Title: Automatic sound image position controller
Inventor: KASUGA MASAO
IPC: H04S1/00
Filed: 1977-12-16
Abstract: PURPOSE:To automatically and accurately accomplish the control and indication of the movement  of a sound image to a fixed position by counting the clock, which are generated by a voltage control oscillator corresponding to the moving speed of the sound image, thereby to determine the  fixed position of the sound image in polar coordinates. CONSTITUTION:In response to the control signals corresponding to the moving speed of a sound  image selected, voltage control oscillators 14 and 15 generates clocks of a frequency corresponding  to the sound image moving speed. The resultant clocks are counted through gate circuits 6 and 7  by up- and down-counters 10 and 11, which are operative to effect the counting-up and -down  operations in response to the signals according to the moving direction of the sound image, so that  the counted values of the counters 10 and 11 becomes the digital values of the sound image moving angle and distance. As a result, if the acoustic signals to a rigth speaker are controlled in accordance with the counted values of the counters 10 and 11, the fixed position and moving  direction of the sound field are indicated. IF this indication is observed to close the gates of the circuits 6 and 7, the sound field can be automatically and accurately located in a desired position  at a desired speed and in a desired direction.

Title: Controlling circuit of video camera
Inventor: HIRATSUKA MASARU
IPC: H04N5/765
Filed: 1982-09-01
Abstract: PURPOSE:To raise operability of a video camera, by using an OR output of a signal for commanding a normal mode operation and a signal for commanding a fader mode operation, as a control signal. CONSTITUTION:A video camera is provided with a normal start/stop switch 2 and a fader start/stop switch 3. An OR output of command signals from the switch 2 and the switch 3 is outputted from a terminal 6 as an external control signal.

Title: Loop unrolling processing method
Inventor: AOKI MASAKI
IPC: G06F9/45
Filed: 1987-06-17
Abstract: PURPOSE:To decrease the program quantity and to improve executing efficiency by deciding the propriety for an unrolling action of a loop to produce a fraction processing program of the loop repeating frequency and performing a process where the loop is evolved into (n) times after the fraction processing. CONSTITUTION:An unrolling processing part 5 of a compiler 2 decides the propriety for an unrolling action in the processing of a single loop. When the unrolling action is carried out, a vector arithmetic train is produced only when a fraction exists in terms of the unrolling evolution number (n) when the repeating frequency is designated as a constant. If no constant is designated, an original loop is copied as it is and the repeating frequency set at a fraction is defined as a processing program of a fraction part in case a fraction exists. Then a program is produced for a loop evolved into (n) times and the remaining fraction part is processed. Thus the processing load of the compiler can be reduced and at the same time the quality of an object program is improved.
