therefore considerably high strength is provided and even if high-spped centrifugal force is applied, the flying of the bucket 2 from the carrier is entirely eliminated.

Title: Drive circuit of charge injection device
Inventor: YOSHIDA YUKIHIRO
IPC: H04N5/335
Filed: 1984-02-29
Abstract: PURPOSE:To detect a line causing a fault by providing a current waveform detecting circuit in common among plural inverters and power supplies. CONSTITUTION:Inverters I1,I2-In consist of CMOSes and inputs Vinl-Vinn are received from a shift register 3. Thus, when a low level is given to the Vinl of the inverter I1, for example, a p-channel transistor (TR) Tp is turned on and an-channel TRTn is turned off, then a pulse current flow from a power supply VDD in the path of a resistor (r), the TRTp and a picture element CL1. On the other hand, in bringing the level of the input Vin3 of the inverter I3 to a low level similarly, a current flows from the VDD through the picture element CL3, but since a capacitor C and a resistor RL are connected in parallel equivalently, a DC flows through the resistor RL. Thus, in bringing the Vinl-Vinn to a low level sequentially, the voltage Vr across the resistor (r) becomes a pulse form waveform when the picture element is normal and if there is a fault, a DC component voltage is detected.

Title: Information input apparatus of digital circuits
Inventor: TANIGUCHI NOBUYUKI
IPC: G03B7/091
Filed: 1978-03-30
Abstract: PURPOSE: To provide the circuit constitution of less number of contact points by scanning the terminals selected by clocks and latching the count value of a counter which counts the clocks.  
     CONSTITUTION: As the respective terminals 0 1  thru 0 n  of a shift register 2 are scanned by the clocks from a clock signal generator 1, the sliding terminal a connected to the selected terminals 0 1  thru 0 n  generates a high level signal to latch a latch circuit 4. Hence, the count value corresponding to the selected terminal of a counter 3 which counts clocks is latched in the circuit 4 and becomes the digital exposure time signal, etc. of the camera. As a result, the digital information is formed without using any gray code plate or the like of plural bits provided with the contact points of the same number as bit number. This reduces the number of contact points of the information input unit and preventes the occurrence of error outputs.

Abstract: PROBLEM TO BE SOLVED: To reduce the noises propagated in a circulating stream and measure the small noises generated by a measured object by isolating the noises via reflection on an incidence end face and absorption in a mechanism. SOLUTION: This structure is constituted of multiple parallel plates 201 arranged at the prescribed intervals W, each parallel plate 201 is provided with a noise absorbing elastic member 212 acoustically softer than water such as rubber on the surface and back face of a core plate 211 such as an iron sheet, and the parallel plates 201 are fixed and reinforced with lateral plates 202. The sound waves propagated in flowing water are absorbed by the noise absorbing elastic members 212 if λ>2W, where λ is the wavelength of sound in the water and W is the interval between the parallel plates 201. When the interval W is set to 25cm, the sound waves with the cutoff frequency of 3kHz or below are absorbed by the noise absorbing elastic members 212.
