Title: System for measuring response time of analog signal circuit
Inventor: NISHIMURA TAKASHI
IPC: H04B17/00
Filed: 1982-02-18
Abstract: PURPOSE:To automate the measurement of response time, by detecting the peak point of the output waveform of an analog circuit, digitizing the detected signal through AD conversion, and then, calculating the response time of the analog circuit with the digital signal. CONSTITUTION:A control circuit, upon reception of a start signal (a), is set to the waiting condition and waits for an output signal (c) of a circuit 3 to be measured. When the signal (c) exceeds a level, the control circuit outputs a measurement starting instruction to the whole measuring section 4a and, at the same time, a start signal (k) to a computer 11, respectively. Then, a zero-cross detecting circuit 7 performs polarity discrimination on the waveform of the signal (c) and outputs a signal (f) or (g) by moving a pulse peak holding the circuit 5 or minus peak holding circuit 6 corresponding to a control signal (d) or (e), and simultaneously outputs an instruction (j). Upon reception of the instruction (j), an AD converting circuit 10 converts a peak holding value (h) and sends a lead timing signal (l) necessary for the calculating of respnse time and a converted deata signal (m) to the computer 11.

Title: Compression molding machine
Inventor: TAKEI TERUO
IPC: B28B3/02
Filed: 1981-02-25
Abstract: PURPOSE:To obtain a homogeneous product in a short time by a simple constitution, by simultaneously pressing a material supplied in a molding box, from both the upper and lower surfaces. CONSTITUTION:A material 2 is supplied into a molding box 1 from a material supply box, and it is pressed simultaneously by upper and lower pressure legs 3, 4. In this case, upper and lower pressing powers collide with each other in the center part of the molding box 1, and operate on a peripheral unpressed part 5 whose pressure has been dropped due to friction of the inside surface of the molding box. A moving distance of the upper and lower pressure lengs becomes half comparing with the one-surface pressure system, therefore, the pressure time is reduced to half, and also a homogeneous product is obtained owing to the proper pressure required.

Abstract: PURPOSE:To improve the efficiency of a picture processing by setting the most significant order bit of a picture memory to the identification code of the presence or absence of a picture element and using a low-order bit as an area storing a label value. CONSTITUTION:Data stored in the picture memory of 16 bits is binarized and stored in the most significant order bit as binarization information, for example. Next, a point where the most significant order bit shows one ('picture element -1') is searched from the upper left of a screen by raster scan, and the initially detected one is stored as PIS. Scan is executed from the point to a right direction until 'picture element -1' is eliminated, and the most significant order bit is changed to '0', whereby '1' is filled in the low-order bit as a label. Next, the presence or absence of continuous 'picture element -1' is checked with respect to a preceding and subsequent line, and a similar operation is executed if any. When the continuous picture element is eliminated, the operation is tried again from beginning. '2' is used for the label at that time. Thus, the operation is repeated until 'picture element -1' is eliminated.
