Title: Encoder of chrominance signal
Inventor: WATANABE TOSHIAKI
IPC: H04N9/45
Filed: 1982-08-11
Abstract: PURPOSE:To form a chrominance signal with high accuracy and a small sized circuit, by giving a basic clock, a double clock and data to form the three primary colors to an ROM so as to form a conversion data and A/D-converting the data. CONSTITUTION:The basic clock fsc, a clock 2fsc and the designating data of the three pkrimary colors R, G, B are inputted to an address bus of the ROM21. The ROM21 leads out a parallel output data corresponding to each address data from its output terminal and inputs the data to a D/A converter 23. A chrominance component output is led out from the converter 23. The data required for the chrominance signal is written in the ROM21 in advance and each chrominance signal component is formed with the R, G, B data. Thus, since the ROM is used to form the chrominance signal from the three primary colors and the conversion data is outputted with digital processing, the chrominance signal is formed with high accuracy.

Title: High electric resistance aluminum alloy for cage rotor
Inventor: OGAWA KAZUHIKO
IPC: C22C21/00
Filed: 1975-11-18
Abstract: PURPOSE: To provide a high-resistance Al alloy for use as cage rotor not producing contract cracks at solidification by adding and alloying Al with specific amount of Mn, Cr, Ti, B, Fe, Si and Al.  
     CONSTITUTION: The object Al alloy contains Mn: 1.5W4%, Cr: 0.5W0.9%, Ti: 0.05W0.6%, B; 0.01W0.12%, Fe<0.3% and Si<0.3% or further Zr: 0.2W0.8%. An Al alloy, if contg. Mn>1.5% and Cr>0.5%, has properties desirable as low conductivity alloy for cage rotor, but it is likely to cause cracks due to solidification contraction at diecasting. Therefore, to this alloy, Ti and B are compounded and added so that above default is prevented and production yield in diecast is enhanced. Zr is effective in increasing fluidity of molten metal and in decreasing conductivity. Fe and Si are effective in controlling impurity to less than 0.3% and prevents conductivity increase and crack generation due to solidification contraction.

Abstract: PURPOSE:To reduce power consumption during disuse, to decrease a power voltage supplied from a switchboard, and to stabilize operation by inverting the polarity of a DC power source supplying electric power from the switchboard during calling operation and then by sending a call code signal. CONSTITUTION:When the handset of a digital telephone set is put off the hook while the digital telephone set is originating, a hook switch 3 is closed to form a DC loop including a switchboard, and once a power source circuit 5 rises, the switchboard detects the calling of the telephone set. During calling operation, the polarity of DC electric power supplied from the switchboard is inverted, and consequently a diode 7 conducts; and then a power source circuit 11 rises to close an electronic switch 4, thereby operating a digital telephone set circuit body 16 and a call signal detecting circuit 12. A call code signal is detected by a detecting circuit 12 and an electronic switch 14 is closed to drive a calling circuit 13, thereby calling a party subscriber. When the handset is put on the hook after a telephone call, the hook switch 13 is opened to reset the polarity of the DC electric power supplied from the switchboard.

Title: Exposure device
Inventor: TAKEDA SHOHEI
IPC: H04N5/238
Filed: 1988-06-07
Abstract: PURPOSE:To always control the exposure with high precision by comparing the exposure amount of a preliminary opening and closing action with a reference exposure amount, and transferring and recording to a recording circuit an exposure action or a value of a storing circuit according to a reference value derived from the repeated preliminary opening and closing, corresponding to the magnitude deviation. CONSTITUTION:In a first non-exposure opening and closing action, the detected value is stored once in the storing circuit, then the value is integrated to obtain the exposure amount, and next compared with the reference exposure amount. If there is a difference exceeding a set value, a second exposure opening and closing action is carried out taking into account the compensation derived from the value of the non-exposure opening and closing action, and when it remains within the set value, the value of the storing circuit is kept as it is, and recorded in a recording medium such as a floppy disk. Thus there is no more unnecessary taking over of photographs, and the exposure amount can be controlled with high precision, without generating any inconvenience in use.
