Title: Sound recording bias oscillation circuit
Inventor: KUROOKA TAKASHI
IPC: G11B5/03
Filed: 1983-05-25
Abstract: PURPOSE:To obtain stable sound recording performance and erasure efficiency almost simultaneously with the start of sound recording by switching the secondary side of an oscillation coil through a transistor (TR) and turning on and off a bias oscillation circuit on AC basis, and performing switching between a sound recording on state and a sound recording off state. CONSTITUTION:The switching state of a switch 7 in the figure is the sound recording off state and a bias voltage is impressed to the base of the switch TR through a bias resistance R2. Therefore, the switch TR6 is on, so neither a sound recording bias current nor an erasure current flows to heads 1 and 2. Then, the switch 7 is operated to make contacts I and III, and then the switching TR6 becomes cut off. Therefore, the sound recording bias current and erasure current flow to the heads 1 and 2 to enter the sound recording on state. Thus, a bias oscillation circuit 3 is placed in an invariably active state on DC basis to supply the stable currents to the heads 1 and 2 almost simultaneously with the start of sound recording.

IPC: G01N21/59
Filed: 1987-04-17
Abstract: PURPOSE:To enable a rate measurement and an end-point measurement at a high accuracy without stopping the flow of sample, by making a first flow cell on a split optical path communicate with a second cell on the other split optical path using a specified length of passage. CONSTITUTION:An outlet 52 of a first flow cell 5 is connected to a changeover valve 53 while an inlet 61 of a second flow cell 6 to a changeover valve 54 and the changeover valves 53 and 54 interlock each other. An inlet 51 of the flow cell 5 communicates with a tube 22 while an outlet 62 of the flow cell 6 leads to a drain D. Moreover, one of a longer connection tube 7a and a shorter connection tube 7b maintained to a specified length is selected with the changeover valves 53 and 54. On the other hand, a monochromatic luminous flux 17 is divided with a sector mirror 41, for example, into two parts 26 and 27. The flow cells on respective optical paths communicates with one another and sample areas pass from one to another sequentially, thereby enabling measurement of hourly changes in the reaction of a sample.

Title: Majority decision coding/decoding system and encoder and decoder in the same system
Inventor: KAWABE MANABU
IPC: H04L1/08
Filed: 1989-04-14
Abstract: PURPOSE:To obtain a majority encoding/decoding system to be applied even for a line, where a burst error is generated, by transmitting the same data at prescribed bit intervals. CONSTITUTION:The data inputted from an input terminal 11 to an encoder are shifted for each step by respective shift registers 12-1-15-1 each time the data are inputted. Then, the data in the final step are inputted to a parallel/ serial converter 16. Since the inputted data are sent to an encoder output terminal 17 in the order of input terminals 16-5, 16-4,..., 16-1 in the parallel/serial converter 16, the same data are inputted to the parallel/serial converter 16 ever other(m) bit and outputted to an encoder output terminal 17 every other (5m+1)bit. Accordingly, the received data inputted every other fixed bit are inputted to a majority logic circuit at the same timing and error correction is executed according to majority logic. Thus, the majority encoding/decoding system can be obtained to be applied even for the line where the burst error is generated.
