Filed: 1983-03-24
Abstract: PURPOSE:To obtain an excellent binary-coded picture in high speed independently of the directivity of change in contrast of the picture by scanning full screen of a partial picture screen to adopt an average contrast value of the partial screen at each picture element as a threshold value of the picture element. CONSTITUTION:A video signal quantized by an A/D converter 1 is inputted to a segmenting section 2. A picture element selecting section 3 selects a picture element used for the operation of average contrast in a partial picture and an operating section 4 calculaten the average value. A video signal delay section 5 gives a delay to the video signal of the A/D converter 1. The average value being an output of the operating section 4 and an output of the delay section 5 are compared at a comparator section 6. Then, a binary-coded video signal is outputted from the comparator section 6.

Filed: 1983-03-28
Abstract: PURPOSE:To obtain sufficiently precise data without requiring skillfulness by measuring heat weight characteristics of silicone oil for electricity, finding a heat resistance index TGI from the characteristic curve, and deciding on deterioration when the index decreases below a specific value. CONSTITUTION:The heat weight characteristics of silicone oil for electricity which deteriorates are measured to obtain the curve as shown in a figure.

When the TGI of the silicone oil for electricity is calculated by using said equation, results in a table are obtained; when the silicone oil deteriorates, the TGI decreases and a decision on deterioration is made when the TGI decreases below 325. Therefore, sufficiently precise data is obtained without skillfulness.

Title: Digital signal recording and reproducing device
Inventor: KOSUGI TSUNEO
IPC: G10H1/00
Filed: 1989-03-02
Abstract: PURPOSE:To prevent sound control from becoming abnormal by inhibiting the transmission of a note-on message in the case that the bit thereof is not an initial value even when a note-on bit map is searched and the note-on message of an identical note number in an identical channel is reproduced in plural times. CONSTITUTION:When MIDI data reproduced by a demodulation means 9 is the note-on-message, the recording area of a memory able to read and write 10 where one bit is assigned to one note number is searched. When the prescribed bit of a prescribed address corresponding to the note-on message of the identical note number in the identical channel is not the initial value, the second and succeeding note-on messages are inhibited to be transmitted because the note number is already noted on. Thus, even in the case that one part of the MIDI data is omitted caused by the occurrence of an error which cannot be corrected or the like when the MIDI data is demodulated, a sound is prevented from being sounded on and various kinds of sound control are prevented from becoming abnormal.

Abstract: PURPOSE:To alleviate the power loss of a starting resistor by suppressing the voltage across the starting resistor to a low value at the normal time. CONSTITUTION:A voltage which is produced across a diode 14 is applied through a starting resistor 15 to between the bases and emitters of transistors 21, 22 at the time of starting an inverter circuit 20, and, after once started, the voltage across a condenser 31 forming a smoothing circuit is applied between the bases and the emitters of the transistors 21, 22 through bias resistors 27, 28.
