Title: Josephson pulse generating circuit
Inventor: KOTANI MASATAKE
IPC: H03K3/38
Filed: 1984-05-31
Abstract: PURPOSE:To generate an efficient pulse signal which has its DC component removed while maintaining steep rising and falling characteristics by connecting a series circuit of an inductance and a resistance in parallel to Josephson junction. CONSTITUTION:The current flowing through the Josephson junction 20 does not flow through an inductance 21 abruptly because of the presence of the inductance, so the major part of the current flows through the Josephson junction 20 in the beginning, so the bias current has a steep rising characteristic. Then, no constant DC current flows after the bias current flowing through the Josephson junction 20 falls, thereby obtaining a steep falling characteristics. Therefore, the series circuit has a high impedance characteristics to the rising of the pulse current of the Josephson junction 20, i.e. high frequencies, and this characteristic is utilized to generate a pulse signal which has steep rising and falling characteristics.

Title: Working machine apparatus
Inventor: IBUKI TOSHIO
IPC: E02F3/76
Filed: 1988-05-10
Abstract: PURPOSE:To prevent a blade from falling ahead by engaging the right and left end portions of a plate adapted to support a blade of an angle tilt dozer in such a manner as to freely move horizontally and longitudinally with a groove provided on the back of the blade parallel to the blade. CONSTITUTION:In a working machine apparatus adapted to conduct angle and tilt operation by an angle cylinder 24 and a tilt cylinder 29, a blade 14 is supported through a plate 17 adapted to tilt in the horizontal and longitudinal directions. A pair of guide portions 18, 18' are fixed to the back of the blade 14, and both end portions of the plate 17 are engaged with a guide groove 19 formed in the vertical direction between the guide portions 18, 18' and the blade 14. By this arrangement, even if oil spillage is caused in the angle cylinder 24 to cause the blade 14 to fall ahead, the guide portion 18 is engaged with the plate 17 to prevent such falling ahead.

Title: Ink jet recording device
Inventor: TSUYUKUBO SHIGERU
IPC: B41J2/175
Filed: 1988-05-10
Abstract: PURPOSE:To prevent faulty ink discharge due to ink fluidity by providing a fluidity inhibitive member which makes possible the control of flowing ink at least at one end of an ink supply tube. CONSTITUTION:An ink liquidity inhibitive member 21 is filled in uniform density, in a section from a tube post 9 with crossing lines provided in a lattice form to a point near a carriage 6 of an ink supply tube 12. During ordinary recording or a recovery action, the amount of ink supplied to a recording head 5 from an auxiliary ink tank is small, so that a sharp pressure variation does not occur in the auxiliary ink tank 8. Therefore, it is possible to make up the ink 18 slowly in the auxiliary ink tank 8, if the ink liquidity inhibitive member 21 were loaded in the ink supply tube 12. Furthermore, the sudden movement of the ink due to its inertial force following the shift of the carriage 6 is controlled by friction resistance between the ink and the member 21. Consequently, the backflow of the ink 18 from the tube 12 to the auxiliary ink tank 8 is prevented and thereby a normal ink discharge can be ensured.

Title: Position detection device
Inventor: MURAKAMI AZUMA
IPC: G06F3/048
Filed: 1989-05-01
Abstract: PURPOSE:To prevent self working environment from being disturbed by means of others even if there is only one computer by providing different codes for plural position instruction devices and operating the computer in accordance with the position instruction device to be used. CONSTITUTION:When the switch 91 of an input pen is turned on, the phase of the current of a resonance frequency in a tuning circuit incorporated in the pen is delayed by a prescribed angle with respect to the phase of a voltage. Consequently, the phase of a reception signal is delayed by the prescribed angle with respect to the phase of an input signal. When a processor detects the phase difference, on/off of the switch 91 can be detected. On/off of the switch 91 outputs an eight bit signal outputting the values of respective bits by the pulse width of an output signal from a code generation circuit 95. When the signal is '1', the switch 91 is turned on and the reception signal in which the phase difference occurs is syncrhonized with an eight bit code so as to be outputted. Consequently, a self work can be continued without disturbing the working environment of the others, provided the eight bit code is decided at every input pen.

Abstract: PURPOSE:To superimpose communication identifying code easily without reducing information amount at a data communication not having a frame synchronizing signal, by primary modulation with virtual noise code such as PN code and gold code  to a transmission data. CONSTITUTION:A transmission data signal from an input terminal 11 is code- converted with an output of a virtual noise code generating circuit 13 at an exclusive logical sum circuit 12 and transmitted to a reception circuit 16 from a transmission circuit 14 to a transmission line 15.
