Title: Method for excavating slanted bedrock at highly elevated position
Inventor: TOMITA MINORU
IPC: B66F9/06
Filed: 1999-04-02
Abstract: PROBLEM TO BE SOLVED: To facilitate the replacement of a bedrock excavating device, facilitate the movement of the bedrock excavating device on a slanted surface, ensure the safety, and increase a working efficiency in excavating a bedrock slanted surface. SOLUTION: A method for excavating a bedrock at elevated position uses a working deck 4 mounted horizontally, swingably, and drivingly through a posture holding member 5 at the tip part of a telescoping boom mounted swingably and drivingly prostrating and erecting on a carriage and a bedrock excavating device 6 mounted on the deck 4. Because the working deck 4 is of a simple rectangular type, it can be replaced easily irrespective of the shape of the bedrock excavating device 6. Also, because the rock excavating device 6 is installed on the working deck 4 installed horizontally, swingably, and drivingly through the posture holding member 5 at the tip of the telescoping boom installed swingably, elevatably, and drivingly prostrating and erecting, the working can be performed always on a stable scaffold. In addition, because the movement on the slanted surface can be performed easily, a working efficiency can be increased safely.

Abstract: PROBLEM TO BE SOLVED: To ensure bonding property between a circuit board and conductors and enable bonding to multi-pin narrow-pitch IC chips, in a method of electrically connecting the IC chip to the circuit board through conductors formed by wire bonding. SOLUTION: This method comprises the steps of forming a bump 6 on a land 4 at a secondary side of a wire bonding by ball bonding with a first ball 5a and a step of ball bonding with a second ball 5b of a diameter smaller than that of a first ball 5a and wire bonding to form a conductor 10 with a pad 3a set at the primary side and the bump 6 at the secondary side, thereby electrically connecting an IC chip 3 and a circuit board 1. Thus the land 4 ensures the bonding property with the first large-diameter ball 5a and the pad 3a prevents extrusion, etc., with the second small-diameter ball 5b, thereby bonding to the multi-pin narrow-pitch IC chip 3.

Title: Precipitation apparatus employing transverse flow tilting plates
Inventor: MOCHIZUKI TADAO
IPC: B01D21/02
Filed: 1991-05-08
Abstract: PURPOSE:To remarkably improve precipitation separation efficiency, inhibit the precipitated substances from becoming suspension again, and prevent the formation of density flow even if the suspension is dense by installing a proper number of tilting plates horizontally and in parallel at distances in each space between neighboring and reversely tilting plates which tilt in the opposite direction to the formers. CONSTITUTION:In each space between neighboring and tilting plates K, reversely tilting plates K' which tilt in the opposite direction to the plates K are installed horizontally and in parallel while keeping gap F between each two plates. Consequently, the supernatant liquid C produced in the back sides of the reversely tilting plates K' moves upward and joins with the supernatant liquid C in the back sides of the tilting plates K and the resulting supernatant liquid moves upward while passing the gap F. On the other hand, the suspension particles S which precipitate on the surface side of the reversely tilting plates K' slip down on the reversely tilting plates K' and join with the suspension particles S which precipitate on the surface of the tilting plates K and slip down on the tilting plates K and the resulting particles fall downward through the gap F. As a result, the ascending course of the supernatant liquid and the slipping down route of the suspension particles do not cross and the supernatant liquid and the suspension particles are led to the water surface part and bottom part, respectively.

Title: Fs modulator-demodulator
Inventor: YAMANE MASANORI
IPC: H04L27/12
Filed: 1994-06-14
Abstract: PURPOSE:To relieve the distortion of a bit time by changing the oscillation frequency of a voltage signal in response to the phase difference of both frequencies by a predetermined filter means. CONSTITUTION:A phase comparator 5 outputs a voltage signal corresponding to a phase difference between a selection frequency fr0 and a reference frequency f0 to a LPF 6 and its output is applied to a voltage controlled oscillator 8. When the level of transmission data is changed from 0 to 1, since the voltage signal corresponding to the level change is not applied to the voltage controlled oscillator 8, a pass band of a band pass filter 10 and a received frequency are yet unchanged. Since the LPF 6 has a predetermined time constant till the voltage signal corresponding to a change in the transmission data reaches the oscillator 8, a predetermined time delay is produced. Thus, even when the level of the transmission data changes from 0 to 1, a frequency change in the band pass filter 10 and a transmission line is moderated and the difference between the frequency change and the transmission time becomes very small, resulting that distortion in a bit time is reduced.
