Inventor: OOTA RIYOUZOU
IPC: B29C57/04
Filed: 1978-11-28
Abstract: PURPOSE: To form a fancet excellent in the inside shape and dimensional accuracy, by slidably fitting the segments of a split cylindrical metal mold whose diameter is reduced by displacing moving members back, on the tapered surfaces of the finger parts of the moving members.  
     CONSTITUTION: A hydraulic cylinder 11 is driven to displace a flange 9 on the rear end of the second moving member 5b back to an end plate 61 on a sleeve 6. The second metal mold segment 12b falls toward the axis of a support bar 1 due to the backward displacement of the second moving member 5b. When the fall has ended, the projection m of the second metal mold segment 12b is located inside the diameter of a fancet W shown by a dotted line. A piston rod 8 is thereafter retracted by a hydraulic cylinder so that the finger part 52b of the second moving member 5b and the finger part 52a of the first moving member 5a are simultaneously displaced back.

IPC: H03M1/66
Filed: 1980-10-22
Abstract: PURPOSE:To convert an input digital signal to a smooth analogue waveform without break points in a high speed, by utilizing the probability stastical processing. CONSTITUTION:A spurious random pulse signal (x) of the same number of bits (N-number bits) as a digital signal inputted to a D-A converter is generated at an output period tau by a spurious random signal generator 2, and an amplitude probability density function P(x) of the pulse signal (x) is made constant. This pulse signal (x) is latched in a latch circuit 3 at every tau and is applied to a digital comparator 1 surely in every pulse. The comparator 1 compares the pulse signal (x) and a sample value f(iTs), which is obtained by sampling an input digital signal f(t) at a sample period Ts(>>tau), with each other for every bit, and outputs a high- level signal under the condition of x<f(iTs). This output signal is converted to an analogue signal corresponding to the input digital through a filter 4 consisting of an integrating circuit.

Title: Apparatus for inspecting clogging of through hole
Inventor: KITAKADO RYUJI
IPC: G06T7/00
Filed: 1992-05-15
Abstract: PURPOSE:To make a delicate decision as to whether a through-hole is opened enough not to hinder the insertion of a part. CONSTITUTION:By the action of an image reading device 200, an extension circuit 300, an OR circuit 101 and a logic circuit 103, a differential image signal DIFS representing clogging of a through-hole by burrs or the like is obtained. An operator OP of the predetermined size is allowed to act on the differential image signal DIFS by a two-dimensional shift register 400 and an operator circuit 500. When an area (image area EI) where the differential image signal DIFS shows a value '1' includes the operator OP, the through-hole is determined to be defective with respect to clogging. Since the operator is used as a reference and the through-hole having the larger clogging than the operator is determined to be a failure, a delicate determination becomes possible.
