Title: Multiplier core circuit
Inventor: KIMURA KATSUHARU
IPC: G06G7/163
Filed: 1994-11-30
Abstract: PURPOSE: To provide a multiplier core circuit which has linearity and can operate at a low voltage by combining new input voltages. CONSTITUTION: When a 1st voltage signal and a 2nd voltage to be multiplied are denoted as VY and VX, a 1st transistor(TR) 11 is applied with VX-VY and a 2nd TR 12 is applied with a voltage 2VX. Further, a 3rd TR 13 is applied with a voltage VX and a 4th TR 14 is applied with a voltage 2VX-VY respectively. The input voltages are converted into the combination like this manner and applied to the TRs 1-14 to obtain a multiplier having linear characteristics excluding the influence of a threshold voltage. Further, the four TRs 11-14 are driven with the common tail current, and consequently while an input is floated, the multiplier core circuit is given limiting characteristics.

IPC: G06F3/02
Filed: 1988-11-25
Abstract: PURPOSE:To reduce power consumption, and to improve operation reliability by forming an optical path of an optical fiber cable. CONSTITUTION:The optical fiber cable 2 is arranged inside a black-coated optical path wall 3, and the optical path is constituted of the dual structure of this optical path wall 3 and the optical fiber cable 2.

Title: Deviation correction of component mounting position
Inventor: OTA MASANORI
IPC: B23P19/00
Filed: 1988-11-25
Abstract: PURPOSE:To enable the correction of an electronic component positional deviation without giving any damage to the electronic component by a method wherein the positional deviation of the component in the directions of theta, X, and Y are obtained basing on the state that the component is sucked by a nozzle through an optical image processing means, and a printed board is positionally adjusted basing on the obtained deviation value. CONSTITUTION:When an electronic component is held as being sucked by a suction nozzle from a electronic component feeding means, it is checked by various sensors if the suction nozzle holds the component or not and the position of the component sucked by the nozzle is right or not. By this check, when it is confirmed that the nozzle holds the component right in position, the suction nozzle is made to turn by making a pulse motor or the like pivot corresponding to a specified program, whereby the sucking position of the component is set to a direction of theta. Then, the deviation of the component mounting position from a printed board in the directions of theta, X, and Y are obtained through an optical image processing means. The printed board placed on an X-Y table is positionally adjusted based on the deviation obtained through the image processing means. By this setup, the correction of a component positional deviation in the directions of theta, X, and Y can be made through an optical image processing means and a simple connection system without giving any physical damage to the component.

Abstract: PROBLEM TO BE SOLVED: To make a mold clamping device compact in the forward/backward direction by providing a flange for fitting to a rear plate on a motor and fitting a gear for mold thickness adjustment into the outer peripheral face of the flange to support/slide the gear. SOLUTION: A rotor 36 is rotated by supplying current to a coil 37 and this rotation is transmitted to a ball nut 40 through an output shaft 32. Consequently, the rotary motion of the ball nut 40 in the arrow A direction is converted to the linear motion in the arrow B direction of a ball treaded shaft 42 by screwing the ball nut 40 into the ball threaded shaft 42, and the ball threaded shaft 42 and a cross head are reciprocated by a stroke. That is, a toggle mechanism is stretched to make a movable platen advance by moving the cross head forward and thus an operation to close and clamp a mold is performed. The toggle mechanism bends and the movable platen moves back to open the mold by making the cross head recede.

Abstract: PURPOSE:To perform a software test at a high speed and to save the testing labor by storing the information inputted to an input device into an input simulation device and outputting repetitively the information to the software from the input simulation device. CONSTITUTION:In a test mode an operator switches a switch 4 to the B side to connect a simulator 3 to the software 2. Then an output control part 32 gives an output instruction to a storage part 31 in response to a simulator test instruction of the operator. The part 31 outputs its storing data to a conver sion part 33, and the part 33 converts adversely the received data into the information of a form outputted from a mouse 1. As the switch 4 is connected to the software 2, the information is given to the software 2 in the same form as that outputted from the mouse 1. Then the part 32 gives the output instructions to the part 31 for the prescribed times. Thus, the same information is repetitively sent to the software. In such a constitution, the software 2 is tested at a high speed and at the same time the testing labor is saved.

Cement milk is then injected below into the soft slime solid S' and the excavator 1 is pulled up under a condition that the soft slime solid S' is placed on the excavating head 2. Concrete 3 is then placed into the pit B and a custom- made pile is penetrated by fixing its tip in the concrete. The slime can thus be exactly removed out, and a sufficient bearing capacity can be provided to the in-situ concrete pile. The bearing capacity obtained is higher than that by the conventional cement-milk construction work.
