Title: High-speed analog/digital converter
Inventor: NAKAMURA HIROSHI
IPC: H03M1/00
Filed: 1983-06-14
Abstract: PURPOSE:To obtain a high-speed A/D converter by producing a surplus output signal and to code it into a lower digit digital signal. CONSTITUTION:An input analog voltage signal VIN is converted into an upper digital signal b4 from b1 by an upper digit digital coding A/D converter 2 and also into a surplus output signal for alternating binary coding by an alternating binary coding surplus output converting circuit 22. This output signal is converted into a lower digit digital signal b4' from b1' by a lower digit digital coding A/D converter 8. Therefore the processing speed is extremely increased for A/D conversion since a surplus output signal is obtained concurrently with an upper digit digital signal.

Title: Carry circuit
Inventor: SAEKI YUKIHIRO
IPC: H03K23/52
Filed: 1984-05-24
Abstract: PURPOSE:To attain high speed operation of a carry circuit by adding an MOSFET to each carry section except a carry section for the most significant bit. CONSTITUTION:MOSFETs 47-45 are added. Since a drain of an FET26 for precharge of the carry section 51 of the most significant bit is connected directly to a circuit point 22, the level of the circuit point 22 rises sufficiently up to a power supply potential VC. On the other hand, circuit points 54-52 to which a drain of precharge FETs 25-23 is connected in carry sections 50-48 of a low- order bit are separated by the FETs 47-45. The potential of level 1 at circuit points 21-19 does not rise up to the power supply potential VC and reaches a potential less by a threshold potential of the FETs 47-45. Thus, since the amount of electric charge to be discharged is reduced, the high speed operation is attained.

Title: Electromagnet device and electromagnetic relay
Inventor: KITAMURA TSUNEHIRO
IPC: H01F7/14
Filed: 1989-04-25
Abstract: PURPOSE:To prevent the efficiency of attracting force of an electromagnet from dropping and reduce the fluctuation of the attracting property of the magnet by magnetically coupling a core with armature so that the flat surface of one piece of the armature can be brought into contact with the end face of the core. CONSTITUTION:A coil 2 is wound around a core 1 after winding stopping members 6 and 7 are mounted on the core 1. Then a yoke 3 is fixed to the core 1 and the locking pieces 5d and 5d of a supporting spring 5 firmly fitted with an armature 4 are locked to the recessed part 6a of the member 6. As a result, the flat surface 4f of the armature 4 and the yoke 3 are respectively brought into contact with the end face 1c of the core 1 and both magnetic pole sections 3d and 4d of the armature 4. Then such a semi-assembled electromagnet device is joined with a body 10 and, in such state, the coil 2 is excited. Accordingly, the magnetic pole section 4d of the armature 4 is attracted to the magnetic pole section 3d of the yoke 3 and both sections 3d and 4d makes areal contact with each other. Since a plate spring 20 for fixation fixes the armature 4 together with the spring 5, a decline in the efficiency of the attracting force and attracting characteristics caused by the fluctuation of each parts can be reduced.

Title: Linear solid-state image pickup element
Inventor: NISHIZAWA SHIGEKI
IPC: H04N5/365
Filed: 1990-04-23
Abstract: PURPOSE:To prevent adverse effect on a picture due to the dispersion in the characteristic of an element in a selected path by amplifying a picture element signal outputted according to the ratio of the capacitance of a photo diode and a readout use capacitor so as to obtain a readout signal based on a precharge voltage. CONSTITUTION:A voltage signal corresponding to a signal charge in a photo diode D1 is given to an output capacitor C1 via an amplifier MOSFETQ21 and a readout switch MOSFETQ31 and when the capacitor C1 is charged up by a voltage corresponding to the signal charge of the photo diode D1, the switch MOSFETQ2 is turned off. Thus, the other electrode of the capacitor C1 is brought into a floating state. Then precharge operation is started to the photo diode D1 by a shift register SR. Since the signal charge given to a holding capacitor is based on the precharge voltage, the dispersion in the process of a precharge MOSFETQ11 is cancelled into zero.

IPC: B66C23/94
Filed: 1988-04-28
Abstract: PURPOSE:To control the turning inertia of a jib to be within a predetermined range and prevent an external force from acting on a turning driving portion or an excessive lateral load from acting on the jib by regulating the turning speed in accordance with a suspending load. CONSTITUTION:At the time of the lifting up/down operation of a material, etc., a suspending load which acts on a boom end generates a command signal corresponding to the detected load within the division of each stage of the detected suspending load set in multiple stages in a suspending load detector 10 linked to the end of a sling 7. This command signal is transmitted to an oil pressure control mechanism and subjected to signal conversion by a control portion consisting of an amplifier and a controller to operate an electromagnetic proportion valve in accordance with a current value inputted into the solenoid thereof. Thereupon, the feeding quantity of an operating oil into a turning driving motor is restricted, shifting the turning driving speed thereof from a steady condition to a lower speed as the suspending load gets larger. Hence, at the time of turning a jib 4, the turning inertia is not increased because of the suspending load to enable turning in a stable condition.
