Title: Controller of upper part swiveling body in hydraulic excavator
Inventor: MORIYA YUKIO
IPC: E02F9/22
Filed: 1989-02-28
Abstract: PURPOSE:To promote swiveling control efficiency by providing a pressure controlling valve to be controlled by a proportional electromagnetic valve and a controller in a hydraulic controlling circuit, and controlling inlet pressure and outlet pressure of a driving motor. CONSTITUTION:When an upper part swiveling body driving motor 3 is accelerated at the time of right directional swiveling, an accelerating signal equivalent to a swiveling speed of the driving motor 3 is outputted to a solenoid A for a proportional electromagnetic valve 8 of a meter-in-poppet valve 2 from a controller 7. After that, a signal to become set pressure corresponding to an open signal of the poppet valve is outputted to a pressure control valve 10. In case the driving motor 3 is decelerated, a deceleration signal is outputted to the solenoid A for a proportional electromagnetic valve 8a of a meter-out-poppet valve 9 from the controller 7. In addition, a signal to produce set pressure corresponding to the open signal of the poppet valve is outputted to the solenoid of a pressure control valve 11. Driving pressure of damping pressure of the upper swiveling body is controlled according to acceleration or decelerated amount. According to this constitution, rapid pressure boosting is prevented, and shock of a hydraulic excavator can be reduced.

Title: Control method for memory device
Inventor: TAMAKI ISAO
IPC: G06F12/14
Filed: 1990-02-27
Abstract: PURPOSE:To select data to be loaded from the first memory to the second memory for the unit of a prescribed data area corresponding to the kind of the data by varying key operations corresponding to the degree of importance for the data. CONSTITUTION:Only the contents of a prescribed part in a second memory 2 are replaced based on the contents of a first memory 1 by the first key operation. By the second key operation mode complicated that the first key operation, the contents excepting for the prescribed part in the second memory 2 at least are replaced based on the contents of the first memory 1. Namely, the important data not to be changed unless there is any special cause after being once set can be replaced only by the second key operation rather than the first key operation. Thus, it is not necessary to load the default data of a ROM to the other memory each time a power source is turned on to a set, and the data to be loaded to the memory can be selected for the unit of the prescribed data area corresponding to the degree of importance and the kind of the data.

Title: Scramble system of charged television broadcast
Inventor: SHIOYA SHIGEYUKI
IPC: H04N7/167
Filed: 1984-03-14
Abstract: PURPOSE:To attain simple descrambling and to offer difficulty against interception by inverting the white/black level of a video signal only in a predetermined order at each video period, changing the order at each field or plural fields and inserting the changing information in the vertical blanking period. CONSTITUTION:The white/black level of the video signal is inverted in a predetermined random order at each horizontal period as shown in Fig. (b) as the scrambling method. No processing is applied to the horizontal synchronizing signal and the vertical synchronizing signal. Then the order of the white/black level inversion of the video signl at each horizontal period is conducted at random order different at each frame. The scrambled video signal is inverted for the white/black level at a white/black inversion SW6 by using a timing pulse and vonverted into the descrambled video signal. The timing pulse is reproduced from a data written in a microprocessor in advance by allowing the data of the vertical blanking period of the scrambled video signal to be decoded by the microprocessor 8.

IPC: B29C63/34
Filed: 1985-03-08
Abstract: PURPOSE:To enable to adhere reliably a tube pulled into a tube to the inside of the tube without causing accumulation of air between the tube and a tube wall, by substituting gradually steam introduced through one end side of the tube for the air to be discharged through the other end side of the tube under a pressurized state. CONSTITUTION:Air A whose pressure is low to such an extent as to enable to inflate a tube 2 into a circular cross section is enclosed into the tube 2, to begin with, and then steam is sent into the tube through an inlet 7 by opening a valve 6 while the pressure is being kept on. The air A is discharged slowly while the pressure, through which an information state of the tube can be kept on, is being kept on by opening a valve 9. When steam B is substituted for the air A like this, the steam in the inside of the tube advances to an outlet side gradually as the steam is interrupted by the low-pressure air. Heating also of the tube progresses slowly from an inlet side of the steam, the tube is inflated in order from an inlet side wherein mechanical strength has been deteriorated due to softening of the tube and adheres closely to a wall of the tube even if the pressure in the inside of the tube is kept balanced and the air which has sojourned between the wall of the tube and the tube is discharged without being left behind.

Title: Color facsimile signal transmission system
Inventor: MURASE KATSUO
IPC: H04N1/64
Filed: 1979-04-18
Abstract: PURPOSE: To transmit a color facsimile signal so that it can be compatible with a white black facsimile signal, by utilizing a three valued AM modulation and setting a level of a color signal to an upper level than a white black signal level.  
     CONSTITUTION: A white black picture signal W.B and a color picture signal COL are obtained by scanning an original. W.B and COL are input to the level setting and addition circuit 1, and COL is set to an upper level than that of W.B and is added. This added output is subject to an AM modulation by converting to a three valued signal. The receiving side demodulates a three valued AM modulation input, and subsequently converts it to a two valued signal by the three value → two value converter 5. As for the two valued signal, its level is decided by the level decision device 6, and COL is extracted. Thus, a color facsimile signal and a white black facsimile signal can be transmitted and received compatibly.

Filed: 1979-04-18
Abstract: PURPOSE: To simplify the construction of the circuit by providing an inspection circuit commonly used in items to be inspected and comparing each piece of information in normal states memorized beforehand individually for the items to be inspected with the results of the inspection.  
     CONSTITUTION: The contact 3 of a pass selection relay PSR is closed by a drive timing signal from a control part 10, and, at the same time, the transistor Q of a drive circuit 1 is turned on to excite a switch magnet 4. At this time, when the transistor is in normal state, -48V is supplied from a drive line 2 to an inspection circuit 9 via a protective circuit 6, and when the transistor Q is in off-state, the ground becomes an input of the circuit 9 via magnet 4, contact 3, drive line 2 and a circuit 6. Accordingly, at the time of on-state inspection, when the circuit 1 operate normally, the inspection output signal A becomes an "L" level. If the memorized information pieces of the items to be on-state-inspected are in "L" levels, the values obtained by the comparison coincide to each other, and therefore it is determined that the result of the inspection is satisfactory. By these procedures, the construction of the circuit can be simplified.
