Title: Data line loopback test method
Inventor: OKITA RYOJI
IPC: H04L69/40
Filed: 1984-07-17
Abstract: PURPOSE:To attain automatic loopback test even between MODEMs having different communication speeds by providing a speed change means changing the speed of input data into a prescribed speed and discriminating the input data into a modulator-demodulator. CONSTITUTION:In case of a V.27 type MODEM3, a multiplier circuit 11 is added and a frequency division circuit 12 of frequency dividing ratio 3/16 is provided. When a loopback command (2) is inputted to a MODEM transmission/reception circuit 6'' from a MODEM (V.29 type), a baud rate signal (4) of 1,600 Bauds is multiplied three times at once by the multiplier circuit 11, frequency-divided in the frequency dividing ratio of 3/16 at the frequency division circuit 12 and a signal (5) having a communication speed of 300bps is outputted to a data discrimination circuit 8. On the other hand, a loopback command (2') having a communication speed of 300bps is fetched to a data discriminating circuit 8'' from an output of the MODEM transmission/reception circuit 6'' and a data discrimination circuit 8'' discriminates it that the loopback command (2') data is a loopback command at the MODEM3 from the input of the same communication speed to start a loopback control circuit 7''.

IPC: G06F3/03
Filed: 1999-05-27
Abstract: PROBLEM TO BE SOLVED: To attain the accurate ON detection by starting first the voltage with no intervention of the ON detection resistance in an ON drive mode to start a sheet of the drive side in a short time and also to sufficiently drop the voltage in a sense mode after the ON detection. SOLUTION: An electrode yH of the high side of a host electrode is connected to +5 V via a transistor TryH, an electrode yL of the low side of the host electrode is connected to 0 V via a transistor TryL and the electrode yH is also connected to +5 V via the ON detection resistance R and a transistor TrSW. Then the transistors TryH and TrxL are turned on to start the voltage. The voltage is quickly started since the TryH is connected to +5 V with no intervention of the resistance. Then the TrSW and TryH are turned on and off respectively. Under such conditions, the voltage is started by the TryH and accordingly no delay is caused. Then a sense terminal is turned on to sense the voltage and the ON detection is carried out.

Title: Reproducing device for data recording disk
Inventor: WATANABE KAORU
IPC: G11B17/051
Filed: 1988-06-16
Abstract: PURPOSE:To realize the common use of disks having different outer diameters by securing the common use between a drive source for reciprocating motions of a pickup unit and a drive source for front-back movements of a disk positioning member respectively. CONSTITUTION:A pickup unit has the reciprocating motions at reproduction and therefore a drive source 51 does not work in other periods of time. Thus the disk positioning members 26-28 are moved back and forth by the source 51 in said idle periods of time. The members 26-28 are usually moved back. Thus a loaded disk of a large diameter is guided with the members 26-28 kept at their retreated positions and then loaded at a reproduction positions. While a disk of a small diameter is loaded. In this case, the source 51 works to move forward the members 26-28 and the disk is guided by the members 26-28 to be loaded at the reproduction position, i.e., the same rotational center. Thus a loaded disk of a large or small diameter can be position. Then it is possible to obtain a reproducing device that can be used in common to the disks of different outer diameters.

IPC: F04C29/00
Filed: 1984-07-17
Abstract: PURPOSE:To correct unbalance in the centrifugal force applied to a crank shaft by allowing a non-compressive liquid to stagnate in the space formed between the periphery of an aux. member, which is loose fitted in a through hole in a rotor and stretched over the crank shaft, and the interior wall of rotor on the opposite side to the center of gravity. CONSTITUTION:A gap S is formed between a side plate 27a of an aux. member 27, which is stretched over a pair of crank shafts 17 while taking a condition as loosely fitted in a through hole 35 provided in a rotor 33, and its interior wall 35a on the opposite side to the center of gravity. Because a non-compressive liquid as lubricant is stagnating in this gap, rotation of the rotor gives a rise of hydroplane phenomenon between the interior wall of the rotor and the side plate of said aux. member 27, and thereby such a pressure is generated as to correct the unbalance in the centrifugal force applied to the crank shaft.

Abstract: PURPOSE:To form a multiwipe effect with a simple constitution by writing a TV video signal in the memory of the capacity of a horizontal scanning period width by a linear address and reading it with a modified address to a required degree. CONSTITUTION:The memory for storing the 1H of the TV video signal is written by the linear address outputted from a main address generator 5 cleared by a clear pulse from a terminal 2 for every 1H.
