Title: Descramble system of catv terminal
Inventor: AMAMIYA YOSHIO
IPC: G06F21/10
Filed: 1983-10-31
Abstract: PURPOSE:To control freely sound volume by detecting a television RF signal which is scramble-modulated, by converting the signal to a base band signal, and by descramble-processing by the base band signal together with controlling sound quantity. CONSTITUTION:In a CATV terminal, a signal is coupled by loose coupling from a CATV-signal inputting terminal 1 to a data receiver 37. The data receiver 37 extracts and amplifies a terminal control carrier by a narrow-band filter. After amplification, AM detection or FM detection is executed. After detection, a waveform is shaped, and the carrier is supplied to a microcomputer circuit 38. The microcomputer circuit 38 decodes a code signal from a head end according to the decoding method which is determined beforehand, controls a scramble switch 32, and stops or sends to supply a regenerative scramble square wave signal to a multiplier 33. The circuit 38 also controls a reset terminal of a binary counter 19, and executes descramble processing by turning on/off an input signal of a pulse synthesizing circuit 20 and an input signal of a monostable multivibrator 25.

Filed: 1982-11-18
Abstract: PURPOSE:To adopt the switching signal producing method of a two-head VTR by determining a head switching timing based on a signal having three times the period of one rotation of a rotating body produced from a detecting pulse in synchronizing with the rotating phase of the rotating body. CONSTITUTION:The rotation detecting pulse synchronized with the rotating phase of the rotating body 1 fitted to four video heads A-D is extracted, a signal having three times the period of one rotating period of the rotating body 1 is produced from the detected pulse and the head switching timing at recording and reproduction is determined based on this signal. Thus, the recording/reproduction of an information signal such as the video signal is attained by using sequentially and cyclicly the four video heads A-D, and the track pattern compatible completely with the conventional two head VTR is recorded and the recording video signal is reproduced from a magnetic tape 2 without any hindrance recorded by the conventional two head VTR.

Title: Reproducing circuit for tape recorder
Inventor: OSAWA HIDEKI
IPC: G11B20/02
Filed: 1989-08-04
Abstract: PURPOSE:To prevent a read operation of unnecessary signal(s) and to repeatedly reproduce only necessary information by enabling the read commencing position of a signal stored in a memory circuit to be changed under a repeating operation state. CONSTITUTION:When signals A-K stored in the memory 13 are repeatedly outputted by a repeating operation, and when the signals A-E are not required, a read changing operation switch 20 is pressed to be closed at the end of reproducing the signal E. By this operation, the read commencing position of the signal stored in the memory circuit 13 is changed so that the repeating read from the signal F to the signal K is performed to sound a speaker 7. Then, under this state, when the switch 20 is turned on again, the state is restored to the original repeating operation state. Consequently, only necessary information is repeatedly reproduced, preventing the read-out of unnecessary signal(s).

Filed: 1982-11-19
Abstract: PURPOSE:To obtain a still picture transmitter which is utilized for mutual transmission and enables an instantaneous or sequential switching system by providing plural memories and switches on a transmission side. CONSTITUTION:A video signal inputted from a terminal 31 is A/D-converted and written in a memory 15 or 16 selectively through a switch 14, and one-field or one-frame contents are stored therein.

The switches 18 and 19 is operated to display a transmit picture and an already transmitted picture on the same television monitor all the time. Therefore, the switch 17 is changed over by transmission or reception to allow transmission control parts 20 and 30 to have bidirectivity, so that the television monitor a terminal 33 only displays a receive picture.

Title: Record player
Inventor: SUZUKI KIYOSHI
IPC: G11B17/04
Filed: 1981-12-16
Abstract: PURPOSE:To ensure a quick exchange of records, by giving a returning movement to a tone arm and at the same time drawing out quickly the main body of a driving part from a case regarless of an automatic play mode of a record player by the operation of an ejection switch. CONSTITUTION:An ejection switch 52 is closed when no exchange is required for the records in case the main body 1 of a driving part is set in a case 2 and a tone arm workng automtically, i.e., when a record stylus is not put on a record. Thus the potential of the connecting middle point P drops to feed the signal L to an NOR gate 55. At the same time, the input signal of an input terminal 59 is also set at L, and therefore the output of the gate 55 is set at H. Thus a flip- flop circuit 61 is driven to deliver a command signal to immediately draw out the main body 1. Accordingly a motor 21 is driven to move forward and backward a player board 9 to an inside housing. In accordance with the driving of the motor 21, a motor 22 is driven to drive the tone arm. Then the tone arm is returned.

Title: Touch panel
Inventor: YASUMURA MAKOTO
IPC: G06F3/03
Filed: 1988-08-18
Abstract: PURPOSE:To correctly detect the coordinates of a touch input point even though this point is set at an intermediate position between contact parts by securing the coincidence between the resistance value per unit length of each electrode line and the resistance value per unit length of a voltage dividing line. CONSTITUTION:The resistance value per unit length of each of electrode lines 25 and 26 is set equal to the resistance value per unit length of a voltage dividing line. As a result, the output voltage obtained when plural contact parts are turned on at one time is approximate to the intermediate value of each output voltage of contact parts S11 - 55 obtained when one of these contact parts is turned on even in the case of the constant current drive and the constant voltage drive. Thus it is possible to accurately know the coordinates of a touch input point even in the case this point is set at an intermediate position between the contact parts.
